Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, using a first subscription of the UE, a first communication connection associated with a first service. The UE may establish, using a second subscription of the UE, a second communication connection associated with a second service. The UE may operate in a dual subscriber identity module (SIM) dual active (DSDA) mode based at least in part on establishing the first communication connection and establishing the second communication connection. The UE may perform an action to maintain concurrent services, including the first service and the second service, while operating in the DSDA mode. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a first subscription, of a plurality of subscriptions associated with the UE, is associated with an active service on a first cellular network. The UE may search, for a second subscription of the plurality of subscriptions, for radio access technologies (RATs) and frequency bands that are compatible with a dual active mode of the UE. In some aspects, the UE may detect that the active service on the first cellular network has ended. Accordingly, the UE may search, for the second subscription, for RATs and frequency bands that are compatible with the dual active mode of the UE and for RATs and frequency bands that are incompatible with the dual active mode, before expiry of a timer associated with a power saving state. Numerous other aspects are described.

Abstract: The present disclosure relates to methods, devices and software that can be used for preventing damage to RF front end equipment used in wireless communication systems. In some aspects, a user equipment (UE) may establish a first communication having a first priority, wherein the first communication is associated with a first subscriber in a connected mode. The UE may establish a second communication having a second priority, wherein the second communication is associated with a second subscriber in the connected mode. The UE may identify a state of a transmit/receive (TRX) switch shared between the first communication and the second communication. The UE may perform, based at least in part on the state of the TRX switch, at least one of the first communication or the second communication using a TRX switching configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a first call associated with a first subscriber of the UE. The UE may establish a second call associated with a second subscriber of the UE, wherein the first subscriber and the second subscriber are active contemporaneously, and wherein the first call and the second call are associated with a first radio access technology (RAT). The UE may identify a mobility event that associated with an interruption to at least one of the first call and the second call, the mobility event involving switching the first subscriber to a second RAT. The UE may perform a mitigation action. Numerous other aspects are described.

Abstract: Aspects described herein relate to communicating, based on a first subscription, with a first Radio Access Technology (RAT) over a bandwidth part (BWP) in a set of one or more configured BWPs, tuning a transceiver away from the BWP to a second frequency to communicate, based on a second subscription, with a second RAT for a period of time, tuning, after the period of time, the transceiver back to a selected BWP to communicate with the first RAT, and handling BWP parameters during or based on the tune away or tune back.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a user equipment (UE). The apparatus determines that a first subscriber identity module (SIM) and a second SIM of the UE share a cross switch and determines whether to modify concurrent operation of the first SIM or the second SIM based, at least in part, on a determination that the first SIM and the second SIM of the UE share the cross-switch. The concurrent operation of the first SIM and the second SIM may include the first SIM performing SRS antenna switching and the second SIM performing an idle mode activity.

Abstract: Certain aspects of the present disclosure provide techniques for protecting shared low noise amplifiers by limiting transmission power. A method that may be performed by a user equipment (UE) includes determining that a transmission by the UE on a frequency band via a first radio access technology (RAT) overlaps in time with a period that the UE is configured to receive on the frequency band via a second RAT; and limiting transmission power on the first RAT during the period.

Abstract: An apparatus for wireless communication is provided. The apparatus is configured to obtain, based on a first mobile alert associated with a first subscriber identity module (SIM) being scheduled for broadcast from a first network, an indication of receiver resources assigned for receiving the first mobile alert associated with the first SIM. The apparatus is further configured to refrain, based at least in part on the indication, from receiving a second mobile alert associated with a second SIM scheduled for broadcast from a second network. The first mobile alert and the second mobile alert may be associated with messages from at least one of a CMAS or an ETWS.

Abstract: Certain aspects of the present disclosure provide techniques for using a message to update a user equipment (UE) radio capability. For example a method of wireless communication by a user equipment (UE) may include generating a tracking area update (TAU) message with an indication of a UE radio capability update, transmitting the TAU message, and detaching and reattaching the UE from a network if a UE capability inquiry is not received from the network or a capability mismatch between the UE and the network is detected.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a predicted tune-away for a set of voice frames. In some aspects, the user equipment may alter a vocoder rate from a first vocoder rate to a second vocoder rate that is less than the first vocoder rate based at least in part on determining the predicted tune-away for the set of voice frames. In some aspects, the user equipment may drop, in connection with an occurrence of the predicted tune-away, a subset of packets for a time period corresponding to the predicted tune-away. Numerous other aspects are provided.
