Background

In the third Generation Partnership Project (3 GPP), Carrier Aggregation (CA) is used in a Long Term Evolution Advanced system (LTE-a), and the CA may acquire a larger bandwidth by aggregating a plurality of continuous or discontinuous Component Carriers (CC), thereby improving a peak data rate and a system throughput, and solving a problem of discontinuous spectrum of an operator.

User Equipment (UE) can support aggregation of multiple CCs in downlink and uplink, the CCs may be located in the same frequency band or different frequency bands, the aggregated CCs are collectively referred to as serving cells of the UE, and the CCs correspond to the serving cells one to one, and may be used together in concept. Generally, a serving Cell configured by a UE includes a Primary Cell (PCell) and 1 to 4 Secondary cells (scells).

In release 10 of LTE-a, a CA supports aggregation of CCs from the same base station, supports simultaneous transmission of a Physical Uplink Shared CHannel (PUSCH) and a Physical Uplink Control CHannel (PUCCH), and the PUCCH is configured only to the PCell, and the base station (eNB) determines a configuration situation where PUCCH transmission and PUSCH transmission are performed simultaneously for the UE, and the UE completes simultaneous PUCCH transmission and PUSCH transmission according to the configuration of the base station.

With the continuous development of LTE-a technology, an application scenario that PUCCH transmission can also be supported on a certain SCell is introduced in release 12 of LTE-a, that is, the situation of configuring PUCCH for UE is changed, and how a base station configures transmission behavior of UE and how the UE responds to configuration of the base station becomes an urgent problem to be solved in the art for such a change.

All other embodiments that can be derived by one skilled in the art from the embodiments given herein are intended to be within the scope of the invention.

The terms "first," "second," and the like in the description and in the claims, and in the drawings described above, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and are merely descriptive of the invention in its embodiments for distinguishing between objects of the same nature. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of elements is not necessarily limited to those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

The following are detailed below.

Referring to fig. 1, first, a method for simultaneously transmitting uplink multiple channels according to an embodiment of the present invention is described from a base station side, and specifically includes the following steps 101 and 102.

101. A base station (eNB) obtains user equipment capability information of a User Equipment (UE).

Wherein the user equipment capability information comprises: the Uplink Control CHannel indication method includes first indication information for indicating whether a baseband of the UE supports simultaneous Physical Uplink Control CHannel (PUCCH, abbreviated in english) and Physical Uplink Shared CHannel (PUSCH, abbreviated in english), second indication information for indicating Uplink Carrier Aggregation (CA) capability of the UE, and third indication information for indicating whether a band corresponding to a Secondary Cell (SCell, abbreviated in english) of the UE supports Uplink discontinuous transmission capability.

In the embodiment of the present invention, the base station may specifically obtain the capability information of the UE through interaction with the UE, and the base station may also obtain the capability information of the UE through a Mobile Management Entity (MME), where communication between the base station and the UE may be completed through a wireless network, and communication between the base station and the MME may be realized through a standard interface between the base station and the MME, for example, an S1 interface.

In some embodiments of the present invention, the UE capability information acquired by the base station to the UE may include various contents, for example, in release 12 of LTE-a, uplink discontinuous transmission supporting a PUCCH on a certain SCell is introduced, and in these application scenarios, the UE capability information acquired by the base station to the UE may specifically include the following contents: 1. the base band (english name is base band) of the UE supports capability information for simultaneous PUCCH transmission and PUSCH transmission, 2, uplink CA capability information of the UE, and 3, uplink discontinuous transmission capability information of the UE on the band of the SCell configured with the PUCCH.

In some embodiments of the present invention, for content 1 carried in the UE capability information, there are two cases whether the baseband of the UE supports simultaneous PUCCH transmission and PUSCH transmission: 1) the base band of the UE can support simultaneous PUCCH transmission and PUSCH transmission, and 2) the base band of the UE does not support simultaneous PUCCH transmission and PUSCH transmission. If the base band of the UE belongs to the case 1), the capability information of the UE for supporting simultaneous PUCCH transmission and PUSCH transmission is supported, and if the base band of the UE belongs to the case 2), the capability information of the UE for supporting simultaneous PUCCH transmission and PUSCH transmission is not supported. For example, whether the baseband of the UE supports simultaneous PUCCH transmission and PUSCH transmission may be represented by a simultaneous PUCCH-PUSCH-release 10 (sinultaneouspucch-PUSCH-r 10) information element, which is a baseband-specific feature of the UE and is determined by the capability of the UE itself, regardless of the frequency band.

For content 2 carried in the UE capability information, uplink Carrier Aggregation (CA) capability information of the UE may refer to band information and CC bandwidth capability information of the UE supporting the uplink CA, and specifically, the uplink carrier aggregation capability information of the UE may include: 1) the band information of the SCell where the UE is configured with the PUCCH and the UE has CA capability, 2), the band information of the PCell and the UE has CA capability, when the UE is specifically implemented, the uplink carrier aggregation capability information may include 1) or not, the uplink carrier aggregation capability may further include 2) or not 2), that is, the uplink carrier aggregation capability information may be implemented in four ways, that is, in a first implementation, in a case including 1) and 2), in a second implementation, in a case not including 1) and 2), in a third implementation, in a case not including 1) and 2), and in a fourth implementation, in a case not including 1) and 2). In other embodiments of the present invention, further, the uplink carrier aggregation capability information may further include a band list supporting uplink CA within and/or between bands, and capability information such as the number and bandwidth of CCs, the number of layers of Multiple Input Multiple Output (MIMO), and the like, for example, the uplink carrier aggregation capability information may be obtained according to frequency band combination information reported by the UE, for example, by supporting a frequency band combination-version 10 (supported band combination-r10) cell, and by introducing a new band combination cell to represent an uplink carrier aggregation capability signal of the UE.

For content 3 carried in the UE capability information, there are two cases for the UE to perform uplink discontinuous transmission capability on the band (english name band) of the SCell configured with PUCCH: 1) the UE can support uplink discontinuous transmission on the frequency band of the SCell configured with the PUCCH, 2) the UE does not support uplink discontinuous transmission on the frequency band of the SCell configured with the PUCCH, if the UE belongs to the situation of 1), the UE supports the uplink discontinuous transmission capability information on the frequency band of the SCell configured with the PUCCH, and if the UE belongs to the situation of 2), the UE does not support the uplink discontinuous transmission capability information on the frequency band of the SCell configured with the PUCCH. For example, whether the UE supports uplink discontinuous transmission in the band of the SCell configured with the PUCCH may be represented by an intra-carrier uplink discontinuous transmission information-release 10 (english name: nonconsecusouusul-RA-withcc-Info-r 10) information element, which is a band-specific feature of the UE, and whether to support uplink discontinuous transmission is determined by the capability of the UE itself. The SCell configured with PUCCH means that the SCell can support PUCCH transmission, and may also be interpreted as a capability that PUCCH transmission is configured on the SCell.

In other embodiments of the present invention, the ue capability information further includes: and fourth indication information for indicating whether the UE supports uplink discontinuous transmission capability on a frequency band corresponding to a Primary Cell (PCell). For the fourth indication information carried in the UE capability information, there are two cases for the uplink discontinuous transmission capability of the UE on the PCell frequency band: 1) the UE may support uplink discontinuous transmission on the frequency band of the PCell, 2) the UE does not support uplink discontinuous transmission on the frequency band of the PCell, if the UE belongs to 1), the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell is supported, and if the UE belongs to 2), the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell is not supported. For example, whether the UE supports uplink discontinuous transmission in the band of the PCell may be represented by a noccontiguous ul-RA-withcc-Info-r 10 information element, which is a band-specific feature of the UE, and whether the uplink discontinuous transmission is supported is determined by the capability of the UE itself.

102. The base station transmits a radio resource control connection reconfiguration message (RRC connection reconfiguration, english name) to the UE. When the user equipment capability information meets the transmission condition, the radio resource control connection reconfiguration message carries transmission indication information, the transmission indication information is used for indicating that the UE can transmit the PUCCH on the SCell, and the UE can transmit the PUSCH while transmitting the PUCCH on the SCell.

The transmission condition is used for indicating the base station that the UE can perform PUCCH transmission on the SCell, and the SCell is configured with the PUCCH, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell.

It should be noted that, in the above embodiment, the transmission indication information indicates "indicating that the UE can perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission," and the specific meaning of the transmission indication information indicates that the transmission indication information first "indicates that the UE can perform PUCCH transmission on the SCell," and the transmission indication information also indicates that "the UE can perform PUSCH transmission while the UE performs PUCCH transmission on the SCell," and the transmission indication information also indicates that "the UE can perform PUCCH transmission on the SCell" and "the UE can perform PUSCH transmission" are performed simultaneously, that is, for the transmission of the PUSCH, the UE indicates that the UE can perform PUSCH transmission on the SCell, and specifically, various implementation cases are described in the following embodiments.

