[0282] In some embodiments, the terminal reports the data amount of one or more data categories of data in the BSR or DSR.

[0283] In some embodiments, the reported value of the data amount reported by the terminal can be 0, meaning that there is no data amount of the specified data importance level.

[0284] In some embodiments, the reported value of the data amount reported by the terminal can be 0, meaning that there is no data amount of the data category.

[0285] In some embodiments, the terminal can carry an importance indication field of the data in the BSR or DSR to distinguish the importance level of the buffer size of the data.

[0286] In some embodiments, the terminal can carry a category indication field of the data in the BSR or DSR to distinguish the buffer size of the data, to inform the base station that this is the data reporting of which data category.

[0300] In some embodiments, an indication domain can be set to indicate whether there is data left for the LCG to report.

[0301] In some embodiments, for the LCG, the data of the highest priority level is reported first, and if the indication domain is 1, it means that the LCG will report data of a lower priority level.

[0302] In some embodiments, if the indication domain is 0, it means that the data of the LCG is reported, and the reporting of the next LCG is reported.

[0303] In some embodiments, the terminal can report the data volume of a specified data importance level together with the total data volume in the BSR or DSR.

[0304] In some embodiments, a percentage can be reported to indicate the percentage of the total data volume that is the data volume of a specified data importance level.
