Patent ID: 11522642

Abstract:
Systems and methods for intelligent packet repetition in mobile satellite service links to overcome channel blockages. One example method includes transmitting and receiving packetized wireless communications between first and second communications devices via a bidirectional wireless link. The method includes receiving, by a first communications device from a second communications device, feedback information including an indication of a blockage in the communication channel, the indication including information indicating the presence and extent of the blockage, wherein the feedback does not include status indications for individual received packets. The method includes, responsive to receiving the indication of a blockage in the communication channel, determining a packet repeat value based on the feedback information, wherein the packet repeat value is greater than one. The method includes modifying a transmit signal of the bidirectional wireless link to repeat transmitted packets based on the packet repeat value and transmitting the downlink signal. The decision to turn on packet repetition, the number of repeats, may also be informed by the geographic location of the receiver.
