Method for allocating resources in V2X network, and terminal

Abstract

The invention relates to a method for allocating resources in V2X network, and a terminal. The method comprises the steps that the terminal reports service periodic attribute information to a base station, so that the base station allocates the resources to the terminal by adopting a semi-persistent scheduling method according to the service periodic attribute information, wherein the terminal carries the service periodic attribute information by utilizing a control unit of a media access control layer that transmits a feature report or extends a sidelink buffer status report. According to the method for allocating the resources in the V2X network and the terminal, the terminal carries the service periodic attribute information by utilizing the control unit of the media access control layer that transmits the feature report, so that the base station can learn whether the service of the UE has periodicity and a corresponding periodic interval, therefore, the base station can adopt the semi-persistent scheduling method for allocating resources on a PC 5 interface to the UE according to the periodic interval reported by the UE, the overhead of a control channel is greatly saved, and the transmission delay of the periodic service is reduced indirectly.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a resource allocation method and a terminal 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. 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 communication), V2I communication (vehicle-to-roadside infrastructure communication) and V2P communication (vehicle-to-pedestrian communication). The application of V2X will improve driving safety, reduce congestion and vehicle energy consumption, improve traffic efficiency and in-vehicle entertainment information, etc. [0003] The basic message types of V2X are divided into cooperati...

AI Technical Summary

Problems solved by technology

However, in the current 3GPP protocol, the UE reports the cycle interval information of the periodic service, so the base station cannot use an appropriate scheduling method to allocate resources for the UE according to the service cycle attribute of the UE, so there is a lot of unnecessary control resource overhead
