A communication method and an apparatus are disclosed. The method includes: A first communications device receives first DCI from a network device in a first discontinuous reception active time, where the first DCI is used to indicate new uplink or downlink data transmission; the first communications device does not expect to receive a PDCCH from the network device in a first time period after the first discontinuous reception active time, where a start moment of the first time period is an end moment of the first discontinuous reception active time, and an end moment of the first time period is in a second discontinuous reception active time; and the first communications device monitors the PDCCH after the first time period.
