The present disclosure relates to communication methods and apparatus. In one example method, a terminal device receives first indication information, where the first indication information is used to indicate grouping information of N control resource sets in M control resource sets, N is less than M, and N and M are positive integers greater than or equal to 1. The terminal device determines grouping information of K control resource sets other than the N control resource sets in the M control resource sets based on the first indication information.
