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.

Abstract: A system and method for reducing power consumption in a mobile communication device is disclosed. The device may have multiple subscriber identity modules (SIMs), wherein each SIM is associated with a subscription. The method may include measuring received signal strengths from one or more cells for use with a first subscription. The method may also include sharing the search results for use with a second subscription. The first subscription and the second subscription may be associated with the same or difference cells and radio access technologies. The method may also include refraining from measuring the received signal strengths of the one or more cells for use with the second subscription, based on the search results.

Abstract: Disclosed are an apparatus and method for power control biasing towards early decode success of voice calls. In an aspect, the apparatus and method are configured to measure a signal-to-noise ratio (SNR) of a downlink transmission; request a base station to increase transmit power at the start of a transmission time interval (TTI) for a downlink voice call transmission; demodulate one or more voice frames of the voice call transmission; performing early decoding of one or more demodulated voice frames; determine whether the early decoding was successful; when the early decoding was successful, terminate demodulation and decoding of the voice call transmissions and request the base station to decrease transmit power; and when the early decoding was unsuccessful, request the base station to decrease transmit power for the remainder of the voice call transmission.
