Abstract: Aspects of the methods and apparatus include determining that a time-to-trigger (TTT) timer has expired, and determining that a serving radio access technology (RAT) received signal characteristic is less than a signal characteristic threshold when the TTT timer has expired. Further, the aspects include determining, in response to the serving RAT received signal characteristic being less than the signal characteristic threshold, that a target RAT frequency measurement associated with a Measurement Report Message (MRM) for performing an inter-RAT (IRAT) handover cannot be completed within a time limit according to a current measurement gap configuration. Also, the aspects include calculating a measurement gap duration sufficient to complete the target RAT frequency measurement associated with the MRM for performing the IRAT handover, and configuring a new measurement gap prior to the time limit, wherein the new measurement gap comprises the calculated measurement gap duration.

Abstract: A method of wireless communication includes determining a threshold based on a signal strength of a strongest candidate target cell of a target radio access technology (RAT) and a previous serving cell of the target RAT. The method also includes pruning a list of candidate target cells of the target RAT based on the threshold. The list is pruned for a handover from a source RAT. The method further includes reporting the pruned list to a base station of the source RAT prior to the handover.

Abstract: A system acquisition is initiated to perform inter radio access technology (IRAT) measurement. A waiting period of time is provided before aborting the system acquisition. The period of time is adjustable based on at least one metric. The metric can be a frequency of available measurement gaps, a total number of available measurement gaps, and/or a length of each measurement gap within a subframe. The metric could also be an absolute signal strength of a single neighbor cell and/or a relative signal strength between neighbor cells. The metric could also be a user equipment (UE) measured signal strength compared to a network indicated threshold value for triggering an IRAT measurement report. The metric could also be a percentage of a tone that falls within a measurement gap.

Abstract: A user equipment (UE) may improve scheduling of inter radio access technology (IRAT) measurement during continuous data transmission, for example in a High Speed-Physical Downlink Shared Channel (HS-PDSCH). The UE may determine whether an IRAT measurement is desired. The UE may also perform the IRAT measurement during a scheduled downlink data subframe when it is determined the IRAT measurement is desired, without losing the scheduled downlink data.

Abstract: A method for of wireless communication, by a multi-subscription user equipment (UE) includes selecting a first subscription to receive a positioning system information broadcast (posSIB) based on a first subscription state and a second subscription state. The method also includes receiving the posSIB via the first subscription. The UE may switch from the first subscription to a second subscription to receive a subsequent posSIB, in response to the second subscription state changing and/or the first subscription state changing. The state switching may be between connected mode and inactive/idle mode, or between voice service and data service.

Abstract: Certain aspects of the present disclosure provide a technique for wireless communications by a user equipment (UE). The UE monitors a concurrent operation on multiple operating bands within a same subscriber identity module (SIM) or between multiple SIMs that involves sharing at least one radio frequency (RF) component. The UE enables or disables the at least one RF component based on the monitoring.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish one or more wireless connections for different subscriptions with a base station. The UE may receive an indication of a temporary mobile subscription identifier (TMSI) from the base station during a registration procedure. The UE may calculate a paging occasion (PO) based on the TMSI and may determine the PO fails to satisfy a threshold timing value. The UE may transmit one or more registration request to trigger additional registration procedures in which base station may transmit a new TMSI. The UE may calculate an updated PO based on the new TMSI. The UE may periodically receive one or more paging messages from the base station in a set of POs based on calculating the updated PO.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with two subscriber identity modules (SIMs). The UE may select a synchronization beam associated with a random access occasion of a first SIM based on the random access occasion not overlapping in time with a reception opportunity (e.g., a paging occasion) of the second SIM. In some examples, the UE may select the synchronization beam based on an identified signal quality of the synchronization beam (e.g., in comparison to other available synchronization beams that are non-overlapping with the reception opportunity). The UE may perform a random access procedure (e.g., using the first SIM) during the random access occasion associated with the selected synchronization beam and, in some cases, may also monitor (e.g., using the second SIM) resources associated with the paging opportunity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may detect that a voltage fails to satisfy a performance threshold while operating in a dual subscriber identity module (SIM)-dual active (DSDA) mode associated with maintaining a first network connection in a first active mode concurrently with maintaining a second network connection in a second active mode. The mobile station may transition the first network connection from the first active mode to a standby mode based at least in part on detecting that the voltage fails to satisfy the performance threshold. Numerous other aspects are described.
