Problems solved by technology

In this way, if the existing D2D technology is used, eNB and UE do not confirm the scheduling of PC5 port resources, which will cause waste or conflict of PC5 port resources, and may even greatly increase the transmission delay of V2X services

Abstract

The invention provides a confirmation method of scheduling PC5 port resource in V2X network, comprising the steps that a base station eNB sends the control command of Sidelink SPS resource to a user device UE through PDCCH; after the UE receives the control command, the UE sends ACK feedback information to the eNB through physical upstream link control channel, enabling the eNB to confirm based onthe ACK feedback information. The invention is advantageous in that the reliability of the Sidelink SPS resource control command (including activating command / releasing command) can be enhanced; theinterference to the upstream channel and Sidelink can be reduced; the periodic PC5 port resource can be distributed to the UE timely, and thereby V2X business data can be sent out timely at the PC5 port.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for confirming scheduling PC5 port resources in a V2X network. Background technique [0002] V2X (Vehicle to X), that is, the information exchange between the vehicle and the outside world, is the key technology of the future intelligent transportation system. The main research of V2X is based on the vehicle data transmission scheme of the third generation partnership project (3rd Generation Partnership Project, referred to as 3GPP) communication protocol. V2X communication includes V2V communication (vehicle-to-vehicle communication), V2I communication (vehicle-to-roadside infrastructure communication) and V2P communication (vehicle-to-pedestrian communication). V2X applications will improve driving safety, reduce congestion and vehicle energy consumption, improve traffic efficiency and in-vehicle entertainment information, etc. Most of the V2X services...
