Method for grouping transmission antennas in mobile communication system including multiple transmission/reception antennas

摘要

Disclosed is a method for configuring transmission antenna groups in a mobile communication system with multiple transmission antennas and multiple reception antennas. The method includes the steps of: receiving a first matrix having a size of 'N_txN_t', which corresponds to N_t number of transmission antennas, fedback from the mobile terminal, generating combinations of sub-matrixes of the first matrix corresponding to N_r number of reception antennas, and calculating sums of maximum eigenvalues; determining combinations of the sub-matrixes having a maximum value from among the calculated sums of eigenvalues to be transmission antenna groups for the N_t number of transmission antennas; and transmitting different relevant symbols from each other through the transmission antenna groups.
