Title:
METHOD FOR TRANSMITTING AND RECEIVING SIGNAL BY IAB NODE, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/031141
Kind Code:
A1
Abstract:
The present disclosure provides a method for receiving an uplink signal by an integrated access and backhaul (IAB) node in a wireless communication system. In particular, the method comprises: obtaining timing information related to an uplink reception timing reference for a distributed unit (DU) of the IAB node; receiving a first uplink signal by the DU of the IAB node on the basis of the timing information; and receiving a downlink signal by a mobile-termination (MT) of the IAB node on the basis of the timing information, or transmitting a second uplink signal, wherein the reception of the first uplink signal by the DU of the IAB node and the reception of the downlink signal by the MT of the IAB node or the transmission of the second uplink signal are performed in the same time resource.
