摘要： Methods and apparatus for providing channel diversity to wireless terminals (WTs) in a manner that reduces the latency between the time a WT encounters satisfactory channel conditions are described. A plurality of communications channels with different physical characteristics are maintained in a cell by a base station (BS). Each WT monitors multiple channels and maintains multiple channel estimates at the same time so that rapid switching between channels is possible. Channel quality information is conveyed from each WT to the BS. The WT or BS selects a channel based on the measured channel quality. By supporting multiple channels and by introducing periodic variations into the channels in various embodiments, the time before a WT encounters a channel with good or acceptable channel conditions is minimized even if the WT does not change location. Multiple antennas are used at the BS to support numerous channels simultaneously, e.g., by controlling antenna patterns.

摘要： Provided is an feedback mechanism to correct power control information in a broadcast signal that is determined to be incorrect by one or more devices that receive and rely on the broadcast information. A device that receives the incorrect broadcast information can determine a correction and to the information and provide a recommendation to tilt source of the broadcast information. The source can selectively determine whether to modify the broadcast information based on the recommendation from one or more devices. If the broadcast information is modified, subsequent devices that receive the broadcast information are provided with the modified information. If further changes are needed, the subsequent devices can provide further recommended changes.

摘要： Systems and methodologies are described that facilitate dynamically adjusting scheduling priorities in relation to a combination of delay sensitive flows with delay requirements and best effort flows. The systems and methodologies provide optimal and efficient techniques to enable real time adjustment and assignment of bandwidth for a combination of best effort flows and delay sensitive flows. In particular, the bandwidth allocation is adjusted for each data packet such that delay requirements are met and the remaining bandwidth can be assigned to best effort flows.
