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.

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: The present application describes a WTRU including a non-transitory memory including instructions stored thereon for re-establishing a remote radio control (RRC) connection with a base station. The apparatus also includes a processor capable of executing instructions of determining, based upon a measurement in an active downlink bandwidth part (DL BWP), to initiate a random access channel (RACH) procedure. The processor also executes instructions of switching to a default uplink bandwidth part (UL BWP). The processor also executes instructions of initiating the RACH procedure. The process further executes instructions of transmitting a RA preamble using one of the RACH resources configured for the default UL BWP. The processor even further executes instructions of receiving a RA response. The processor yet even further executes instructions of switching from the default UL BWP to either an active UL BWP or another active UL BWP after re-establishing the RRC connection.

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.

Abstract: A wireless device, such as user equipment (UE) or other apparatus, like may use a transparent mode operation in which the device is not aware of the operation mode of abase station, such as a gNB or other transmission and receive point (TRP), via the use of configurations for Frame Based Equipment (FBE) and Load Based Equipment (LBE) operating modes. A base station may initiate a Channel Occupancy Time (COT) that is an FBE COT or an LBE COT, in which the wireless device follows FBE or LBE procedures accordingly. A variety of criteria may be applied in determining whether to use FBE or LBE procedures, and to switch between them. A network may use indicate the intention to switch operation mode and may do so via implicit or explicit indications. Similarly, a wireless device may autonomously switch operation mode, and may indicate the selected mode to the network.

Abstract: A wireless transmit/receive unit (WTRU) may receive a tracking reference signal comprising resources located in one or more slots. The resources may be located in one or more symbols used for receiving a demodulation reference signal. The one or more symbols in which the resources of the tracking reference signal are located may be within a first five symbols in each of the one or more slots. At least one resource of the received tracking reference signal may be frequency multiplexed with the demodulation reference signal.

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.
