We consider a multiuser downlink transmission from a base station with multiple antennas (MIMO) to mobile terminals (users) with a single antenna. using orthogonal frequency division multiplexing (OFDM). Channel conditions are reported by a feedback from users with limited rate. and the base station schedules transmissions and beamforms signals to users. https://www.markymarkscott.com/product-category/gold-snail-emulsion/
