摘要： A system and method for mapping a combined frequency division duplexing (FDD) Time Division Multiplexing (TDM)/Time Division Multiple Access (TDMA) downlink subframe for use with half-duplex and full-duplex terminals in a communication system. Embodiments of the downlink subframe vary Forward Error Correction (FEC) types for a given modulation scheme as well as support the implementation of a smart antennae at a base station in the communication system. Embodiments of the system are also used in a TDD communication system to support the implementation of smart antennae. A scheduling algorithm allows TDM and TDMA portions of a downlink to efficiently co-exist in the same downlink subframe and simultaneously support full and half-duplex terminals. The algorithm further allows the TDM of multiple terminals in a TDMA burst to minimize the number of map entries in a downlink map. The algorithm limits the number of downlink map entries to not exceed 2n+1, where n is the number of DL PHY modes (modulation/FEC combinations) employed by the communication system.

摘要： Base stations having potentially interfering terminal stations that are geographically located on the same or similar diagonal or Line of Sight (relative to the base station) operate on a first set of time frames (e.g., “even” time frames). Similarly, base stations having potentially interfering terminal stations that are not geographically located on the same or similar diagonals operate on a second set of time frames (e.g., “odd” time frames). By alternating in their use of the even and odd frames, the potential for co-channel interference between terminal stations is minimized. Systems and methods are disclosed which reduce co-channel and adjacent channel interference between terminal stations of different cells as well as adjacent channel interference between terminal stations of adjacent cells. The methods and systems so described can be used during the deployment or expansion of a communication system in a region.

摘要： A method and system for prioritizing connection data that is associated with different classes of service for transmission in a frame based communication system. These classes of service can include CBR, nrt-VBR, MGR, and UPR traffic. One embodiment of the scheduling method and system uses hierarchical round-robin (HRR) with deficit round-robin (DRR). In this embodiment, the scheduling method and system guarantees minimum rates of nrt-VBR and MGR traffic to the connections. The excess bandwidth is then fairly allocated between the existing connections and their classes of service. For example, the excess is allocated for UBR traffic and for the excess demands of the nrt-VBR and MGR connections. In one embodiment, the scheduling method and system allocates the excess bandwidth in a frame to the existing connections using weighted round robin to differentiate between different classes of service. In one embodiment, excess allocation to nrt-VBR and MGR connections is rolled back into the deficit counters for the minimum guaranteed rates of nrt-VBR and MGR connections.

摘要： A bandwidth efficient subscriber unit initialization and synchronization method and apparatus is described. The inventive subscriber unit initialization and synchronization method and apparatus uses a combination of an access burst format and a data transportation technique to efficiently use bandwidth when initializing and synchronizing subscriber units in a time-synchronized communication system. Advantageously, the present invention provides a mechanism for a base station to receive multiple access bursts from multiple subscriber units in a single contiguous time period. In the preferred embodiment of the present invention, bandwidth is efficiently utilized by searching for multiple initial access bursts from multiple mobile stations during a single time period known as a new access opportunity. The preferred embodiment of the present invention initializes and synchronizes subscriber units in a “contention-based” manner.

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.
摘要翻译：公开了一种用于在宽带无线通信系统中分配带宽的方法和装置。一个实施例使用自校正带宽请求/授权协议。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。 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）允许带宽分配方法和装置“自校正”。另一个实施例利用了一个节省带宽的请求/授权协议来分配带宽。精简带宽请求/授权协议系统利用填充分组来请求减少对CPE的带宽分配。当BS调制解调器从CPE接收填充分组时，基站调制解调器提醒基站CPU。在提醒BS CPU之后，该方法可以减少相关CPE的带宽分配。

摘要： Systems and methods for providing a weight-based scheduling system that incorporates end-user application awareness are provided and can be used with scheduling groups that contain data streams from heterogeneous applications. Individual data queues within a scheduling group can be created based on application class, specific application, individual data streams or some combination thereof. Application information and Application Factors (AF) are used to modify scheduler weights to differentiate between data streams assigned to a scheduling group. One embodiment adjusts the relative importance of different user applications using dynamic AF settings to maximize user Quality of Experience (QoE) in response to recurring network patterns, one-time events, or both. One embodiment maximizes user QoE for video applications by dynamically managing scheduling weights is provided that incorporates the notions of “duration neglect” and “recency effect” in an end-user's perception of video quality in order to optimally manage video traffic during periods of congestion.

摘要： An advanced technology frame structure is described herein. The advanced technology frame structure can enhance a first technology frame structure in dimensions of time, frequency, or a combination of time and frequency. A second technology frame structure time division multiplexes second technology subframes with the first technology downlink and uplink subframes. The first technology downlink subframe can be divided into a first technology downlink subframe and one or more second technology downlink subframes. Similarly, the first technology uplink subframe can be divided into a first uplink subframe and one or more second technology uplink subframes. These principles can be expanded upon and can be applied in many communication systems.
