Abstract: Aspects of the methods and apparatus relate to performing call recovery after a call drop. A cell selection update procedure may be initiated to recover a call in response to the call being dropped with a serving cell. Link conditions may be determined for the serving cell and for different candidate cells. The aspects of the methods and apparatus also include selecting a cell, based on the link conditions, from among the serving cell and a candidate cell with a highest signal power parameter in a Primary Common Control Physical Channel (PCCPCH) across a set of neighboring frequencies of the different candidate cells. Call recovery may be performed using the selected cell. In some aspects, the highest signal power parameter may be a highest Received Signal Code Power (RSCP).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, during an ongoing data session on a first subscriber identity module (SIM), an incoming voice call on a second SIM. The UE may determine, during the ongoing data session on the first SIM, a caller identifier associated with the incoming voice call on the second SIM. The UE may initiate, on the first SIM, a communication to the caller identifier associated with the incoming voice call in concurrency with the ongoing data session. Numerous other aspects are described.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, via a first subscription of the UE, a trigger event for a conditional handover of the UE from a source network entity to a target network entity. The UE may determine, based at least in part on the trigger event, that a target band associated with the target network entity is not compatible with a serving band associated with a second subscription of the UE. The UE may store the trigger event for the conditional handover in a buffer of the UE. The UE may perform an action related to the conditional handover based at least in part on a condition being satisfied. 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 transmit, via a subscription of the UE to a network node, a UE assistance information (UAI) that indicates a reduction to one uplink multiple-input multiple-output (MIMO) layer for the subscription. The UE may transmit, via the subscription to the network node, an uplink transmission using one uplink MIMO layer on one transmit (Tx) chain of the UE based at least in part on the UAI and a timer associated with the UAI. 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 transmit, on a first subscriber identity module (SIM) operating in a connected mode, a signal using a first antenna associated with a first antenna module. The UE may configure, for a second SIM operating in an idle mode, a second antenna associated with the first antenna module for receive operations. The UE may switch a transmit antenna associated with the first SIM from the first antenna to a third antenna associated with a second antenna module based at least in part on configuring the second antenna for receive operations and based at least in part on the first antenna module being unable to support concurrent transmission and reception of signals. The UE may transmit, on the first SIM, a signal using the third antenna. Numerous other aspects are described.

Abstract: In some aspects, a user equipment (UE) may communicate using a first radio access technology (RAT) for a first subscription of the UE, wherein the first RAT is selected from a group that includes a first cellular RAT associated with the first subscription, a second cellular RAT associated with a second subscription of the UE, and a wireless local area network (WLAN) RAT. The UE may communicate using a second RAT for the second subscription of the UE, wherein the second RAT is selected from the group that includes the first cellular RAT associated with the first subscription, the second cellular RAT associated with the second subscription of the UE, and the WLAN RAT. The UE may transition, based at least in part on a condition, a communication link carrying a protocol data unit (PDU) session from the second subscription to the first subscription. Numerous other aspects are described.

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.
