Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station associated with a first radio access technology (RAT), an indication to add a secondary cell associated with a second RAT in a dual connectivity mode. The UE may receive, by a lower layer of the UE from the secondary cell, an indication that a random access channel (RACH) procedure associated with the secondary cell is successful. The UE may transmit, by an upper layer of the UE to an application of the UE, information to cause an indication of the second RAT to be displayed by the UE based at least in part on a bearer type associated with a link with the secondary cell and the indication that the RACH procedure with the secondary cell is successful. Numerous other aspects are provided.

Abstract: In some implementations, a user equipment (UE) may detect a trigger to provide a measurement report associated with a redirection from a first radio access technology (RAT) to a second RAT. The trigger may be a reference signal metric associated with the second RAT satisfying a threshold associated with the reference signal metric. The threshold may be configured by abase station. The UE may selectively provide the measurement report based at least in part on whether one or more other reference signal metrics satisfy one or more other thresholds corresponding to the one or more other reference signal metrics. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may support one or more applications enabling various types of users to access relevant information relating to performance of the UE across one or more communication modes or radio access technologies (RATs). A type or granularity of the information that the UE provides to the user may depend on a type of the user. For example, if the UE detects that a user is a first user type, the UE may provide the user with relatively simpler or more basic information relating to UE performance. Alternatively, if the UE detects that a user is a second user type, the UE may provide the user with relatively more technical or granular information relating to UE performance. The UE may support a user interface via which the UE may present the information to a user.

Abstract: A method of wireless communication performed by a user equipment (UE) includes in the UE, having a first subscriber identity module (SIM) and a second SIM, causing the first SIM to camp on a first cell associated with a first technology in standalone mode; selecting a second cell associated with a second technology in standalone mode; and causing the second SIM to camp on the second cell concurrently with the first SLM camping on the first cell.

Abstract: Aspects described herein relate to receiving, for a first cell, a broadcast signal including an indication that the first cell supports reduced capability UE, and prioritizing, based on the indication, conditional handover or conditional cell change from a serving cell to the first cell over handover or redirection from the serving cell to a second cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a measurement gap configuration from a base station, wherein the measurement gap configuration includes a tune away period. The UE may determine whether one or more data traffic criteria are satisfied for the tune away period. The UE may disregard the measurement gap configuration based at least in part on the determination of whether the one or more data traffic criteria are satisfied. The UE may remain tuned to the base station during the tune away period based at least in part on the determination of whether the one or more data traffic criteria are satisfied. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to mechanisms for enhancement in UE cell selection to prioritize cells supporting 5G New Radio (NR) in standalone mode (SA) and in non-standalone (NSA) mode. In some examples, a UE may identify a plurality of cells within an area including a location of the UE. Each cell supports at least one radio access technology (RAT) and at least one frequency. The UE may determine a selection order of the plurality of cells based on the supported RATs and frequency bands to prioritize cells supporting the latest RAT (e.g., 5G NR) and select a serving cell based on the selection order.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a ping-pong event between a non-standalone (NSA) New Radio (NR) network and a standalone (SA) legacy network. The UE may transmit, to the SA legacy network, an indication of radio link failure with the NSA NR network, based at least in part on the ping-pong event and one or more indicators of channel quality with the NSA NR network. The UE may measure, periodically, one or more reference signals from the NSA NR network. The UE may reconnect to the NSA NR network based at least in part on the one or more reference signals satisfying at least one condition. Numerous other aspects are provided.

Abstract: Aspects presented herein may improve a UE's performance by optimizing the CDRX toggling at the UE. In one aspect, a UE transmits, to a base station, a first UE assistance information request, where the first UE assistance information request include s at least one of an updated CDRX cycle or an updated inactivity timer period, and the updated CDRX cycle is different from an initial CDRX cycle and/or the updated inactivity timer period is different from an initial inactivity timer period. The UE adjusts the initial CDRX cycle to the updated CDRX cycle based on the first UE assistance information request. The UE transmits, to the base station after the initial CDRX cycle is adjusted, a second UE assistance information request, where the second UE assistance information request includes at least one of the initial CDRX cycle or the initial inactivity timer period.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may configure a user equipment (UE) with a time to trigger (TTT) and a signal quality threshold. The UE may determine whether one or more conditions are satisfied, and if so, transmit an early measurement report or ignore a conflicting procedure that renders the measurements unavailable. In some examples, a UE may receive an indication of a minimum TTT in a configuration message with the TTT and the signal quality threshold. The UE may indicate an updated timing, to a base station, based on the minimum TTT. In some examples, the base station may determine that a UE is a multi-subscriber identification module (MSIM) UE, and may configure the duration of the TTT accordingly.
