Abstract

The invention discloses a method for predicting a quality of service for a communication, an apparatus, a vehicle and a backend server. The proposal introduces the idea of the creation of a link-basedQoS map. In one embodiment the proposal concerns a method for predicting a quality of service for a communication between at least two moving communication partners (PL, PV1 - PV4), wherein the prediction is based on at least one link-based quality of service map, that is updated in a link-based QoS map generation process. Since classical radio maps are node-based, they are not appropriate for estimating an end-to-end latency for the communication link. The end-to-end latency however is needed when it comes to the question if safety critical messages can be exchanged over this communication link. The proposal can be used advantageously in a high density platooning application for cooperative driving. In this application a drop in the communication performance, in particular in an end-to-end latency, would affect its safe running. With the solution according to the proposal it is however possible to adapt the inter vehicle distance (d) in dependence of the prediction of the link-basedQoS.

Description

technical field [0001] The present disclosure relates to a method for predicting the quality of service of a communication between at least two dynamically moving communication partners. The proposal also discloses a corresponding device, a vehicle, a background server and a corresponding computer program for carrying out the steps of the method. Background technique [0002] For the scenario of vehicles equipped with wireless communication modules providing connectivity to public communication networks but also direct communication capabilities for exchanging information among road participants, wireless communication offers the opportunity to achieve a wide range of applications. Much research has been done in the areas of cooperative and autonomous driving. Direct communication between vehicles is often referred to as vehicle-to-vehicle communication (V2V). Also possible is communication from and to vehicles utilizing infrastructure communication stations such as roadsi...
