13. A method of wireless communication performed by a wireless node, comprising:
receiving a reference signal (RS) configuration that indicates a first RS resource set and a second RS resource set for transmission of RS, wherein the first RS resource set is included in a first group of RS resource sets to be used by multiple wireless nodes of a base station to transmit RSs, and wherein the second RS resource set is included in a second group of RS resource sets to be used by a subset of the multiple wireless nodes to transmit RSs;
transmitting a first RS on the first RS resource set; and
transmitting a second RS on the second RS resource set,
wherein a hierarchical relationship between the first RS resource set and the second RS resource set are indicated in the RS configuration signaled to the wireless node.
