In the related art, traffic corresponding to CG may be obtained by piggybacking MAC CE of BSR corresponding to traffic of CG on PUSCH (Physical Uplink Shared Channel ) resource of high priority. In this case, however, there must be enough room on the high priority PUSCH resources to carry the MAC CE of the BSR corresponding to the CG traffic; for PUSCH resources of URLLC (Ultra-Reliable & Low Latency Communication, ultra-low latency communication), the modulation coding rate of PUSCH resources of URLLC is low for the requirement of improving reliability, and if a MAC CE of a very large BSR needs to be carried on PUSCH resources of URLLC, the spectrum utilization rate is greatly reduced.
