Document Type and Number:
WIPO Patent Application WO/2021/086147
Kind Code:
A1
Abstract:
Provided are an operating method for an IAB node including a DU and an MT in a wireless communication system, and a device. The method receives first resource direction information about the DU and second resource direction information about the MT, wherein each of the first and second resource direction information indicates the direction of each resource as being downlink, uplink or flexible. The IAB node determines, for a certain resource from among the resources, whether the DU and the MT can operate at the same time on the basis of the direction indicated by the first resource direction information and the direction indicated by the second resource direction information.
