METHOD, BASE STATION AND CORRESPONDING MOBILE STATION FOR OBTAINING DOWNLINK CHANNEL DIRECTIONAL INFORMATION |
摘要 |
Disclosed in the present invention is a method in the Multiple Input Multiple Output system for obtaining downlink channel directional information. The method includes steps: a base station receives downlink channel directional information which is fed back by a mobile station during the feedback period, and determines the relation between an uplink channel directional information and the received downlink channel directional information; the base station also estimates the downlink channel directional information of non-feedback sub-frame by use of the relation, those non-feedback sub-frame are not fed back during the feedback period. Furthermore, a base station and corresponding mobile station in MIMO system are also provided in the present disclosure.
