摘要： Certain aspects of the present disclosure relate to communication systems, and more particularly, to improving performance for sounding reference signal (SRS) antenna switching in carrier aggregation (CA). A method is provided, that may be performed by a user equipment (UE) for wireless communications. The method includes determining one or more band combinations that share an antenna switch and sending a list of one or more bands in the one or more band combinations to a base station (BS). The BS receives the list and schedules the UE based on the received list.

摘要： Some aspects described herein reduce the negative performance impact associated with the voltage droop of a user equipment (UE) battery. For example, aspects described herein may be used to configure a UE with a pattern that includes a battery recovery time period that prevents a battery voltage of the UE from falling below a critical threshold and/or reduces the likelihood of the battery voltage falling below the critical threshold. In this way, UE performance may be improved, battery performance may be improved, battery life may be extended, and/or the like.

摘要： Certain aspects of the present disclosure provide techniques for capability information for sounding reference signal (SRS) improvements. An exemplary method generally includes determining a capability of the UE related to additional sounding reference signal (SRS) transmissions in a normal uplink (UL) subframe; transmitting, to a base station (BS), capability information indicating the determined capability of the UE; receiving SRS configuration information, wherein the SRS configuration information is based, at least in part, on the capability information; and transmitting at least one SRS in accordance with the SRS configuration information.

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

摘要： Certain aspects of the present disclosure provide techniques for handling collisions between PUSCH and sounding reference signal (SRS) on additional SRS symbols in an uplink subframe using carrier aggregation. The techniques provide rules that a user equipment (UE) may apply to decide if and when to drop or apply power scaling to SRS or PUSCH transmissions scheduled on overlapping time resources.

摘要： 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.

摘要： A method and system for managing electrical current within a portable computing device (“PCD”) includes assigning a priority to two or more communications supported by the PCD. A present level of a power supply for the PCD may be monitored by a communications power (“CP”) manager module. Next, the CP manager module may determine if the two or more communications may be transmitted at the present level of the power supply. If the two or more communications cannot be transmitted at the present level of the power supply, then the CP manager module may determine if a timing of at least one of the communications may be adjusted. The CP manager module may also determine a theoretical power level adjustment for at least one of the communications. The two or more communications may be transmitted with any calculated timing off sets and power level adjustments.
