Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products directed to channel access with channel occupancy time (COT) sharing are described herein. A method implemented in a wireless transmit/receive unit (WTRU) includes transmitting, to a base station, first scheduling information associated with a SL transmission to be transmitted to another WTRU in unlicensed spectrum. The method includes receiving, from the base station, second scheduling information indicating a scheduling of the SL transmission and a shared COT, wherein the shared COT may be shared between any of uplink, downlink and sidelink transmissions. The method includes determining that the SL transmission is scheduled in the shared COT. The method includes transmitting the SL transmission to the other WTRU with no listen before talk (LBT) or with a shorter LBT than a full LBT based on the determining that the SL transmission may be scheduled in the shared channel occupancy time.

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.

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.

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: A user equipment (UE) in a wireless network may receive Downlink Control Information (DCI) that schedules Physical Uplink Shared Channel (PUSCH) for non-codebook-based and/or codebook-based PUSCH operation. The UE may be configured with a Sounding Reference Signal (SRS) resource set for each codebook-based operation and non-codebook-based operation. The UE may transmit using a codebook base operation in a first set of PUSCH occasions and transmit using a non-codebook-based operation in a second set of PUSCH occasions. The DCI may include multiple SRS Resource Indicator (SRI) fields pertaining to different sets of PUSCH occasions.

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: Configured uplink and/or downlink grants may be managed by providing configuration parameters through higher layer signaling and then activating and/or deactivating use of provided configurations through group common PDCCH signalling that is transmitted to multiple UEs simultaneously. Similarly, enhancements to group common PDCCH signalling may be used to achieve dynamic scheduling.
