Method and apparatus for channel-related information feedback in a beamforming system
First Claim
1. A method for receiving feedback information by a transmitter in a beam forming system, the method comprising:
- determining whether a receiver is to feed back gain information about an effective channel established with the receiver using feedback mode related information between the transmitter and the receiver;
notifying the receiver of a feedback mode comprising an indicator indicating whether the gain information is to be fed back;
if the indicator is determined as a value indicating that the gain information is to be fed back, receiving the feedback information comprising the gain information; and
reconfiguring the effective channel based on the gain information, and transmitting a signal on the reconfigured effective channel.

Abstract
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for channel-related information feedback in a beamforming system, performed by a transmitter is provided. The method includes determining whether a receiver is to feed back gain information about an effective channel established between the transmitter and the receiver using channel-related information between the transmitter and the receiver, notifying the receiver of a feedback mode indicating whether the gain information is to be fed back, upon receipt of feedback information configured based on the feedback mode from the receiver, reconfiguring the effective channel based on the feedback information, and transmitting a signal on the reconfigured effective channel.

11. A transmitter for receiving feedback information in a beamforming system, the transmitter comprising:
-
a controller configured to determine whether a receiver is to feed back gain information about an effective channel established between the transmitter and the receiver using feedback mode related information between the transmitter and the receiver, and to notify the receiver of a feedback mode comprising an indicator indicating whether the gain information is to be fed back through a transceiver; if the indicator is determined as a value indicating that the gain information is to be fed back, a receiver is configured to receive the feedback information comprising the gain information; an effective channel configurer configured to reconfigure the effective channel based on the gain information; and a transmitter configured to transmit a signal on the reconfigured effective channel. - View Dependent Claims (12, 13, 14, 15)
