Description

The present invention relates to the field of digital communications, and in particular to a method and apparatus for transmitting a response message. BACKGROUND OF THE INVENTION The rapid development of digital communication systems places higher demands on the reliability of data communication, however, in poor channel, especially in high data rate or high speed mobile environments, multipath interference and Doppler shift Etc. seriously affects system performance. Therefore, effective error control techniques, especially Hybrid Automatic Repeat Request (HARQ) technology, have become the hotspot of communication or research. In the HARQ mode, the code transmitted by the originator not only can detect errors, but also has certain error correction capability. After receiving the codeword, the receiver decoder first checks the error condition. If the error correction capability of the code is within, the error correction is automatically performed. If the error is too much, the error correction capability of the code is exceeded, but the error can be detected. The receiving end sends a decision signal to the sending end through the feedback channel, and requests the sending end to resend the information. In an OFDM system, the correct or error of the transmission is indicated by an Acknowledgement/Negative Acknowledgement (ACK/NACK: Acknowledgement/Negative Acknowledgement), and it is judged whether retransmission is required. The transmitted ACK response message or NACK response message is collectively referred to as a HARQ-ACK response message. Currently, in the downlink HARQ of the Long Term Evolution (LTE), the HARQ-ACK response message of the Physical Downlink Shared Channel (PDSCH) is used by the user equipment (UE: User Equipment) in the current subframe. When there is no physical uplink shared channel (PUSCH: Physical Uplink Shared Channel), it is transmitted on the physical uplink control channel (PUCCH: Physical Uplink Control Channel). As shown in FIG. 1 , a physical uplink control channel occupies one resource block (one resource block occupies 12 subcarriers) in the frequency domain, and two time slots in the time domain, that is, one subframe (1 ms). The number of symbols included varies depending on the cyclic prefix used in the current subframe. In addition, the control channel performs frequency hopping on two time slots to obtain a frequency domain diversity gain. The physical uplink control channel of each UE (User Equipment) in the cell is code division multiplexed. Since the number of UEs that can be multiplexed on one resource block is limited, when the number of UEs that need to simultaneously transmit the physical uplink control channel in the cell exceeds the number of users that can be multiplexed by one resource block, To re-open a resource block, that is, to implement multiplexing of physical uplink control channels of each UE in the cell by means of code division + frequency division. The present invention is directed to the problem of determining and transmitting channel resources of HARQ-ACK. Therefore, for ease of understanding, the PUCCH format la/lb for carrying ACK/NACK is briefly introduced here. In the LTE frequency division duplex system (FDD), since the uplink and downlink subframes are - corresponding,

