Abstract: A method and apparatus for performing sidelink transmission in an exceptional case in a wireless communication system is provided. A user equipment (UE) receives information on normal resource pools and exceptional resource pools on multiple carriers. The UE selects at least one normal resource pool among the normal resource pools on the multiple carriers, and performs the sidelink transmission by using the at least one normal resource pool. Upon detecting occurrence of the exceptional case, i.e. radio link failure (RLF), a handover, transition from an idle state to a connected state or change of dedicated sidelink resource pools within a cell, the UE selects at least one exceptional resource pool, which is mapped to the at least one normal resource pool, among the exceptional resource pools on the multiple carriers, and performs the sidelink transmission by using the at least one exceptional resource pool.

Abstract: User equipment (UE) can transmit UE support data for semi-persistent scheduling (SPS) to an evolved NodeB (eNB) in order to effectively allocate SPS resources for vehicle-to-everything (V2X) communication. The release of SPS can be directed by means of the UE support data. More specifically, a terminal receives, from an eNB, a plurality of SPS configurations for a plurality of logical channels, and transmits, to the eNB, UE support data comprising an SPS release directive for any one logical channel from among the plurality of logical channels.
