Resource allocation method and device

Abstract

The invention discloses a resource allocation method and device which can be applied to the automatic driving or the field of automatic driving, and particularly relates to short-distance communication of a cockpit domain. The method comprises determining a first time-frequency resource for at least one second device; determining a target time-frequency resource for the at least one second device; sending the first information, wherein the first information is used for indicating at least one of the first time domain resource offset and the first frequency domain resource offset, wherein the first time domain resource offset is the offset of the first time frequency resource and the target time frequency resource on the time domain; and / or the first frequency domain resource offset is the offset of the first time frequency resource and the target time frequency resource in the frequency domain. According to the embodiment of the invention, the method can achieve the quick configuration of the time-frequency resources, and improves the configuration efficiency of the resources.

Description

technical field [0001] This application relates to the field of smart cockpit technology, and provides a resource configuration method and device. The present application further relates to the technical field of short-distance communication. Background technique [0002] With the continuous development of autonomous driving technology and smart cockpit technology, the driving tasks of future vehicles can be replaced by machines. Smart cockpit technology provides a richer audio-visual entertainment experience and office experience in the car environment, and vehicles are no longer just transportation tools. Or the means of transportation is one of the spaces in which people live. [0003] At present, the equipment involved in the smart cockpit includes the cockpit domain controller (CDC, Control Domain Cockpit), vehicle-mounted audio equipment (such as stereos, microphones, etc.), in order to avoid complicated wiring in the small car and reduce costs, the vehicle and machin...

AI Technical Summary

Problems solved by technology

In areas with dense vehicles, such as short-distance communication scenarios, such as traffic light intersections and high-speed service areas, it is easy for the time-frequency resources used by multiple vehicles to overlap or conflict, resulting in interference in corresponding communications

This kind of interference will lead to failure of vehicle wireless audio signal transmission, packet loss, failure of noise cancellation function, distortion of audio played by speakers, etc., seriously affecting the experience of passengers in the car

Even, it may lead to failure or failure of signal transmission related to driving safety, endangering driving safety
