Abstract
Network node (110) and method in the network node (110), for forwarding a wirelessly transmitted data packet to a second network node (120), which data packet was received from a third network node (130) with the second network node (120) as the intended recipient. The method comprises monitoring (501) data packets exchanged between the second network node (120) and the third network node (130), determining (502) that a wireless communication session is established between the second and third network nodes (120, 130), measuring (503) received signal power of wireless signals received from the second and third network nodes (120, 130), respectively, on at least two different points in time, detecting (504) a difference over time of measured (503) received signal power, identifying (506) that a data packet, transmitted by the third network node (130) is not received by the second network node (120), forwarding (507) the data packet, identified (506) as not received.
