  • Publication number: 20240073747
    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.

  • Publication number: 20230422130
    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.

  • Publication number: 20230269821
    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.

  • Publication number: 20230247461
    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.

  • Publication number: 20230232265
    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.

  • Publication number: 20230180072
    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.

  • Patent number: 11510209
    Abstract: 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.

  • Patent number: 11363445
    Abstract: 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.
