Abstract: Embodiments of the present disclosure describe devices, methods, computer-readable media, and systems configurations for configuration of downlink coordinated multipoint (CoMP) communications in a wireless communication network. A user equipment (UE) may receive, from an evolved Node B (eNB), a radio resource control (RRC) transmission including channel state informations (CSI) reference signal (RS) parameters for a plurality of transmission points. The UE may subsequently receive a medium access control (MAC) control element (CE) including a plurality of index bits corresponding to one or more activated transmission points of the plurality of transmission points for which the feedback module is to generate CSI-RS feedback. The eNB may dynamically update the transmission points that are activated for CSI-RS feedback. The UE may receive another MAC CE from the eNB to notify the UE of the updated set of activated transmission points.
