Patent abstract
A method of channel access procedure and QoS provisioning is proposed. When more than one user equipments (UEs) contend uplink transmission for a given time slot in an unlicensed band, uplink listen-before-talk (LBT) scheme should perform in a proper way to reflect service prioritization. The base station first determines the Channel Access Priority (CAP) for uplink LBT, and then signals such CAP to the UE via PDCCH. Upon receiving the CAP, the UE performs LBT procedure with corresponding CAP before uplink transmission. For example, the CAP can be determined based on QoS class identifier (QCI) of the radio bearer or based on the MAC layer logical channel prioritization (LCP).
