A GNN Approach for Cell-Free Massive MIMO
Lou Salaun, Hong Yang, Shashwat Mishra +1
Beyond 5G wireless technology Cell-Free Massive MIMO (CFmMIMO) downlink relies on carefully designed precoders and power control to attain uniformly high rate coverage. Many such p…
Smart Hybrid Beamforming and Pilot Assignment for 6G Cell-Free Massive MIMO
Carles Diaz-Vilor, Alexei Ashikhmin, Hong Yang
This paper investigates Cell-Free massive MIMO networks, where each access point (AP) is equipped with a hybrid transceiver, reducing the complexity and cost compared to a fully di…
Cell-Free Massive MIMO with Low-Complexity Hybrid Beamforming
Abbas Khalili, Alexei Ashikhmin, Hong Yang
Cell-Free Massive Multiple-input Multiple-output (mMIMO) consists of many access points (APs) in a coverage area that jointly serve the users. These systems can significantly reduc…
Can Massive MIMO Support URLLC?
Hangsong Yan, Alexei Ashikhmin, Hong Yang
We investigate the feasibility of using Massive MIMO to support URLLC in both coherence interval based and 3GPP compliant pilot settings. We consider grant-free uplink transmission…
Optimally Supporting IoT with Cell-Free Massive MIMO
Hangsong Yan, Alexei Ashikhmin, Hong Yang
We study internet of things (IoT) systems supported by cell-free (CF) massive MIMO (mMIMO) with optimal linear channel estimation. For the uplink, we consider optimal linear MIMO r…
Cell-Free Massive MIMO with Nonorthogonal Pilots for Internet of Things
Shilpa Rao, Alexei Ashikhmin, Hong Yang
We consider Internet of Things (IoT) organized on the principles of cell-free massive MIMO. Since the number of things is very large, orthogonal pilots cannot be assigned to all of…
