5. The method of claim 1 , wherein the transmitting comprises transmitting the one or more measurement results through the RRC signaling.
6. The method of claim 1 , further comprising generating a measurement report having the one or more measurement results, the measurement report including one or more cross-link interference levels that are associated with the IAB DN or the one or more neighboring IAB nodes.
7. The method of claim 1 , wherein the transmitting comprises transmitting the one or more measurement results to a central node within the IAB DN.

a memory to store configuration information with respect to a plurality of reference signals of an integrated access backhaul (IAB) donor node (DN) or one or more neighboring IAB nodes; and
a processor, coupled with the memory, configured to:
receive data from a downlink (DL) transmission or an uplink (UL) transmission,
perform one or more measurements based on the plurality of reference signals of the IAB DN or the one or more neighboring IAB nodes while receiving the data, and
transmit one or more measurement results of the one or more measurements to the IAB node.
9. The apparatus of claim 8 , wherein the processor is configured to receive the data from a IAB DN DL transmission or a child node UL transmission.
