Zusammenfassung:The invention belongs to the technical field of mobile communication, and particularly relates to a data sending method based on packet data convergence protocol replication, which comprises the following steps that: a terminal sends a sounding reference signal to a network end; a network terminal measures the sent sounding reference signal and executes a PD decision; the network terminal executesa PD replication function according to the PD decision and determines a command in PDC MAC CE; the network end sends a command in the PDC MAC CE to the terminal; the terminal executes a PD function or stops the PD function according to the received command in the PDC MAC CE; the network terminal and the terminal send PD copy data to each other. According to the method, under the condition that the complexity of a wireless access network is not increased, the reliability of 1-10 and the time delay requirement of 1 millisecond are met at the same time, meanwhile, the PD function is applied to the switching proces
