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…
A Scalable and Energy Efficient IoT System Supported by Cell-Free Massive MIMO
Hangsong Yan, Alexei Ashikhmin, Hong Yang
An IoT (Internet of things) system supports a massive number of IoT devices wirelessly. We show how to use Cell-Free Massive MIMO (multiple-input and multiple-output) to provide a…
Long-term scheduling and power control for wirelessly powered cell-free IoT
Xinhua Wang, Xiaodong Wang, Alexei Ashikhmin
We investigate the long-term scheduling and power control scheme for a wirelessly powered cell-free Internet of Things (IoT) network which consists of distributed access points (AP…
Wirelessly Powered Cell-free IoT: Analysis and Optimization
Xinhua Wang, Alexei Ashikhmin, Xiaodong Wang
In this paper, we propose a wirelessly powered Internet of Things (IoT) system based on the cell-free massive MIMO technology. In such a system, during the downlink phase, the sens…
