Method and device for consulting resource in D2D (Device To Device) communication

Abstract

The embodiment of the invention discloses a method and a device for consulting resource in D2D (Device To Device) communication. The method comprises the steps that: a current device receives resource demand information sent by the other device in a current super frame, and the resource demand information comprises a service priority level of the other device, a beacon time slot of a beacon of the other device and / or the amount of resource applied by the other device; and the resource position which can be distributed for the current device can be calculated according to the service priority level of the other device, the beacon time slot of the beacon of the other device and / or the amount of the resource applied by the other device by the current device. By adopting the method or the device disclosed by the embodiment of the invention, the phenomenon that the same resource is competed by multiple devices is avoided, and the efficiency of consulting the resource between the devices is increased.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a resource negotiation method and device in D2D communication. Background technique [0002] The Internet of Things refers to the acquisition of information in the physical world by deploying various devices with certain perception, calculation, execution and communication capabilities, and realizes information transmission, collaboration and processing through the network, thereby realizing the interconnection between people and things, and things and things. network of. In short, the Internet of Things is to realize the interconnection between people and things, things and things. The application of the Internet of Things includes various aspects such as smart grid, smart agriculture, smart transportation, and environmental detection. D2D (Device-to-Device, device-to-device) communication, as a kind of Internet of Things application, mainly realizes direc...

Problems solved by technology

[0005] Because the device does not consider the available resources for sending beacon frames when performing discovery, and sends beacon frames arbitrarily on existing cellular communication resources, which will cause interference to existing cellular communications, even if the device can achieve discovery , but it is also impossible to know the resource reservation between each other, which will cause the devices to compete for resource occupancy after discovery, or perform a complicated negotiation process for reserved resources, and the efficiency is low when directly applied to the cellular communication environment; Furthermore, if the beacon frame contains reservation information directly related to a certain MAS, then there may be resource reservation conflicts, and a complicated conflict handling process is required, which will also lead to relatively inefficient resource negotiation between devices. lower
