Abstract
(EN)
According an embodiment of the present disclosure, provided is an IAB node in a wireless communication system which: receives downlink (DL) flow control setting information; reports DL flow control feedback information to an IAB parent node on the basis of at least one among the format of the DL flow control feedback information as determined from the received DL flow control setting information, the report granularity of the DL flow control feedback information, the data amount of the DL flow control feedback information, the data type of the DL flow control feedback information, and the reporting conditions of the DL flow control feedback information; and receives, from the IAB parent node, data scheduled on the basis of the DL flow feedback information.
