摘要： Methods and apparatus for wireless communications are described. A method of wireless communications includes determining an energy for a first signal received at a first finger of a rake receiver after a reference signal is received at a second finger of the rake receiver, determining an energy for a second signal received at a third finger of a rake receiver before the reference signal is received at the second finger of the rake receiver, and selecting the first signal as a new reference signal when the energy of the first signal exceeds the energy of the second signal by a predefined threshold amount. In another aspect, a method includes assigning a signal received at a rake receiver to a finger of the rake receiver, and deassigning the finger if the signal has an energy level below a preselected lock threshold energy for a predefined time.

摘要： Techniques for handling fingers with large delay spread through utility optimization are described. A first signal may be received, through a finger of a plurality of fingers in a receiver, at a time that is later than a reference time after a reference signal is received by a reference finger of the plurality of fingers. The reference signal may be included in an on-time group corresponding to a cell. The first signal may be included in a late group corresponding to a virtual cell. The first signal and the reference signal may be compared to one another. Based on the comparing, it may be determined whether to wait for additional signals in the late group or process the signals in the on-time group.

摘要： UEs are adapted to facilitate detection and handling of deconstructive impacts of default weight factors employed before downlink and uplink synchronization is achieved in closed-loop transmission diversity communications. According to one example, a UE may receive transmissions sent using a default weight factor for transmission diversity (402). The UE may determine whether the default weight factor is causing a deconstructive impact on signal- to-interference ratio estimates for the received transmissions (404). When it is determined that the default weight factor is causing the deconstructive impact on the signal-to-interference ratio estimates for the received transmissions, the UE may employ an alternate closed-loop transmission diversity (CLTD) mode (406). Other aspects, embodiments, and features are also included.

摘要： A slot in a frame of n frames is received at a user equipment (UE). Valid slots are detected based on a given validity criterion (602, 702). The valid slots are classified as outage slots if an estimated signal quality does not exceed an outage signal quality (620, 704). A total valid slot count and a total outage slot count are accumulated over an outer loop duration spanning a plurality of the slots (624, 706). The total outage slot count is compared to a preset ratio of the total valid slot count (630, 708). A target signal quality is updated based on the comparison (632 / 634, 710).

摘要： in order to improve a soft handover in a UMTS-CDMA/WCDMA network, detection and handling of a spurious Dedicated Physical Channel (DPCH) of a cell in an active set from a mobile station side. A user equipment determines a signal-to-interference ratio (SIR) for each channel of a plurality of channels associated with cells maintained in an active set and determines a spurious DPCH to be the lowest SIR among the plurality of channels. The user equipment puts the detected spurious DPCH in an exclusion mode in which the spurious DPCH is excluded from at least one of channel decoding or SIRE calculation, while maintaining the cell associated with the spurious DPCH in the active set.
