Abstract

The invention discloses a beam forming method, communication stations and mobile stations. The beam forming method, the communication stations and the mobile stations are applied to a wireless communication system comprising a plurality of collaborative cells. The beam forming method comprises the steps of enabling the communication station of every collaborative cell to determine weight of three-dimensional beam forming according to pitch angle instruction information and first channel information coming from the communication station of the cell and pitch angle instruction information and second channel information coming from the communication stations of other collaborative cells; and enabling the communication station of every collaborative cell to perform weighting processing on to-be-sent data according to the weight, and sending the data to the mobile station of the cell. By applying the beam forming method, the problems that two-dimensional beam forming cannot be used for distinguishing processing of the mobile stations with different pitch angles and feedback quantity is large in the prior art are solved, co-channel interference of different mobile stations is reduced while the feedback quantity is reduced, and system performance is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a beam forming method, a communication station and a mobile station. Background technique [0002] The traditional cellular network topology is a point-to-multipoint transmission mode from one communication station to multiple mobile stations. For communication stations at the edge of a cell, this transmission mode has relatively large co-channel interference between cells. A method to solve this inter-cell co-channel interference can be to combine multiple communication stations, and the communication stations cooperate with each other to turn the interference signal into a useful signal. This system that utilizes multiple communication stations to communicate with multiple mobile stations on the same time-frequency resource is called multipoint transmission. Coordinated Beamforming (CB for short) is one of the widely used and easy-to-implement multipoint transmission technol...
