Abstract: Disclosed is a wireless communication system using multiple transmission and reception points. In a wireless communication system having a first transmission and reception point and at least one second transmission and reception point belonging to the same cell, the first transmission and reception point has a wider transmission area than the at least one second transmission and reception point, and the first transmission and reception point and the at least one second transmission and reception point generate downlink transmission signals by using the same physical layer cell ID or virtual cell IDs allocated to each terminal, and then the terminals generate uplink transmission signals by using the allocated virtual cell IDs.

Abstract: Disclosed is a pilot signal transmitting/receiving device and method in a wireless communication system. When generating a pilot signal block that is shorter than the length of a data signal, a frequency for each predetermined pilot signal block is transitioned so as to guarantee frequency domain channel estimation performance. A cyclic prefix according to the length of the transitioned pilot signal is added to the pilot signal, a data signal is time division multiplexed together with the pilot signal, and a resultant signal is transmitted through an antenna. In advance to this, a position of a subcarrier for transmitting the pilot signal and the data signal is determined, a data signal is mapped on the determined subcarrier, and in this instance, diversity on the channel for a symbol is used to map the data signal on the transmission method using one of the localized FDMA (L-FDMA) channel and the distributed FDMA (D-FDMA) channel. Therefore, the frequency resolution in the frequency domain is maintained to thus provide high-quality channel estimation performance.
