Abstract
A method of a first user equipment (UE) to transmit information related to a conflict of a reserved resource in a wireless communication system comprises receiving, from a second UE, a first sidelink control information (SCI) related to a first reserved resource for a physical sidelink shared channel (PSSCH), receiving, from a third UE, a second SCI related to a second reserved resource for a PSSCH, determining a conflict between the first reserved resource and the second reserved resource, and transmitting, to the second UE or the third UE, information related to the conflict.

- determining a conflict of the first reserved resource and the second reserved resource;
- and
- transmitting, to the second UE or the third UE, information related to the conflict,
