Abstract

The invention discloses a method and a device for determining data feedback resources, which are used for solving the problem of poor data transmission reliability in the existing Internet of Vehicles technology. The method comprises the steps that a first terminal receives first data sent by a second terminal; feedback resources of the first data are determined; wherein the feedback resources of the first data is one feedback resource in a feedback resources pool; and the feedback information of the first data is sent to the second terminal on the feedback resources, and the feedback information is used for indicating the receiving state of the first data, so that the second terminal of the sending end can determine whether the sent first data is successfully received or not by detecting the feedback information, and the reliability of data transmission is improved.

Description

technical field [0001] The present application relates to the field of wireless communication technologies, and in particular to a method and device for determining data feedback resources. Background technique [0002] The vehicle networking system aims to achieve the purpose of improving road safety, improving traffic efficiency and providing users with rich streaming media services through communication between vehicles and other devices (Vehicle to Everything, V2X), wherein the other devices include vehicles, Handheld terminal, roadside unit (RSU, Road Side Unit), and network, etc., the communication between the vehicle and other devices includes vehicle to vehicle (Vehicle to Vehicle, V2V), vehicle and pedestrian (Vehicle to Pedestrian, V2P), Vehicle to Network (V2N), etc., V2V, V2P, and V2I are collectively referred to as V2X. [0003] At present, cellular communication adopts technologies such as 2G / 3G / 4G. The Long Term Evolution (LTE) technology adopted in the 4G sy...
