Abstract
A data sending method and apparatus, a storage medium, and a sending end. The method includes: determining an activation instruction, the activation instruction using multiple bits to indicate sending end logical channels to be used of each RB; and for each RB, a sending end PDCP entity duplicates a PDCP data packet according to the number n of the sending end logical channels to be used of the RB, and sends the duplicated PDCP data packets to a receiving end by means of the sending end logical channels to be used, the maximum value of the number n of the sending end logical channels of each RB being greater than 2. The solution of the present invention can improve the accuracy of an instruction, thereby facilitating improving transmission resource utilization efficiency.
