A system and method (40, 50, 70, 80) for meeting a pre-defined requirement for uplink (UL) measurements when low-activity state configuration, and for allowing a node to adapt or adjust the UL signals, is disclosed. Particularly, a measuring node (30a) is configured to adapt its UL measurements responsive to obtaining information about low-activity state configuration of a transmitting node. The transmitting node (30b) is configured to adapt its UL transmission when configuring low-activity states to comply with the pre-defined requirement or rule. A configuring node (30c) initiates configuring the UL radio signal transmissions for the transmitting node, and adaptively configures the low-activity state configuration and/or the UL radio signal configuration for the transmitting node.
