The invention relates to the technical field of
Internet of Things communication, and discloses a high-efficiency feedback confirmation method suitable for LoRa transmission, and the method comprises the following steps: S1, a step of data packet transmitting, namely a step of enabling a transmitting end to transmit a data packet; S2, a receiving step, namely a step that, after receiving one data packet, a receiving end does not need to immediately feed back ACK but waits for the indication of the transmitting end; and S3, a step of feedback transmission, namely a step that the transmitting end comprehensively considers local cache data and
business data characteristics to determine whether to continue to send data, if a plurality of data packets need to be transmitted, the transmission is continued, and if ACK feedback needs to be received, the receiving end is indicated to send feedback in the following data packets, and a receiving window is opened at the same time. When a plurality of data packets are transmitted, the transmitting end does not need to frequently switch the receiving and transmitting mode, and only needs to switch the receiving and transmitting mode once, so that the
switching time and the
software control complexity are greatly reduced, the transmission of the plurality of data packets can be completed by only needing one BlckACK frame, and the empty interface time is saved.
