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.

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 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 UBR 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.
摘要翻译：一种用于对连接数据进行优先级划分的方法和系统，所述连接数据与基于帧的通信系统中的不同服务等级相关联以进行传输。这些服务类别可以包括CBR，nrt-VBR，MGR和UBR流量。调度方法和系统的一个实施例使用具有赤字循环（DRR）的分层循环（HRR）。在本实施例中，调度方法和系统保证连接的nrt-VBR和MGR业务的最小速率。然后在现有连接及其服务等级之间公平分配超额带宽。例如，超额分配用于UBR流量以及nrt-VBR和MGR连接的超额需求。在一个实施例中，调度方法和系统使用加权轮询将帧中的多余带宽分配给现有连接，以区分不同类别的服务。在一个实施例中，对nrt-VBR和MGR连接的最小保证速率的冗余分配回滚到赤字计数器中。

摘要： An apparatus, system and method for converting data in a first packet format, having overhead data in the form of headers and/or trailer padding, into a second, variable-length packet format, in which some of the header and/or trailer overhead is removed during conversion in order to more efficiently utilize the limited bit rate capacity of a link which will convey the data in the second format. Embodiments include a communication subnetwork for interconnecting a plurality of users to a wide area network through a wireless link, an Asynchronous Transfer Mode (ATM) switch for converting ATM cells into a variable-length packet format, and a convergence system for converting ATM cells into data packets in Media Access Control (MAC) format.

摘要： A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The inventive method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. In accordance with this technique, currently active CPEs request bandwidth using previously unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE. By using a combination of bandwidth allocation techniques, the present invention advantageously makes use of the efficiency benefits associated with each technique.

摘要： An adaptive time division duplexing (ATDD) method and apparatus for duplexing transmissions on a communication link in wireless communication systems. Communication link efficient is enhanced by dynamically adapting to the uplink and downlink bandwidth requirements of the communication channels. Time slots are flexibly and dynamically allocated for uplink or downlink transmissions depending upon the bandwidth needs of a channel. Communication link bandwidth requirements are continuously monitored using sets of predetermined bandwidth requirement parameters. Communication channels are configured to have either symmetric or asymmetric uplink/downlink bandwidths depending upon the needs of the channel. Channel bandwidth asymmetry can be configured alternatively in favor of the uplink transmissions (i.e., more time slots are allocated for uplink transmissions than for downlink transmissions) or in favor of the downlink transmissions (i.e., more time slots are allocated for downlink transmissions than for uplink transmissions). A myriad of time slot allocation schemes are possible. One simplified time slot allocation scheme uses a “frame-based” approach. A preferred channel bandwidth analysis technique is disclosed which monitors and updates bandwidth requirement parameters associated with communication sessions, base stations and cell cluster controllers. In accordance with this technique, a communication session is preferably assigned both an “initial” and an “actual” set of bandwidth parameters.
