In a first aspect, configuring the indication that transmissions of the MT of the IAB node can be used for CLI measurement of the DU of the IAB node comprises configuring an indication that the DU of the IAB node and the MT of the IAB node share a same RF architecture, wherein the indication that the DU of the IAB node and the MT of the first IAB node share the same RF architecture implicitly indicates that transmissions of the MT of the IAB node can be used for CLI measurement of the DU of the IAB node. In a second aspect, alone or in combination with the first aspect, configuring the indication that transmissions of the MT of the IAB node can be used for CLI measurement of the DU of the IAB node comprises configuring a 1-bit indicator to explicitly indicate that transmissions of the MT of the IAB node can be used for CLI measurement of the DU of the IAB node.
In a third aspect, alone or in combination with one or more of the first and second aspects, configuring the indication that transmissions of the MT of the IAB node can be used for CLI measurement of the DU of the IAB node comprises configuring an indication of one or more cell identifiers associated with the DU of the IAB node for which transmissions of the MT of the IAB node can be used for CLI measurement of the DU of the IAB node. In a fourth aspect, alone or in combination with one or more of the first through third aspects, configuring the indication that transmissions of the MT of the IAB node can be used for CLI measurement of the DU of the IAB node comprises configuring an indication of at least one of one or more beam directions supported by the MT of the IAB node or one or more frequency bands supported by the MT of the IAB node.
