1. A method performed by a terminal device or by a chip of the terminal device, comprising:
sending a first buffer status report (BSR), wherein the first BSR comprises first buffer status information of at least a first sidelink (SL) logical channel group (LCG), wherein the first SL LCG satisfies a first condition, and wherein the first condition is that the first SL LCG comprises a first SL logical channel (LCH) containing first SL data and that a first priority of the first SL LCH is greater than a first threshold,
wherein a first multiplexing priority of the first BSR is higher than a third multiplexing priority of a third BSR, wherein the third BSR comprises third buffer status information of at least a third LCG, the third LCG comprising at least a third LCH containing uplink (UL) data, wherein the third multiplexing priority of the third BSR is higher than a second multiplexing priority of a second BSR, wherein the second BSR comprises second buffer status information of at least a second SL LCG, wherein a second priority of a second SL LCH is lower than the first threshold, and wherein the second priority of the second SL LCH is a highest priority in one or more priorities corresponding to one or more SL LCHs containing second SL data and belonging to the second SL LCG.
