摘要： When an event associated with a mobile station occurs, a relay station requests a base station to allocate a dedicated control channel required for transmitting control information on the mobile station to the base station. Next, when the control information on the mobile station is generated, the relay station transmits the control information to the base station through the dedicated control channel. Accordingly, since the base station allocates the dedicated control channel to the relay station in advance before the control information is generated in the relay station, the relay station can transmit the control information to the base station with a minimum of time delay.

摘要： The present invention relates to a system for selecting a switched beam for supplying a maximum received power to a subscriber station, and a method thereof. The number of switched beams used by a base station is limited, and a weight value vector for forming the switched beam is predefined. The subscriber station uses a pilot signal for discerning transmitting antennas to estimate channel values for the respective transmitting antennas, and uses the channel values and the predefined weight value vectors to determine a switched beam for supplying a maximum signal-to-noise ratio (SNR). The subscriber station notifies the base station of an identifier of a selected beam by using a feedback channel, and the base station uses the switched beam to transmit traffic data.

摘要： A transmitting apparatus and receiving apparatus of a multi-carrier system using multiple antennas is proposed. A linear complex field (LCF) encoder performs linear precoding of input signals to be transmitted using a linear complex matrix based on the number of antennas and the number of subcarriers, and a subcarrier allocator allocates a subcarrier to each precoded signal. A transmitter transmits the signals through the multiple antennas. In a receiving apparatus, a subcarrier de-allocator extracts a linear-precoded signal by de-allocating a subcarrier of the received signal, and an LCF decoder outputs a bit reliability of the received signal based on the number m of antennas and the number n of subcarriers. Performance may be improved by using space diversity using multiple antennas and frequency diversity using OFDMA, and system complexity may be reduced by using a lattice reduction and a 2-branch Chase decoder.
