    摘要: Methods and apparatus for an adaptive set management in a communication system are disclosed. Certain levels of an imbalance between a forward link and a reverse link are always present in a communication system. Although severe levels of an imbalance cause a detrimental effect on quality of communication and throughput, the imbalance is an issue only if it degrades throughput by one rate on the forward link. Consequently, an adaptive set management evaluates an imbalance among sectors in a subscriber station's list in accordance with the quality metric of the forward link and the reverse link, and removes from the subscriber station's list only a sector that causes severe imbalance. Although retaining a sector in the subscriber station's list may improve throughput, it may negatively affect other functions of the communication system, e.g., power control. Therefore, a method of power control is modified if a level of imbalance affecting the power control is detected.

    摘要: An access network determines to transmit multicast messages on a downlink shared channel. The access network receives a multicast registration message and a traffic channel request from at least one access terminal. The access network assigns a traffic channel to the at least one access terminal, and transmits the multicast messages on the downlink shared channel. In another example, the access network can determine a channel type upon which the support a multicast session, can indicate the channel type selection to the at least one access terminal in an announce message and can then transmit the multicast messages for the multicast session on the selected channel type. The at least one access terminal receives the announce message, requests a traffic channel and receives a traffic channel assignment, registers to the multicast session and monitors the downlink shared channel for multicast messages.

    摘要: Methods and apparatus for estimating maximum rate of data and for estimating a transmission power required for transmission of a data with a rate of data in a communication system are disclosed. A terminal determines a quality metric of a communication link, over which data are to be transmitted, and modifies the determined quality metric by a quality metric margin. The terminal then estimates the maximum rate of data in accordance with the modified quality metric. Alternatively, the terminal then estimates transmission power required for transmission of a data with a rate of data in accordance with the rate of data and the modified quality metric. The quality metric margin may be a pre-determined or dynamically adjusted. The terminal dynamically adjusts the quality metric margin in accordance with a result of comparison of a transmit power corresponding to the estimated maximum rate of data with an actual transmit power used to transmit the data.

    摘要: Method and a system method and system for a dynamic adjustment of a data request channel in a communication system are disclosed. A value of at least one variable affecting the data request channel margin is determined in accordance with conditions in the communication system. The at least one variable is then set to the determined value. The value of the at least one variable is then conveyed to a subscriber station in an adjustment message. The subscriber station determines whether the adjustment message was transmitted by a serving sector or a non-serving sector; and adjusts at least one attribute of the communication channel in accordance with the determination, thus adjusting the DRC channel margin.

    摘要: Aspects of mobility management within a wireless communications network including a plurality of sectors are disclosed. In an example, the wireless communications network includes a first cluster of sectors with at least one target sector and at least one supporting sector. The multicast communication session is carried within both the target and supporting sectors. In another example, a second cluster can be included within the network for supporting the same multicast communication session that includes its own target and supporting sectors. In this example, the first cluster transmits multicast media on a first interlace-multiplex (IM) pair of a downlink broadcast channel (BCH) and the second cluster transmits multicast media on a second IM pair of the downlink BCH. If sectors of the first and second clusters overlap, the network controls a manner in which the first and second clusters carry the multicast media.

    摘要: Broadly speaking, the invention comprises systems and methods that use the number of mobile stations, denoted by N, communicating with a base station, as a variable that determines the optimum induced change rate, R, and the antenna beam width, W, of a time-varying base station antenna gain pattern used in conjunction with a forward power modulation (FPM) or a similar scheme to maximize the overall data throughput from the base station by taking advantage of multi-user diversity. In one embodiment, the FPM scheme is turned off if N is below a lower threshold. If N is above this threshold, the FPM scheme is turned on with R and W set to appropriate values. Generally, higher values of N correspond to higher values of R and lower values of W.
