Classification: CPC H | IPC H

Claim 0:
1. A sidelink (SL) communication method performed by a first terminal in a communication system, the SL communication method comprising:
transmitting, to a second terminal, first sidelink control information (SCI) indicating a first transmission resource and one or more second transmission resources;
transmitting a first redundancy version (RV) of a first transport block (TB) to the second terminal through the first transmission resource; and
when a first configuration indicator is not set, transmitting a second RV of the first TB to the second terminal through a resource among the one or more second transmission resources; and when the first configuration indicator is set, transmitting the second RV of the first TB or a first RV of a second TB other than the first TB to the second terminal through a resource among the one or more second transmission resources,
wherein configuration information including a list of candidate periodicities for the one or more second transmission resources is received from a base station, and when the first configuration indicator is set, the first SCI further includes an index indicating a reservation periodicity of the one or more second transmission resources among the list of candidate periodicities.
