Abstract
The embodiment of the present application discloses a communication method and a communication device, which are used for establishing two same-frequency and same-coverage cells in a same frequency band, and arranging time-frequency resources used by the two cells respectively by time division or frequency division to avoid same-frequency interference, so that the two cells are backup for each other, and when an abnormality occurs in one of the two cells, the other cell can still provide services for a terminal device. Since the two cells share the frequency band, spectrum resources can be saved, and consumption of time-frequency resources is reduced. In addition, wireless resource utilization can be improved while reliability gain of a double-network system level backup is obtained.
