摘要：
According to some embodiments, a method is performed by an integrated access and backhaul (IAB) node in dual connectivity where an IAB-MT is connected to two IAB parents and two IAB donors. The method comprises: obtaining (1212) a semi-static flexible resource configuration from an IAB donor; obtaining (1214) a first uplink/downlink resource indication for a semi-statically configured flexible resource from a first IAB parent and a second uplink/downlink resource indication from a second IAB parent; obtaining (1216) a priority associated with the first IAB parent and a priority associated with the second IAB parent; determining (1218) the first and second uplink/downlink resource indications conflict; selecting (1220) one of the first and second uplink/downlink resource indications based on the priority associated with the first and second IAB parents; and communicating (1222) with the two IAB parents according to the selected uplink/downlink resource indication.
