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.

Abstract: A wireless User Equipment (UE) may indicate to a base station (gNB) that the UE is capable of simultaneously using sidelink resource allocations Mode 1, with scheduling by the gNB, and sidelink resource allocation Mode 2 with scheduling by the UE, and then receive from the gNB, a Medium Access Control (MAC) entity configuration comprising information for Mode 1 and for Mode 2, and Sidelink Radio Bearer (SERB) configurations which may include the mode (Mode 1 or Mode 2) for the SERB. The UE may determine grants for both modes. In case of a grant collision or overlap, the UE may use logical channel priority to select one grant over the other. The UE may change from one mode to another. The MAC entity may take actions related to feedback, BSR reporting, and SR reporting, to manage the transitions.

Abstract: The exchange of resource allocation assistance information between a requester User Equipment (UE) and an assistant UE allows the requester to make better resource allocation decisions. The assistance information may include a blacklist, a whitelist, resource allocation information, a candidate resource set, and measurement information, for example. Both UEs may have an assistance configuration to assist in the exchange of resource allocation assistance information, that may be obtained from a third apparatus, such as a base station. The configuration may include information related to when to trigger assistance, identities of UEs, and types of assistance information, for example. The requester may, based on the assistance information received, modify a candidate resource set at a Medium Access Control (MAC) layer. The requester may, at the MAC layer, determine a configured sidelink grant for a selected destination using assistance information targeting this destination.

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: Methods, systems, and devices may assist in channelization and LBT for NR unlicensed band. This may apply to NR-U from 52.6 GHz to 71 GHz and above. In an example, a method may include configuring listen before talk (LBT) bandwidth (BW) and channel occupation time (COT) sharing schemes when co-exist other radio access technology's (RAT'S) channel BW for NR-U from 52.6 to 71 GHz and above; and when LBT or a resource block (RB) set BW is set to equal to each component carrier (CC) BW Nor transmission BW, performing LBT for each CC, primary cell (PCell), primary secondary cell (PSCell), or a scheduling secondary cell (SCell) can co-schedule LBT results for other CC.

Abstract: Methods for a reduced capability New Radio (NR) device to acquire System Information (SI) transmitted by a cell, where a Radio Resource Control (RRC) message comprised of one or more Bandwidth Reduced System Information Blocks (e.g.,SIBl-BR, SIB2-BR, etc.) is received by the NR device using an SI Narrowband.
