detailed description

In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

In order to introduce the embodiment of the present invention clearly and in detail, the related technologies of the embodiment of the present invention are firstly introduced here. 3GPP LTE-ARel-10/11 is an enhancement of LTErel-8/9 technology. In order to meet the requirements of LTE-A, the LTE-A system uses Carrier Aggregation (CA) technology as a method to expand the system bandwidth, and adopts a large number of Multiple Input Output (Multiple Input Multiple Output, MIMO for short) enhancement technology and adaptive technology improve data rate and system performance. In an LTE-ARel-10 carrier aggregation scenario, one user equipment (User Equipment, referred to as UE) can support up to 5 CCs. In the LTE-A system, the UE needs to feed back CSI to the eNB, where the CSI includes a Channel Quality Indicator (CQI for short), a Precoding Matrix Indicator (PMI for short), and a Rank Indicator (RI for short). The base station determines the Modulation and Coding Scheme (MCS for short) used in the downlink according to the received feedback information, and implements Adaptive Modulation and Coding (AMC for short), that is, dynamically selects an appropriate modulation and coding scheme according to changes in channel conditions.

In the LTE-A system, CSI reporting includes triggered and periodic reporting. Triggered reporting is also called aperiodic reporting, and aperiodic CSI is a supplement to periodic CSI. Periodic CSI reporting mainly includes two types: broadband reporting mode and frequency selection reporting mode. As shown in Figure 2, the broadband reporting mode only feeds back wideband (Wideband, referred to as WB) CSI, and the frequency selection reporting mode feeds back both wideband CSI and subband (Subband, referred to as SB) CSI. In Figure 2, WB represents wideband CSI. SB denotes subband CSI. N _p is the reporting period, and its value for Frequency Divided Duplex (FDD for short) is shown in Table 1.

Table 1

The base station notifies the UE of the parameter I _CQI/PMI through radio resource control (RadioResourceControl, referred to as RRC) layer signaling, and the UE finds the corresponding value of N _p according to the interval of the parameter in Table 1, and calculates the subframe offset N _offset , and then determine the subframe for reporting CSI according to the reporting period and subframe offset, and the specific reporting content is determined by the reporting mode. For different modes, the period of the broadband reporting mode is N _p , and the reporting period of the broadband CSI in the frequency selection reporting mode is H*N _p , where H=J*K+1. In the frequency selection periodic CQI reporting mode, the entire broadband is divided into J partial bandwidths (BandwidthPart, referred to as BP), each BP includes multiple subbands (Subband, referred to as SB), and an optimal subband is selected in each BP (BestSB) for reporting, and K represents the number of sub-band reporting cycles.

Take Figure 2 as an example, J=3, K=2, that is, there are 3 optimal sub-band reports for BP, the sub-band report cycles twice, and one reporting cycle (Reporting Cycle, RC for short) is: WB-SB1-SB2 -SB3-SB1-SB2-SB3. Among them, WB means to report wideband CQI or wideband CQI plus wideband PMI, which is determined by RI. If RI=1, WB means wideband CQI; if RI>1, WB means wideband CQI plus wideband PMI. The CQI corresponding to the best SB. It can be seen that the duration of one RC is equal to the reporting period of the broadband CSI. If there is wideband PMI that needs to be fed back, it can be fed back together with the wideband CQI in the reporting subframe of the wideband CQI.

Rel-10 supports 6 standard bandwidths: 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20MHz. The CCs used for carrier aggregation in Rel-10 are all backward-compatible carriers that can exist independently. From the perspective of a single carrier, they are the same as Rel-8/9 and can be used by Rel-8/9 users. Some non-backward compatible carriers may be supported in Rel-11, which may be standard bandwidth or non-standard bandwidth. These ExtendedCCs and SegmentCCs introduced in Rel-11 may have no synchronization signals, including primary synchronization signals and secondary synchronization signals, no system messages, no paging messages, no uplink/downlink control channels, and may only be used to transmit data and pilots The pilot frequency includes a listening reference signal (SoundingReferenceSignal, referred to as SRS), a demodulation reference signal (DemodulationReferenceSignal, referred to as DMRS), a common reference signal (CommonReferenceSignal, referred to as CRS) or a channel state information reference signal (ChannelStateInformation-ReferenceSignal, referred to as CSI- RS), if there is a CRS, there may be no CSI-RS, and if there is no CRS, the CSI-RS may be used for CSI measurement.

