Abstract: A user equipment (UE) may operate on a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier. The UE identifies a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier corresponding to a primary secondary cell (PSCell) of a secondary cell group (SCG) for dual connectivity (DC), receives an indication that an active BWP is to be switched from the non-dormant BWP to the dormant BWP and performs an action corresponding to the dormant BWP.

Abstract: A user equipment (UE), next generation NodeB (gNB), or other network component can operate to configure a group configuration message that initiates a plurality of UEs in a coverage area of a non-terrestrial network (NTN) to concurrently transfer communication from a first beam of a first satellite to a second beam of a second satellite. The communications of one or more UEs can be re-directed to the second beam of the second satellite based on downlink control information of the group configuration message.

Abstract: Techniques for physical uplink control channel (PUCCH) operation with multiple transmission and reception point (multi-TRP) are disclosed. In some embodiments, determining PUCCH transmission repetition may include determining that an original PUCCH transmission overlaps a slot boundary between a first slot for PUCCH transmission and a second slot for PUCCH transmission, and configuring a PUCCH repetition of the original PUCCH transmission. The PUCCH repetition may include one or more symbols of the original PUCCH transmission and may be located in one or more slots other than the first slot and the second slot. The PUCCH repetition may be configured by a downlink control information (DCI) configuration that includes a physical downlink shared channel to hybrid automatic repeat request acknowledgement feedback (PDSCH-to-HARQ_feedback) timing indicator, a PUCCH repetition number field that configures a number of transmissions of the PUCCH repetition, or a PUCCH resource indicator field that configures a number of transmissions of the PUCCH repetition.

Abstract: A user equipment (UE) device may perform random access to a base station in the context where propagation delay between the base station and the UE device is large. The UE device randomly selects a random access preamble from an available set of preambles. The UE device selects a time slot for transmission of the random access preamble based on a configured correspondence between allowable time slots and subsets of the available set. The UE device transmits the random access preamble to a base station in the selected time slot, with timing advance to compensate for a common delay. Thus, the base station, knowing the configured correspondence, is able to determine the time slot in which the random access preamble was transmitted. The UE device receives a random access response that has been addressed with a Random Access Radio Network Temporary Identifier (RA-RNTI).

Abstract: A user equipment (UE) is configured to deactivate/activate a point-to-multipoint (PTM) link of a multicast radio bearer (MRB). The UE receives, from a base station of a wireless network, a multicast radio bearer (MRB) configuration, wherein the MRB includes configuration of a split MRB including a point to multipoint (PTM) link and a point to point (PTP) link, deactivates or activates the PTM link based on the MRB configuration, reestablishes a radio link control (RLC) associated with the PTM link and recovers a packet data convergence protocol (PDCP).

Abstract: The present application relates to devices and components including apparatus, systems, and methods for L2 resets. For example, a UE can be connected to a base station DU via a first cell and can be configured with information about a second cell. This information can indicate whether an LTM association exists between the first cell and the second cell (e.g., whether these two cells are provided by the same base station DU or not). Upon a command to establish a connection with the second cell (e.g., a MAC CE handover command), the UE can determine whether an L2 reset is to be performed or not based on the configuration information (e.g., the L2 reset can be foregone when the two cells are provided by the same base station DU; otherwise, the L2 reset can be performed).

Abstract: Systems and methods are disclosed herein for using integrated access and backhaul (IAB) nodes configured to provide multi-access edge computing (MEC) functionality. An IAB node may include a MEC functionality that includes an instance of an application configured for MEC. A UE using the application connects to the network through an access link with the IAB node and establishes a PDU session for traffic of the application with a core network (CN). The CN may determine that the traffic corresponds to the application, and that an instance of the application is present on the IAB node. Accordingly, the CN may instruct the IAB donor to instantiate a remote packet data convergence protocol (PDCP) layer and, in some cases, a remote service data application (SDAP) layer that are configured to route the traffic from the UE for the application to the instance of the application on the IAB node.

Abstract: A user equipment (UE) configured to monitor paging occasions of a network. The UE operates in a paging discontinuous reception (DRX) cycle, wherein the DRX cycle includes a paging occasion (PO). The UE determines a location in time for a wake-up signal (WUS) occasion associated with the PO and determines whether to utilize an active mode or a sleep mode during the PO based on an indication included in a WUS received during the WUS occasion.

Abstract: An approach is described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a second UE and a wireless device and a processor communicatively coupled to the transceiver. The processor is configured receive, from the second UE, an end-to-end (E2E) quality of service (QoS) requirement of an E2E connection between the second UE and the wireless device, wherein the E2E connection includes a first hop between the UE and the second UE and a second hop between the UE and the wireless device. The processor is further configured to obtain a first hop link condition and a second hop link condition; split the E2E QoS requirement into a first hop QoS requirement and a second hop QoS requirement based on the first hop link condition and the second hop link condition; and transmit, using the transceiver, the first hop QoS requirement to the second UE. The wireless device is a third UE or a base station.
