Abstract

The invention relates to an interference control method and device. The interference control method comprises the following steps: executing adjacent area measurement, and selecting at least one adjacent area whose signal sending intensity is larger than the signal sending intensity of a service cell in measured adjacent areas as an interference cell; analyzing a physical broadcast channel PBCH of the interference cell to obtain an antenna port number of the interference cell; obtaining a cell reference signaling CRS position of the interference cell according to a physical cell identifier PCI and the antenna port number of the interference cell; and carrying out interference control according to the CRS position information. According to the interference control method provided by the embodiment of the invention, the interference of adjacent area signals to user equipment in the service cell is weakened, and thus the call quality of the user equipment in the service cell is improved; and some hotspot cells better share the business burden of a macro cell.

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. The technical background of the present invention will be described below by taking a Long Term Evolution (LTE for short) and / or Long Term Evo...