In the embodiment of the present invention, after the base station acquires the UE capability information of the UE, the base station parses the acquired UE capability information, and according to different specific contents included in the UE capability information, the base station determines that PUCCH transmission and PUSCH transmission can be simultaneously configured for the UE, specifically, the base station determines that "the UE can be configured to perform PUCCH transmission on the SCell and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission", or the base station determines that "the UE cannot be configured to perform PUCCH transmission on the SCell and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission". It should be noted that, the signals transmitted when the UE performs PUCCH transmission and PUSCH transmission may specifically refer to control signaling or may refer to data streams, and the base station determines that the UE can be configured to perform PUCCH transmission on the SCell, and when the UE performs PUCCH transmission on the SCell, the UE can perform PUSCH transmission depending on the specific content of the user equipment capability information acquired in step 101, and the base station may have different determination results for different specific contents, which is described in detail below.

In other embodiments of the present invention, for example, in release 12 of LTE-a, the attribution of PCell and Scell in the UE is divided, and there may be multiple cell groups in the UE, for example, a first PUCCH cell group (british name PUCCH cell group 1), a second PUCCH cell group (british name PUCCH cell group 2), or there may be more cell groups in the UE, for example, a third PUCCH cell group (british name PUCCH cell group 3), and so on. In addition, in some application examples of the invention, the SCell configured with the PUCCH and not belonging to the PUCCH cell group1 and the other SCells configured with the PUCCH and not belonging to the SCell in the PUCCH cell group2 form PUCCH cell group 3. In the embodiment of the invention, any SCell can only belong to one PUCCH cell group. It should be noted that, in the subsequent embodiments of the present invention, PUCCH cell group1 and PUCCH cell group2 of the UE are used for description, and for the remaining PUCCH cell groups (for example, PUCCH cell group 3, etc.) in the UE, the implementation method may refer to the implementation method of PUCCH cell group2, and is not described one by one for each PUCCH cell group.

In some embodiments of the invention, the transmission conditions include: the first indication information is for indicating support, the third indication information is for indicating support, and the second indication information is for indicating band information of the SCell and that the UE has CA capability.

In this case, the transmission indication information is used to indicate that the UE is capable of performing transmission of PUCCH on the SCell, and the UE is capable of performing transmission of PUSCH on the second PUCCH cell group while the SCell is performing transmission of PUCCH; and the second PUCCH cell group comprises the SCell and other SCells.

That is, the contents of the first indication information, the second indication information, and the third indication information are respectively determined, and when the first indication information is used to indicate support, the third indication information is used to indicate support, and the second indication information is used to indicate band information of the SCell, and the UE has CA capability, the base station may determine that the UE is configured to be able to perform PUCCH transmission on the SCell, and the UE is configured to be able to perform PUSCH transmission on the second PUCCH cell group while the SCell is transmitting PUCCH. In addition, the aforementioned second PUCCH cell group includes an SCell and other scells. Wherein, the other scells may refer to scells without PUCCH configuration.

Further, the transmission of the PUSCH can be performed in the second PUCCH cell group while the SCell performs the transmission of the PUCCH, which may specifically include the following steps:

carrying out PUCCH transmission and PUSCH transmission on the SCell at the same time;

or,

and carrying out PUCCH transmission on the SCell and PUSCH transmission on other SCells at the same time.

That is, in the above-described embodiment, there are two cases, first: performing PUCCH transmission and PUSCH transmission simultaneously on the SCell, and secondly: and carrying out PUCCH transmission on the SCell and PUSCH transmission on other SCells at the same time. That is, the SCell with PUCCH configured can transmit PUCCH and PUSCH at the same time, and the SCell without PUCCH configured (i.e., the aforementioned "other SCell") can only transmit PUSCH.

In other embodiments of the present invention, the ue capability information further includes: fourth indication information for indicating whether the UE supports uplink discontinuous transmission capability on a frequency band corresponding to the PCell; the transmission conditions include: the first indication information indicates support, the third indication information indicates support, the fourth indication information indicates support, and the second indication information indicates band information of a PCell, band information of an SCell, and CA capability of the UE.

In this case, the transmission indication information is used to indicate that the UE can perform PUCCH transmission on the SCell, or the SCell and the PCell, and the UE can perform PUSCH transmission on the first PUCCH cell group and the second PUCCH cell group while the SCell performs PUCCH transmission; the second PUCCH cell group comprises an SCell and a second other SCell, the first PUCCH cell group comprises a PCell and a first other SCell, and the second other SCell is an SCell which is not configured with a PUCCH and is different from the first other SCell.

That is, when the fourth indication information is included in the UE capability information, the base station may further indicate the UE to use the PCell through the transmission indication information, and then the base station may further indicate that the UE performs PUCCH transmission in two cases: 1. the UE can perform PUCCH transmission on the SCell, and 2, the UE can perform PUCCH transmission on the SCell and the PCell. And for the base station to instruct the UE to perform PUSCH transmission, the base station further indicates that the PUSCH transmission is performed in the first PUCCH cell group and the second PUCCH cell group.

Further, when the SCell transmits the PUCCH, the PUSCH may be transmitted in the first PUCCH cell group and the second PUCCH cell group, which may specifically include the following steps:

meanwhile, PUCCH transmission is carried out on the PCell, PUCCH and PUSCH transmission is carried out on the SCell, and PUSCH transmission is carried out on the first other SCell and/or the second other SCell;

or,

and simultaneously, PUCCH transmission is carried out on the SCell, PUCCH and PUSCH transmission is carried out on the PCell, and PUSCH transmission is carried out on the first other SCell and/or the second other SCell.

That is, in the first case, the PCell performs PUCCH transmission, the SCell performs PUCCH and PUSCH transmission, and the first other SCell in the PUCCH cell group1 and/or the second other SCell in the PUCCH cell group2 performs PUSCH transmission. In the second case, the SCell performs PUCCH transmission, the PCell performs PUCCH and PUSCH transmission, and the PUSCH transmission is performed on the first other SCell in the PUCCH cell group1 and/or the second other SCell in the PUCCH cell group 2.

The following detailed example is directed to the detailed determination process in the above embodiment, in which the base station determines whether the UE can perform PUCCH transmission on the SCell, and the UE can perform the PUSCH transmission while performing PUCCH transmission on the SCell, and the UE can perform the PUSCH transmission:

in some embodiments of the present invention, the determining, by the base station, that the UE can be configured to perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell may specifically include:

For content 1, content 2, content 3, and content 4, the base station needs to confirm specific representation contents of various capability information, for example, as can be seen from the foregoing description, there may be two types of representation contents for the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH: "support" or "not support", in the same manner, after the base station determines the contents of content 1, content 2, content 3, and content 4 in step a1, when the UE supports uplink discontinuous transmission capability information on the band of the SCell configured with the PUCCH, and the base band of the UE supports the capability information of simultaneous PUCCH transmission and PUSCH transmission as support, and the uplink CA capability information of the UE includes band information of the SCell and the UE has CA capability, when the prerequisite condition for the execution of step a2 is satisfied, the base station can execute the contents described in step a2, that is, the base station determines that it can be configured that the UE can perform transmission of PUCCH on the SCell, and the UE can perform transmission of PUCCH on the SCell at the same time, the UE is capable of transmission of the PUSCH, the UE may perform transmission of the PUCCH on the SCell according to the determination result of the base station, and the UE can perform transmission of the PUSCH while the SCell performs transmission of the PUCCH. In the embodiments described herein, in the case that the SCell configured with the PUCCH of the UE supports PUCCH transmission, how the base station determines whether to configure the UE to perform uplink multi-channel simultaneous transmission is specifically described, and the UE may also perform uplink multi-channel simultaneous transmission according to the configuration of the base station.

In other embodiments of the present invention, determining, by the base station, that the UE can be configured to perform PUCCH transmission on the SCell, and while the UE performs PUCCH transmission on the SCell, the UE can perform PUSCH transmission, specifically including the following steps:

a3, when the base band of the UE supports simultaneous PUCCH transmission and PUSCH transmission, the uplink CA capability information of the UE comprises the frequency band information of the UE on the SCell configured with the PUCCH, the frequency band information of the UE on the PCell and the CA capability of the UE, the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH is supported, and the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell is not supported, the base station determines that the UE can be configured to perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission.

In step a1, the base station determines the following contents according to the UE capability information: whether the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH is supported or not, whether the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell is supported or not, whether the base band of the UE supports simultaneous PUCCH transmission and PUSCH transmission or not, and uplink CA capability information of the UE. For the content of each capability information, the base station needs to confirm the specific representation content of the capability information, for example, as can be seen from the foregoing description, there may be two types of representation contents for the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH: "support" or "not support", the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell may have two indications: "support" or "not support". Only when the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell is not supported, and the remaining three conditions are all supported or include correspondingly required contents, a prerequisite condition that the execution of step A3 is satisfied occurs, the base station may execute the contents described in step A3, that is, the base station determines that the UE can be configured to perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission, the UE needs to execute the determination result according to the base station, that is, the UE can perform PUCCH transmission on the SCell in this case, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission. In the embodiments described herein, for the case that all scells configured with PUCCH of the UE support PUCCH transmission, how the base station determines whether to configure the UE to perform uplink multi-channel simultaneous transmission is specifically described, and the UE may not perform uplink multi-channel simultaneous transmission according to the configuration of the base station.

