1. An operation method of a first terminal in a communication system, comprising:
transmitting, by a processor, to a base station, a configuration request message requesting configuration of a sidelink (SL) bandwidth part (BWP) used for sidelink communication between the first terminal and a second terminal;
receiving, by the processor, a configuration information message including configuration information of the SL BWP from the base station;
performing, by the processor, the sidelink communication with the second terminal using one or more SL BWPs indicated by the configuration information; and
in response to determining that reconfiguration of the one or more SL BWPs is necessary, transmitting, by the processor, a reconfiguration request message to the base station,
wherein the configuration information of the SL BWP includes an SL BWP list, and the SL BWP list includes a bandwidth, a subcarrier spacing, resource block (RB) information, and activation information.
