산업혁명을 가속화하기 위해 새로운 셀룰러 네트워크 개념은 2010년경 5세대(4G) 이동 무선통신 시스템으로 구체화되기 시작했다. 5세대(5G) 이동통신 시스템인 LTE(Long Term Evolution)와 5G NR(New Radio)의 주요 차이점 중 하나는 활용되는 주파수 대역이다. XNUMXG NR은 더 높은 주파수 대역을 가정합니다. 더 높은 주파수 대역을 효과적으로 활용하려면 더 큰 경로 손실이라는 기술적 문제를 해결해야 합니다. Massive MIMO(Massive MIMO) Beamforming(BF) 기술은 이러한 문제를 극복하는 데 기여하므로 고성능 및 구현의 용이성을 위해서는 주파수 대역별 Massive MIMO BF에 대한 추가 연구가 필요합니다. 본 논문에서는 낮은 초고주파(SHF) 대역 다운링크(DL) 전송을 위한 XNUMX탭 프리코딩 기반의 완전 디지털 BF를 갖춘 Massive MIMO 방법(디지털 FBCP라고 함)을 제안합니다. 또한 다중 사이트 환경을 위한 디지털 FBCP를 위한 세 가지 사이트 간 조정 알고리즘이 제시되고 세 가지 알고리즘 중 하나가 향상됩니다. Digital FBCP는 원탭 프리코딩을 사용하는 기존 알고리즘보다 더 나은 처리량 성능을 달성하는 것으로 나타났습니다. 사이트 간 조정 성능도 고려하면 다양한 실제 환경에서 Digital FBCP가 약 XNUMXGbps를 달성할 수 있다는 결론을 얻었다.

Abstract: Towards furthering the industrial revolution, the concept of a new cellular network began to be drawn up around 2010 as the fifth generation (5G) mobile wireless communication system. One of the main differences between the fourth generation (4G) mobile communication system Long Term Evolution (LTE) and 5G new radio (NR) is the frequency bands utilized. 5G NR assumes higher frequency bands. Effective utilization of the higher frequency bands needs to resolve the technical issue of the larger path-loss. Massive multiple-input multiple-output (Massive MIMO) beamforming (BF) technology contributes to overcome this problem, hence further study of Massive MIMO BF for each frequency band is necessary toward high-performance and easy implementation. In this paper, then, we propose a Massive MIMO method with fully-digital BF based on two-tap precoding for low super high frequency (SHF) band downlink (DL) transmissions (called as Digital FBCP). Additionally, three intersite coordination algorithms for Digital FBCP are presented for multi-site environments and one of the three algorithms is enhanced. It is shown that Digital FBCP achieves better throughput performance than a conventional algorithm with one-tap precoding. Considering performance of intersite coordination as well, it is concluded that Digital FBCP can achieve around 5 Gbps in various practical environments.
