COUPLING UPLINK AND DOWNLINK CCA IN LTE-U

摘要

Methods, systems, and devices are described contention-based channel access procedures that may enhance efficiency in communications using unlicensed spectrum. A time period may be identified during which base stations perform contention-based downlink channel access procedures for access to a channel in an unlicensed spectrum. The base stations may be coordinated such that different base stations may seek channel access during different time intervals during the time period. Contention-based uplink channel access procedures for UEs may then be modified to favor one or more UEs that are associated with a base station that has won channel access.

主权项

1. A method for wireless communication, comprising:
identifying a time period during which at least a first base station and a second base station perform contention-based downlink channel access procedures for access to a channel in an unlicensed spectrum; determining that the first base station has won or is more likely to win the downlink channel access; and modifying a contention-based uplink channel access procedure for a first user equipment (UE) associated with the first base station to favor the first UE gaining access to the channel in the unlicensed spectrum.