In step a1, the base station determines the following contents according to the UE capability information: l, whether uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH is supported, 2, whether capability information of the UE supporting simultaneous PUCCH transmission and PUSCH transmission is supported by the baseband, 3, uplink CA capability information of the UE, 4, whether uplink discontinuous transmission capability information of the UE on the frequency band of the PCell is supported, and the base station needs to confirm specific representation contents of the capability information, for example, it can be known from the foregoing description that there may be two types of representation contents for the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH: "support" or "not support", the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell may have two indications: "support" or "not support". After the base station determines the content indicated by the capability information in step a1, only when the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH is not supported and all of the remaining three types of capability information support or include the content that is correspondingly required, the prerequisite condition that the execution of step a4 is satisfied occurs, the base station may execute the content described in step a4, that is, the base station determines that the transmission of the PUCCH cannot be configured on the SCell for the UE, and the UE can perform the transmission of the PUSCH while performing the transmission of the PUCCH on the SCell, the UE needs to execute the determination result according to the base station, that is, the UE cannot perform the transmission of the PUCCH on the SCell in this situation, and the UE can perform the transmission of the PUSCH while performing the transmission of the PUCCH on the SCell. In the embodiments described herein, for the case that both the PCell of the UE and the SCell configured with the PUCCH support PUCCH transmission, how the base station determines whether to configure the UE for uplink multi-channel simultaneous transmission is described specifically, and the UE may not perform uplink multi-channel simultaneous transmission according to the configuration of the base station.

In other embodiments of the present invention, for example, in release 12 of LTE-a, the attribution of PCell and Scell in the UE is divided, and there may be multiple cell groups in the UE, for example, a first PUCCH cell group (british name PUCCH cell group 1), a second PUCCH cell group (british name PUCCH cell group 2), or there may be more cell groups in the UE, for example, a third PUCCH cell group (british name PUCCH cell group 3), and so on. In addition, in some application examples of the invention, the SCell configured with the PUCCH and not belonging to the PUCCH cell group1 and the other SCells configured with the PUCCH and not belonging to the SCell in the PUCCH cell group2 form PUCCH cell group 3. In the embodiment of the invention, any SCell can only belong to one PUCCH cell group. It should be noted that, in the subsequent embodiments of the present invention, PUCCH cell group1 and PUCCH cell group2 of the UE are used for description, and the implementation method of the remaining PUCCH cell groups (PUCCH cell group 3) in the UE may be implemented by referring to the implementation method of PUCCH cell group2, and each PUCCH cell group is not described one by one.

a5, when the capability information of the base band of the UE supporting simultaneous PUCCH transmission and PUSCH transmission is UE, the uplink CA capability information of the UE comprises the frequency band information of the UE on the SCell configured with the PUCCH, the frequency band information of the PCell of the UE and the CA capability of the UE, the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH is not supported, and the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell is supported, the base station determines that the simultaneous PUCCH transmission and PUSCH transmission can be configured on PUCCH cellgroup 1 for the UE, and the simultaneous PUCCH transmission and PUSCH transmission can not be configured on PUCCH cellgroup2 for the UE.

In step a1, the base station determines the following contents according to the UE capability information: 1. whether uplink discontinuous transmission capability information of the UE on a frequency band of the SCell configured with the PUCCH is supported, 2 whether capability information of the UE supporting simultaneous PUCCH transmission and PUSCH transmission is supported, 3, whether uplink CA capability information of the UE, and 4, whether uplink discontinuous transmission capability information of the UE on a frequency band of the PCell is supported. For the content 1, content 2, content 3, and content 4 base stations all need to confirm the specific representation content of the capability information, for example, as can be seen from the foregoing description, there may be two types of representation contents for the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH: "support" or "not support", the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell may have two indications: "support" or "not support". After the base station determines the foregoing content in step a1, when the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH is not supported and the remaining three contents are all supported or include the corresponding required contents, a prerequisite condition that the execution of step a5 is satisfied occurs, and the base station may execute the content described in step a5, that is, the base station determines that it is possible to configure simultaneous transmission of the PUCCH and transmission of the PUSCH on the PUCCH cell group1 for the UE and it is not possible to configure simultaneous transmission of the PUCCH and transmission of the PUSCH on the PUCCH cell group2 for the UE, because the scells configured with the PUCCH and the PCell belong to PUCCH cell group1 and PUCCH cell group 2.

If the frequency band of the SCell configured with the PUCCH does not support uplink discontinuous transmission, the base station determines that the UE cannot configure the PUCCH and transmit the PUSCH on the PUCCH cell group2 at the same time aiming at the PUCCH cell group2 where the SCell configured with the PUCCH is located. If the frequency band of the PCell supports uplink discontinuous transmission, for a PUCCH cell group1 where the PCell is located, the base station determines that the UE can configure simultaneous PUCCH transmission and PUSCH transmission on the PUCCH cell group 1. That is, the base station determines whether the UE can simultaneously perform PUCCH transmission and PUSCH transmission on one PUCCH cell group without affecting whether the UE can simultaneously perform PUCCH transmission and PUSCH transmission on another PUCCH cell group, and when the base station determines that only PUCCH transmission and PUSCH transmission can be simultaneously performed on PUCCH cell group X (X is 1, 2, 3, etc.), the UE can simultaneously perform PUCCH transmission and PUSCH transmission only on PUCCH cell group X according to the instruction of the base station. In the embodiment described herein, for the case that both the PCell of the UE and the SCell configured with the PUCCH support PUCCH transmission, how the base station determines whether the configured UE can perform uplink multi-channel simultaneous transmission on the PUCCH cell group is described specifically, and the UE may also perform uplink multi-channel simultaneous transmission or not perform uplink multi-channel simultaneous transmission on the PUCCH cell group according to the configuration of the base station.

a6, when the capability information of the base band of the UE supporting simultaneous PUCCH transmission and PUSCH transmission is UE, the uplink CA capability information of the UE comprises the frequency band information of the UE on the SCell configured with the PUCCH, the frequency band information of the PCell of the UE and the CA capability of the UE, the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH is supported, and the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell is not supported, the base station determines that the simultaneous PUCCH transmission and PUSCH transmission can be configured on PUCCH cellgroup2 for the UE, and the simultaneous PUCCH transmission and PUSCH transmission can not be configured on PUCCH cellgroup 1 for the UE.

In step a1, the base station determines the following contents according to the UE capability information: 1. whether uplink discontinuous transmission capability information of the UE on a frequency band of the SCell configured with the PUCCH is supported, 2 whether capability information of the UE supporting simultaneous PUCCH transmission and PUSCH transmission is supported, 3, whether uplink CA capability information of the UE, and 4, whether uplink discontinuous transmission capability information of the UE on a frequency band of the PCell is supported. For the content 1, content 2, content 3, and content 4 base stations all need to confirm the specific representation content of the capability information, for example, as can be seen from the foregoing description, there may be two types of representation contents for the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH: "support" or "not support", the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell may have two indications: "support" or "not support". After the base station determines the foregoing content in step a1, when the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell is not supported and the remaining three contents are all supported or include the correspondingly required content, a prerequisite condition that the execution of step a6 is satisfied occurs, and the base station may execute the content described in step a6, that is, the base station determines that the PUCCH transmission and the PUSCH transmission can be configured and simultaneously performed on PUCCH cell group2 for the UE and the PUCCH transmission and the PUSCH transmission can not be configured and simultaneously performed on PUCCH cell group1 for the UE, because the scells configured with the PUCCH and the PCell belong to PUCCH cell group1 and PUCCH cell group 2.

