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.

Measurement reporting timing adjustments

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.

UE enhancement prioritizing 5G NR cell selection

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.

User equipment optimization for connected mode discontinuous reception toggling

In one aspect, a method of wireless communication includes obtaining, by a user equipment (UE), measurement information for a current beam and one or more surrounding beams. The method also includes generating, by the UE, surrounding beam information based on the measurement information. The method further includes outputting, by the UE, an indication of the surrounding beam information. Other aspects and features are also claimed and described.

Systems and methods for surrounding beam information indication

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 SIM camping on the first cell.

Opportunistic dual SIM dual active operation in multi-subscriber identity module devices

Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may determine that its operating temperature exceeds an overheating condition threshold temperature, reducing overall device performance. To address the overheating condition, the UE may transmit an uplink control message containing UE assistance information to request a reconfiguration of one or more measurement parameters. In some cases, the UE may request to reduce one or more measurements associated with radio resource management (RRM). The UE may receive a downlink control message from a base station which indicates a reconfiguration of the measurement parameters, and the UE may implement the reconfiguration to mitigate the overheating.

Overheating triggered radio resource management (RRM) relaxation

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.

Random access channel procedure based radio access technology display indication

Wireless communication techniques that include network service discovery and selection techniques in wireless communication systems are discussed. A UE may trigger a first subscription concealed identifier (SUCI) calculation associated with a first registration procedure. The first registration procedure may be used to register the UE in a first wireless communication network associated with a first radio access technology (RAT). The UE may also trigger a second registration procedure to register the UE in a second wireless communication network associated with a second RAT upon detecting a first failure instance of the first SUCI calculation. Other features are also described.

UE optimization to move between wireless communication networks based on SUCI support

Methods, systems, and devices for recovery techniques for subscriber identification module (SIM) detection error are described. A user equipment (UE) may determine an operating mode for the UE based on a SIM card switch occasion. The SIM card switch occasion may be a 'hotswap' occasion of a SIM card while the UE is powered on. The UE may power a SIM card associated with the UE based on the operating mode for the UE and a previous status of a SIM slot associated with the UE. The UE may detect a presence of the SIM card in the SIM slot based on powering the SIM card. The UE may set a SIM sensing operation at the UE based on the detected presence of the SIM card.
