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: Methods and apparatus for avoiding power scaling and controlling transmit power in uplink data transmission are provided. If a user equipment (UE) would be transmit-power limited when transmitting data concurrently on an uplink high speed dedicated physical control channel (HS-DPCCH) and an uplink data channel, the UE may forgo building data for transmission on the uplink data channel to avoid power scaling. If the UE would be transmit-power limited when transmitting data concurrently on an HS-DPCCH and a dedicated physical control channel (DPCCH), the UE may reduce the transmission power of a portion of the data transmitted on the DPCCH to avoid power scaling. The UE may also boost transmission power of a negative acknowledge transmission above network-specified power level.

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.

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.
