Description

Method and device for information feedback, method and device for receiving information

technical field

This article relates to but not limited to wireless communication technology, especially a method and device for information feedback, and a method and device for receiving information.

Background technique

High-frequency communication is one of the core technologies of the new air interface (NR). High-frequency communication can provide ultra-large bandwidth communication for future communication and greatly improve communication capacity. An important feature of high-frequency communication is based on beam transmission, especially radio frequency beam transmission. Because the path loss of high-frequency signals is relatively large, it is necessary to increase the coverage distance based on beam gain. On the other hand, the wavelength of high-frequency signals is relatively short, which can form a large-scale antenna array and provide the possibility for beam-based communication.

In the system based on beam communication, it is necessary to align the sending beam and receiving beam pair before communication, and because the beam is partially covered, it is easy to be blocked by obstacles, the movement of the communication parties and other factors, and the aligned beam cannot communicate. The fast recovery of beam centering, and considering scenarios such as base station multi-user scheduling, the terminal needs to feed back multiple transmit beams to the base station.

NR determines that the terminal can feed back 4 beams at a time among the 64 transmit beams. At the same time, considering that each transmit beam also needs to feed back the reference signal relative power (RSRP, reference signal relative power), the feedback overhead will be relatively large, and considering the future In the standard version of the standard version, it may be necessary to feed back more beams in more sending beams, and to feed back the quality information of each beam, so it is necessary to consider how to reduce the feedback overhead of multi-beam feedback; currently, there is no way to reduce multi-beam Scenarios for feedback on overhead issues.

The method of the embodiments of the present disclosure will be clearly and detailedly described below through application examples. The application examples are only used to illustrate the present disclosure, and are not intended to limit the protection scope of the present disclosure.

Application example 1

In this application example, the base station indicates to the terminal that it needs to select at most M_max measurement reference signal resources from the L measurement reference signal resources to report to the base station; or, the base station and the terminal agree that the terminal can use the L measurement reference signal resources At most M_max measurement reference signal resources are selected and reported to the base station. According to the actual measurement situation, the terminal may only report M measurement reference signal resources and M quality indication information corresponding to the M measurement reference signal resource indication information; or, the terminal may only report M measurement reference signal resource indications according to the actual measurement situation The information and Q quality indication information corresponding to (Q) measurement reference signal resources; wherein, M and Q are integers less than or equal to M_max. Since M and Q are allowed to be smaller than M_max, the terminal needs to feed back the information of M and Q to the base station. This can be done in the following ways:

Mode 1: The terminal has a bit field in the feedback information, and the bit field is used to indicate the M and/or Q value; for example, the information field fed back by the terminal is as follows [M value (occupancy bits), M resource indication information, Q value bits), Q quality indication information], optional, when it is agreed that M and Q are always the same, only the M value can be fed back, that is, for example, the feedback information is (M value (occupancy bits), M pieces of resource indication information, M pieces of quality indication information).

Optionally, the number of bits occupied by the M resource indication information may be determined according to the M value; for example, the number of bits occupied by the M resource indication information is bits. Since the base station does not know the M value actually selected by the terminal, it will follow the Assign feedback resources to the terminal, when M is less than M_max, if less than then you can put bits are repeated to form bits; for example is 3 bits, is 8 bits, then the Repeat 3 times, and discard the last bit of the last repetition; wherein, the M resources are selected from the L resources.

Mode 2: The terminal uses the first designated value in the feedback information to indicate the terminators of the M resource indication information, and/or uses the second designated value in the feedback information to indicate the terminators of the Q quality indication information; for example, the terminal feedback The information is (M pieces of resource indication information, the terminator of the resource indication information, Q pieces of quality indication information, the terminator of the quality indication information); optionally, the bit occupied by each resource indication information in the M resource indication information The number of bits is the same as the number of bits occupied by the terminator of the resource indication information; for example, each resource indication information uses bit representation, also used bits represent the terminator of the resource indication information; for example, use L+y to represent the terminator of the resource indication information; wherein, y is a non-negative integer, that is, use the L value to represent the terminator of the M resource indication information; for example, L= 7. M=2, then the terminal uses two 3-bit feedback resource indication information of the selected 2 resources, and then uses 3 bits and a value of 7 to indicate the end of the M resource indication information, that is, the last bit of the M resource indication information Always followed by a terminator for resource indication information.

