Problems solved by technology

However, the small cell does not know the resources allocated by the macro cell for D2D communication, so small cell communication and D2D communication will cause mutual interference

Embodiment Construction

[0057] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. 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.

[0058] Such as figure 1 As shown, the heterogeneous network includes a macro base station 11, a small base station 12, and three terminals.

[0059] In the embodiment of the present invention, the macro base station may refer to an evolved base station (evolved NodeB, eNB); the small base station may refer to a femto base station (Femtocell)...

Abstract

Provided are a method and device for reducing interference. The method comprises a macrocell determining a first time-frequency resource information, said information being the resource allocated by said macrocell for D2D communication; the macrocell sends said first time-frequency resource information to a small cell, allowing said small cell, on the basis of said information, to prohibit the scheduling on said resource of terminals engaging in cellular communication. By means of embodiments of the present invention, interference between small cell communication and D2D communication can be reduced.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method and equipment for reducing interference. Background technique [0002] In cellular network communication, the communication between two terminals needs to be forwarded by the base station. The same data packet occupies the air interface resources twice from the terminal to the base station, and then from the base station to the terminal. If the two communication terminals are far away and cannot reach each other, this solution is more feasible. However, if the communication parties are relatively close to each other, direct communication (Device to Device, D2D) between terminals can be used to save resources. D2D communication enables direct communication between terminal devices without any intermediary infrastructure. [0003] Some traditional technologies can realize D2D communication, for example, wifi, BT, and ad hoc. However, these systems all work in an async...
