20080232342 | METHOD AND SYSTEM FOR ADAPTIVELY OBTAINING BANDWIDTH ALLOCATION REQUESTS - A method and apparatus for adaptively obtaining bandwidth requests in a broadband wireless communication system. The method and apparatus includes dynamically varying technique combinations enabling a plurality of users to efficiently request bandwidth from a shared base station. A user may “piggyback” a new bandwidth request upon, or set a “poll-me bit” within, presently allocated bandwidth. A base station may poll users, individually or in groups, by allocating unrequested bandwidth for new requests. Polling may respond to a “poll-me bit,” and/or it may be adaptively periodic at a rate based on communication status parameters, such as recent communication activity and connection QoS levels Group polling permits a possibility of collisions. Polling policies may be established for dynamically varying user groups, or may be determined for each user. Dynamic selection of appropriate polling techniques makes use of efficiency benefits associated with each technique. | 09-25-2008 |

20090185532 | ADAPTIVE CALL ADMISSION CONTROL FOR USE IN A WIRELESS COMMUNICATION SYSTEM - The invention relates to communication systems and to systems and methods for implementing adaptive call admission control (CAC) in such systems. Adaptive call admission control can determine what CPE to base station calls (connections) are allowed at any given time. CAC, coupled with precedence, can further determine what connections are suspended if less bandwidth is available than is currently committed. Multiple techniques are disclosed to select connections for suspension. These techniques include suspending enough connections through the affected CPE until there is enough bandwidth to meet the remaining commitment, randomly (or in a round robin fashion) choosing connection to suspend from the entire set of connection, and using precedence priority levels. | 07-23-2009 |

20090225776 | METHOD AND APPARATUS FOR A SELF-CORRECTING BANDWIDTH REQUEST/GRANT PROTOCOL IN A WIRELESS COMMUNICATION SYSTEM - 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 are re. 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. | 09-10-2009 |
