Abstract

This application relates to a communication method and a communications device. The communication method includes: determining, a first signal to be sent on a first uplink carrier; determining a second signal to be sent on a second uplink carrier, where the first uplink carrier corresponds to a first radio access technology, and the second uplink carrier corresponds to a second radio access technology; and when a first transmission timing corresponding to the first signal is different from a second transmission timing corresponding to the second signal, and if the first signal and the second signal overlap in time domain, sending, a third signal, where the third signal is the second signal, or is the second signal or a part of the first signal, where the part of the first signal is carried on a symbol that does not overlap with a symbol corresponding the second signal.