If the band of the SCell configured with the PUCCH supports uplink discontinuous transmission, the base station determines that the UE can configure the PUCCH and transmit the PUSCH simultaneously on the PUCCH cell group2 for the PUCCH cell group2 where the SCell configured with the PUCCH is located. If the frequency band of the PCell does not support uplink discontinuous transmission, aiming at the PUCCH cell group1 where the PCell is located, the base station determines that the UE cannot configure simultaneous PUCCH transmission and PUSCH transmission on the PUCCH cell group 1. That is, the base station determines whether the UE can simultaneously perform PUCCH transmission and PUSCH transmission on one PUCCH cell group without affecting whether the UE can simultaneously perform PUCCH transmission and PUSCH transmission on another PUCCH cell group, and when the base station determines that only PUCCH transmission and PUSCH transmission can be simultaneously performed on PUCCH cell group X (X is 1, 2, 3, etc.), the UE can simultaneously perform PUCCH transmission and PUSCH transmission only on PUCCH cell group X according to the instruction of the base station, and does not simultaneously perform PUCCH transmission and PUSCH transmission on PUCCH cell groups other than PUCCH cell group X. In the embodiment described herein, for the case that both the PCell of the UE and the SCell configured with the PUCCH support PUCCH transmission, how the base station determines whether the configured UE can perform uplink multi-channel simultaneous transmission on the PUCCH cell group is described specifically, and the UE may also perform uplink multi-channel simultaneous transmission or not perform uplink multi-channel simultaneous transmission on the PUCCH cell group according to the configuration of the base station.

a7, when the capability information of the base band of the UE supporting simultaneous PUCCH transmission and PUSCH transmission is UE, the uplink CA capability information of the UE comprises the frequency band information of the UE on the SCell configured with the PUCCH, the frequency band information of the PCell of the UE and the CA capability of the UE, the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH is supported, and the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell is supported, the base station determines that the UE can be configured on PUCCH cell group2 for simultaneous PUCCH transmission and PUSCH transmission, and can be configured on PUCCH cell group1 for simultaneous PUCCH transmission and PUSCH transmission.

In step a1, the base station determines the following contents according to the UE capability information: 1. whether uplink discontinuous transmission capability information of the UE on a frequency band of the SCell configured with the PUCCH is supported, 2 whether capability information of the UE supporting simultaneous PUCCH transmission and PUSCH transmission is supported, 3, whether uplink CA capability information of the UE, and 4, whether uplink discontinuous transmission capability information of the UE on a frequency band of the PCell is supported. For the content 1, content 2, content 3, and content 4 base stations all need to confirm the specific representation content of the capability information, for example, as can be seen from the foregoing description, there may be two types of representation contents for the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH: "support" or "not support", the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell may have two indications: "support" or "not support". After the base station determines that the above-mentioned content is supported by the UE in step a1, when the uplink discontinuous transmission capability information of the UE on the band of the SCell configured with the PUCCH is supported, and the uplink discontinuous transmission capability information of the UE on the band of the PCell is supported, and the other two capability information are supported or include the corresponding required content, the pre-condition that the execution of step a7 is satisfied occurs, and the base station may execute the content described in step a7, that is, the base station determines that the PUCCH transmission and the PUSCH transmission can be configured simultaneously for the UE on the PUCCH cell group2, and can configure the PUCCH transmission and the PUSCH transmission simultaneously for the UE on the PUCCH cell group1, because the PUCCH cell and the configured PUCCH belong to PUCCH cell group1 and PUCCH cell group2, wherein, if the band of the SCell configured with the PUCCH supports uplink discontinuous transmission, the PUCCH cell group2 where the SCell configured with the PUCCH is located, the base station determines that the UE can configure simultaneous PUCCH transmission and PUSCH transmission on PUCCH cellgroup 2. If the frequency band of the PCell supports uplink discontinuous transmission, for a PUCCH cell group1 where the PCell is located, the base station determines that the UE can configure simultaneous PUCCH transmission and PUSCH transmission on the PUCCH cell group 1.

That is, the base station determines whether the UE can simultaneously perform PUCCH transmission and PUSCH transmission on one PUCCH cell group without affecting whether the UE can simultaneously perform PUCCH transmission and PUSCH transmission on another PUCCH cell group, and when the base station determines that the PUCCH transmission and PUSCH transmission can be simultaneously performed on both PUCCH cell group1 and PUCCH cell group2, the UE can simultaneously perform PUCCH transmission and PUSCH transmission on PUCCH cell group1 and PUCCH transmission and PUSCH transmission on PUCCH cell group2 according to the instruction of the base station. In the embodiment described herein, for the case that both the PCell of the UE and the SCell configured with the PUCCH support PUCCH transmission, how the base station determines whether the configured UE can perform uplink multi-channel simultaneous transmission on the PUCCH cell group is described specifically, and the UE may also perform uplink multi-channel simultaneous transmission on the PUCCH cell group according to the configuration of the base station.

a8, when the capability information of the base band of the UE supporting simultaneous PUCCH transmission and PUSCH transmission is UE support, the uplink CA capability information of the UE comprises the frequency band information of the UE on the SCell configured with the PUCCH, the frequency band information of the PCell of the UE and the CA capability of the UE, the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH is support, and the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell is support, the base station determines that the UE can be configured on the SCell configured with the PUCCH to simultaneously perform PUCCH transmission and PUSCH transmission.

In step a1, the base station determines the following contents according to the UE capability information: 1. whether uplink discontinuous transmission capability information of the UE on a frequency band of the SCell configured with the PUCCH is supported, 2 whether capability information of the UE supporting simultaneous PUCCH transmission and PUSCH transmission is supported, 3, whether uplink CA capability information of the UE, and 4, whether uplink discontinuous transmission capability information of the UE on a frequency band of the PCell is supported. For the content 1, content 2, content 3, and content 4 base stations all need to confirm the specific representation content of the capability information, for example, as can be seen from the foregoing description, there may be two types of representation contents for the uplink discontinuous transmission capability information of the UE on the frequency band of the SCell configured with the PUCCH: "support" or "not support", the uplink discontinuous transmission capability information of the UE on the frequency band of the PCell may have two indications: "support" or "not support". After the base station determines the above content in step a1, when the UE is supported by the uplink discontinuous transmission capability information on the band of the SCell configured with the PUCCH, the UE is supported by the uplink discontinuous transmission capability information on the band of the PCell, and the other two capability information are supported or include the corresponding required content, the prerequisite condition for performing step A8 is met, and the base station may perform the content described in step A8, that is, the base station determines that the PUCCH transmission and PUSCH transmission may be performed simultaneously for the UE on the SCell configured with the PUCCH. That is, if the band of the SCell configured with the PUCCH of the UE supports uplink discontinuous transmission and the band of the PCell supports uplink discontinuous transmission, in this case, if the base station determines that the UE is configured to simultaneously perform transmission of the PUCCH and transmission of the PUSCH only on the SCell configured with the PUCCH, the UE performs transmission of the PUCCH and transmission of the PUSCH simultaneously according to the determination result of the base station, that is, the UE performs transmission of the PUCCH and transmission of the PUSCH on the SCell configured with the PUCCH. In the embodiments described herein, in the case that only PCell of the UE and the SCell configured with PUCCH supports PUCCH transmission, how the base station determines whether the UE can be configured to perform uplink multi-channel simultaneous transmission is specifically described, and the UE may also determine on which Cell to perform uplink multi-channel simultaneous transmission according to the configuration of the base station.

It should be noted that, in the above embodiments of the present invention, the base station parses the content indicated by the UE capability information, then the base station determines whether the UE can be configured to perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell, in other embodiments of the present invention, the base station determines whether the UE can be configured to perform PUCCH transmission on the SCell, and the UE need not be limited to the UE capability information while performing PUCCH transmission on the SCell, and the UE may also use the UE capability information in combination with other information to determine whether the UE can be configured to perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell.

For example, the base station may further determine information such as uplink maximum transmission power information, cell load information, scheduling decision information, and the like, to comprehensively determine whether the UE can be configured to perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell, for example, the base station may set an uplink maximum transmission power threshold, determine that the UE cannot be configured to perform PUCCH transmission on the SCell when the uplink maximum transmission power value exceeds the threshold, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell, and further determine whether the UE can be configured to perform PUCCH transmission on the SCell when the uplink maximum transmission power value does not exceed the threshold, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell, and for example, the base station may refer to the cell load condition, when the symbols of the PCell or the SCell are overloaded, the base station determines that the UE cannot be configured to perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission, when the load of the cell is small or in an bearable range, the base station further determines whether the UE can be configured to perform PUCCH transmission on the SCell in combination with the user equipment capability information, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission, for example, the base station determines whether the UE can be configured to perform PUCCH transmission on the SCell in combination with the user equipment capability information according to a preset scheduling decision, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission.

In this embodiment of the present invention, after determining whether the UE is configured for the UE and can perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell, the base station triggers execution of step 102, where the base station sends a radio resource control connection reconfiguration message to the UE, and the determination result of the base station may also be described by carrying transmission indication information in the radio resource control connection reconfiguration message, and the UE knows whether PUCCH transmission can be performed on the SCell through the transmission indication information, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell.

It should be noted that, in some embodiments of the present invention, when the UE capability information does not satisfy the transmission condition, the rrc connection reconfiguration message does not carry transmission indication information or the rrc connection reconfiguration message carries non-synchronization transmission indication information, where the non-synchronization transmission indication information is used to indicate that the UE cannot perform PUCCH transmission on the SCell. That is, if the base station determines that it is not possible to configure the UE for PUCCH transmission on the SCell, and the UE is capable of PUSCH transmission while the SCell is transmitting PUCCH, the base station may not carry the transmission indication information in the rrc connection reconfiguration message, or indicate the transmission indication information through another message.

