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.…
Handoffs in User-Centric Cell-Free MIMO Networks: A POMDP Framework
Hussein A. Ammar, Raviraj Adve, Shahram Shahbazpanahi +2
We study the problem of managing handoffs (HOs) in user-centric cell-free massive MIMO (UC-mMIMO) networks. Motivated by the importance of controlling the number of HOs and by the…
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…
Hybrid Analog and Digital Beamforming Design for Channel Estimation in Correlated Massive MIMO Systems
Javad Mirzaei, Shahram ShahbazPanahi, Foad Sohrabi +1
In this paper, we study the channel estimation problem in correlated massive multiple-input-multiple-output (MIMO) systems with a reduced number of radio-frequency (RF) chains. Imp…
