  The research efforts on cellular vehicle-to-everything (V2X) communications
are gaining momentum with each passing year. It is considered as a
paradigm-altering approach to connect a large number of vehicles with minimal
cost of deployment and maintenance. This article aims to further push the
state-of-the-art of cellular V2X communications by providing an optimization
framework for wireless charging, power allocation, and resource block
assignment. Specifically, we design a network model where roadside objects use
wireless power from RF signals of electric vehicles for charging and
information processing. Moreover, due to the resource-constraint nature of
cellular V2X, the power allocation and resource block assignment are performed
to efficiently use the resources. The proposed optimization framework shows an
improvement in terms of the overall energy efficiency of the network when
compared with the baseline technique. The performance gains of the proposed
solution clearly demonstrate its feasibility and utility for cellular V2X
communications.
