본 문서에서는 기지국(BS) 대규모 MIMO(다중 입력 다중 출력) 안테나, 빔 형성 및 추적, BBU(기저대역 내 장치) 핸드오버(HO), 커버리지 등 다양한 핵심 5G 기술을 평가합니다. 이는 실내 사무실 건물 로비, 실외 주차장, 5G 시험 지역을 구축하기 위해 건물에 설치된 BS를 갖춘 5G 무선 액세스 시스템의 현실적인 도시 구축과 같은 다양한 무선 조건을 갖춘 다양한 흥미로운 5G 지역에서 수행됩니다. 도쿄 오다이바 워터프론트 지역. 실험 결과, 10개의 컴포넌트 캐리어를 사용하여 730MHz 대역폭에서 8Gbps를 초과하는 처리량이 달성되었으며, 60개의 RU(Radio Unit)를 사용하여 실내 사무실 건물 로비 및 실외 주차장의 다양한 전송 지점 배포에서 분산 MIMO 처리량 이득이 달성되는 것으로 나타났습니다. 특히, 실외 주차 공간에서는 분산 MIMO와는 뚜렷한 이점이 있을 것으로 예상되며, 분산 MIMO 처리량의 1.5% 증가를 달성합니다. 실험 결과는 또한 도시 배치에서의 다운링크 성능을 명확히 합니다. 실험 결과, 해당 지역에서는 200Gbps 이상의 처리량을 보이고, 기지국으로부터 500m 떨어진 곳에서는 약 28Mbps를 달성하는 것으로 나타났다. 또한 빔 추적 및 BBU 내부 HO가 500GHz에서 높은 경로 손실을 잘 보상하고 BS에서 5m 범위를 달성한다는 것을 확인했습니다. 반면, 28GHz 대역에서는 LoS(가시선) 및 N-LoS(비시선) 조건이 5G 성능에 매우 중요하며, XNUMXG 연결이 때때로 나무, 건물, 건물 뒤에 끊기는 현상이 관찰됩니다. 그리고 인도교 아래.

Abstract: This paper evaluates a variety of key 5G technologies such as base station (BS) massive multiple-input multiple-output (MIMO) antennas, beamforming and tracking, intra-baseband unit (BBU) hand over (HO), and coverage. This is done in different interesting 5G areas with a variety of radio conditions such as an indoor office building lobby, an outdoor parking area, and a realistic urban deployment of a 5G radio access system with BSs installed in buildings to deploy a 5G trial area in the Tokyo Odaiba waterfront area. Experimental results show that throughput exceeding 10Gbps is achieved in a 730MHz bandwidth using 8 component carriers, and distributed MIMO throughput gain is achieved in various transmission point deployments in the indoor office building lobby and outdoor parking area using two radio units (RUs). In particular, in the outdoor parking area, a distinct advantage from distributed MIMO is expected and the distributed MIMO gain in throughput of 60% is achieved. The experimental results also clarify the downlink performance in an urban deployment. The experimental results show that throughput exceeding 1.5Gbps is achieved in the area and approximately 200 Mbps is achieved at 500m away from the BS. We also confirm that the beam tracking and intra-BBU HO work well compensating for high path loss at 28-GHz, and achieve coverage 500m from the BS. On the other hand, line of sight (LoS) and non-line-of sight (N-LoS) conditions are critical to 5G performance in the 28-GHz band, and we observe that 5G connections are sometimes dropped behind trees, buildings, and under footbridges.