When the PDSCH contains only one transport block, the UE shall feed back a 1-bit HARQ-ACK response message. When the PDSCH contains two transport blocks, the UE shall feed back a 2-bit HARQ-ACK response message. Therefore, in the LTE FDD system, as shown in FIG. 2, the HARQ-ACK response message is subjected to BPSK/QPSK modulation (corresponding to format la/lb, respectively) to form a modulation symbol, and the modulation symbol is first spread spectrum factor in the frequency domain. 12 spread spectrum (the spread spectrum sequence is a 12-length constant amplitude zero autocorrelation sequence;), and then pass the time domain of a length of 4 Walsh (Wash) code The extension is then mapped to the information symbol corresponding to Control Channel Format 1 as shown in Figure 2, and finally combined with the reference signal to form a time slot to transmit the signal. In the time division duplex (TDD) system of LTE, since the uplink and downlink subframes are no longer corresponding to each other, according to different uplink and downlink subframe configurations, one uplink subframe sometimes needs to feed back HARQ of multiple downlink subframes. - ACK response message, where a plurality of downlink subframes corresponding to one uplink subframe are referred to as a bundling window. In LTE, two types of HARQ-ACK feedback modes are defined: one is the HARQ-ACK bundling mode, and the core idea of the method is to correspond to each downlink subframe that needs to be fed back in the uplink subframe. The HARQ-ACK response message of the codeword stream is logically ANDed. If a downlink subframe has 2 codeword streams, the UE needs to feed back a 2-bit HARQ-ACK response message. If each subframe has only one word stream, the UE needs The one-bit HARQ-ACK response message is fed back, and the bundled HARQ-ACK response message is sent by using PUCCH format la or lb; the other is HARQ-ACK multiplexing mode (also known as HARQ-ACK multiplexing). With channel selection, also known as channel selection, the core idea of this mode is to use different PUCCH channels and different modulation symbols on the channel to indicate different feedback states of the downlink subframes that need to be fed back in the uplink subframe, if downlink If there are multiple codeword streams on the subframe, the HARQ-ACK response message fed back by the multiple codeword streams of the downlink subframe is spatially logically (also called spatial bundling), and then channel selection is performed. It is then sent using PUCCH format lb. That is, the HARQ-ACK response message after the spatial logic and operation is represented by the 2-bit information b(0) and b(1) carried by the PUCCH format lb, and the index of the PUCCH channel. In the LTE system, the UE has two ways to determine the channel resource index of the PUCCH for carrying the HARQ-ACK response message: one is obtained through high layer signaling, and the other is through PDCCH (Physical Downlink Control Channel, physical The implicit mapping relationship of the first index of the CCE (Control Channel Element) where the downlink control channel is located is obtained. Thus, in an uplink carrier, the channel resource region of the HARQ-ACK response message is divided into two regions, one is an area configured by higher layer signaling, and the other is a dynamic area implicitly mapped according to an index of a CCE of the PDCCH. After obtaining the channel resource index ⁿ H of the PUCCH, the UE can calculate the resource block index actually used when the UE sends the HARQ-ACK response message according to the channelization formula specified by the protocol, and the time domain orthogonal code used. The index and the amount of cyclic shift of the corresponding CAZAC sequence. In the International Mobile Telecommunications-Advanced (ΙΜΤ-Advanced) system, it can realize high-speed data transmission and has large system capacity. In the case of low-speed mobile and hotspot coverage, the IMT-Advanced system The peak rate can reach 1Gbit/s. In the case of high-speed mobile and wide-area coverage, the peak rate of the IMT-Advanced system can reach 100Mbit/s. In order to meet the requirements of the International Telecommunication Union-Advanced (ITU-Advanced), the Long Term Evolution Advanced (LTE-A) system, which is the evolution standard of LTE, needs to support larger systems. Bandwidth (up to 100MHz) and requires backward compatibility with existing LTE standards. Based on the existing LTE system, the bandwidth of the LTE system can be combined to obtain a larger bandwidth. This technology is called Carrier Aggregation (CA) technology, which can improve the IMT-Advance system. The spectrum utilization, mitigation of spectrum resources shortage, and optimize the utilization of spectrum resources.