In the process of implementing the present invention, the inventors found that: for non-backward compatible extended carriers such as ExtendedCC and SegmentCC introduced in Rel-11, how to report the periodic CSI is a problem that needs to be solved. Since the UE may have multiple groups of independent carriers, and these independent carriers have independent reporting subframes, there is a certain probability that periodic CSI of two or more independent carriers may be reported in one subframe, resulting in a collision. If the extended carrier also has an independent reporting subframe, the probability of collision will inevitably increase, and because the priority of the extended carrier is low, the probability of being discarded is high. In the embodiment of the present invention, by inserting the CSI of the extended carrier into the periodic CSI reporting subframe of the attached independent carrier, the CSI of the extended carrier can be reported periodically, and the probability of reporting conflicts and CSI of the extended carrier being discarded is reduced. Specifically, the embodiment of the present invention can be implemented by using the process shown in FIG. 3 .

FIG. 3 is a schematic flowchart of Embodiment 1 of an information reporting method provided by an embodiment of the present invention. As shown in Figure 3, this embodiment includes:

Step 301: Generate report information according to the first CSI of the extended carrier and the second CSI of the independent carrier, the extended carrier is attached to the independent carrier;

In this step, the report information generated according to the first CSI of the extended carrier and the second CSI of the independent carrier may include the first CSI and the total CSI, or the second CSI and the total CSI, or the first CSI, The second CSI and the total CSI, or include the first CSI and the second CSI.

The extended carrier here refers to the non-backward compatible carrier introduced in 3GPP LTE-ARel-11 and later versions, including ExtendedCC, SegmentCC and so on. The independent carrier here refers to the carrier that can exist independently introduced by 3GPP LTE-ARel-11 and its previous versions. The first CSI here includes the first wideband CSI of the extended carrier and/or the first subband CSI of the extended carrier, and the second CSI includes the second wideband CSI of the independent carrier and/or the first subband CSI of the independent carrier The second sub-band CSI. Wherein the first/second wideband CSI includes the first/second wideband CQI, and optionally also includes the first/second wideband PMI; the first/second subband CSI includes but is not limited to the respective best subband CQI and Optimal subband position. This embodiment does not limit the specific content of the first CSI and the second CSI. In addition, the attachment relationship between the extended carrier and the independent carrier can be determined by methods in the prior art, for example, according to the notification when the base station configures the extended carrier, the center frequency is determined nearby, the main carrier is attached by default, etc., and the attachment relationship can be determined through signaling Changes, which are not limited in this embodiment.

Step 302. Send the report information in the report subframe of the independent carrier.

In an application, the reporting information is generally generated according to the first CSI of all extended carriers attached to the independent carrier and the second CSI of the independent carrier. It is equivalent to sending the CSI of the independent carrier and all extended carriers attached to the independent carrier in the reporting subframe of the independent carrier.

The embodiment of the present invention adopts the technical means of generating reporting information according to the CSI of the extended carrier and the CSI of the independent carrier, and sending the reporting information in the reporting subframe of the independent carrier, which can realize periodic CSI reporting of the extended carrier.

FIG. 4 is a schematic flowchart of Embodiment 2 of an information reporting method provided by an embodiment of the present invention. As shown in Figure 4, this embodiment includes:

Step 401, generating the first CSI of the extended carrier and the second CSI of the independent carrier;

The extended carrier here is attached to the independent carrier. The generation here may be based on the periodic reporting mode of the independent carrier, or may be generated according to a preset reporting rule, which is not limited in this embodiment.

