    Abstract: Methods and apparatuses are described herein for Multi cast/B roadcast 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: Methods are described for enabling 5G MBS operation. The disclosed methods overcome limitations in LTE and UTRAN MBMS operation, address the unique characteristic of 5G NR, and meet requirements of 5G MBS use cases. Disclosed are techniques for MCCH configuration procedures, including change notification procedures; triggers for MCCH acquisition; a RAN paging procedure for triggering counting for UEs in RRC INACTIVE; triggers for an MBS interest indication based on BWP switching; a timescale for scheduling of an MRB transport channel, a signal control channel, and a traffic channel; procedures for scheduling MCCH, including a scheduling configuration, an SCS, and a BWP; procedures for scheduling (P)TrCH; and procedures for scheduling MTCH.

    Abstract: Synchronization Signal Block (SSB) management for new radio may be achieved through indication of a maximum number of beams for beamforming and/or through mechanisms for handling plural candidate SSBs. For example, a User Equipment (UE) may search a Primary Synchronization Signal (PSS) and/or a Secondary Synchronization Signal (SSS) to decode a Physical Broadcast Channel (PBCH) payload comprising and indication of a maximum number of beams (Q) supporting beamforming, e.g., in new radio unlicensed spectrum, and determine, based the indicator, Quasi Co-Located (QCL) Synchronization Signal Blocks (SSBs). Similarly, a UE may determine, from the PBCH payload, a primary DeModulation Reference Signal (DMRS) from which the UE may determine selection bits for an SSB. The UE may also determine, based a frequency range in use, to perform a secondary detection and based on the secondary detection, alter selection bits for accessing the SSB index.

    Abstract: A wireless device, such as user equipment (UE) or other apparatus, like may use a transparent mode operation in which the device is not aware of the operation mode of a base station, such as a gNB or other transmission and receive point (TRP), via the use of configurations for Frame Based Equipment (FBE) and Load Based Equipment (LBE) operating modes. A base station may initiate a Channel Occupancy Time (COT) that is an FBE COT or an LBE COT, in which the wireless device follows FBE or LBE procedures accordingly. A variety of criteria may be applied in determining whether to use FBE or LBE procedures, and to switch between them. A network may use indicate the intention to switch operation mode and may do so via implicit or explicit indications. Similarly, a wireless device may autonomously switch operation mode, and may indicate the selected mode to the network.

    Abstract: UEs' mobility may have a significant impact on sidelink communications and Uu mobility procedures of UEs participating in SL communication or SL Group Communication. Methods devised to optimize handover procedures, cell reselection procedures, and transition to RRC_IDLE and RRC_INACTIVE for UEs with ongoing SL communications. Methods are disclosed herein for PLMN selection for UEs requiring sidelink communication or with active sidelink communication, as well as, methods to provide priority-based resource allocation while using exceptional transmit resource pools. Also, provided are SL group management procedures to deal with impacts of UE mobility.

    Abstract: A Sidelink AS group management function is disclosed for a UE to discover group members and organize them into AS layer sub-groups based on the AS layer group context information. A centralized Sidelink AS group management is disclosed that the Sidelink AS Group Manager discovers group members and organizes them into AS layer sub-groups for a UE. A Subgroup formation and configuration procedure is disclosed that SL AS Group Manager organizes the ULG into AS layer sub-groups, configures UE-to-UE relays for each UE in the ULG and sends the AS group management information to the UE. A distributed Sidelink AS group management method is disclosed that each UE discovers its group members and organizes the ULG into AS layer sub-groups. New Layer 2 structures and procedures are disclosed to enhance bearer management for Sidelink groupcast communications.
