Abstract
One embodiment of the present invention provides a method for transmitting, by a receiving terminal, a feedback signal to a transmitting terminal in a wireless communication system, the method comprising the steps of: receiving, by the receiving terminal, a reference signal from the transmitting terminal; and transmitting, by the receiving terminal, the feedback signal for the reference signal to the transmitting terminal, wherein the feedback signal is transmitted on the basis of compensation for a phase change that occurs when the reference signal is received.
Claims14
A method of transmitting a feedback signal to a transmitting user equipment (UE) by a receiving UE in a wireless communication system, the method comprising:
- receiving information related to time-frequency resources for a reference signal;
- receiving, by the receiving UE from the transmitting UE, the reference signal through the time-frequency resources,
- wherein the reference signal is generated based on pseudo random sequence;
- and
- transmitting, by the receiving UE, the feedback signal for the reference signal to the transmitting UE,
- wherein the feedback signal is transmitted based on a phase rotation based on a time difference between a first fast Fourier transform (FFT) window for reference signal transmission at the transmitting UE and a second FFT window for reference signal reception at the receiving UE.
A receiving user equipment (UE) for transmitting a feedback signal in a wireless communication system, the receiving UE comprising:
- a transceiver;
- and
- a processor configured to:
- receive information related to time-frequency resources for a reference signal;
- receive, from a transmitting UE, the reference signal through the time-frequency resources,
- wherein the reference signal is generated based on pseudo random sequence;
- and
- transmit the feedback signal for the reference signal to the transmitting UE,
- wherein the feedback signal is transmitted based on a phase rotation based on a time difference between a first fast Fourier transform (FFT) window for reference signal transmission at the transmitting UE and a second FFT window for reference signal reception at the receiving UE.
