Abstract: The performance of user equipment (UE) using sidelink radio communications may be improved by providing the UE with sidelink configuration information pertaining to modes, functions, channels, signals, and/or resources for use in sidelink communications. For example, a UE may receive information indicating a sidelink mode, e.g., a transmit-only, receive-only, or a transmit and receive mode. Sidelink configuration may include indications of signals and/or channels for use in sidelink transmit and/or receive communications, etc.

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: A user equipment, (UE) and a network may communicate to dynamically adapt the steering of traffic over both 3 GPP and non-3GPP accesses for uplink, downlink, or both. For example, a UE may request from the network the ability to dynamically adapt uplink traffic and the network may also apply the same traffic adaptation on downlink traffic. The UE and network may communicate dynamic traffic adaptation using traffic steering rules, e.g., via control plane NAS protocol, and with user plane signalling, e.g., via user plane PMF protocol.

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: Cross scheduling of a component earner for vehicle sidelink communications may be achieved by explicit configuration, implicit configuration, or a combination thereof. A user equipment, UE, may be configured with a resource pool configuration, for example, pertaining to multiple resource pools, resource group partitions, and/or component carrier groups. The UE may be configured to use fields such as a Carrier Indication Field and/or a Carrier Group Indication Field contained in a Physical Sidelink Control Channel, PSCCH. The UE may use the resource pool configuration in combination with where the UE is able to decode the PSCCH, with or with the CIF and/or CGIF, to determine a scheduled Component Carrier, CC, for sidelink communications.

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.
