1. A reference signal management method, comprising:
receiving, by a terminal device, first information sent by a network device, wherein the first information is used to indicate a plurality of first reference signal groups on a first carrier, a correspondence between the plurality of first reference signal groups and a plurality of first reference signals on a second carrier, and the plurality of first reference signal groups comprise at least two reference signals;
receiving, by the terminal device, the plurality of first reference signal groups sent by the network device;
measuring, by the terminal device, signal quality of the plurality of first reference signal groups; and
determining, by the terminal device, N first reference signal groups with optimal signal quality in the plurality of first reference signal groups.
