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: Various embodiments for managing carrier transmissions after a tune-away on a wireless communication device may include determining whether a network has received transmissions from a first carrier of a first subscription after completion of the tune-away from the first subscription to a second subscription. In response to determining that the network has not received transmissions from the first carrier, the wireless communication device may determine whether a second carrier of the first subscription is transmitting to the network after completion of the tune-away. In response to determining that the second carrier is not transmitting to the network, the wireless communication device may route transmission from the first carrier to the second carrier.

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: The present disclosure presents a method and apparatus for reducing power consumption during a voice communication in a user equipment (UE). For example, the method may include receiving a plurality of frames associated with the voice communication. Further, such an example method may include determining whether a frame pattern based at least on the received plurality of frames corresponds to a transition from a speech burst period to a non-speech period, and disabling a portion of a receiver subsystem at the UE for at least a portion of a frame associated with the non-speech period. As such, the power consumption in a UE may be reduced.

Abstract: Aspects of the present disclosure provide an apparatus and methods for operating the same that can improve out-of-sync and radio link failure handling in a W-CDMA network. A user equipment (UE) establishes a packet switched (PS) connection between the UE and a base station, wherein the PS connection includes a Fractional Dedicated Physical Channel (F-DPCH). The UE configures an in-sync threshold (Qin) and an out-of-sync threshold (Qout) for the F-DPCH, wherein values of the Qin and Qout are set higher than those of corresponding Qin and Qout of a Dedicated Physical Channel (DPCH). The UE further estimates a downlink (DL) Signal to Interference Ratio (SIR) based on one or more transmit power control (TPC) commands of the F-DPCH, and determines whether to release the PS connection based on a comparison of the estimated SIR and Qout of the F-DPCH.
