摘要： Systems and methodologies are described that facilitate and effectuate power allocation schemes that reuse power allocation patterns amongst different carriers for sectors in the same cell and uses different power allocation patterns between cells. The frequency reuse scheme generates power allocation patterns, selects one of the generated power allocation patterns for use among at least two carriers of at least two sectors in a cell, and employs a second disparate power allocation pattern for use between at two cells.

摘要： The performance of closed loop transmit diversity (CLTD) systems may be improved, in accordance with aspects of the present invention, by encoding antenna control information fed back from a mobile station to a base station. As compared to prior art CLTD systems that send antenna control bits in unencoded feedback messages, encoding the antenna control information may result in reduced feedback delays and reduced transmission power. Further, in accordance with some aspects of the present invention, the antenna control bits may be fed back to the base station on a common feedback channel also used to feed back channel quality indication, thus reducing processing overhead.
摘要翻译：根据本发明的方面，通过将从移动台反馈的天线控制信息编码到基站，可以改善闭环发射分集（CLTD）系统的性能。与在未编码的反馈消息中发送天线控制位的现有技术的CLTD系统相比，对天线控制信息进行编码可能导致反馈延迟减小和传输功率降低。此外，根据本发明的一些方面，天线控制位可以在也用于反馈信道质量指示的公共反馈信道上反馈给基站，从而减少处理开销。

摘要： A method of controlling link transmission parameters of a communication flow in a network caches one or more network parameters at the end of a first communication flow for an elapsed time, and adjusts the network parameters for controlling link quality and transmit power of a next communication flow based on an uncertainty that is caused by caching for the elapsed time. The state of a communication channel during a previous communication flow (connection) is used to determine network parameters to use at a future communication flow. When a connection begins, and the network does not know the ideal settings to use, the network defines a specified, elapsed time duration over which the state of a previous connection no longer can be trusted, i.e., an uncertainty period. Network parameters are adjusted to account for uncertainty caused by the elapsed time.

摘要： In a wireless communication system, there is a method of transmitting over a reverse link, where a medium access control layer multiplexes data from upper level layers onto transport channels that are used based on whether the user is in a scheduled transmission mode or an autonomous transmission mode. The transport channels may be mapped to one or more physical channels associated with a particular transport channel, based on whether the transport channel is dedicated for use in the scheduled or autonomous mode.

摘要： Rather than transmitting a large full Broadcast-Multicast Services (BCMC) Parameters Message (BSPM) containing a full set of BSPM parameters pertaining to all active BCMC flows within a sector on an infrequent basis, smaller-sized differential or partial BSPMs are instead transmitted. Differential BSPMs contain updated information for existing flows or information for new flows, and because of their smaller size, can be transmitted more frequently than full BSPMs. A mobile terminal receiving a differential BSPM updates the flows with the information contained within the differential BSPM or adds the information contained within the differential BSPM for a new flow. Partial BSPMs divide the flow information contained in a large full BSPM over a plurality of smaller-sized partial BSPMs, which are separately and sequentially transmitted at different times. A mobile terminal receiving these partial BSPMs then reconstructs the full BSPM from a collection of received partial BSPMs.
摘要翻译：而不是发送一个大量的完整的广播 - 组播服务（BCMC）参数消息（BSPM），其中包含与不频繁的扇区内的所有活动BCMC流有关的全套BSPM参数，更小尺寸的差分或部分BSPM被传输。差分BSPM包含用于新流的现有流或信息的更新信息，并且由于其较小的尺寸可以比全BSPM更频繁地传输。接收差分BSPM的移动终端用包含在差分BSPM内的信息更新流，或者添加包含在差分BSPM中的信息用于新流。部分BSPM将多个较小尺寸的部分BSPM中的大型完整BSPM中包含的流信息进行划分，这些BSPM在不同时间是单独依次发送的。接收这些部分BSPM的移动终端然后从接收的部分BSPM的集合中重构完整BSPM。

摘要： Methods and apparatus for communicating information using a plurality of report dictionaries are described. A plurality of request dictionaries are implemented for a wireless terminal to use for multi-bit uplink transmission backlog request reports communicated via the dedicated control channel. Each dictionary defines a different bit mapping interpretation for a set of multi-bit uplink transmission backlog request reports, e.g. a 3 bit uplink request report and a 4 bit uplink request report. The plurality of request dictionaries includes a default dictionary and additional dictionaries. The implementation of a plurality of alternative request dictionaries expands the reporting possibilities allowing a wireless terminal to use a reporting format well-suited to its current needs. The default dictionary is mandated to be used under certain predefined conditions, e.g., upon entry into the active state. Rules for transitioning between different dictionaries and continuing to use a selected dictionary are described.

摘要： Methods and apparatus related to the implementation and selection of alterative control information reporting formats are described. A control information reporting format, corresponding to a connection between a wireless terminal and a base station, e.g., for an uplink dedicated control channel, is selected, as a function of at least one of: an application being executed, device capability information, channel condition information, system loading information, and user quality of service information. Different wireless terminals may use different control information reporting formats at the same time. The same wireless terminal may use a different control information reporting format at different times.
