  • Patent number: 10278232
    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.

  • Patent number: 9930722
    Abstract: Various aspects of the present disclosure provide for conditionally disabling discontinuous reception (DRX). For example, DRX may be disabled if there is a loss of DRX synchronization, a loss of signal radio bearer traffic, a poor radio frequency condition, a low signal-to-interference ratio estimate, a low transmit power condition, or a drop in transmit power. Various aspects of the present disclosure provide for determining that an access terminal and the network are not in synchronization (e.g., DRX synchronization), and attempting to re-synchronize the access terminal and the network. In cases where a loss of DRX synchronization involves one entity having DRX enabled while another entity has DRX disabled, DRX may be temporarily disabled until synchronization is restored. In cases where a loss of DRX synchronization involves different entities using different subframe indices, the subframe index used by one of the entities may be changed to restore synchronization.

  • Patent number: 9706421
    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.

  • Patent number: 9521655
    Abstract: Methods and apparatus for avoiding power scaling and controlling transmit power in uplink data transmission are provided. If a user equipment (UE) would be transmit-power limited when transmitting data concurrently on an uplink high speed dedicated physical control channel (HS-DPCCH) and an uplink data channel, the UE may forgo building data for transmission on the uplink data channel to avoid power scaling. If the UE would be transmit-power limited when transmitting data concurrently on an HS-DPCCH and a dedicated physical control channel (DPCCH), the UE may reduce the transmission power of a portion of the data transmitted on the DPCCH to avoid power scaling. The UE may also boost transmission power of a negative acknowledge transmission above network-specified power level.

  • Patent number: 9179418
    Abstract: Aspects of the methods and apparatus relate to improving the overall decision quality of the Fractional-Dedicated Physical Channel (F-DPCH) channel. One aspect of the methods and apparatus relates to detecting bad channel conditions of a serving base station and improving the serving base station F-DPCH decoding performance in such bad conditions based on the serving base station signal-to interference ratio (SIR) estimation. Another aspect of the methods and apparatus relate to improving the overall decision quality of the F-DPCH channel in soft handover (HO) scenarios by increasing the non-serving base station F-DPCH channel rejections thresholds based on certain SIR estimations. The F-DPCH channel rejections thresholds are based on either the SIR of the non-serving base station, or a difference between non-serving base station SIR and serving base station SIR.

  • Patent number: 9148832
    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: 20150181495
    Abstract: Methods and apparatuses for wireless communication and cell monitoring and handover using a downlink dedicated physical channel (DL-DPCH) traffic-to-pilot ratio (TPR) are presented. For example, a method of mobile communication at a user equipment (UE) is presented, which may include starting a time-to-trigger (TTT) interval associated with a neighbor cell in preparation for potential handover of the UE to the neighbor cell according to network-assigned parameters. In addition, the example method may include monitoring a TPR associated with a DL-DPCH of a serving cell of the UE. Furthermore, the example method may include determining that the TPR exceeds a TPR threshold and shortening the TTT interval upon that determination. Moreover, the example method may include transmitting, based on the shortened TTT interval, a Measurement Report Message (MRM) to a network to add the neighbor cell to an active set associated with the UE.
