A method performed by a user equipment (UE) operative for connection to a wireless communication system comprising a Wireless Local Area Network (WLAN) and a radio access network (RAN) for efficient usage of resources in the WLAN and the RAN, the WLAN comprising a WLAN control node and the RAN comprising a RAN control node, the method comprising:

• sending to the RAN control node, signal quality measurements performed by the UE on a downlink (DL) signal received from the WLAN control node;
• sending, to the RAN control node, an identity of the WLAN control node;
• receiving, from the RAN control node, an instruction to send a signal to the WLAN control node, and
• sending, to the WLAN control node, a signal based on the identity of the WLAN control node.

A method performed by a radio access network (RAN) control node in a wireless communication system comprising a Wireless Local Area Network (WLAN) and a RAN comprising the RAN control node, for efficient usage of resources in the WLAN and the RAN, the WLAN comprising a WLAN control node, the method comprising:

• receiving a WLAN MAC-address of a user equipment (UE) connected to the RAN;
• receiving, from the UE, DL signal quality measurements performed on a signal received from the WLAN control node;
• receiving, from the UE, an identity of the WLAN control node;
• sending, to the WLAN control node, the WLAN MAC address of the UE based on the identity of the WLAN control node;
• sending, to the UE, an instruction to send a signal to the WLAN control node;
• determining control information regarding whether or not to grant access for the UE to the WLAN, the control information being based on the received DL signal quality measurement;
• and
• sending the determined control information to the WLAN control node.

A method performed by a Wireless Local Area Network, WLAN control node in a wireless communication system comprising a WLAN having the WLAN control node and a radio access network (RAN) for efficient usage of resources in the WLAN and the RAN, the RAN comprising a RAN control node, the method comprising:

• receiving a signal from the UE;
• performing, uplink (UL) signal quality measurements on the signal received from the UE;
• receiving, from the RAN control node, control information regarding whether or not to grant access for the UE to the WLAN, the control information being based on DL signal quality measurements performed by the UE on the signal transmitted by the WLAN control node;
• and
• selectively granting access to the WLAN for the UE, based on the received control information and the performed UL signal quality measurements.
