VIRTUAL ANTENNA MAPPING METHOD AND VIRTUAL ANTENNA MAPPING APPARATUS FOR FEEDBACK OF VIRTUAL ANTENNA MAPPING PATTERN IN MIMO SYSTEM |
摘要 |
<p>The present invention relates to a virtual antenna mapping method for providing feedback of virtual antenna mapping information in a multi-input multi-output (MIMO) system, and an apparatus thereof. According to the present invention, the virtual antenna mapping (VAM) method of a base station having an M number of physical antennas comprises the following steps: transmitting a reference signal (RS) to a terminal in a transmission mode which supports an N number of logical antennas; receiving, from the terminal, a feed-back including information on a VAM pattern selected depending on a result of channel measurement using the reference signal; and transmitting a signal to the terminal through the M number of physical antennas by applying the VAM pattern. The VAM pattern is for mapping the N number of data streams corresponding to the N number of logical antennas, respectively, with the M number of physical antennas.</p> |
