This paper presents a high-speed radio-resource scheduler that accelerates the scheduling process of fifth-generation mobile communications systems (5G). A scheduler for 5G systems will have to decide the optimal combination of an antenna and user equipment for efficient communications from a huge number of possible combinations. The reported scheduler with a hardware accelerator performs several high-speed searches to find the optimal combination. Experimental results show that it executes several search methods 40 times faster than a scheduler without acceleration. It improves the system throughput and will enable a practical 5G system to be developed.
