Abstract: Disclosed are methods and apparatus for rejecting unreliable downlink (DL) transmit power control (TPC) commands based on signal-to-interference-ratio estimates (SIRE). The method includes receiving by a user equipment (UE) a DL transmit power control (TPC) command from a base station; calculating a signal-to-interference ratio estimate (SIRE) for the DL channel; determining a scaling factor for a DLTPC rejection threshold based on the DL channel SIRE; adjusting the DLTPC rejection threshold based on the determined scaling factor; and rejecting or accepting the DLTPC command based on the adjusted DLTPC rejection threshold.

Abstract: 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.

Abstract: Techniques are provided to control the transmit power for data transmission on multiple transport channels having different signal quality (SIR) targets. A single SIR target is maintained for all transport channels, and this SIR target is adjusted based only on active transport channels. For each update interval, a data processor processes at least one data block received in the current update interval on at least one of the transport channels and provides the status of each received data block. A controller increases the SIR target based on an up step if any received data block is erased and decreases the SIR target based on a down step if all received data blocks are good. If any received data block is erased, the down step used to adjust the SIR target may be set to the smallest down step size required by all transport channels with erased data blocks.

Abstract: Techniques to quickly adjust an SIR target toward a final value needed to achieve a specified target BLER for a data transmission. The outer loop may be implemented with multiple modes. The SIR target may be maintained fixed in a hold mode, adjusted in large down steps to speed up convergence in an acquisition mode, and adjusted by a small down step and a large up step for good and erased blocks, respectively, in a tracking mode. Various schemes may be used to adjust the SIR target by larger down steps in the acquisition mode. These schemes may be used even if data is transmitted intermittently, the target BLER is set to a low value, and/or one or multiple transport channels are used for data transmission. The SIR target may be boosted by a particular amount upon transitioning from the acquisition mode to the tracking mode.

Abstract: Techniques for performing equalization at a receiver are described. In an aspect, equalization is performed by sub-sampling an over-sampled input signal to obtain multiple sub-sampled signals. An over-sampled channel impulse response estimate is derived and sub-sampled to obtain multiple sub-sampled channel impulse response estimates. At least one set of equalizer coefficients is derived based on at least one sub-sampled channel impulse response estimate. At least one sub-sampled signal is filtered with the at least one set of equalizer coefficients to obtain at least one output signal. One sub-sampled signal (e.g., with largest energy) may be selected and equalized based on a set of equalizer coefficients derived from an associated sub-sampled channel impulse response estimate. Alternatively, the multiple sub-sampled signals may be equalized based on multiple sets of equalizer coefficients, which may be derived separately or jointly. The equalizer coefficients may be derived in the time domain or frequency domain.

Abstract: An apparatus, system, and method efficiently manage transmission power in a user equipment (UE) device by maintaining and applying an authorized power level to determine a transmission power level after a power limited transmission and before a new power control command has been received. The UE device maintains the authorized power level by monitoring and adjusting the authorized power level based on received power control commands. After a power limited transmission where the maximum power level is less than the authorized power level, the UE device determines the transmission power level for the next transmission based on the authorized power level. Accordingly, after the power limiting situation has ceased, the UE device transmits at the optimum power level eliminating the inefficiencies of transmitting at a lower than authorized power before the next power control command is received.
