Abstract: Methods and apparatuses are provided for managing a list of target frequencies for cell measurement. A set of available target frequencies for performing cell measurements from a serving cell can be received, and at least a subset of the set of available target frequencies can be prioritized based at least in part on a list of a plurality of target frequencies stored in a reselection database for the serving cell. Cell measurements can be performed based at least in part on at least the subset of the set of available target frequencies as prioritized. Additionally, the plurality of target frequencies in the reselection database may correspond to target frequencies to which successful reselection has occurred from the serving cell.

Abstract: The present disclosure presents a method and an apparatus for inter-radio access technology (IRAT) background public land mobile network (BPLMN) re-acquisition mechanism at a user equipment (UE). For example, the method may include performing a BPLMN acquisition mechanism at a UE, checking whether a BPLMN re-acquisition mechanism is valid, determining whether the re-acquisition mechanism requirements are met, and performing the re-acquisition mechanism at the UE. As such, an IRAT BPLMN re-acquisition mechanism at a UE is performed.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate using a first antenna and a second antenna. The UE may detect an event associated with a component of the UE. The UE may switch a radio frequency (RF) chain from the first antenna to a third antenna based on the detection of the event. The UE may measure, using the second antenna and the third antenna, one or more signals to obtain one or more measurement values based at least in part on switching the RF chain from the first antenna to the third antenna. The UE may transmit a communication using the second antenna or the third antenna based on the one or more measurement values. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may determine a time-averaged power limit of a set of antennas. The apparatus may modify an antenna switching configuration based at least in part on the time-averaged power limit. The apparatus may transmit a signal using an antenna, from the set of antennas, associated with the modified antenna switching configuration, wherein the antenna is associated with a higher power limit than one or more other antennas. 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 a first communication, associated with a first subscriber identity module (SIM) operating in a connected mode, that is at least partially overlapping in a time domain with a second communication associated with a second SIM operating in an idle mode. The UE may detect that a transmit chain associated with the first SIM and a receive chain associated with the second SIM are sharing an antenna switch. The UE may perform a preventive action based at least in part on the first communication associated with the first SIM overlapping in the time domain with the second communication associated with the second SIM while the transmit chain associated with the first SIM and the receive chain associated with the second SIM are sharing the antenna switch. Numerous other aspects are described.
