Title: SIGNAL SENDING METHOD, RECEIVING METHOD, APPARATUS AND COMMUNICATION DEVICE
Abstract:
Disclosed are a signal sending method, a receiving method, an apparatus and a communication device used for device to device communication. The methods comprise: a first communication device determining a sending time of a first subframe and a subframe structure of the first subframe, wherein: the first subframe comprises a protection interval and the subframe structure of the first subframe comprises a length of the protection interval and a position of the protection interval in the first subframe, or the first subframe comprises a data signal and the subframe structure of the first subframe comprises a length of the data signal and a position of the data signal in the first subframe; and the first communication device sending the first subframe to a second communication device based on the subframe structure of the first subframe at the sending time of the first subframe. In such a manner, resources can be properly utilized without reducing system transmission efficiency, and an adaptive range is wide.
