A method performed by a wireless transmit/receive unit (WTRU) may include sending, to a network, a registration message indicating the WTRU is capable of device-to-device (D2D) communication and sending a request for assistance in discovering at least one other WTRU in proximity to the WTRU. The method may include receiving, from the network, in response to the request for assistance in discovering the at least one other WTRU, assistance information including one or more of a unique identifier or filtering information. The method may include performing, using the assistance information, a device discovery procedure to discover the at least one other WTRU, wherein the device discovery procedure comprises at least one of: monitoring for signals from the at least one other WTRU using the assistance information, or sending a discovery announcement based on the assistance information and transmitting application data directly to the at least one other WTRU.

Resource allocation for device-to-device (D2D) communications

The disclosure pertains to methods and apparatus for operation by a wireless transmit/receive unit (WTRU). In one embodiment, a method includes receiving from a first device, a request to send a transmission to a second device via resonance magnetic coupling, the request including capability information indicating a set of load termination states supported by the first device; sending to the first device, measurement configuration information, the measurement configuration information including information indicating (1) timing and/or frequency information to schedule the measurement of a signal strength received by the first device; and (2) at least one load termination state of the set of load termination states to be used by the first device when performing measurements; receiving from the first device, measurement information resulting from measurements performed by the first device in accordance with the sent measurement configuration information; determining a load termination state for the first device based on the measurement information; and sending to the first device, information indicating the determined load termination state for the first device.

Methods and apparatus for load-based access control in resonance magnetic coupled networks

A base station may sense, on a cell using unlicensed spectrum, that the unlicensed spectrum is available for transmission. The base station may transmit, after sensing that the unlicensed spectrum is available, consecutive subframes. Each subframe may include a physical downlink control channel and a physical downlink shared channel.

Wireless operation in unlicensed spectrum

Wireless transmit/receive units (WTRUs) may include unmanned aerial vehicles (UAVs). The WTRUs/UAVs may cooperate to exchange channel busy ratio (CBR) and/or CBR statistics of one or more (e.g., all) the carriers that the WTRUs/UAVs monitors with each other for carrier selection/carrier reselection. A network may provide one or more inputs on carrier selection. For example, a network may provide one or more inputs on carrier selection based on the congestion that the network infers (e.g., through the CBR measurements reported by the WTRUs/UAVs and/or through its own measurements). MAC/PHY layers may be configured to perform transmit adaptation during PDCP packet duplication. For example, the carrier aggregation capability of receivers may be considered to adapt the number of transmissions per carrier. Based on the carrier aggregation capability of the receivers, the number of transmissions at one or more (e.g., every) carriers may be optimized jointly across carriers.

Carrier aggregation for wireless transmit/receive unit

Systems, methods, and instrumentalities are disclosed herein associated with enabling target localization with bi/multi-static measurements in new radio (NR). Bi-static or multi-static configurations with potential targets may be formed with nodes (e.g., WTRUs, gNBs, etc.) of mobile wireless communication systems, for example, to enable target localization applications. Target localization may be enhanced based on using determined configurations to reduce target localization estimation errors.

Enabling target localization with bi/multi-static measurements in NR

Method, apparatus and systems are disclosed. In one representative embodiment, a method may be implemented by a wireless transmit/receive unit (WTRU) for communication via a network access point (NAP). The method may include the WTRU receiving from the NAP a set of preambles and corresponding propagation delay related thresholds and determining propagation delay related information associated with a distance between the WTRU and the NAP or a location in a coverage of the NAP. The method may further include selecting a subset of preambles from the set of preambles based on the determined propagation delay related information, randomly selecting a preamble from the selected subset of preambles, and sending the randomly selected preamble to the NAP.

Methods, apparatus, systems and procedures for distance dependent random access channel (RACH) preamble selection in non-terrestrial networks (NTNs)

Systems, devices and methods for a backscatter measurement based multiple RACH preamble transmissions are disclosed. A WTRU may receive a JCS-RS configuration comprising a minimum RACH preamble retransmission interval. The JCS-RS configuration may comprise a JCS backscatter power fraction (λ) of the WTRU transmit power (P). The WTRU may transmit a RACH preamble in a RACH occasion corresponding to a preferred SS/PBCH Index using an initial WTRU transmit beam, having an associated first RA-RNTI value. The backscatter power (P) may be measured using the WTRU receive beam corresponding to the WTRU transmit beam used for the RACH preamble transmission. On a condition that P>λP, the WTRU may retransmit the RACH preamble after a retransmission interval, on resources associated with a second RA-RNTI value. The WTRU may be configured for monitoring the PDCCH common search space with the first RA-RNTI and the second RA-RNTI, for respective RAR window intervals.

Joint communication and sensing aided random access channel

Systems, methods and instrumentalities for a distributed detect and avoid (DM) framework for unmanned vehicles, such as unmanned aerial vehicles (UAVs). The systems, methods and instrumentalities may include a wireless transmit/receive unit (WTRU) associated with a vehicle. The WTRU may include a memory and a processor. The processor may be configured to store a trajectory of the vehicle and to send a message indicative of a conflict between the trajectory of the vehicle and a trajectory of another vehicle. The processor may be configured to receive a message from the other vehicle that is indicative of one or more conflicts and to determine a list that includes the vehicle(s) associated with the one or more conflicts. The processor may be configured to determine a resolution that addresses the conflict(s) associated with the list.

Methods and apparatuses are described herein for providing Hybrid Automatic Repeat Request (HARQ) techniques for a non-terrestrial network. For example, a wireless transmit/receive unit (WTRU) may transmit, to a satellite base station (BS), uplink (UL) feedback that includes configuration information for redundancy versions (RVs) and cross redundancy versions (cRVs). The WTRU may receive one or more first RVs associated with a first transport block (TB). The WTRU may receive one or more second RVs associated with a second TB and at least one cross redundancy version (cRV) associated with the first TB and second TB. The cRV may include parity bits generated from both the first TB and second TB. If at least one of the first TB or the second TB is unsuccessfully decoded, the WTRU may decode the first TB and second TB jointly based on the at least one cRV.

Hybrid automatic repeat request (HARQ) techniques for non-terrestrial networks

Methods and apparatus are described. A method, implemented in a wireless transmit/receive unit (WTRU) includes monitoring a first control channel search space (SS) associated with a first normal beam set comprising a first beam set. The WTRU initiates extended monitoring and monitors, subsequent to a trigger based on a measurement by the WTRU, a control channel SS associated with an extended beam set comprising the first beam set and one or more additional beam sets. The WTRU determines a second beam set from the extended beam set. The determination is based on a received control channel beam switch command or based on a control channel SS in which a beam switch command is received. The WTRU monitors a second control channel SS associated with a second normal beam set comprising the determined second beam set.
