Problems solved by technology

[0003] In the resource allocation method of D2D communication based on base station scheduling, the base station first sends a sidelink control information (SCI) to the data sender in D2D communication, and then the data sender sends the SCI to the receipt receiver end, repeated SCI transmission introduces a lot of additional signaling overhead and scheduling delay, reducing the efficiency of D2D communication

Abstract

Provided are a device-to-device communication method and a communication device, the method comprising the steps: a first node generating scheduling information, the scheduling information being usedfor scheduling transmission between a second node and a third node, the scheduling information comprising resource indication information and behavior indication information, wherein the resource indication information is used for indicating resources used for transmission between the second node and the third node, and the behavior indication information is used for indicating a sender and / or a receiver when the second node and the third node perform transmission on the resources; and the first node sends the scheduling information to the second node and the third node. The communication method provided by the invention can be applied to one or more of D2D communication, M2M communication, MTC communication, V2X communication in an Internet of Vehicles system and the like, and can save signaling overhead and can improve D2D communication efficiency during resource allocation of D2D communication.

Description

technical field [0001] The present application relates to the field of wireless communication technologies, and in particular to a device-to-device communication method and a communication device. Background technique [0002] The device-to-device (D2D) communication technology can realize the communication between short-distance terminals directly through the side link (sidelink) without the transfer of the base station. Compared with the traditional cellular system communication mode, this communication mode , can effectively reduce the transmission delay, and is suitable for high-speed data stream transmission, and the introduction of D2D communication in the cellular network can reduce the burden on the base station. D2D communication can work in the licensed frequency band and is still controlled by the base station. It can be adaptively configured or scheduled according to the scene. By reusing the spectrum of cellular users, it can improve spectrum efficiency, improve...
