Description

Information reporting method and communication device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 28, 2022, with application number 202211196975.7 and application name “A Method and Communication Device for Reporting Information”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to an information reporting method and a communication device. Background Art

[0003] With the development of the times, people have begun to study extended reality (XR) technology. XR services require large amounts of data to be transmitted. Therefore, during the data transmission process, a large amount of data is buffered in the logical channel. The terminal device sends a buffer status report (BSR) to the network device to inform the network device of the total amount of data buffered in the logical channel that needs to be sent.

[0004] The buffer status report usually indicates how much data is included in a logical channel group by means of an index and an index table. For example, the following Table 1 is an index table in the prior art:

[0005] Table 1

[0006] Exemplarily, assuming that the index corresponding to the first logical channel group indicated in the buffer status report is 16, according to Table 1, it can be determined that the data size cached in the first logical channel group is greater than 1038 bytes and less than or equal to 1446 bytes.

[0007] In Table 1, except for index 0 and index 1, the ratio of the maximum cache intervals corresponding to two adjacent indexes is 1.4. Therefore, the larger the index, the larger the range of the indicated cache data size. For example, when the index is 2, the size of the corresponding cache data is greater than 10 bytes and less than or equal to 14 bytes, and the range interval length is 4 bytes; if the index is 30, the size of the corresponding cache data is greater than 107669 bytes and less than or equal to 150000 bytes, and the range interval length is 42331 bytes. Since the larger the index, the larger the range of the indicated cache data size, this will cause the network device to allocate resources irrationally when scheduling resources according to the BSR of the terminal device. For example, excessive resources may be allocated to the terminal device.

[0008] Therefore, the existing technology hopes to solve the above problem by introducing a new and more fine-grained index table. At the same time, depending on different application scenarios, terminal devices may use different index tables. Therefore, how to distinguish which index table among multiple tables an index corresponds to is an urgent problem that needs to be solved.

[0108] In addition, in the embodiments of the present application, a terminal device may refer to a device for implementing a function of the terminal device, or may refer to a device that supports the terminal device in implementing the function, such as a chip system, which may be installed in the terminal device. For example, the terminal device may also be a vehicle detector or a sensor at a gas station.

[0109] Based on the above introduction to the communication system, the background of the embodiments of the present application is introduced below.

[0110] With the development of the times, people have begun to study extended reality (XR) technology. XR services require large amounts of data to be transmitted. Therefore, during the data transmission process, a large amount of data is buffered in the logical channel. The terminal device sends a buffer status report (BSR) to the network device to inform the network device of the total amount of data buffered in the logical channel that needs to be sent.

[0111] The buffer status report usually indicates how much data is included in a logical channel group by means of an index and an index table. For example, the following Table 1 is an index table in the prior art:

[0112] Table 1

[0113] Exemplarily, assuming that the index corresponding to the first logical channel group indicated in the buffer status report is 16, according to Table 1, it can be determined that the data size cached in the first logical channel group is greater than 1038 bytes and less than or equal to 1446 bytes.

[0114] In Table 1, except for index 0 and index 1, the ratio of the maximum cache intervals corresponding to two adjacent indexes is 1.4. Therefore, the larger the index, the larger the range of the indicated cache data size. For example, when the index is 2, the size of the corresponding cache data is greater than 10 bytes and less than or equal to 14 bytes, and the range interval length is 4 bytes; if the index is 30, the size of the corresponding cache data is greater than 107669 bytes and less than or equal to 150000 bytes, and the range interval length is 42331 bytes. Since the larger the index, the larger the range of the indicated cache data size, this will cause the network device to allocate resources irrationally when scheduling resources according to the BSR of the terminal device. For example, excessive resources may be allocated to the terminal device.

[0115] Therefore, existing technologies attempt to address this issue by introducing a new, more fine-grained index table. However, the definition and type of this index table are not yet established, and terminal devices may use different index tables depending on different application scenarios. Therefore, how to distinguish which index table an index corresponds to among multiple tables is an urgent problem that needs to be solved.

[0116] In order to be able to distinguish the index table corresponding to the index, the embodiment of the present application proposes an information reporting method, please refer to Figure 2. As shown in Figure 2, the information reporting method includes the following steps 201 to 202. The execution subject of the method shown in Figure 2 can be a terminal device and a network device, or the execution subject can be a chip in the terminal device or a chip of the network device. Figure 2 uses the terminal device and the network device as an example to illustrate the execution subject of the method, and the embodiment of the present application does not limit the execution subject of the method. Among them:

[0117] 201. A terminal device obtains first information, where the first information is used to indicate a first index or the first information is used to indicate an index table corresponding to a first index, where the first index corresponds to one of at least two index tables.

[0118] In an embodiment of the present application, a first index is used to indicate second information of a first granularity, wherein an index table includes a correspondence between the index and the second information. The first index corresponds to one of at least two index tables. It can be understood that the first index is an index from one of the at least two index tables, and the second information of the first granularity indicated by the first index is determined by the first index and the index table corresponding to the first index. Optionally, the second information can be the maximum value, minimum value, or middle value in an interval in an index table, or the length of the interval, or the maximum value, minimum value, or middle value in the index table. The at least two index tables include a first index table and a second index table. It should be noted that the first index table and the second index table are only examples provided in the present application. The at least two index tables may also include multiple index tables such as a third index table. The embodiment of the present application does not limit the number of index tables. The first index table and the second index table will be used as examples in the subsequent content. The embodiment of the present application does not limit the number of index tables included in the at least two index tables. Optionally, one of the at least two index tables is an index table defined in the current 3GPP R17 standard V17.2.0, such as Table 1 in the above description.

[0119] In one possible implementation, the first granularity may be one of the following granularities: logical channel (LCH), logical channel group (LCG), protocol data unit set (PDU set), quality of service flow (QoS Flow). Optionally, the first index is an index carried in a buffer status report (BSR), the first granularity is LCG, and the second information is a cache interval. In this implementation, the first index is used to indicate the cache interval corresponding to the data size cached by the LCG. Specifically, the cache interval corresponding to the data size cached by the LCG can be determined by the first index and the table corresponding to the first index.

[0120] Among them, the BSR format can be divided into a short BSR format and a long BSR format.

[0121] As shown in Figure 3, Figure 3 is a schematic diagram of the format of the short BSR provided in an embodiment of the present application. The short BSR only includes an LCG identifier and the first index corresponding to the LCG. The short BSR includes 1 byte, the field length corresponding to the LCG identifier is 3 bits, and the field length corresponding to the first index is 5 bits.

