Abstract: Systems, methods, apparatuses, and computer program products for the synchronization and timing of IAB nodes are provided. One method may include determining, at a parent node, a resource configuration and using the determined resource configuration to set a timing advance (TA) mode with two offsets comprising a first offset to be used with time division multiplexing (TDM) and a second offset to be used with at least one of spatial division multiplexing (SDM) or frequency division multiplexing (FDM). The method may also include transmitting a command, to an integrated access and backhaul (IAB) node, to start adjusting mobile termination (MT) uplink (UL) transmission (Tx) timing based on the resource configuration and the timing advance (TA).
