PROCÉDÉ ET APPAREIL POUR L'EXÉCUTION D'UNE TRANSMISSION DE LIAISON LATÉRALE BASÉE SUR UNE DEMANDE DE PROGRAMMATION BASÉE SUR LA CONCURRENCE DANS UN SYSTÈME DE COMMUNICATIONS SANS FIL

摘要

A method and apparatus for performing a sidelink (SL) transmission in a wireless communication system is provided. A user equipment (UE) transmits a contention based scheduling request (CB-SR) to an eNodeB (eNB) by using CB-SR resources to request SL transmission resources, and determines whether a SL grant for the SL transmission resources is received or not. If the UE does not receive the SL grant until a timer expires, the UE may transmit non-contention based SR to the eNB or autonomously select SL resources from resource pool to perform SL transmission.
