초록

본 논문에서는 클러스터 이기종 셀룰러 네트워크에서 반동적 셀 그룹핑을 위한 합동 셀 그룹핑 및 사용자 접속 기법을 제안한다. 최근에는 핫스팟에서의 폭발적인 데이터 요구량을 지원하기 위해서, 소형 셀들이 기존의 매크로 기지국들과 함께 설치되고 있다. 이러한 클러스터 이기종 셀룰러 네트워크에서는 간섭과 부하 불균형으로 인하여 성능 열화가 발생할 수 있다. 본 논문에서 제안하는 기법은 사용자들의 비례공평이 최대화되도록 두 가지 문제를 합동적으로 다룬다. 모의실험을 통하여, 기존의 기법들보다 제안하는 기법을 통해 훨씬 더 향상된 사용자 평균 전송률 및 사용자간의 비례공평을 얻을 수 있음을 알아본다.

In this paper, a joint cell grouping and user association technique proposed for a semi-dynamic grouped network MIMO in a clustered heterogeneous cellular network (HCN). With the conventional macro BSs, small cells are being overlaid to increase a spectral efficiency per area and these small cells are expected to be concentrated to support exponentially increasing data traffic in hot spot areas. The main culprits of performance degradation in the clustered HCN are interference and load imbalance. The proposed scheme jointly handles them to maximize a proportional-fair metric. It is shown that the proposed technique can largely improve user average rate and proportional fairness among users than any other conventional schemes in the clustered HCN.
