    摘要: A method of transmitting feedback information in a wireless communication system is disclosed. More specifically, the method comprises a mobile station (MS) which determines whether to transmit feedback information to a base station (BS) without solicitation from the BS. After determining to do so, the MS transmits a request message to request the BS to allocate an uplink resource for transmitting at least one unsolicited header and thereafter receives the uplink resource allocation from the BS. Lastly, the MS transmits the at least one unsolicited header via the allocated uplink resource.

    摘要: A method for controlling handover using a Relay Station (RS) whose coverage includes at least one mobile station is provided. In the method, the RS monitors an uplink band allocated to a mobile station and obtains a Connection ID (CID) and a Medium Access Control (MAC) address the mobile station. The RS transmits a scanning request message including the MAC address of the mobile station to a base station. The RS then receives a scanning response message including scanning timing and scanning interval information from the base station and scans neighbor base stations using the information included in the scanning response message. This method more efficiently performs handover of mobile stations in the RS coverage.

    摘要: A packet retransmission method for use in a communication system transmitting a signal via at least two antennas is disclosed. The packet retransmission method includes the steps of: a) receiving a signal corresponding to a specific packet, and independently transmitting a signal via the at least two antennas corresponding to the received signal; b) receiving a NACK signal associated with the packet; and c) independently applying an STTD to a real part and an imaginary part of each signal transmitted at step (a), and transmitting the STTD-resultant signal. Therefore, the method separates a real part and an imaginary part from each other, obtains a STTD gain, and can efficiently transmit a packet.
