Methods and apparatuses for slow-fading precoding for multi-cell wireless systems are provided. At a base station of a cellular network in which a plurality of terminals are served, the base station serving pluralities of same-cell terminals and neighboring-cell terminals, and the cellular network including neighboring-cell base stations that serve respective pluralities of same-cell terminals and neighboring-cell terminals, a same-cell and one or more neighboring cells within the cellular network are selected, the same-cell and one or more neighboring cells comprising a truncated network. A plurality of slow-fading coefficients is obtained, each of the plurality of slow-fading coefficients being associated with channel state information for communication within the truncated network between a neighboring-cell base station and one of the respective same-cell terminals or neighboring-cell terminals, and a set of slow-fading precoding coefficients is generated for transmitting signals within the truncated network to same-cell terminals and neighboring-cell terminals based on the plurality of slow-fading coefficients.
