Techniques for determining interference-suppressing downlink transmission parameters in a wireless network using coordinated multi-point (CoMP) transmission are disclosed. In each of several iterations of an exemplary method, a tentative user-specific antenna beam-forming vector for the antennas of the first cell is formed for each of several first mobile stations served by the cell and for each of several second mobiles in neighboring cells, based on a most recent tentative virtual allocation of uplink transmitter power to each of the mobile stations and virtual uplink signal-to-noise-plus-interference ratios for the mobile stations that account for inter-cell interference. Further, a current tentative allocation of downlink transmitter power to each of the first mobile stations is determined for each iteration, based on the tentative user-specific antenna beam-forming vectors for the first cell, a pre-determined transmitter power constraint for the first cell, and target signal-to-noise-plus-interference ratios for the first mobile stations.
