Abstract: A method to reserve a directional channel, such as in an unlicensed spectrum for instance, is disclosed. In an example embodiment, the method may be performed by a receiving node, such as a user equipment (UE) for instance. In such method, the receiving node may receive an enhanced directional transmit request message from a transmitting node and transmit an enhanced directional transmit confirmation message using one or more first beams, with at least one first beam being directed in a first direction towards the transmitting node. Further, the receiving node may transmit at least one additional enhanced directional transmit confirmation message using one or more second beams, with at least one second beam being directed in a second direction towards a potentially interfering node. In the method, the second direction is a different direction than the first direction.

Abstract: Latency reduction by fast forward (FF) in multi-hop communication device and/or systems is disclosed. Packets may be received and forwarded using a codeword (CW)-based approach with and/or without per-CW CRC. A FF session may have a flow ID and packets may have sequence numbers. Packets targeted for FF may be divided into independently decodable CWs that may be transmitted in the next hop, for example, as soon as the destination is determined without waiting for an entire packet's arrival and/or for CRC verification. Low latency (e.g. FF) traffic may be indicated. CW-based FF may be extensible for an e2e RAN path from a WTRU to the last access node in a RAN. Intermediate metrics, a packet CRC and/or a per-CW CRC may be utilized for data integrity. HARQ and/or CW retransmission procedures may be implemented between network nodes for error handling.

Abstract: Systems, devices, and methods for operating in an unlicensed band are disclosed herein. In one example, a device may receive configuration information that includes a maximum channel occupancy time (MCOT) and a plurality of parameters including a plurality of transmission opportunity windows (TOWs). Based on the configuration information, the device may split a transmission into a plurality of bursts that may be grouped into sets of bursts based on how many bursts fit within a TOW. The number of bursts in a set of bursts may be less than or equal to the MCOT. The device may perform a clear channel assessment (CCA) to determine if the channel is busy and to determine a start time within the TOW for the bursts. The device may then transmit the set of bursts for that TOW, where each burst may have a burst indicator (BI).

Abstract: A method and apparatus for improving and performing mmW beam tracking is disclosed. Localization methods to improve prediction of the position of a WTRU are described, which may allow a millimeter wave base station (mB) to appropriately select a modified beam and to perform more efficient handover. WTRUs may report directional signal strength measurements to mBs, which may then be used to generate a directional radio environment map (DREM) for use in identifying secondary links to use when a primary link fails. Additional localization techniques using internal/external information for prediction are described. Historical data use and the use of data obtained from mB-mB cooperation including feedback information and reference signaling information are also described. Methods for beam tracking for directional relays and initial beam training optimization are described as well. Finally, WTRU localization precision improvement, beamwidth adaptation, and assisted beam tracking and handover methods are also described.

Abstract: Methods and apparatuses are described herein for paring an unmanned aerial vehicle (UAV) with a UAV-controller (UAV-C). For example, a UAV having a UAV wireless transmit/receive unit (UAV WTRU) may transmit, to an access and mobility management function (AMF), a non-access stratum (NAS) request message that includes a paring request indication and a UAV-controller (UAV-C) identification (UAV-C ID). The UAV-C ID may be carried in a paring request to an unmanned aerial system (UAS) service supplier (USS)/UAS traffic management (UTM) for paring authorization of the UAV with a UAV-C associated with the UAV-C ID. The UAV may receive, from the AMF, a NAS response message that includes an unmanned aerial system (UAS) identification (UAS ID) indicating that the UAV is paired with the UAV-C, wherein the UAS ID is assigned by the USS/UTM.

Abstract: Systems, methods, and instrumentalities are disclosed herein for pre-processing for channel state information (CSI) compression in wireless system. A WTRU may receive configuration information that indicates a reference signal and a data processing model for channel state information (CSI) compression. The WTRU may determine CSI associated with a channel using the reference signal. The WTRU may determine a channel condition associated with pre-processing. The WTRU may select a pre-processing type from a plurality of pre-processing types based on the data processing model and the determined channel condition associated with pre-processing. The WTRU may pre-process the CSI associated with the channel based on the selected pre-processing type. The WTRU may generate compressed CSI by compressing the pre-processed CSI using the data processing model for CSI compression. The WTRU may send the compressed CSI to a network.

Abstract: A WTRU may track parameters associated with the WTRU or target WTRUs. The parameters may be associated with positioning and/or sidelink communications. The WTRU may receive a configuration for transmission of reference signals to target WTRUs. The WTRU may transmit one or more reference signals on one or more configured sidelink resources. The WTRU may receive respective measurement report(s) from respective target WTRU(s) (e.g., a target WTRU may receive a reference signal transmitted by the WTRU and send an associated measurement report). The WTRU may be configured to send the received target WTRU measurement(s) to the network entity. The WTRU may send each of the received measurements. The WTRU may send the received measurement(s) if condition(s) are satisfied. For example, if a first measurement associated with a first measurement report from a first target WTRU exceeds a first threshold, the WTRU may send the first measurement to the network entity.

Abstract: A cellular communications network may be configured to leverage a millimeter wave (mmW) mesh network. Base stations may be configured to operate as mmW base stations (mBs). Such base stations may be configured to participate in the mmW mesh network and to access the cellular communications network (e.g., via cellular access links). A network device of the cellular communications network (e.g., an eNB) may operate as a control entity with respect to one or more mBs. Such a network device may govern mesh backhaul routing with respect to the cellular communications network and the mmW mesh network. Such a network device may configure the mmW mesh network, for example by performing a process to join a new mB to the mmW mesh network. A WTRU may send and receive control information via a cellular access link and may send and receive data via the mmW mesh network.

Abstract: A cellular communications network may be configured to leverage a millimeter wave (mmW) mesh network. Base stations may be configured to operate as mmW base stations (tnBs). Such base stations may be configured to participate in the mmW mesh network and to access the cellular communications network (e.g., via cellular access links). A network device of the cellular communications network (e.g., an eNB) may operate as a control entity with respect to one or more niBs. Such a network device may govern mesh backhaul routing with respect to the cellular communications network and the mmW mesh network. Such a network device may configure the mmW mesh network, for example by performing a process to join a new mB to the mmW mesh network. A WTRU may send and receive control information via a cellular access fink and may send and receive data via the mmW mesh network.
