摘要

Here, the authors propose a beamforming (BF) scheme for the downlink transmission of a hybrid satellite-terrestrial network. The authors first formulate a constrained optimisation problem to maximise the minimal quality-of-service of the terrestrial users subject to the interference constraint of the satellite user and the transmit power budget of the base station (BS). Then, by using the uplink-d...
