Patent ID: 8761090

Claim:
A method for uplink transmission in a multi-antenna system, the method comprising: generating a plurality of first uplink transmission symbols and a plurality of second uplink transmission symbols by performing discrete Fourier transform (DFT) spreading on a plurality of modulation symbols generated by modulating encoded bits; transmitting the plurality of first uplink transmission symbols on a physical uplink shared channel (PUSCH) through a plurality of antennas by using a first spatial process performed on the plurality of first uplink transmission symbols in odd-numbered orthogonal frequency division multiplexing (OFDM) data symbols; and transmitting the plurality of second uplink transmission symbols on a physical uplink shared channel (PUSCH) through the plurality of antennas by using a second spatial process performed on the plurality of uplink second transmission symbols in even-numbered OFDM data symbols, wherein at least one row or at least one column of a first spatial processing matrix used in the first spatial process is switched to configure a second spatial processing matrix used in the second spatial process, and wherein the first spatial processing matrix is different from the second spatial processing matrix.
