TECHNIQUES FOR DOWNLINK COORDINATED MULTI-POINT (CoMP) COMMUNICATIONS USING UNLICENSED RADIO FREQUENCY SPECTRUM BAND

摘要

Techniques are described for downlink coordinated multi-point (CoMP) procedures for access to a contention-based radio frequency spectrum band. A base station performs a contention procedure, such as a clear channel assessment (CCA) procedure, for access to the radio frequency spectrum band. The base station determines whether contention has been won for a time period, and communicates whether or not contention has been won to other base stations in a CoMP cooperating set. Based on the information exchanged between base stations in the CoMP cooperating set, coordinated communications is initiated to a UE with two or more of the base stations in the CoMP cooperating set.

1. A method for wireless communications by a base station of a coordinated multi-point (CoMP) cooperating set of base stations in a wireless communications network, comprising:
performing a clear channel assessment (CCA) procedure to contend for access to an unlicensed radio frequency spectrum band; determining a CCA status that indicates whether contention has been won for a time period; and communicating the CCA status to one or more other base stations in the CoMP cooperating set.
