| Summary: | Cell-Free Massive MIMO is a promising technology which many access points
cooperate to jointly serve UEs within the same time-frequency resource. However,
the original form of Cell-Free Massive MIMO is not scalable when the number of
UEs goes to infinity. Clustering is one of the solutions to make Cell-Free Massive
MIMO systems becomes scalable where each AP only serves a subset of UEs with
the best channel. In this paper, we propose a framework to form clusters between
UE and APs and pilot assignment that takes the maximum number of UEs that can
be served by each AP into consideration. The proposed algorithm outperforms
benchmark algorithm in terms of 95%-likely per-user SE when the number of UEs
is massive.
