Abstract

The invention provides a D2D communication method and device on an unauthorized frequency band, a terminal and a base station. The method comprises the steps of receiving granularity information, indicated by the base station and adopted for D2D communication on the unauthorized frequency band, of a spectrum resource; judging whether there are D2D data on the unauthorized frequency band needing to be transmitted; acquiring a transmission resource for D2D communication on the unauthorized frequency band if yes according to the granularity information indicated by the base station; transmitting the D2D data on the unauthorized frequency band based on the acquired transmission resource. By the adoption of the technical scheme, application of a D2D communication mechanism on the unauthorized frequency band can be achieved, and operation of D2D communication on the unauthorized frequency band is achieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a D2D communication method on an unlicensed frequency band, a D2D communication device on an unlicensed frequency band, a terminal and a base station. Background technique [0002] D2D (Device-to-Device, device-to-device) communication is a technology for direct communication between terminals introduced by 3GPP Release-12, which introduces a secondary link ( sidelink) concept. The D2D communication technology has completed the standardization of 3GPP Rel-12 and Rel-13, and the 3GPP is currently standardizing Rel-14. D2D communication technology is mainly aimed at public security scenarios in Release 12 and Rel-13, and is standardized for commercial scenarios starting from Rel-14. In addition, D2D technologies from Rel-12 to Rel-14 are mainly aimed at licensed frequency bands, base station control signaling related to D2D communication, synchronization signals b...
