Detailed Description

The present application is described in further detail below with reference to the accompanying drawings and examples.

In the related art, the BSR is one of the common control units MAC CE in the control layer MAC, which is used to notify the base station of the data to be sent in the current buffer area of the UE, and the base station may allocate uplink resources to the UE according to the data amount buffered by the UE reported by the BSR. In the related art, the BSR types in 4 are respectively Short BSR, short truncated BSR, long BSR and Long truncated BSR, but only 2 reporting formats are provided, fig. 1 is a schematic diagram of a Buffer Size field of 5bit format in the embodiment of the present application, as shown in fig. 1, and is applicable to Short BSR and Short truncated BSR; fig. 2 is a schematic diagram of a Buffer Size field of 8 bits in the embodiment of the present application, as shown in fig. 2, and is applicable to Long BSR and Long truncated BSR. Wherein, the maximum Buffer data corresponding to the Buffer Size is >150000 bytes (byte) when the Buffer Size is 5 bits, the maximum Buffer data corresponding to the Buffer Size is >81338368 bytes when the Buffer Size is 8 bits, and the table 1 is the actual Buffer Size corresponding to each Buffer Size Index when the Buffer Size is 5 bits, as shown in the table 1:

TABLE 1

In the related art, the mapping of Buffer Size adopts an index-like mapping manner, that is, when the Buffer Size is smaller, there are multiple levels of mapping, and when the Buffer Size is larger, only a few levels are available for selection. And compared with LTE, the short BSR of NR and Buffer Size of short truncated BSR are 1bit less, and half of the grades are lost. Meanwhile, the Buffer Size can be closest to the level in a larger direction, so that the indicated Buffer information is larger, and the wireless resource is wasted.

On the other hand, in the related art, in the BSR reporting scheme, buffer Size Index of each class corresponds to a unit of byte, and the specific value is shown in fig. 3, and fig. 3 shows that Buffer Size Index of each class corresponds to a unit of byt in the BSR according to the embodiment of the present applicatione, a graph of the graph. After fitting, it can be seen that the curve is shaped as y= a e ^bx More levels index can be mapped when the actual buffer size is smaller, and the corresponding levels are smaller when the buffer size is larger. However, the influence of the user service type on the buffer size of the buffer area is relatively large, and a considerable quantization error exists when index is used for mapping to a fixed buffer size.

Based on this, in various embodiments of the present application, the range of the reference is adjusted by taking the buffer size range of the terminal in the first period as the ratio of the reference, so that the buffer size range of the closest level is more accurate when the first information in the BSR indicates to be taken in the larger direction, and the buffer size range where no indication exists is larger, thereby not wasting wireless resources and improving the utilization rate of wireless resources and the system capacity. The embodiment of the application provides a BSR processing method, which is applied to a first device, as shown in fig. 4, fig. 4 is a flowchart of a BSR-based information processing method in the embodiment of the application, including:

step 401: acquiring N BSRs of a terminal in a first period, wherein N is an integer greater than or equal to 1, the BSRs comprise first information, and the first information indicates a cache size range of the terminal;

step 402: determining a proportion of a buffer size range of the terminal in the first period as a reference based on N BSRs, wherein the reference is the highest-level buffer size range which is allowed to be reported by the terminal;

step 403: and adjusting the range of the reference according to the proportion or maintaining the range of the reference.

It should be noted that the first device may be a network device or a terminal; the network device comprises a base station; the main body executed in the steps 401 to 403 may be determined according to the actual situation, which is not limited herein, and the main body executed in the steps 401 to 403 may be a terminal or a base station.

In step 401, the first period may be a preset period of configuration; the preset period may be determined according to an actual situation, which is not limited herein, and in an actual application, the preset period may be referred to as a BSR adjustment period.

In step 402, the reference may be determined according to practical situations, which is not limited herein. The reference may be a reference negotiated by the first device and the second device; in the case that the first device is a base station, the second device is a terminal; in the case that the first device is a terminal, the second device is a base station; in practical applications, the negotiated reference may also be referred to as an initial value, which may be understood as a buffer size corresponding to the initial maximum index.

The reference is a highest-level buffer size range that the terminal allows to report, and for convenience of understanding, the highest level may be 31, and the highest-level buffer size range may be greater than 150000byte, which is described in conjunction with table one above; i.e. the benchmark may be greater than 150000 bytes for a cache size range corresponding to a highest level of 31.

Determining, based on the N BSR, a proportion of the buffer size range of the terminal in the first period as a reference may be a number of times based on the N BSR determining the buffer size range of the terminal in the first period as a reference; and determining the proportion according to the times and the N times. The determining of the ratio according to the number of times and the N times may specifically be that the number of times is compared with the N times to obtain the ratio. For convenience of understanding, the number of times that the buffer size range of the terminal is used as a reference in the first period may be understood as the number of times of the maximum BSR of the terminal in the first period; the N times may be understood as the total number of terminal BSRs in the first period; the proportion may be referred to as the proportion of the maximum level BSR that occurs during the first period; the ratio of occurrence of the maximum level BSR in the first period = the number of times the terminal has maximum level BSR in the first period/the total number of times the terminal has reported BSR in the first period.

In step 403, adjusting the range of the reference according to the ratio may be increasing or decreasing the range of the reference according to the ratio; maintaining the range of the reference according to the ratio may be understood as not adjusting the range of the reference according to the ratio; as an example, in the case where the ratio is equal to a threshold value, the range of the reference is not adjusted; narrowing the range of the reference if the ratio is greater than the threshold; in the case where the ratio is smaller than the threshold value, the range of the reference is increased.

In practical application, the reference may be a buffer size range corresponding to a highest level in a certain BSR table in at least one pre-configured BSR table; the specific number of the at least one BSR table may be determined according to actual situations, which is not limited herein, and as an example, the specific number of the at least one BSR table may be 3-5; each BSR table in the at least one BSR table comprises a corresponding relation between a BSR Index and a Buffer size; the BSR Index may be understood as a level, and the Buffer size corresponding to the BSR Index may be understood as a Buffer size range corresponding to the level; and the reference is Buffer size corresponding to the maximum value of the BSR Index.

In this embodiment of the present application, the buffer size range of the terminal in the first period is used as the reference ratio, and the reference range is adjusted, so that the buffer size range in which the first information in the BSR indicates to take the closest level to the larger direction is more accurate, and the buffer size range in which no indication exists is larger, thereby not wasting radio resources and improving the utilization rate of radio resources and the system capacity.

In an embodiment, the first information includes a first identifier, where the first identifier characterizes a cache size range of the terminal, the first identifier is an identifier in a first relationship, the first relationship includes a correspondence between at least one identifier and the cache size range of the terminal, the reference is a cache size range of a highest level in the first relationship, and each correspondence corresponds to a level;

and generating a second relation by using the first relation, wherein the second relation comprises at least one corresponding relation between the identifier and the buffer size range of the terminal, the buffer size range of the highest level in the second relation is an adjusted standard, and at least the corresponding relation between the identifier and the buffer size range of the highest level is different from the corresponding relation between the identifier and the buffer size range of the highest level in the first relation.

In this embodiment of the present application, the first relationship may be a relationship in a preset table; the preset table comprises a plurality of corresponding relations; each of the plurality of relationships corresponds to a level; each relation comprises a corresponding relation between at least one identifier and a buffer size range of the terminal; the preset table may be a table selected from a pre-configured table; the preset table may be determined according to actual situations, which is not limited herein. As an example, the preset table may be a BSR table; the BSR table comprises corresponding relations of Buffer Size Index with different grades and BS vale; wherein Buffer Size Index is understood to be a label, abbreviated Index; the BS vale can be understood as a terminal buffer size range. For easy understanding, the BSR table may be understood by combining table one, where Index corresponds to BS vale, and there are 0-31 levels of correspondence, where the buffer size range of the highest level is that BS vale corresponding to Index of 31 is greater than 150000 bits, that is, the reference may be that BS vale corresponding to Index of 31 is greater than 150000 bits.

Generating a second relationship using the first relationship may be understood as adjusting a cache size range of a highest level in the first relationship to generate the second relationship.

The adjusted reference may be understood as a reference obtained by expanding or shrinking the range of the reference previously negotiated. For ease of understanding, the example herein assumes that BS vale corresponding to Index of 31 is greater than 150000 bits; the adjusted reference may be greater than 140000 bits for BS vale corresponding to Index 31 or greater than 160000 bits for BS vale corresponding to Index 31.

In an embodiment, the method further comprises:

or,

In this embodiment, the preset service type may be determined according to an actual situation, which is not limited herein. As an example, the preset traffic type may include a dominant traffic type. The dominant traffic type may be video, which may be user uploaded video or live video.

As an example, in the case where the type of service of the terminal is a video service type, the cumulative distribution function CDF of the gaussian distribution generated based on the range distribution probability of the buffer size of the terminal BSR may be a CDF of the gaussian distribution generated based on the amount of data transmitted by the terminal in a unit time, after forming the distribution probability-related parameter, according to the distribution probability-related parameter.

In the case that the type of the service of the terminal is not a video service type, the first relationship may be generated based on an exponential function; the exponential function may be y= a e ^bx Wherein a and b may be specifically determined according to practical situations, and are not limited herein.

In an embodiment, the method further comprises:

or,

In this embodiment of the present application, the threshold may be determined according to actual situations, which is not limited herein. As an example, the threshold may be a configured threshold, abbreviated as threshold.

Under the condition that the buffer size range of the terminal in the first period is between the preset buffer range and the reference range, the fact that more levels index can be corresponding when the real buffer size is smaller in practical application is mainly considered, and the corresponding levels are less when the buffer size is larger. For ease of understanding, the example is illustrated herein with reference to table 1 and fig. 3, where the buffer size is relatively small, e.g., between 0-1446 bytes, the corresponding level index is 0-16, and the number of level index is 17 in total; in the case where the buffer size is relatively large, for example, the buffer size is greater than 1446byte, the corresponding class index is 17-31, and the number of class index is 15 in total; obviously, buffer size is smaller, and corresponding level index is more; the buffer size is larger, the corresponding level index is less, and the buffer size mapped to the fixed buffer size by adopting index has a considerable quantization error, so that the buffer size is adjusted to be 17-31 corresponding to the level index when the buffer size is larger than 1446byte.

The preset cache range may be determined according to practical situations, which is not limited herein. As an example, the preset cache range may be >1446byte for cache data.

In practical applications, when the ratio is greater than the threshold, determining to expand the range of the reference may be understood as that the ratio of the N BSR as the reference exceeds the threshold, which indicates that the buffer size corresponding to the current maximum level is smaller, and that the buffer size needs to be raised, that is, the range of the reference is expanded. For ease of understanding, the example herein illustrates that, assuming that the range of the benchmark is between 107669 and 150000 bytes for the highest level 30 of buffered data, the ratio of buffered data between 107669 and 150000 bytes in the N BSR is greater than the threshold, indicating that the range of buffered data is smaller in 107669 and 150000 bytes, the range of buffered data 107669 and 150000 bytes needs to be expanded, and therefore 107669 can be scaled down and/or 150000 can be scaled up, i.e. the range of the benchmark is expanded; the proportion of the buffer data between 107669 and 150000 bytes in the BSR for N times is smaller than a threshold, which indicates that the buffer data is bigger in the range of 107669 to 150000 bytes, and the range of the buffer data 107669 to 150000 bytes needs to be reduced, so that 107669 can be enlarged and/or 150000 can be reduced, namely the range of the standard is reduced; assuming that the range of the reference is that the highest level 31 cache data is >150000byte, and the proportion of the cache data >150000byte in the N BSR is greater than the threshold, which indicates that the range of the cache data >150000byte is smaller, the range of the cache data >150000byte needs to be expanded, for example, the range of the cache data >150000byte is expanded to the cache data >140000byte, namely, the range of the reference is expanded; the ratio of the buffer data >150000byte in the N BSR is smaller than the threshold, which indicates that the range of the buffer data >150000byte is larger, and the buffer data >150000byte range needs to be narrowed, for example, the buffer data >150000byte is narrowed to the buffer data >160000byte, i.e. the range of the standard is narrowed. In connection with fig. 3, it can be understood that the table in fig. 3 is left-shifted and right-shifted to expand or contract its indication range.

In an embodiment, the first information includes a first identifier, where the first identifier characterizes a cache size range of the terminal, the first identifier is an identifier in a first relationship, the first relationship includes at least one correspondence between the identifier and the cache size range of the terminal, and each correspondence corresponds to a level;

In this embodiment, the range distribution probability of the buffer size of the terminal BSR may be determined based on a range distribution probability parameter of the buffer size of the terminal BSR, and as an example, the data amount sent by the terminal in a unit time may be counted to form a distribution probability parameter, and then the range distribution probability of the buffer size of the terminal BSR is determined according to the distribution probability parameter.

In an embodiment, the method further comprises:

In this embodiment, the second information indicates the range of the adjusted reference may be understood as notifying the opposite end of the range of the adjusted reference, so that the opposite end performs a corresponding operation based on the range of the adjusted reference.

In an embodiment, the method further comprises:

negotiating the reference with the second device.

It should be noted that, negotiating the reference with the second device may be determined by sending a request, where the second device may be a network device or a terminal, for example, in the case where the first device is a network device, the second device is a terminal, the reference may be default, and the network device may send the default reference to the terminal to confirm through the request, and then correspondingly adjust according to a result after the confirmation of the terminal; in the case that the first device is a terminal, the second device may be a network device, and the reference may be that the terminal sends a first request to the network device, where the first request is used for configuring the reference by the network device, and the network device configures the reference for the terminal according to the first request sent by the terminal.

In this embodiment, a generation process of buffer size index and buffer size curves is adopted, and the curve is formed as y= a e in consideration of the related protocol ^bx In some services, such as live video or uploading video, the user buffer buffers video frames, and the size of the video frames, due to the resolution and color depth and encoder limitations, fluctuates around a desired valueSamples that are large from the reference value have a low probability of occurrence. The video frame size often accords with gaussian distribution, but the exponential function is very different, and at this time, the exponential function has a relatively large quantization error, and the corresponding relationship between buffer size index and buffer size can be more accurate according to cdf regeneration.

Correspondingly, the embodiment of the application also provides a BSR-based information processing method, as shown in fig. 5, fig. 5 is a flowchart of another BSR-based information processing method in the embodiment of the application, which is applied to a second device and includes:

step 501: receiving second information sent by the first equipment, wherein the second information indicates the range of the adjusted reference;

wherein, in case the first device comprises a network device, the second device comprises the terminal; alternatively, in the case where the first device comprises the terminal, the second device comprises a network device.

In this embodiment, the range of the adjusted reference may be understood as a range of the adjusted reference obtained after the range of the reference is adjusted; the standard is the highest-level buffer size range of the BSR which is allowed to be reported by the terminal; the reference may be determined according to practical situations, and is not limited herein. The reference may be a negotiated reference; in practical applications, the negotiated reference may also be referred to as an initial value, which may be understood as a buffer size corresponding to the initial maximum index.

The second relationship may be generated by adjusting the content in the first relationship using the second information according to the second information and the first relationship. As an example, the content in the first relationship is adjusted by using the second information, and the second relationship may be generated by adjusting the reference before adjustment in the first relationship by using the range of the reference after adjustment in the second information.

As an example, the first relationship may be a relationship in a preset table; the preset table comprises a plurality of corresponding relations; each of the plurality of relationships corresponds to a level; each relation comprises a corresponding relation between at least one identifier and a buffer size range of the terminal; the preset table may be a table selected from a pre-configured table; the preset table may be determined according to actual situations, which is not limited herein. As an example, the preset table may be a BSR table; the BSR table comprises corresponding relations of Buffer Size Index with different grades and BS vale; wherein Buffer Size Index is understood to be a label, abbreviated Index; the BS vale can be understood as a terminal buffer size range. For easy understanding, the BSR table may be understood in combination with table one, where Index corresponds to BS vale, and there are 0-31 levels of correspondence, where the first relationship may be a correspondence that includes at least one BS vale corresponding to the identifier 31 being greater than 150000 bits; the pre-adjustment reference may be the highest level buffer size ranging from Index 31 to BS vale greater than 150000 bits.

The second information indicates a range of the adjusted reference, and the adjusted reference may be understood as a reference obtained by expanding or shrinking a range of the reference before adjustment. For ease of understanding, the example herein assumes that BS vale corresponding to Index 31 is greater than 150000 bits; the adjusted reference may be greater than 140000 bits for BS vale corresponding to Index 31 or greater than 160000 bits for BS vale corresponding to Index 31.

In practical applications, the range of the adjusted reference in the second information is used to adjust the reference before adjustment in the first relationship, so that the second relationship can be generated by adjusting the range of BS vale corresponding to Index 31 to the range of BS vale greater than 140000bit, corresponding to Index 31 to the range of BS vale corresponding to Index 31 to the range of BS value greater than 150000bit, and further correspondingly adjusting the corresponding relationship between other identifiers and the buffer size range of the terminal.

In an embodiment, the method further comprises:

The first function may be a gaussian distributed CDF generated based on a range distribution probability of the buffer size of the terminal BSR, and specifically may be a gaussian distributed CDF generated based on a data amount transmitted by the terminal in a unit time, after forming a distribution probability related parameter, according to the distribution probability related parameter.

Generating a third relationship using the second information and the first function may generate a third relationship for the CDF using the range of the adjusted reference and the gaussian distribution in the second information.

The third relationship may be a relationship in a regenerated table; the regeneration table comprises a plurality of corresponding relations; each of the plurality of relationships corresponds to a level; each relation comprises a corresponding relation between at least one identifier and a buffer size range of the terminal; the re-generation table may be updated for a table selected from a pre-configured table according to the second information and the first function; the preconfigured table may be determined according to practical situations, and is not limited herein. As an example, the preconfigured table may be a BSR table; the BSR table comprises corresponding relations of Buffer Size Index with different grades and BS vale; wherein Buffer Size Index is understood to be a label, abbreviated Index; the BS vale can be understood as a terminal buffer size range. For easy understanding, the BSR table may be understood by combining table one, where Index corresponds to BS vale, and there are 0-31 levels of correspondence, where the buffer size range of the highest level is that BS vale corresponding to Index of 31 is greater than 150000 bits, that is, the reference may be that BS vale corresponding to Index of 31 is greater than 150000 bits.

In practical application, on one hand, multiple sets of BSR tables may be configured in advance on the terminal and the network side according to CDFs with different probability distributions, and then the network side or the terminal side switches between the multiple sets of tables.

In an embodiment, the method further comprises:

negotiating a pre-adjustment reference with the first device.

It should be noted that, the reference before negotiating with the first device may be determined by sending a request, and the second device may be a network device or a terminal, for example, in the case that the first device is a network device, the second device is a terminal, the reference may be default, and the network device may send the default reference to the terminal for confirmation through the request, and then perform corresponding adjustment according to the result after the confirmation of the terminal; in the case that the first device is a terminal, the second device may be a network device, the reference may be a terminal sending a reference to-be-configured request, and the network device performs configuration according to the reference to-be-configured request.

In practical application, as an example, the BSR-based information processing method may be specifically a BSR-based reporting and configuration method; as an example, in case the first device may be a network device, the second device may be a terminal; in the case that the first device may be a terminal, the second device may be a network device; the reporting and configuring method of the BSR mainly comprises two parts of determining buffer size corresponding to the maximum index of the BSR and generating an index and buffer size curve.

The first part is to determine the buffer size corresponding to the maximum level of the BSR, and because the field length used to indicate the buffer size in the related protocol is determined, on the premise of not changing the length of the buffer size field, the method can be implemented by changing the mapping range of the method, that is, changing the actual buffer size value corresponding to the current maximum indication index, and the specific process is shown in fig. 6, and fig. 6 is a flow chart of determining the buffer size corresponding to the maximum level of the BSR in the embodiment of the application. The method comprises the following steps:

the first step: the network side configures parameters such as a BSR adjustment period, a BSR reporting frequency threshold and the like. The buffer size corresponding to the buffer level can be adjusted only once in one period; the BSR reporting number threshold is the number of minimum regular or periodic BSRs required to make a buffer size adjustment.

And a second step of: the network side negotiates with the terminal to determine a real buffer size corresponding to the initial maximum index, and the real buffer size is used as an initial value.

And a third step of: the terminal starts communication by using an initial value, reports the BSR, and counts the number and the proportion of the maximum index in the reported BSR when the number of times of reporting the BSR and the current reporting statistics period time exceed a threshold; the proportion calculating method comprises the following steps: the occurrence ratio of the maximum level BSR in the current statistics period=the number of times the terminal reports the maximum level BSR in the current statistics period/the total number of times the terminal reports the BSR in the current statistics period.

Fourth step: when the ratio of the maximum level BSR exceeds the threshold, the buffer size corresponding to the current maximum level is smaller, and the flow of raising the upper limit of the maximum buffer size is triggered. Otherwise, the process of lowering the maximum buffer size upper limit is triggered by the smaller buffer size corresponding to the maximum level of the current configuration.

Fifth step: and informing the opposite end of the generated maximum buffer size upper limit, and regenerating the buffer size corresponding to each rank buffer size index. A plurality of different corresponding tables of buffer size index and buffer size can be generated in advance and configured to the opposite-end table number; the left shift and right shift operation can be simply performed on the existing table to expand or reduce the indication range.

In the above steps, except that the BSR reporting is completed by the terminal, the rest steps may occur at the network side or the terminal side, and the opposite terminal may be notified in the fifth step.

In this embodiment, the network side and the terminal side dynamically configure and adjust the buffer size upper limit corresponding to the maximum BSR level according to the ratio of whether the BSR reported by the terminal is the maximum.

The second part is the generation of buffer size index and buffer size curves, which are in the form of y= a e in the related protocol as mentioned above ^bx In some services, such as live video or uploading video, the user buffer buffers video frames, and the size of the video frames, due to the limitations of resolution and color depth and encoder, fluctuates around a desired value, and the probability of occurrence of samples deviating from the reference value is low. The size of the video frames tends to conform to a gaussian distribution, which is tiredThe score distribution function cdf is shown in formula (1):

it can be seen that the difference from the exponential function is large, and at this time, the exponential function scheme has a relatively large quantization error, and the corresponding relationship between buffer size index and buffer size can be regenerated more accurately according to cdf.

The generation process of buffer size index and buffer size curves can comprise the following three steps:

the first step: the probability distribution type of the BSR is determined. There may be two embodiments, where in the first embodiment, the terminal or the network side counts the data amount sent by the terminal in a unit time, and then notifies the opposite terminal to change the BSR distribution curve according to the distribution related parameter after forming the distribution related parameter. In a second embodiment, the network side or the terminal side forms a distribution related parameter according to the current service type of the terminal (such as VR, video, foam, etc., the service type can be notified by an application layer or a core network), combines information provided by the application layer or the core network (such as file size, code rate, playing time, etc.), and notifies the opposite terminal to change the BSR distribution curve according to the distribution related parameter.

And a second step of: after receiving the distribution related parameters, determining a specific BSR table (BSR table for short) according to the distribution related parameters, wherein the two embodiments are two, namely, a plurality of BSR tables are configured according to CDFs with different probability distributions in advance on a terminal and a network side, and then the network side or the terminal side switches among the plurality of BSR tables; the network side or the terminal side sends a request, and the other side sends an acknowledgement. The second scheme is that data of a table are generated in real time, the adopted method is that a network side or a terminal side sends distribution related parameters to an opposite terminal, wherein the distribution related parameters comprise parameters such as probability distribution types, matrix functions, expectations, variances, various coefficients corresponding to CDF functions and the like; after the opposite terminal determines the CDF according to the distribution related parameters, it can determine what Buffer size is corresponding to each level according to the bit numbers of Buffer size in short BSR and long BSR, such as 5bit and 8 bit. If the CDF difference value corresponding to each rank is 1/8=0.125, i.e. 0.125,0.25,0.375, … …,1 when the rank is 8, the corresponding Buffer size upper limit can be determined by calculating the corresponding CDF value.

The steps of adjusting the maximum values in this and the previous schemes may be independent of each other or may be applied in combination with each other.

In this embodiment, the network side and the terminal side determine a cumulative distribution function according to the BSR reported by the terminal and the current dominant service type or self statistics; and if the current service type is not dominant, generating a cumulative distribution function according to the reported BSR. And regenerates the buffer size corresponding to each buffer size index according to the cumulative distribution function and informs the opposite terminal of use.

Therefore, in the fifth step of the above scheme, a cumulative distribution function is generated according to the probability distribution of the BSR reported by the terminal, and the buffer size corresponding to each buffer size index is regenerated according to the cumulative distribution function generated by each level, so that the BSR reporting is more accurate.

According to the embodiment of the application, the network side and the terminal side dynamically configure and adjust the buffer size upper limit corresponding to the maximum BSR level according to the ratio of whether the BSR reported by the terminal is the maximum or not; and the network side and the terminal side generate cumulative distribution functions according to the BSR reported by the terminal, and regenerate the buffer size corresponding to each buffer size index, and notify the opposite terminal. Compared with the traditional scheme, the method can enable the terminal to report the real buffer size in the buffer area of the terminal closer to the BSR by adjusting the buffer size upper limit corresponding to the maximum buffer size index and the buffer size corresponding to buffer size index of each grade, so that the resource allocation is closer to the actual requirement of the terminal. And infinite resources are saved, and the maximum number of users supportable by the system is improved.
