Handoff Design in User-Centric Cell-Free Massive MIMO Networks Using DRL
Hussein A. Ammar, Raviraj Adve, Shahram Shahbazpanahi +2
In the user-centric cell-free massive MIMO (UC-mMIMO) network scheme, user mobility necessitates updating the set of serving access points to maintain the user-centric clustering.…
Channel Estimation with Asynchronous Reception for User-Centric Cell-Free MIMO Systems
Xuyang Sun, Hussein A. Ammar, Raviraj Adve +2
The user-centric, cell-free wireless network is a promising next-generation communication system, but signal synchronization issues arise due to distributed access points and lack…
Online Distributed Coordinated Precoding for Virtualized MIMO Networks with Delayed CSI
Juncheng Wang, Ben Liang, Min Dong +2
We consider online wireless network virtualization (WNV) in a multi-cell multiple-input multiple output (MIMO) system with delayed feedback of channel state information (CSI). Mult…
Distributed Resource Allocation Optimization for User-Centric Cell-Free MIMO Networks
Hussein A. Ammar, Raviraj Adve, Shahram Shahbazpanahi +2
We develop two distributed downlink resource allocation algorithms for user-centric, cell-free, spatially-distributed, multiple-input multiple-output (MIMO) networks. In such netwo…
RWP+: A New Random Waypoint Model for High-Speed Mobility
Hussein A. Ammar, Raviraj Adve, Shahram Shahbazpanahi +2
In this letter, we emulate real-world statistics for mobility patterns on road systems. We then propose modifications to the assumptions of the random waypoint (RWP) model to bette…
Downlink Resource Allocation in Multiuser Cell-free MIMO Networks with User-centric Clustering
Hussein A. Ammar, Raviraj Adve, Shahram Shahbazpanahi +2
In this paper, we optimize user scheduling, power allocation and beamforming in distributed multiple-input multiple-output (MIMO) networks implementing user-centric clustering. We…
