Abstract
Embodiments of the present application disclose a device-to-device (D2D) communication method, a method for assigning a D2D communication resource, and apparatuses thereof. The D2D communication method comprises: determining a usable resource in a D2D communication resource; and sending scheduling assignment (SA) information correlated to at least one D2D device by using a first control channel resource in a D2D control channel resource, wherein the first control channel resource is only used to transmit control information correlated to first-type D2D communication, and a first physical parameter configuration of the first control channel resource is different from a physical parameter configuration of another control channel resource in the D2D control channel resource. For the methods and apparatuses in the embodiments of the present application, a control channel resource independent of other D2D communication is used, so that at the same time when transmission quality of specific-type D2D communication is improved, use efficiency as the specific-type D2D communication and other D2D communication coexist on a spectrum resource is improved.
