1. A quasi co-location indication method, wherein the method comprises:
receiving quasi co-location indication information, wherein the quasi co-location indication information indicates:
M antenna port groups corresponding to a first reference signal resource, each of the M antenna port groups comprises one or more code division multiplexing (CDM) groups of the first reference signal resource, each CDM group of the CDM groups comprises a plurality of antenna ports, any two of the plurality of antenna ports that are in a same one of the M antenna port groups have a quasi-co-location relationship, and M is an integer greater than 1; and
a grouping manner of the CDM groups, wherein the grouping manner is at least one of a time domain grouping manner or a frequency domain grouping manner; and
determining, for at least one of the CDM groups, the quasi-co-location relationship of the two or more of the plurality of antenna ports of at least one of the one or more antenna port groups of the first reference signal resource based on the quasi-co-location indication information,
wherein
the quasi co-location indication information includes an identifier indicating which one of at least two quasi co-location rules is to be applied for grouping a preset quantity of antenna ports into one antenna port group,
the at least two quasi co-location rules include a corresponding rule-defined order according to which the preset quantity of antenna ports are to be arranged in the one antenna port group in response to a processing of the identifier included in the received quasi co-location information to determine which one of the at least two quasi co-location rules is to be applied, and
the corresponding rule-defined order is one of an ascending or a descending order of the antenna ports in the one antenna port group.
