Abstract:
An apparatus, a method, and a computer program are disclosed, which can enable a wireless user equipment (UE) to reduce or avoid system losses, such as decode failures and the unavailability of page messages, which might otherwise result in a poor user experience. By way of example and not limitation, a UE may be configured to switch from a low-sensitivity receiver to a high-sensitivity receiver, or to a receive diversity configuration, when operating under poor channel conditions.
Abstract:
Apparatus and methods are disclosed for establishing a call utilizing a traffic channel corresponding to a first communication protocol; transmitting a data rate control (DRC) channel comprising a null cover for no greater than 16 time slots; tuning away from the call to receive signaling corresponding to a second communication protocol; and following the receiving of the signaling corresponding to the second communication protocol, tuning back to the traffic channel to resume the call.
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:
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 relate to methods and apparatus for saving power while performing radio access technology measurements. An exemplary method that may be performed by user equipment (UE) includes obtaining a configuration indicating a measurement gap for the UE to measure one or more non-serving cells, wherein the UE does not receive data transmissions from a serving cell during the measurement gap, deciding not to measure the non-serving cells during a period including at least a portion of the measurement gap, and deactivating a receive chain of the UE during the period.
Abstract:
In an embodiment, a user equipment (UE) determines an emergency health condition for a user that is defined based on a set of health-related parameters crossing a corresponding set of thresholds. The UE receives health data from a set of health monitoring sensors that are each configured to monitor one or more health-related parameters of the user. The UE detects, while a restricted mode restricting access to a set of communicative functions of the UE is active, that the emergency health condition for the user exists based on the received health data indicating that the set of health-related parameters have crossed the corresponding set of thresholds. The UE disables the restricted mode in response to the detecting. The UE conveys, using one or more communicative functions from the set of communicative functions that are made available by the disabling of the restricted mode, an alarm related to the detected emergency health condition for the user.
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.

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.
