Abstract: Measurement modeling and filtering may include configurable cell quality derivation method is used for multi-beam based NR networks; a common measurement model that considers different characteristics of the two measurement signals, NR synchronization signal and additional reference signal; and a multi-level measurement filtering approach that handles different mobility scenarios in an NR network. Measurement configuration and procedures may include a measurement gap design during which UE may use to perform measurements for beam sweeping based NR networks; a group of triggering events that may be used to trigger UE mobility management in an NR network; a content format that may be used for the transmission of UE measurement report; a measurement object design (the object on which a UE may perform the measurements) to reduce UE measurement overhead and cost; and a downlink measurement based inter-cell handover procedure that may be used in an NR network.

Abstract: Techniques for congestion management in a communication network are contemplated. For example, a wireless transmit receive unit (WTRU) may include a Radio Resource Control (RRC) layer and a Non-Access Stratum (NAS) layer. The RRC layer may receive an indication for a service, for example from the NAS. The indication may be interpreted as a request for the particular service indicated. For example, the indicated service may correspond to at least one of: a mobile originated (MO) voice communication, a circuit switched fallback (CSFB) supplementary service (SS), or a MO short message service (SMS). The RRC layer may receive a signal from a network indicating that one or more services provided by the network are allowed. The RRC layer may send a connection request to the network for the service sought by the NAS if that service is one of the one or more services allowed.

Abstract: Multiple mobility sets are maintained for nodes of radio networks. The sets comprise information such as: transmit and receive point identities; cell identities; beam identities; frequency channels; channel bandwidth; and black lists. The sets may be defined at different levels, such as network and physical (PHY) level. A network mobility set, e.g., a new-radio (NR) mobility set may, be determined by the gNB, the cell, the UE, or another device. Multiple radio access network nodes and UEs may exchange mobility set information to achieve a distributed mobility solution. A UE may monitor its orientation relative to a TRP, e.g., via use of an onboard MEMS gyroscope, and alter its beamforming parameters in response to changes in orientation and/or changes in TRP connection strength. Cell selection and reselection for beam based networks may use Single Frequency Network (SFN) broadcast of initial access signals without beam sweeping.

The transmission time interval includes a control information region including plural beams. The interval also includes a downlink transmission channel region including plural beams. The frame structure is configured for downlink control information to be swept through the time interval. The frame structure is also configured for an uplink or downlink grant resource subsequently to be swept through the time interval. The present application is also directed to a method for configuring user equipment.

Abstract: The present application describes a method including a step of providing a sidelink (SL) synchronization signal (SS) burst over a time period, the SL SS burst including a slot including OFDM symbols. The method also includes a step of restricting, in a first OFDM symbol of the slot, transmission of a synchronization signal block (SSB) over resource blocks (RBs). The method further includes a step of transmitting, from a user equipment (UE) via plural symbols after the first symbol, the SSB over the RBs in new radio (NR) SL SS and physical broadcast channel (PBCH) (NR SL SS/PBCH) to a gNB. The present application also describes a method for discovering a vehicle group in vehicle to anything (V2X) communication range.

Abstract: A method may perform random access subject to Listen-Before-Talk (LBT) in an NR-U Sewing Cell with multiple models. Enhancements may be to the Random Access Preamble Transmission procedure to enable autonomous BWP switching or sub-band in the event the channel is busy for the active UL BWP.

Abstract: Logical Channel Prioritization (LCP) may be enhanced by accounting for Quality of Service (QoS) attributes of single hop and multi-hop paths. QoS attributes may be communicated as a QoS budget comprising a number of attributes, or as a single composite QoS “resistance” factor that quantifies the compounded impact of number of hops, latency, load conditions, and the like. The QoS budget or resistance may dynamically adjusted, and may be used by LCP to provide differentiated uplink resource allocation to data of the bearer or logical channel subject to different transmission paths between the transmitter and the receiver, for example. QoS budget and resistance information may be used to, e.g., enhance Buffer Status Report (BSR) and Scheduling Request (SR) operations.

Abstract: Methods and apparatuses are described herein for prioritizing sidelink communication transmissions. In accordance with one example embodiment, an apparatus may transmit, to a network node, assistance parameters associated with sidelink communication comprising quality of service (QoS) parameters. The apparatus may receive, from the network node, configuration parameters associated with sidelink communication that comprise a logical channel configuration, a mapping of a QoS parameter to a sidelink radio bearer, and a mapping of the sidelink radio bearer to a sidelink logical channel. The apparatus may receive a sidelink resource grant and may select, based on the logical channel configuration, one or more sidelink logical channels to be served by the sidelink resource grant. The apparatus may transmit a generated a medium access control (MAC) protocol data unit (PDU), comprising data associated with the selected one or more sidelink logical channels, using the received sidelink resource grant.

Abstract: Flexibly configured containers consisting of resources within time-frequency blocks may be used to support multiple numerologies in new radio architectures. Uplink control may be defined in resources within a container, or in dedicated resources, by various nodes. Sounding reference signal resources may be dynamically configured for each numerology. The sequence length may be adapted, as well as the time domain location of symbols. Time, frequency, and orthogonal resources may be allocated via a downlink control channel or a radio resource control. Sounding reference signals may be pre-coded, and pre-coding weights may be based on a codebook or non-codebook approaches, e.g., via a radio resource control or a downlink RRC or DL control channel. Pre-coded sounding reference signals may be adapted to user equipment antenna configuration. Further, NR-SRS may be used as UL demodulation RS (DM-RS).

The processor also executes the instruction of initiating a random access (RA) procedure. The processor also executes the instruction of determining whether a configured contention-based physical random access channel (PRACH) resource overlaps with the first BWP. The process further executes the instruction of transmitting a RA preamble including the configured contention-based PRACH resource to the base station. The processor even further executes the instruction of receiving a RA response from the base station.

Abstract: It is recognized herein that, in some cases, URLLC transmissions may preempt a scheduled eMBB transmission. Thus, in accordance with one embodiment, resources are allocated for URLLC data transmission in a manner that minimally impacts eMBB data transmissions. In an example code block groups are configured for efficient multi-bit A/N feedback. Multi-bit A/N methods are disclosed with and without explicit resource allocation. Various preemption mechanisms are also described herein including, for example, puncturing, dropping the tail end of a transport block, and increasing rate matching.

Abstract: 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.
