1. A method comprising:
allocating, by a first user equipment (UE), a first frequency resource region for a PRS (positioning reference signal) so that the PRS is multiplexed with a feedback signal in a resource region for a physical feedback channel for a direct communication between UEs;
transmitting, by the first UE, allocation information on the first frequency resource region; and
transmitting, by the first UE, the PRS and the feedback signal through the physical feedback channel based on the allocation information,
wherein a size of the first frequency resource region is determined based on a size of a preconfigured frequency resource for the feedback signal and on a multiplexing type, and
wherein the allocation information includes information on the multiplexing type, the size of the first frequency resource region, and a starting frequency of the first frequency resource region.
