Abstract
A method of beam administration in a cellular or wireless network is proposed. Cellular/wireless networks operating at Ka or higher frequency band require the use of directional antenna (or through array-based beamforming) to compensate for sever pathloss. Maintaining antenna pointing and tracking accuracy is essential in many phases of the communication process. By using uplink pilot signals for beam alignment/tracking, combined with switched beamforming at the UE and adaptive beamforming at the BS, an effective beam administration is achieved with reduced overhead, complexity, and cost.
