Abstract
A ground station communicates with a satellite having a field of view (FOV), the satellite directly communicating with user equipment (UE) over uplink signals and downlink signals. The ground station has a Dynamic Time Division Duplex (DTDD) controller configured to establish UE uplink time slots during which the UE sends UE uplink signals, the UE uplink time slots based on a unique delay for the UE, whereby UE uplink signals are received at the satellite during a same satellite uplink time slot. The controller avoids overlapping uplink and downlink signals being received at the satellite, as well as at the UE.
