Abstract
A method and apparatus for transmitting data performed by at least one base station (BS) in a wireless communication system is provided. First signals are repsectively mapped to a first Orthgonal Frequency Division Multiplexing (OFDM) symbol of a first BS and a second BS, and are transmitted. A second signal, having a θ shifted phase of the first signal, is mappped to a second OFDM symbol, and is transmitted by the first BS. The repective first signals and the second signal are transmitted in a same subcarrier in a frequency domain.
Claims14
A method for transmitting data performed by at least one base station (BS) in a wireless communication system, the method comprising:
- transmitting respective first signals of a first BS and a second BS, the respective first signals being mapped to a first Orthgonal Frequency Division Multiplexing (OFDM) symbol, and
- transmitting a second signal having a θ shifted phase of the first signal, by the first BS, the second signal being mapped to a second OFDM symbol,
- wherein the repective first signals and the second signal are transmitted in a same subcarrier in a frequency domain.
A method of processing data performed by a user equipment in a wireless communication system, the method comprising:
- receiving a first signal from a base station (BS) through a first Orthogonal Frequency Division Mutiplexing (OFDM) symbol;
- receiving a second signal, having a θ shifted phase of the first signal, from the BS through a second OFDM symbol contiguous to the first OFDM symbol, and
- decoding the first signal and the second signal.
A transmitter in a wireless communication system, the transmitter comprising:
- a Radio Frequency (RF) unit configured to transmit and receive signals, and
- a processor coupled to the RF unit and configured to:
- map a first signal to a first Orthogonal Frequency Division Multiplexing (OFDM) symbol and transmit the first signal mapped to the first OFDM symbol;
- map a second signal, having a phase θ shifted phase of the first signal, to a second OFDM symbol contiguous to the first OFDM symbol and transmit the second signal mapped to the second OFDM symbol;
- wherein the first signal and the second signal are transmitted in a same subcarrier in a frequency domain.
