1. A method for allocating resources of an integrated access and backhaul (IAB) node supporting space division multiplexing/spatial multiplexing (SDM), comprising:
receiving a radio resource control (RRC) signal for a cell-specific semi-static configuration of a mobile terminal (MT)/user equipment (UE) of the IAB node and a distributed unit (DU) of the LAB node, wherein the RRC signal comprises a TDD-UL-DL-ConfigCommon signal that includes 4 patterns for cell-specific assignment, wherein the 4 patterns comprise 2 cell-specific uplink (UL)-Flexible (F)-downlink (DL) patterns, wherein the TDD-UL-DL-ConfigCommon signal comprises a TDD-UL-DL-Pattern2 that defines a cell-specific UL-F-DL pattern of the 2 cell-specific UL-F-DL patterns;
allocating, for the MT/UE of the IAB node, a first pattern of the 4 patterns;
allocating, for the DU of the IAB node, the cell-specific UL-F-DL pattern that is a reverse pattern of the first pattern; and
communicating with a child IAB node, using the cell-specific UL-F-DL pattern.