In some embodiments of the present invention, when the base station determines that the UE can be configured to perform PUCCH transmission on the SCell, and the UE is capable of performing PUSCH transmission while the SCell performs PUCCH transmission, the rrc connection reconfiguration message carries simultaneousucch-PUSCH-r 10 information element, and a value of simultaneousucch-PUSCH-r 10 information element is true (english name "true") to indicate that the UE performs PUCCH transmission on the SCell, and the UE is capable of performing PUSCH transmission while the SCell performs PUCCH transmission. The simultaneouspcch-PUSCH-r 10 information element is included in the transmission indication information.

It is to be understood that, when the rrc connection reconfiguration message carries the indication information, the indication information may be represented by using an information element already existing in release 10 of LTE-a, for example, simultaneousucch-PUSCH-r 10 information element, and the value of simultaneousucch-PUSCH-r 10 information element generally includes one of: true (true) and indicates different meanings in the radio resource control connection reconfiguration message by whether simultaneousucch-PUSCH-r 10 cell is contained or not, in the embodiment of the present invention, a value of simultaneousucch-PUSCH-r 10 cell is used to indicate that the UE can perform PUCCH transmission on the SCell by using a value of simultaneousucch-PUSCH-r 10 cell as true to indicate that the UE can perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell by not including simultaneousucch-PUSCH-r 10 cell in the radio resource control connection reconfiguration message to indicate that the base station cannot configure PUCCH transmission on the SCell for the UE, and while performing PUCCH transmission on the SCell, the UE can perform PUSCH transmission.

In other embodiments of the present invention, the transmission indication information includes simultaneousucch-PUSCH-r 10 cell for the first PUCCH cell group and simultaneousucch-PUSCH-r 10 cell for the second PUCCH cell group, where a value of the simultaneousucch-PUSCH-r 10 cell for the first PUCCH cell group is true for indicating that the UE can perform transmission of PUSCH on the first PUCCH cell group while performing transmission of PUCCH on the SCell, and a value of the simultaneousucch-PUSCH-r 10 cell for the second PUCCH cell group is true for indicating that the UE can perform transmission of PUSCH on the second PUCCH cell group while performing transmission of PUCCH on the SCell.

For example, in release 12 of LTE-a, the attribution of PCell and Scell in UE is divided, there may be multiple cell groups in UE, such as PUCCH cell group1, PUCCH cell group2, or there may also be more cell groups in UE, such as PUCCH cell group 3, etc., as can be known from the foregoing description of the embodiments, the base station may determine whether the UE can perform PUCCH transmission and PUSCH transmission simultaneously for PUCCH cell group1 and PUCCH cell group2, respectively, then the rrc connection reconfiguration message sent by the base station may also indicate for PUCCH cell group1 and PUCCH cell group2, specifically, when the base station determines that the UE can be configured to perform PUCCH transmission and PUSCH transmission simultaneously, the rrc connection reconfiguration message carries simultaneousucch-PUCCH-r 10 for PUCCH cell group1 and simultaneousPUCCH-PUSCH-group-10 for PUSCH cell group2, the value of the simultaneousUCCH-PUSCH-r 10 cell for the PUCCH cell group1 is true to indicate that the UE can simultaneously transmit the PUCCH and the PUSCH on the PUCCH cell group1, and the value of the simultaneousUCCH-PUSCH-r 10 cell for the PUCCH cell group2 is true to indicate that the UE can simultaneously transmit the PUCCH and the PUSCH on the PUCCH cell group 2. The UE may perform simultaneous PUCCH transmission and PUSCH transmission for the PUCCH cell group1 and the PUCCH cell group2 by parsing the indication information of the rrc connection reconfiguration message.

In other embodiments of the present invention, the transmission indication information includes simultaneousucch-PUSCH-r 10 cell and intraCC PUCCH-PUSCH-r12 cell, and the value of simultaneousucch-PUSCH-r 10 cell is true for indicating that the UE is capable of performing transmission of PUSCH, and the value of intraCC PUCCH-PUSCH-r12 cell is true for indicating that the UE is capable of performing transmission of PUCCH on SCell.

For example, when the uplink discontinuous transmission capability information of the UE on the band of the SCell configured with the PUCCH is supported, and the uplink discontinuous transmission capability information of the UE on the band of the PCell is supported, the base station determines that PUCCH transmission and PUSCH transmission can be simultaneously configured for the UE on the SCell configured with the PUCCH, in this implementation scenario, the rrc connection reconfiguration message carries a PUCCH-PUSCH-release 12 (intra-cc PUCCH-PUSCH-r12) cell within a component carrier, and a value of the intra-cc PUCCH-PUSCH-r12 cell is true for indicating that the UE performs PUCCH transmission on the SCell configured with the PUCCH, and the intra-cc PUCCH-PUSCH-r12 cell is included in the transmission indication message.

It should be noted that, for release 12 of LTE-a, if the base station determines that it can configure the UE to be able to perform PUCCH transmission on the SCell, and the UE is able to perform PUSCH transmission while the SCell performs PUCCH transmission, the base station may use a new cell to indicate in release 10 of LTE-a, in addition to using the simultaneousPUCCH-PUSCH-r10 for indication, for example, an intraCC PUCCH-PUSCH-r12 cell, or of course, another cell may be used to indicate, as long as the normal parsing of this cell by the UE can be satisfied.

As can be seen from the above description of the embodiments of the present invention, a base station first obtains user equipment capability information of a UE, where the user equipment capability information includes: the base station sends a radio resource control connection reconfiguration message to the UE, when the user equipment capability information meets the transmission condition, the radio resource control connection reconfiguration message carries transmission indication information, the transmission indication information is used for indicating that the UE can transmit PUCCH on the SCell, and the UE can transmit PUSCH while the SCell transmits PUCCH. That is to say, the base station needs to use the third indication information, the first indication information, and the second indication information of the uplink discontinuous transmission capability of the UE on the frequency band of the SCell configured with the PUCCH to jointly determine whether the UE can be configured with the PUCCH for transmission on the SCell, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission, and finally carries the transmission indication information in the radio resource control connection reconfiguration message for indication, and the UE can know that the UE performs PUCCH transmission on the SCell according to the transmission indication information carried in the radio resource control connection reconfiguration message, and can perform PUSCH transmission while the SCell performs PUCCH transmission, thereby solving the problem of uplink multichannel simultaneous transmission under the condition that the SCell of the UE supports the PUCCH, and filling the gap in the prior art.

The above embodiment describes the uplink multi-channel simultaneous transmission method provided by the embodiment of the present invention from the base station side, and please refer to fig. 2, the uplink multi-channel simultaneous transmission method provided by the embodiment of the present invention is described from the UE side, which specifically includes the following steps 201, 202, and 203.

201. And the UE receives the radio resource control connection reconfiguration message sent by the base station.

In this embodiment of the present invention, the base station sends a radio resource control connection reconfiguration message to the UE, and the base station may also carry indication information in the radio resource control connection reconfiguration message, for example, when the base station determines that it can configure that the UE can perform transmission of PUCCH on the SCell, and the UE can perform transmission of PUSCH while performing transmission of PUCCH on the SCell, the base station may carry transmission indication information in the radio resource control connection reconfiguration message, where the transmission indication information is used to indicate that the UE can perform transmission of PUCCH on the SCell, and the UE can perform transmission of PUSCH while performing transmission of PUCCH on the SCell.

In some embodiments of the present invention, before the UE receives the rrc connection reconfiguration message sent by the base station in step 201, the method for simultaneously transmitting uplink multiple channels according to the embodiment of the present invention may further include the following steps:

the UE sends UE capability information to a base station or a Mobility Management Entity (MME).

That is to say, in the embodiment of the present invention, the UE capability information acquired by the base station may be acquired from the UE or the MME, the UE may report its own UE capability information to the base station, the base station determines whether PUCCH transmission can be configured on the SCell for the UE, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell.

Further, the user equipment capability information may specifically include at least one of the following: the base band of the UE supports first indication information for indicating whether a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH) are simultaneously carried out, second indication information for indicating the uplink Carrier Aggregation (CA) capability of the UE and third indication information for indicating whether the frequency band corresponding to the secondary cell (SCell) of the UE supports uplink discontinuous transmission capability. For the specific content analysis of the capability information of the user equipment, please refer to the description in the foregoing embodiments, which is not described herein again.

202. The UE analyzes transmission indication information from the radio resource control connection reconfiguration message, wherein the transmission indication information is used for indicating that the UE can transmit PUCCH on the SCell and can transmit PUSCH at the same time when the SCell transmits PUCCH.

Wherein the SCell is configured with PUCCH.

In the embodiment of the present invention, after receiving the rrc connection reconfiguration message from the base station, the UE parses the transmission indication information according to the content indicated by the rrc connection reconfiguration message, and the UE can obtain, from the transmission indication information carried in the rrc connection reconfiguration message, that the UE can perform PUCCH transmission on the SCell, and can perform PUSCH transmission while performing PUCCH transmission on the SCell, so that the UE can know that the base station determines that the UE can be configured to perform PUCCH transmission on the SCell, and can perform PUSCH transmission while performing PUCCH transmission on the SCell.

