Patent ID: 8472464

Claim:
A method for information transmission performed by a transmitter in a wireless communication system, the method comprising: generating a first information sequence based on a first transmission symbol and a first resource index; generating a second information sequence based on a second transmission symbol and a second resource index; generating a third information sequence based on a third transmission symbol and a third resource index; generating a fourth information sequence based on a fourth transmission symbol and a fourth resource index; generating a fifth information sequence based on a fifth transmission symbol and a fifth resource index; generating a sixth information sequence based on a sixth transmission symbol and a sixth resource index; and transmitting the first information sequence, the second information sequence, and the third information sequence through a first antenna, and transmitting the fourth information sequence, the fifth information sequence, and the sixth information sequence through a second antenna, wherein the fifth transmission symbol is a complex conjugate of the first transmission symbol, and the fourth transmission symbol is obtained by appending a minus sign to a complex conjugate of the second transmission symbol.
