안테나 그룹핑을 이용한 대규모 다중사용자 다중안테나 시스템 개발

초록

Massive multipe-input multiple-output (MIMO) systems have been studied actively for beyond-4G systems because of their tremendous energy and spectral efficiency. However TDD systems have been primarily studied because the feedback overhead is very large in massive MIMO systems with FDD. In this paper, we proposed an efficient resource allocation strategy for multiuser massive MIMO systems with FDD using antenna grouping and user scheduling techniques.
