Abstract
This invention provides a type of method used for providing channel aware relays in enhanced relay clusters. This method is based on the Centralized Cluster Relay Implementation Proposal, and is implemented by transferring MMR-BS channel information based functions to RS. Specifically, in this invention, RS receives authorization from the MMR-BS to receive the channel information from the MS or next single-hop RS point within its single-hop range, and, after performing applicable channel aware relays, reports the processing result to MMR-BS; MMR-BS configures the signal according to the processing result and joins RS to transmit the control signal to the cluster MS. Using the method provided by this invention can reduce the channel overhead between MMR-BS and RS, and at the same time ensure that the RS composition is simple, and the production costs are low.
