Abstract: Antenna elements support RF communication over a communication link using frequency channels, RF processing circuits, and configuration circuitry to apply a selected configuration. Each configuration identifies processing circuit to antenna element couplings, and which frequency channel is allocated to each RF processing circuit. A reinforcement learning process is applied to dynamically alter which configuration to apply as a currently selected configuration. The reinforcement learning process maintains a future rewards record having entries that maintain, for an associated combination of link state and configuration, an estimated future rewards indication determined using a discounted rewards mechanism. A selection policy selects a configuration for a current link state, and then a new reward is observed that is dependent on how the selected configuration alters a chosen performance metric for the communication link.
