Abstract: A method and apparatus of transmitting a reference signal in a wireless communication system is provided. A reference signal sequence is generated by using a pseudo-random sequence. A portion or entirety of the reference signal sequence is mapped to at least one resource block and is transmitted. The pseudo-random sequence is generated by a gold sequence generator which is initialized with initial values obtained by using cell identifier. The reference signal provides low PAPR and high cross correlation characteristic.

Abstract: In an aspect, a method for transmitting data in a wireless communication system is provided. A wireless device determines a subcarrier and a subcarrier group to which a data sequence is allocated. The wireless device modulates the data sequence by a transmit filter to generate a data stream. A waveform of the transmit filter is determined based on the subcarrier and the subcarrier group. The wireless device generates a transmission signal based on the data stream. The wireless device transmits the transmission signal through the subcarrier. The transmission signal is cyclostationary.
