BEAM FORMING METHOD, COMMUNICATION STATION AND MOBILE STATION

摘要

Disclosed are a beam forming method, a communication station and a mobile station, which are applied to a radio communication system consisting of multiple coordinating cells. The beam forming method comprises: a communication station of each coordinating cell determining, according to pitch angle indication information and first channel information from a mobile station of the cell as well as pitch angle indication information and second channel information from communication stations of the other coordinating cells, a three-dimensional beam forming weight; and the communication station of each coordinating cell performing weighted processing on data to be transmitted according to the weight, and sending the data to the mobile station of the cell. The beam forming method solves the problems in the related art that two-dimensional beam forming cannot distinguish mobile stations with different vertical pitch angles for processing and the feedback quantity is large, so as to lower the feedback quantity and also reduce co-channel interference of different mobile stations, thereby improving the system performance.
