Optimal Design of Energy-Efficient Cell-Free Massive MIMO: Joint Power Allocation and Load Balancing
Trinh Van Chien, Emil Björnson, Erik G. Larsson
A large-scale distributed antenna system that serves the users by coherent joint transmission is called Cell-free Massive MIMO (multiple input multiple output). For a given user se…
Dynamic Resource Allocation in Co-Located and Cell-Free Massive MIMO
Zheng Chen, Emil Björnson, Erik G. Larsson
In this paper, we study joint power control and scheduling in uplink massive multiple-input multiple-output (MIMO) systems with randomly arriving data traffic. We consider both co-…
Joint Unicast and Multi-group Multicast Transmission in Massive MIMO Systems
Meysam Sadeghi, Emil Björnson, Erik G. Larsson +2
We study the joint unicast and multi-group multicast transmission in massive multiple-input-multiple-output (MIMO) systems. We consider a system model that accounts for channel est…
Optimizing Information Freshness in a Multiple Access Channel with Heterogeneous Devices
Zheng Chen, Nikolaos Pappas, Emil Björnson +1
In this work, we study age-optimal scheduling with stability constraints in a multiple access channel with two heterogeneous source nodes transmitting to a common destination. The…
Local Partial Zero-Forcing Precoding for Cell-Free Massive MIMO
Giovanni Interdonato, Marcus Karlsson, Emil Björnson +1
Cell-free Massive MIMO (multiple-input multiple-output) is a promising distributed network architecture for 5G-and-beyond systems. It guarantees ubiquitous coverage at high spectra…
Multi-Tag Backscattering to MIMO Reader: Channel Estimation and Throughput Fairness
Deepak Mishra, Erik G. Larsson
Green low power networking with the least requirement of dedicated radio resources is need of the hour which has led to the upsurge of backscatter communication (BSC) technology. H…
