摘要： Practical methods and apparatuses are provided for determining network clusters in wireless backhaul networks comprising a plurality of hubs (102) and Remote Backhaul Modules (RBM) (104) based on link quality value (LQV) metrics. From an input LQV table of LQV values for each hub-RBM link (110), the link quality values are first ranked. Clusters are then identified from all the possible links based on the order of the highest link quality value to the lowest link quality value, any constraints on the number of RBMs per cluster, and clustering each RBM only once. Links with strong link quality values are chosen to optimize the LQV metric. LQV based clustering achieves a higher average LQV, e.g., average spectrum efficiency or weighted sum spectrum efficiency, for the entire backhaul network compared to the geographic location based clustering. The method is straightforward to implement and has low computational complexity.

摘要： A system is disclosed for performing a mobile station handover while continuing a multicast and broadcast service (MCBCS). The system includes a transceiver module transmitting from the mobile station multicast and broadcast service (MBS) zone criteria, including a list of one or more potential target base stations, to a serving base station, if a target base station is not in the same MBS zone as the serving base station. A handover request is made to one or more of the potential target base stations from the serving base station, determined based on the MBS zone criteria, where the MBS zone criteria includes an MCBCS continuity policy of the mobile station. A target base station is then selected, from the list of one or more potential target base stations, that satisfies the MBS zone criteria, and a handover process is performed to the target base station.

The system includes carrier frequency information to indicate that data in an MBS zone resides on a separate carrier, and to direct the subscriber stations to receive MBS data on the separate carrier. The method comprises establishing an MBS MAC connection between a subscriber station and a base station in a MBS zone, processing carrier frequency information to determine whether data associated with the MBS zone resides on a separate carrier, and if so, transmitting the MBS data on the separate carrier.

摘要： Methods and apparatus are provided for managing interference in a wireless backhaul network comprising a plurality of hubs, each hub serving a plurality of remote backhaul modules (RBM), using power control with a one-power-zone (OPZ) constraint. Each hub uses a transmit frame structure comprising a plurality of zones, each RBM is scheduled on a different zone, and the same power level is maintained across all zones within a transmit frame. Under the OPZ constraint, and for scheduling policies under which the number of zones assigned to each RBM is fixed, the power and scheduling sub-problems are decoupled. This enables power control independent of scheduling, using methods having lower computational complexity. Methods are disclosed comprising iterative function evaluation or Newton's method approaches based on a weighted sum-rate maximization across the network, which can be implemented in a distributed fashion. Some of the methods can be implemented asynchronously at each hub.
