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.

Sidelink enhancements resource allocation assistance information

An electronic device including a transceiver to communicate with a network; and circuitry. The circuitry is configured to perform beam failure detection on a monitored cell; detect a beam failure on the monitored cell; determine at least one new set of candidate beam reference signals (CB-RSs) from at least one set of CB-RS configured for the device; determine if any CB-RS in the at least one new set of CB-RSs meets a criterion, and in a case that any CB-RS in the at least one new set of CB-RSs meets the criterion: select a beam corresponding to a CB-RS in the new set that meets the criterion as the new beam, and indicate the selected new beam to the network; and in a case that no CB-RS in the new set of CB-RS meets a criterion, indicate to the network that no CB-RS in the new set meets the criterion.

Apparatus, system, method, and computer-readable medium for performing beam failure recovery

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

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.

Prioritization procedures for NR V2X sidelink shared channel data transmission

A Channel Access Indicator (CAI) may be employed in New Radio Unlicensed (NR-U) to indicate channel occupation by a node to nodes outside its cell, indicate channel occupation by a node to nodes within its cell to aid spectral reuse, and to trigger a handshake between nodes within a cell to ensure that receiver has clear channel to transmit and receive.

Channel access indication for spectral reuse, power savings and coexistence

Systems and methods for PDCCH reliability are disclosed. The PDCCH may be improved by introducing multi-TRP, multi-beam or repeated, PDCCH transmission and reception. In some methods and systems, PDCCH is transmitted on multiple CORESETs (Control Resource Set), where each CORESET is associated with a TCI state. In some cases, it is beneficial if a UE can determine that multiple received DCIs are duplicates, in order not to duplicate the corresponding UE action. Methods and systems for DCI duplication determination are disclosed. In some methods and systems, PDCCH is transmitted in a single CORESET, where the CORESET is associated with multiple TCI states. Various ways to apply the different TCI states to different disjoint frequency parts of the CORESET or the whole CORESET are proposed. Furthermore, the TCI state used for PDCCH may be used for subsequent PDSCH reception as well, in some cases. The disclosure also presents methods and systems on how to apply multiple TCI states of a received PDCCH to a subsequent PDSCH reception.

Reliability enhancement for PDCCH

A first apparatus including a processor; and a memory storing computer-executable instructions that when executed by the processor cause the first apparatus to: receive, from a second apparatus, information including Discontinuous Reception (DRX) configurations, wherein one of the DRX configurations is a first active DRX configuration and other DRX configurations are candidate DRX configurations; perform Physical Downlink Control Channel (PDCCH) monitoring in accordance with the first active DRX configuration; monitor signaling from the second apparatus for an indication that is used for adapting the first active DRX configuration; receive from the second apparatus an indication for adapting the first active DRX configuration into a second active DRX configuration; based on the indication for adapting the first active DRX configuration into the second active DRX configuration, adapt the first active DRX configuration into the second active DRX configuration; and perform PDCCH monitoring in accordance with the second active DRX configuration.

DRX configuration in new radio
