Abstract: Methods, systems, and devices for ranging are described. A multi-phase distributed ranging technique includes transmitting and receiving vehicle information messages during a first time interval, where the vehicle information messages include at least a vehicle identifier and resource information. The multi-phase technique further includes transmitting and receiving ranging signals during a second time interval, and determining times of arrival of received ranging signals. A centralized ranging technique includes receiving resource assignments from an access point, transmitting ranging signals according to the resource assignments, and determining times of arrival of received ranging signals.

Abstract: Methods, systems, and devices for wireless communications are described that improve privacy in wireless communications, such as communications by a user equipment (UE), which may in some cases be a vehicle UE. For example, various vehicle-to-everything (V2X) transmissions may be unencrypted, and a vehicle may be expected to periodically change one or more identifiers it uses for various communication services. Privacy may be enhanced, for example, via encryption key roll-over, as well as roll-over of one or more other identifiers associated with a UE that may potentially be used by an observer to track the UE. The UE may transmit a message that includes an updated lower layer identifier (e.g., a layer-2 (L2) identifier) to another UE in a V2X unicast communications link, which may trigger a change in identifiers of a set of identifiers and an updated security context. All or a portion of the message may be encrypted.

Abstract: Certain aspects of the present disclosure provide techniques relating to wireless communications between vehicles. In certain aspects, a method performed by a first vehicle comprises receiving an indication from a second vehicle comprising surrounding information that is indicative of whether a first unknown vehicle is detected by the second vehicle, wherein the first vehicle and the second vehicle are able to communicate wirelessly, and wherein the first unknown vehicle is unable to communicate wirelessly with the first and the second vehicles. The method further comprises controlling movement of the first vehicle based on the indication.

Abstract: Aspects of the present disclosure describe indicating per-packet quality of service (QoS) in communications by a wireless communications device. A packet from an application generated for a first radio access technology (RAT) can be obtained, where the packet includes a first QoS value associated with the first RAT, and/or the first QoS value can be mapped to a second QoS value associated with the second RAT. In another example, the QoS value can be indicated in the packet along with a reflective indicator indicating to use the QoS value in transmitting a response to the packet.

Abstract: Methods, devices, non-transitory processor-readable media of various embodiments provide for routing Misbehavior Detection Reports from vehicle-to-everything (V2X) onboard equipment to an associated entity. Various embodiments may include storing, within a Misbehavior Report Router resulting from provisioning of a certificate to a V2X onboard equipment, information that enables a Misbehavior Detection Report to be routed to the entity associated with misbehaving V2X onboard equipment, examining a Misbehavior Detection Report received from a reporting V2X onboard equipment to identify a Pseudonym Certificate Authority Misbehavior Report Router of the entity associated with misbehaving V2X onboard equipment, passing the Misbehavior Detection Report to the identified Pseudonym Certificate Authority Misbehavior Report Router, using information in the Misbehavior Detection Report with information stored in the Pseudonym Certificate Authority Misbehavior Report Router to route the Misbehavior Detection Report to the associated entity.

Abstract: Methods, systems, and devices are described for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a wireless relay requirement associated with the first wireless device. A proximity service protocol may be initiated between the first wireless device and a second wireless device based at least in part on the identified wireless relay requirement. The proximity service protocol may be initiated prior to an initiation of a communication data exchange between the first wireless device and the second wireless device. A relay link may be established, via the ProSe protocol, between the first wireless device and the second wireless device based at least in part on the identified wireless relay requirement.

Abstract: Aspects of the disclosure relate to a system, method, and device for establishing a secure link for wireless communication. A device may send a service announcement message to at least one other device via sidelink signaling. The service announcement message indicates a capability of the device to perform a service and includes at least a security certificate of the device. The device establishes a secure link with the at least one other device corresponding to the service by establishing a device key between the device and the at least one other device. The device then communicates service data for the service between the device and the at least one other device via the secure link based on the established device key. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices are describe for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a group identity parameter associated with a multicast transmission of multimedia content. The first wireless device may map the identified group identity parameter to an identification parameter associated with at least one proximity service (ProSe) relay wireless device. The first wireless device may receive the multicast transmission of the multimedia content via the at least one ProSe relay wireless device based on the mapping of the identified group identity parameter to the identification parameter.
