Abstract
An apparatus, such as a user equipment or a vehicle, may receive a signal associated with vehicle-to-everything (V2X) communication. The apparatus may determine a total energy that corresponds to the received signal, such as by measuring the energy on one or more resources. The apparatus may determine a fractional energy associated with a first technology of the total energy, such as by detecting a sequence associated with a first technology included in the received signal and determining the energy with which the detected sequence is received. The apparatus may determine presence of a second technology based on the determined fractional energy.

A method of wireless communication, comprising:
- receiving a signal associated with vehicle-to-everything (V2X) communication;
- determining a total energy that corresponds to the received signal;
- determining a fractional energy of the total energy based on a sequence of known length included in the received signal, the sequence associated with a first technology;
- determining presence of a second technology when the determined fractional energy of the total energy fails to satisfy a threshold, wherein the determined fractional energy of the total energy fails to satisfy the threshold when the determined fractional energy is less than the threshold, wherein the second technology is dominant relative to or interferes with the first technology;
- and
- switching to the second technology for communication based on the determined presence of the second technology.
