BEANFORMING METHOD USING MULTIPLE ANTENNA

摘要

A low power beam forming strategy using a multiple antenna is provided to prevent power consumption of a base station in case signal is transmitted to the uplink by utilizing the multiple antenna. One or more training signal is received from a plurality of base station antennas by using a plurality of mobile station antenna(S310). The downlink channel by cell site antennas and mobile station antennas uses the training signal(S320). The beam vector is generated by using the downlink channel(S350). The beam is formed by applying the beam vector on mobile station antennas(S370).
