Abstract: Methods, apparatus, and systems are described for assistance information from the UE to network side, e.g., enabling faster decision-making for secondary cell group deactivation in 3GPP MR DC/CA deployments. According to some aspects, instructions for UE behavior upon MR DC/CA secondary cell group activation are provided in a secondary cell group deactivation message to reduce delays for a UE triggered secondary group activation. RRC signaling ambiguities for conditional PSCell addition/change may be resolved by a synchronization message between a main node and a secondary node to avoid delays and signaling errors.

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.

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.

Sidelink configuration may include indications of signals and/or channels for use in sidelink transmit and/or receive communications, etc.

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).

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.

Disclosed herein are various problems and enhancements related to UL RS based DL BM, in particular beam failure detection and recovery.
