1. A method of frequency-offset determination, performed by a first device in a new radio (NR) vehicle-to-everything (V2X) network communicating on a high-frequency carrier, the method comprising:
receiving a resource block containing one or more auxiliary frequency-offset estimation signals and pilot signals from a second device; and
calculating the one or more auxiliary frequency-offset estimation signals and the pilot signals to determine a frequency offset for demodulating the resource block, wherein at least one of the first device or the second device is a vehicle.
