A method for inter-frequency cooperative resource allocation in vehicle-to-everything (V2X) communication for short-range communication

Abstract

This application relates to the field of vehicle-to-everything (V2X) resource allocation technology, and particularly to a method for V2X inter-frequency cooperative resource allocation for short-range communication. The method includes: constructing a V2X system for wireless data transmission; the V2X system operating simultaneously in licensed and unlicensed frequency bands; constructing a coexistence model of heterogeneous V2X networks in the unlicensed frequency band; constructing a channel model of the V2X network in the licensed frequency band; constructing a resource allocation optimization problem with the objective of maximizing total V2V throughput; and decomposing the optimization problem into sub-problems for solving. Sub-problems include a first sub-problem of backoff window parameter optimization and a second sub-problem of power and resource allocation. The method designed in this application addresses the difficulty in resource allocation caused by the limited resources in licensed frequency bands and the difficulty in coexisting heterogeneous networks in unlicensed frequency bands.
