1. A message transmission method, applied to a terminal and comprising:
transmitting a first discovery message in a sidelink (SL), wherein
the first discovery message is transmitted between an upper layer and a MAC layer through a logical channel, and a priority of the first discovery message is determined based on the logical channel and/or a corresponding bearer;
wherein in a case that the first discovery message is transmitted between the upper layer and the MAC layer through a control logical channel, the first discovery message is transmitted between the upper layer and the MAC layer through an signaling radio bearer (SRB); the first discovery message and a first message in the SL are transmitted through at least two different SRBs, the first message in the SL comprises RRC signaling in the SL and a PC5 signaling message in the SL, the first discovery message, the RRC signaling in the SL and the PC5 signaling message in the SL have a same priority.
