    Abstract: Methods and apparatuses for receive (Rx) beam selection are described herein. A wireless transmit/receive unit (WTRU) may be configured to receive, from a base station (BS), configuration information for joint communication and sensing (JCS) reference signals. The configuration information may include resources for reference signal transmission and resources for measurement reporting. The WTRU may be further configured to receive, from the BS, an indication to activate a subset of the resources for JCS reference signal transmission. The WTRU may be further configured to transmit, a plurality of JCS reference signals using the activated subset of resources for reference signal transmission. The WTRU may be further configured to measure, via a plurality of Rx beams, a backscatter power associated with each of the transmitted plurality of JCS reference signals. The WTRU may be further configured to calculate beam blockage statistics based on the measured backscatter power.

    Abstract: Methods and apparatuses for sensing a cluster of closely-spaced objects are described herein. A method implemented in a first station (STA) may include receiving, from a second STA, a multicast message including information indicating a request for one or more STAs to participate in a sensing procedure and information indicating one or more sensing parameters. The method may include transmitting, to the second STA, an indication that the first STA is capable of participating in the sensing procedure based on the one or more sensing parameters, the indication including information associated with a participation ability of the first STA. The method may include receiving, from the second STA, configuration information for performing the sensing procedure sensing as a transmit responder based on the information associated with the participation ability of the first STA, and performing the sensing procedure as the transmit responder by transmitting beamformed signals.

    Abstract: Methods and apparatuses are described herein that facilitate mesh network communication by a millimeter wave base stations (mBs) or WTRUs as nodes of a directional mesh network with other nodes of the directional mesh network. The mB or WTRU may include a directional antenna configured to transmit and receive signals in specific directions during the mesh network communication to define a directional mesh network. The mBs or WTRUs may transmit transmission request messages to neighbor nodes, wherein the transmission request messages include transmission slot allocation bitmaps and channel quality indicator information (CQI). Then response messages from the neighbor nodes may be received, wherein the response messages include receive slot allocation bitmaps and resource allocation decisions. The mBs or WTRUs may then update their transmission slot allocation bitmaps based on the received response messages and transmit data packets in specific directions based on the updated transmission slot allocation bitmap.

    Abstract: Methods and apparatus may perform dual-band or multi-band mesh operations. A dual-band mesh station (MSTA) capable of operating in an O-band and a D-band may seek to join a mesh network, and may receive O-band beacons from at least one MSTA in the mesh network, where the O-band beacons may include D-band mesh information. The joining MSTA may transmit D-band beacons in a time-period specified by the O-band beacon, and on a condition that a beacon response message is received, may further transmit D-band association information via O-band management frames to join mesh network on the D-band. The joining MSTA may perform contention-free scheduled access in the D-band while sharing D-band transmission information in the O-band to enable concurrent communication in the D-band by neighboring multi-band MSTAs.

    Abstract: Systems, methods, and instrumentalities are provided to implement granting a license to a millimeter wave base station (mB) in a wireless network. The mB may send a license request. The license request may be associated with a beam direction in a frequency band. The mB may receive a measurement schedule. The mB may take an interference measurement, e.g., in accordance with the measurement schedule. The interference measurement may be associated with one or more of the beam direction, a frequency band, or an assigned time period. The mB may send the interference measurement to the license coordinator. The mB may receive a temporary license for the beam direction in the frequency band. The temporary license may include a first transmit power restriction. The mB may receive an instruction to send a signal burst. The mB may receive a non-temporary license. The non-temporary license may include a second transmit power restriction.
