1. An operation method of a transmitting terminal in a communication system, the operation method comprising:
receiving, from a base station, a higher layer signaling message including first physical sidelink feedback channel (PSFCH) configuration information indicating a first PSFCH resource region used for transmission or reception of a reception response for sidelink control information (SCI) and second PSFCH configuration information indicating a second PSFCH resource region used for transmission or reception of a hybrid automatic repeat request (HARQ) response for data;
transmitting, to one or more receiving terminals, the SCI including resource allocation information of the data;
transmitting, to the one or more receiving terminals, the data on a physical sidelink shared channel (PSSCH) indicated by the SCI;
performing a monitoring operation on the first PSFCH resource region indicated by the first PSFCH configuration information to receive the reception response for the SCI from the one or more receiving terminals; and
performing a monitoring operation on the second PSFCH resource region indicated by the second PSFCH configuration information to receive the HARQ response for the data from the one or more receiving terminals.
