摘要： 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.

摘要： 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

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： An overall architecture to integrate multicast and broadcast service into a general 5G core network. The architecture may provide methods and systems to switch the delivery mode of transmitting messages to User Equipment (UE)s from a unicast mode to a multicast mode. The method includes triggering events at UE, network functions, content provider or RAN node to initiate the switch process; a procedure for UE initiated switch from unicast to multicast; a procedure for network-initiated switch from unicast mode to multicast mode; and a procedure for RAN initiated switch from unicast mode to multicast mode. The architecture may also provide methods to switch the delivery mode from multicast mode to unicast mode. These methods may include triggering events at UE, network functions, content provider or RAN node to initiate the switch process; a procedure for UE initiated switch from multicast mode to unicast mode; a procedure for network-initiated switch from multicast mode to unicast mode; and a procedure for RAN initiated switch from multicast mode to unicast mode.

摘要： User equipment (UE) may detect a disaster condition, and the resolution thereof, based on broadcast information, RRC messaging, NAS messaging, the ability to connect to an allowable PLMN, and indications from forbidden PLMNs. In a disaster condition, a UE may perform an enhanced PLMN selection procedure wherein, for example, the UE will not consider PLMNs that are in a disaster situation if the disaster situation applies to a current location of the UE, prioritize forbidden PLMNs for disaster roaming connection. For disaster roaming connection, the UE may be configured by an otherwise forbidden PLMN with information about what services the UE can access and what type of authentication procedure the network is able to perform with UE. Upon detecting that the disaster condition is over, the UE move back to an allowable PLMN.
