Document Type and Number:
Japanese Patent JP6440720
Kind Code:
B2
Abstract:
Disclosed are a D2D communication method and device. The method comprises: transmitting, by a transmitting-end device, a control message in a control region of a current communication frame, the control message at least comprising resource indication information, and monitoring control messages, at least comprising the resource indication information, of other transmitting-end devices in the control region of the current communication frame, the resource indication information being used for indicating a data channel in a data region of the current communication frame occupied by the transmitting-end device; and according to the monitored resource indication information, transmitting D2D data on the data channel occupied thereby. In the technical solution provided in the embodiments of the present invention, the communication frame for D2D communications comprises a control region and a data region, wherein the data region further comprises a plurality of data channels. By way of mutually monitoring a control message of a control region by different transmitting-end devices, the resource conflict caused by competition can be avoided.
