Abstract
A method and apparatus for allocation of channel resources for relay stations operating in a multihop wireless communication system is provided for herein. The method and apparatus includes a signaling protocol between a base station scheduler and a relay station scheduler so as to achieve efficient utilization of the sector channel resources, while minimizing signaling overhead due to base station-relay station scheduler interaction.
Claims15
A method for allocating bandwidth within a multihop wireless communication network comprising:
- at a relay station:
- receiving and storing subscriber station bandwidth allocation requests from one or more subscriber stations associated with the relay station;
- computing an aggregated bandwidth using a sum of the received subscriber station bandwidth allocation requests;
- and
- requesting the aggregated bandwidth from an associated base station.
A method for allocating bandwidth to a relay station within a multihop wireless communication network comprising:
- requesting bandwidth allocation by at least one subscriber station from the relay station;
- computing an accumulated bandwidth allocation for a relay station-managed zone by the relay station for at least one next communication frame;
- sending a request for the computed accumulated bandwidth allocation for the at least one next communication frame from the relay station to an associated base station;
- and
- granting a bandwidth allocation for the at least one next communication frame by the base station.
A method of operation of a base station for allocating bandwidth to a relay station within a multihop wireless communication network comprising:
- receiving one or more bandwidth allocation requests from one or more other network entities;
- and
- sending a relay station bandwidth reallocation to the relay station based on the received requests.
A method of operation of a base station for allocating bandwidth to a relay station within a multihop wireless communication network comprising:
- determining a subscriber station input queue size for each of a plurality of subscriber stations managed by the relay station;
- computing a relay station zone size as an aggregation of each of the subscriber station input queue sizes;
- and
- providing the relay zone size to the relay station.
