Problems solved by technology

In the case of strong interference at the edge of the cell, the CRS signaling of the ABS subframe of the neighboring cell will still affect the downlink Physical Downlink Control Channel (PDCCH) and Physical Downlink Shared Channel of the UE in the interfered cell. (Physical Downlink Share Channel, referred to as PDSCH) signaling / data decoding poses a great threat

Abstract

The invention relates to an interference control method and equipment. The interference control method comprises the steps of: executing measurement of adjacent cells, and selecting at least one adjacent cell, with signal transmission intensity more than that of a serving cell, among the measured adjacent cells to serve as an interference cell; analyzing a physical broadcast channel (PBCH) of the interference cell, and acquiring the number of antenna ports of the interference cell; acquiring the position of a cell reference singaling (CRS) of the interference cell according to the a physical cell identifier (PCI) and the number of the antenna ports, of the interference cell; and carrying out interference control according to the position information of the CRS. According to the embodiment of the invention, the interference of signals from the adjacent cells to user equipment in the serving cell are reduced, and the communication quality of the user equipment in the servign cell is improved; and furthermore, certain hotspot cells are enabled to well share service loads for a macrocell.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication, and more specifically, to an interference control method and device in a wireless communication system. Background technique [0002] The wireless communication system can provide wireless services such as voice and data. A general wireless communication system is a multiple access wireless system. In a wireless communication system, a base station transmits data and / or control information to a user equipment on a downlink, and receives data and / or control information from a user equipment on an uplink. Similarly, user equipment (User Equipment, UE for short) transmits data and / or control information for the base station on the uplink, and receives data and / or control information transmitted by the base station on the downlink. Hereinafter, the technical background of the present invention will be described by taking a Long Term Evolution (LTE for short) and / or Long T...
