Abstract
There is provided a reflection node for handling link failure towards a network node. The reflection node includes a controller for controlling a passive meta-surface having a controllable reflection angle for reflecting radio waves over a communication channel between a network node and a wireless device. The reflection node includes a transceiver unit for receiving instructions from the network node over a control channel. The transceiver unit is configured to determine a link failure event on the control channel between the reflection node and the network node. The controller is configured to, during the link failure event, control the reflection angle of the passive meta-surface using reflection settings specified by configuration data for reflecting the radio waves over the communication channel.
