Claim 11:
12. A non-transitory machine-readable medium storing instructions executable by processing circuitry of 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 execution of the instructions by the processing circuitry causes the node to:
obtain an indication of one of the wireless LC network nodes with which the wireless device has established a wireless LC connection;
obtain 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
determine 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.
