Claim 0:
1. A reference signal configuration method, comprising:
indicating, by a first communication node via signaling, a resource used by a second communication node for transmitting a reference signal; or
predefining, by a first communication node and a second communication node, a resource used by the second communication node for transmitting a reference signal;
wherein one or more resources constitute a resource group, wherein transmission bandwidth sets of the reference signal corresponding to different resource groups are different, or transmission bandwidth sets of the reference signal corresponding to different resources are different; and
wherein
information about a multi-level bandwidth structure of the reference signal is associated with an uplink transmission bandwidth corresponding to the second communication node,
wherein a transmission bandwidth is in the uplink transmission bandwidth;
the resource group of the reference signal is associated with an uplink transmission bandwidth;
resource configuration information of the reference signal carries information about one or more multi-level bandwidth structures;
configuration information of the resource group of the reference signal carries information about one or more multi-level bandwidth structures; or
configuration information of the resource group of the reference signal carries selection information of multi-level bandwidth structures;
wherein the transmission bandwidth of the reference signal belongs to a bandwidth included in one multi-level bandwidth structure, one bandwidth at an n-th level of the multi-level bandwidth structure comprises one or more bandwidths at an (n+1)-th level, the resource group of the reference signal comprises the one or more resources of the reference signal, and the selection information of multi-level bandwidth structures indicates that one or more multi-level bandwidth structures are selected from more than one predetermined multi-level bandwidth structure.
