<p>A method for performing beam tracking in a wireless communication network is provided. In the method, a transmitter station emits beam patterns including respective beam pattern indices to receiver stations and receives a feedback index indicating one of the beam patterns from each receiver station during a predetermined channel time after the emission of beam patterns is completed. A beam pattern feedback is processed using a simple code, thereby minimizing the amount of information and hardware required for beam search and tracking. In addition, in uni-directional beam tracking, it is possible to perform tracking on a number of beam links at once and a sub-channel that can be used for beam tracking and search is allocated to each station to allow a number of stations to simultaneously perform beam search, thereby reducing the amount of used channel time.</p> |
