the other is uplink/downlink communication mode between terminal and LTE base station, in which the air interface between terminal and base station is called Uu interface. The sidelink communication mode further includes two sending modes, wherein the sidelink sending mode 3 (Mode 3) is a base station scheduling resource allocation mode, and the sidelink sending mode 4 (Mode 4) is a terminal autonomous resource selection mode.
