Abstract
One embodiment is directed to a system to provide wireless service comprising a base band unit and a plurality of antennas communicatively coupled to the base band unit. The system is configured for frequency reuse implemented via the plurality of antennas in order to transmit to subsets of the UEs. The UEs included in each subset are transmitted respectively different data using the same resource elements. The system is configured to collect base station data including Channel Quality Information (CQI) data, Sounding Reference Signal (SRS) data, and hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) data for the plurality of UEs. The system is configured to use the base station data to determine candidate UEs for transmission to using frequency reuse and to determine modulation and coding schemes (MCSs) for the UEs transmitted to using frequency reuse.
