Abstract

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.

Description

technical field [0001] The present invention relates to a method and apparatus for allocating beam search time required for highly directional radio transmissions to perform efficient beam search and tracking. Background technique [0002] In a multiple-input multiple-output (MIMO) communication system, a transmitter station uses multiple transmit antennas and a receiver station uses multiple receive antennas for data communications. A single MIMO channel created by an antenna can be broken down into independent channels. Each independent channel is a sub-channel (or transport channel) in the spatial domain of the MIMO channel and occupies a range. MIMO systems may exhibit improved performance (eg, improved transmit capability) when using the additional range created by the multiple antennas. [0003] MIMO systems are classified into two types, open loop and closed loop. In an open-loop system, space-time coding techniques are typically implemented in the MIMO transmitter...
