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…
User-centric Cell-free Massive MIMO Networks: A Survey of Opportunities, Challenges and Solutions
Hussein A. Ammar, Raviraj Adve, Shahram Shahbazpanahi +2
Densification of network base stations is indispensable to achieve the stringent Quality of Service (QoS) requirements of future mobile networks. However, with a dense deployment o…
Resource Allocation and Scheduling in Non-coherent User-centric Cell-free MIMO
Hussein A. Ammar, Raviraj Adve, Shahram Shahbazpanahi +2
We study the problem of user-scheduling and resource allocation in distributed multi-user, multiple-input multiple-output (MIMO) networks implementing user-centric clustering and n…
