1. A method performed by a network node of a wireless communication network, the method comprising, in each control cycle in a continuing succession of control cycles, performing control operations including:
obtaining estimates of application-layer availability and reliability for respective devices among a population of devices collectively operating as a cyber-physical system, each device executing one or more respective applications that run in dependence on cyber-physical system communications exchanged over a respective wireless link provided by the wireless communication network, such that the estimates of application-layer availability and reliability depend on channel conditions of the respective wireless links and loading conditions in the wireless communication network, bearing on delivery of the cyber-physical system communications;
determining a set of control decisions via a learned reward function that takes the estimates of application-layer availability and reliability as inputs and is trained to determine the set of control decisions as transmit power and transmit diversity settings for transmitting on the respective wireless links, for maximization of application-layer availability and reliability in the cyber-physical system, subject to transmit power and bandwidth allocations of the wireless communication network for supporting the cyber-physical system; and
sending signaling indicating the transmit power and transmit diversity settings.
