1. A communication method, comprising:
receiving, by a first communications device, first downlink control information (DCI) from a network device in a first discontinuous reception active time, wherein the first DCI indicates new uplink or downlink data transmission;
skipping listening on, by the first communications device, a physical downlink control channel (PDCCH) from the network device in a first time period after the first discontinuous reception active time, wherein 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
listening on, by the first communications device, the PDCCH after the first time period,
wherein the receiving of the first DCI from the network device in the first discontinuous reception active time comprises:
receiving, by the first communications device, at least one piece of the first DCI from the network device in a second time period in the first discontinuous reception active time, and failing to receive, by the first communications device, the first DCI from the network device in a last but X−1 slot of the first discontinuous reception active time, wherein
X is an integer, X=minimum KO, or X=Z, or X=max(minimum KO, Z), minimum KO represents a minimum value of a slot interval between the PDCCH and a physical downlink shared channel (PDSCH), Z represents a first constant value, Z is a positive integer, a start moment of the second time period is a start moment of a last but X−2 slot of the first discontinuous reception active time, and an end moment of the second time period is the end moment of the first discontinuous reception active time.
