Abstract: Aspects described herein relate to throttling packet-switched (PS) call establishment in wireless communications. A circuit-switched (CS) call can be conducted by using a first radio access technology (RAT). A cell update (CU) procedure for a PS call using a second RAT can be detected as due to one or more conditions. A cause for the one or more conditions can be determined based on one or more parameters related to a transmitter or receiver. PS call establishment attempts can accordingly be throttled based at least in part on determining the cause for the one or more conditions

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: A user equipment (UE) may adjust a time permitted for a UE to attempt blind handover after a first non-blind handover failure to efficiently establish connection with a second radio access technology (RAT) or re-establish connection with a first RAT to increase handover success rate. In some instances, the UE may dynamically adjust the time permitted for acquiring a target RAT cell based on a signal strength of a target cell of the target RAT and/or a signal strength of a serving cell of a serving RAT, after a synchronized handover failed.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain one or more parameters associated with a dual subscriber operation of the UE that includes communicating using a first subscriber entity and a second subscriber entity. The UE may transmit one or more uplink communications via one or more of the first subscriber entity or the second subscriber entity using a coexistence management configuration that is based at least in part on the one or more parameters. Numerous other aspects are described.

Abstract: A first network node (e.g., a UE) may receive, from a second BS network node (e.g., a base station), DCI. The first network node may perform, based on the DCI, a BWP switch from a first BWP to a second BWP. The first network node may perform, after the BWP switch, a BWP switch failure detection procedure that results in a first determination or a second determination. The first determination may be indicative that the BWP switch was successful and the second determination may be indicative that the BWP switch was not successful. To perform the BWP switch failure detection procedure, the first network node may determine whether one or more failure conditions are satisfied. The one or more failure conditions may include at least one of a BLER greater than a threshold, occurrence of one or more tune away events, or non-receipt of an uplink grant on the second BWP.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE starts a first timer (such as a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer), after sending an uplink (UL) data transmission to a network entity. The UE then starts a second timer (such as a DRX retransmission timer) when the first timer expires. The UE then determines whether to wake up or sleep for a duration of the second timer based on a prior block error rate (BLER).

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.
