Various systems and methods for establishing, configuring, and operating multi-access edge computing (MEC) communications, such as in connection with management of preferred channel allocations between two or more vehicle-to-everything (V2X) Radio Access Technologies (RATs), are discussed herein. In embodiments, a resource allocation (for example, channel allocations) for vehicle user equipment (vUEs) is determined based on a number of vUEs supporting each of one or more V2X RATs detected in one or more coverage areas of one or more Road Side Units (RSUs). Other embodiments are described and/or claimed.
