Abstract

Various techniques as described herein coordinate one or more adaptive phase-changing devices, APDs, for communicating with a user equipment, UE. A base station receives (715) a request from a UE to add an additional base station to an active coordination set, ACS, that communicates with the UE using multiple base stations for joint communications. The base station selects (735) selecting a surface configuration for a surface of an APD included in a first communication path between the UE and the first base station or a second communication path between the UE and the additional base station and directs (740) the APD to apply the surface configuration to the surface of the APD. The base station then communicates (745) with the UE as part of the ACS by performing the joint communications with the UE using the APD in the first communication path or the second communication path.
