  • Patent number: 10926887
    Abstract: The present disclosure provides a computer implemented method of providing an indicator useful for piloting an aircraft. The aircraft comprises an antenna configured to communicate with a transceiver. The method comprises: obtaining an antenna envelope characterizing directions relative to the aircraft for which a directive gain of the antenna exceeds a predetermined threshold; determining a direction of the transceiver relative to the aircraft; calculating a maneuvering range of the aircraft by comparing the antenna envelope and the transceiver direction, wherein the maneuvering range is indicative of eligible orientations of the aircraft for maintaining the transceiver within the antenna envelope; and outputting data indicative of the maneuvering range.

  • Patent number: 10862574
    Abstract: A method for repetition of uplink transmissions comprises: a repeater apparatus, aka uplink repeater, has a controller, a downlink receiver and an uplink transmitter and receiver. Use the downlink receiver to receive a downlink signal from a base station whose cell the uplink repeater is serving. For downlink frame(s) thus received: the controller demodulates at least a portion of the downlink frame and extracts MAP_D data describing allocation of an uplink transmission in upcoming uplink frame(s) to be transmitted after the downlink frame; controller determines a subset of UL transmission allocations to be repeated, to define a subset of mobile stations in the cell, whose uplink transmissions are to be repeated; the uplink receiver receives the UL transmissions to be repeated from each mobile station, and repeats the UL transmissions to be repeated by commanding the UL transmitter to send the content.
