    摘要： A mobile communication apparatus including a base station and at least two mobile stations, having multiple antennas, respectively is provided. In the mobile communication apparatus, the base station restores from feedback signals transmitted from the mobile stations weight information determined in the mobile stations, generates from the restored weight information downlink control information ensuring maximum throughput to each of the mobile stations, and selects from among data of all of the mobile stations data of a desired mobile station(s) to be transmitted, based on the downlink control information. Each of each of the mobile stations has at least one mobile station antenna, the base station has at least two base station antennas, and the downlink control information includes mobile station selection information, an optimal basis matrix index, and optimal gain indices. As a result, nominal peak throughput in multi-antenna mobile communications can be efficiently achieved at low costs.

    摘要： Disclosed is a wireless communication apparatus and method for a multiple transmit and receive antenna system using multiple codes. In suggested detection algorithm, a successive interference cancellation (SIC) scheme is employed in both an antenna domain and a code domain by successively canceling multi-code interference (MCI). An effective transmit power allocation method suitable for the detection algorithm is suggested. Transmit power allocated to each code is calculated. The transmit power is determined as a simple ratio of power of a certain signal to power of a next code signal. Based on the calculated code transmit power, transmit power for each transmit antenna is allocated. Thus, information about transmit power calculated at a receive end is feedback to a transmit end through a feedback channel.

    摘要： The effective performance metric and achieving method of a multi-user multiple-input multiple-output (MU-MIMO) communication system are provided. A number of feedback bits of channel information may be determined based on an effective spectral efficiency (ESE). The ESE may correspond to a metric of the throughput performance with respect to a total radio resource including an uplink radio resource and a downlink radio resource. User-scheduling may be based on the feedback information that is based on the ESE, and thus, the throughput performance of the communication system may be enhanced.
