Cell-Free Massive MIMO: User-Centric Approach

IEEE Wireless Communications Letters, 2017
Recently, the so-called cell-free (CF) massive MIMO architecture has been introduced, wherein a very large number of distributed access points simultaneously and jointly serve a much smaller number of mobile stations. This letter introduces a user-centric (UC) virtual cell approach to CF massive MIMO, wherein each user is served only by a limited ...

Full-Duplex Cell-Free Massive MIMO

ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019
This work studies a novel full-duplex (FD) cell-free massive multiple-input multiple-output (MIMO) network, where a very large number of multiple-antenna access points (APs) simultaneously serve many single-antenna uplink and downlink users in the same frequency band. The APs operate in the FD mode while the users in the half-duplex (HD) mode.
