Embodiment Construction
[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of them. . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] Such as figure 1 As shown, a schematic diagram of a D2D communication architecture involving a cellular network provided by an embodiment of the present invention. figure 2 Include two link types:
[0024] -D2N (Device to Network, device to network) link: a link for communication between the D2D terminal and the base station (eNodeB, evolved node B) of the cellular network;
[0025] -D2D link: a link for direct communication bet...

The invention provides a D2D resource allocation method and a device thereof. The D2D resource allocation method comprises the steps of determining a first D2D terminal set with D2D resource conflict and a base station to which terminals in the first D2D terminal set belong by a first base station; determining whether the first D2D terminal set comprises a terminal which belongs to a second base station by the first base station; and if yes, instructing the second base station to which the terminal in the first D2D terminal set belongs to re-allocate the D2D resource to the terminal that is in a second base station coverage area and belongs to the first D2D terminal set by the first base station, wherein the second base station is different from the first base station. The D2D resource allocation method and the device thereof are a settlement solution on the condition of detecting a fact that the base station with the D2D resource conflict is not same with the base station to which the terminal with the D2D resource conflict belongs. The D2D resource allocation method and the device thereof can perform resource reallocation through instructing the related base station, thereby reducing probability of the D2D resource conflict.
Description
technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to a D2D (Device to Device, device to device, also translated as D2D terminal direct connection) resource allocation method and device. Background technique [0002] The traditional cellular communication technology adopts the method of centralized network control. The terminal sends and receives data under the control of the network. The system network allocates wireless resources and transmits data through the network. In order to improve the transmission efficiency between terminals, a technology of direct communication between terminals, that is, a D2D technology, is currently proposed. When the distance between the terminals is very close, the D2D communication mode can be used to realize the interaction, and at this time, the D2D terminals do not need to interact with services such as voice and data through the base station. [0003] The D2D commun...
