Abstract: Certain aspects of the present disclosure provide techniques for signaling and scheduling to enable network configured small gaps in intra-band inter-frequency measurement. A method that may be performed by a user equipment (UE) includes receiving, from a serving cell operating on a first frequency, an indication that synchronization signal block (SSB) indexes of a target cell operating on a second frequency can be derived from timing of the serving cell; and deriving an SSB index of the target cell, based on the timing of the serving cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a parameter associated with a secondary cell group. The UE may perform an optimization response action for a dual connectivity mode of a first frequency parameter or a second frequency parameter when the parameter satisfies a threshold, wherein the optimization response action is associated with whether the secondary cell group is operating with the first frequency parameter or the second frequency parameter. Numerous other aspects are described.

Abstract: Aspects are provided which allow a UE to disable measurements of reference signals from 5G base stations which are inapplicable to EN-DC. The UE may receive a reference signal from a base station. The UE may identify a frequency range. The UE may determine whether to measure the reference signal based on whether the reference signal is within the identified frequency range. The UE may refrain from measuring the reference signal in response to the determination. The UE may also refrain from measuring the reference signal in response to a SIB received at the UE not including a ULI, or in response to a frequency associated with the reference signal not being in a list of supported bands for EN-DC. As a result, inter-RAT handovers from LTE base stations to 5G base stations are prevented, UE power consumption is thereby saved, and support for EN-DC is maintained.

Abstract: Methods, systems, and devices for wireless communications are described. A system may support techniques for triggering user equipment (UE) assistance information (UAI) based on mobility, wake up signal (WUS) configuration, or both. In some cases, a UE may communicate with a network node (e.g., a base station) on a first channel according to a discontinuous reception (DRX) configuration. The UE may determine that a speed of the UE satisfies a mobility threshold and may transmit UAI requesting one or more updated DRX configuration parameters based on the speed of the UE satisfying the mobility threshold. Additionally or alternatively, the UE may receive signaling configuring the UE to monitor for WUSs and may transmit UAI requesting one or more updated DRX configuration parameters based on the WUS configuration. The UE may receive control signaling configuring the DRX configuration with the one or more requested parameters in response to the UAI.

Abstract: A method of wireless communication, by a user equipment (UE), includes setting up a secondary cell group (SCG) with a second radio access technology (RAT) that differs from a first RAT associated with a master cell group (MCG). The method also includes communicating wirelessly via the secondary cell group and the master cell group. The method further includes predicting a radio link failure (RLF) for the secondary cell group based on multiple inputs to a machine learning model. The method still further includes routing data transmission from the secondary cell group to the master cell group, after predicting the SCG RLF.

Abstract: The present disclosure relates to a user equipment (UE) dynamically adjusting a non-access stratum (NAS) timer. Specifically, the UE may determine operation in a wideband and support of an extended coverage (EC) restriction. The UE may further identify a duration of a non-access stratum (NAS) timer based on determining operation in the wideband and the EC restriction. The UE may further transmit an access request message to a network entity to trigger a mobility management procedure. The UE may further receive an acceptance message from the network entity indicating an unrestricted or restricted status of the EC restriction. The UE may further apply the duration to the NAS timer based on the acceptance message indicating the unrestricted or restricted status of the EC restriction received from the network entity or a history of EC restrictions of a public land mobile network (PLMN) in a defined geographic area.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a robust measurement procedure for neighbor base stations (BSs) that are handoff candidates. In some aspects, a user equipment (UE) may designate a first 5G New Radio (NR) neighbor BS as a handoff candidate for the UE based on a first signal strength measurement. The UE may configure a measurement time interval to perform one or more additional signal strength measurements prior to expiration of a time to trigger (TTT) time period. The UE may determine the measurement time interval based on a duration of the TTT time period configured by a serving BS and a number of additional signal strength measurements. The UE may transmit a measurement report to the serving BS after performing the last signal strength measurement and prior to expiration of the TTT time period.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling for communications in a wireless communications system. The control signaling may indicate a first duration for an inactivity timer. The UE may initiate the inactivity timer and a second timer based on identifying a period of inactivity. The second timer may have a second duration that is shorter than the first duration for the inactivity timer. In some examples, the second duration may be based on one or more parameters, such as a display status, a battery status, a scaling factor, the first duration, an application state, or any combination thereof. The UE may release a connection for the communications in the wireless communications system based on an expiration of the second timer, an expiration of the inactivity timer, or a combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a first call associated with a first subscriber of the UE. The UE may establish a second call associated with a second subscriber of the UE, wherein the first subscriber and the second subscriber are active contemporaneously, and wherein the first call and the second call are associated with a first radio access technology (RAT). The UE may identify a mobility event that associated with an interruption to at least one of the first call and the second call, the mobility event involving switching the first subscriber to a second RAT. The UE may perform a mitigation action. Numerous other aspects are described.
