    摘要: Techniques for power control that avoids outer loop wind-up are disclosed. In one aspect, wind-up of a target power level is detected, and the target power level is modified in response. In another aspect, unwinding of the target power level is detected, after which the target power level is determined without considering wind-up. Various other aspects are also presented, including wind-up and unwinding detection procedures, and target power level modification procedures. These aspects have the benefit of reducing the time that transmit power exceeds that which is necessary, thus increasing system capacity and performance, and mitigating misallocation of system resources.

    摘要: Techniques to mitigate spikes in transmit power, by reducing the magnitude and/or duration of the spikes, are described. Initially, power control is performed in a normal manner and in accordance with a transmit power control (TPC) scheme. If a (e.g., upward) transmit power spike is detected, the power control is performed in a manner to mitigate the adverse effects of the spike and in accordance with another TPC scheme. An upward transmit power spike may be detected, e.g., if a predetermined number of consecutive TPC commands in the upward direction is obtained for increasing transmit power. The upward transmit power spike may be mitigated by limiting the transmit power, reducing the rate of transmit power adjustment in the upward direction, delaying and/or filtering TPC decisions used for transmit power adjustment, preventing upward adjustment of transmit power, and so on. Multiple states may be defined and used to facilitate power control with spike mitigation.

    摘要: In general, this disclosure describes techniques for demodulating wireless signals. In particular, the techniques of this disclosure dynamically select between two or more demodulators based on channel quality information measured over a plurality of measurement periods. For example, a wireless communication device (WCD) may switch from a first demodulator to a second demodulator when the channel quality information associated with the demodulators indicates a better channel quality for the second demodulator than the first demodulator for a consecutive number of measurement periods. As another example, the WCD may compute, for each measurement period, the difference between the channel quality information associated with each of the demodulators, sum the differences, and switch demodulators when the total accumulation of the differences exceeds a threshold.

    摘要: Techniques for controlling transmit power for a data transmission sent on multiple data channels, which may be intermittently active, are described. Each data channel is monitored for activity (e.g., based on an error correction code, received signaling information, received block energy, and so on) and deemed to be dormant or not dormant (e.g., based on the amount of elapsed time since activity was last detected on the data channel). A signal quality (SIR) target may be maintained for each non-dormant data channel and updated based on the status of received data blocks for the data channel. A final SIR target, used for power control of the data transmission, may be set to the highest SIR target among the SIR targets for the non-dormant data channels. The final SIR target may also be updated directly based on the status of received data blocks for the non-dormant data channels.

    摘要: Dynamically control of receive diversity switching in a user equipment (UE) is disclosed. By dynamically controlling the switching between enabling and disabling the receive diversity, power consumption in UEs, such as smart phones and other mobile devices may be reduced. Control is based, at least in part, on measurements for data activity performed by the UE. When the UE finds measurements that would suggest data activity, the UE will switch to enable a receive diversity state when conditions are available for the switch. Similarly, when the UE finds measurements that would suggest data inactivity, the UE will switch to disable the receive diversity state when conditions are available for the switch.
