摘要： Disclosed are a method and a system for transmitting/receiving signals in a mobile communication system using a multiple input multiple output adaptive antenna array scheme. A first receiver calculates a reception weight value by using a de-spread signal of a reception signal for creating a reception beam of the first receiver and calculates a transmission weight value by using the calculated reception weight value for creating a transmission beam of the second transmitter, thereby creating feedback information including the transmission weight value. A first transmitter transmits the feedback information to a second receiver. The second receiver receives the feedback information and the second transmitter detects the transmission weight value from the feedback information received in the second receiver, and creates the transmission beam corresponding to the detected transmission weight value in order to transmit a signal by applying the transmission beam to the signal.

摘要： A method for transmitting and receiving weight information for creating transmission/reception beams in a mobile communication system using a multiple input multiple output adaptive antenna array scheme. The method includes a receiver receiving a predetermined signal, and differentially providing weights to a first scheme and a second scheme for minimizing an error between the received signal and a predetermined reference signal, thereby obtaining a minimum error value. The receiver generates a despread signal by despreading the received signal, produces a reception weight for creation of a reception beam by the receiver through calculation using the despread signal and the minimum error value, and produces a transmission weight for creation of a transmission beam by a counterpart transmitter through calculation using the reception weight and the minimum error value. The receiver generates predetermined feedback information including the transmission weight and a transmitter transmits the feedback information to a counterpart receiver.

A base station apparatus for the radio communication system includes a channel estimator and a calculator. The channel estimator receives a UL sounding signal to estimate a first UL CSI and receives a UL sounding signal weighted with a DL CSI to estimate a second UL CSI. The calculator calculates calibration values for the respective antenna pairs using the first UL CSI and the second UL CSI. Information necessary for channel calibration is transmitted and received in an analog format. Accordingly, it is possible to minimize the waste of resource and time necessary for channel calibration.
