Title:
METHOD AND APPARATUS FOR TRANSMITTING FEEDBACK ABOUT CHANNEL HAVING SPATIAL CORRELATION
Document Type and Number:
WIPO Patent Application WO/2015/133835
Kind Code:
A1
Abstract:
A method for a data signal on channels having spatial correlations by a Base Station (BS) is provided. The method includes estimating the spatial correlations of the channels, selecting a part of the channels based on a result of the estimation and transmitting a signal for channel estimation on the selected partial channels, and receiving channel estimation information estimated based on the signal from a User Equipment (UE) and generating a data signal to be transmitted to the UE on the channels using the channel estimation information.
