Aerial cuMAC, a Layer 2 MAC scheduler acceleration library, is developed to improve spectral efficiency by introducing a multi-cell scheduler with enhanced algorithms within Layer 2 of the RAN protocol stack. The MAC scheduler, controls how resources are scheduled for all the user equipments (UEs), across all cells, determining the overall spectral efficiency achieved in each cell. cuMAC will provide a net increase in overall performance per watt measured at the cell level, compared to baseline single cell scheduler approaches. NVIDIA is developing cuMAC on the GPU, to bring efficient MAC scheduler implementations to the telco world.
