Claim 10:
11. A reference signal configuration method, comprising:
determining, by a second communication node, a resource used by a reference signal via signaling transmitted by a first communication node; or
predefining, by a second communication node and a first communication node, a resource used by the second communication node for transmitting a reference signal; and wherein
the signaling comprises information about multi-level bandwidth structure, where the information about the multi-level bandwidth structure comprises at least one of: a number M of levels, a number of bandwidths at an (n+1)-th level included in one bandwidth at an n-th level, selection information of multi-level bandwidth structures, a bandwidth length of a minimum bandwidth, a bandwidth length corresponding to one bandwidth at a j-th level, a total number of bandwidths at an m-th level, or a number of multi-level bandwidth structures, where n belongs to {0, 1, . . . , M−2}, m belongs to {1, 2, . . . , M−1}, j belongs to {0, 1, . . . , M−1}, and M is a natural number and is the number of levels of the multi-level bandwidth structure; and
a transmission bandwidth of the reference signal is a bandwidth included in the multi-level bandwidth structure, one bandwidth at the n-th level of the multi-level bandwidth structure comprises one or more bandwidths at the (n+1)-th level, and the selection information of multi-level bandwidth structures indicates that one or more multi-level bandwidth structures are selected from a plurality of predetermined multi-level bandwidth structures.
