Method and device for coordinating cell interference between devices

Abstract

The embodiment of the present invention discloses a method and device for coordinating cell interference between devices, which relates to the communication field and can solve the problem that the base station cannot accurately know the signal quality of the D2D link when D2D communication is performed between terminals at the edge of the cell. The problem that inter-cell interference cannot be accurately reduced. The method of the present invention includes: when the first terminal becomes a detection terminal, the first terminal receives configuration information sent by the first base station, the configuration information includes resource usage detection parameters, and the resource usage detection parameters are used to configure the resource usage detection mode of the first terminal ; The first terminal detects the resource usage information of the resource location according to the resource usage detection parameter; the first terminal reports the resource usage information to the first base station, so that the first base station can provide the first terminal or the second terminal using the resource location according to the resource usage information Adjust the D2D data transmission mode.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for coordinating cell interference between devices. Background technique [0002] Device to Device (D2D) is an end-to-end direct communication technology, that is, the communication between terminals no longer needs the transfer of the base station, and the base station only needs to assist in resource configuration, scheduling, coordination, etc. Terminals communicate directly with each other. In order to enable terminals between adjacent cells to perform D2D communication, base stations need to exchange resource pool information, and the base station needs to broadcast the resource pool information of this cell and adjacent cells. According to the resource pool information broadcast by the base station, the terminal transmits or listens to signals in the corresponding resource pool, so as to have the opportunity to listen to the resource po...
