Abstract: The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing robust receive (Rx) processing to resolve radio frequency coexistence interference between two subscriptions operating on the DSDA device. The DSDA device may detect when a subscription (the “aggressor”) de-senses the other subscription (the “victim”) as a result of the aggressor's transmissions, and in response, implement robust Rx processing to mitigate the effects of de-sense on the victim while causing minimal impact to the aggressor.

Abstract: Disclosed are methods and apparatus for initializing an equalizer in a diversity receiver. In one aspect, the initialization includes estimating a channel impulse response (CIR) for each receiver chain of the diversity receiver; determining noise power estimates for each receiver chain based on the CIRs; and adaptively adjusting equalizer taps of each receiver chain based on the noise power estimates. In one aspect, the adaptive adjusting of the equalizer taps is based on scaling the CIR and covariance metrics for the receiver chain with higher noise power by a scale factor determined from the noise power estimates. In another aspect, the adaptive adjusting of the equalizer taps is based adaptive conditioning on the diagonal of the covariance matrix.

Abstract: Various aspects of the disclosure provide a method of operating a user equipment (UE) to determine and report a throughput enhancing channel quality indicator (CQI) value when a physical channel between the UE and a base station is temporally uncorrelated. Reporting such CQI value may maximize the throughput of the channel when it remains temporally uncorrelated. In one aspect of the disclosure, the UE communicates with a base station utilizing a channel and determines that the channel is temporally uncorrelated. The UE further determines a plurality of CQIs in a first CQI reporting mode and computes the respective throughputs of the channel based on the plurality of CQIs. In addition, the UE selects a CQI of the plurality of CQIs corresponding to the highest throughput among the plurality of throughputs, and reports the selected CQI to the base station in a second CQI reporting mode while the channel remains temporally uncorrelated.

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.

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.
