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: A first apparatus receives, from a second apparatus via a sidelink (SL) transmission, first configuration parameters for a first SL DRX group and second configuration parameters for a second SL DRX group. The first configuration parameters for the first SL DRX group comprise: a common SL DRX parameter set that is shared with the second configuration parameters for the second SL DRX group, and a first dedicated SL DRX configuration parameter set. The first dedicated DRX parameter set comprises: a first on duration at the beginning of a SL DRX cycle of the first apparatus, and a first duration: after an occasion of a PSCCH carrying a first-stage SL control information (SCI) indicates a new SL transmission for a MAC entity of the first apparatus, or after an occasion of a PSSCH carrying a second-stage SCI indicates a new SL transmission for the MAC entity of the first apparatus. The first apparatus determines that the first apparatus is in a first SL active time for receiving information on the SL based on the first configuration parameters for the first SL DRX group, and in a second SL active time for receiving information on the SL based on the configuration parameter for the second SL DRX group.

Abstract: The performance of user equipment (UE) using sidelink radio communications may be improved by providing the UE with sidelink configuration information pertaining to modes, functions, channels, signals, and/or resources for use in sidelink communications. For example, a UE may receive information indicating a sidelink mode, e.g., a transmit-only, receive-only, or a transmit and receive mode. Sidelink configuration may include indications of signals and/or channels for use in sidelink transmit and/or receive communications, etc.

Abstract: Methods, apparatus, and systems for beam management and BWP operations for NR NTN. Beam management methods for both one beam per cell and for multiple beams per cell may be implemented. A transmission configuration indication (TCI) state sequence also may be implemented, in which a network node may broadcast the transmission of TCI states.

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.

Abstract: User equipment in radio networks may be adapted to dynamically select connections to terrestrial and non-terrestrial cells in accordance with detected and/or signaled network properties, and adjust communication expectations for return trip times in accordance with timing and conditions encountered with non-terrestrial equipment, including non-geosynchronous high-altitude and/or low earth orbit equipment, and/or other equipment which is in motion relative to the earth and/or the user equipment. The types of equipment used in a cell, and/or ephemeris associated therewith, may be signaled by the network and/or determined by the user equipment via analysis of synchronization signals, for example.

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: 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, 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.
