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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may adjust an amplifier of the UE to a highest gain state after a downlink period and before an uplink period. Additionally, the UE may adjust the amplifier of the UE to a lower gain state after the uplink period and before a subsequent downlink period. Numerous other aspects are described.

Abstract: A user equipment (UE) includes: a first subscriber identity module (SIM) associated with a first service provider subscription and a second SIM associated with a second service provider subscription; the US is configured to operate the first service provider subscription in an active-mode and operating the second service provider subscription in an idle mode; and the UE is further configured to signal a changing quantity of multiple input, multiple output (MIMO) layers available to the first service provider subscription in response to radio frequency (RF) resource sharing with the second service provider subscription for a paging operation of the second service provider subscription.

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: A method of wireless communication performed by a user equipment (UE), the method including: operating in a mode in which a first subscriber identity module (SIM) is designated as a default data subscription (DDS) and a second SIM is designated as a non-default data subscription (nDDS), including the first SIM being active and the second SIM being idle; determining positions of uplink symbols and downlink symbols within a slot format of the first SIM; causing a hardware switch of the UE to couple the second SIM to an antenna of the UE during a first symbol that is configured as uplink or flexible; and performing a page decode operation by the second SIM while the second SIM is coupled to the antenna.

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: Various features related to reducing power consumption by devices during discovery periods D2D communication system, are described. In an aspect, a transmission pattern learning based intelligent monitoring approach is used. In certain configurations, an apparatus, e.g., a UE, may be configured to monitor, during a first set of discovery periods, transmissions of a plurality of different PACs associated with different applications, and identify PACs of interest from the plurality of different PACs. In some configurations, the apparatus maybe further configured to identify, based on the monitoring, transmission patterns of the PACs of interest, and monitor, during a second set of discovery periods, transmissions corresponding to the PACs of interest based on the identified transmission patterns. In some configurations, the PACs of interest monitored during the second set of discovery periods may be a subset of the plurality of different PACs monitored during the first set of discovery periods.

Abstract: The disclosure provides for monitoring neighbor cells while in an offline idle mode. A wireless device monitors cells during a periodic monitoring cycle while in the offline idle mode. In particular, the wireless device monitors the cells by classifying each cell of a list of neighbor cells as one of a first type of neighbor cell having valid overhead information stored in a cache and a second type of neighbor cell that is not associated with valid overhead information stored in the cache. The wireless device selects a monitoring set including an active cell and a subset of the neighbor cells including a cell of the second type of neighbor cell. The wireless device performs a pilot search of the monitoring set, during a periodic monitoring cycle while in a first idle mode state, to determine a signal strength of each cell in the monitoring set for a cell change.
