摘要： Provided are an ARQ apparatus and method for a multihop system in a broadband wireless access communication system. The ARQ method of a relay includes determining if the relay successfully receives specific data from a source and transmitting the specific data to a destination; receiving feedback data from the destination and determining if the destination successfully receives the specific data; generating feedback data including data indicating if the relay and the destination successfully receive the specific data, and outputting the feedback data to the source; and retransmitting the specific data, when the relay successfully receives the specific data but the destination fails to receive the specific data. Accordingly, when the MH-BTS successfully receives the data from the source but the destination fails to receive the data, the source does not retransmit same data to the MH-BTS.

摘要： An apparatus and method for changing an uplink power control scheme according to mobile status in a TDD mobile communication system are provided. A subscriber station transmits to a base station a power control change request message including information about a requested power control scheme. Upon receipt of the power control change request message, the base station selects a power control scheme for the uplink of the subscriber station and transmits to the subscriber station a power control change command message including information about the selected power control scheme. The subscriber station extracts, upon receipt of the power control change command message from the base station, the power control scheme information from the power control change command message and selects a power control scheme according to the extracted information.

摘要： A closed-loop multi-antenna system and method thereof are provided. A transmitter includes a feedback information processor and a first transmit unit. A receiver includes a channel estimator, a feedback information generator and a second transmit unit. The feedback information processor receives feedback information from the receiver, calculates each of a sum rate in a multi-user mode and a sum rate in a single-user mode using the feedback information, and selects one of the single-user mode and the multi-user mode as a transmission mode depending on a comparison result between the sum rate in the multi-user mode and the sum rate in the single-user mode. The channel estimator acquires channel quality information (CQI) for each data stream transmitted individually via each antenna group. The feedback information generator determines the CQI associated information from the CQI acquired individually for each antenna group corresponding to the transmission mode.

摘要： An apparatus and method for assigning subchannels of a transmitter in a communication system. The method includes dividing an entire frequency band into m subcarrier groups; mapping each of the m subcarrier groups to a subcarrier group index, wherein a subchannel includes n subcarriers selected from each of the m subcarrier groups corresponding to a subcarrier group index sequence; determining that a first data is needed to transmit in a first timing point; and assigning a first subchannel in the first timing point using a first subcarrier group index sequence. The first subcarrier group index sequence is different from a second subcarrier group index sequence used for assigning a second subchannel in a second timing point.
