Abstract
Disclosed in the present application are a random access response (RAR) transmission method and device for ensuring independent transmission of RARs having different coverage enhancement levels, reducing a blind test of a physical downlink control channel performed by a terminal, and saving power consumption of the terminal. The present application provides an RAR transmission method, comprising: determining, by a network side and at least according to coverage enhancement levels corresponding to physical downlink control channels, frequency domain resources of the physical downlink control channels, wherein the frequency domain resources of the physical downlink control channels having different coverage enhancement levels are independently configured; and transmitting, by the network side, the physical downlink control channels on the frequency domain resources of the physical downlink control channels.
