Very/ High Throughput Satellites (V/HTS) systems will play an important role in integrated satellite-terrestrial networks. A key technological evolution to cope with the ever-growing demand for higher data rates in bandwidth-limited V/HTS systems is to shift their feeder links to the Q/V-band (40/50 GHz). Even though up to 5 GHz of bandwidth is available in the Q/V-band, tens of spatially separated feeder links with a full re-use of the uplink frequency resources are required to support the aggregated user link bandwidth.