In some embodiments of the present invention, the analyzing, by the UE, the UE transmission indication information from the rrc connection reconfiguration message may specifically include the following steps:

and the UE analyzes a simultaneousUCCH-PUSCH-r 10 cell carried in the radio resource control connection reconfiguration message, and if the value of the simultaneousUCCH-PUSCH-r 10 cell is true, the UE determines that the PUSCH can be transmitted while the SCell transmits the PUCCH.

That is, if the base station carries the simultaneousucch-PUSCH-r 10 cell in the rrc connection reconfiguration message, and the simultaneousucch-PUSCH-r 10 cell is included in the transmission indication information, the UE may determine, from the value of the simultaneousucch-PUSCH-r 10 cell as true, that the base station has configured, for the UE, the capability of performing PUSCH transmission while the SCell is capable of performing PUCCH transmission.

In other embodiments of the present invention, for example, in release 12 of LTE-a, the attribution of PCell and Scell in the UE is divided, and there may be multiple cell groups in the UE, for example, PUCCH cell group1, PUCCH cell group2, or there may be more cell groups in the UE, for example, PUCCH cell group 3, and so on. In this application scenario, the UE may analyze the UE transmission indication information from the rrc connection reconfiguration message, and specifically includes the following steps:

the UE analyzes simultaneousUCCH-PUSCH-r 10 information elements aiming at PUCCH cell group1 and simultaneousUCCH-PUSCH-r 10 information elements aiming at PUCCH cell group2 carried in the radio resource control connection reconfiguration message;

if the value of simultaneousPUCCH-PUSCH-r10 cell for PUCCH cell group1 is true, the UE determines that the transmission of the PUCCH can be carried out on the SCell and the PUSCH can be carried out on the first PUCCH cell group at the same time;

if the simultaneousucch-PUSCH-r 10 cell for PUCCH cell group2 takes the value of true, the UE can perform transmission of PUCCH on the SCell and transmission of PUSCH on the second PUCCH cell group at the same time.

That is, the base station makes specific indications as to whether the UE configures simultaneous PUCCH transmission and PUSCH transmission on PUCCH cell group1 and PUCCH cell group2, respectively, so the UE may determine whether PUCCH transmission and PUSCH transmission may be performed simultaneously for PUCCH cell group1 and PUCCH cell group2 by respective values of simultaneousucch-PUSCH-r 10 cell for PUCCH cell group1 and simultaneousucch-PUSCH-r 10 cell for PUCCH cell group 2.

In other embodiments of the present invention, if the bmc reconfiguration message carries the simultaneousucch-PUSCH-r 10 cell and the intraCC PUCCH-PUSCH-r12 cell, and the value of the simultaneousucch-PUSCH-r 10 cell is true, the value of the simultaneousucch-PUSCH-r 10 cell is used to indicate that the UE can perform PUSCH transmission, and the value of the intraCC PUCCH-PUSCH-r12 cell is true, the value of the simultaneousucch-PUSCH-r 3526 cell is true, and the value of the intraCC PUCCH-PUSCH-r12 cell is true, the value of the intraCC PUCCH-PUCCH transmission is indicated by the UE.

In this application scenario, the UE may analyze the UE transmission indication information from the rrc connection reconfiguration message, and specifically includes the following steps:

the UE analyzes a simultaneousUCCH-PUSCH-r 10 cell and an intraCC PUCCH-PUSCH-r12 cell carried in a radio resource control connection reconfiguration message, the simultaneousUCCH-PUSCH-r 10 cell and the intraCCPCCH-PUSCH-r 12 cell are included in transmission indication information, if values of the simultaneousUCCH-PUSCH-r 10 cell and the intraCC PUCCH-PUSCH-r12 cell are both true, the UE determines that PUCCH transmission can be carried out on the SCell, and the UE can carry out PUSCH transmission while the SCell carries PUCCH transmission.

That is, the UE may determine whether the UE is capable of performing PUCCH transmission on the SCell by taking the values of the simultaneousucch-PUSCH-r 10 cell and intraCCPUCCH-PUSCH-r12 cell, and the UE is capable of performing PUSCH transmission while the SCell is performing PUCCH transmission.

203. The UE transmits PUCCH on the SCell, and the UE can transmit PUSCH while the SCell transmits PUCCH.

When the UE parses the transmission indication information from the rrc connection reconfiguration message, the UE performs step 203, the UE performs PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission. The UE can perform transmission of PUSCH while performing transmission of PUCCH on SCell, where the UE can perform transmission of PUSCH while performing transmission of PUCCH on SCell may be understood as that the UE can perform transmission of PUSCH while performing transmission of PUCCH on SCell, and the transmission of PUCCH and PUSCH may be transmission signals, where the signals described herein may refer to control signaling or data streams, etc.

In some embodiments of the present invention, for example, in release 12 of LTE-a, the attribution of PCell and Scell in the UE is divided, and there may be multiple cell groups in the UE, for example, a first PUCCH cell group (british name PUCCH cell group 1), a second PUCCH cell group (british name PUCCH cell group 2), or there may also be more cell groups in the UE, for example, a third PUCCH cell group (british name PUCCH cell group 3), and so on. In addition, in some application examples of the invention, the SCell configured with the PUCCH and not belonging to the PUCCH cell group1 and the other SCell configured with the PUCCH and not belonging to the SCell in the PUCCH cell group2 form PUCCH cell group 3. In the embodiment of the invention, any SCell can only belong to one PUCCH cell group. It should be noted that, in the subsequent embodiments of the present invention, PUCCH cell group1 and PUCCH cell group2 of the UE are used for description, and the implementation method of the remaining PUCCH cell groups (PUCCH cell group 3) in the UE may be implemented by referring to the implementation method of PUCCH cell group2, and each PUCCH cell group is not described one by one.

In some embodiments of the present invention, the transmission indication information is used to indicate that the UE is capable of performing transmission of PUCCH on the SCell, and the UE is capable of performing transmission of PUSCH on a second PUCCH cell group while the SCell is performing transmission of PUCCH.

In this application scenario, step 202, the UE performs PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell, and specifically includes the following steps:

the UE transmits PUCCH on the SCell, and can transmit PUSCH on a second cell group while transmitting PUCCH on the SCell; and the second PUCCH cell group comprises the SCell and other SCells.

That is, the base station may determine the contents of the first indication information, the second indication information, and the third indication information, respectively, and when the first indication information is used to indicate support, the third indication information is used to indicate support, and the second indication information is used to indicate band information of the SCell, and the UE has CA capability, the base station may determine that the UE can be configured to be capable of performing PUCCH transmission on the SCell, and the UE can perform PUSCH transmission on a second PUCCH cell group while performing PUCCH transmission on the SCell, where the second PUCCH cell group includes the SCell and other scells. Wherein, the other scells may refer to scells without PUCCH configuration. The UE may perform PUCCH transmission on the SCell according to the transmission indication information of the base station, and the UE may perform PUSCH transmission on the second PUCCH cell group while the SCell performs PUCCH transmission.

It should be noted that, in the above embodiment, the transmission indication information indicates "indicating that the UE can perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission", and the specific meaning of the transmission indication information indicates that the UE can perform PUCCH transmission on the SCell first, and the transmission indication information also indicates that the UE can perform PUSCH transmission while the UE performs PUCCH transmission on the SCell, where "the UE performs PUCCH transmission on the SCell" and "the UE can perform PUSCH transmission" simultaneously, that is, for the transmission of the PUSCH, the UE indicates that the UE can complete PUSCH transmission, and specific implementation cases are also included, which is described in the following embodiments.

Further, in the above step, the UE can perform transmission of a PUSCH in a second cell group while performing transmission of a PUCCH in an SCell, including:

the UE transmits PUCCH and PUSCH at the SCell simultaneously;

or,

and the UE transmits PUCCH on the SCell and transmits PUSCH on other SCells.

In other embodiments of the present invention, the transmission indication information is used to indicate that the UE can perform PUCCH transmission on the SCell, or the SCell and the PCell, and the UE can perform PUSCH transmission on the first PUCCH cell group and the second PUCCH cell group while the SCell performs PUCCH transmission.

the UE transmits PUCCH on the SCell or the SCell and the PCell, and the UE can transmit PUSCH on a first PUCCH cell group and a second PUCCH cell group while transmitting PUCCH on the SCell; the second PUCCH cell group comprises an SCell and a second other SCell, the first PUCCH cell group comprises a PCell and a first other SCell, and the second other SCell is an SCell which is not configured with a PUCCH and is different from the first other SCell.

Further, the UE performs PUCCH transmission on the SCell, or the SCell and the PCell, and the UE can perform PUSCH transmission on the first PUCCH cell group and the second PUCCH cell group while performing PUCCH transmission on the SCell, including:

or,

and the UE simultaneously transmits PUCCH on the SCell, PUCCH and PUSCH on the PCell and PUSCH on the first other SCell and/or second other SCell.

