摘要： 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.

摘要： 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.

摘要： A method and apparatus for packing management messages in a broadband wireless communication system. Management messages are sent across a link in packets addressed to a particular connection, where the address identifies messages which may be specially treated. Such special treatment may include recognition of an overall message conveyed in such packets as containing one or more implicit messages embedded within the overall message. Two methods are disclosed to efficiently convey such management messages. First, each packet of information sent across the link may include a message type identifier, in which case it need not be repeated in the payload of the packet, and a number of such messages may be sent within a packet. Second, a packet of information may contain mixed management messages, in which case the byte with the message type identifier should be included with each such message. In this case, an overall message may be constructed from individual management messages simply concatenated together. Using either method, the management messages are packed into packets so that messages in a first packet may be parsed and acted upon without a need for any subsequent packets which may be necessary to convey an entire message. This is accomplished by taking any message which will not fit in a first packet may be made to be ignored, such as by being replaced with a padding pattern. In this way, any subsequent packet will have management messages which begin at the start of the effective data payload. Padding may also be added before or after an end of message or trailer information which defines the end of an overall message.

摘要： A method and apparatus for a self-correcting bandwidth request/grant protocol in a broadband wireless communication system is disclosed. The self-correcting bandwidth request/grant protocol utilizes a combination of incremental and aggregate bandwidth requests. In accordance with the present inventive protocol, CPEs primarily transmit incremental bandwidth requests to their associated base stations, followed by periodic transmissions of aggregate bandwidth requests. The use of incremental bandwidth requests reduces risks that a base station erroneously issues duplicate bandwidth allocations to the same CPE for the same connection. Race conditions that may have occurred using only aggregate bandwidth requests are eliminated by requiring the CPEs to request bandwidth in an incremental manner. However, use of periodic aggregate bandwidth requests (that express the current state of their respective connection queues) allows the present bandwidth allocation method and apparatus to be “self-correcting”. The present method is self-correcting because errors that may have been introduced due to lost incremental bandwidth requests are corrected by the base stations when the aggregate bandwidth requests are received and processed. Upon receipt of the aggregate bandwidth requests, the base stations reset their records to correctly reflect the current bandwidth requirements of their associated CPEs. Periodic use of aggregate bandwidth requests provides a self-correcting bandwidth allocation protocol yet without the bandwidth overhead (e.g., bandwidth required to transmit acknowledgements) typically associated with the prior art protocols (such as the guaranteed delivery protocols).
摘要翻译：公开了一种用于宽带无线通信系统中的自校正带宽请求/授权协议的方法和装置。自校正带宽请求/授权协议使用增量和聚合带宽请求的组合。根据本发明的协议，CPE主要向其相关联的基站发送增量带宽请求，随后是聚合带宽请求的周期性传输。使用增量带宽请求减少了基站错误地向相同连接的相同CPE发布重复带宽分配的风险。通过要求CPE以递增方式请求带宽，消除了可能仅使用聚合带宽请求发生的种族条件。然而，使用周期性聚合带宽请求（表示其相应连接队列的当前状态）允许当前带宽分配方法和装置“自校正”。本方法是自校正的，因为当接收和处理聚合带宽请求时，基站由于丢失的增量带宽请求而引入的错误被校正。收到总带宽请求后，基站重新设置其记录，以正确反映其相关CPE的当前带宽需求。聚合带宽请求的定期使用提供了自校正带宽分配协议，而没有通常与现有技术协议（例如保证传送协议）相关联的带宽开销（例如，传送确认所需的带宽）。

摘要： A system and method providing a wireless broadband connection between base stations and customer sites. The system includes indoor units, within the base stations and customer sites, that communicate across cables to outdoor units. The indoor units link to routers, switches and other devices and services. The outdoor units transmit and receive wireless data and send it to the indoor units. The indoor units control the functioning of the outdoor units by transmitting digital messages along the interface cables. The outdoor units report various detector values to the indoor units, which allows the indoor units to tune and adjust several functions within the outdoor units. Several embodiments for automatically calibrating the receive path gain in the base stations to compensate for the base station cable between the indoor unit and outdoor unit are described. In addition, an improved transmit power control technique which is not affected by modulation type, is also described.

摘要： A method and apparatus for allocating bandwidth in a broadband wireless communication system is disclosed. One embodiment uses a self-correcting bandwidth request/grant protocol. The self-correcting bandwidth request/grant protocol utilizes a combination of incremental and aggregate bandwidth requests. CPEs primarily transmit incremental bandwidth requests to their associated base stations, followed by periodic transmissions of aggregate bandwidth requests. The use of periodic aggregate bandwidth requests (that express the current state of their respective connection queues) allows the bandwidth allocation method and apparatus to be “self-correcting”. Another embodiment utilizes an abridged bandwidth request/grant protocol to allocate bandwidth. The abridged bandwidth request/grant protocol system utilizes padding packets to request a reduction in bandwidth allocation to a CPE. A base station modem alerts a base station CPU when the BS modem receives a padding packet from a CPE. After alerting the BS CPU the method can reduce the associated CPE's bandwidth allocation.
