Classification: CPC H | IPC H

Claim 0:
1. A method of configuring reference signal channel characteristics, comprising:
receiving, by a second communication node from a first communication node, a radio resource control (RRC) signaling that carries information that describes a first set of transmission configuration indication (TCI) states,
wherein each TCI state in the first set of TCI states comprises one or more index elements that identify one or more reference signals; and

receiving, by the second communication node from the first communication node, a medium access control-control element (MAC-CE) signaling that carries information that indicates that a second set of TCI states are activated,
wherein the second set of TCI states include at least one TCI state that is activated from the first set of TCI states; and

receiving a downlink control information (DCI) signaling sent by the first communication node,
wherein the DCI signaling comprises indication information related to a TCI state from the second set of TCI states, and

wherein the indication information indicates a channel characteristic of a downlink demodulation reference signal (DMRS) and of a channel state information reference signal (CSI-RS), and a channel characteristic assumption of a sounding reference signal (SRS).