[0122] As shown in Figure 4, Figure 4 is a schematic diagram of the format of the extended short BSR provided in an embodiment of the present application. The extended short BSR only includes an LCG identifier and the first index corresponding to the LCG. The extended short BSR includes 2 bytes, the field length corresponding to the LCG identifier is 8 bits, and the field length corresponding to the first index is 8 bits.

[0123] As shown in Figure 5, Figure 5 is a schematic diagram of the long BSR format provided by an embodiment of the present application. The long BSR can be used to indicate the first index corresponding to 8 LCGs, wherein the long BSR includes m+1byte, and the field length corresponding to the first index is 8bit. m is the number of bits corresponding to the LCG in the BSR as the first bit, and the value range of m is 1 to 8. If LCG i When the corresponding bit is the first bit, it means that the BSR contains LCG i The corresponding first index, if LCG i When the corresponding bit is the second bit, it means that the BSR does not contain the LCG iThe corresponding first index. The value range of i is 0 to 7. The first bit is 0 and the second bit is 1, or the first bit is 1 and the second bit is 0. For example, assuming that in a long BSR, the bit corresponding to LCG0 to LCG3 is the first bit, and the bit corresponding to LCG4 to LCG7 is the second bit. It can be understood that the first index 0 indicates the cache interval corresponding to the data size cached by LCG0, the first index 1 indicates the cache interval corresponding to the data size cached by LCG1, the first index 2 indicates the cache interval corresponding to the data size cached by LCG2, and the first index 3 indicates the cache interval corresponding to the data size cached by LCG3. In the long BSR, LCG4 to LCG7 do not contain the corresponding first index.

[0124] As shown in Figure 6, Figure 6 is a schematic diagram of the extended long BSR format provided by an embodiment of the present application. The extended long BSR can be used to indicate the first index corresponding to 256 LCGs, wherein the long BSR includes m+32byte, the field length corresponding to the first index is 8bit, m is the number of LCGs corresponding to the first bit in the BSR, and the value range of m is 1 to 256. Similar to the above long BSR format, if LCG i When the corresponding bit is the first bit, it means that the BSR contains the LCG i The corresponding first index, if LCG i When the corresponding bit is the second bit, it means that the BSR does not contain the LCG i The corresponding first index. The value range of i is 0 to 255. The first bit is 0 and the second bit is 1, or the first bit is 1 and the second bit is 0.

[0125] The first index is used to indicate the cache interval corresponding to the data size of the LCG cache. Specifically, the cache interval corresponding to the data size of the LCG cache can be determined by the first index and the table index corresponding to the first index. For example, the following Table 2 and Table 3 are used as examples:

[0126] Table 2

[0127] Table 3

[0128] Assuming that the first information indicates that the first index A is 2, and the table corresponding to the first index A is Table 2 of the two index tables mentioned above, it can be determined that the size of the logical channel group buffer data indicated by the first index A is within the buffer range of 2 bytes to 4 bytes. Assuming that the first information indicates that the first index B is 2, and the table corresponding to the first index B is Table 3 of the two index tables mentioned above, it can be determined that the size of the logical channel group buffer data indicated by the first index A is within the buffer range of 10 bytes to 14 bytes.

[0129] In one possible implementation, the first information may indicate the first index or the index table corresponding to the first index in the following manner, thereby determining that the first index corresponds to one of the at least two index tables. It should be noted that the first information may also indicate the first index or the index table corresponding to the first index in other manners, which is not limited in this embodiment of the present application.

[0130] 1. The first information indicates the first index:

[0131] Method 1: The first information is used to indicate the data type or format, and the data format may include a first index, or include information indicating the first index. Optionally, the first information is a logical channel identifier (LCID). Exemplarily, the at least two index tables include a first index table and a second index table. When the LCID corresponding to the data format is the first LCID, the data format can be determined by the first LCID, and the data format includes the first index or includes information indicating the first index, wherein the table corresponding to the first index is the first index table, and therefore the index table corresponding to the first index can be determined by the first LCID as the first index table; when the LCID corresponding to the data format is the second LCID, the data format can be determined by the second LCID, and the data format includes the first index or includes information including the first index, wherein the index table corresponding to the first index is the second index table, and therefore the index table corresponding to the first index can be determined by the second LCID as the second index table. Based on this implementation method, it is advantageous to be able to determine a specific table corresponding to the first index from multiple index tables.

[0132] Method 2: The first information is a first index. In this implementation method, the index table corresponding to the first index can be determined based on the value of the first index. For example, at least two index tables include a first index table and a second index table. If the first information is greater than the first threshold, the first information indicates that the index table corresponding to the first index is the first index table; if the first information is less than or equal to the first threshold, the first information indicates that the index table corresponding to the first index is the second index table. Alternatively, if the first information is greater than or equal to the first threshold, the first information indicates that the index table corresponding to the first index is the first index table; if the first information is less than the first threshold, the first information indicates that the index table corresponding to the first index is the second index table. The first index table and the second index table can form one index table, or be two different index tables. Optionally, the first threshold can be configured by a network device or predefined. Based on this implementation method, it is beneficial to be able to determine a specific table corresponding to the first index.

[0133] 2. The first information is used to indicate the index table corresponding to the first index:

[0134] Method three, the first information is used to indicate the index table corresponding to the first index. Optionally, the first information can be an indication information newly defined in the present application, and the indication information directly indicates the index table corresponding to the first index. Further optionally, the first index is an index carried in the BSR, and the first information is an indication in the data format carrying the BSR, and the first information indicates the index table corresponding to the first index. Exemplarily, as shown in Figure 7, Figure 7 is a schematic diagram of a new long BSR format provided by an embodiment of the present application. The long BSR format includes 8 indications, and the first information is the indication, wherein indication i indicates the index table corresponding to the first index corresponding to LCGi, and the value range of i is 0 to 7. Assuming that at least two index tables include a first index table and a second index table, if the bit corresponding to indication i is the first bit, it means that LCG i The index table corresponding to the first index is the first index table. If the bit corresponding to the indicator i is the second bit, it means LCG i The index table corresponding to the corresponding first index is the second index table. The first bit is 0, and the second bit is 1, or the first bit is 1, and the second bit is 0. The extended long BSR format can also define a new BSR format based on this method, and the new BSR includes 256 indications. The specific implementation method is the same as the implementation method of the long BSR, and will not be repeated here. Among them, the embodiment of the present application only describes how the indication information indicates the index table corresponding to the first index in the case of two index tables. If the number of index tables is multiple, the indication information can also use a similar method to indicate the index table corresponding to the first index. The embodiment of the present application does not limit this. Based on this implementation method, it is beneficial to be able to determine a specific table corresponding to the first index from multiple index tables.

