Device methods and for its reporting channel state information for the 3-dimensional beam forming in a wireless communication system

摘要

An object of the present invention is to provide an apparatus of the method and for the reporting channel state information for the 3-dimensional beam forming in a wireless communication system. According to an example of The present invention, a method of a terminal in a wireless communication system transmits channel state information (CSI) receives a reference signal from a base station supporting a 2-dimensional antenna array step When, it is possible to have the steps of: determining a CSI using a reference signal, and transmitting the determined CSI to the base station. CSI includes a channel quality indicator (CQI), CQI is code word - versus - can be determined using the layer mapping rules. The code word for the first dimension - versus - layer mapping rules and the code word for the second-dimensional - versus - are different from each other and the layer mapping rules.FIELD 24