The periodic reporting mode of the independent carrier includes a mode type. Specifically, the mode types include broadband reporting mode and frequency selection reporting mode as shown in FIG. 2 . If the mode type is the frequency selection reporting mode, the periodic reporting mode also includes parameters such as the number of sub-band reporting cycles, the granularity of BPs, that is, how many SBs each BP contains, and the like. For example, generating the first CSI and the second CSI according to the periodic reporting mode of the independent carrier may specifically be: if the mode type is a broadband reporting mode, generating the second wideband CSI including the independent carrier The second CSI includes the first CSI of the first wideband CSI of the extended carrier; if the mode type is frequency selective reporting mode, generate the second wideband CSI and the second sub-band CSI including the independent carrier The second CSI with CSI includes the first wideband CSI of the extension carrier and the first CSI of the first subband CSI.

Optionally, in step 401, the first CSI and the second CSI may also be generated according to a preset reporting rule. For example, generating second CSI including second wideband CSI, first CSI including first wideband CSI and first subband CSI; or generating second CSI including second wideband CSI and second subband CSI, The first CSI including the first wideband CSI or the first subband CSI; etc., which are not limited in this embodiment. It should be noted that if the first CSI does not include the first sub-band CSI, signaling overhead can be saved; if the first CSI includes the first sub-band CSI, system throughput can be improved; the second CSI includes or does not include Including the second sub-band CSI is also similar.

In addition, the UE can obtain the above-mentioned first wideband CSI, first subband CSI, second wideband CSI, and second subband CSI according to methods in the prior art, such as obtaining wideband CQI and subband CQI through CRS or CSI-RS measurement and through The wideband PMI is obtained by searching the codebook, which is not limited in this embodiment.

Specifically, if it is determined that the first CSI includes the first subband CSI of the extended carrier, the first subband CSI may be obtained in the following manner: select at least one optimal subband in the extended carrier, and set The CSI of the at least one optimal subband is used as the first subband CSI; or, the extended carrier is divided into at least one BP, and an optimal subband is selected in each BP of the at least one BP band, at least one optimal sub-band is obtained, and the CSI of the at least one optimal sub-band is used as the first sub-band CSI; this embodiment does not limit it. Preferably, the BP granularity of the extended carrier is not smaller than the BP granularity of the independent carrier, so that the best MCS can be obtained without increasing the proportion of signaling overhead, and the system throughput can be improved. Optionally, the extended carrier is divided into multiple BPs according to the BP granularity of the independent carrier.

Step 402, generating the total CSI of the joint frequency domain of the extended carrier and the independent carrier;

For example, if the extended carrier includes a 10M bandwidth with a center frequency of 800MHz, and the independent carrier includes a 10M bandwidth with a center frequency of 900MHz, then the joint frequency domain is obtained by performing carrier aggregation on a 10M bandwidth of 800MHZ and a 10M bandwidth of 900MHZ. 20M bandwidth for a UE. Therefore, the total CSI of the joint frequency domain of multiple carriers is the CSI of the bandwidth formed after the multiple carriers are aggregated. The total CSI here can be obtained, but not limited to, in the following ways: First, the signal-to-interference-plus-noise ratio (Signal to Interference plus Noise Ratio, referred to as SINR) of the extended carrier and the independent carrier is measured by CRS or CSI-RS respectively, and then according to the extended carrier and the independent carrier The SINR obtains the full-bandwidth average SINR on the joint frequency domain of the extended carrier and the independent carrier, and obtains the total CQI according to the full-bandwidth average SINR; the total PMI can be obtained in a similar way to determine the broadband PMI of the independent carrier in the prior art, for example, by searching The codebook is obtained. If there are multiple extended carriers attached to the independent carrier, the total CSI is CSI in the joint frequency domain of the multiple extended carriers and the independent carrier.

