Contribution

It analyzes the feasibility of sharing the 4.9 GHz band between incumbent systems and V2X users, proposing a new spectrum sharing approach.

Findings

Shared spectrum can support V2X communication effectively.

Proposed sharing scheme reduces interference with incumbent systems.

Feasibility depends on specific spectrum management strategies.

Abstract

There is an unprecedented impetus on the advancement of internet of vehicles (IoV). The vehicle-to-everything (V2X) communication is well acknowledged as the key technology in constitution of the IoV. Nevertheless, the spectrum for V2X communication is undergoing a massive change in the United States: a majority of the bandwidth has been reallocated to Wi-Fi leaving even less than a half of the bandwidth for V2X. This motivates investigation of other candidate spectrum bands for operation of V2X communication as an urgent effort to guarantee efficient operations of IoV. To this line, this paper studies the feasibility of sharing the 4.9 GHz public safety band between the incumbent systems and V2X users.
