Arrangement and technique for interference mitigation

摘要

In a telecommunications network. including a first cell with a first base station node having a first node controller component and a first radio network controller (RNC) component; a method of mitigating interference within the first cell including: the first base station node determining when the first cell is experiencing interference; and the first base station node determining which one or more adjacent cells is likely to be a source of the interference; and the first base station node initiating a command configured to effect a reduction in power used by the one or more adjacent cells. The determination of likely interference source may be by received total wideband power (RTWP) measurements or outer loop power control (OLPC) commands. Preferably the first base station node determines the likely source of interference via the user terminals within its cell which are currently in soft handover, in that the cell or cells that they are in soft handover with are likely to contain the source of the interference.
