1. A system to provide wireless service comprising:
a base band unit; and
a plurality of antennas communicatively coupled to the base band unit;
wherein the base band unit and the plurality of antennas are configured to implement a base station in order to provide wireless service to a plurality of user equipment (UEs) using a cell;
wherein the system is configured for frequency reuse implemented via the plurality of antennas in order to transmit to subsets of the UEs, wherein the UEs included in each subset are transmitted respectively different data using the same resource elements;
wherein 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;
wherein 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; and
wherein the system is configured to use the base station data to determine the candidate UEs for transmission to using frequency reuse by using at least some of the HARQ ACK/NACK data for the plurality of UEs included in the base station data to determine the candidate UEs for transmission to using frequency reuse.