? After I enters carrier aggregation, in the current discussion about the relationship between downlink component carriers and PDSCH transport blocks and HARQ processes, a basic working assumption is that when no space division multiplexing is used, one downlink component carrier corresponds to one PDSCH transport block and one HARQ. The process, that is, the UE needs to feed back 1-bit HARQ-ACK response information for one PDSCH transport block of each component carrier. When using space division multiplexing, LTE-A currently specifies up to 2 transport blocks. Therefore, when space division multiplexing is used, the UE needs to feed back a 2-bit HARQ-ACK response message for 2 PDSCH transmission blocks of each downlink component carrier. In the LTE-A FDD system after spectrum aggregation technology, the uplink bandwidth and the downlink bandwidth may include multiple component carriers. When the base station has a PDSCH scheduled for a certain UE on multiple downlink component carriers, and when the UE does not transmit the PUSCH in the current subframe, the user equipment needs to feed back on the PUCCH of one UE-specific UL PCC/Pcell. HARQ-ACK response message of PDSCH transmission of downlink component carriers. In the TDD system, due to the asymmetry of the uplink and downlink subframe configuration, one uplink subframe needs to feed back the HARQ-ACK response information of the PDSCH of the multiple downlink subframes. Therefore, the user equipment needs to feed back the HARQ-ACK with a larger load. Reply message. For ACK/NACK response messages, LTE-A adds a new DFT-s-OFDM based format, in addition to PUCCH format la and lb, which have been defined in LTE, with channel selection. The ACK/NACK response message for transmitting a larger load is shown in FIG. 3. The structure is referred to as PUCCH Format 3 (PUCCH format 3) for convenience of description. Which method the UE uses to feed back the HARQ-ACK is configured by the upper layer. In the LTE-A FDD system, regarding the feedback of HARQ-ACK, two modes are defined: one is a channel selection mode, which can support up to 4 bits of HARQ-ACK feedback; the other is DFT-s-OFDM mode. The mode can support more than 4 bits of HARQ-ACK feedback; wherein, the UE uses which manner to feed back the HARQ-ACK by the higher layer configuration, and specifies that when the UE is configured to use the DFT-s-OFDM mode, if the UE If only the primary downlink component carrier/cell (DL PCC/Pcell) is received in the current subframe, the UE will use the PUCCH format la/lb resource to feed back the HARQ-ACK response message. In the LTE-A TDD system, the HARQ-ACK feedback is further refined based on the FDD configuration mode: When the user equipment is configured to use the PUCCH format 3 feedback HARQ-ACK:

Mode 1 : Supports up to 20 bits of HARQ-ACK feedback; if the number of HARQ-ACK bits fed back exceeds 20, spatial bundling is performed; if the number of HARQ-ACK bits fed back does not exceed 20, No need to perform any kind of binding operation ( bundling ); Mode 2: When the number of bits of the HARQ-ACK exceeds x, the HARQ-ACK bit to be fed back is required by means of component carrier binding (CC bundling) or time bundling on the basis of spatial binding. The number is limited to X bits; the specific value of X is not determined at the end; whether or not to support mode 2 is further discussed. When the user equipment is configured to use the channel selection feedback HARQ-ACK:

Mode a: The number of HARQ-ACK bits fed back does not exceed 4, and does not require any form of binding. Mode b: If the number of HARQ-ACK bits fed back exceeds 4, the HARQ-ACK bit to be fed back is required by means of component carrier binding (CC bundling) or time bundling on the basis of spatial binding. The number is limited to ⁴ bits; specifically whether the component carrier binding or the time binding is not yet determined; Regarding the resource allocation problem in the above various HARQ-ACK feedback modes, the current conclusion is:

