Apparatuses, methods, and systems are disclosed for communicating based on quasi-collocation properties. One method (2300) includes receiving (2302), at a first wireless communication node, a control message from a second wireless communication node. The control message includes a plurality of reference signal indices indicating quasi-collocation properties according to whether a first communication by a first functional entity and a second communication by a second functional entity is restricted based at least in part on the first communication being simultaneous with the second communication. The method (2300) includes determining (2304) whether the second functional entity performs the second communication based in part on the control message.
