Data retransmission method, electronic equipment and computer readable storage medium

The invention discloses a data retransmission method, electronic equipment and a computer readable storage medium, and belongs to the field of communication. According to the invention, a message data set of a current transmission period is sent to a receiving end, and the message data set comprises a plurality of data sub-blocks; detecting whether indication information fed back by the receiving end is received within a preset duration, the indication information indicating the serial number ID corresponding to the data sub-block which fails to be verified by the receiving end; and after it is determined that the indication information is received within the preset duration, extracting the data sub-block associated with the serial number ID in the indication information from the retransmission cache region as to-be-retransmitted data, and sending the to-be-retransmitted data to a receiving end. According to the invention, on the basis of ensuring correct data transmission as much as possible, the bandwidth r
