Patent ID: 7499728

Claim:
A method for transmitting and receiving weight information for creating transmission and reception beams in a wireless communication system using an adaptive antenna array scheme, the method comprising the steps of: (1) providing a first weight to a first error value obtained through a calculation for achieving a minimum cost function by a first scheme; (2) providing a second weight calculated from the first weight to a second error value obtained through a calculation for achieving a minimum cost function by a second scheme; (3) calculating a minimum error value from the weighted first error value and the weighted second error value for minimizing an error of a received signal; (4) calculating a reception weight for creating a reception beam using the received signal and the minimum error value; (5) calculating a transmission weight for creating of a transmission beam using the reception weight and a minimum error value of a received signal; (6) generation feedback information including the transmission weight; and (7) transmitting the feedback information.
