Abstract: Methods for dynamic user plane management may include new Layer 2 architectures for supporting simultaneous User Plane direct and indirect connections between a remote UE and gNB. Methods are described for dynamically managing UP Plane connections based on the QoS requirement of the traffic flow and the power consumption requirement of the remote UE. A method is described for dynamically managing CP connections between a remote UE and remote UE via a direct CP connection. A method is described for dynamically managing CP connections between a remote UE and remote UE via an indirect CP connection.

Abstract: Methods and apparatuses are described herein for Multi cast/Broadcast Services (MBS). The embodiments described herein are directed to procedures for managing multiplexed MBS traffic, for prioritization between MBS related UL traffic, unicast UL traffic, and SL traffic, for handling HARQ retransmissions over C-RNTI, to support PDCP Status Reporting for MBS services, and for a wireless transmit/receive unit (WTRU) joining already started/activated Multicast Sessions. In one example, a WTRU may receive multiplexed MBS services via one or more MBS radio bearers (MRB) and/or one or more unicast data radio bearers (DRBs). The WTRU may be configured with a single Service Data Adaptation Protocol (SDAP) entity for the MBS services, and demultiplexing of traffic may be performed at the SDAP layer. The WTRU may be configured to demultiplex multiple logical channels across different MBS services, where the logical channels are received over the same transport block.

Abstract: Multicast/Broadcast Service (MBS) for user equipments (UE) in Radio Resource Control (RRC) idle/inactive modes via signally of MBS frequency ranges and/or switching between frequency ranges as required. Bandwidth Part (BWP) operation for MBS in RRC IDLE and RRC INACTIVE states may be implemented using a dedicated MBS BWP or by sharing a frequency range with other operations. An MBS frequency range may be wider or narrower than an initial BWP used by a UE, for example. MBS frequency range configure may be achieved in a number of ways, such as via Control Resource Set (CORESET), search space, and/or PDCCH monitoring occasions pattern settings for MBS in RRC idle/inactive. Downlink scheduling without dynamic grant for MBS in RRC idle/inactive may include configured scheduling and/or semi-persistent scheduling. Downlink repetition for MBS in RRC idle/inactive may include PDSCH repetition and/or PDCCH repetition

Abstract: Methods and apparatuses are described herein for 5G MBS operation. The proposed method and procedures overcome the limitations that have been observed in LTE and UTRAN MBMS operation, address the unique characteristic of 5G NR, and meet the requirements set out by the envisioned 5G MBS use cases by providing functions including RAN xcasting area concepts that are flexible and dynamic, MBS radio bearer (MRB) types to support MBS services, RAN architectures to support the various MBS radio bearer types, as well as functionality split across the RAN nodes to support these radio bearers, procedures to allow radio bearer selection, monitoring, and switching, and procedures to allow xcast area management.

Abstract: Methods, systems, and apparatuses may assist scheduling for broadcast and groupcast on new radio Uu interface. In an example, there may be broadcast and groupcast transmission scheduling mechanism with: group based scheduling, UE specific based scheduling, or sub-group based scheduling. In another example, there may be a serving cell configuration for broadcast and groupcast transmission with dedicated cell for broadcast and groupcast, or broadcast and groupcast cell which is shared with the cell for unicast. In another example, there may be downlink control related configuration for broadcast and groupcast transmission with details of the BWP configuration, the CORESET configuration, or the search space configuration.

Abstract: A radio apparatus communicating with a first and a second network, and having a first connection to the first network, may receive a page from the second network and determine to form a second connection with the second network, and notify the first network of the selection. The first network may then notify the apparatus to release or suspend the first connection. The apparatus may send release and/or suspension preferences to the first network, such as a preference to be treated in an idle or inactive mode, paging preferences, and a preferred identifier of the apparatus. The apparatus may then form the second connection, and monitor for paging from the first network, e.g., during a given paging occasion and paging frame.

Abstract: The present application describes methods and systems for cell selection and reselection. One aspect describes the apparatus including a non-transitory memory including executable instructions for cell selection or cell reselection, which when executed by a processor, performs the instructions of determining one or more new public land mobile networks (PLMNs) have been selected. The processor is also configured to execute the instructions of scanning radio frequencies for one or more cells in one or more of the selected PLMNs. The processor is further configured to execute the instructions of determining the one or more cells to be an acceptable cell, a suitable cell, not an acceptable cell, or not a suitable cell. The processor is even further configured to execute the instructions of determining a state of the apparatus to be a multi-camped normally state, a reduced power any cell selection state, a reduced power camped on any cell, a camped normally state, an any cell selection state, or a camped on any cell state.

Abstract: A user equipment (UE) operating in an “Onboarding Mode” may search for a network broadcasting Onboarding Capability Information (OCT), then register using onboarding credentials and receive SNPN credentials from the network. The UE may then exit onboarding mode, enter Manual Network Selection or Automatic Network Selection mode, and connect to the SNPN. A UE may also receive from a network a list of PLMNs and SNPNs that are equivalent then, when registering, indicate to the network that a requested slice is not associated with the IJE's HPLMN, but is associated with an SNPN. The network may indicate to the UE how the slices of the network map to the slices of the SNPN, and may indicate whether a slice that is offered by the network only partially maps to a slice of the SNPN or HPLMN.

Abstract: Methods, apparatus, and systems are described for new radio (NR) sidelink resource allocation, e.g., for power saving and bandwidth part (BWP) operations. According to some aspects, different types of resource sets and signaling (e.g., preferred, non-preferred, resource conflict, etc.) may be considered and it may be indicated to user equipment (UE) which type of resources should be used based on certain criteria, e.g., least power consumption criteria.

Abstract: Radio network Positioning Reference Signals (PRSs) may be managed dynamically via user equipment (UE) requests triggered by measurements in accordance with initial PRS configurations, whereby a UE contacts an Access and Mobility Management Function (AMF) and/or a Location Management Function (LMF). Similarly, an LMF may initiate adjustments in PRS configurations and transmission via communications with base stations, UEs, and/or AMFs. Dynamic signaling of PRS configurations may be achieved via legacy protocols and/or New Radio Positioning Protocol A (NRPPa), for example. A requests from a UE for PRS configuration adjustment may include an indication of a required level of service or of a class of service, for example, and/or an indication of signal measurements, a position estimate, an indication of a capability of the UE.
