Embodiment Construction

[0024] In the following, referring to some embodiments of the present invention in detail, examples of the present invention will be described with accompanying drawings.

[0025] figure 1 In accordance with an embodiment of the present invention, a schematic diagram of an example LAA wireless communication system 100 using an LBT channel access mechanism with QoS configuration. The wireless communication system 100 includes one or more wireless communication networks, and each wireless communication network has infrastructure units, such as 102 and 104. The infrastructure unit may also be called an access point, an access terminal, a base station, an eNB, or other terms in the field. Each of the base stations 102 and 104 serves a geographic area. The geographic areas served by wireless communication stations 102 and 104 overlap in this example.

[0026] The base station 102 is an authorized base station, and it communicates with the UE 101 through an authorized frequency band. ...

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 CAPto 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).
