  • Publication number: 20140248920
    Abstract: Techniques for uplink transmit power command (ULTPC) rejection threshold optimization in WCDMA for power control algorithm 2 (PCA2) are described. Uplink transmit power control commands may be received on a five-slot interval. The uplink transmit power control commands may be decoded for each of the five slots. The decoded uplink transmit power control commands may be compared for each of the five slots to a threshold. The threshold may be optimized to minimize overall transmit power control decision error. A bit decision may be made for each of the five slots based on the comparison and an overall transmit power control command may be determined based on the bit decision for each of the five slots over the five-slot interval.

  • Publication number: 20140228026
    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.

  • Publication number: 20140080537
    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.

  • Publication number: 20140078946
    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.

  • Publication number: 20140078951
    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.

  • Publication number: 20130244647
    Abstract: Methods and apparatus of monitoring cells in a wireless communication system may include determining existence of a condition for performing a cell search on a frequency. In addition, the methods and apparatus may include calculating an undetected energy-related value for a hypothetical undetected cell based on a measured energy-related value of each detected cell on the frequency in response to determining the condition for performing the cell search. The methods and apparatus may further include determining whether to perform the cell search based on the undetected energy-related value and a reselection criteria.

  • Publication number: 20130012254
    Abstract: A particular method includes transmitting a message corresponding to a reporting event detected at a mobile device, where the reporting event is associated with a network condition that decreases a likelihood of the mobile device successfully decoding a reply to the message. The method also includes, in response to transmitting the message, increasing a signal-to-interference ratio (SIR) target of the mobile device.
