METHOD AND APPARATUS FOR A REFERENCE SIGNAL IN A WIRELESS COMMUNICATION SYSTEM, CAPABLE OF IMPROVING CHANNEL ESTIMATION PERFORMANCE BY REDUCING THE COLLISION BETWEEN REFERENCE SIGNALS

摘要

PURPOSE: A method and apparatus for a reference signal in a wireless communication system are provided to improve the performance of measuring the position of a terminal by minimizing the collision between reference signals from each cell.;CONSTITUTION: A first base station transmits a first reference signal to a terminal by mapping the first reference signal to a resource area. A second base station transmits a second reference signal to the terminal by mapping a second reference signal to the resource area. The resource elements in the mapped resource area are determined in the index of an NXN Latin square matrix.;COPYRIGHT KIPO 2011
