  • Apparatus and method for triggering a maximum power reporting event in a wireless communication network
    Patent number: 9491709
    Abstract: Aspects of the present disclosure provide an apparatus and method of utilizing a filtered transmit power margin calculation, rather than an instantaneous Tx power, to determine whether or not to trigger an Event 6D report. The filtered transmit power margin may take into account not only the user equipment's transmit power and the maximum transmit power level, but in addition, a received maximum power reduction value.

    Publication number: 20160315744
    Abstract: Aspects of mitigating throughput degradation during wireless communication include determining that a first transmission signal fails decoding at a network entity due to transmit (TX) blanking when a user equipment (UE) supports dual subscriber identity module dual active (DSDA) and is operating in hybrid automatic repeat request (HARQ) with incremental redundancy; determining whether a first retransmission signal for the first transmission signal fails decoding at the network entity; and retransmitting the first transmission signal as a new transmission signal when a determination is made that the first retransmission signal for the first transmission signal fails decoding at the network entity.

  • Determining a gain factor for transmit power control in enhanced uplink
    Patent number: 9456426
    Abstract: A gain factor is used for calculating one transmit power relative to another transmit power. For example, in UMTS high speed uplink packet access, a gain factor called ?ed is employed for transmission associated a given enhanced transport format combination indicator (E-TFCI). Conventionally, a gain factor to be used for a given E-TFCI can be determined via interpolation between two of the reference E-TFCIs to reduce signaling overhead. However, certain network configurations may result in one or more of the reference E-TFCIs that could be otherwise be used according to conventional techniques being outside of a valid range. In the event such a sub-optimal configuration occurs, interpolation and/or extrapolation schemes based on at least one reference E-TFCIs that is within and/or or is not within the valid range are used to calculate a gain factor for a given E-TFCI.
