1. A communication method, comprising:
receiving first signaling, wherein the first signaling indicates to deactivate packet data convergence protocol (PDCP) duplication transmission of a first logical channel;
determining, depending on whether a third logical channel in an activated state and the first logical channel belong to a same media access control (MAC) entity, whether an association relationship between a carrier and the third logical channel in the activated state applies, wherein the first logical channel and the third logical channel in the activated state belong to a same radio bearer, and the radio bearer is configured for PDCP duplication transmission; and
transmitting data of the third logical channel.
