고밀도 이기종 네트워크에서 스몰셀 기지국(Small-cell base station, SBS)의 수가 증가하면 매크로 단말(Macrocell user equipment, MUE)의 간섭량도 증가하여 수신 신호대 간섭 및 잡음비(Signal-to-interference a...
고밀도 이기종 네트워크에서 스몰셀 기지국(Small-cell base station, SBS)의 수가 증가하면 매크로 단말(Macrocell user equipment, MUE)의 간섭량도 증가하여 수신 신호대 간섭 및 잡음비(Signal-to-interference and noise ratio, SINR)와 시스템 용량이 감소한다. 따라서, 본 논문에서는 SBS의 수가 증가하여도 MUE의 성능을 보장하기 위한 스몰셀 기반 다중점 협력통신(Cooperative Multi-Point, CoMP) 방법을 제안한다. 제안하는 방법은 MUE가 주어진 SINR 임계값을 만족하기 위해 주변에 위치한 SBS들을 선택하고, 선택된 SBS는 MUE에게 CoMP를 제공하여 성능을 향상시킨다. 시뮬레이션 결과를 통해 제안하는 스몰셀 기반 CoMP 방법이 다른 간섭관리 및 CoMP 방법과 비교해 스몰셀 단말의 성능은 크게 감소되지 않으면서 MUE의 평균 SINR과 시스템 용량이 향상됨을 보인다.

In ultra-dense heterogeneous networks, the amount of interference from small-cell base stations(SBS) to macro-cell user equipments (MUEs) increases significantly as the number of SBSs increases and it causes the MUEs to decrease the signal-to-interference and noise ratio(SINR) and system capacity. In this paper, we propose a small-cell based cooperative multi-point(CoMP) communication scheme that can guarantee the performance of MUEs even when the number of SBSs increases. In the proposed scheme, MUEs first find SBSs that give signal strength equal to or greater than a given SINR threshold and then they are served by different numbers of the selected SBSs using CoMP to improve the performance of MUEs. Simulation results show that the proposed small-cell based CoMP scheme outperforms other interference management or CoMP schemes in terms of the SINR and system capacity of MUEs.
