  • Apparatus and method for feeding back channel information in wireless communication system
    Patent number: 10075220
    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). The present disclosure relates to channel information feedback in a wireless communication system, and an operation method of a receiving node includes: determining compressed channel information based on an eigenvalue decomposition of a covariance matrix regarding a channel, and transmitting, to a transmitting node, a direction index and a magnitude index representing the compressed channel information. Herein, a dimension of the compressed channel information is lower than a dimension of channel information associated with the transmitting node. Also, the disclosure includes other embodiments, different from the above described embodiment.
