Especially in the future new Radio (NR) communication system, the number of logical channel groups will further increase (from 4 logical channel groups in the LTE system to 8 logical channel groups), this problem will become More prominent.

FIG. 2 is a schematic flowchart of a communication method 200 according to an embodiment of the present application. As shown in FIG. 2, the network device may be an access network device as shown in FIG. 1, or may be a data network as shown in FIG. 1, and the terminal device may be a terminal device as shown in FIG. The following content.

It should be understood that the buffer status report is used to indicate a buffer status of at least one logical channel group of the terminal device.

Optionally, the buffer status report may be carried in the first message.

Optionally, the terminal device may periodically report the buffer status report, or may trigger the reporting of the buffer status report when the buffer status report needs to be reported.

Mode 1, Short BSR; Mode 2, Truncated BSR; Mode 3, Long BSR.

Optionally, the type of the buffer status report may be indicated by a Logical Channel Identity (LC ID) field in a subheader of the MAC PDU.

Optionally, the first logical channel group is a logical channel group with the smallest identifier among the logical channel groups corresponding to the at least two buffer resources to be transmitted.

The first indication information (LCG ID) is used to indicate a logical channel group identified as 3-7.

Optionally, the first logical channel group is a logical channel group with the smallest identifier among the logical channel groups corresponding to the at least two buffer resources to be transmitted.

It should be understood that the size of the first indication information (LCG ID) and the size of the buffer resource of each logical channel group in the total logical channel group are constant, for example, in the LTE communication system, the first indication information (LCG ID) A resource occupying 2 bits, the buffer resources of each of the logical channel groups are the same size, and the buffer resources of one logical channel group can occupy 6 bits of resources; for example, in the NR communication system, the first The indication information (LCG ID) occupies a 3-bit resource, and the buffer resources of each logical channel group in the entire logical channel group have the same size, and the buffer resources of one logical channel group can occupy 6-bit resources.

Optionally, the second indication information may be carried in a subheader of the MAC PDU.

Optionally, after the size of the buffer status report is obtained according to the second indication information, the number of logical channel groups corresponding to the at least two buffer resources to be transmitted may be determined, and the NR communication system is taken as an example, and the buffer status is assumed. The reported size is 21 bits. In this case, the number of logical channel groups corresponding to the at least two buffer resources to be transmitted is m=(21-3)/6=3.

For example, as shown in FIG. 5, when the number n of all logical channel groups is 8, and the logical channel group identified as 2-5 needs to report the buffer status report, the identifier of the first logical channel group may be 2 at this time. The number of logical channel groups corresponding to the at least two buffer resources to be transmitted is m=4, and the first indication information is used to indicate a logical channel group identified as 2-5.
