METHOD AND APPARATUS FOR PROCESSING DOWNLINK COMMUNICATION AND ASSISTANT METHOD AND APPARATUS THEREOF

摘要

The invention provides a method and apparatus for processing downlink communication and a corresponding assisting method and apparatus. According to an embodiment of the invention, there is provided a method for assisting a base station in processing downlink communication in a user equipment, which includes the steps of: estimating a downlink channel between the base station and the user equipment; determining a spatial correlation matrix between the base station and the user equipment according to the result of estimating the downlink channel; determining at least one pre-coding vector among a plurality of pre-stored pre-coding vectors based upon the spatial correlation matrix; and notifying the base station about the determined at least one pre-coding vector and spatial correlation matrix. The invention improves the performance of a system, improves the average throughput and the throughput of an edge user of the multi-user MIMO system and has a wider applicability scope then the original codebook and feedback mechanism.
