METHOD AND A DEVICE FOR TRANSMITTING A REFERENCE SIGNAL TO CANCEL INTERFERENCE BETWEEN CELLS IN A MIMO COMMUNICATION SYSTEM, CAPABLE OF AVOIDING INTERFERENCE BETWEEN CELLS

摘要

PURPOSE: A method and a device for transmitting a reference signal to cancel interference between cells in a MIMO communication system are provided to prevent channel estimation and data transfer rates when a base station supports transmission antennas.;CONSTITUTION: A base station repetitively allocates a channel measurement reference signal by an antenna at a fixed frequency resource element interval after nulling or puncturing resource elements overlapped with resource elements to which a channel measurement reference signal of an adjacent cell is applied. The base station allocates a data signal to a residual resource element. The base station transfers location information of the channel measurement reference signal-allocated resource element to a terminal. The base station transmits a data packet.;COPYRIGHT KIPO 2011
