摘要： A method and system for wireless communication in which a plurality of media access control (“MAC”) packet data units (“PDUs”) corresponding to a plurality of wireless communication connections are received. The plurality of MAC PDUs is grouped into a relay packet and the relay packet is transmitted. Such grouping and transmission of the relay packet is performed by one or more relay nodes. The traffic control for the transmission can also be based on centralized or decentralized routing control and/or centralized or decentralized QoS control.

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.

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.

摘要： In a method of operating a relay station in a multihop wireless relay network, the relay station in communication with a superordinate station and a subordinate station: a downlink transmission from the superordinate station is received at a first carrier frequency; an uplink transmission from the subordinate station is received at a second carrier frequency; a downlink transmission to the subordinate station is transmitted at the first carrier frequency; and an uplink transmission to the superordinate station is transmitted at the second carrier frequency. The communication between the relay station and the superordinate station may be scheduled using frames, where each frame comprises: a downlink portion at the first carrier frequency, the downlink portion comprising a first downlink subframe for communication between the superordinate station and a first plurality of stations, and a second downlink subframe for communication between the superordinate station and a second plurality of stations; and an uplink portion at the second carrier frequency, the uplink portion comprising a first uplink subframe for communication between the superordinate station and the first plurality of stations, and a second uplink subframe for communication between the superordinate station and the second plurality of stations. The first downlink subframe may correspond with a first time interval, and the first uplink subframe may correspond with a second time interval, where the first time interval and the second time interval do not overlap. The relay station may be one of the first plurality of stations, whereby the receiving the downlink transmission occurs in the first downlink subframe, and the transmitting the uplink transmission occurs in the first uplink subframe.
