Classification: CPC H | IPC H

Claim 5:
6. A sidelink (SL) communication method performed by a second terminal in a communication system, the SL communication method comprising:
receiving, from a first terminal, first sidelink control information (SCI) indicating a first transmission resource and one or more second transmission resources;
receiving a first redundancy version (RV) of a first transport block (TB) from the first terminal through the first transmission resource; and
when a first configuration indicator is not set, receiving a second RV of the first TB from the first terminal through a resource among the one or more second transmission resources; and when the first configuration indicator is set, receiving the second RV of the first TB or a first RV of a second TB other than the first TB from the first 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.
