1. A communication method, comprising:
receiving first configuration information, wherein the first configuration information comprises first indication information and second indication information, the first indication information indicates a search space configuration of a scheduling cell, and the second indication information indicates a search space configuration of at least one scheduled cell corresponding to the scheduling cell;
determining a first monitoring span pattern based on the search space configuration of the scheduling cell and the search space configuration of the at least one scheduled cell, wherein the first monitoring span pattern comprises N monitoring spans in a first time unit, and N is a positive integer; and
monitoring a first downlink control channel based on the first monitoring span pattern, wherein the first downlink control channel carries downlink control information of the scheduling cell or downlink control information of the at least one scheduled cell, wherein monitoring the first downlink control channel based on the first monitoring span pattern comprises:
determining a first monitoring capability based on the search space configuration of the scheduling cell, the search space configuration of the at least one scheduled cell, and information about a capability supported by a terminal device, or based on information about a capability supported by a terminal device, wherein the first monitoring capability comprises a monitoring capability of monitoring a downlink control channel by the terminal device in each of the N monitoring spans; and
monitoring the first downlink control channel based on the first monitoring capability;
wherein the first monitoring capability is max{C(i)}, and C(i) is a monitoring capability in an ith monitoring span in the N monitoring spans; and
C(i)=r1*C1+M(i)*r2*C1, wherein
C1 is a monitoring capability of monitoring a downlink control channel of one cell by the terminal device in each of the N monitoring spans, M(i) is a number of scheduled cells that are configured in the ith monitoring span and that correspond to the scheduling cell, r1 and r2 are real numbers less than or equal to 1 and greater than 0, and i is a positive integer less than or equal to N.
