Method and apparatus for signal transmission in wireless communication system
First Claim
1. A transmitter comprising:
- an information processor configured to generatea first information sequence, for a first antenna, based on a first transmission symbol and a first resource index, anda second information sequence, for a second antenna, based on a second transmission symbol and a second resource index different from the first resource index,wherein the first resource index indicates a first resource block and the second resource index indicates a second resource block, which is different from the first resource block;
a reference signal generator operatively coupled to the information processor and configured to generatea first reference signal sequence, for the first antenna, based on the first resource index, anda second reference signal sequence, for the second antenna, based on the second resource index; and
the first antenna and the second antenna which are respectively configured to simultaneously transmit a first signal generated based on the first information sequence and the first reference signal sequence, and a second signal based on the second information sequence, and the second reference signal sequence.

Abstract
Provided are a method and an apparatus for signal transmission in a wireless communication system. The apparatus comprises: an information processor for generating a first information sequence based on a first transmission symbol and a first resource index, and a second information sequence based on a second transmission symbol and a second resource index; a reference signal generator for generating a different reference signal depending upon whether a first resource block indicated by the first resource index and a second resource block indicated by the second resource index are the same; and an antenna for transmitting a signal generated based on the first information sequence, the second information sequence, and the reference signal sequence.

8. A method for signal transmission performed by a transmitter in a wireless communication system, the method comprising:
-
generating a first information sequence, for a first antenna of the transmitter, based on a first transmission symbol and a first resource index, and generating a second information sequence, for a second antenna of the transmitter, based on a second transmission symbol and a second resource index different from the first resource index, wherein the first resource index indicates a first resource block and the second resource index indicates a second resource block, which is different from the first resource block; generating a first reference signal sequence, for the first antenna, based on the first resource index and a second reference signal sequence, for the second antenna, based on the second resource index; and simultaneously transmitting a first signal, generated based on the first information sequence and the first reference signal sequence, through the first antenna, and a second signal, generated based on the second information sequence and the second reference signal sequence, through the second antenna.
