Abstract: User equipment (UE) in beam-centric telecommunications cell may use a variety of listen-before-talk (LBT) procedures and hybrid channel access procedures for uplink transmissions are on different beams and configured or scheduled in contiguous or non-contiguous mode. UE behavior may be based on the LBT result across the different beams. A gNB may indicate LBT occasions to UEs. The UL numerology may be adjusted without LBT while near the end of a gNB's maximum channel occupancy time (MCOT). A gNB may use LBT procedures, before down link transmissions, using data, control, and reference signals, etc., across different beams.

Abstract: Methods and apparatuses are described herein for Multicast/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.

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 and apparatuses are described herein for Intra-UE Prioritization in uplink (UL) transmissions. In an example, an apparatus may receive first information indicating a first uplink grant associated with a first transmission and second information indicating a second uplink grant associated with a second transmission. The apparatus may determine, based on the first information and the second information, that the first transmission and the second transmission overlap at least partially in time. The apparatus may determine a first priority associated with the first transmission and a second priority associated with the second transmission. The apparatus may then cause, based at least in part on the first priority and the second priority, at least one of: prioritization of one transmission over another transmission, or preemption of the first transmission by the second transmission.

Abstract: The present application may describe a method for obtaining channel access in a network. The method includes selecting, via a gNodeB, a spatial filter to perform listen before talk (LBT). The method includes detecting, via the gNodeB, a channel in an idle state. The method includes obtaining a directional channel occupancy time (COT). The method also includes transmitting a channel access indicator transmission (CAI-T) on a beam. The method further includes receiving a channel access indicator response (CAI-R). The method further includes sensing the channel is clear (e.g., via short channel sensing and the spatial filter). The method includes sending, via the channel, information to the node using one or more spatial filters of the second set of spatial filters. Other embodiments may include corresponding computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform the actions of the methods.

Abstract: An apparatus including a non-transitory memory including instructions stored thereon for monitoring synchronous signals and physical broadcast channels (SSBs) from a network node. The apparatus also includes a processor, operably coupled to the non-transitory memory, configured to execute a set of instructions. The instructions include configuring the apparatus for a STTC (SSB Transmission Timing Configuration). The STTC is a time interval with plural locations accommodating transmission of the SSBs. The instructions also include monitoring the STTC for the SSBs. The instructions further include determining a first one of the SSBs in a first slot of a subframe in a scheduled SSB transmission in the STTC has been transmitted at a first scheduled location, where the transmission of the first one of the SSBs is based upon confirmation of a successful Listen Before Talk (LBT) available channel prior to the scheduled SSB transmission in the STTC.