[0135] Based on the above introduction to the first information, the index table will be mainly introduced below.

[0136] In one possible implementation, at least two index tables include a first index table and a second index table, and the adjacent difference in the first index table is smaller than the adjacent difference in the second index table, or the adjacent ratio in the first index table is smaller than the adjacent ratio in the second index table, the adjacent difference is the difference between the second information corresponding to two adjacent indexes in the index table, and the adjacent ratio is the ratio between the second information corresponding to two adjacent indexes in the index table.

[0137] Wherein, if there are adjacent differences in the first index table that are smaller than those in the second index table, this can be understood as follows: the first index table includes multiple adjacent differences, the second index table includes multiple adjacent differences, and at least one of the multiple adjacent differences in the first index table is smaller than the adjacent differences in the second index table. Similarly, if there are adjacent ratios in the first index table that are smaller than those in the second index table, this can be understood as follows: the first index table includes multiple adjacent ratios, the second index table includes multiple adjacent ratios, and at least one of the multiple adjacent ratios in the first index table is smaller than the adjacent ratios in the second index table.

[0138] Optionally, when the first index is an index carried in the BSR, the first granularity is LCG, and the second information here can be understood as the maximum value, minimum value, median value or length of the cache interval corresponding to the first index. Taking the second information as the maximum value of the cache interval as an example, the adjacent difference can be understood as the difference between the maximum values ​​of the cache intervals corresponding to two adjacent indexes in the index table. In this case, the adjacent difference can also be understood as the length of the cache interval corresponding to the two indexes. The adjacent ratio can be understood as the ratio of the maximum values ​​of the cache intervals corresponding to the second index and the third index in the index table, where the second index and the third index are two adjacent indexes in the index table, and the value of the second index is greater than the value of the third index.

[0139] For example, assuming that in an index table, the cache interval corresponding to index 1 is (10, 20], the cache interval corresponding to index 2 is (20, 30], and index 1 and index 2 are two adjacent indexes, in this index table, the adjacent difference is the difference of the maximum values ​​of the cache intervals corresponding to index 1 and index 2, which is 10.

[0140] For example, assuming that in an index table, the cache interval corresponding to index 1 is (10, 20], the cache interval corresponding to index 2 is (20, 40], and index 1 and index 2 are two adjacent indexes, in this index table, the adjacent ratio is the ratio of the maximum values ​​of the cache intervals corresponding to index 2 and index 1, which is 2.

[0141] Among them, if there is an adjacent difference in the first index table that is smaller than the adjacent difference in the second index table, or there is an adjacent ratio in the first index table that is smaller than the adjacent ratio in the second index table, it can be understood that the granularity of the cache interval in the first index table is smaller than the granularity of the cache interval in the second index table, or the step value of the cache interval in the first index table is smaller than the step value of the cache interval in the second index table.

[0142] For example, the following Table 4 and Table 5 are examples:

[0143] Table 4

[0144] Table 5

[0145] Assuming the first index table is Table 4 and the second index table is Table 5, we can calculate that the adjacent difference in the first index table is 2, while the adjacent difference in the second index table is 3. Therefore, we can conclude that the adjacent difference in the first index table is smaller than that in the second index table. In this case, if the index table corresponding to the first index is the first index table, the range of cache data sizes indicated is smaller than that indicated by the second index table.

[0146] For example, the following Table 6 and Table 7 are examples:

[0147] Table 6

[0148] Table 7

[0149] Assuming the first index table is Table 6 and the second index table is Table 7, we can calculate that the adjacent ratio in the first index table is 2, and the adjacent ratio in the second index table is 3. Therefore, it can be concluded that the adjacent ratio in the first index table is smaller than that in the second index table. In this case, if the index table corresponding to the first index is the first index table, the range of cache data sizes indicated is smaller than that indicated by the second index table.

[0150] In the embodiments of the present application, all adjacent differences in the first index table are smaller than the adjacent differences in the second index table, and all adjacent ratios in the first index table are smaller than the adjacent differences in the second index table. It should be noted that in the first index table, only some adjacent differences may be smaller than the adjacent ratios in the second index table, or some adjacent ratios in the first index table may be smaller than the adjacent ratios in the second index table. Related examples can be derived similarly based on the above examples, and the embodiments of the present application will not be further described here.

[0151] Further optionally, the second index table may be one of the tables defined in the current 3GPP R17 standard V17.2.0, such as Table 1 in the above description, and the first index table is a newly defined index table in the embodiment of the present application with a smaller granularity than the second index table.

[0152] Based on the first index table described above, the granularity of the first index table is introduced below:

[0153] In one possible implementation, the adjacent differences in the first index table are the same. The adjacent difference is the difference between the second information corresponding to two adjacent indexes in the index table. Optionally, when the second information is a cache interval, the adjacent difference can be understood as the difference between the maximum values ​​of the cache intervals corresponding to the two adjacent indexes in the index table, or the adjacent difference can also be understood as the length of the cache intervals corresponding to the two indexes. For example, assuming that the cache interval corresponding to index 2 is (2, 4], the length of the cache interval is 2, and correspondingly, the adjacent difference is 2. Since the maximum value of the cache interval corresponding to index 2 is 4, it can be determined that the cache interval corresponding to index 3 is (4, 6].

[0154] In another possible implementation, the adjacent ratios between the second information corresponding to two adjacent indexes in the first index table are the same or the difference between the two adjacent ratios is less than the second threshold. The adjacent ratio is the ratio between the second information corresponding to two adjacent indexes in the index table. Among them, the difference between the two adjacent ratios in the first index table is less than the second threshold, and the second threshold is approximately 0, which can be understood as all adjacent ratios in the first index table are approximately equal. Optionally, when the second information is a cache interval, the adjacent ratio can be understood as the ratio of the maximum values ​​of the cache intervals corresponding to the two adjacent indexes in the index table. For example, assuming that the cache interval corresponding to index 1 is (1, 2], and the cache interval corresponding to index 2 is (2, 4], it can be calculated that the adjacent ratio is 2, and the maximum value of the cache interval corresponding to index 2 is 4, so it can be determined that the cache interval corresponding to index 3 is (4, 8].

