For example, the LCG may be divided into two groups or four groups for the eight LCGs, and the LCG group to which the LCG corresponding to the BSR belongs is indicated by the LCID, that is, different LCIDs are used to represent different LCG groups. . Then use the remaining LCG information to indicate which LCG in the group. For example, LCG 0, 1, 2, and 3 are grouped together, represented by LCID 100101, and LCGs 4, 5, 6, and 7 are grouped into LCID 100101. If at this time, if the LCID indicates 100101 and the LCG information indicates 10, then the specific LCG is known to be 6. For example: as shown in Table 1:

Table 1:

The LCG plus 4 method in the table indicates that the LCG information is represented by the method of adding 4 in the LCG group corresponding to 100101. For example, the LCG information is 10, indicating the 2+4th, that is, the LCG6.

In addition, in this embodiment, the BSR may also be as shown in FIG. 4. The subheader of the MAC CE includes an LCID and an LCG, where the LCG represents LCG information. In this embodiment, all the information of the LCG corresponding to the BSR in the sub-header of the MAC CE can be implemented, and the LCG is grouped, so that the overhead of the BSR can be reduced.

In addition, in the embodiment of the present disclosure, the LCID may be equal to or greater than 6 bits.

Optionally, the LCG group includes 4 LCGs, where the LCG information indicates the LCG corresponding to the BSR by 2 bits; or

The LCG group includes 2 LCGs, and the LCG information indicates the LCG corresponding to the BSR by 1 bit.

In this embodiment, it is possible to indicate the LCG in the LCG group by 2 bits or 1 bit, thereby reducing the overhead of the BSR. And the LCG group includes 2 LCGs, for example, the 8 LCGs are divided into four LCG groups, so that the LCG group can be indicated by 2 bits to further reduce the overhead of the BSR.

Optionally, the sub-header of the MAC CE includes an LCG group identifier, where the LCG group identifier is used to indicate an LCG group to which the LCG corresponding to the BSR belongs, and the SDU of the MAC CE further includes LCG information, where the LCG information An LCG for indicating the BSR in the LCG group; or

The sub-header of the MAC CE includes an LCG group identifier and an LCG information, where the LCG group identifier is used to indicate an LCG group to which the LCG corresponding to the BSR belongs, and the LCG information is used to indicate that the BSR corresponds to the LCG group. LCG.

In this embodiment, the sub-header of the MAC CE may include an LCG group identifier indicating the LCG group to which the LCG corresponding to the BSR belongs, and the LCG information included in the SDU indicates the LCG of the BSR in the LCG group, thereby implementing the sub-header. The header indicates part of the information of the LCG, and the SDU indicates another piece of information to reduce the overhead of the subheader. For example, as shown in FIG. 5, the sub-header of the MAC CE includes an LCG group identifier, an LCID, and an R, where R represents a reserved field.

In addition, in this implementation manner, the LCG corresponding to the sub-head of the MAC CE, including the LCG group identifier and the LCG information, may be used to reduce the overhead of the SDU.

Optionally, the sub-header of the MAC CE includes an LCID, where the LCID is used to indicate an LCG corresponding to the BSR.

In this implementation manner, the LCG corresponding to the BSR may be indicated by the LCID, that is, the LCID may be used to identify different LCGs. For example, it is identified by which 8 different LCIDs which is the short BSR of the LCG or the truncated BSR, thereby indicating the LCG corresponding to the BSR more directly and effectively.

Optionally, the cache size information is used to indicate an index of a cache size, and the sub-header of the MAC CE includes indication information used to indicate whether the cache size is greater than a preset threshold.

The cache size may be a buffer size of the user terminal or the LCG, for example, a plurality of bits, and the preset threshold may be a threshold value preset by the user terminal or the network side device, for example, 100 or 200, and the like. It should be noted that, in the embodiment of the present disclosure, there may be a preset threshold for each cache size index, that is, a preset threshold corresponding to the index of the cache size indicated by the cache size information. Limit. For example, if the cache size information indicates an index of 48012 <BS <=59039, the preset threshold may be 54000, so that the cache size may be further accurately indicated, that is, 48012<BS<=59039, greater than 54000 or less than 54000. For another example, if the cache size information indicates an index of 59039<BS<=72598, the preset threshold is 65000, so that the cache size can be further accurately indicated, that is, 59039<BS<=72598, greater than 65000 or less than 65000.

