1. A feedback method, applied to a data receiver, and comprising:
determining that a geographical distance between the data receiver and a data transmitter exceeds a quality of service (QOS) communication distance; and
sending out-of-range feedback information, wherein the out-of-range feedback information is configured to indicate that the geographical distance between the data receiver and the data transmitter exceeds the QoS communication distance;
wherein sending the out-of-range feedback information comprises at least one of:
sending the out-of-range feedback information based on a physical layer sequence;
sending the out-of-range feedback information based on a bit value of a modulation symbol; or
sending the out-of-range feedback information by a time-frequency resource for implicitly indicating the out-of-range feedback information.
