Abstract

This letter considers a problem of associating users to small-cell base stations (sBSs) and selecting a set of operating sBSs in a small-cell network to minimize the power consumption. We derive a message passing algorithm to obtain a solution distributively. Simulation results show that the proposed algorithm is superior to the conventional schemes.

본 레터는 매크로-셀 위에 스몰-셀이 중첩된 셀룰러 망에서 전력 소모를 최소화하도록 사용자와 기지국을 연계하고 동작 스몰-셀 기지국을 결정하는 문제를 고려한다. 상기 문제의 해를 분산적으로 구하는 메시지 전달 알고리즘을 유도하고, 모의실험을 통해 기존 방식 대비 제안 알고리즘의 우수성을 보인다.
