    Abstract: Systems and methods for performing timing advance (TA) validation at a user equipment (UE) for a TA to be used when transmitting a configured grant small data transmission (CG-SDT). Mechanisms for bounding one or more measurement windows during which one or more synchronization signal blocks are measured during a reference signal received power (RSRP) measurement method of the TA validation are discussed, and may be set using information corresponding to timing drift due to relativistic effects, clock differences between a UE and a base station, and/or information about a UE discontinuous reception (DRX) cycle. Further, time interval limitations between various events attendant to such an RSRP measurement method are discussed as being determined using information corresponding to timing drift due to relativistic effects, clock differences between a UE and a base station, information about a DRX cycle used at the UE, and/or a maximum TA timer duration.

    Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, informing and/or requesting the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

    Abstract: The exemplary embodiments relate to a user equipment (UE) delivering an indication of one or more uplink listen-before-talk (LBT) failures to a network. The UE may identify a predetermined condition corresponding to one or more uplink listen-before-talk (LBT) failures associated with a special cell (SpCell). The UE is triggered to provide an indication of uplink LBT failure associated with the SpCell to the network based on the predetermined condition. Next, the UE may determine a type of message that is to be used to deliver the indication of uplink LBT failure associated with the SpCell to the network. The UE may transmit the type of message including the indication of uplink LBT failure associated with the SpCell to the network. Subsequently, the UE may determine that the network received the indication of uplink LBT failure associated with the SpCell.

    Abstract: Techniques described herein may include a special scheduling cell (sSCell) provided for dynamic spectrum sharing (DSS). The sSCell may schedule a primary cell of a master cell group (MCG) or a primary cell of a secondary cell group (SCG). The primary cell may be referred to as a special cell or SpCell. The sSCell may be activated and/or deactivated, enter in or exit from a state of dormancy, and radio link monitoring (RLM), beam failure recovery (BFR), and cell grouping parameters may be provided. Techniques described herein include configuring a UE-specific search space (USS) with non-fallback downlink control information (DCI), USS with fallback DCI, and overall search space for DSS enhancement.

    Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to use multiple carriers selected from a set of available carriers that can be associated with different TAGs. When a second set of carriers, used after switching from a first set of carriers, includes carriers that belong to different TAGs, the wireless device determines whether to transmit on one or more first uplink transmission occasions for each of the carriers in the second set of carriers based on whether a first UL transmission occasion for at least one carrier overlaps a switching gap time period. The wireless device can disallow transmission on first UL transmission occasions of one or more carriers to accommodate the overlap.
