A sidelink resource load measurement method and device in a v2x network

Abstract

The invention discloses a resource load measurement method of sidelink in a V2X network and an apparatus thereof. The method comprises the following steps of receiving resource set information sent bya base station to user equipment of some positions based on position information reported by the user equipment so that the user equipment monitors information carried by each PSCCH channel in an assigned time frequency resource set according to the resource set information, and acquiring a monitoring result; according to the monitoring result, calculating and acquiring a first frequency of a multi-user PSSCH channel resource conflict and a second frequency of a multi-user PSCCH channel resource conflict corresponding to each resource pool in the time frequency resource set in a preset period; processing the first frequency and the second frequency and acquiring a data conflict frequency and a scheduling distribution conflict frequency corresponding to each resource pool in the time frequency resource set; and when the data conflict frequency or the scheduling distribution conflict frequency is determined to be greater than or equal to a preset first threshold, sending the data conflict frequency or the scheduling distribution conflict frequency to the base station so that the base station acquires resource load information of each resource pool.

Description

technical field [0001] The present invention relates to the field of V2X, in particular to a method and device for measuring sidelink resource load in a V2X network. Background technique [0002] V2X (Vehicle to X, information exchange between vehicles and the outside world) is a key technology for future intelligent transportation systems. V2X was approved as a project at the 3GPP RAN#68 meeting, mainly researching the vehicle data transmission scheme based on the 3GPP communication protocol. V2X communication includes V2V communication (Vehicle to Vehicle, vehicle-to-vehicle communication), V2I communication (Vehicle to Infrastructure, vehicle-to-roadside infrastructure communication) and V2P communication (Vehicle to People, 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. [0003] There are two resource schedulin...

AI Technical Summary

Problems solved by technology

However, at present, the network side cannot know the resource load information of the resource pool in the UE autonomous resource selection mode, and thus cannot know the resource conflict situation between users.

Furthermore, the reliable transmission of V2X services cannot be effectively guaranteed according to resource load information, and it is not conducive to improving resource utilization
