[0170] 3>Report short BSR.

[0171] 1> Otherwise, if the number of padding bits is equal to or greater than the size of the long BSR plus its subheader:

[0172] 2> Report the long BSR of all LCGs that have data available for transmission.

[0173] In some embodiments, if the remaining bits of padding are sufficient to lengthen the BSR, the BSR is lengthened.

[0174] In some embodiments, if the remaining bits of padding are insufficient to lengthen the BSR, a punctured BSR or a short BSR is lengthened.

[0175] In some embodiments, in XR services, data usually consists of multiple flows (QoS flows), and the service volume is very large. At this time, even if there is only one logical channel group, the table of related short BSRs is not enough to carry the BSR reporting data volume of the terminal. And even if a long BSR can be reported; in fact, when reporting a long BSR, because of the huge amount of data, the terminal needs to report a relatively large index, but the larger index also has a problem, that is, it is not fine enough. At this time, the network can only roughly issue authorization, which will cause the terminal to add a large amount of padding when uploading data. Therefore, it is necessary to consider further enhancement of XR services.

[0176] In some embodiments, see Table 1, which shows a new BSR table (corresponding to a format). Different from the original BSR format, the new BSR table is called an improved refined BSR.

[0177] Table 1

[0178] The BTi field is included only in the refined long BSR format. This field is present only when the corresponding LCGi is set to 1; otherwise, it is reserved. If present, this field indicates which buffer size table is used to set the buffer size field for logical channel group i.

[0179] The BTi bit indicates which table the terminal should use when reporting the BSR. If set to 1, the new BSR table is used; if set to 0, the old BSR table is used. The relevant protocols only specify how to report the regular BSR using the refined BSR, but there is no consensus on how to report the padding BSR.

[0180] FIG2a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:

[0181] Step S2101: The network device sends first information to the terminal.

[0182] In some embodiments, the terminal receives first information sent by the network device.

[0183] In some embodiments, the first information is used to instruct the terminal to determine a format type associated with the MAC CE based on the first quantity.

[0184] It should be noted that the format type may be a format corresponding to the table shown in Table 1.

[0185] In some embodiments, the first number is used to indicate the number of padding bits.

[0186] In some embodiments, the MAC CE is used to perform padding buffer status report BSR reporting.

[0187] In some embodiments, the format type includes one of the following:

[0188] The first format includes one of the following:

[0189] First long BSR MAC CE format;

[0190] First long truncated BSR MAC CE format;

[0207] It should be noted that step S2101 is an optional step. For example, the MAC CE type can be determined based on the first quantity based on predetermined protocol rule information. In this case, there is no need to execute S2101.

[0208] Step S2102: The network device sends second information to the terminal.

[0209] In some embodiments, the terminal receives second information sent by the network device.

[0210] In some embodiments, the second information is used to indicate: if the first number is within a first numerical range or a second numerical range, the MAC CE is reported based on the first type of format or the second type of format.

[0211] In some embodiments, the first numerical range is a range greater than or equal to a first value; the first value is the sum of the size of the BSR MAC CE after refinement processing and the size of the corresponding sub-header.

[0212] In some embodiments, the second numerical range is a range smaller than the first value; the first value is the sum of the size of the BSR MAC CE after refinement processing and the size of the corresponding sub-header.

[0213] Step S2103: The terminal determines the format type associated with the media access control MAC control element CE.

[0214] In some embodiments, a format type associated with a medium access control MAC control element CE is determined based on the first number.

[0215] In some embodiments, according to predetermined protocol rule information, the terminal determines the MAC CE type based on the first quantity.

[0216] In some embodiments, the terminal receives first information sent by a network device, and the terminal determines the MAC CE type based on the first quantity.

[0217] In some embodiments, a format type associated with the MAC CE is determined based on a numerical range in which the first number falls.

[0218] In some embodiments, the numerical range is determined based on the size of the BSR MAC CE after refinement processing and the size of the corresponding subheader.

[0219] In some embodiments, the first number is in a first numerical range, and the terminal determines that the format type is a first type format; wherein the value in the first numerical range is greater than or equal to a first value; and the first value is the sum of the size of the BSR MAC CE after refinement processing and the size of the corresponding sub-header.

[0220] In some embodiments, the first number is in a second numerical range, and the terminal determines that the format type is a first type format; wherein the value in the second numerical range is less than the first value; and the first value is the sum of the size of the BSR MAC CE after refinement processing and the size of the corresponding subheader.

[0223] In some embodiments, padding BSR reporting is performed based on the MAC CE of the first type format and the priority of the logical channel.

[0224] In some embodiments, the first number is in a first numerical range or a second numerical range, and the MAC CE reporting based on the first type of format or the second type of format is determined based on a predetermined protocol rule.

[0225] In some embodiments, if the MAC CE is a first truncated BSR MAC CE (Refined Truncated BSR MAC CE), the MAC CE carries a first information field. The first information field may indicate an extended logical channel identifier (eLCID).

[0226] In some embodiments, it is determined that the first number is within a third numerical range, and the terminal determines that the format type is a second type format; wherein, the value within the third numerical range is less than or equal to the second value, or the value within the third numerical range is less than or equal to the first value; the second value is less than the first value, and the first value is the sum of the size of the BSR MAC CE after refinement processing and the size of the corresponding sub-header.

[0227] The following two exemplary embodiments further illustrate the technical solution of the present disclosure:

[0228] Example 1:

[0353] In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, network device side, etc. embodiments, which will not be repeated here.

[0354] In order to better understand the embodiments of the present disclosure, the present disclosure is further described below through some exemplary embodiments:

[0355] In an embodiment of the present disclosure, a method is provided for a terminal to perform padding BSR reporting using a second BSR table.

[0356] In some embodiments, the second BSR table (corresponding to the first type format) is different from the original first type BSR table (corresponding to the second type format). When a terminal reports a BSR according to the second BSR table, it reports the first BSR format (corresponding to the first type format); when a terminal reports a BSR according to the original first type BSR table, it reports the second BSR format (corresponding to the second type format).

[0357] In some embodiments, the first BSR format is a refined BSR or a refined Long BSR, that is, a BSR after refinement.

[0358] In some embodiments, the protocol stipulates or the network notifies the terminal that the second BSR table can be used for padding. Scenario 1 of the BSR report is that the size range of the padding bit is in the first interval, that is, if the size range of the padding bit is in the first interval, the refined BSR can be reported:

[0359] In some embodiments, the values ​​within the first interval (corresponding to the first numerical range) are greater than or equal to the size of the refined Long BSR plus its subheader. In this case, if the number of padding bits is within the first interval, that is, equal to or greater than the refined BSR or the size of the refined Long BSR plus its subheader, the refined BSR may be reported.

[0360] In some embodiments, if at least one logical channel group is configured to use the second BSR table, and its uplink data volume falls within the value range of the second BSR table, then the terminal uses the second BSR table to perform padding BSR reporting, that is, reports the BSR after refined processing.

[0361] In some embodiments, if the number of padding bits is equal to or greater than the size of the refined BSR or the refined Long BSR plus its subheader (refined Long BSR plus its subheader), and if at least one logical channel group is configured to use the second BSR table, and its uplink data volume falls within the value range of the second BSR table, then the terminal uses the second BSR table to report the padding BSR, that is, reports the refined BSR.

[0362] In some embodiments, the protocol stipulates or the network notifies the terminal that the second BSR table can be used for padding. Scenario 1 of the BSR report is that the size range of the padding bit is in the second interval (corresponding to the second numerical range), that is, if the size range of the padding bit is in the second interval, the refined BSR can be reported.

[0363] In some embodiments, the range of the second interval may be smaller than the size of the refined Long BSR plus its subheader or may at least satisfy the buffer size report of an LCG and a 3-byte MAC subheader, that is, larger than 6 bytes.

[0364] In some embodiments, if at least one logical channel group is configured to use the second BSR table and its uplink data volume falls within the value range of the second BSR table, the terminal uses the second BSR table to report a padding BSR. During this process, puncturing can be performed, that is, the BSR of the logical channel group to which the logical channel belongs is prioritized according to the priority of the logical channels, that is, a Refined Truncated BSR MAC CE is reported.

[0365] In some embodiments, if the number of padding bits is in the second range, for example, less than the size of the refined Long BSR plus its subheader or can at least meet the Buffer size report of an LCG and a 3-byte MAC subheader, that is, greater than 6 bytes, and at least one logical channel group is configured to use the second BSR table, and its uplink data volume falls within the value range of the second BSR table, then the terminal uses the second BSR table to report padding BSR (padding), and can report the Refined Truncated BSR MAC CE.

[0366] In some embodiments, it can be agreed upon by protocol or the network can notify the terminal whether the terminal uses the second BSR table to report padding BSR (padding) within the first interval or the second interval, or whether the terminal can use the first BSR table to report padding BSR (padding).

[0367] In some embodiments, a new eLCID is added to indicate the Refined Truncated BSR MAC CE.

[0368] In some embodiments, the protocol stipulates or the network notifies the terminal that if the size of the padding bit is in the third interval (corresponding to the third numerical range), the first BSR table can also be used to report the padding BSR (padding); that is, Long BSR, Long Truncated BSR reporting or Short BSR, Short Truncated BSR reporting can be reported according to the size of the padding bit.

[0369] In some embodiments, the size of the value in the third interval is smaller than the lower limit of the second interval, for example, if it is smaller than 6 bytes, the first BSR table may be used for padding BSR reporting.

[0370] In some embodiments, the size of the value in the third interval is smaller than the lower limit of the first interval. For example, if it is smaller than the size of the refined Long BSR plus its subheader, then the first BSR table can also be used for padding BSR reporting.

[0371] In some embodiments, if the number of padding bits is within the third interval, for example, the size is smaller than the lower limit of the first interval, for example, if it is smaller than the size of the refined Long BSR plus its subheader, if only one logical channel group has data volume to be reported, and the second BSR table is configured to be used, and its uplink data volume falls outside the value range of the second BSR table, then Long BSR, Long Truncated BSR reporting or Short BSR, Short Truncated BSR reporting can also be performed (a preferred embodiment may be to use Long Truncated BSR reporting). For other situations, for example, if there is a logical channel group that has data volume to be reported, and the second BSR table is configured to be used, and its uplink data volume falls within the value range of the second BSR table, then Refined Truncated BSR MAC CE reporting can still be used. For example, if at least two logical channel groups have data volumes to report, and at least one logical channel group is configured to use the second BSR table, and its uplink data volume falls within the value range of the second BSR table, then Refined Truncated BSR MAC CE can still be used for reporting.
