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.

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.

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

摘要： One or more relay stations may be employed along a wireless communication access path between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add scheduling information to the PDUs before they are delivered to the downstream intermediate relay stations or egress stations. The scheduling information is used by the downstream stations to schedule the PDUs for further delivery. The scheduling information may also be used by the egress station to schedule the PDUs for delivery. The scheduling information added to the PDU by the ingress station bears on a QoS class associated with the PDU, a deadline for the egress station to deliver the PDU, or a combination thereof.

摘要： Security in wireless communication networks that employ relay stations to facilitate communications between base stations and mobile stations is enhanced. In one embodiment, resource information provided to one or more relay stations from a base station or another relay station is encrypted prior to being delivered to the one or more relay stations. Only authorized relay stations are allocated an appropriate key necessary to decrypt the resource information. As such, only appropriate relay stations are able to access and use the resource information to effect communications directly or indirectly between the base stations and the mobile stations. In certain embodiments, the resource information is delivered between the various base and relay stations using either unicast or multicast delivery techniques.
