1. A method implemented in a network node, the method comprising:
determining information concerning at least one of: (i) an impairment of a first signal from a first integrated access backhaul, (IAB) node that is caused by a second signal from a second IAB node and (ii) an impairment of the second signal that is caused by the first signal;
selecting a multiplexing capability for the network node based at least in part on the determined information concerning at least one of the impairments; and
multiplexing signals for the first and second IAB nodes using the selected multiplexing capability;
receiving requirement information prior to receiving the first signal from the first IAB node, the requirement information comprising information concerning at least one of: an interference level threshold, a backhaul link minimum data rate, and a link reliability;
determining a transmit power relation based at least in part on a cross link interference (CLI) threshold, wherein the transmit power relation that is based at least in part on the CLI threshold is at least one of a minimum power relation and a maximum power relation; and
transmitting the transmit power relation to at least one of the first and second IAB nodes, wherein the first IAB node is one of a wireless device (WD), a parent IAB node and a child IAB node to the network node, and the second IAB node is another one of the WD, the parent IAB node and the child IAB node.
