The present application discloses a communication method and device. The method includes: when an instruction to activate a secondary carrier is received, activate the secondary carrier; perform one or more serving cell searches; acquire timing information of the serving cell, and synchronize with the serving cell. Corresponding devices are also disclosed. With the solution of the present application, it is not necessary to wait for the network side to configure the DMTC period, but to obtain the timing of the secondary carrier service area by performing continuous cell search, which can speed up the activation of the secondary carrier.
