  • Publication number: 20240129904
    Abstract: Techniques for wireless communication at a communication device are described. The communication device may be a user equipment (UE) configured to transmit, to a base station, signaling indicating UE capability information. The UE may receive, from the base station, control signaling indicating a measurement gap sequence configuration based on the UE capability information. The UE may determine a measurement gap occasion based on the measurement gap sequence configuration. The measurement gap occasion may include one or more of a first measurement gap occasion associated with a first measurement gap sequence, a second measurement gap occasion associated with a second measurement gap sequence, or a combination of the first measurement gap occasion and the second measurement gap occasion. The UE may perform a set of channel measurements during the determined measurement gap occasion.

  • Publication number: 20230180177
    Abstract: A mobile device can report its capabilities to a network node regarding one or more phase characteristics between Sounding Resource Signal (SRS) resources transmitted by the mobile device under one or more circumstances, enabling the network to configure the mobile device accordingly. Such reporting can enable the network to coherently process multiple SRS resources, effectively increasing the bandwidth of the SRS resources and, ultimately, the accuracy of a position determination for the mobile device. Various techniques are provided for reporting capabilities and determining applicable conditions.

  • Publication number: 20230127705
    Abstract: A multi-SIM user equipment (UE) can perform link failure operations associated with a first universal subscriber identity module (USIM) in an active state during a time gap when the UE can perform a network operation on a second USIM in a non-active state. The UE can monitor a failure event associated with the first USIM using a first procedure. The failure event includes a radio link failure, a beam failure, and/or a listen-before-talk (LBT) failure. The UE can transmit a request to a network entity for a time gap to perform a network operation associated with the second USIM, while the first USIM remains in a radio resource control (RRC) connected state during the time gap. The UE can monitor, using a second procedure during the time gap, the failure event associated with the first USIM.

  • Patent number: 11363536
    Abstract: This disclosure provides systems, methods and apparatuses for user equipment (UE)-side and network-side mitigation of intermodulation (IM) interference, such as IM interference associated with multi-radio access technology communications. For example, the UE or a base station may detect an IM interference condition, and may perform an IM mitigation action based on detecting the IM interference condition. The UE may reduce an uplink transmit power so that IM interference on the downlink is reduced. Various base station IM mitigation actions are provided, such as suspending scheduling on a bearer, using a scheduling pattern that avoids concurrent transmission, reducing a maximum transmit power of an uplink grant of the UE, allocating resource blocks or bandwidth parts that do not overlap with an IM interference resource, changing a secondary cell group channel to a non-interfering channel, releasing a secondary cell group channel, deactivating a carrier, or changing a channel of the UE.
