동기식 TDD(Time Division Duplex) 및 다운링크 데이터 채널에 대한 4×4 단일 사용자 다중 입력 다중 출력(SU-MIMO) 전송에서 수신 전력 및 전송 처리량 특성을 포함한 전송 성능을 단일 사용자와 비교하여 평가했습니다. 우리 대학 연구동 옥상에 로컬 5G 무선 기지국이 설치된 환경에서 SISO(입력 단일 출력) 전송을 수행하는 모습입니다. 따라서 수신전력 특성은 광선추적법을 기반으로 한 시뮬레이션 값과 해당 영역 내 32개 지점에서의 실험값의 차이가 최대 차이 약 10 dB 이내로 충분한 적합성을 얻을 수 있었다. 전송 처리량 대 수신 전력 특성과 관련하여 MIMO에서 처리량 특성을 평가하기 위한 시뮬레이션 방법을 보여준 후 그 결과를 실험 결과와 비교했습니다. 전송 처리량의 CDF(누적 분포 함수)를 보면 SISO 전송에서 CDF 50%에서 시뮬레이션 값은 약 115Mbps, 실험 값은 약 105Mbps 차이 내에서 10Mbps임을 알 수 있습니다. 반면 MIMO 전송에서는 시뮬레이션 값이 380Mbps, 실험값이 약 420Mbps로 약 40Mbps 차이가 난다. 실제 환경에서 Ray Tracing과 MIMO 시뮬레이션 방법을 모두 사용하여 각 수신점에서의 지연 프로파일과 시스템 모델을 획득함으로써 수신 전력 및 전송 처리량 특성을 충분히 정확하게 예측할 수 있음을 보였다.

Abstract: We evaluated the transmission performance, including received power and transmission throughput characteristics, in 4×4 single-user multiple-input multiple-output (SU-MIMO) transmission for synchronous time division duplex (TDD) and downlink data channels in comparison with single-input single-output (SISO) transmission in an environment where a local 5G wireless base station was installed on the roof of a research building at our university. Accordingly, for the received power characteristics, the difference between the simulation value, which was based on the ray tracing method, and the experimental value at 32 points in the area was within a maximum difference of approximately 10 dB, and sufficient compliance was obtained. Regarding the transmission throughput versus received power characteristics, after showing a simulation method for evaluating throughput characteristics in MIMO, we compared the results with experimental results. The cumulative distribution function (CDF) of the transmission throughput shows that, at a CDF of 50%, in SISO transmission, the simulated value is approximately 115Mbps, and the experimental value is 105Mbps, within a difference of approximately 10Mbps. By contrast, in MIMO transmission, the simulation value is 380Mbps, and the experimental value is approximately 420Mbps, which is a difference of approximately 40Mbps. It was shown that the received power and transmission throughput characteristics can be predicted with sufficient accuracy by obtaining the delay profile and the system model at each reception point using the both ray tracing and MIMO simulation methods in actual environments.
