Method and apparatus for performing fractional beamforming by large-scale MIMO in a wireless communication system

摘要

A method for performing fractional beamforming using a massive antenna array at a Base Station (BS) in a wireless communication system is disclosed. The method includes dividing the massive antenna array by rows or by columns into partitions, receiving feedback information about the partitions from a User Equipment (UE), determining sub-precoders for the partitions based on the feedback information, and transmitting a signal to the UE by performing beamforming using the sub-precoders and a linking precoder that links the partitions to each other.

1. A method for performing fractional beamforming using a massive antenna array at a Base Station (BS) in a wireless communication system, the method comprising:
dividing the massive antenna array by rows or by columns into partitions; receiving feedback information about the partitions from a User Equipment (UE); determining a sub-precoder for the partitions based on the feedback information; and transmitting a signal to the UE by performing beamforming using the sub-precoder and a linking precoder that links the partitions to each other, wherein each of the partitions includes the same number of antenna ports and a gap between the antenna ports is equal to or smaller than a predetermined value.
