Abstract: Disclosed are systems and methods for controlling by the User Equipment (UE) downlink power in early decode termination mode. In one aspect, the UE may be configured to perform early decoding of a downlink (DL) transmission from a base station. The UE further configured to estimate a signal-to-interference ratio (SIRE) of the DL transmission. Based on the SIRE, the UE is configured to select a Transmission Power Control (TPC) command sequence for a low power mode of operation of the UE in which a receiver is powered down. The UE is further configured to activate the low power mode and transmit the selected TPC command sequence to the base station to adjust a DL transmission power during the low power mode.

Abstract: Aspects of the disclosure provide techniques for improving uplink transmit power control at a user equipment (UE). When the UE is communicating with multiple cells using Multi-flow High-Speed Downlink Packet Access (MF-HSDPA), the UE may control its uplink power based on an improved MF-HSDPA uplink power control algorithm, which is different from an or-of-downs (OOD) transmit power control. In handover, a UE may determine its transmit power to be less than a transmit power requested by a high-speed cell and more than an OOD transmit power.

Abstract: UEs are adapted to facilitate reconstruction of a segment of corrupted bits. According to one example, a UE can receive a control channel transmission such as a HS-SCCH transmission. The control channel transmission may include a plurality of information bits and a plurality of cyclic redundancy check (CRC) bits. The UE may further determine that a contiguous segment of the received information bits is corrupt. The UE may accordingly utilize the uncorrupted information bits and CRC bits to reconstruct the corrupt information bits. In some instances, the UE may utilize the uncorrupted bits to reconstruct the corrupt information bits using a new generator polynomial. In other instances, the UE may utilize the uncorrupted bits to reconstruct the corrupt information bits using the original generator polynomial. Other aspects, embodiments, and features are also included.

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.
