    Abstract: In a wireless communication system (10) having a composite transport channel made up of individual transport channels, a method for closed loop power control wherein multiple instances of the outer loop are performed in parallel. The method determines a Signal-to-Interference Ratio (SIR) threshold for the composite channel based on a channel quality metric evaluated for each of the individual channels. In one embodiment the channel quality metric is a Cyclical Redundancy Check (CRC) outcome.

    Abstract: A method and apparatus for determining an operational mode for use in a wireless communication system based on a location, a velocity, or both, of a wireless communication device (WCD) in relation to a wireless network infrastructure is described. The selected mode can be used by various devices within the communication system. Modes that are selected include transmit diversity and site selection diversity.

    Abstract: A method and apparatus for using information about a mobile terminal's location relative to a base station can improve performance of a communication system. In addition, information about the mobile terminal's velocity relative to the base station may be used to improve performance of the communication system. The location information may be used to estimate a nominal PN offset, and a set of PN offset to use, for processing communication signals. The velocity information may be used to estimate a nominal frequency of the communication signals.

    Abstract: Techniques for tracking closely spaced multipath and preventing finger merge without monitoring relative positions between each of a plurality of fingers are disclosed. In one aspect, motion limits are determined for each finger. Time-tracking commands that would move the position of a finger outside its respective motion limits are suppressed. In another aspect, motion limits are updated dynamically, the motion limits of each finger determined in accordance with the motion limits of fingers adjacent to it. Various other aspects are also presented. These aspects have the benefit of preventing finger merge, which allows the allocation of multiple fingers to closely spaced multipath, thus increasing performance and system capacity, and mitigating misallocation of system resources.
