Abstract

Disclosed are a data receiving device and method for generating and transmitting feedback information in a multi-antenna system using group antennas, and a data transmitting device and method for transmitting a user's data stream according to a transmission mode selected according to the feedback information. The receiving device generates feedback information based on the maximum channel quality information, the antenna group label associated with the maximum channel quality information, the level information, and the remaining channel quality information associated with the level information, and sends the feedback information to the sending device. The sending device selects one of the multi-user mode and the single-user mode as the transmission mode according to the feedback information, and sends the user's data stream via multiple antenna groups or one antenna group according to the selected transmission mode.

Description

Technical field [0001] The present invention generally relates to an apparatus and method for data transmission / reception in a multi-antenna system and a system using the apparatus and method, and, more specifically, the present invention relates to an apparatus and method for transmitting / receiving data through antenna grouping and using the same. System of devices and methods. Background technique [0002] Generally, unlike the wired channel environment, the wireless channel environment exhibits lower reliability due to multipath interference, blind zone, propagation loss, time-varying noise, interference, etc. In a mobile communication system, this is a typical reason that hinders the increase in data transmission rate or data rate. Therefore, in order to realize a high-speed wireless environment for providing high-speed services, there is an urgent need to solve the aforementioned problems. [0003] Multiple-input multiple-output (MIMO) systems are traditional technologies th...
