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

Methods, apparatus, and systems are described for assistance information from the UE to network side, e.g., enabling faster decision-making for secondary cell group deactivation in 3GPP MR DC/CA deployments. According to some aspects, instructions for UE behavior upon MR DC/CA secondary cell group activation are provided in a secondary cell group deactivation message to reduce delays for a UE triggered secondary group activation. RRC signaling ambiguities for conditional PSCell addition/change may be resolved by a synchronization message between a main node and a secondary node to avoid delays and signaling errors.

Activation/de-activation mechanism for one SCG and Scells, and conditional PSCell change/addition

A wireless transmit/receive unit may request, from a core network, authorization for creating one or more personal networks of one or more devices. After being granted authorization, the UE may be enabled to create a personal network and to cause a PDU session for the personal network to be established with the core network. The UE may enable members of the personal network to send data associated with the personal network via the PDU session.

Authorization, creation, and management of personal networks

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 method and apparatus are described for supporting a two-stage device-to-device (D2D) discovery using a D2D interworking function (IWF). A D2D IWF component may be configured to perform mapping between an application running on an application server and a third generation partnership project (3GPP) network, and provide a set of application programming interfaces (APIs) to allow discovery to be provided as a service to D2D applications. An application identifier may be mapped to a 3GPP identifier. Further, a method and apparatus are described for performing client-server discovery. A first wireless transmit/receive unit (WTRU) may be configured for a listen-only operation, and a second WTRU may be configured to transmit beacons. The first and second WTRUs may perform a radio access network (RAN) discovery procedure at an access stratum (AS) layer. A method and apparatus for performing charging for D2D service using a D2D IWF are also described.

Method and apparatus for supporting proximity discovery procedures

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

A method and apparatus for transmitting uplink control information (UCI) for Long Term Evolution-Advanced (LTE-A) using carrier aggregation is disclosed. Methods for UCI transmission in the uplink control channel, uplink shared channel or uplink data channel are disclosed. The methods include transmitting channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), hybrid automatic repeat request (HARQ) acknowledgement/non-acknowledgement (ACK/NACK), channel status reports (CQI/PMI/RI), source routing (SR) and sounding reference signals (SRS). In addition, methods for providing flexible configuration in signaling UCI, efficient resource utilization, and support for high volume UCI overhead in LTE-A are disclosed.

Uplink control information transmission methods for carrier aggregation

An apparatus in accordance with the present application may monitor a sidelink (SL) connection. The apparatus includes processing circuitry that receives signals in a protocol stack to perform SL-radio link monitoring (SL-RLM), and determines, according to the signals, whether a SL-radio link failure (RLF) has occurred. The signals may include hybrid automatic repeat request (HARQ) feedback. In a case that the signals include a HARQ-NACK, the processing circuitry determines that the SL-RLF has occurred. The processing circuitry further receives configuration information related to the SL-RLM for the signals, the configuration information including configurations for measurement quantities of the signals and a condition for declaring SL-RLF, configures, according to the configuration information, lower layers of the protocol stack for the SL-RLM for the signals, and performs SL-RLM measurements of the measurement quantities.

RLM and RLF procedures for NR V2X

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.

Sidelink enhancements resource allocation assistance information

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.
