Abstract
An aggregation unit includes a transceiver configured to transmit unique signals to a plurality of transmission reception points (TRxPs) for transmission by the plurality of TRxPs and receive uplink signals received by the plurality of TRxPs from a user equipment. The aggregation unit also includes a processor configured to generate a sum of the uplink signals from a subset of the plurality of TRxPs. The subset is determined based on measurements of the unique signals performed by the UE. In some cases, the subset is determined by a baseband unit that receives a measurement report including the measurements performed by the UE. The transceiver is configured to transmit the sum of the uplink signals to the baseband unit over a fronthaul link.
