Apparatus and method for transmitting/receiving data in communication system

摘要

Disclosed is an apparatus for transmitting data in a communication system, including: a receiving unit configured to receive signals from multi-users by a multi-user-multi input multi output (MIMO) scheme and acquire channel information from the users; a calculation unit configured to calculate precoding vectors for the users using the channel information; a precoding unit configured to precode data of the users using the precoding vectors; and a transmitting unit configured to transmit the precoded data to users by the multi user-MIMO scheme.

1. An apparatus for transmitting data in a communication system, the apparatus comprising:
a receiving unit configured to receive signals from multiple users by a multi-user-multi input multi output (MIMO) scheme and acquire channel information from the users; a calculation unit configured to calculate, using a processor, precoding vectors for the users using the channel information; a precoding unit configured to precode, using a processor, the data using the precoding vectors for the users; and a transmitting unit configured to transmit the precoded data to the users by the multi user-MIMO scheme, wherein the calculation unit sequentially calculates precoding vectors for users sequentially selected from the users, and uses precoding vectors for previously selected users among the users to select a next user and to calculate a precoding vector for the next user.
