1. A method performed by a base station for communicating with a user equipment (UE) using multiple adaptive phase-changing devices (APDs) the method comprising:
establishing a wireless connection with the UE;
determining, based on the wireless connection, to include at least a first adaptive phase-changing device (APD) and a second APD in a wireless communication path with the UE;
determining a first surface configuration for a first surface of the first APD and a second surface configuration for a second surface of the second APD;
transmitting an indication of the first surface configuration to the first APD over an APD physical downlink control channel (APD-PDCCH) to dynamically configure the first APD on a slot-by-slot basis by directing the first APD to apply the first surface configuration to the first surface based on first timing information;
directing the second APD to apply the second surface configuration to the second surface based on second timing information; and
communicating with the UE using wireless transmissions that travel along the wireless communication path that includes the first surface of the first APD and the second surface of the second APD.
