1. A communication method, comprising:
determining N configuration parameter sets for a terminal device, wherein each of the N configuration parameter sets comprises a parameter for detecting a candidate downlink control channel, and N is an integer greater than or equal to 2;
sending information about the N configuration parameter sets to the terminal device, wherein each of the N configuration parameter sets comprises a parameter of a time domain resource set of the candidate downlink control channel, and wherein a candidate downlink control channel resource corresponding to an ith configuration parameter set in the N configuration parameter sets is a subset of the candidate downlink control channel resource corresponding to an (i−1)th configuration parameter set comprises at least one of the following:
each of the N configuration parameter sets comprises a candidate downlink control channel detection period, the candidate downlink control channel detection period comprised in the ith configuration parameter set is greater than the candidate downlink control channel detection period comprised in the (i−1)th configuration parameter set, and the candidate downlink control channel detection period comprised in the ith configuration parameter set is an integer multiple of the candidate downlink control channel detection period comprised in the (i−1)th configuration parameter set;
each of the N configuration parameter sets comprises a control resource set parameter, and a control resource set of the candidate downlink control channel corresponding to the ith configuration parameter set is a subset of the control resource set of the candidate downlink control channel corresponding to the (i−1)th configuration parameter set;
each of the N configuration parameter sets comprises a bandwidth part, and a search space of the candidate downlink control channel corresponding to the bandwidth part corresponding to the ith configuration parameter set is a subset of the search space of the candidate downlink control channel corresponding to the bandwidth part corresponding to the (i−1)th configuration parameter set; or
each of the N configuration parameter sets comprises the bandwidth part, and the control resource set of the candidate downlink control channel corresponding to the bandwidth part corresponding to the ith configuration parameter set is a subset of the control resource set of the candidate downlink control channel corresponding to the bandwidth part corresponding to the (i−1)th configuration parameter set; and
sending second downlink control information to a terminal device group, wherein the second downlink control information comprises at least one piece of indication information, and each of the at least one piece of indication information is used to indicate a configuration parameter set in the N configuration parameter sets for one or more terminal devices in the terminal device group.
