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: Methods and apparatus for wireless communication for improving the call performance and power consumption during the connection state of a user equipment (UE). Aspects of the methods and apparatus relate to receiving a transmit power control (TPC) command from a network entity and decoding every TPC slot of the TPC command. Aspects of the methods and apparatus include ceasing the decoding of a TPC slot set when the current decoded symbol of the TPC slot is in disagreement with the previous decoded symbol of the TPC slot. The receiver of the UE is then deactivated until the end of the TPC slot set.

Abstract: Disclosed are methods and apparatus for reducing UE's power consumption by controlling early decoding boundary. In one aspect, a UE is configured to receive a data or voice frame from a base station. The UE selects one or more quality metrics for determining decoding boundary of the received frame and computes the selected one or more quality metrics. The UE then determines a decoding boundary for the frame based on one or more computed quality metrics. The UE then decodes the received frames at the determined decoding boundary and determines whether the decoding of the frame was successful. If the early decoding of the frame was successful, the UE may terminate reception of the frame. If the early decoding of the frame was unsuccessful, the UE may adjust the decoding boundary and decodes the frame at the adjusted boundary.

Abstract: One or more aspects of the present disclosure aim to enable a reduced call drop rate and/or improved call performance in calls using 3GPP Release 99 Dedicated Physical Channel (DPCH) signaling, while reducing, or at least not causing a substantially large rise in power consumption at a wireless device, by utilizing selection diversity at a receiver. According to an aspect of the disclosure, a UE invokes a measurement period for detecting a downlink dedicated control channel (DCCH) based on a condition of a radio channel, during an initial portion of a transmission time interval (TTI). The UE samples one or more characteristics of a radio channel utilizing one or more of a plurality of receive chains. If the DCCH is detected during the measurement period, the UE selects one or more receive chains from among the plurality of receive chains in accordance with the one or more sampled characteristics. The UE receives a downlink transmission utilizing the selected one or more receive chains.
