본 논문에서는 사용자 장비(UE) 그룹화 방식을 제안하고, MIMO(Collaborative Multiple-Input Multiple-Output) 수신에서 형성된 각 그룹에 대한 스케줄링 방식의 성능을 평가한다. 이전 연구에서는 UE 그룹화 기준과 그룹 스케줄링의 효과가 제시된 적이 없다. UE 그룹화 방식에서는 기지국(BS) 중심 기준과 UE 중심 기준 두 가지 기준이 제시된다. BS 중심의 전체 검색 방식은 모든 UE의 상대적 위치에 대한 지식이 필요하지만 이상적인 성능을 달성합니다. 따라서 UE 중심의 지역 탐색 기법도 제안된다. 스케줄링 방식으로는 형성된 각 그룹에 대한 자원할당에 비례형 공정성 스케줄링(Proportional Fairness Scheduling)이 사용된다. 전체 UE 수가 증가하면 그룹 간 UE 수의 차이도 커진다. 컴퓨터 시뮬레이션을 통해 얻은 수치 결과는 기존 방식에 비해 제안 방식이 셀 내 UE 수가 증가할 때 사용자당 처리량이 증가하고 사용자 간 공정성이 감소함을 보여준다.

Abstract: This paper proposes user equipment (UE) grouping schemes and evaluates the performance of a scheduling scheme for each formed group in collaborative multiple-input multiple-output (MIMO) reception. In previous research, the criterion for UE grouping and the effects of group scheduling has never been presented. In the UE grouping scheme, two criteria, the base station (BS)-oriented one and the UE-oriented one, are presented. The BS-oriented full search scheme achieves ideal performance though it requires knowledge of the relative positions of all UEs. Therefore, the UE-oriented local search scheme is also proposed. As the scheduling scheme, proportional fairness scheduling is used in resource allocation for each formed group. When the number of total UEs increases, the difference in the number of UEs among groups enlarges. Numerical results obtained through computer simulation show that the throughput per user increases and the fairness among users decreases when the number of UEs in a cell increases in the proposed schemes compared to those of the conventional scheme.