[0155] In another possible implementation, the first index table satisfies one or more of the following conditions: Condition 1: The adjacent difference between two indexes in the first index table belonging to the first value range is equal to the first adjacent difference; Condition 2: The adjacent difference between two indexes in the first index table belonging to the second value range is equal to the second adjacent difference; Condition 3: The adjacent ratio between two indexes in the first index table belonging to the third value range is equal to the first adjacent ratio; Condition 4: The adjacent ratio between two indexes in the first index table belonging to the fourth value range is equal to the second adjacent ratio. The first adjacent difference and the second adjacent difference are different, and the first adjacent ratio and the second adjacent ratio are different. Optionally, when the second information is a cache interval, the adjacent difference can be understood as the difference between the maximum values ​​of the cache intervals corresponding to two adjacent indexes in the index table, or the adjacent difference can also be understood as the length of the cache interval corresponding to the two indexes. The adjacent ratio can be understood as the ratio of the maximum values ​​of the cache intervals corresponding to two adjacent indexes in the index table. Further, the value range can be an index range or a cache interval range.

[0156] The following description will be made by taking the case where the first index table satisfies the above conditions 1 and 3 as an example.

[0157] For example, the value range is an index range, the first value range is index 1 to index 3, and the third value range is index 4 to index 10. Index 2 and index 3 both belong to the first value range, the first adjacent difference is 2, assuming that the cache interval corresponding to index 2 is (2, 4], since the maximum value of the cache interval corresponding to index 2 is 4, it can be determined that the cache interval corresponding to index 3 is (4, 6]. Index 4, index 5, and index 6 all belong to the third value range, the first adjacent ratio is 2, assuming that the cache interval corresponding to index 4 is (6, 12], the cache interval corresponding to index 5 is (12, 24], and the maximum value of the cache interval corresponding to index 5 is 24, it can be determined that the cache interval corresponding to index 6 is (24, 48]. The corresponding index table is as follows:

[0158] Table 8

[0159] As another example, the value range is a cache interval range, the first value range is less than 0 to 5, the third value range is greater than or equal to 5 to 20, the first adjacent difference is 1, and the first adjacent ratio is 2. Based on the first value range and the first adjacent difference, the cache range of the second information is (0, 1], (1, 2], (2, 3], (3, 4], (4, 5]; based on the third value range and the first adjacent ratio, the cache range of the second information is determined to be (5, 10], (10, 20], (20, 40], and the corresponding index table is as follows;

[0160] Table 9

[0161] The following description is made by taking the first index table as an example to satisfy the above conditions 1 and 2. For example, the value range is the cache interval range, and the following table 10 is taken as an example:

[0162] Table 10

[0163] Assume that the first index table is Table 8, the first value range is less than or equal to 8, the second value range is greater than 8, the first adjacent difference is 2, and the second adjacent difference is 4. Based on Table 8, it can be seen that the sizes of the cache intervals corresponding to indexes 0 to 3 are all less than or equal to 8. Therefore, in indexes 0 to 3, the difference in the maximum values ​​of the cache intervals corresponding to two adjacent indexes is 2. For example, the maximum value of the cache interval corresponding to index 1 is 2, and the maximum value of the cache interval corresponding to index 2 is 4, and the difference between the two is 2. Based on Table 8, it can be seen that the sizes of the cache intervals corresponding to indexes 4 to 7 are all greater than 8. Therefore, in indexes 4 to 7, the difference in the maximum values ​​of the cache intervals corresponding to two adjacent indexes is 4. For example, the maximum value of the cache interval corresponding to index 5 is 16, and the maximum value of the cache interval corresponding to index 6 is 20, and the difference between the two is 4. When the value range is an index range, the same logic can be obtained based on the above example, and no further details will be given here.

[0164] The following description is made by taking the first index table as an example to satisfy the above conditions 3 and 4. For example, the value range is the cache interval range, and the following table 11 is taken as an example:

[0165] Table 11

[0166] Assume that the first index table is Table 9, the third value range is less than or equal to 8, the fourth value range is greater than 8, the first adjacent ratio is 2, and the second adjacent ratio is 3. Based on Table 9, it can be seen that the sizes of the cache intervals corresponding to indexes 0 to 3 are all less than or equal to 8. Therefore, in indexes 0 to 3, the ratio of the maximum values ​​of the cache intervals corresponding to two adjacent indexes is 2. For example, the maximum value of the cache interval corresponding to index 1 is 2, and the maximum value of the cache interval corresponding to index 2 is 4, and the ratio between the two is 2. Based on Table 9, it can be seen that the sizes of the cache intervals corresponding to indexes 4 to 7 are all greater than 8. Therefore, in indexes 4 to 7, the ratio of the maximum values ​​of the cache intervals corresponding to two adjacent indexes is 4. For example, the maximum value of the cache interval corresponding to index 5 is 36, and the maximum value of the cache interval corresponding to index 6 is 108, and the ratio between the two is 3.

[0167] Optionally, the first value range can also be understood as an index that satisfies the first condition, the second value range can also be understood as an index that satisfies the second condition, the third value range can also be understood as an index that satisfies the third condition, and the fourth value range can also be understood as an index that satisfies the fourth condition. It should be noted that the first condition, second condition, third condition, and fourth condition described above can be any conditions, for example, the first condition is that the index value is greater than a preset threshold, etc., and this embodiment of the application is not limited to this.

[0168] Based on the above description of the first index table, the index and second information included in the first index table are introduced below:

[0169] In a possible implementation, the minimum index in the first index table is 0, the maximum value of the second information corresponding to index 0 is M, and M is 0, or an integer greater than 0. Optionally, the second information is a cache interval.

[0170] For example, assuming that Table 12 is the first index table, it can be seen that the maximum value of the cache interval corresponding to index 0 is 0. If the first index is 0 and the first index comes from the first index table, the cache size corresponding to the LCG indicated by the first index is 0.

[0171] Table 12

[0172] For example, assuming that Table 13 is the first index table, it can be seen that the maximum value of the cache interval corresponding to index 0 is 1. If the first index is 0 and the first index comes from the first index table, the cache size corresponding to the LCG indicated by the first index is less than or equal to 1.

[0173] Table 13

[0174] In another possible implementation, the minimum index in the first index table is N, and N is an integer greater than 0, and the value range of the index included in the second index table is an integer between 0 and N-1. Optionally, the second information is a cache interval. In combination with the above introduction to the first information, this implementation can be combined with the method described above that the first information is the first index, that is, if the first information is greater than the first threshold, the first information indicates that the index table corresponding to the first index is the first index table; if the first information is less than or equal to the first threshold, the first information indicates that the index table corresponding to the first index is the second index table. Among them, the first threshold is N-1. It should be noted that this implementation can also be combined with other methods described in the first information, and the embodiments of the present application are not limited to this.

