BEAMFORMING TRAINING METHODS, APPARATUSES AND SYSTEM FOR A WIRELESS COMMUNICATION SYSTEM

摘要

The present invention provides methods and apparatuses for beamforming training at a service and control point and a user station, and a system for beamforming training for a wireless communication system. According to the present invention, a method for beamforming training at a service and control point may comprise: transmitting training sequences to multiple user stations by using switched transmit antenna weight vectors; determining optimum transmit antenna weight vectors of the service and control point based on channel information that is fed back from each user station of the multiple user stations and related to channel condition of own link and cross links of the each user station. According to the present invention, there is provided a spatial-reuse based simultaneous beamforming training technology, which may satisfy the demands of a dense-user application; moreover, has a high spectrum efficiency and saves beamforming training time.