Step 403: Generate report information, where the report information includes the first CSI and total CSI, or the second CSI and total CSI, or the first CSI, second CSI and total CSI;

The reported information here generally includes the first CSI, and optionally includes the second CSI and/or total CSI. The positions of the first CSI, the second CSI, and the total CSI in the reported information may be arranged in any order, which is not limited in this embodiment. It should be noted that step 402 is optional, if step 402 is not performed, then in step 403, report information is generated according to the first CSI and the second CSI.

If it is determined in step 401 that the first CSI includes the first sub-band CSI and the second CSI includes the second sub-band CSI, then step 403 specifically includes: determining the second sub-band CSI according to the periodic reporting mode of the independent carrier The reporting information is generated according to the rule that the subband reporting cycle times of the first subband CSI is not greater than the subband reporting cycle times of the second subband CSI.

In addition, the position sequence of each CSI in the reported information is related to the accuracy of the actually used CSI. For example, when the base station wants to use the second CSI of an independent carrier, it will search for the second CSI with the closest time in the received reported information. Historical value, if the second CSI is placed behind the first CSI in the current report information, and at this time the base station has only received the first CSI in the current report information but has not received the second CSI, it needs to search for the last received CSI The historical value of the second CSI in the reported information, and if the actual value of the second CSI has changed in the two adjacent reported information, then the second CSI found by the base station from the last reported information The historical value of is not consistent with the actual value, thus affecting the selection of the base station for the MCS. Therefore, the position of each CSI in the reported information can be set according to the actual application situation.

Further, step 403 specifically includes: the number of sub-band reporting cycles of the first sub-band CSI is t, the number of sub-band reporting cycles of the second sub-band CSI is k, k and t are positive integers, if t< k, according to the rule that the first sub-band CSI and the second sub-band CSI are included in the last t times of the sub-band reporting cycles k times of the second sub-band CSI, or, in the second sub-band CSI The rule of the first sub-band CSI and the second sub-band CSI is contained in the first t times of the sub-band reporting cycle k times with CSI, and the reporting information is generated. It is equivalent to placing the first subband CSI in the first or last subband cycles in the reported information.

Optionally, step 403 specifically includes: if the reported information includes the first CSI and the second CSI, according to the rule that the second CSI precedes the first CSI, that is, the second CSI It is listed before the first CSI in the report information. Alternatively, the reporting information is generated according to a rule of arranging the first CSI and the second CSI in the order of the frequency domain positions of the extended carrier and the frequency domain positions of the independent carrier. For example, if arranged according to frequency domain positions, assuming that the first CSI is located before the second CSI in the frequency domain, the position of the first CSI in the report information is located before the second CSI.

Step 404, sending the report information in the report subframe of the independent carrier;

Specifically, the reporting subframe of the independent carrier is determined according to the reporting period and the subframe offset of the independent carrier, and the reporting information is sent in the reporting subframe. Here, the reporting information may be used as the reporting content of a reporting cycle.

Step 405, if the extended carrier is deactivated or changed, or at least one new extended carrier is activated or changed and the activated or changed at least one new extended carrier is attached to the independent carrier, then the Report information for adjustment.

The change here usually refers to the change of the attachment relationship. For example, if the extended carrier is changed from being attached to the independent carrier A to being attached to the independent carrier B, the periodic CSI of the extended carrier is changed from being reported together with the periodic CSI of the independent carrier A to being reported with the independent carrier A. The periodic CSI of independent carrier B is reported together, which will affect the reported information in the reporting subframes of independent carrier A and independent carrier B, and the reported information needs to be updated, that is, the adjustment is performed. When there are multiple extended carriers attached to the independent carrier, if at least one of the multiple extended carriers is deactivated or changed, or at least one new extended carrier is activated or changed and all activated or changed The at least one new extended carrier is attached to the independent carrier to update the total CSI and the first CSI, so as to adjust the reported information. In other words, any change in the set of carriers attached to the independent carrier may affect the reporting information in the independent carrier reporting subframe, and such impact will be reflected in the next reporting round. The change signaling can be notified by the base station to the UE through a MACCE message, or notified by the base station to the UE through radio resource control (RadioResourceControl, RRC) layer signaling, or notified to the UE by the base station through physical layer signaling. This is not limited.

Generally, the carrier deactivation and activation signaling is notified by the base station to the UE through the Medium Access Control (MAC) control unit CE message. After the UE receives the deactivation and activation signaling, the carrier deactivation and activation process can be performed according to the existing Technical approach to processing. It should be noted that when receiving the deactivation signaling of the independent carrier, the UE deactivates both the independent carrier and the extended carrier attached to the independent carrier, and the deactivated independent carrier and its extended carriers do not need to perform periodic CSI reporting.

In the embodiment of the present invention, the first CSI of the extended carrier and the second CSI of the independent carrier are generated according to the periodic reporting mode of the independent carrier or the preset reporting rule, and the joint frequency domain of the extended carrier and the independent carrier is generated. The total CSI generates reporting information according to the first CSI, the second CSI, and the total CSI, and the reporting information in the reporting subframe of the independent carrier can implement periodic CSI reporting of the extended carrier. Furthermore, the sequence of CSIs in the reported information can also be set according to actual application conditions, so as to improve the accuracy of use.

In practical applications, the embodiments of the present invention may have various application forms, including but not limited to the following ten forms. The content of the reporting information sent by the embodiment of the present invention will be introduced below based on each application.

It should be noted that in this application, the relative positions of Extended/SegmentCC and AttachedCC are unified for wideband CSI and optimal subband CSI, either AttachedCC is in front, or in a certain order, such as from low frequency to high frequency.

For WBall in the third, fifth, and sixth applications, since the CQI of AttachedCC is obtained through CRS measurement, and there may be no CRS on Extended/SegmentCC, the CQI of Extended/SegmentCC may be obtained through CSI-RS measurement, so according to CRS measurement There is a certain accuracy difference between the obtained CQI and the CQI obtained according to the CSI-RS, and there will also be an error of one degree when calculating the WBall. In addition, only the CSI of the activated CC is reported in the RC, so when a carrier is activated, the broadband change or subband increase brought by the CSI corresponding to the carrier is reflected in the RC; when a CC is deactivated, the impact of the CC Eliminated from round robin. For the fourth application, the CQI measurement range of WBall will change with the activation and deactivation of CC. When a CC is activated, the bandwidth used to measure WBall wideband CQI becomes larger. When a CC is deactivated , the bandwidth used to measure the WBall wideband CQI becomes smaller. For example, if an Extended/SegmentCC attached to the AttachedCC is activated and then deactivated, the three consecutive RCs may be:

RC1: WB-SB1-SB2-SB3-SB1-SB2-SB3

RC2: WBall-SB1-SB2-SB3-SB1-SB2-SB3

RC3: WB-SB1-SB2-SB3-SB1-SB2-SB3

For example, if an Extended/SegmentCC attached to the AttachedCC is activated and then deactivated, the three consecutive RCs may be:

RC1: WB-SB1-SB2-SB3-SB1-SB2-SB3

RC2: WB-SB1-SB2-SB3-SB4-SB1-SB2-SB3-SB4

FIG. 6 is a schematic flowchart of Embodiment 1 of an information processing method provided by an embodiment of the present invention. As shown in Figure 6, this embodiment includes:

Step 601: Receive the report information sent by the UE, the report information includes the CSI related to the extended carrier, and the extended carrier is attached to an independent carrier;

For example, the base station device receives the report information sent by the UE. Here, the CSI related to the extended carrier may be the CSI of the extended carrier, or the CSI of the independent carrier to which the extended carrier is attached, or the total CSI of the combined frequency domain of the extended carrier and the independent carrier. Not limited.

Step 602. Determine the MCS of the extended carrier according to the CSI related to the extended carrier.

Here, according to the content of the reported information, the method of determining the MCS of the extended carrier is also different. For example, the channel state information CSI related to the extended carrier is the first CSI of the extended carrier, and the MCS of the extended carrier can be determined according to the first CSI. Determine the MCS of the extension carrier, which is not limited in this embodiment.

In the embodiment of the present invention, by receiving the report information sent by the UE, and determining the MCS of the extension carrier according to the CSI related to the extension carrier in the report information, adaptive modulation and coding of the extension carrier can be realized.

FIG. 7 is a schematic flowchart of Embodiment 2 of an information processing method provided by an embodiment of the present invention. As shown in Figure 7, this embodiment includes:

Step 701, receiving the reporting information sent by the UE;

Step 702, judging whether the reported information includes the first CSI of the extended carrier, if so, execute step 703, if not, execute step 704;

The first CSI here includes the first wideband CSI and/or the first subband CSI of the extension carrier.

Step 703: Determine the MCS of the extended carrier according to the first CSI.

If the first CSI includes the first subband CSI, and the first subband CSI includes the CQI of the best subband and its position, then the CQI of the best subband can be used to determine the MCS of the best subband, For other subbands of the extended carrier other than the optimal subband, since the reported information does not include the CQI and position of the other subbands, the first wideband CSI containing the first wideband CQI is used to determine the other subbands. If the first CSI does not include the first wideband CSI, the MCS of the best subband can also be used as the MCS of other subbands; if the first CSI includes the first wideband CSI, it can also be based on the first CSI The first wideband CQI contained in a wideband CSI determines the MCS of the extended carrier, and the MSC is applicable to all subbands of the extended carrier.

Step 704, judging whether the reported information contains total CSI, if so, execute step 705, otherwise execute step 706;

The total CSI here is the CSI of the joint frequency domain of the extended carrier and the independent carrier to which the extended carrier is attached. It should be noted that, in this embodiment, there is no limitation to the case where the reported information does not include the first CSI, the second CSI and the total CSI at the same time. Step 706 is to include the second CSI in the reported information, but not include the first CSI and treatment of total CSI cases.

Step 705: Determine the MCS of the extended carrier according to the total CSI.

Since the total CSI covers the bandwidth of the extended carrier, the MCS of the extended carrier can be determined according to the total CSI, and this MCS is applicable to all subbands of the extended carrier.

Step 706: If the reported information includes the second CSI of the independent carrier to which the extended carrier is attached, determine the CSI offset of the extended carrier relative to the independent carrier;

For example, the CSI offset may be determined according to the frequency domain position of the extended carrier and the frequency domain position of the independent carrier, and the CSI offset may be calculated by the base station equipment, or may be notified by the UE to the base station equipment , which is not limited in this embodiment.

Step 707: Determine the first CSI of the extended carrier according to the CSI offset and the second CSI;

Step 708: Determine the MCS of the extended carrier according to the first CSI.

For example, for SegmentCC, since the SegmentCC is adjacent to the attached independent carrier, the corresponding CSI offset can be set to 0, that is, the second wideband CQI of the independent carrier is directly used as the first wideband CQI of the extended carrier, Then determine the MCS of the extended carrier according to the first wideband CQI. This embodiment does not limit it.

In addition, it should be noted that in order to maximize the applicability of the final MCS and extended carrier, in the above steps, first determine whether the reported information contains the first CSI, so the MCS determined according to the first CSI in the reported information may be the most suitable . However, in practical applications, even if the reported information includes the first CSI, the MCS of the extended carrier may be determined according to the total CSI or the second CSI in the reported information, which is not limited in this embodiment.

In the embodiment of the present invention, by receiving the report information sent by the UE, and determining the MCS of the extension carrier according to the CSI related to the extension carrier in the report information, adaptive modulation and coding of the extension carrier can be realized. Further, even if the first CSI of the extended carrier is not included in the reported information, the embodiment of the present invention can also determine the extended The MCS of the carrier expands the scope of application, and is also applicable to the environment where the UE does not periodically report the CSI of the extended carrier.