[0175] For example, assuming that the second index table is Table 14 and the first index table is Table 15:

[0176] Table 14

[0177] Table 15

[0178] The first threshold is set to 3. If the first index is 2, since the first index is less than 3, the cache interval size corresponding to the first index can be determined as (2, 4) through the second index table, i.e., Table 12. If the first index is 6, since the first index is greater than 3, the cache interval size corresponding to the first index can be determined as (10, 12) through the first index table, i.e., Table 13.

[0179] Optionally, the first and second index tables can be combined into a third index table. Assuming the maximum index in the first index table is P, the index values ​​of the third index table range from 0 to P. Assuming that the second index table is Table 14 and the first index table is Table 15, the first and second index tables can be combined into a third index table, as shown in Table 16 below.

[0180] Table 16

[0181] Based on the above introduction to the first index table, in the embodiment of the present application, the first index table can be predefined or configured by the network device. The following mainly introduces how the terminal device determines the first index table:

[0182] In one possible implementation, the terminal device obtains indication information, optionally sent by a network device. Specifically, the network device configures the first index table and sends indication information to the terminal device, where the indication information indicates the first index table. Correspondingly, the terminal device receives the indication information from the network device. The terminal device can determine the first index table based on the indication information. Based on this implementation, the network device can flexibly adjust the content of the first index table based on changes in the current network load, thereby facilitating the terminal device to more accurately indicate the corresponding second information through the first index table and the first index.

[0183] Optionally, the indication information may be a first index table, or the indication information may indicate one or more of the following parameters: the number of indexes in the first index table, the maximum index in the first index table, the minimum index in the first index table, the second information in the first index table, the first range in the first index table, the adjacent differences in the first index table, and the adjacent ratios in the first index table. The first range may be one or more of the first value range, the second value range, the third value range, and the fourth value range described above. The terminal device may determine the first index table based on the one or more parameters indicated in the indication information. The one or more parameters indicated in the indication information are configured by the network device or are predefined.

[0184] Further optionally, the indication information may be one or more parameters in the first index table described above, or the indication information may be some other information, and the terminal device determines the parameters in the first index table based on the other information, and then determines the first index table. Exemplarily, the indication information is a threshold value, and the minimum index in the first index table can be determined based on the threshold value. Specifically, the terminal device determines that the minimum index value in the first index table is the index value corresponding to the cache interval to which the limit in the second index table belongs. Exemplarily, the second information is a cache interval. Assume that the second index table is Table 17.

[0185] Table 17

[0186] The terminal device determines that the threshold value is 3 bytes. In Table 15, the cache interval corresponding to 3 bytes is (2, 4], where the index value corresponding to the cache interval (2, 4] is 2. At this time, it can be determined that the minimum index in the first index table is 2. Further optionally, it is assumed that the maximum index in the first index table is equal to the maximum index in the second index table, and the network device has preset 5 cache intervals, namely (4, 6], (6, 8], (8, 10], (10, 12], and (12, 14], so 2 index tables suitable for the current first index table can be determined from the above 5 cache intervals, so that the first index table can be obtained as 18.

[0187] Table 18

[0188] In one possible implementation, the indication information may not be sent by the network device. Specifically, it may be predefined, or determined by the terminal device sensing the current network environment or other parameters, or sent by other devices. This embodiment of the present application does not limit this.

[0189] 202. The terminal device sends a data format for indicating the first information to the network device. Correspondingly, the network device receives the data format for indicating the first information sent by the terminal device.

[0190] In an embodiment of the present application, the data format may be one of the following formats: Media Access Control Control Element (MAC CE), Service Data Unit (SDU), PDU, Downlink Control Information (DCI), or Radio Resource Control (RRC) signaling. In addition, the data format may also be other formats, which are not limited in the embodiment of the present application. Optionally, the data format includes BSR. Since the first information is used to indicate the first index, the table corresponding to the first index can be determined from at least two index tables through the first information. Based on the method described in the present application, it is beneficial to be able to determine a specific table corresponding to the first index from multiple index tables.

[0191] In order to be able to distinguish the index table corresponding to the index, the embodiment of the present application also proposes an information reporting method, please refer to Figure 8. As shown in Figure 8, the information reporting method includes the following step 801. The execution subject of the method shown in Figure 8 can be a terminal device and a network device, or the execution subject can be a chip in the terminal device or a chip of the network device. Figure 8 uses the terminal device and the network device as an example to illustrate the execution subject of the method, and the embodiment of the present application does not limit the execution subject of the method. Among them:

[0192] 801. A terminal device obtains third information, where the third information is used to indicate an index table of a first index corresponding to a first granularity.

[0193] In an embodiment of the present application, a first index is used to indicate second information of a first granularity, wherein an index table includes a correspondence between the index and the second information. Third information is sent by a network device to a terminal device, and is used to determine an index table corresponding to a first index of the first granularity. The index table corresponding to the first index of the first granularity is one of at least two index tables. Specifically, the first index is an index from one of the at least two index tables, and the second information of the first granularity indicated by the first index is determined by the first index and the index table corresponding to the first index. Optionally, the second information may be the maximum value, minimum value, or median value of an interval within an index table, or the length of the interval, or the maximum value, minimum value, or median value within an index table. The at least two index tables include a first index table and a second index table. It should be noted that the first index table and the second index table are merely examples provided herein. The at least two index tables may also include multiple index tables, such as a third index table. The embodiment of the present application does not limit the number of index tables. The first index table and the second index table will be used as examples in the following text. The embodiment of the present application does not limit the number of index tables included in the at least two index tables. Optionally, one of the at least two index tables is an index table defined in the current 3GPP R17 standard V17.2.0, such as Table 1 in the above description.

[0194] In one possible implementation, the third information may be sent by a network device, or may be predefined, or may be obtained in other ways. The embodiment of the present application does not limit how the terminal device obtains the third information.

[0195] In one possible implementation, the first granularity may be one of the following granularities: LCH, LCG, PDU set, or Qos Flow. Optionally, the first index is an index in the BSR. Further optionally, the first granularity is LCG, and the second information is a cache interval. In this implementation, the first index is used to indicate the cache interval corresponding to the data size of the LCG cache, and the cache interval corresponding to the data size of the LCG cache can be determined by the first index and the table corresponding to the first index. For the format of the BSR, please refer to the description in step 201 above, and this embodiment of the present application will not be elaborated on here.

[0196] In one possible implementation, the third information can indicate the index table of the first index corresponding to the first granularity in the following two ways. It should be noted that the third information can also be implemented in other ways to indicate the index table of the first index corresponding to the first granularity, and the embodiment of the present application does not limit this.

[0197] Method 1: The third information is related to the bitmap. In one implementation method, the third information includes configuration information related to the first granularity, and the information parameters of the configuration information correspond one-to-one to the bits in the bitmap. Optionally, it is implemented by bit mapping. Among them, the configuration information at the first granularity includes multiple information parameters, and the multiple information parameters include a first information parameter and a second information parameter. The bitmap includes a first bit and a second bit. The bitmap corresponding to the first information parameter is the first bit, and the bitmap corresponding to the second information parameter is the second bit. The index table of the first index corresponding to the first information parameter is the first index table, and the index table of the first index corresponding to the second information parameter is the second index table. Optionally, the first bit is 0 and the second bit is 1, or the first bit is 1 and the second bit is 0. Taking LCG as the first granularity, the configuration information includes four information parameters (LCG1, LCG2, LCG3, and LCG4). For example, assuming that the first bit is 0 and the second bit is 1, the bitmap represents 0011. The bitmap includes four bits, which correspond to LCG1, LCG2, LCG3, and LCG4 in order. Among them, the bits corresponding to LCG1 and LCG2 are 1, which is the first bit, and the corresponding index table of the first index is the first index table. The bits corresponding to LCG3 and LCG4 are 0, which is the second bit, and the corresponding index table of the first index is the second index table.

[0198] Method 2: The third information contains configuration information related to the first granularity, and the information parameter of the configuration information is the identifier of the first granularity. The third information indicates the index table of the first index corresponding to the information parameter in the configuration information. Optionally, the third information includes configuration parameters related to the LCG granularity, and the information parameter is the LCG ID. The configuration parameters include (LCG 2, LCG 3), where the network is configured with 8 LCGs, a total of (LCG1 to LCG8). In this implementation, the third information is the LCG configuration and includes the LCG ID, where the index table of the first index corresponding to the LCG ID configured in the third information is the first index table; it can be understood that, except for the LCG ID indicated in the third information, the index table of the first index corresponding to the LCG ID configured in the remaining network is not the first index table, but may be the second index table or other index tables.

[0199] Based on the above introduction to the first information, the following will mainly introduce the index table. It should be noted that the index table is the same as the description in the above step 201. The embodiment of the present application is only briefly described here. The specific implementation method and examples can be found in the description in the above step 201.

[0200] In one possible implementation, at least two index tables include a first index table and a second index table, and the adjacent difference in the first index table is smaller than the adjacent difference in the second index table, or the adjacent ratio in the first index table is smaller than the adjacent ratio in the second index table, the adjacent difference is the difference between the second information corresponding to two adjacent indexes in the index table, and the adjacent ratio is the ratio between the second information corresponding to two adjacent indexes in the index table.

[0201] Wherein, if there are adjacent differences in the first index table that are smaller than those in the second index table, this can be understood as follows: the first index table includes multiple adjacent differences, the second index table includes multiple adjacent differences, and at least one of the multiple adjacent differences in the first index table is smaller than the adjacent differences in the second index table. Similarly, if there are adjacent ratios in the first index table that are smaller than those in the second index table, this can be understood as follows: the first index table includes multiple adjacent ratios, the second index table includes multiple adjacent ratios, and at least one of the multiple adjacent ratios in the first index table is smaller than the adjacent ratios in the second index table.

[0202] Optionally, when the first index is an index in the BSR, the first granularity is LCG, and the second information here can be understood as the maximum value, minimum value, or middle value in the cache interval corresponding to the first index. Taking the second information as the maximum value of the cache interval as an example, the adjacent difference can be understood as the difference between the maximum values ​​of the cache intervals corresponding to two adjacent indexes in the index table. In this case, the adjacent difference can also be understood as the length of the cache interval corresponding to the two indexes. The adjacent ratio can be understood as the ratio of the maximum values ​​of the cache intervals corresponding to the second index and the third index in the index table, where the second index and the third index are two adjacent indexes in the index table, and the value of the second index is greater than the value of the third index.

[0203] In the embodiments of the present application, all adjacent differences in the first index table are smaller than the adjacent differences in the second index table, and all adjacent ratios in the first index table are smaller than the adjacent differences in the second index table. It should be noted that in the first index table, only some adjacent differences may be smaller than the adjacent ratios in the second index table, or some adjacent ratios in the first index table may be smaller than the adjacent ratios in the second index table. Related examples can be derived similarly based on the above examples, and the embodiments of the present application will not be further described here.

[0204] Further optionally, the second index table may be one of the tables defined in the current 3GPP R17 standard V17.2.0, such as Table 1 in the above description, and the first index table is a newly defined index table in the embodiment of the present application with a smaller granularity than the second index table.

[0205] Based on the first index table described above, the granularity of the first index table will be introduced below. The first index table is the same as the description in the above step 201. The embodiment of the present application is only briefly described here. For specific implementation methods and examples, please refer to the description in the above step 201.

[0206] In one possible implementation, the adjacent difference values ​​in the first index table are the same. The adjacent difference value is the difference between the second information corresponding to two adjacent indexes in the index table. Optionally, when the second information is a cache interval, the adjacent difference value can be understood as the difference between the maximum values ​​of the cache intervals corresponding to the two adjacent indexes in the index table, or the adjacent difference value can also be understood as the length of the cache interval corresponding to the two indexes.

[0207] In another possible implementation, the adjacent ratios between the second information corresponding to two adjacent indexes in the first index table are the same or the difference between the two adjacent ratios is less than a second threshold. The adjacent ratio is the ratio between the second information corresponding to two adjacent indexes in the index table. The difference between the two adjacent ratios in the first index table is less than the second threshold, and the second threshold is close to 0, which can be understood as all adjacent ratios in the first index table being approximately equal. Optionally, when the second information is a cache interval, the adjacent ratio can be understood as the ratio of the maximum values ​​of the cache intervals corresponding to the two adjacent indexes in the index table.

[0208] In another possible implementation, the first index table satisfies one or more of the following conditions: Condition 1: The adjacent difference between two indexes in the first index table belonging to the first value range is equal to the first adjacent difference; Condition 2: The adjacent difference between two indexes in the first index table belonging to the second value range is equal to the second adjacent difference; Condition 3: The adjacent ratio between two indexes in the first index table belonging to the third value range is equal to the first adjacent ratio; Condition 4: The adjacent ratio between two indexes in the first index table belonging to the fourth value range is equal to the second adjacent ratio. The first adjacent difference and the second adjacent difference are different, and the first adjacent ratio and the second adjacent ratio are different. Optionally, when the second information is a cache interval, the adjacent difference can be understood as the difference between the maximum values ​​of the cache intervals corresponding to two adjacent indexes in the index table, or the adjacent difference can also be understood as the length of the cache interval corresponding to the two indexes. The adjacent ratio can be understood as the ratio of the maximum values ​​of the cache intervals corresponding to two adjacent indexes in the index table. Further, the value range can be an index range or a cache interval range.

[0209] Optionally, the first value range can also be understood as an index that satisfies the first condition, the second value range can also be understood as an index that satisfies the second condition, the third value range can also be understood as an index that satisfies the third condition, and the fourth value range can also be understood as an index that satisfies the fourth condition. It should be noted that the first condition, second condition, third condition, and fourth condition described above can be any conditions, for example, the first condition is that the index value is greater than a preset threshold, etc., and this embodiment of the application is not limited to this.

[0210] Based on the above description of the first index table, the index and second information included in the first index table are introduced below. The index and second information are the same as those described in the above step 201. The embodiment of the present application is only briefly described here. The specific implementation method and examples can be found in the description in the above step 201. The embodiment of the present application will not be repeated here.

[0211] In a possible implementation, the minimum index in the first index table is 0; the maximum value of the second information corresponding to index 0 is M, where M is 0 or an integer greater than 0.

[0212] In another possible implementation, the minimum index in the first index table is N, where N is an integer greater than 0, and the value range of the indexes included in the second index table is an integer between 0 and N-1.

[0213] Based on the above description of the first index table, in this embodiment of the present application, the first index table can be predefined or configured by the network device. The following will mainly describe how the terminal device determines the first index table. The method for configuring the first index table is the same as that described in step 201 above. This embodiment of the present application only briefly describes it here. For specific implementation methods and examples, please refer to the description of step 201 above. This embodiment of the present application will not be repeated here.

[0214] In one possible implementation, the terminal device obtains indication information, optionally sent by a network device. Specifically, the network device configures the first index table and sends indication information to the terminal device, where the indication information indicates the first index table. Correspondingly, the terminal device receives the indication information from the network device. The terminal device can determine the first index table based on the indication information. Based on this implementation, the network device can flexibly adjust the content of the first index table based on changes in the current network load, thereby facilitating the terminal device to more accurately indicate the corresponding second information through the first index table and the first index.

[0215] Optionally, the indication information may be a first index table, or the indication information may indicate one or more of the following parameters: the number of indexes in the first index table, the maximum index in the first index table, the minimum index in the first index table, the second information in the first index table, the first range in the first index table, the adjacent differences in the first index table, and the adjacent ratios in the first index table. The first range may be one or more of the first value range, the second value range, the third value range, and the fourth value range described above. The terminal device may determine the first index table based on the one or more parameters indicated in the indication information. The one or more parameters indicated in the indication information are configured by the network device or are predefined.

[0216] Further optionally, the indication information may be one or more parameters in the first index table described above, or the indication information may be some other information, and the terminal device determines the parameters in the first index table based on the other information, and then determines the first index table. Exemplarily, the indication information is a threshold value, and the minimum index in the first index table can be determined based on the threshold value. Specifically, the terminal device determines that the minimum index value in the first index table is the index value corresponding to the cache interval to which the limit in the second index table belongs.

[0217] In one possible implementation, the indication information may not be sent by the network device. Specifically, it may be predefined, or determined by the terminal device sensing the current network environment or other parameters, or sent by other devices. This embodiment of the present application does not limit this.

[0218] Based on the method described above, in one possible implementation, the method further includes: the terminal device generates the data format based on the third information, and the data format includes a first index corresponding to the first granularity; the terminal device sends the data format to the network device, and the network device receives the data format accordingly. The data format can be one of the following formats: MAC CE, SDU, PDU, DCI, or RRC signaling. Optionally, the data format includes a BSR. In addition, the data format can also be other formats, which is not limited in this embodiment of the present application.

[0219] In combination with the first index table described above, optionally, if the index table of the first index corresponding to the target granularity is the first index table, and the target information value of the target granularity is less than or equal to the second threshold, then it is not necessary to report it through the data format at present, and wait until the target information value of the target granularity is greater than the third threshold before reporting it through the data format. Further optionally, the target granularity is the target LCG, the target information value is the size of the cached data in the target LCG, and the data format includes BSR. For example, assuming that the index table corresponding to LCG1 is the first index table, the current terminal device needs to report BSR to the network device, but the size of the cached data in LCG1 is less than the second threshold, then the first index corresponding to LCG1 does not need to be included in the reported BSR at this time, and wait until the size of the cached data in LCG1 is greater than the third threshold, and then the terminal device reports the first index corresponding to LCG1 to the network device through the BSR. Based on this implementation method, it is beneficial to reduce the overhead of the data format.

[0220] As the amount of data people need to transmit increases with the times, the cached data size indicated by the index in the BSR reported by terminal devices to network devices is increasing. However, in the index table of the existing standard, a larger index indicates a wider range of cached data sizes. This can lead to irrational resource allocation when the network device schedules resources based on the terminal device's BSR, for example, over-allocating resources to the terminal device. Therefore, the existing technology hopes to address this issue by introducing a new, more fine-grained index table. However, the definition and type of this index table are not yet determined, so how to determine the index table is an urgent problem that needs to be solved.

[0221] In order to enable the index to more accurately indicate the cache size corresponding to the logical channel, an embodiment of the present application proposes an information reporting method, see Figure 9. As shown in Figure 9, the information reporting method includes the following step 901. The execution subject of the method shown in Figure 9 can be a terminal device, or the execution subject can be a chip in the terminal device. Figure 9 uses the terminal device as an example to illustrate the execution subject of the method, and the embodiment of the present application does not limit the execution subject of the method. Among them:

[0222] 901. The terminal device obtains fourth information, where the fourth information is used to indicate a first index table.

[0223] In an embodiment of the present application, the first index table includes a correspondence between an index and a second information. Optionally, the second information can be the maximum value, minimum value, or median value in an interval in an index table, or the length of the interval, or the maximum value, minimum value, or median value in the index table. The fourth information obtained by the terminal device indicates the first index table, and the terminal device can determine the first index table based on the fourth information. The terminal device needs to determine at least two index tables, and the at least two index tables include the first index table.

[0224] In one possible implementation, the fourth information is used to indicate one or more of the following parameters: the number of indexes in the first index table, the maximum index in the first index table, the minimum index in the first index table, the second information in the first index table, the first range in the first index table, the adjacent ratio in the first index table, and the adjacent difference in the first index table. The adjacent difference is the difference between the second information corresponding to two adjacent indexes in the index table. The adjacent ratio is the ratio between the second information corresponding to two adjacent indexes in the index table.

[0225] The terminal device may determine the first index table according to the first rule in the first index table and the parameters indicated in the fourth information.

[0226] The first rule includes the following:

[0227] 1. The adjacent difference values ​​in the first index table are the same. In this case, the fourth information indicates the adjacent difference values ​​in the first index table. The terminal device can determine the first index table based on the first rule and the adjacent difference values ​​indicated in the fourth information.

[0228] 2. The adjacent ratios in the first index table are the same. In this case, the fourth information indicates the adjacent ratio in the first index table. The terminal device may determine the first index table based on the first rule and the adjacent ratio indicated in the fourth information.

[0229] 3. The first index table satisfies one or more of the following conditions: Condition 1: The adjacent difference between two indexes in the first value range in the first index table is equal to the first adjacent difference; Condition 2: The adjacent difference between two indexes in the second value range in the first index table is equal to the second adjacent difference; Condition 3: The adjacent ratio between two indexes in the third value range in the first index table is equal to the first adjacent ratio; Condition 4: The adjacent ratio between two indexes in the fourth value range in the first index table is equal to the second adjacent ratio. The first adjacent difference and the second adjacent difference are different, and the first adjacent ratio and the second adjacent ratio are different.

[0230] In this case, the fourth information indicates one or more of the adjacent differences, adjacent ratios and first ranges in the first index table. It should be supplemented that the adjacent differences can be the first adjacent differences and / or the second adjacent differences, and the adjacent ratios can be the first adjacent ratios and / or the first adjacent ratios. The first range can include one or more of the first value range, the second value range, the third value range and the fourth value range. It should be noted that the value range can be the index range in the first index table or the interval range of the second information. The terminal device can determine the first index table based on the adjacent differences, adjacent ratios and first range in the first index table indicated in the first rule and the fourth information.

[0231] 4. The minimum index in the first index table is 0, and the maximum value of the second information corresponding to index 0 is M, where M is 0 or an integer greater than 0. The fourth information indicates the maximum value M of the second information corresponding to the minimum index in the first index table. The terminal device can determine the first index table based on the first rule and the minimum index corresponding to the second information indicated by the fourth information.

[0232] 5. The minimum index in the first index table is N, where N is an integer greater than 0, and the value range of the indexes included in the second index table is an integer between 0 and N-1. In this case, the fourth information indicates the minimum index N in the first index table. The terminal device can determine the first index table based on the first rule and the minimum index indicated by the fourth information.

[0233] In one possible implementation, the fourth information may be a target parameter, which is used to indicate one or more of the following parameters: the number of indexes in the first index table, the maximum index in the first index table, the minimum index in the first index table, the second information in the first index table, the first range in the first index table, the adjacent ratio in the first index table, and the adjacent difference in the first index table.

[0234] Exemplarily, the target parameter is a threshold value, and the minimum index in the first index table can be determined based on the threshold value. Specifically, the terminal device determines that the minimum index value in the first index table is the index value corresponding to the second information to which the threshold value belongs in the second index table. The target parameter being a threshold value is an example provided in an embodiment of the present application. The target parameter can also be other parameters, which are not limited in this embodiment of the present application.

[0235] In a possible implementation, the terminal device may predefine multiple cache intervals and determine the first index table based on the predefined multiple cache intervals and the fourth information, wherein the number of cache intervals predefined by the terminal device is greater than the number of the first index tables.

[0236] In one possible implementation, the fourth information may be sent by a network device, or may be predefined, or may be determined by the terminal device sensing the current network environment or other parameters, or may be sent by other devices, and this embodiment of the present application does not limit this.

[0237] In one possible implementation, the method further includes, the terminal device determining one or more index tables, and when two index tables are determined, at least two index tables include a first index table and a second index table. It should be noted that the first index table and the second index table are only examples provided in this application. The at least two index tables may also include a third index table and multiple index tables. The embodiment of this application does not limit the number of index tables. The first index table and the second index table will be used as examples in the subsequent content. The embodiment of this application does not limit the number of index tables included in the at least two index tables. Optionally, one of the at least two index tables is one of the tables defined in the current 3GPP R17 standard V17.2.0, such as Table 1 in the above description.

[0238] In one possible implementation, the at least two index tables include a first index table and a second index table. The first index table has an adjacent difference value that is smaller than the adjacent difference value of the second index table, or the first index table has an adjacent ratio value that is smaller than the adjacent ratio value of the second index table. The adjacent difference value is the difference between the second information corresponding to two adjacent indexes in the index table, and the adjacent ratio value is the ratio between the second information corresponding to two adjacent indexes in the index table. This implementation facilitates the index to more accurately indicate the cache size corresponding to the logical channel group.

[0239] Optionally, when the first index is the index indicated in the BSR, the first granularity is LCG, and the second information here can be understood as the maximum value, minimum value or median value in the cache interval corresponding to the first index. Taking the second information as the maximum value of the cache interval as an example, the adjacent difference can be understood as the difference between the maximum values ​​of the cache intervals corresponding to two adjacent indexes in the index table. In this case, the adjacent difference can also be understood as the length of the cache interval corresponding to the two indexes. The adjacent ratio can be understood as the ratio of the maximum values ​​of the cache intervals corresponding to the second index and the third index in the index table, where the second index and the third index are two adjacent indexes in the index table, and the value of the second index is greater than the value of the third index.

[0240] Further optionally, the second index table may be one of the tables defined in the current 3GPP R17 standard V17.2.0, such as Table 1 in the above description, and the first index table is a newly defined index table in the embodiment of the present application with a smaller granularity than the second index table.

[0241] Based on the first index table described above, the granularity of the first index table will be introduced below. The first index table is the same as the description in the above step 201. The embodiment of the present application is only briefly described here. For specific implementation methods and examples, please refer to the description in the above step 201.

[0242] In one possible implementation, the adjacent difference values ​​in the first index table are the same. The adjacent difference value is the difference between the second information corresponding to two adjacent indexes in the index table. Optionally, when the second information is a cache interval, the adjacent difference value can be understood as the difference between the maximum values ​​of the cache intervals corresponding to the two adjacent indexes in the index table, or the adjacent difference value can also be understood as the length of the cache interval corresponding to the two indexes.

[0243] In another possible implementation, the adjacent ratios between the second information corresponding to two adjacent indexes in the first index table are the same or the difference between the two adjacent ratios is less than a second threshold. The adjacent ratio is the ratio between the second information corresponding to two adjacent indexes in the index table.