That is, in the first case, the PCell performs PUCCH transmission, the SCell performs PUCCH and PUSCH transmission, and the first other SCell in the PUCCH cell group1 and/or the second other SCell in the PUCCH cell group2 performs PUSCH transmission.

In other embodiments of the present invention, after the UE receives the radio resource control connection reconfiguration message sent by the base station eNB in step 201, the method for simultaneously transmitting uplink multiple channels according to the embodiment of the present invention further includes the following steps:

when the radio resource control connection reconfiguration message does not carry transmission indication information or the radio resource control connection reconfiguration message carries asynchronous transmission indication information, the UE cannot transmit PUCCH on the SCell; the non-synchronized transmission indication information is used for indicating that the UE cannot perform PUCCH transmission on the SCell.

That is, when the base station determines that the UE capability information does not have the transmission condition, the base station may not carry the transmission indication information in the rrc connection reconfiguration message or the rrc connection reconfiguration message carries the asynchronous transmission indication information, and the UE determines that the PUCCH cannot be transmitted on the SCell through the message that the rrc connection reconfiguration message does not carry the transmission indication information, or determines that the PUCCH cannot be transmitted on the SCell through the asynchronous transmission indication information carried in the rrc connection reconfiguration message.

In some embodiments of the present invention, while the SCell transmits the PUCCH, the UE may transmit the PUSCH, and the UE may have various implementations, for example, specifically including the following steps:

the UE transmits PUCCH on the PCell and/or SCell configured with PUCCH, and simultaneously transmits PUSCH on the PCell and/or SCell.

That is, in the above steps, the UE may perform PUCCH transmission in three ways: 1. the UE is on the PCell, 2, the UE is on the SCell configured with the PUCCH, 3, the UE is both on the PCell and the SCell configured with the PUCCH, and in addition, the UE also performs PUSCH transmission when performing PUCCH transmission, and there may be three implementation manners for the UE to perform PUSCH transmission: 1. the UE is on the PCell, 2, on the SCell, 3, on both the PCell and the SCell, and it needs to be noted that when the UE performs PUSCH transmission on the SCell, it means that the UE can perform PUSCH transmission on all scells or on at least one SCell without distinguishing between configuring the PUCCH and not configuring the PUCCH for the SCell.

In other embodiments of the present invention, for example, in release 12 of LTE-a, the attribution of PCell and Scell in the UE is divided, and there may be multiple cell groups in the UE, for example, PUCCH cell group1, PUCCH cell group2, or there may be more cell groups in the UE, for example, PUCCH cell group 3, and so on. In this application scenario, while the SCell transmits the PUCCH, the UE may transmit the PUSCH, and the UE may have various implementation manners, for example, the following steps may be specifically included:

the UE transmits PUCCH and PUSCH simultaneously on PUCCH cell group1, wherein the PUCCH cell group1 comprises: PCell and first other SCell.

That is to say, in the above step, the UE performs PUCCH transmission on PUCCH cell group1, and specifically, the UE may perform PUCCH transmission on PCell of PUCCH cell group 1; the UE simultaneously transmits the PUSCH also on the PUCCH cell group1, and specifically, the UE may transmit the PUSCH on the PCell and/or the SCell of the PUCCH cell group1, where the SCell belonging to the PUCCH cell group1 is the SCell without the PUCCH configured; or,

That is to say, in the above step, the UE performs PUCCH transmission on PUCCH cell group2, specifically, the UE may perform PUCCH transmission on the SCell configured with PUCCH in PUCCH cell group 2; the UE simultaneously transmits the PUSCH also on the PUCCH cell group2, specifically, the UE may transmit the PUSCH on the SCell of the PUCCH cell group2, where the SCell belonging to the PUCCH cell group2 may be divided into two types: one is an SCell configured with PUCCH, and the other is an SCell not configured with PUCCH and not belonging to PUCCH cell group 1; or,

in the above step, the UE transmits the PUCCH on PUCCH cell group2, and specifically, the UE may transmit the PUCCH on the SCell configured with the PUCCH in the PUCCH cell group 2; and the UE simultaneously transmits the PUSCH on the SCell and/or the PCell of the PUCCHcell group2 and/or the PUCCH cell group 1.

the UE transmits PUCCH and PUSCH simultaneously on PUCCH cell group1 and transmits PUCCH and PUSCH simultaneously on PUCCH cell group 2.

That is, in the foregoing embodiment, the UE may perform only simultaneous transmission of the PUCCH and transmission of the PUSCH on the PUCCH cell group1, the UE may also perform only simultaneous transmission of the PUCCH and transmission of the PUSCH on the PUCCH cell group2, and further the UE may perform simultaneous transmission of the PUCCH and transmission of the PUSCH on the PUCCH cell group1 and the UE may perform simultaneous transmission of the PUCCH and transmission of the PUSCH on the PUCCH cell group2 only.

In other embodiments of the present invention, while the SCell performs PUCCH transmission, the UE may perform PUSCH transmission, and the UE may have multiple implementation manners, for example, specifically include the following steps:

the UE transmits PUCCH on the PCell and simultaneously transmits PUSCH on the PCell and/or SCell;

or, the UE performs transmission of the PUCCH on the SCell configured with the PUCCH, and simultaneously performs transmission of the PUSCH on the PCell and/or on the SCell.

That is, in the above steps, the UE performs PUCCH transmission on the PCell, and also performs PUSCH transmission when the UE performs PUCCH transmission, and there may be three implementation manners for the UE to perform PUSCH transmission: 1. the method includes that the UE is on a PCell, 2, the UE is on an SCell, 3, the UE is on both the PCell and the SCell, and it needs to be noted that when the UE transmits the PUSCH on the SCell, the PUSCH transmission can be performed on all the SCells of the UE without distinguishing the SCells from the SCells without configuring PUCCHs. In the above steps, the UE performs PUCCH transmission on the SCell configured with PUCCH, and also performs PUSCH transmission when the UE performs PUCCH transmission, and there may be three implementation manners for the UE to perform PUSCH transmission: 1. the method includes that the UE is on a PCell, 2, the UE is on an SCell, 3, the UE is on both the PCell and the SCell, and it needs to be noted that when the UE transmits the PUSCH on the SCell, the PUSCH transmission can be performed on all the SCells of the UE without distinguishing the SCells from the SCells without configuring PUCCHs.

the UE transmits PUCCH on PCell, simultaneously transmits PUSCH on PCell and/or SCell, and simultaneously transmits PUCCH on SCell with PUCCH configured.

That is, in the above steps, there are two cases when the UE performs PUCCH transmission: 1. the UE is on the PCell, 2, the UE is on the SCell configured with the PUCCH, and cases 1 and 2 are implemented simultaneously, the UE also performs PUSCH transmission when performing PUCCH transmission, and there may be three implementation manners for the UE to perform PUSCH transmission: 1. the method includes that the UE is on a PCell, 2, the UE is on an SCell, 3, the UE is on both the PCell and the SCell, and it needs to be noted that when the UE transmits the PUSCH on the SCell, the PUSCH transmission can be performed on all the SCells of the UE without distinguishing the SCells from the SCells without configuring PUCCHs.

As can be seen from the above description of the embodiments of the present invention, the base station sends the rrc connection reconfiguration message to the UE, and when the UE capability information satisfies the transmission condition, the rrc connection reconfiguration message carries transmission indication information, where the transmission indication information is used to indicate that the UE can perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell. That is to say, the base station needs to use the third indication information, the first indication information, and the second indication information of the uplink discontinuous transmission capability of the UE on the frequency band of the SCell configured with the PUCCH to jointly determine whether the UE can be configured with the PUCCH for transmission on the SCell, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission, and finally carries the transmission indication information in the radio resource control connection reconfiguration message for indication, and the UE can know that the UE performs PUCCH transmission on the SCell according to the transmission indication information carried in the radio resource control connection reconfiguration message, and can perform PUSCH transmission while the SCell performs PUCCH transmission, thereby solving the problem of uplink multichannel simultaneous transmission under the condition that the SCell of the UE supports the PUCCH, and filling the gap in the prior art.

In order to better understand and implement the above-mentioned schemes of the embodiments of the present invention, the following description specifically illustrates corresponding application scenarios.

Referring to fig. 3, a schematic flow chart of interaction between a base station and a UE in the embodiment of the present invention includes:

s01: the base station acquires the capability information of the user equipment.

Specifically, the base station sends an initial context SETUP REQUEST message (initial context SETUP REQUEST) to the MME through the S1 interface, and the MME sends an initial context SETUP RESPONSE message (initial context SETUP RESPONSE) to the base station, where the initial context SETUP RESPONSE message includes the ue capability information. In addition, the base station may also send a user equipment Capability request (referred to as UE Capability Information) to the UE, and the UE sends user equipment Capability Information (referred to as UE Capability Information) according to the request sent by the base station.