In the FDD system, when the UE is configured to use the DFT-s-OFDM feedback HARQ-ACK, the PUCCH format 3 resource is configured by the higher layer signaling (RRC signaling) + ARI (A/N Resource indicator, A/N resource indicator). Dynamic indication, ARI is implemented by reusing DCC's TPC (Transmit Power Control) domain. In the FDD system, when the UE is configured to use the channel selection feedback ACK/NACK, since the mapping table design in the channel selection mode has not been finalized, there is no conclusion as to how to determine the PUCCH format la/lb resource used. In addition, for a UE configured to use channel selection feedback, if the UE receives only the primary downlink component carrier/cell (DL PCC/Pcell) in the current subframe, how the UE will feedback does not give a solution. For the multiple HARQ-ACK feedback methods in the TDD system, how to determine the corresponding resources has no corresponding solution. In addition, in the TDD system, for the user equipment configured as carrier aggregation, when the user equipment only receives the transmission of the primary downlink component, how to feed back the HARQ-ACK response message in each corresponding subframe. It can be seen from the above analysis that the UE has multiple configurations, and in some cases, there is no specific scheme for feeding back the HARQ-ACK, so that the UE cannot complete the transmission of the HARQ-ACK, thereby affecting the performance of the network.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. FIG. 4 is a flowchart of a method for sending a response message according to the embodiment. The method includes the following steps: Step S402: When the terminal needs to send a response message, determine the current system type; wherein the response message is a correct response. a message ACK or an error response message NACK; the system type includes: an FDD system and a TDD system; Step S404, the terminal determines a feedback mode of the response message, the feedback mode includes: a channel selection mode and a PUCCH format 3; Step S406, the terminal is Determining, according to the determined system type and the feedback mode, the PUCCH resource that sends the response message; Step S408, the terminal sends the response message by using the determined PUCCH resource. The method for determining the PUCCH resource for sending the response message may be different according to the determined system type and the feedback mode. The method is as follows: Mode 1: The system type determined by the terminal is an FDD system, and the feedback mode is a channel. When the mode is selected, step S406 includes: determining whether the corresponding PDCCH of the configured serving cell is sent on the primary serving cell; If yes, determining a PUCCH resource for transmitting a response message according to an implicit mapping relationship between the PUCCH resource and the PDCCH; if not, determining a PUCCH resource for transmitting a response message according to the PUCCH resource configured in the upper layer and the resource indicator ARI in the PDCCH. Determining, according to the implicit mapping relationship between the PUCCH resource and the PDCCH, the PUCCH resource for sending the response message includes: determining, according to an index of the control channel unit of the PDCCH, a PUCCH resource that sends a response message. For example, when the serving cell corresponding to the PDCCH is configured to include the transmission mode of the two transport blocks, the terminal determines two PUCCH resources according to the control channel unit index of the PDCCH, and uses the determined two PUCCH resources as the two transport blocks. When the serving cell corresponding to the PDCCH is configured to include a transport mode of one transport block, the terminal determines one PUCCH resource according to the control channel unit index of the PDCCH, and uses the determined one PUCCH resource as the PUCCH resource. A PUCCH resource corresponding to the response message on the above one transport block. When the downlink component carrier/cell is configured to include the transmission mode of the two transport blocks, the physical uplink control channel resources configured by the upper layer may be P or P pairs (2P total); when the downlink component carrier/cell is configured as one transmission In the transmission mode of the block, the physical uplink control channel resource configured by the upper layer may be P; wherein the value of P is preferably 4. Determining the PUCCH resource for transmitting the response message according to the PUCCH resource configured in the upper layer and the resource indicator ARI in the PDCCH includes the following cases:

1) When the above-mentioned monthly service cell is configured to include a transmission mode of two transport blocks, and the PUCCH resource configured by the upper layer is configured in pairs, the terminal determines a pair of PUCCH resources according to the ARI indication in the PDCCH, and the determined one is determined. The PUCCH resource is used as a PUCCH resource corresponding to the response message on the above two transport blocks;

2) When the foregoing serving cell is configured to include a transmission mode of two transport blocks, and the PUCCH resources configured by the upper layer are configured one by one, the terminal determines two PUCCH resources according to the ARI indication in the PDCCH, and the two PUCCHs to be determined are determined. The resource acts as a PUCCH resource corresponding to the response message on the above two transport blocks;

3) When the serving cell is configured to include a transmission mode of one transport block, the terminal determines a PUCCH resource corresponding to the response message on the one transport block according to the ARI indication in the PDCCH. Or determining, according to the high-level configured PUCCH resource and the resource indicator ARI in the PDCCH, the PUCCH resource that sends the response message may also include the following:

1) When the physical downlink control information DCI of the serving cell is represented as a format of two transport blocks, and the PUCCH resource configured by the upper layer is configured in pairs, the terminal determines a pair of PUCCH resources according to the ARI indication in the PDCCH, and determines a pair of PUCCH resources as PUCCH resources corresponding to the response messages on the above two transport blocks;

2) When the DCI of the serving cell is in the format of two transport blocks, and the PUCCH resources configured by the upper layer are configured one by one, the terminal determines two PUCCH resources according to the ARI indication in the PDCCH.

