    Abstract: The disclosure relates to systems, methods, and devices for protecting Vehicle-to-Everything (V2X) communications (also known as intelligent transport systems (ITS) communications) from spurious emissions of nearby wireless devices operating in near-band or adjacent frequency bands. The system detects radio signals of a nearby ITS communication device, determines its radio communication parameters, and determines an interference condition based on whether the wireless device may interfere with the ITS communication device. The system also requests a change, based on the interference condition, in the radio subsystem communication parameters of the wireless device. The system also determines a geographic location of the wireless device, and, based on whether the requested change complies with a regulatory requirement of the determined geographic location, implements the requested change.

    Abstract: The present disclosure provides technologies and techniques for power optimization of vulnerable road user (VRU) devices in Intelligent Transportation Systems (ITS)/Vehicle-to-Everything (V2X) systems/networks, Internet of Things (IoT) devices, and/or other small form-factor devices. The power optimizations involve disabling or placing the communications functionality of a device in a sleep or inactive mode in situations where such functionality is not needed. The power optimization techniques include medium access control (MAC) optimized discontinuous reception (DRX) configurations, location-based communication, wake-up signaling communication, contextual activation and parameterization of device communication, slot reservation communication. Additional aspects of devices and communication configurations and arrangements may be described.
