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： A method and system for wireless communication with a mobile device. A first wireless communication network, such as a WiMax or cellular-based network, has a first maximum wireless speed. A second wireless communication network, such as a near-photonic speed gigabit link (“GiLink”) network, has a second maximum wireless speed. The second wireless maximum speed is less than the first maximum wireless speed. The second wireless communication network provides control plane services for wireless communication between the mobile device and the first wireless communication network.

摘要： For each base station, transmit power level variables (I values) for each resource block allocated by the base station are initialized. The I values are used in a model to find sub-gradients for each base station. Neighboring base stations exchange the sub-gradients. For each base station, the base station's sub-gradient and the base station's neighbors' sub-gradients are used in the model to update the I values. Neighboring base stations then exchange the updated I values. For each base station, the base station's updated I value and the base station's neighbors' updated I values are used in the model to update the initial sub-gradients. The updated sub-gradients are then exchanged and used for another update of the I values. After a number of iterations, the I values are used to establish a transmit power level per resource block.

摘要： Some embodiments of the invention provide an implementation for a multi-hop wireless backhaul network. These embodiments can advantageously be deployed in dense urban areas and/or co-located with wireless access nodes, such as base-stations of a cellular wireless communication system. Preferably wireless links between constituent network nodes are set-up hierarchically. A basic result of this is that peer-to-peer (child-to-child) communication is generally prohibited and circuits are forced to conform to a topology. The multi-hop wireless backhaul network may be used to carry delay sensitive, high-density last mile circuit traffic over Non-Line-Of-Sight (NLOS) broadband radio links. Moreover, some embodiments of the invention provide a method of path-healing for re-routing of circuit traffic from circuits that have experienced catastrophic failures.
