摘要： An exemplary method of communicating includes a relay node that uses a cell identifier that is also used by a base station having a coverage area within which the relay node is located. The method includes determining that a mobile station is within a communication range of the relay node. A transmission power from the relay node is controlled so that the total transmission power of at least one transmission from the relay node and the base station corresponds to a selected transmit power limit. A timing of a downlink transmission from the base station and the relay node is coordinated based on a schedule determined by the base station. At least one uplink control parameter is set at the base station based upon uplink information regarding a link between the mobile station and the relay node.

摘要： A multicast status availability indication from an anchor (24) is provided to a plurality of base nodes (22) that are part of a multicast group serviced by the anchor (24). The availability status indication in one example is sent autonomously by the anchor (24) independent of any inquiry or attempted setup of a new session with that anchor by a base mode (22). The base modes (22) maintain a candidate anchor set that includes information regarding currently available anchors for establishing new sessions, for example.

The method comprises establishing a bandwidth over which the radio resources transmit signals, the bandwidth being comprised of an edge-band and a center-band. Narrow band radio resources are assigned to a portion of the bandwidth that is at least partially within the edge-band.

摘要： A communication system includes a decentralized, flat architecture where a plurality of base nodes each include controller capabilities so that a centralized base node such as a radio network controller is not required. At least one of the base nodes acts as an anchor node. The anchor node associates a time stamp with at least one packet and provides that to the plurality of base nodes. In one example, a multicast approach is used by a router device for distributing the packet and the associated time stamp to the plurality of base nodes. Each base node controls a timing of a transmission of the at least one packet over a wireless interface responsive to the associated time stamp.
