Abstract

A data indication method includes: transmitting a buffer status report to a network side, the buffer status report containing at least one piece of buffer size information, the buffer size information indicating a buffer size to which a logical channel or a logical channel group corresponds; or transmitting a buffer status report of a variable length to a network side; wherein, the buffer status report of a variable length contains buffer size information on a logical channel group with a buffer size being greater than zero when the buffer status report is triggered or before logical channel data are multiplexed, or contains buffer size information on a logical channel group with a buffer size being greater than zero before logical channel data are multiplexed and being equal to zero after the logical channel data are multiplexed.

Dependent claims

A data indication apparatus, comprising:

a memory that stores a plurality of instructions;
and
a processor coupled to the memory and configured to execute the instructions to:
transmit a buffer status report to a network side, the buffer status report comprising a 3 bit logical channel group (LCG) ID field and a 5 bit buffer size field, wherein the buffer size field indicates a buffer size corresponding to a LCG,
wherein a value range of the buffer size field is defined in the buffer status report table
