Abstract
The capability of massive multiple-input multipleoutput (mMIMO) systems supporting the throughput requirement of as many users as possible is investigated. The bottleneck
of serving small numbers of users by a large number of
transmit antennas in conventional mMIMO is unblocked by a
new time-fraction-wise beamforming technique, which focuses
signal transmission in fractions of a time slot. Based on this timefraction-wise signal transmission, a new user service scheduling
for multi-cell mMIMO, whose cell-edge users suffer not only poor
channel conditions but also multi-cell interference, is proposed
to support a large user-population. We demonstrate that the
numbers of users served by our multi-cell mMIMO within a
time-slot may be as high as twice the number of its transmit
antennas.
