    摘要： A wireless network includes a relay station (RS) for extending wireless coverage of a base station. Data is sent by the base station and relayed through the RS to a mobile station (MS), where the data is associated with a preamble that is sent directly from the base station to the MS. A transmit power of the RS is adjusted for transmitting the data from the RS to the MS to reduce a difference between a first power level of the preamble received at the MS and a second power level of the data received at the MS. The uplink transmit power of the MS for the data sent to the RS is adjusted to compensate for the difference in path loss from MS to base station and MS to RS and to compensate for the difference in noise_plus_interference level at RS compared to that of the base station.

    摘要： A relay station is provided for use in a wireless communication system. The wireless communication system includes a plurality of base stations communicatively coupled to a backhaul network and at least one mobile station. The relay station is shared by at least a first base station and a second base station. The relay station includes a transceiver, a controller and relay circuitry. The transceiver transmits signals to and receives signals both base stations and a mobile station. Signals transmitted to the base stations include a single preamble, MAP and FCH. The controller is electrically connected to the transceiver and is operable to measure a signal quality of the mobile station while connected to the first base station. The relay circuitry is electrically connected to the controller and is operable to conduct a phased handoff from the first base station to the second base station based on the signal quality.

    摘要： A method dynamically changes a relay zone offset in a wireless communication system. The wireless communication system includes a base station, at least one relay station, and at least one mobile station. Each relay station is located a hop distance from the base station. A notification of a change in relay zone offset is transmitted to a relay station. Implementation of the change in relay zone offset is delayed for a predetermined amount of frames. Relay zone information is transmitted using the changed relay zone offset.

    摘要： A method selects a path for forwarding a data packet in a wireless communication system. A system capacity versus delay impact curve is calculated for a direct path to mobile station. The direct path has a capacity cost based on communication quality of a direct link between a base station and the mobile station. This curve is shifted by a predetermined time corresponding to an additional delay over a relay path to produce a projected capacity curve for the relay path having a second capacity cost determined according to a combined measure of signal quality of multiple links in the relay path. The second capacity cost is multiplied by a capacity cost ratio to produce a relay capacity curve. The direct path or the relay path is selected based on a comparison of the system capacity versus delay impact curve and the relay capacity curve according to a QoS requirement.
