Abstract
A Central Unit (CU) is connected to multiple Remote Radio Heads (RRHs) over a backhaul. The spatial separation of units creates long round-trip times, which are addressed in the present disclosure. The enhanced operation allows for counting down a BackOff (BO) on either the RRH side or on the CU side. RRHs that perform the BO procedure can resolve the issue of insufficient InterFrame Space (IFS) time for the RRH to obtain Data from the CU and to invoke a BO. In addition, RRHs that perform the BO procedures are able to reduce channel access contention when multiple RRHs are performing BOs, while utilization efficiency for the medium can also be increased by the improved synchronization of BO and Clear Channel Assessment (CCA) status between the CU and RRHs.
