Abstract: Beam management for the downlink can be based on user equipment (UE) measurement of downlink (DL) reference signal (RS) and UE reporting. An alternative approach that may reduce overall RS overhead and latency is BM for the downlink based on uplink (UL) RS. With this approach, the network measures UL RS transmissions on multiple beams and uses these measurements for managing beams for the DL. Disclosed herein are various problems and enhancements related to UL RS based DL BM, in particular beam failure detection and recovery.

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.

The remote UE may detect and reselect to a cell via a Relay UE while it has selected a serving cell via the Uu interface.

Abstract: Wireless User Equipment, UE, and network apparatuses may be adapted to facilitate continuity of Multicast/Broadcast Service, MBS, across cells. A UE in idle/inactive mode, for example, may receive MBS assistance information comprising scheduling information defining MB S reception windows and perform a cell re selection evaluation process accordingly. An UE in connected mode may conduct and report MB S quality measurements and receive an RRC reconfiguration comprising an MB S configuration for a target cell, determine that MBS transmission progress differs between the source cell and the target cell, and recover lost MBS PDUs or delete duplicate MBS PDUs accordingly. A network apparatus, such as a gNB for example, may map a GPRS Tunneling Protocol Sequence Number of an MBS PDU, to a Packet Data Convergence Protocol Sequence Number in a target cell, and determine an MB S configuration for use by a UE requesting a handover accordingly.

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 WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beam in the beam group.
