Description

TECHNICAL FIELD

[0001] The present document relates to, but is not limited to, wireless communication technology, in particular to a method and apparatus for information feedback, a method and apparatus for information receiving. BACKGROUND

[0002] High frequency communication is one of the core technologies of New Radio (NR), which can provide ultra-large bandwidth communication for future communication and greatly improve communication capacity. One important feature of high frequency communication is based on beam transmission, especially radio frequency beam transmission. Because the path loss of high frequency signal is relatively large, it is necessary to improve the coverage distance based on beam gain. On the other hand, the wavelength of high frequency is relatively short, which can form a large-scale antenna array and also provides the possibility for beam-based communication.

[0003] Based on the beam communication system, the sending beam and receiving beam pair need to be aligned before communication. Moreover, due to the partial coverage of the beam, the communication between the two parties may be blocked by obstacles or other factors, such as the movement of the terminal. In order to quickly recover from the failed beam pair and consider the multi-user scheduling of the base station, the terminal needs to feed back multiple sending beams to the base station.

[0004] NR determines that the terminal can feed back 4 beams at a time in 64 sending beams. Considering that each sending beam also needs to feed back the reference signal receiving power (RSRP), the feedback overhead will be relatively large. In addition, considering that more beams may need to be fed back in more sending beams in future standard versions, and the quality information of each beam needs to be fed back, it is necessary to consider how to reduce the feedback overhead of multi-beam feedback. At present, there is no solution to reduce the feedback overhead of multi-beam feedback. SUMMARY

[0295] The embodiment of the present disclosure is described in detail below through application examples, and the application examples are only used to state the present disclosure and do not limit the protection scope of the present disclosure.

[0296] Application Example 1

[0297] In the present application example, the base station instructs the terminal to report at most M_max measurement reference signal resources in L measurement reference signal resources to the base station; or, the base station and the terminal agree that the terminal can report at most M_max measurement reference signal resources in L measurement reference signal resources to the base station. The terminal may, according to actual measurement conditions, only report M quality indication information corresponding to M measurement reference signal resource indication information and M measurement reference signals; or, the terminal may, according to actual measurement conditions, only report Q quality indication information corresponding to (Q) measurement reference signal resource indication information and Q measurement reference signals; wherein, M and Q are integers less than or equal to M_max. Since M and Q are allowed to be less than M_max, the terminal needs to feed back the information of M and Q to the base station. For this purpose, the following methods can be used:

[0298] Method 1: There is a bit field in the feedback information of the terminal, and the bit field is used to indicate the value of M and / or Q; for example, the information field fed back by the terminal is as follows: [M value (occupies bits), M resource indication information, Q value bits), Q quality indication information], and optionally, when it is agreed that M and Q are always the same, only the value of M needs to be fed back, that is, the feedback information is (M value (occupies bits), M resource indication information, M quality indication information).

[0299] Optionally, the number of bits occupied by the M resource indication information can be determined according to the value of M; for example, the number of bits occupied by the M resource indication information is bits. Since the base station does not know the actual value of M selected by the terminal, the terminal is allocated feedback resources according to When M is less than M_max, if is less than , the bits can be repeated to form bits; for example, if is 3 bits and is 8 bits, the bits are repeated 3 times, and the last bit of the last repetition is discarded; wherein the M resources are selected from the L resources.

[0300] Method two: the terminal uses a first specified value to indicate the end symbol of the M resource indication information in the feedback information, and / or uses a second specified value to indicate the end symbol of the Q quality indication information in the feedback information; for example, the information fed back by the terminal is (M resource indication information, end symbol of resource indication information, Q quality indication information, end symbol of quality indication information); optionally, the number of bits occupied by each resource indication information in the M resource indication information is the same as the number of bits occupied by the end symbol of the resource indication information; for example, each resource indication information is represented by bits, and the end symbol of the resource indication information is also represented by bits; for example, the end symbol of the resource indication information is represented by L+y; wherein y is a non-negative integer, i.e. the end symbol of the M resource indication information is represented by L; for example, L=7, M=2, the terminal uses 2 resource indication information of 2 resources selected by 2 3-bit feedbacks, and then uses 3 bits with a value of 7 to indicate the end of the M resource indication information, i.e. the last bit of the M resource indication information is always followed by an end symbol of the resource indication information.

[0301]

[0302] Table 1

[0303] Index value Quality value (RSRP) 0 -140 dBm 1 -139 dBm … … 96 -44 dBm 97 End of quality information

[0304] Table 2

[0305] Optionally, the number of bits occupied by each quality indication information in the Q quality indication information is the same as the number of bits occupied by the end symbol of the quality indication information; for example, each quality indication information is represented by bits, and the end symbol of the quality indication information also occupies P is the number of index values included in the mapping table between the index values and the quality values referred to by the quality indication information; for example, the mapping table between the index values and the quality values is shown in Table 1 (Table 1 takes the reference signal received power (RSRP) as an example); wherein P = 97. Alternatively, the end symbol of the quality indication information is represented by the index P value, i.e. the end symbol of the resource indication information is represented by the P+z value, z is a non-negative integer. That is, the table shown in Table 2 is established, i.e. the quality indication information end symbol and the quality indication information are jointly coded at this time. That is, the mapping table between the index values and the quality values referred to by the quality indication information includes a specific mapping item, and the index value in the specific mapping item represents the end symbol of the Q resource indication information. When the predetermined M and Q are equal, the quality indication information end symbol in Table 2 can also represent the resource indication information end symbol.

[0306] Method three: the terminal feeds back M resource indication information, and the base station blindly detects different M values; for example, since the base station does not know the actual feedback resource number of the terminal, the resource is allocated according to the maximum M_max, and the terminal determines the number of bits required by the M resource indication information according to the actual feedback M value. When M is less than M_max, the number of bits occupied by the M resource indication information is less than the number of bits occupied by the M_max resource indication information, and then the terminal feeds back according to the number of bits occupied by the M resource indication information. Since there is CRC protection, the base station can know the M value selected by the terminal through blind detection. Similarly, the terminal feeds back Q quality indication information, and the base station blindly detects the Q value selected by the terminal. That is, the M and Q values are not fed back in the feedback information of the terminal, the base station obtains the M value through blind detection of the M resource indication information, and / or obtains the Q value through blind detection of the Q quality indication information, or obtains the combination value of M and Q through blind detection of the M resource indication information and the Q quality indication information. That is, the feedback information of the terminal can only occupy part of the feedback resource allocated by the base station. The feedback resource can be a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), etc. Alternatively, at this time, the number of bits occupied by the M resource indication information corresponding to different M values is different, and the number of bits occupied by the Q quality indication information corresponding to different Q values is different.

[0307] The fourth mode: the terminal feeds back the M value by repeating the bits. For example, since the base station does not know the actual feedback resource number of the terminal, the maximum M_max resource is allocated, and the terminal determines the number of bits required for the M resource indication information according to the actual feedback M value. When M is less than M_max, the number of bits occupied by the M resource indication information is less than the number of bits occupied by the M_max resource indication information. At this time, the terminal expands the number of bits occupied by the M resource indication information to the number of bits occupied by the M_max resource indication information by repeating the bits. For example, the number of bits occupied by the M_max resource indication information is 12, and when the number of bits occupied by the M resource indication information is 6, the M resource indication information can be repeated twice to form 12 bits. Optionally, the number of bits occupied at this time is the number of bits after channel coding (in the previous description, the number of bits occupied can be the number of bits before channel coding or the number of bits after channel coding). That is, each repeated segment of the M resource indication information is protected by the CRC check code. That is, the feedback information of the terminal occupies all the feedback resources allocated by the base station, and the coverage performance is improved to a certain extent by repeating.

[0308] The fifth mode: Q quality indication information is fed back. When the quality indication information is lower than a predetermined threshold, the resource indication information corresponding to the quality indication information is not fed back. For example, only 3 of the Q quality information are higher than the predetermined value, and 3 resource indication information is fed back in the resource indication domain value, that is, M=3, and the Q quality indication information is in front of the M resource indication information.

[0309] Optionally, the M is the minimum value between M_max and M1, wherein M1 is the number of resources in the L measurement reference signal resources that satisfy the first predetermined characteristic, and the first predetermined characteristic satisfies at least one of the following characteristics: the M1 resources are resources whose quality values in the L qualities corresponding to the L candidate resources are greater than a predetermined threshold; the M1 resources are resources whose correlations between the L candidate resources and a predetermined resource are less than a predetermined threshold; the M1 resources are resources whose differences from a predetermined quality in the L qualities corresponding to the L candidate resources are greater than a predetermined threshold, and M1 is a non-negative number.

[0310] Optionally, the Q is a minimum value between M_max and Q1, where Q1 is a number of quality information satisfying a second predetermined characteristic from L quality information corresponding to L measurement reference signal resource, the second predetermined characteristic satisfies at least one of the following characteristics: the quality corresponding to Q1 quality indication information is a quality from L quality corresponding to L candidate resource, and the quality value is greater than a fourth predetermined threshold; the quality corresponding to Q1 quality indication information is a quality from L quality corresponding to L candidate resource, and the correlation between the quality and a quality of a predetermined resource is less than a fifth predetermined threshold; the quality corresponding to Q1 quality indication information is a quality from L quality corresponding to L candidate resource, and the difference from a second predetermined quality is greater than a sixth predetermined threshold.

[0311] Similarly, the L measurement reference signal resources can also be L synchronization signals.

[0312] Application Example 2

[0313] In this application example, the base station allocates L measurement reference signal resources to the terminal, and instructs the terminal to select C resources from the L measurement reference signal resources. The terminal needs to feed back resource indication information of the selected C resources and C quality indication information corresponding to the C resources to the base station. The optimal value (such as the maximum value) in the C quality indication information is fed back in an absolute value manner, and the remaining quality indication information in the C quality indication information is fed back in a differential manner, and the reference quality of the differential quality feedback is the optimal quality in the C quality indication information.

[0314] The indication information of the C resources indicates the index information of the selected C resources in the L measurement reference signal resources configured by the base station. Optionally, the L measurement reference signal resources are channel state information reference symbols (CSI-RS) resources, and the resource indication information is CRI (CSI-RS resource indicator).

[0315] In order to save bits, the C resource indication information is represented by bits;

[0316] The C resource indication information is represented by bits;

[0317] Wherein, represents the number of different combinations of C-i resources when C-i resources are selected from L-b i resources, represents rounding up, the C resources are selected from a predetermined L candidate resource, the L is a positive integer greater than or equal to C, b i is the index information of the i-th resource in the C resources in the L candidate resources, and b i<b i+1 , 1≤b i ≤L.

[0318] Although using a combination approach is better than using each resource individually... The bit-based feedback method saves feedback overhead, but the combined feedback method above requires satisfying b. i <b i+1 Therefore, the quality of the first CRI (Critical Resource Indicator) reported may not be the highest quality among the C resources. Further feedback of C quality indicators corresponding to the C resources is needed. The highest quality among the C quality indicators is fed back using an absolute value method; the rest are fed back using differential feedback with reference to the highest quality. Therefore, after reporting C resource indicators in a combined manner, it is necessary to further feed back the index information of the resource corresponding to the highest quality indicator among the C resource indicators; for example, using... The optimal quality indicator among the C resource indications fed back using a bit-based feedback combination method is indexed in the C resources. The optimal quality indicator is fed back using an absolute value method; for example, if it corresponds to the first quality indicator among the C quality indications, then there is a one-to-one correspondence between the remaining C-1 resource indications and the C-1 quality indications. For example, the terminal's feedback information may include the following information: [C resource indications (occupied...] (bits), the index information of the resource corresponding to the best quality indicator information among the C resources (occupancy) of the C resources, which is one of the C resources. The system consists of C*(C-1) quality indicators (each using differential feedback, occupying 4*(C-1) bits), the optimal quality indicator (occupying 7 bits and using absolute value feedback), and C-1 quality indicators (each using differential feedback, occupying 4*(C-1) bits). In other words, the terminal provides index information for N resources that meet predetermined characteristics from the C resource indicator information. In this application example, N can be 1, and the resources meeting the predetermined characteristics are the resources corresponding to the optimal quality among the C resource indicator information.

[0319] The quality indication information in this embodiment can be one of the following: Channel Quality Indicator (CQI), RSRP, Reference Signal Received Quality (RSRQ), Signal-to-Noise Ratio (SINR), and Block Error Rate (BLER).

[0320] Similarly, the L measurement reference signal resources can also be L synchronization signals.

[0321] In the above embodiment, the C resource indication information is reported in a combined manner, and further, N resource indication information satisfying a predetermined characteristic among the C resource indication information reported in the combined manner is reported. In another optional embodiment of the present embodiment, the C quality indication information can be reported in a combined manner, and further, N quality indication information satisfying a predetermined characteristic among the C quality indication information reported in the combined manner is reported. Alternatively, the C resource indication information is not reported in a combined manner, so that the C resource indication information and the C quality indication information can be one-to-one corresponding.

[0322] Application Example 3

[0323] In the present application example, the base station allocates L measurement reference signal resources to the terminal, and instructs the terminal to select C resources from the L measurement reference signal resources. The terminal needs to feed back resource indication information of the selected C resources and Q quality indication information corresponding to the Q resources to the base station; wherein Q is an integer less than or equal to C.

[0324] Optionally, the terminal further needs to feed back resources satisfying a predetermined characteristic among the C resource indication information to the base station; for example, the predetermined characteristic is that the quality corresponding to the resource is lower than a predetermined threshold; or the difference between the quality corresponding to the resource and a predetermined quality is less than a predetermined threshold.

[0325] For example, the terminal feeds back the C optimal resources in a combined manner; optionally, the terminal further feeds back index information of the N resources satisfying the above predetermined characteristic among the optimal C resources in the feedback in C bits; optionally, the terminal only needs to feed back quality indication information corresponding to the remaining C-N resources, i.e., Q=C-N; wherein the C-N resource indication information and the C-N quality indication information corresponding to the C-N resource indication information except the N resource indication information are sequentially corresponding.

[0326] In another embodiment of the present application example, when the resources satisfying the above predetermined characteristic among the C resources are N, and when the optimal quality of X=C-N resources except the N resources among the C resources is fed back in an absolute value and the remaining quality is fed back in a relative value, at this time, the index information of the optimal quality among the X resources can be fed back, i.e., the feedback information of the terminal includes the following information field: [C resource indication information (occupies C bits), index information of the N resources whose quality is lower than a predetermined threshold among the C resources (occupies C bits), index information of the resource whose optimal quality among the remaining X=C-N resources (occupies X bits)]. ​C resource indication information (occupy 3 bits), index information of N resources in C resources which have quality higher than a predetermined threshold in C resource indication information (occupy C bits), index information of the resource with the best quality in N resources (occupy 3 bits), best quality indication information of N resources (occupy 7 bits), quality indication information of N-1 resources (occupy 4*(X-1) bits).

[0327] In the above manner, N resource comparison poor quality resource indication information is fed back. Of course, the present application example can directly feed back the indication information of N resources with quality higher than a predetermined threshold in the fed back C resource indication information (or feed back the indication information of X resources with quality difference higher than a predetermined threshold from the reference quality in the C resource indication information), that is, the feedback information includes the following information field: [C resource indication information (occupy bits), index information of N resources in C resources which have quality higher than a predetermined threshold in C resource indication information (occupy C bits), index information of the resource with the best quality in N resources (occupy 3 bits), best quality indication information of N resources (occupy 7 bits), quality indication information of N-1 resources (occupy 4*(X-1) bits). bits), index information of N resources in C resources which have quality higher than a predetermined threshold in C resource indication information (occupy C bits), index information of the resource with the best quality in N resources (occupy 3 bits), best quality indication information of N resources (occupy 7 bits), quality indication information of N-1 resources (occupy 4*(X-1) bits).

[0328] In one embodiment of the present embodiment, the feedback information includes the following three items: [C resource indication information; index information of N7 resources in C resources indicated by C resource indication information which satisfy a first predetermined characteristic in C resources; index information of N8 resources in C resources indicated by C resource indication information which satisfy a second predetermined characteristic in C resources]. Wherein N7, N8 are integers less than or equal to C.

[0329] Application Example 4

[0330] In the present application example, the base station allocates L measurement reference signal resources to the terminal, and instructs the terminal to select M resources from the L measurement reference signal resources. The terminal needs to feed back the resource indication information of the selected M resources and the M quality indication information corresponding to the M resources to the base station. Among the M quality indication information, the maximum value is fed back in an absolute value manner, and the remaining quality indication information is fed back in a differential manner, and the reference quality of the differential manner is the best quality in the M quality indication information.

[0331] Since it is intended to feed back the indication information of multiple resources in a combination manner to save feedback overhead, but considering that the resource indication information in the combination manner needs to satisfy the requirement that the index is arranged in order, the resource with the best quality in the multiple resources also needs to be identified, so that the best quality indication information is fed back in an absolute value manner, and the remaining quality indication information is fed back in a differential manner with reference to the best quality.

[0332] To address this, the resource indication information corresponding to the optimal quality and the remaining resource indication information can be fed back as independent bit fields; for example, using... (Index information of the optimal quality resource among L resources) bits represent the optimal quality resource indication information, using... Each bit represents the index information of the remaining M-1 resources in the L-1 resources (i.e., the remaining L-1 resources excluding the resource corresponding to the best quality among the L measurement reference signal resources); where, The value of each bit is in Indicates from L-1-b i When selecting M-1-i resources from a given set of resources, the number of different combinations of the M-1-i resources is... b indicates rounding up. i <b i+1 ,1≤b i ≤L-1,b i This represents the index information of the i-th resource among the M-1 resources in the L-1 resources;

[0333] Or, adopt (Index information of the optimal quality resource among L resources) bits represent the optimal quality resource indication information, using... Each bit represents the index information of the remaining M-1 resources among the L resources. The value of each bit is in Indicates from Lb i When selecting M-1-i resources from a given set of resources, the number of different combinations of the M-1-i resources is... b indicates rounding up. i <b i+1 ,1≤b i ≤L,b i This represents the index information of the i-th resource among the M-1 resources in the L candidate resources;

[0334] That is, the resource indication information of the best quality is fed back using a separate bit field, while the resource indication information of the remaining M-1 is fed back using the combination method described above.

[0335] Application Example 5

[0336] In this embodiment, the terminal feeds back M resource indication information and M quality indication information to the base station, and it is necessary to determine the correspondence between the M resource indication information and the M quality indication information.

[0337] Optionally, there is a one-to-one correspondence between the M resource indications and the M quality indications. The correspondence between the M resource indications and the M quality indications can be determined using one of the following methods:

[0338] Method 1: M resource indication information and M quality indication information correspond sequentially; specifically, taking M=2 as an example, the feedback information first contains resource indication information {CRI1, CRI2}, followed by M quality indication information {RSRP1, RSPR2}, where RSRP1 is the quality indication information of CRI1 and RSPR2 is the quality indication information of CRI2.

[0339] Method 2: The terminal informs the base station of the resource indication information corresponding to the best quality among the M quality indication information in a specific way. The best quality indication information is fed back at a specific position among the M quality indication information; for example, the first quality indication information is the best quality indication information, and the remaining M-1 quality indication information and the remaining M-1 resource indication information correspond sequentially; for example, the M resource indication information is reported in a combined manner, that is, the resource indication information of the M resources is used... Each bit represents, The value of each bit is in Indicates from Lb i When selecting Mi resources from a set of resources, the number of combinations of Mi resources. This indicates rounding up. The M resources are selected from a predetermined L candidate resources, where L is a positive integer greater than or equal to M. i b represents the index information of the i-th resource among the M resources in the L candidate resources. i <b i+1 , 1≤b i ≤L. For example, b i Just for CRI or b i -1 represents CRI (CSI-RS resource indicator); assuming L = 64 and M = 4; the terminal uses... The bits and the combination above reflect {b1, b8, b} 17 ,b 59 The resources selected for this purpose, due to the above combination method, require that b be satisfied in the feedback. i <b i+1 Therefore, the first CRI fed back may not correspond to the CRI with the best quality, so the terminal needs to further feed back the selected {b1, b8, b} to the base station. 17 ,b 59 Of the four resources, b 17For the optimal quality corresponding CRI, the RSRP1 in the base station feedback {RSRP1, RSPR2, RSPR3, RSPR4} corresponds to b 17 The remaining M-1 resource indication information and M-1 quality indication information correspond in order, that is, the quality indication information corresponding to the measurement reference signal resource represented by b1 is RSRP2, the quality indication information corresponding to the measurement reference signal resource represented by b8 is RSRP3, the quality indication information corresponding to the measurement reference signal resource represented by b 59 The quality indication information corresponding to the measurement reference signal resource represented by b

[0340] In the above manner, the number of resource indication information and quality indication information is the same, and the present embodiment also does not exclude the following feedback manner: the terminal feeds back M resource indication information and Q quality indication information, and the correspondence between the M resource indication information and the Q quality indication information can be determined by the following manner.

[0341] Manner three: feedback M resource indication information and Q quality indication information, and further feedback the index information of the Q quality information corresponding Q resource indication information in the M resource indication information; wherein, M is greater than or equal to Q; for example, feedback 2 quality indication information and 4 resource indication information, and feedback the index information of the 2 quality indication information corresponding 2 resource indication information in the feedback 4 resource indication information; for example, feedback with 4 bits, so as to know which 2 resource indication information corresponding to the resource quality of the feedback 4 resource indication information.

[0342] Manner four: feedback M resource indication information and Q quality indication information, and further feedback the index information of the M resource indication information corresponding M quality indication information in the Q quality indication information; wherein, M is less than or equal to Q.

[0343] Application example 6

[0344] In the present application example, the base station allocates L measurement reference signal resources to the terminal, and instructs the terminal to select M resources from the L measurement reference signal resources, and the terminal needs to feed back the indication information of the selected M resources and the M quality indication information corresponding to the M resources to the base station. Among them, the optimal value in the M quality indication information is fed back in an absolute value manner, and the remaining quality indication information in the M quality indication information is fed back in a differential manner, and the reference quality of the differential quality feedback is the optimal quality in the M quality indication information.

[0345] Optionally, according to the value of the quality indication information fed back in the absolute value feedback manner, a mapping table between the index value and the differential value referred to by the quality indication information fed back in the differential manner is determined.

[0346] For example, the mapping table referenced by the quality indication information fed back using absolute value feedback is shown in Table 3. The number of bits used for differential feedback is 'a' bits, or the mapping table of index values ​​and differential values ​​referenced by differential feedback includes 2 mapping items. a There are 2 items. Then, in the mapping table, the first 2 items, excluding the last one... a The difference value corresponding to the i-th term (i starts counting from 1) in the -1 terms is RSRP best RSRP represents the optimal quality achieved by the terminal using absolute value feedback. min This indicates a predetermined minimum quality threshold, such as the minimum value in Table 3, i.e., RSRP. min = -140dBm, meaning quality indications below -140dBm are not within the scope of concern, although other RSRPs cannot be excluded. min Value selection. Specifically, for example, when a=4 and M=4, the absolute value feedback of the optimal quality indication information uses 7 bits for feedback and refers to the mapping table in Table 3. If the index value of the 7-bit field of the optimal quality feedback is 20 (i.e., the feedback quality indication information is an index value in the mapping table), and the optimal quality is -120dBm as obtained from Table 3, then the remaining M-1 qualities use differential feedback. The mapping table between the referenced index value and the differential value is shown in Table 4; where the incrementing step size is...

[0347] If the index value of the 7-bit field of the optimal quality feedback is 90, and referring to Table 3, the optimal quality is -50dBm, then the mapping table between the index values ​​and differential values ​​referenced by the quality indication information of the remaining M-1 qualities using differential feedback is shown in Table 5, where the incrementing step size is...

[0348] Index value Quality value (RSRP) 0 -140 dBm 1 -139 dBm … … 96 -44 dBm

[0349] Table 3

[0350] Index value Differential value (RSRP) 0 -4 / 3 dBm 1 -2*4 / 3 dBm … … 14 -15*4 / 3 dBm 15 Less than -15*4 / 3 dBm

[0351] Table 4

[0352] Alternatively, the increment step size for differential feedback is: Wherein, step0 represents a predetermined differential feedback accuracy, or the index value of differential feedback is increased by 1, and the predetermined step of increasing differential accuracy, such as step0 = 1dBm. In Tables 4-5, the differential values are all negative, i.e. differential value = current quality - reference quality, and equivalently, the differential value can also be positive, i.e. differential value = reference quality - current value. In summary, in this embodiment, the differential feedback accuracy is determined according to the value of the reference quality at the time of differential feedback. Wherein the reference quality at the time of differential feedback indicates that the differential quality of differential feedback is the difference between the current quality and the reference quality. The above determination of differential feedback accuracy by the value of the reference quality corresponding to differential feedback is only an example, and the present embodiment does not exclude other implementations of determining differential feedback accuracy according to the value of the reference quality at the time of differential feedback.

[0355] Optionally, the reference quality indication information of differential feedback can also be notified by the base station to the terminal.

[0356] Application Example 7

[0357] In this embodiment, the base station allocates L measurement reference signal resources to the terminal, and instructs the terminal to select M resources from the L measurement reference signal resources. The terminal needs to feed back the indication information of the selected M resources and the M quality indication information corresponding to the M resources to the base station. The optimal value in the M quality indication information is fed back in an absolute value manner, and the remaining quality indication information in the M quality indication information is fed back in a differential manner, and the reference quality of differential quality feedback is the optimal quality in the M quality indication information.

[0358] Optionally, the mapping table between the index value and the differential value referred by the differential feedback is determined according to the value of the quality indication information fed back in the absolute value feedback mode. Or the number of bits occupied by one quality indication information in the differential feedback is determined according to the value of the quality indication information fed back in the absolute value feedback mode. For example, the mapping table between the index value and the quality indication information referred by the absolute value feedback is shown in Table 5, 97 index values are divided into three intervals {0, 1, …, 33}, {34, 35, …, 67}, {68, 69, …, 96}, when the index value fed back in the absolute value feedback is in the first interval {0, 1, …, 33}, one quality indication information in the differential feedback occupies 3 bits, for example, the mapping relationship table between the index value and the differential value referred by the differential feedback is shown in Table 6, when the index value fed back in the absolute value feedback is in the second interval {34, 35, …, 67}, one quality indication information in the differential feedback occupies 4 bits, as shown in Table 7, when the index value fed back in the absolute value feedback is in the third interval {68, 69, …, 96}, one quality indication information in the differential feedback occupies 5 bits, as shown in Table 8.

[0359] The mapping relationship table between the index value and the differential value in Tables 7-9 is only an example, and the embodiment does not exclude other mapping relationship modes.

[0367] Table 9

[0368] In summary, the mapping relationship between the index value and the differential value referred by the differential feedback is determined according to the value of the reference quality referred by the differential feedback, and optionally, the number of bits required by one quality indication information in the differential feedback is determined according to the value of the reference quality referred by the differential feedback. In the above embodiment, the reference quality of the differential feedback is the optimal quality indication information fed back by the terminal, and of course, the embodiment does not exclude that the reference quality of the differential feedback is notified to the terminal by the base station.

[0369] Application Example 8

[0370] In the application example, the first quality is the optimal quality, and the feedback precision of the rest of the qualities is determined according to the optimal quality, or the feedback load of the rest of the qualities. For example, the greater the quality value of the optimal quality is, the lower the feedback precision of the rest of the qualities is, or the greater the feedback load of the rest of the qualities is. At this time, the optimal quality and the rest of the qualities can be fed back in the absolute value mode, or the optimal quality is fed back in the absolute value mode and the rest of the qualities are fed back in the relative value mode.

[0371] Application example 9

[0372] In the application example, the terminal performs the following steps:

[0373] Step 1: Determine the first quality information;

[0374] Step 2: Determine the quantization information of the second quality information according to the first quality information;

[0375] Step 3: Quantize the second quality information according to the determined quantization information;

The quantization model represents the continuous variable to be quantized as a function of one or more parameters, such as y = f(x1, x2), where f(x1, x2) represents a predetermined function of parameters x1, x2, and the value of the continuous quantity to be quantized is y0, which is brought into the above formula to obtain y0 = f(x1, x2) to obtain the values of x1 and x2.

The terminal refers to the mapping table, finds the corresponding index value of the quantized second quality information in the mapping table, and feeds back the index value to the base station, i.e., the quantized second quality information belongs to the index value set included in the mapping relationship.

[0381] Optionally, the resource required for feeding back the quantized second quality information is determined according to the first quality information, and / or the resource required for feeding back the quantized second quality information is determined according to the quantization information; for example, the greater the first quality information, the more resources required for feeding back the quantized second quality information; or the more accurate the quantization precision, the more resources required for feeding back the quantized second quality information.
