Abstract

The present application provides a BSR communication method and terminal device. The communication method includes: the terminal device determines the number of LCGs that currently have buffered data to be reported; when the terminal device determines that only one LCG has buffered data to be reported, determines a BSR format from multiple BSR formats as the first target BSR Format, multiple BSR formats are multiple formats used by terminal equipment to report different BSRs according to the range of uplink buffer data; the terminal equipment sends the target BSR to the access network equipment through the first target BSR format, and the target BSR is used to indicate The amount of upstream buffered data for this LCG. The BSR communication method and terminal device provided by the present application can improve the reporting integrity of the uplink buffer data amount of the LCG.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a communication method, a terminal device and an access network device. Background technique [0002] In a current communication system, such as a long term evolution (long term evolution, LTE) communication system, the number of logical channel groups (logic channel group, LCG) is four. When reporting the uplink buffer data volume of an LCG, the terminal may report the uplink buffer data volume of the LCG in a one-byte buffer status report (buffer status report, BSR) format. [0003] Specifically, 2 bits in this byte are used to indicate which LCG's uplink buffer data volume in the 4 LCG groups is reported, and the other 6 bits are used to indicate the LCG's uplink buffer data volume. [0004] As communication services become more and more diversified, the number of LCGs in the communication network will also increase. This makes it necessary to use more bits to in...
