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.

Channelization and LBT for NR unlicensed band from 52.6 GHz and above

LBT adaptation, beam operation, and/or interference handling may be performed by wireless communication devices in NR above 52.6 GHZ. In an example, a wireless communications device may send information on a channel. 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 wireless communications device may receive, from a user equipment (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 LBT mode may be associated with staying or switching to a no receiver assistance mode or staying or switching to a receiver assistance mode.

Methods and systems of LBT adaptation and beam operation with interference handling for supporting NR above 52.6 GHz

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.

Mechanism for SSB transmission in NR-U

A system, apparatus, method, and computer program product used in a new radio (NR) system includes a processor and a memory storing computer-executable instructions that when executed by a processor cause a first user equipment (UE) having a plurality of antenna panels to perform Vehicle-to-Everything (V2X) sidelink (SL) radio communication with a second UE. Systems, apparatuses, methods, and computer program products for performing a discovery procedure in a NR system, for performing a reference signal communication in a NR system, controlling a timing offset in a NR system, and performing beam management in a NR system are also described.

Apparatus for performing multi-panel transmission for new radio vehicle to everything

Methods and systems are disclosed for resource management on Sidelink for vehicle to everything (V2X) scenarios. Example methods and systems for a Resource Structure on Sidelink are disclosed. Control and data channels may be Frequency Division Multiplexed (FDMed) or Time Division Multiplexed (TDMed) with an Orthogonal Frequency Division Multiplexing (OFDM) waveform. Example methods and systems for a Resource Configuration on Sidelink are disclosed. The resource configuration may be statically configured or may be locally configured. Example methods and systems for Assisted Resource Allocation are disclosed. Assisted Sensing may be performed by a group lead or RSU and local scheduling may be performed by a group lead or RSU.

Resource management for 5G eV2X

Methods, systems, and deices may assist in reducing the possibility that a reduced capability NR device misses a paging message due to the termination of PTW. Methods, systems, and devices may enable a UE to dynamically turn on and off eDRX mode of operation or change eDRX configuration based on its traffic profiles.

eDRX enhancement for reduced capability device

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.

Coverage enhancement for reduced capability new radio devices

Switching between Orthogonal Multiple Access (OMA) and Non-Orthogonal Multiple Access (NOMA) modes of a user equipment (UE) can be determined and indicated by a gNB to a UE at an RRC connected state using one or more of the following schemes: at an RRC (Radio Resource Control) layer with an RRC configuration message, at a MAC (Medium Access Control) layer with MAC CE (MAC control element) signaling, at a PHY (Physical) layer with DCI (Downlink Control Information) signaling, jointly with RRC configuration and DCI signaling, and/or jointly with RRC configuration and MAC CE signaling. The OMA or NOMA mode that the UE operates after the transition may be requested by the UE, indicated by the gNB, and/or may be based on one or more rules for OMA-NOMA switching.

Configuration and signaling for UL NOMA operations

Non-Orthogonal Multiple Access (NOMA) transmissions are described herein in which sequence collision is mitigated or eliminated by exploiting the randomness nature of user specific reference bits and data bits. Further, methods, systems, and devices that use NOMA for small data transmissions are disclosed.

Small data transmission with non-orthogonal multiple access

Sub-band (SB) indications and listen-before-talk (LBT) outcomes may be used to adjust communications between devices such as wireless terminals and base stations. For example, a wireless terminal may receive SB indications including SB configurations and/or LBT outcomes of a base station, and other information such as a remapped CORESET. Similarly, a terminal may determine that a physical resource block (PRB) is invalid based at least in part on whether the PRB overlaps with a guard band. The terminal may be arranged to adjust its searches and transmissions based on received SB indications, and to provide the base station with LBT outcomes of the terminal.

Sub-band operations in unlicensed spectrums of new radio

A user equipment (UE) determines sidelink resources for use in vehicle wireless communications. Initial beam establishment uses a Sidelink Synchronization Signal (SLSS), a Sidelink Channel State Information Reference Signal (SL-CSI-RS), or a Sidelink Demodulation Reference Signal (SL-DMRS). Beam refinement may then be conducted either by UEs in communication with each other, or by just one of the UEs. A base station such as a gNB may assign resources for a dedicated sidelink carrier or a shared licensed sidelink carrier, e.g., dynamically, as pre-configured by RRC, or based on activation and deactivation. In such cases, initial beam establishment and refinement may include gNB controlled beam forming at a connectionless stage, gNB controlled beam forming at connection stage with scheduling DCI transmitted to Tx UE only, or gNB controlled beam forming at connection stage with scheduling DCI transmitted to both Tx UE and Rx UE.

Beam management for new radio vehicle communications

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.

Apparatus, system and method for performing two-step RACH

Methods and apparatuses are described herein for prioritizing sidelink communication transmissions. In accordance with one example embodiment, a WTRU may include a processor, configured to receive vehicle-to-x communication (V2X) configuration parameters from a V2X network node. The V2X communication parameters may be associate with sidelink communications for a V2X service. The WTRU may send a user equipment (UE) information message to a gNB. The UE information message may include quality of service (QoS) information associated with the V2X service. The WTRU may further receive a radio resource control (RRC) configuration message from the gNB. The RRC configuration message may include an indication of a logical channel to be used for communication sidelink data associated with the V2X service, and one or more logical channel configuration parameters for the logical channel to be used for communication of the sidelink data associated with the V2X service. The WTRU may send at least one sidelink transmission comprising the sidelink data associated with the V2X service.
