Abstract
The present application discloses a method for transmitting a signal from a transmitting end to a receiving end in a wireless communication system. Specifically, the method comprises the steps of: configuring a precoder set including one or more precoders; precoding the signal by cyclically applying the one or more precoders in a specific resource unit; and transmitting the precoded signal to the receiving end, wherein at least one of the size of the precoder set and the one or more precoders is determined on the basis of the mobility of the receiving end.
Claims12
A method of transmitting a signal from a transmission end to a reception end in a wireless communication system, the method comprising:
- receiving information on at least one preferred precoder from the reception end;
- setting a reference precoder set within a predetermined beamforming angle range based on the at least one preferred precoder;
- composing a precoder set including one or more precoders from the reference precoder set based on a mobility of the reception end;
- cycling and applying the one or more precoders in specific resource units to precode the signal;
- and
- transmitting the precoded signal to the reception end,
- wherein at least one of a size of the precoder set and the one or more precoders is determined based on the mobility of the reception end.
A transmission apparatus in a wireless communication system to transmit a signal from a transmission end to a reception end, the transmission apparatus comprising:
- a radio frequency (RF) transceiver;
- and
- a processor,
- wherein the processor is configured to:
- control the RF transceiver to receive information on at least one preferred precoder from the reception end,
- set a reference precoder set within a predetermined beamforming angle range based on the at least one preferred precoder,
- compose a precoder set including one or more precoders from the reference precoder set based on a mobility of the reception end,
- cycle and apply the one or more precoders in specific resource units to precode the signal, and
- control the RF transceiver to transmit the precoded signal to the reception end,
- wherein at least one of a size of the precoder set and the one or more precoders is determined based on the mobility of the reception end.
