    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) utilizing enhanced carrier aggregation (eCA) may identify a limit to the number of channel state feedback (CSF) processes it is capable of supporting. The UE may transmit an indication of this limit to a base station, which may configure the UE for channel state reporting, and send channel state reporting triggers according to the indicated limit. The UE's determination of the limit to the number of CSF processes may be based on various transmit or receive antenna configurations. A single trigger may correspond to reports covering multiple subframes and/or component carriers. The base station may also arrange the channel state reporting configuration to reduce the peak number of channel state reports that the UE processes during each subframe. The UE may also determine that a number of channel state processes needed to support channel state reporting in a subframe exceeds its capacity. The UE may then prioritize the channel state processes and/or may transmit one or more non-current reports.

    Abstract: Methods and devices for implementing dynamic receive mode management to improve data throughput and paging performance on a multi-subscriber identification module (SIM) wireless communication device may include detecting, on a protocol stack associated with a first SIM, an active communication in a first network, detecting, on a protocol stack associated with a second SIM, an idle mode paging cycle in a second network, prompting entry into a selected dual receive mode on the shared RF resource, and monitoring at least one performance metric for the idle mode paging cycle associated with the second SIM while in the dual receive mode. Based on the monitored performance metric while in the dual receive mode, the wireless communication device may determine whether paging performance is degraded for the second SIM, and if so, trigger entry into a fallback mode on the shared RF resource.

    Abstract: A method for wireless communication at a wireless device is disclosed herein. The method includes selecting a wideband precoder for a first set of antennas and a second set of antennas based on at least one matrix, where a number of the first set of antennas and the second set of antennas is greater than a maximum number of supported layers. The method includes calculating, based on the selected wideband precoder, a first set of performance metrics for the first set of antennas and a second set of performance metrics for the second set of antennas. The method includes combining the first set of performance metrics for the first set of antennas and the second set of performance metrics for the second set of antennas based on the calculation.

    Abstract: Methods, systems, and devices for wireless communications are described. One example includes calculating one or more first channel capacities for each precoder hypothesis of a first subset of precoder hypotheses and selecting a first precoder hypothesis of the first subset of precoder hypotheses using the calculated first channel capacities. The example also includes selecting a second subset of precoder hypotheses based on the first precoder hypothesis, calculating one or more second channel capacities for each precoder hypothesis of the second subset of precoder hypotheses, and selecting a second precoder hypothesis of the second subset of precoder hypotheses using the calculated second channel capacities. The example also includes selecting grouping co-phase factors based at least in part on the first precoder hypothesis or the second precoder hypothesis and transmitting a first precoding matrix indicator that indicates a first precoder index based on the one or more grouping co-phase factors.
