Slow-Fading Precoding for Multi-Cell Wireless Systems

Abstract

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