The user equipment capability information at least comprises the following information: discontinuous transmission capability of the UE in a frequency band corresponding to the PCell and discontinuous transmission capability information of the UE in a frequency band corresponding to the SCell configured with the PUCCH; and the base band of the UE supports the capability information of simultaneous transmission of the PUCCH and the PUSCH and the uplink CA capability information of the UE.

S02: and the base station judges whether the UE can be configured to transmit PUCCH on the SCell or not according to the user equipment capability information, and the UE can transmit PUSCH while transmitting PUCCH on the SCell.

In an implementation scenario, when discontinuous transmission capability information of a UE in a frequency band corresponding to a PCell is "supported", discontinuous transmission capability information of the UE in a band where an SCell configured with a PUCCH is located is "supported", and capability information of whether the baseband of the UE supports simultaneous transmission of the PUCCH and the PUSCH is "supported", and the uplink CA capability information of the UE at least includes the frequency band information corresponding to the PCell and the frequency band information corresponding to the SCell configured with the PUCCH, and the UE has uplink CA capability, the base station determines that the UE can be configured to perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell.

If the UE is not supported in any of the discontinuous transmission capability information of the frequency band corresponding to the PCell and the discontinuous transmission capability information of the frequency band corresponding to the SCell configured with the PUCCH, the base station judges that the UE can not be configured to perform PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while performing PUCCH transmission on the SCell.

In another scenario, when the discontinuous transmission capability information of the UE in the frequency band corresponding to the PCell is "supported", and the capability information of whether the baseband of the UE supports simultaneous transmission of the PUCCH and the PUSCH is "supported", and the uplink CA capability information of the UE at least includes the frequency band information corresponding to the PCell and the frequency band information corresponding to the SCell configured with the PUCCH, and the UE has the uplink CA capability, the base station determines that the PUCCH and the PUSCH can be configured for simultaneous transmission of the UE in the PUCCH cell group1 (which refers to a cell group including the PCell).

In addition to the above capability being "supported", if the discontinuous transmission capability information of the UE in the frequency band corresponding to the SCell configured with the PUCCH is "supported", the base station determines that PUCCH and PUSCH can be configured for PUCCH cell group2 (the cell group where the SCell configured with the PUCCH is located) for simultaneous transmission; otherwise, the base station judges that the PUCCH and PUSCH can not be configured for simultaneous transmission in the PUCCH cell group 2.

In another scenario, new configuration information "simultaneous transmission of PUCCH and PUSCH within carrier" is introduced for each component carrier, which is represented by cell intraCC _ PUCCH-PUSCH-r12, and if the value of the cell is configured to be "true" (true), it is represented that the carrier supports simultaneous transmission of PUCCH and PUSCH within carrier. The base station can configure the cell if the band corresponding to the carrier supports discontinuous transmission.

When the discontinuous transmission capability information of the UE in the frequency band corresponding to the PCell is "supported", and the capability information of whether the baseband of the UE supports simultaneous transmission of the PUCCH and the PUSCH is "supported", and the uplink CA capability information of the UE at least includes the frequency band information corresponding to the PCell and the frequency band information corresponding to the SCell configured with the PUCCH, and the UE has the uplink CA capability, the base station determines that the PUCCH and PUSCH can be configured for the UE for simultaneous transmission, meaning that the PUCCH and the PCell and/or other scells can be transmitted simultaneously on the PCell, and it is not limited whether the SCell belongs to a PUCCH cell group1 or a PUCCH cell group 2. Whether the UE can perform simultaneous PUCCH and PUSCH transmission within the PUCCH configured SCell also depends on whether the base station configures simultaneous PUCCH and PUSCH transmission within the carrier for the PUCCH configured SCell. If the discontinuous transmission capability information of the UE in the frequency band corresponding to the SCell configured with the PUCCH is 'supported', the base station judges that the PUCCH and the PUSCH in the carrier can be configured for the SCell configured with the PUCCH to be transmitted simultaneously; otherwise, the base station judges that the PUCCH and PUSCH can not be configured for the SCell configured with the PUCCH to be transmitted simultaneously.

S03: the base station sends RRCConnectionReconfiguration information to the UE, and when the base station determines that the UE can be configured to be capable of carrying out PUCCH transmission on the SCell and the UE can carry out PUSCH transmission on the SCell at the same time, the base station contains transmission indication information in the message.

In one application scenario, if the base station decides in S02 that the UE can be configured to be able to perform PUCCH transmission on the SCell, and the UE is able to perform PUSCH transmission while the SCell is performing PUCCH transmission. The base station includes simultaneousucch-PUSCH-r 10 cell in RRCConnectionReconfiguration message, the value of which is set to "true (true)", otherwise does not include simultaneousucch-PUSCH-r 10 cell.

In another application scenario, when the base station determines to configure simultaneous transmission of a PUCCH and a PUSCH for a PUCCH cell group1 of a UE, the RRCConnectionReconfiguration message includes indication information that the PUCCH and the PUSCH in the PUCCH cell group1 can be simultaneously transmitted; if the base station further decides to configure simultaneous transmission of the PUCCH and the PUSCH for the PUCCH cell group2 of the UE, the RRCConnectionReconfiguration message further includes indication information that the PUCCH and the PUSCH in the PUCCH cell group2 can be simultaneously transmitted.

In another application scenario, when the base station determines to configure simultaneous transmission of a PUCCH and a PUSCH for the UE, the RRCConnectionReconfiguration message includes indication information that the PUCCH and the PUSCH can be simultaneously transmitted, a value of a simultaneousPUCCH-PUSCH-r10 cell is set to "true", and if the base station also determines to configure transmission of a PUCCH for an SCell of the UE, an intraCC _ PUCCH-PUSCH-r12 cell for the SCell is set to "true".

S04: the UE receives the RRCConnectionReconfiguration message transmitted by the base station.

S05: the UE parses transmission indication information from the RRCConnectionReconfiguration message, wherein the transmission indication information is used for indicating that the UE can perform PUCCH transmission on the SCell and can perform PUSCH transmission while the SCell performs PUCCH transmission.

S06, the UE performs PUCCH transmission on the SCell, and the UE can perform PUSCH transmission while the SCell performs PUCCH transmission.

In an application scenario of the present invention, the transmission of the PUCCH and the transmission of the PUSCH may include intra-carrier and inter-carrier conditions, and there may be a plurality of implementation manners:

1. carrying out PUCCH transmission on a PCell, and carrying out PUSCH transmission on a certain SCell on a PUCCH cell group 2;

2. simultaneously transmitting PUCCH and PUSCH on the PCell, and simultaneously transmitting PUCCH and PUSCH on the SCell of which PUCCH is supported by PUCCH cell group 2;

3. carrying out PUCCH transmission on a PCell, and carrying out PUSCH transmission on a certain SCell of a PUCCH cell group 1;

4. the PUCCH transmission is performed on the SCell configured with PUCCCH in PUCCH cell group2, and the PUSCH transmission is performed on the other SCell in PUCCH cell group2, and these uplink transmissions may be performed simultaneously.

In an application scenario of the present invention, when the cell simultaneousucch-PUSCH-r 10 for PUCCH cell group1 has a value of "true", the UE may perform PUCCH and PUSCH transmission simultaneously in PUCCH cell group 1. When the information element simultaneousucch-PUSCH-r 10 for PUCCH cell group2 has a value of "true", then the UE may also simultaneously perform PUCCH and PUSCH transmissions at PUCCH cell group 2. If the simultaneousPUCCH-PUSCH-r10 cell aiming at PUCCH cell group2 is not contained in the PUCCH cell group, the UE only carries out PUCCH and PUSCH simultaneous transmission at PUCCHcell group 1; simultaneous transmission of PUCCH and PUSCH may not be possible in PUCCH cell group 2.

In an application scenario of the present invention, when a value of simultaneousPUCCH-PUSCH-r10 cell is "true", the UE may perform PUCCH transmission and PUSCH transmission on the PCell at the same time, may perform PUCCH transmission on the PCell, and may perform PUSCH transmission on any SCell at the same time. When an intraCC-PUCCH-PUSCH-r 12 cell exists for the SCell configured with the PUCCH, the UE can also simultaneously transmit the PUCCH and the PUSCH on the SCell; carrying out PUCCH transmission on the SCell, and carrying out PUSCH transmission on other SCells and/or PCell at the same time; PUCCH transmission is performed on the SCell, and PUCCH transmission is performed on the PCell. If there is no intraCC _ PUCCH-PUSCH-r12 cell for the SCell configuring the PUCCH, transmission of the PUCCH and transmission of the PUSCH cannot be simultaneously performed on the SCell.

As can be seen from the above description of the embodiments of the present invention, the present invention solves the problem of simultaneous transmission of PUCCH and PUSCH by a base station and a UE when PUCCH is configured on both a PCell and a SCell, and fills the gap in the prior art.
