1. A method for provisioning signaling in an Integrated Access and Backhaul (IAB) network, comprising:
configuring, by a central unit (CU) of a donor node, a plurality of search spaces (SS) and a number of physical downlink control channel (PDCCH) candidates for each aggregation level (AL) in every SS of the plurality of SS at a mobile terminal (MT) of the child IAB node;
configuring, by at least one of a distributed unit (DU) of a parent IAB node and the CU of the donor node, a scaling factor to the MT of the child IAB node;
scaling, by the MT of the child IAB node, the number of PDCCH candidates for each of the AL in the every SS of the plurality of SS based on the scaling factor; and
performing, by the MT of the child IAB node, the blind decoding of at least one Downlink Control Information (DCI) using the number of scaled PDCCH candidates for each of the AL in every SS of the plurality of SS.
