Method of transmitting signal and method of receiving signal
In a multicell communication system, a terminal that belongs to a second cell using the same subcarrier as a terminal that belongs to a first cell changes a pilot in an allocated basic resource block. Then, a base station that manages the first cell can estimate a channel of an interference signal transmitted from a second cell from a reception signal even though the reception signal includes an interference signal from the terminal that belongs to the second cell at the time of receiving a signal transmitted from the terminal that belongs to the first cell. Further, the base station that manages the first cell may reduce an interference signal from a reception signal by using a channel estimation value.
