Abstract
Methods for suppressing inter-cell interference during data transmission using a preceding matrix are provided. Inter-cell interference is suppressed by precoding data (or information) signals for transmission from base station to mobile or vice versa. Methods according to example embodiments also increase intra-cell data transmission rates. The precoding matrix is generated based on estimated channel coefficients for propagation channels between a base station and mobiles inside and outside the base station's coverage area.
