Abstract

The invention provides a method and device for resource sharing in device-to-device communication. The method comprises the following steps: one of a first group of D2D (Device to Device) communication devices exchanges first resource control information with another of the first group of the D2D communication devices in a control information sub-band of a first time domain, a data sub-band of the first time domain is used for transmitting data packets among a second group of D2D communication devices, and the first resource control information is used for dispatching data transmission of a data sub-band of a second time domain; one of the first group of the D2D communication devices sends or receives the data packets between the one and the another of the first group of the D2D communication devices in a data sub-band of the second time domain according to the first resource control information, and a control information sub-band of the second time domain is used for exchanging second resource control information among a third group of D2D communication devices. The method and the device, provided by the embodiment of the invention, can ensure adequate resource utilization rate.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a resource sharing method and device in Device to Device (Device to Device, D2D) communication. Background technique [0002] With the rapid increase of the number of people using wireless communication networks and the increasing requirements for the performance of wireless communication networks, the shortcoming of spectrum resources has become the key to limit the performance of wireless communication. At present, the cellular network is the main wireless communication network. In this communication network, the communication between two terminals needs to be forwarded by the base station. The same data packet travels from the terminal to the base station, and then from the base station to another terminal, occupying air interface resources twice. If the two terminals are far away and cannot reach each other directly, this solution is more feasible; but if the commu...
