Abstract: Methods, systems, and devices for wireless communications are described in which interference between wireless devices that employ radar detection may be reduced or mitigated. A user equipment (UE) may transmit radar signals for target detection and collision avoidance in accordance with an interference mitigation procedure. The interference mitigation procedure may be based on measurement reports of different UEs that are transmitted to a first node (e.g., a roadside unit (RSU) or base station). The first node may configure a measurement procedure for multiple UEs that includes multiple measurement stages, in which a first stage provides that a subset of UEs transmit while other UEs measure received radar signals, and a second stage switches the transmitting and measuring UEs. Each of the UEs may provide measurement reports to the first node, which determines coordinated transmit parameters for the UEs to reduce interference among the UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit a request for a base station to establish a wireless communication link between the first UE and a second UE via an assisting device (AD) associated with an assisting node (AN). The first UE may receive first control signaling from the base station including an indication for the first UE to perform a directional learning procedure with the AN in response to the request, and may transmit an uplink message including an indication of a completion of the directional learning procedure. The first UE may receive second control signaling from the base station indicating a set of resources for performing a link configuration procedure between the first UE and the second UE, and may communicate with the second UE via the AD of the AN based on the second control signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device supports sidelink communications, including device-to-device (D2D) communications and vehicle-based communications. The communication device receives, from another device, a discontinuous transmission (DTX) configuration for a sidelink connection between the communications device and the other device. Based on the received DTX configuration, the communications device determines a discontinuous reception (DRX) configuration and transmit, to the other device, the determined DRX configuration. The devices experience power savings, among other results according to the DTX configuration or the DRX configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver user equipment (UE) may receive at least one control communication that includes a first part and a second part. The UE may determine an authenticity status of the at least one control communication based at least in part on at least one of a common security key corresponding to the first part or a private security key corresponding to the second part. The UE may perform a wireless communication task based at least in part on the authenticity status of the at least one control communication. Numerous other aspects are described.

Abstract: A configuration to allow a wireless device having one or more TRPs to configure the one or more TRPs based on configurations of other wireless devices. The apparatus detects a second wireless device in a vicinity of a first wireless device. The apparatus determines a duplex configuration of the second wireless device. The apparatus enables a duplex configuration of the first wireless device to correspond with the duplex configuration of the second wireless device. The apparatus communicates with the second wireless device based on the duplex configuration.

Abstract: Certain aspects of the present disclosure provide techniques for reconfigurable intelligent surface-based interference cancellation. A method that may be performed by a network entity generally includes determining to perform interference cancellation with a reconfigurable intelligent surface (RIS) for interference that will occur at a first wireless node based at least in part on one or more criteria, wherein the interference includes an interfering signal that will be transmitted by a second wireless node; and performing the interference cancellation with reflections from the RIS in response to the determination.

Abstract: Aspects presented herein may enable one or more wireless devices to perform a sidelink-based ranging and/or positioning with an assistance of an RIS. In one aspect, a first wireless device receives an information indicating at least a time in which at least one RIS is to be activated. The first wireless device transmits a first set of reference signals to a second wireless device via the at least one RIS. The first wireless receives a second set of reference signals transmitted from the second wireless device via the at least one RIS. The first wireless calculates a first signal RTT based on the first set of reference signals and the second set of reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. A target user equipment (UE) may receive an indication of a session key from an initiator UE in a sidelink communications system, from a network entity (e.g., a base station), or the like. In some cases, the target UE may also receive an indication of a nonce in a message of a PRS procedure. The target UE may select a positioning reference signal (PRS) sequence for the PRS procedure using the session key and optionally the nonce, such as by using a defined function at the target UE with the session key and the nonce as an input. Once the target UE selects the PRS sequence, the target UE may encode the PRS sequence and may transmit the PRS sequence to the initiator UE.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may generate a first encryption key and a second UE may generate a second encryption key based on a measurement of a channel between the first UE and the second UE. The second UE may transmit, to the first UE, a sidelink message including a one-way digital signature generated using the second encryption key and a message from a defined set of messages. The first UE may generate a set of one-digital signatures using the first encryption key and the defined set of messages and determine whether the one-way digital signature matches one of the set of one-way digital signatures. If there is a match, the first UE and the second UE may communicate using the encryption keys. Otherwise, the first UE and the second UE may generate new encryption keys.
