Abstract: A user equipment (UE) in a vehicle (V-UE) broadcasts multi-phased ranging signals with which other entities may determine the range to the V-UE. The multi-phased ranging signals may include a first message, which may be broadcast in the Intelligent Transport System (ITS) spectrum, includes ranging information, such as a source identifier, location information for the broadcasting V-UE, and an expected time of broadcast of the ranging signal. The ranging signal may then be broadcast at the expected time and may include the source identifier. A second message, which be broadcast in the ITS spectrum, may include clock error information for the V-UE. A receiving entity may determine the range to the V-UE based on the time of arrival of the ranging signal and the expected time of transmission, as well as the clock error information. The receiving entity may further generate a position estimate based on the received location information.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive an indication of one or more parameters for communications over a sidelink channel during a first time period, where the one or more parameters may include a time threshold for a second resource pool. The wireless device may transmit data over a first resource pool of the sidelink channel during a first portion of the first time period based on the one or more parameters, the first resource pool including resources for communications between the first wireless device and a second wireless device. The wireless device may monitor the second resource pool during a second portion of the first time period for the time threshold, the second resource pool including resources for communications between the first wireless device and a third wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) in a wireless communications system, such as a vehicle-to-everything (V2X) communications systems, may communicate over sidelink to other UEs. The first UE may receive, from a base station, control signaling indicating a sidelink resource pool allocated for sidelink communication between the first UE and a second UE. The first UE may transmit an indication that superposition coding may be used to generate a concurrent sidelink and uplink transmission. The first UE may then transmit the concurrent sidelink and uplink transmission within a resource of the sidelink resource pool based on the indication. The second UE may decode the sidelink portion of the transmission, and the base station may decode the uplink portion of the transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a first and second directional beam for communicating with one or more UEs on a first and second sidelink communication link. In some cases, the UE may identify a first sidelink feedback configuration for the first directional beam. The UE may also identify a second sidelink feedback configuration for the second directional beam, where the second sidelink configuration may be different from the first sidelink feedback configuration. In some examples, the UE may transmit an indication of the first sidelink feedback configuration and the second sidelink feedback configuration to the one or more UEs, where received feedback for sidelink messages sent over the directional beams may be based on the different sidelink feedback configurations. In addition, feedback resources may be based on a beam identifier of a beam used to transmit an initial sidelink message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a network node, an indication of first level shared information, that is shared between at least the first UE and a second UE, for deriving a security key from common sidelink information. The first UE may determine second level shared information, that is shared between the first UE and the second UE, for deriving the security key from the common sidelink information. The first UE may communicate with the second UE using the security key derived from the common sidelink information based at least in part on the first level shared information and the second level shared information. Numerous other aspects are described.

Abstract: Aspects presented herein may enable a first UE to utilize inference results provided by at least a second UE to improve its inference accuracy. In one aspect, a first UE establishes an ML inference result sharing session with one or more second UEs for at least one ML inference task. The first UE receives a first set of ML inference results associated with the at least one ML inference task, where the first set of ML inference results is received from the one or more second UEs during the ML inference result sharing session. The first UE estimates an aggregated ML inference result based on at least one of the first set of ML inference results or a second set of ML inference results, where the second set of ML inference results is configured by the first UE for the at least one ML inference task.

Abstract: Method and apparatus for on demand assistance for sidelink communication. The apparatus receives, from a base station, an AN configuration for one or more ANs associated with the base station. The apparatus transmits, to the base station, an AR to request assistance with communication with a second UE from at least one AN associated with the base station. The apparatus receives, from the base station, a grant to schedule sidelink transmission with the second UE. The sidelink transmission with the second UE is assisted by at least one AN of the one or more ANs associated with the base station.

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.

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.
