This disclosure relates to a communication method and a device. When a terminal device determines not to monitor DCP on a first DCP monitoring occasion, the terminal device wakes up on a first group of carriers within first DRX on duration associated with the first DCP monitoring occasion, and wakes up or sleeps on a second group of carriers within second DRX on duration associated with the first DCP monitoring occasion. The first group of carriers includes one or more carriers configured for the terminal device, a first DRX configuration is applied to the first group of carriers, the first DRX on duration corresponds to the first DRX configuration, the second group of carriers includes one or more carriers configured for the terminal device, a second DRX configuration is applied to the second group of carriers, and the second DRX on duration corresponds to the second DRX configuration.

The application discloses example methods and apparatuses. One example method includes receiving, by a terminal, a power saving signal sent by a network device, wherein the power saving signal is used to indicate statuses of the terminal on N frequency resource units, and N is an integer greater than 1.

By applying the technical solutions, the statuses of the terminal on the plurality of frequency resource units are indicated by using one power saving signal, without the need to correspondingly indicate the statuses of the terminal on the plurality of frequency resource units by using a plurality of power saving signals. This can reduce signaling overheads.
