Abstract
Provided is a first terminal for performing unicast communication between terminals in a wireless communication system. The first terminal may be configured to: transmit a packet to a second terminal through a first sidelink carrier; determine a failure of the first sidelink carrier based on at least one of a number of times of retransmission of the transmitted packet, a number of times of reception of hybrid automatic repeat request (HARQ) negative acknowledgement (NACK) or discontinuous transmission (DTX) for the transmitted packet, or a number of times of continuous out of synch (OOS) for the first sidelink carrier; and determine whether to perform a radio link failure (RLF) handling procedure or whether to perform a carrier failure handling procedure, based on a result of the determining of the failure and the first sidelink carrier, wherein the carrier failure handling procedure may be performed based on at least one of a connection state between the first terminal and a base station or a need for multi-carrier transmission.