3) When the DCI of the serving cell is in the format of one transport block, and the PUCCH resource configured in the upper layer is configured in pairs, the terminal determines a pair of PUCCH resources according to the ARI indication in the PDCCH, and the determined pair of PUCCHs One PUCCH resource in the resource is used as a PUCCH resource corresponding to the response message on the above one transport block;

4) When the DCI or PDCCH of the serving cell is represented by a transport block format, and the PUCCH resource configured by the upper layer is configured by the eNB, the terminal determines the response message with the one transport block according to the ARI indication in the PDCCH. Corresponding PUCCH resources. Manner 2: When the terminal determines that the system type is the FDD or the TDD system, and the feedback mode is the channel selection mode, step S406 includes: determining a relationship between the number M of the response message and the configured number of PUCCHs. If M is less than or equal to N, Then, M PUCCHs are selected from the configured PUCCHs as PUCCH resources for transmitting a response message. Manner 3: When the terminal determines that the system type is the FDD system, and the feedback mode is the channel selection mode, step S406 includes: determining whether the current subframe receives only the scheduling of the primary serving cell (that is, only receiving the PDSCH from the primary serving cell); If yes, determining a PUCCH resource for transmitting a response message according to an implicit mapping relationship between the PUCCH resource and the physical downlink control channel PDCCH; for example: determining a PUCCH resource for transmitting a response message according to an index of a control channel unit of the PDCCH. For example, when the primary serving cell is configured to include the transmission mode of the two transport blocks, the terminal determines two PUCCH resources according to the control channel unit index of the PDCCH, and uses the determined two PUCCH resources as the response cancellation on the two transport blocks. The PUCCH resource corresponding to the information; when the primary serving cell is configured to include the transmission mode of one transport block, the terminal determines one PUCCH resource according to the control channel unit index of the PDCCH, and uses the determined one PUCCH resource as one transport block. The PUCCH resource corresponding to the response message. In this case, the terminal sending the response message by using the determined PUCCH resource includes: a manner in which the terminal agrees with the base station, determines a transmission format of the determination response message, and sends a response message by using the determined PUCCH resource and the determined transmission format. For example, the current subframe receives only the primary serving cell, and the terminal sends a response message in the manner of PUCCH format la or lb; or the response message sent by the terminal in the manner of channel selection. Specifically, when the terminal and the base station agree to send a response message in a manner that the terminal uses the PUCH format la or lb, when the primary serving cell is configured to include a transmission mode of two transport blocks, or when the DCI of the serving cell is represented as 2 When transmitting the format of the block, the terminal determines that the transmission format of the response message is PUCCH format la; when the primary serving cell is configured to include a transmission mode of one transport block, or when the DCI of the serving cell is expressed as a format of one transport block, the terminal The transmission format of the response message is determined to be PUCCH format lb. When the terminal and the base station agree to send a response message in a manner that the terminal uses the channel selection manner, and when the primary serving cell is configured to include the transmission mode of the two transport blocks, the terminal determines two PUCCH resources according to the control channel unit index of the PDCCH. And determining the 2 PUCCH resources as the PUCCH resources corresponding to the response messages on the foregoing two transport blocks; when the terminal and the base station agree on the manner that the terminal uses the channel selection manner to send the response message and when the primary serving cell is configured to include In the transmission mode of one transport block, the terminal determines one PUCCH resource according to the control channel element index of the PDCCH, and uses the determined one PUCCH resource as the PUCCH resource corresponding to the response message on the one transport block. When the terminal and the base station agree to send a response message in a manner that the terminal uses the PUCCH format la/lb, the terminal determines a PUCCH transmission response message according to the control channel unit index of the PDCCH. Manner 4: When the terminal determines that the system type is a TDD system, and the feedback mode is the channel selection mode, step S406 includes: Determining whether carrier/inter-cell binding is required according to the number of bits of the response message; if binding is not required, determining whether the corresponding PDCCH of the serving cell is sent on the primary serving cell; if yes, multiple downlinks corresponding to the uplink subframe The resource of the response message on the frame is determined according to an implicit mapping relationship with the PDCCH of the multiple downlink subframes; for example, determining the PUCCH resource of the response message according to the index of the control channel unit of the PDCCH of the multiple downlink subframes; The resource of the response message on the multiple downlink subframes corresponding to the uplink subframe is determined according to the PUCCH resource configured by the upper layer and the resource indicator ARI in the PDCCH of the multiple downlink subframes; for example:

1) The high-level configured PUCCH resource is the uplink determined by the ARI in the PDCCH of the multiple downlink subframes when the base station is the P resources configured for each non-primary downlink component carrier or the non-primary downlink component cell in each downlink subframe. a PUCCH resource in a plurality of downlink subframes corresponding to the subframe, where the ARIs in the PDCCHs of the multiple downlink subframes are the same or different;

2) The PUCCH resource configured in the upper layer is the P subframe resource configured by the base station for each non-primary downlink component carrier or the non-primary downlink component cell, and is determined according to the uplink subframe determined by the ARI in the PDCCH of the multiple downlink subframes. A PUCCH resource on multiple downlink subframes, where ARIs in PDCCHs of multiple downlink subframes are different. If it is determined that the carrier/cell binding needs to be performed according to the number of bits of the response message, the step S406 includes: binding the response message according to the carrier or the cell binding manner; and the binding response message includes the primary serving cell. The response message, or when the PDCCH corresponding to the ACK message after the binding includes the PDCCH on the primary downlink component carrier/cell, the PDCCH is determined according to the implicit mapping relationship of the PDCCH of the primary downlink component carrier. The PUCCH resource corresponding to the message; for example, the index of the control channel unit of the PDCCH of the primary downlink component carrier; the response message after the binding does not include the response message of the primary serving cell, and the response message corresponding to the binding When the PDCCH is not transmitted on the primary cell, the PUCCH resource configured in the upper layer and the resource indicator ARI in the PDCCH of the pre-determined monthly traffic cell determine the PUCCH corresponding to the combined response message. Resources. For example, when the high-level configured PUCCH is the base station for each of the four resources that are not included in the primary serving cell and the PDCCH is not in the primary monthly serving cell, the resources are in the PDCCH. The indicator ARI determines the PUCCH resource corresponding to the ACK message after the binding, where the resource indicator ARI of the PDCCH of the pre-determined serving cell is the same or different in the multiple downlink subframes; when the PUCCH configured by the upper layer is the base station For each of the four resources that do not include the primary serving cell and the PDCCH is not configured in the binding of the primary server, the resource corresponding to the binding indicator in the PDCCH is determined according to the resource indicator ARI in the PDCCH. The PUCCH resource, where the resource indicator ARI of the PDCCH of the pre-determined monthly traffic cell is different in the plurality of downlink subframes. Manner 5: When the terminal determines that the system type is a TDD system, and the feedback mode is PUCCH format 3, step S406 includes: determining a PUCCH resource for sending a response message according to the PUCCH resource configured by the high layer, and according to the ARI in the PDCCH on the non-serving cell. . For example, the high-level configured PUCCH resource is a plurality of PUCCH resources corresponding to the PUCCH format 3 configured by the base station, and the ARIs in the PDCCHs of the multiple downlink subframes indicate multiple PUCCH resources, where the ARI has the same value in multiple subframes. The PUCCH resource that sends the response message is determined according to the ARI in the PDCCH on the non-serving cell. Manner 6: When the terminal determines that the system type is the TDD system, if the terminal only receives the scheduling of the primary month cell in the current subframe, the terminal determines the transport block of the primary serving cell in the multiple downlink subframes corresponding to the specified uplink subframe. The feedback mode of the response message is the channel selection mode. In this case, the step S406 includes: the terminal determines the PUCCH resource for sending the response message according to the implicit mapping relationship between the PUCCH resource and the PDCCH of the multiple downlink subframes. For example: The index of the control channel unit of the PDCCH of the plurality of downlink subframes of the terminal determines the PUCCH resource of the transmission response message. The present embodiment determines the used PUCCH resource by considering the system in which the terminal is located and the feedback manner of the terminal feedback response message, and uses the determined PUCCH resource to send a response message, thereby solving the problem that the UE cannot complete the response message transmission in some cases, and improves the system.
