1. A method performed by a node of a wireless communication network that includes a wireless device, a radio access network node and one or more wireless light communication (LC) network nodes, wherein at least one of the wireless device and the radio access network node comprises a plurality of antenna elements configurable to provide a transmit or receive radio beam for communication with the other of the wireless device and the radio access network node, wherein the method comprises:
obtaining an indication of one of the wireless LC network nodes with which the wireless device has established a wireless LC connection;
obtaining one or more first signal metrics for respective one or more first transmit or receive radio beams directed according to one of the following: towards a coverage area of the indicated wireless LC network node, or to receive transmissions from the coverage area of the indicated wireless LC network node; and
determining whether or not a particular one of the first transmit or receive radio beams corresponds to a line-of-sight (LoS) between the radio access network node and the wireless device, based on a comparison between the first signal metric for the particular first transmit or receive radio beam and a first threshold.