In this implementation manner, the cache size information is used to indicate an index of the cache size, and the sub-head indicates whether the cache size is greater than a preset threshold, so that the cache size can be more accurately indicated, thereby avoiding the cache size. The index of the buffer size value is relatively small (for example, 64 types), and the buffer size of each level indicates a large span, which makes it impossible to accurately confirm the buffer size of the user terminal. The technical problem of scheduling resources to cause a certain amount of waste.

Optionally, the foregoing indication information includes an LCID, where the LCID is used to indicate whether the buffer size is greater than a preset threshold; or

The indication information includes cache size extension information, where the buffer size extension information is used to indicate whether the buffer size is greater than a preset threshold.

In this implementation manner, the LCID may be used to indicate whether the buffer size is greater than a preset threshold, or indicated by a buffer size extend. For example, a buffer size greater than a certain threshold uses buffer size extend=1 combined with a buffer size bit to indicate an index. For example, a buffer size smaller than a certain threshold is indicated by a buffer size extend=0 combined with a buffer size bit. index. This makes it possible to use a small number of bits to indicate a more accurate cache size to improve the performance of the BSR. In this implementation manner, the format of the BSR may be as shown in FIG. 6. The subheader of the MAC CE includes an LCID, an LCG, and a buffer size extend.

Optionally, the cache size information is used to indicate an index of a cache size, and the subheader of the MAC CE includes an index table corresponding to an index indicating the cache size.

In this implementation manner, the index table used by the BSR may be indicated by the foregoing sub-header, that is, a different index table may be used to indicate the cache size, so that the accuracy of further improving the BSR indication cache size may be implemented. For example, for the same index, the index can be used to indicate that the index is an index in a different index table to achieve indexing of different cache sizes. The index table corresponding to the indication index may be indicated by using the remaining bits of the sub-header, or may be indicated by using an LCID, etc., which is not limited in this embodiment of the disclosure.

Optionally, the sub-header of the MAC CE includes an LCID and a length indication information, where the LCID is used to indicate that the BSR type is a long BSR, and the length indication information is used to indicate a length of the SDU of the MAC CE.

In this embodiment, the BSR type is indicated by the LCID, and the length indication information is used to indicate the length of the SDU of the MAC CE, so that a BSR with a variable length can be provided to improve the flexibility of the BSR and save the BSR overhead. Technical problem, and can indicate the buffer size of multiple LCGs at a time to save transmission overhead. For example, if the BSR only corresponds to one LCG, a short-length BSR can be used. In addition, the above LCID and length indication information may be as shown in Table 2 and Table 3:

Table 2:

索引index	LCID数值LCID value
101100101100	long BSRLong BSR

table 3:

BSR字节标识BSR byte identifier	BSR SDU长度BSR SDU length
0000	22
0101	44
1010	66
1111	88

Wherein, Table 2 represents the LCID, and Table 3 represents the above indication information, for example, the length of the SDU may be indicated as 2, 4, 6, or 8 length units, where the length unit herein may be a buffer size for indicating an LCG. The unit.

In this implementation manner, the format of the BSR may be as shown in FIG. 7, and the number of buffer size information included in the SDU may be changed, that is, the length of the SDU is variable. The length indication information can be understood by the BSR SDU byte identifier in the figure.

Optionally, the SDU length of the MAC CE is corresponding to the sequence number of the target LCG in the at least one LCG corresponding to the BSR, where the target LCG is the LCG with the largest sequence number among the at least one LCG.

In this implementation manner, the length of the SDU can be changed according to the sequence number of the target LCG, so as to effectively save the BSR overhead. For example, for 8 LCGs, if the LCG corresponding to the BSR is 0, 2, and 3, then the length of the SDU is 4. The first cache size information indicates a buffer of the LCG0, the second cache size information may be empty, the third cache size information indicates LCG2, and the fourth cache size information indicates LCG3.

It should be noted that, in this embodiment, the LCG may not be indicated by a bit, and the buffer size of different LCGs may be indicated by a fixed position in the SDU, that is, the location of the buffer size information in the SDU corresponds to the serial number of the LCG. To reduce the overhead of BSR.
