1. A first scheduler node of a first cell configured to communicate with a second scheduler node of a second cell, the first scheduler node configured to perform scheduling for a wireless device (WD) in the first cell of a communication system with carrier aggregation, the first scheduler node comprising processing circuitry, the processing circuitry configured to:
receive data to be scheduled for transmission to the WD in the second cell;
transfer the data to the second scheduler node for scheduling transmission of the data in the second cell; and
as a result of the transfer of the data, receive a scheduling decision from the second scheduler node, the received scheduling decision scheduling the transmission of at least a portion of the data to the WD in at least one physical downlink channel in the second cell.
