BASE STATION AND CONTROL METHOD THEREOF

摘要

Disclosed in the present invention are a base station device and a control method of the base station device. The base station device achieves an effect of reducing overhead caused by feedback information based on a code book received from a terminal, and an effect of improving multiuser-multiple input and multiple output (MU-MIMO) performance by increasing accuracy of the feedback information in an environment of receiving and transmitting a signal by an MU-MIMO method.
