Abstract

See full text

There is provided a method and apparatus in which a user equipment demodulates a downlink signal in a wireless communication system. The user equipment receives a first orthogonal frequency division multiplexing (OFDM) signal from a first node serving the mobile station, receives a second OFDM signal from a second node different from the first node, and demodulates the first OFDM signal and the second OFDM signal in a fast Fourier transform (FFT) section. The first OFDM signal and the second OFDM signal are either normal mode signals each having a first cyclic prefix (CP) or cooperative mode signals each having a second CP, and the second CP has a longer length than the first CP.
