    Abstract: Various aspects of the present disclosure provide for conditionally disabling discontinuous reception (DRX). For example, DRX may be disabled if there is a loss of DRX synchronization, a loss of signal radio bearer traffic, a poor radio frequency condition, a low signal-to-interference ratio estimate, a low transmit power condition, or a drop in transmit power. Various aspects of the present disclosure provide for determining that an access terminal and the network are not in synchronization (e.g., DRX synchronization), and attempting to re-synchronize the access terminal and the network. In cases where a loss of DRX synchronization involves one entity having DRX enabled while another entity has DRX disabled, DRX may be temporarily disabled until synchronization is restored. In cases where a loss of DRX synchronization involves different entities using different subframe indices, the subframe index used by one of the entities may be changed to restore synchronization.

    Abstract: Method carried out in a wireless user equipment (UE), and corresponding UE, for lowering the vulnerability of a call to being dropped by assuring sufficient cell diversity in the active set of the UE when the value of the traffic-to-pilot ratio (TPR) exceeds a certain threshold, the method including: starting a time-to-trigger (TTT) interval associated with a neighbor cell in preparation for potential handover of the UE to the neighbor cell according to network- assigned parameters, monitoring a TPR associated with a DL-DPCH of a serving cell of the UE, determining that the TPR exceeds a TPR threshold, shortening the TTT interval upon that determination and transmitting, based on the shortened TTT interval, a Measurement Report Message (MRM) to a network to add the neighbor cell to an active set associated with the UE.

    Abstract: Aspects of the disclosure are directed to estimating a signal to interference ratio. A signal energy estimate corresponding to a received data transmission is generated. A noise to interference ratio estimate corresponding to the received data transmission is generated. A bias, corresponding to the noise to interference ratio estimate, is subtracted from the signal energy estimate. A signal to interference ratio estimate is determined corresponding to the signal energy estimate less the bias, and the noise to interference ratio estimate.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may obtain a measurement of a radio condition from a radio frequency signal received at a first antenna and enable receive diversity for further measurements of the radio condition when a metric of the radio condition does not meet a predefined threshold value. A probability of occurrence of an out-of-service state may be reduced by measuring the radio condition using further measurements using receiver diversity. The further measurements of the radio condition may be based on whether one version of the signal has greater energy than the other versions of the signal. The further measurements of the radio condition may obtained by combining received versions of the signal utilizing combination diversity to obtain a combined signal strength/energy.

    Abstract: Aspects of the methods and apparatus relate to improving the overall decision quality of the Fractional-Dedicated Physical Channel (F-DPCH) channel. One aspect of the methods and apparatus relates to detecting bad channel conditions of a serving base station and improving the serving base station F-DPCH decoding performance in such bad conditions based on the serving base station signal-to interference ratio (SIR) estimation. Another aspect of the methods and apparatus relate to improving the overall decision quality of the F-DPCH channel in soft handover (HO) scenarios by increasing the non-serving base station F-DPCH channel rejections thresholds based on certain SIR estimations. The F-DPCH channel rejections thresholds are based on either the SIR of the non-serving base station, or a difference between non-serving base station SIR and serving base station SIR.
