1. A method performed by a Central Unit (CU) of a Radio Access Network (RAN) node in a wireless communication system, the method comprising,
receiving, from a Core Network (CN) node, a first message including first information related to a downlink (DL) data, wherein the DL data is to be transmitted to a wireless device;
transmitting, to a Distributed Unit (DU) of the RAN node, a second message including an indication of an MT-EDT procedure;
receiving, from the DU of the RAN node, second information related to a transport block used for the wireless device;
deciding a Radio Resource Control (RRC) state for transmitting the DL data to the wireless device based on the first information related to the DL data and the second information related to the transport block;
generating a third message based on the decided RRC state; and
transmitting, to the DU of the RAN node, the generated third message.
