Abstract:
Methods, systems, and devices for wireless communications are described. The method may include an interference estimation procedure that measures interference from radio access technologies (RATs) different from cellular vehicle to everything (CV2X) on the CV2X network at a user equipment (UE). A UE may record measurements of interference on the CV2X network when no CV2X signal is present during the last symbol of a subframe. Then, the UE may estimate the noise plus interference measured during the empty symbol to improve noise plus interference whitening when decoding a subframe.