Table 1

index value Quality Value (RSRP) 0 -140dBm 1 -139dBm … … 96 -44dBm 97 end of quality information

Table 2

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

Method 3: 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 number of resources fed back by the terminal, resources are allocated according to the maximum M_max, and the terminal determines M resource indications according to the actual feedback M value The number of bits required for the information, 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 the terminal feeds back according to the number of bits occupied by the M resource indication information; CRC protection, the base station can know the M value selected by the terminal through blind detection. Similarly, the terminal feeds back Q pieces of quality indication information, and the base station obtains the Q value selected by the terminal through blind detection. That is, the M and Q values are not fed back in the feedback information of the terminal, and the base station obtains the M value through blind detection of M resource indication information, and/or obtains the Q value through blind detection of Q quality indication information, or obtains the Q value through blind detection of M resource indication information. information and Q pieces of quality indication information to obtain the combined value of M and Q. That is, the feedback information of the terminal may only occupy part of the feedback resources allocated by the base station. The feedback resource may be a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), and the like. Optionally, at this time, the number of bits occupied by the M pieces of resource indication information corresponding to different M values is different, and the number of bits occupied by the Q pieces of quality indication information corresponding to different Q values is different.

Method 4: The terminal feeds back the M value through the number of repetitions of sent bits; for example, since the base station does not know the actual number of resources fed back by the terminal, resources are allocated according to the maximum M_max, and the terminal determines the bits required for 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, then the terminal expands the number of bits occupied by the M resource indication information to M_max resources indicate the number of bits occupied by the information. For example, the number of bits occupied by M_max resource indication information is 12. When the number of bits occupied by M resource indication information is 6, the M resource indication information can be repeated twice to form 12 bits; The number of bits in is the number of bits after channel coding (the number of bits occupied in the foregoing description may 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 a 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 through repetition.

Mode 5: Feedback Q pieces of quality indication information; wherein, when the quality indication information is lower than the 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, then The resource indication domain value feeds back 3 resource indication information, that is, M=3, and the Q quality indication information is in front of the M resource indication information.

Optionally, the M is a minimum value between M_max and M1, where M1 is the number of resources among the L measurement reference signal resources that satisfy a first predetermined characteristic, and the first predetermined characteristic satisfies at least one of the following characteristics: The M1 resources are resources whose quality value is greater than a predetermined threshold among the L qualities corresponding to the L candidate resources; the M1 resources are resources whose correlation between the L candidate resources and the predetermined resource is less than a predetermined threshold ; The M1 resources are resources whose difference between the L qualities corresponding to the L candidate resources and the predetermined quality is greater than a predetermined threshold, where M1 is a non-negative number.

Optionally, the Q is the minimum value between M_max and Q1, where Q1 is the number of quality information that satisfies the second predetermined feature among the L pieces of quality information corresponding to the L measurement reference signal resources, and the second predetermined The feature satisfies at least one of the following features: the quality corresponding to the Q1 quality indication information is the quality whose quality value is greater than the fourth predetermined threshold among the L qualities corresponding to the L candidate resources; the quality corresponding to the Q1 quality indication information is the L candidate resource Among the corresponding L qualities, the correlation with the quality of the predetermined resource is less than the quality of the fifth predetermined threshold; the quality corresponding to the Q1 quality indication information is the second predetermined quality among the L qualities corresponding to the L candidate resources. The difference is greater than the quality of the sixth predetermined threshold.

Similarly, the L measurement reference signal resources may also be L synchronization signals.

Application example 2

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, and the terminal needs to share the resource indication information of the selected C resources with the C The C pieces of quality indicator information corresponding to the resources are fed back to the base station. Among them, the optimal value (such as the maximum value) in the C quality indication information is fed back in an absolute value mode, and the remaining quality indication information in the C quality indication information is fed back in a differential mode, and the reference quality of the differential quality feedback is the C quality indication information best quality in .

The indication information of the C resources indicates 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 Symbol (CSI-RS) resources, and the resource indication information is CRI (CSI-RS resource indicator).

In order to save bits, the C resource indication information uses bits represent;

The C resource indication information is used express;

in, Indicates the number of different combinations of Ci resources when Ci resources are selected from Lb _i resources, Indicates rounding up, the C resources are selected from the predetermined L candidate resources, the L is a positive integer greater than or equal to C, and b _i is the i-th resource among the C resources in the L Index information in candidate resources, b _i <b _i+1 , 1≤b _i ≤L.

Although using a combined approach compared to using each resource The bit feedback method saves the feedback overhead, but the above combined feedback method needs to satisfy b _i <b _i+1 , so the quality of the first CRI fed back is not necessarily the resource with the best quality among the C resources. C pieces of quality indication information corresponding to the C resources are further fed back. Among the C quality indication information, the optimal quality is fed back in the form of absolute value; for the rest, the quality refers to the optimal quality and adopts differential feedback. Therefore, after reporting C resource indication information in a combined manner, it is necessary to further feed back the index information of the resource corresponding to the best quality indication information among the C resource indication information in the C resources; for example, using The resource indication information corresponding to the best quality indication information in the C resource indication information fed back by bit feedback combination is the index information in the C resources, and the optimal quality indication information is fed back in absolute value mode, for example, corresponding to C quality indications The first quality indication information in the information, the remaining C-1 resource indication information and the C-1 quality information indication information are in one-to-one correspondence. For example, the feedback information of the terminal includes the following information [C resource indication information (possession bits), the index information of the resources corresponding to the best quality indication information among the C quality indication information corresponding to the C resources in the C resources (occupancy bits), optimal quality indication information (occupies 7 bits, adopts absolute value feedback), C-1 quality indication information (each quality indication information adopts differential feedback, occupies 4*(C-1) bits)]. That is, the terminal feeds back the index information of N resources that meet the predetermined characteristics in the feedback C resource indication information; in this application example, N can take a value of 1, and the resources that meet the predetermined characteristics are the C quality indicators corresponding to the C resources The resource corresponding to the best quality of information.

In the embodiments of the present disclosure, the quality indication information may be one of the following quality indication information: channel quality indication (CQI), RSRP, reference signal received quality (RSRQ), signal-to-noise ratio (SINR), and block error rate (BLER).

Similarly, the L measurement reference signal resources may also be L synchronization signals.

In the above embodiment, the C resource indication information is reported in a combined manner, and N resource indication information satisfying predetermined characteristics among the C resource indication information reported in the combined manner is further reported. Another optional implementation mode of this embodiment In this method, the C pieces of quality indication information may be reported in a combined manner, and N pieces of quality indication information satisfying predetermined characteristics among the C pieces of quality indication information reported in the combined manner may be further reported. Optionally, at this time, the C pieces of resource indication information are not reported in a combined manner, so that the C pieces of resource indication information and the C pieces of quality indication information can be in one-to-one correspondence.

Application example 3

In this application example, the base station allocates L measurement reference signal resources to the terminal, and instructs the terminal to select C resources among the L measurement reference signal resources, and the terminal needs to share the resource indication information of the selected C resources and the Q The Q pieces of quality indicator information corresponding to the resources are fed back to the base station; wherein, Q is an integer less than or equal to C.

Optionally, the terminal further needs to feed back to the base station the resources that meet the predetermined characteristics among the C resource indication information; 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 the predetermined quality is less than predetermined threshold.

For example, the terminal feeds back C optimal resources in a combined manner; optionally, the terminal further indicates the index information of N resources in the C resources that satisfy the above predetermined characteristics among the optimal C resources fed back through C bits; optional Therefore, the terminal only needs to feed back the quality indication information corresponding to the remaining C-N resources, that is, Q=C-N; wherein, among the C resource indication information, the C-N resource indication information except the N resource indication information and the C-N Corresponds to the sequence of quality indication information.

In another implementation of this application example, when there are N resources among the C resources that meet the above predetermined characteristics, when the C resources except the N resources are X=the best quality among the C resources When absolute value feedback is used and relative value feedback is used for the rest of the quality, index information in the X resources of the best quality among the X resources can be fed back at this time, that is, the feedback information of the terminal includes the following information field [C resource indication information (Possession bits), the N resources whose quality is lower than the predetermined threshold in the C resources index information in the C resources (occupying C bits), and the resource with the best quality among the remaining X=CN resources is in the X resources Index information (possessing bits), the best quality indication information in X resources (using absolute value feedback, occupying 7 bits), X-1 quality indication information (using relative value feedback, occupying 4*(X-1)) bits] . The C resources are represented by the C resource indication information.

In the above method, N resource indication information with relatively poor quality is fed back. Of course, this application example can directly feed back the indication information of N resources whose quality is higher than the predetermined threshold among the fed back C resource indication information (or feed back C resource indication information Indication information of X resources whose difference between quality and reference quality in the information is higher than a predetermined threshold), that is, the feedback information includes the following information fields: [C resource indication information (occupancy bits), among the C resources, the N resources whose quality is higher than the predetermined threshold index information in the C resources (occupying C bits), and the resources with the best quality among the N resources index information in the N resources (occupying bits), the best quality indication information among N resources (using absolute value feedback, occupying 7 bits), the quality indication information of N-1 resources (using relative value feedback, occupying 4*(X-1)) bits).

In an implementation of this embodiment, the feedback information includes the following three items: [C resource indication information; among the C resources represented by the C resource indication information, the N7 resources that meet the first predetermined feature are included in the C resources. the index information in the C resources; the index information of the N8 resources in the C resources that satisfy the second predetermined feature among the C resources represented by the C resources indication information]. Where N7, N8 are integers less than or equal to C .

Application example 4

In this 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 share the resource indication information of the selected M resources with the M M pieces of quality indicator information corresponding to the resources are fed back to the base station. Among them, the maximum value of the M quality indication information is fed back in an absolute value mode, and the remaining quality indication information in the M quality indication information is fed back in a differential mode, and the reference quality fed back in the differential mode is the optimal quality among the M quality indication information.

Because I want to feed back the indication information of multiple resources in a combined way to save feedback overhead, but considering that the resource indication information in the combined mode needs to meet the requirements of index ordering, it is also necessary to identify the resource with the best quality among multiple resources. Therefore, the optimal quality indication information is fed back in an absolute value manner, and the rest of the quality indication information is fed back in a differential manner with reference to the optimal quality.

In this regard, the resource indication information corresponding to the best quality and the remaining resource indication information can be divided into independent bit field feedback; for example, using (represents the index information of the resource with the best quality in L resources) bits represent the resource indication information with the best quality, using bits represent the index information of the remaining M-1 resources in L-1 resources (that is, the remaining L-1 resources except the resources corresponding to the best quality in the L measurement reference signal resources); where, The value of a bit is in Indicates the number of different combinations of M-1-i resources when selecting M-1-i resources from L-1-b _i resources, Represents rounding up, b _i <b _i+1 , 1≤b _i ≤L-1, b _i represents the index information of the i-th resource among the M-1 resources in the L-1 resources;

Alternatively, use (represents the index information of the resource with the best quality in L resources) bits represent the resource indication information with the best quality, using bits represent the index information of the remaining M-1 resources in the L resources. in, The value of a bit is in Indicates the number of different combinations of M-1-i resources when selecting M-1-i resources from Lb _i resources, Represents rounding up, b _i <b _i+1 , 1≤b _i ≤L, b _i represents the index information of the i-th resource among the M-1 resources in the L candidate resources;

That is, the resource indication information of the best quality is fed back in a separate bit field, and the resource indication information of the remaining M-1 is fed back in the above combination manner.

Application example 5

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

Optionally, there is a one-to-one correspondence between the M pieces of resource indication information and the M pieces of quality indication information. The correspondence between the M pieces of resource indication information and the M pieces of quality indication information can be determined in one of the following ways:

Mode 1: M pieces of resource indication information correspond to M pieces of quality indication information in sequence; specifically, taking M=2 as an example, the feedback information first includes resource indication information {CRI1, CRI2}, and then M pieces of quality indication information {RSRP1 , RSPR2}, then RSRP1 is the quality indication information of CRI1, and RSPR2 is the quality indication information of CRI2.

Mode 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, and the optimal quality indication information is fed back at a specific position among the M quality indication information; for example, the first quality indication information is is the optimal quality indication information, and the remaining M-1 quality indication information corresponds to the remaining M-1 resource indication information in sequence; for example, M resource indication information is reported in a combined manner, that is, the resource indication information of M resources bits represent, The value of a bit is in Indicates the number of combinations of Mi resources when Mi resources are selected from Lb _i resources, Indicates rounding up, the M resources are selected from the predetermined L candidate resources, the L is a positive integer greater than or equal to M, and b _i is the i-th resource among the M resources in the L candidate resources The index information in b _i <b _i+1 , 1≤b _i ≤L. For example, _bi is CRI or _bi -1 is CRI (CSI-RS resource indicator); assuming L=64, M=4; the terminal adopts bits and the above combination method feeds back the resource selected by {b ₁ ,b ₈ ,b ₁₇ ,b ₅₉ }, since the above combination method feedback needs to satisfy b _i < _bi+1 , so the first feedback A CRI does not necessarily correspond to the CRI with the best quality, so the terminal needs to further feed back the selected four resources {b ₁ , b ₈ , b ₁₇ , b ₅₉ } to the base station, b ₁₇ is the CRI corresponding to the best quality. Then In the {RSRP1, RSPR2, RSRP3, RSPR4} fed back by the base station, RSRP1 corresponds to b ₁₇ , and the remaining M-1 resource indication information corresponds to M-1 quality indication information in sequence, that is, the quality corresponding to the measurement reference signal resource represented by b ₁ The indication information is RSRP2, the quality indication information corresponding to the measurement reference signal resource represented by b ₈ is RSRP3, and the quality indication information corresponding to the measurement reference signal resource represented by b ₅₉ is RSRP4.

In the above method, the number of resource indication information and quality indication information is the same, this embodiment does not exclude the following feedback mode, the terminal feeds back M resource indication information and Q quality indication information, there are M resources that can be determined by the following method Correspondence between indication information and Q quality indication information.

Mode 3: Feed back M pieces of resource indication information and Q pieces of quality indication information, and further feed back the index information of the Q pieces of resource indication information corresponding to the Q pieces of quality information in the M pieces of resource indication information; wherein, M is greater than or equal to Q; for example, Feed back 2 quality indication information and 4 resource indication information, and feed back the index information of the 2 resource indication information corresponding to the 2 quality indication information in the 4 feedback resource indication information; for example, use 4 bits to feed back, so that the feedback The 2 pieces of quality indication information are about the quality of the resource corresponding to which 2 resource indication information among the 4 feedback resource indication information.

Mode 4: Feed back M pieces of resource indication information and Q pieces of quality indication information, and further feed back the index information of the M quality indication information corresponding to the M resource indication information in the Q quality indication information; where M is less than or equal to Q.

Application example 6

In this 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 share the indication information of the selected M resources and the The corresponding M pieces of quality indicator information are fed back to the base station. Among them, the optimal value of the M quality indication information is fed back in the absolute value mode, and the remaining quality indication information in the M quality indication information is fed back in the differential mode, and the reference quality of the differential parameter quality feedback is the best quality among the M quality indication information. quantity.

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

For example, the mapping table referenced by the quality indication information fed back in the absolute value feedback mode is shown in Table 3, and the number of bits used for the differential feedback is a bit, or included in the mapping table of the index value and the differential value referenced by the differential mode feedback Mapping items are 2 ^a items. Then in the mapping table, the difference value corresponding to the i-th (i starts counting from 1) item in the first ^2a -1 items except the last item is Among them, RSRP _best indicates the optimal quality of the terminal using absolute value feedback, and RSRP _min indicates the predetermined minimum quality threshold. For example, the minimum value in Table 3 can be used, that is, RSRP _min = -140dBm, that is, the quality indication information lower than -140dBm is not concerned Of course, other values of RSRP _min are not excluded. Specifically, for example, a=4, M=4, the absolute value mode feedback optimal quality indication information adopts 7-bit feedback and refers to the mapping table in Table 3. If the index value of the feedback optimal quality 7-bit field is 20 (that is, the feedback quality indication information is an index value in the mapping table), referring to Table 3, the optimal quality is -120dBm, and the remaining M-1 quality adopts differential feedback The mapping table between the referenced index value and the difference value is shown in Table 4; wherein, the incremental step size is

If the index value of the feedback optimal quality 7-bit field is 90, and the optimal quality is obtained by referring to Table 3 to be -50dBm, then the remaining M-1 qualities adopt the index value and the differential value referred to by the quality indication information of differential feedback The mapping table is shown in Table 5, where the incremental step size is

index value Quality Value (RSRP) 0 -140dBm 1 -139dBm … … 96 -44dBm

table 3

index value Differential value (RSRP) 0 -4/3dBm 1 -2*4/3dBm … … 14 -15*4/3dBm 15 Less than -15*4/3dBm

Table 4

Alternatively, the incremental step size for differential feedback is: Wherein, step ₀ represents a predetermined differential feedback precision, or a predetermined step size for increasing the differential precision by increasing the index value of the differential feedback by 1, for example, step ₀ =1 dBm. In Tables 4-5, the differential values are all negative, that is, differential value=current quality-reference quality, and equivalently, the differential value can also be positive, that is, differential value=reference quality-current value. In a word, in this embodiment, the differential feedback accuracy is determined according to the value of the reference quality during differential feedback. The reference quality during differential feedback means that the differential quality of differential feedback is the difference between the current quality and the reference quality. The determination of the differential feedback accuracy based on the value of the reference quality corresponding to the differential feedback is just an example, and this embodiment does not exclude other implementations in which the differential feedback accuracy is determined according to the value of the reference quality during differential feedback.

index value Differential value (RSRP) 0 -6dBm 1 -2*6dBm … … 14 -15*6dBm 15 Less than -15*6dBm

Optionally, the reference quality indication information of the differential feedback may also be notified by the base station to the terminal.

Application example 7

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, and the terminal needs to combine the indication information of the selected M resources with the M The M pieces of quality indicator information corresponding to the resources are fed back to the base station. Among them, the optimal value of the M quality indication information is fed back in the form of absolute value, and the rest of the quality indication information in the M quality indication information is fed back in the differential mode, and the reference quality of the differential parameter quality feedback is the optimal quality of the M quality indication information .

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

The mapping relationship tables between index values and difference values in Tables 7-9 are just examples, and this embodiment does not exclude other mapping relationship modes.
