Hardware acceleration technique for radio resource scheduling in 5G mobile systems

This article presents a hardware acceleration technique for the scheduling process in ultra-highdensity distributed antenna systems for fifth-generation (5G) mobile communications systems. In 5G systems, the overall system throughputs for a huge number of combinations of antennas and user equipment (UE) for communications have to be calculated in the scheduling process. To speed up the calculation, this acceleration technique calculates the throughputs of each UE simultaneously. Experimental results show that the acceleration technique calculates the system throughput approximately 60 times faster than without the acceleration. As a result, the acceleration technique improved the throughput by about 73% for a system with 32 antennas and 256 UEs. The hardware acceleration technique therefore enables a future practical 5G system.
