Abstract :
A technique is developed, by which a massive antenna array simultaneously can: (i) coherently beamform to a set of terminals, for which estimated channel state information is available; and (ii) broadcast public information to another set of terminals, for which no channel state information is available. The broadcast information does not interfere with the beamforming as it is placed in nullspace of the channel matrix collectively seen by the terminals targeted by the beamforming.
