| Abstract(in English) | For the fifth generation mobile communication systems (5G), in order to increase overall system throughput, ultra-high-density distributed antenna systems have been studied. Resource scheduling controls radio transmission of all antennas in the system. The scheduling searches for the suitable combination of antennas and user equipment from a huge number of passible combinations within the limited scheduling period. In order to test more combinations, we devised a novel scheduler that accelerates the scheduling process and improves the combination until the scheduling period expired. Experimental results show that the scheduler performs the calculation of the system throughput 60 times faster than software-based processing. Simulation results show that the scheduler can improve the system throughput by approximately 13%. Furthermore, we devised two architectures of scheduler with a hardware accelerator and clarified the advantages of them. These techniques enable a future practical 5G system. |
