Abstract: Methods and apparatuses are described herein for LBT adaptation, beam operation, interference handling in NR above 52.6 GHz. In an example, a wireless communications device may send information on a channel. The wireless communications device may receive, from a UE, one or more ready to receives (RTRs). The wireless communications device may determine, based on a number of consecutive RTRs of the one or more RTRs, a listen before talk (LBT) mode. The channel may comprise a Physical Downlink Control Channel (PDCCH), a Physical Downlink Shared Data Channel (PDSCH), or a Physical Random Access Channel (PRACH). The LBT mode may be associated with staying or switching to a no receiver assistance mode. The LBT mode is associated with staying or switching to a receiver assistance mode.

Abstract: The present application describes an apparatus including a non-transitory memory including instructions stored thereon. The apparatus also includes a processor operably coupled to the non-transitory memory configured to execute a set of instructions. The instructions include sensing plural devices in a group to provide sidelink coordination. The instructions also include evaluating a coordination type of each of the plural devices, where the coordination type is scheduled and/or assisted. The instructions also include obtaining transmission and reception resources for the plural devices. The instruction further include determining the transmission and reception resources are dedicated or shared among the plural devices based on the coordination type. The instructions even further include determining a signaling type for each of the plural devices based on the coordination type.

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: Blind coverage for wireless devices is enhanced varying one or more transmission characteristics of a repeated transmission sent or received by apparatuses, where the repeated transmission includes, for example a Physical Downlink Shared CHannel (PDSCH) and/or a Physical Uplink Shared CHannel (PUSCH) transmissions. Varied characteristics may include a start time for each repetition, a duration for each repetition, a start frequency for each repetition, a bandwidth of each repetition, a number of repetitions for each subframe, and/or a number of repetitions for each slot. Repetitions may be within a Bandwidth Part (BWP) or span multiple BWPs. Repetitions may vary from one to another in start time, start frequency, duration, bandwidth, and slot and subframe patterns. Higher level signalling, such as Radio Resource Control (RRC) signalling may be used to control the inclusion or omission of a DeModulation Reference Signal (DMRS) in repeated transmissions.

Abstract: SL DRX mechanism is used for power savings, to address a number of sidelink non-vehicular sidelink use cases. Methods, systems, and apparatuses, among other things, as described herein may use 1) A sidelink state model to describe the UE behavior for sidelink DRX operation. The DRX operation tailored to each of the sidelink states; 2) Power savings opportunities during SL operation, in addition to stopping PSCCH monitoring; 3) Various DRX models applicable to the sidelink; 4) SL_DRX operation for the SL UnLinked state; or 5) SL DRX operation for the SL_Linked state.

Abstract: Methods and apparatuses are described herein for remote UE mobility management. Methods are proposed to consider the impact of coverage through PC5 interface when a remote UE is doing the cell (re)selection. A remote UE may select a serving cell considering the impact of coverage through PC5 interface when the remote UE and the Relay UE are in coverage of different cells. The remote UE may detect and reselect a cell via the Uu interface while it has selected a serving cell via a Relay UE. 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: 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
