Disclosed is an electronic device including at least one processor, and at least one memory operatively connected with the at least one processor, wherein the at least one memory stores instructions, which when executed, instruct the at least one processor to receive, on a control channel, a control channel message, receive a set of reference signals (RSs) in which each RS corresponds to a beam direction, decode the control channel message to obtain a list of transmission state indicator (TCI) state information for one or more slots, wherein each TCI state information comprises a channel occupancy time (COT) duration indicator for each of the slots, and determine, based on the TCI state information list, whether each RS of the set is valid.
