Abstract

The invention discloses a data sending method in an industrial internet of things, which comprises the following steps that: a second communication node feeds back first channel state information to a first communication node, the first communication node sends uplink detection reference signal configuration information, and the second communication node sends an uplink detection reference signal, the first communication node determines second channel state information according to the receiving quality of the uplink sounding reference signal, modulates the N data bits, sends a plurality of modulation symbols obtained after modulation to the second communication node, receives the plurality of modulation symbols, verifies the N data bits obtained after processing, and generating feedback information containing the receiving success or failure information to the first communication node, receiving the feedback information by the first communication node, and if the feedback information contains the receiving failure information, modulating the N data bits and resending the modulated N data bits to the second communication node. According to the invention, the reliability and efficiency of data channel transmission can be improved.
