Abstract: A wireless device can use a channel occupancy time (COT) to reserve a spectrum for sidelink positioning operations in a certain time interval. In some examples, multiple wireless devices can share the same COT for performing sidelink positioning and/or ranging operations using unlicensed or shared spectrum. Some aspects of the disclosure provide various processes for handling scenarios when channel access of the unlicensed spectrum is unsuccessful.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may detect an available bandwidth for transmission of a sidelink positioning reference signal. The transmitter UE may transmit the sidelink positioning reference signal in the available bandwidth, wherein a duration of the sidelink positioning reference signal is based at least in part on the available bandwidth. Numerous other aspects are described.

Abstract: An initiator UE may be configured to send one or more units of messages to one or more responder UEs. A unit of message may include a pre-PRS message, a PRS message and a post-PRS message. A responder UE may be configured to send one or more units of messages to the initiator UE. The pre-PRS message and the post-PRS message may be sent or received using a license spectrum. The PRS message may be sent or received using an unlicensed spectrum. The communication between the initiator UE and the responder UE may be initiated by the initiator UE identifying the responder UE from a plurality of UEs based on positioning properties of the responder UE. The positioning properties of the responder UE may include a direction, a velocity, a location confidence or a location of the responder UE, or a combination thereof.

Abstract: Aspects relate to mechanisms for sidelink reservation across frequency bands. In some examples, a sidelink device may be configured to communicate over a first frequency band (e.g., a sub-6 gigahertz frequency band) and a second frequency band (e.g., a millimeter wave frequency band) with one or more other sidelink devices. The sidelink device may further be configured to perform cross-link resource reservation for a sidelink transmission in which a resource reservation message transmitted on the first frequency band indicates reserved resources within the second frequency band for the sidelink transmission. The sidelink device may then transmit sidelink control information (SCI) within a sidelink control channel on the second frequency band and user data traffic corresponding to the SCI within a sidelink data channel on the second frequency band.

Abstract: Aspects of the disclosure relate to methods for wireless communication. A transmitting device transmits a first portion of a control message to a receiving device. The first portion includes information for decoding a second portion of the control message and for decoding data. The transmitting device then transmits the second portion to the receiving device, the second portion including additional information for decoding the data. Thereafter, the first device transmits the data to the receiving device. The receiving device receives the first portion and the second portion, and decodes the received second portion based on the information included in the first portion. The receiving device then receives the data from the second device if the received second portion is able to be decoded. The receiving device decodes the received data based on the information included in the first portion and the additional information included in the second portion.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for coordinated slot-based radar sensing. A first radar device, which may be a radar group leader, may broadcast information indicative of a wireless device group that includes the first wireless device. The first wireless device may receive, from a second wireless device that receives the broadcast information, a request to join the wireless device group that includes the first wireless device. The first wireless device may transmit, to the second wireless device based on the request, a grant or rejection to join the wireless device group that includes the first wireless device. The first wireless device may further transmit a transmission schedule to at least one wireless device of the wireless device group, where the at least one wireless device may include the second wireless device if the first wireless device transmits the grant.

Abstract: A configuration to determine a timing offset between a first wireless device and a second wireless device in order to synchronize timing between the first wireless device and the second wireless device. The apparatus determines a timing offset between a first wireless device and a second wireless device based on at least one transmission received from the second wireless device. The apparatus determines a location of a target device based at least on the at least one transmission from the second wireless device and the timing offset between the first wireless device and the second wireless device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may determine that a second wireless communication device is to communicate with a third wireless communication device using one or more beams that pass through a target area. The first wireless communication device may obtain information indicating a first object that is approaching the target area and that has a beam blocking size above a threshold. The first wireless communication device may cause the one or more of the second wireless communication device or third wireless communication device to adjust usage of the one or more beams during an expected blockage time in the target area. Numerous other aspects are described.

Abstract: Systems and methods for adjusting radar transmission parameters based on congestion level measurements are disclosed. In some aspects, a congestion level of radar signals at a location in a vicinity of a radar source may be measured or otherwise determined. In some aspects, a transmission parameter of radar signals configured for transmission to the location by the radar source may be adjusted based on the congestion levels.
