摘要： Disclosed is a transmitting/receiving method in a multi-user multiple-input multiple-output (MU-MIMO) channel. The transmitting method includes: performing QR decomposition on a Hermitian transpose matrix of a channel matrix to obtain a first matrix and a second matrix as a triangular matrix; obtaining a preprocessing matrix by using the first matrix; and forming an effective channel based on the preprocessing matrix by a block triangulation technique.

摘要： Provided are a method and an apparatus for detecting the locations of terminals in a multi-node system. A plurality of nodes transmit location reference signals which are distinguished by node, and a terminal performs feedback of channel information on each node using the location reference signals. Various signaling for detecting the locations of the terminals may be performed for each node, that is, for each point, rather than cell-based signaling.
