Abstract

Systems, methods, and non-transitory media are provided for synchronization of multi-user uplink transmissions. An example method can include receiving, by a user terminal, a downlink radio frame transmitted by a satellite; determining, by the user terminal, a downlink propagation delay associated with the downlink radio frame and an uplink propagation delay associated with an uplink radio frame from the user terminal to the satellite; based on the downlink propagation delay and the uplink propagation delay, determining, by the user terminal, an uplink transmission delay indicating an amount of time to delay a transmission of the uplink radio frame to the satellite so the uplink radio frame is received at the satellite at a same target time as one or more additional uplink radio frames from one or more additional user terminals; and transmitting, by the user terminal, the uplink radio frame at a time corresponding to the uplink transmission delay.
