A resource allocation method and roadside unit

Abstract

The embodiment of the present invention discloses a resource allocation method, including: the first roadside unit RSU receives the resource scheduling request sent by the first vehicle and the external V2X communication group; allocates communication resources for the first V2X communication group; wherein, The vehicles included in the first V2X communication group travel in the same direction. The embodiment of the invention also discloses a roadside unit. By adopting the present invention, the rationality of resource allocation can be improved, so that the communication link and channel quality between vehicles are relatively stable, and the performance of the Internet of Vehicles can be fully utilized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource allocation method and a roadside unit. Background technique [0002] The information exchange between vehicles and the outside world (Vehicle to X, referred to as V2X) is a key technology for future intelligent transportation systems. It enables communication between vehicles, vehicles and base stations, and vehicles and mobile devices. In order to obtain a series of traffic information such as real-time road conditions, road information, and pedestrian information, so as to improve driving safety, reduce congestion, and improve traffic efficiency. It may include vehicle-to-vehicle (Vehicle-to-Vehicle, V2V for short), vehicle-to-infrastructure (Vehicle-to-Infrastructure, V2I) information exchange, and vehicle-to-mobile device information exchange. Among them, V2V refers to a direct or indirect communication behavior between vehicles. There are two mai...
