Abstract
A feedback method, including: determining that a geographical distance between a data receiver and a data transmitter exceeds a quality of service (QoS) communication distance; sending out-of-range feedback information, and 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.
Claims20
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.

A feedback method, applied to a data transmitter, and comprising:
- detecting out-of-range feedback information, wherein the out-of-range feedback information is configured to indicate that a geographical distance between a data receiver and the data transmitter exceeds a quality of service (QOS) communication distance;
- and
- determining whether to resend data according to an out-of-range feedback information detection result;
- wherein detecting the out-of-range feedback information comprises at least one of:
- detecting the out-of-range feedback information based on a physical layer sequence;
- detecting the out-of-range feedback information based on a bit value of a modulation symbol;
- or
- detecting the out-of-range feedback information by a time-frequency resource for implicitly indicating the out-of-range feedback information.
5 more elements
A data transmission system, comprising:
- a data transmitter and a data receiver, wherein:
- the data receiver is configured to determine that a geographical distance between the data receiver and a data transmitter exceeds a quality of service (QOS) communication distance, and send 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;
- and
- the data transmitter is configured to determine to stop resending the data when receiving the out-of-range feedback information;
- 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.
