Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.

Abstract: Methods and systems are disclosed for a UE of a wireless communication network to recover from MCG radio link failures in a MR-DC system when the SCG is deactivated or otherwise not enabled. When a MCG link failure is detected and the SCG is deactivated, the UE may activate the SCG for the UE to use the SCG link to transmit and receive signaling messages or data as part of the MCG failure recovery procedure. When the MCG link failure is detected and the UE is configured to add the SCG upon the satisfaction of certain condition, but the condition has not occurred, the UE may check to determine whether one condition is MCG failure and whether the radio link quality of the SCG exceeds a threshold. If the radio link quality of the SCG exceeds the threshold, the UE may apply the SCG configuration to add the SCG.

Abstract: A base station is configured to transmit wake-up signals to a user equipment to wake-up the UE to receive a page from the base station. The base station transmits one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to a user equipment (UE) operating in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO) and transmits the WUS to the UE during a WUS occasion, wherein the WUS indicates whether the UE is to utilize an active mode or a sleep mode during the PO.

Abstract: The present application relates to devices and components including apparatus, systems, and methods for partial sensing for resource selection, reevaluation, and preemption. In some embodiments: a UE receives configuration information for a resource pool; determines a type of traffic to be transmitted by the UE, the type to include aperiodic traffic or periodic traffic; determines, based on the configuration information and traffic type, first and second values to define a window for contiguous partial sensing; and performs contiguous partial sensing within the window.

Abstract: Techniques are disclosed for the harmonization of a spectrum access tier and a core network architecture. One example includes a method implemented for the harmonization of a spectrum access tier and a core network architecture. An access and mobility management function (AMF) of a first network can receive a first request message, including a spectrum inquiry request from a base station to an automated frequency coordinator of the first network. The automated frequency coordinator can use an AMF interface and an automated frequency coordinator interface to determine a spectrum inquiry response. The spectrum inquiry response can describe an available frequency band of a spectrum access tier of a second network for the base station. The AMF can transmit the spectrum inquiry response to the base station.

Abstract: A base station (BS) may receive, from a network node, one or more data packets including one or more reflective quality of service (QoS) indicator (RQI) markings. The base station may then determine, based on a value of the one or more RQI markings, one or more active uplink (UL) QoS rules associated with a user equipment (UE). The base station may further determine, based on at least one of one or more timers, the one or more active UL QoS rules, and status information received from the UE, to include or refrain from including the one or more RQI markings in a transmission of the one or more data packets to the UE. Accordingly, in response to the determining that the RQI markings should be included, the base station may then transmit the one or more packets including the RQI markings to the UE.

Abstract: Apparatuses, systems, and methods for performing uplink transmissions during a dual active protocol stack handover. A wireless device may determine a propagation delay between the wireless device and each of a source cell and a target cell of a dual active protocol stack handover by the wireless device. The wireless device may provide an indication to the source cell of the propagation delay between the wireless device and the source cell, the propagation delay between the wireless device and the target cell, and a propagation delay difference handling capability of the wireless device. The cellular base station that provides the source cell may determine a time division multiplexing pattern for uplink communication for the wireless device during the dual active protocol stack handover based at least in part on the information provided by the wireless device.
