Abstract

An operation method of a first terminal in a communication system is provided. The method includes transmitting first SCI to a second terminal, the first SCI including one or more information elementsamong information indicating time resource(s) for sidelink communication, information indicating frequency resource(s) for the sidelink communication, information indicating a periodicity of physicalresources for the sidelink communication, and information indicating an MCS for the sidelink communication. Second SCI is transmitted to the second terminal, the second SCI including information foran HARQ feedback operation and information indicating an NDI. The method further includes performing the sidelink communication with the second terminal based on the first SCI and the second SCI associated with the first SCI.
