Abstract
A self-correcting bandwidth request/grant protocol in a broadband wireless communication system. The protocol uses a combination of incremental and aggregate bandwidth requests. Stations primarily transmit incremental bandwidth requests to their associated base stations, followed by periodic transmissions of aggregate bandwidth requests. Risks are reduced that a base station erroneously issues duplicate bandwidth allocations to the same station for the same connection. Race conditions that may have occurred using only aggregate bandwidth requests are eliminated. Use of periodic aggregate bandwidth requests that express the current state of respective connection queues provides a “self-correcting” property.
