Abstract
A method for coordinated control-channel signaling by first and second access nodes that provide overlapping coverage on respective first and second carriers that overlap in frequency with each other. The first access node configures a first enhanced physical downlink control channel (ePDCCH) on the first carrier and the second access node configures a second ePDCCH on the second carrier, with the first ePDCCH and second ePDCCH overlapping in frequency and time with each other, for efficient use of PDSCH capacity of the two carriers. In an implementation, the two access nodes could operate according to different radio access technologies. For instance, the first access node could provide LTE service, and the second access node could provide 5G NR service.
