Abstract: The present disclosure presents a method and an apparatus for inter radio access technology (IRAT) cell reselection. For example, the method may include identifying that a user equipment (UE) in an idle or a discontinuous reception (DRX) mode is camped on a cell of a first RAT, determining that the cell the UE is camped on is not broadcasting any neighbor cell of a second RAT, scanning for one or more frequencies of the second RAT based on the determination, and triggering a cell reselection to a cell of the second RAT, wherein the cell of the second RAT is associated with a frequency identified during the scanning. As such, an autonomous IRAT cell reselection may be achieved.

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 a dual network link scenario, a wireless network may provide a user equipment (UE) with a measurement configuration indicating multiple inter-frequency measurement objects during an off duration of a discontinuous reception (DRX) cycle configured on a first network link. The UE may assign the inter-frequency measurement objects to a second network link if the second network link has an always-on configuration. Alternatively, if the second network link has a DRX configuration, the UE may perform some inter-frequency measurement activities on the first network link and assign some inter-frequency measurement objects to unoccupied gap occasions in the off duration for the DRX cycle configured on the second network link. In this way, the UE may save power by spending more time in a low power state, and mobility performance for the UE may be improved by increasing the efficiency and reliability of inter-frequency measurement activities.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate on a primary carrier using a first antenna port. The UE may communicate on a secondary carrier using a second antenna port. The UE may determine whether to switch the secondary carrier from the second antenna port to the first antenna port based on a channel condition associated with the second antenna port. The UE may switch the secondary carrier from the second antenna port to the first antenna port based on a determination to switch the secondary carrier from the second antenna port to the first antenna port. Numerous other aspects are provided.

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: For a user equipment in a transmitter sharing dual subscriber identity module (SIM) dual active subscriptions (DSDA) mode, a first subscription of a first radio access technology (RAT) in a packet switched data call in general has a lower priority than a second subscription in an active voice call in a second RAT. As a result of this default high priority assigned to the active voice call, the first subscription may experience long delay, low throughput or in some cases radio link failure due to long starvations. A method for wireless communication includes detecting whether an uplink transmission within a frame of the second RAT overlaps at least one time slot of the first RAT. The method also includes prioritizing data of the first RAT by blanking the frame of the second RAT when a number of overlapping slots is above a threshold.

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
