Claim 6:
7. The method of claim 1, wherein
the signaling comprises the information about the multi-level bandwidth structure, wherein 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 belongs to a bandwidth included in one 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.
