METHOD AND SYSTEM FOR RESPONDER-AWARE RELAY STATION SELECTION IN WIRELESS COMMUNICATION NETWORKS

摘要

PURPOSE: A method and a system for selecting a transponder-recognition station are provided to select a wireless relay station from candidate wireless relay stations based on an evaluation result for a driving parameter of the candidate wireless relay stations. CONSTITUTION: A source station transmits a wireless relay selection request frame to a destination station(203). The source station executes a required beam-forming training process or a channel estimation process with each wireless relay station(205). The destination station executes the required beam-forming training process or a channel estimation process with each wireless relay station(206). The destination station transmits a plurality of relay channel measurement report to the source station(207). The source station selects the suitable relay station from the candidate relay stations(209).
