Abstract: Methods, systems, and devices for wireless communications are described. Some user equipment (UE) may be equipped with multiple subscriber identity modules (SIMs). A multi-SIM UE may receive a control message at a first SIM which indicates a set of sounding reference signal (SRS) resources for receiving SRS according to a first periodicity. The UE may also receive a registration message at a second SIM which includes a first parameter indicating a first set of paging occasions for receiving paging messages in accordance with a second periodicity. The UE may identify a collision in time between the one or more SRS resources and paging resources, and may transmit a registration request message to a base station. The UE may then receive a second registration message which includes a second parameter for calculating a second set of paging occasions that have a third periodicity that are non-overlapping with the SRS resources.

Abstract: Certain aspects of the present disclosure provide techniques for uplink transport protocol acknowledgment shaping and downlink data shaping at a user equipment. A method that may be performed by the UE generally includes determining an allowed number of transport protocol acknowledgments to transmit in a transmission time interval (TTI); and transmitting one or more transport protocol acknowledgments in the TTI based, at least in part, on the determined allowed number of transport protocol acknowledgments. Another method that may be performed by the UE generally includes determining an allowed number of downlink data units to transmit in a TTI; and transmitting one or more data units in the TTI based, at least in part, on the determined allowed number of data units.

Abstract: Methods, systems, and devices for wireless communications are described to support monitoring for paging messages from a base station (e.g., a cellular network node) using a greater periodicity than a discontinuous reception (DRX) cycle periodicity. A UE may monitor for and receive paging messages from a network node using a first subscription registered with a first radio access technology (RAT) while operating in DRX mode for a second RAT associated with the base station. The UE may identify a first periodicity for monitoring for paging messages from the base station that is greater than the DRX periodicity. The UE may have a second subscription that may be registered with a second base station. The UE may perform a tuneaway procedure from the second base station and monitor for paging messages from the base station according to the first periodicity.

Abstract: Aspects of the disclosure are related to a method, apparatus and system for adjusting a processing bandwidth or frequency domain buffer decimation associated with reference signals, for example, positioning reference signals (PRS). By reducing the number of, for example, resource blocks and/or resource elements to be processed, the power involved in processing the reference signal can be reduced. Hence, in some implementations, aspects of the disclosure can enable low-power low-bandwidth devices, such as NarrowBand Internet of Things (IoT) (NBIoT), to decode reference signals such as PRS.

Abstract: This disclosure provides systems, methods, and apparatus for receiving paging messages in fast fading scenarios. In one aspect, a method of demodulating a paging message during an assigned time slot by a wireless communications apparatus operating in an idle mode is provided. The method includes determining, in anticipation of the assigned time slot, an expected time position corresponding to a path of a pilot signal having a greater signal strength relative to other pilot signals. The method further includes assigning a first demodulation element to demodulate the pilot signal with reference to the expected time position and assigning a second demodulation element to demodulate the pilot signal with reference to a time offset from the expected time position. Other aspects, embodiments, and features are also claimed and described.
