摘要: A radio communication system is provided. An uplink transmission method of a user equipment in a radio communication system includes performing Fourier transform on one or more data sequences to generate one or more first frequency-domain sequences, applying precoding for multi-antenna transmission to the one or more first frequency-domain sequences to generate one or more second frequency-domain sequences; performing inverse Fourier transform on the one or more second frequency-domain sequences to generate one or more transmission symbols, and transmitting the one or more transmission symbols via multiple antennas.
