摘要： Methods and apparatus for management of network slices in a communication network such as a 5th generation wireless communication network are provided. Management planes may be provided which are separate from the plurality of network slices. A connection manager residing in a management plane receives an indication that a mobile device is to be associated with the communication network. The connection manager may reside at an access node or in the core network. A network slice is determined, and the connection manager transmits instructions, to one or more network nodes, to associate the mobile device with the network slice. The instructions may be provided to a local connection manager. The slice may be requested explicitly by the mobile device, or determined based on device and/or network requirements.

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.

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.
