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

UEs' mobility may have a significant impact on sidelink communications and Uu mobility procedures of UEs participating in SL communication or SL Group Communication. Methods devised to optimize handover procedures, cell reselection procedures, and transition to RRC_IDLE and RRC_INACTIVE for UEs with ongoing SL communications. Methods are disclosed herein for PLMN selection for UEs requiring sidelink communication or with active sidelink communication, as well as, methods to provide priority-based resource allocation while using exceptional transmit resource pools. Also, provided are SL group management procedures to deal with impacts of UE mobility.

NR V2X mobility

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

Network Slice Selection Assistance information (NSSA1) may be signaled between User Equipment (UE) and a network. NSSA1 sent from the network to the UE may include, for example. Operating Frequency Band (OFB) for each Single NSSAI(S-NSSA1) in the NSSAI, as well as a Radio Access Technology (RAT) Frequency Selection Priority (RFSP) index, which the network configures as a part of UE access and mobility; subscription, during a UE registration procedure. RAT restrictions may be enhanced to indicate to the UE that certain slices are not accessible via certain RATs. A UE may be provided by the network with an alternative NSSAI and corresponding OFBs for each S-NSSAI thereby indicating to the UE that these S-NSSAI would have been allowed had they been requested. A UE may be able to choose an alternative Allowed NSSAI and send a registration update request to the network.

Frequency range driven network slicing

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

Access category management objects may be configured for use in support of access category configurations of a user equipment (UE). Various methods for a UE configuration with access categories are disclosed. Signaling methods by a radio access network of access barring parameters such as a signaling method for a partial list of access barring parameters with explicit signaling of access category indexes and a signaling method for a full list of access barring parameters where access categories are signaled using a bitmap are disclosed. Access control parameters and an access control architecture in terms of access control function distribution within the UE protocol sublayers, solutions that address the impact of access control in a connected mode on a buffer status report, logical channel prioritization and flow control between the UE AS and UE NAS, and details regarding access barring checks are also disclosed.

A first apparatus in a wireless communication system, the first apparatus including circuitry configured to trigger a Random Access Channel (RACH) procedure; select a two-step RACH procedure from among a plurality of RACH procedures as a RACH type to be performed; select a MsgA transmission resource; transmit a MsgA; and monitor for a network response from a second apparatus.

Apparatus, system and method for performing two-step RACH

Methods, systems, and apparatus designed to support flexible carrier bandwidths in new radio. Multiple carrier bands may be combined into a single composite carrier depending on channel availability in the carrier bands. A composite carrier indicator (CCI) indicates to network devices, the available carrier bands within the channel occupancy time. In addition, bandwidth part inactivity time is suspended when channel access is not available.

Channelization and BWP

Layer 2 structures and procedures may be used for beam management in new radio networks. In a first example, a new radio layer 2 structure may be used to facilitate beam management at the medium access control sublayer. In a second example, new radio feedback mechanisms may be signaled between peer medium access control entities and used to assist with beam management. In a third example, new radio beam management procedures may include new radio beam training, new radio beam alignment, new radio beam tracking, or new radio beam configuration. In a fourth example, new radio connection control procedure may include new radio initial access or new radio mobility management.

Beam management

An electronic device including circuitry configured to send a request to a core network, wherein the request informs the core network that the electronic device is capable of aggregating data and relaying data from other electronic devices; receive one or more aggregation policies from the core network, wherein the one or more aggregation policies provide parameters that instruct how the electronic device is to aggregate and relay data; receive data from the other electronic devices; aggregate the data from the other electronic devices based on the parameters; and send the aggregated data to the core network.

Electronic device and methods for performing data aggregation in a 5G user equipment

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.
