Claim 5:
6. An integrated access and backhaul (IAB) node in in a wireless communication system, the UE comprising:
at least one transceiver;
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
receiving, from a parent node, information about a timing offset;
calculating a time difference between a downlink transmission timing from the parent node and a downlink reception timing by the TAB node based on a timing advance (TA) for an uplink transmission to the parent node and the timing offset;
determining a downlink transmission timing to a child node using the time difference; and
transmitting a downlink signal based on the downlink transmission timing.
