Repeater Swarm-Assisted Cellular Systems: Interaction Stability and Performance Analysis
Jianan Bai, Anubhab Chowdhury, Anders Hansson +1
We consider a cellular massive MIMO system where swarms of wireless repeaters are deployed to improve coverage. These repeaters are full-duplex relays with small form factors that…
A Unified Activity Detection Framework for Massive Access: Beyond the Block-Fading Paradigm
Jianan Bai, Erik G. Larsson
The wireless channel changes continuously with time and frequency and the block-fading assumption, which is popular in many theoretical analyses, never holds true in practical scen…
Delay-Constrained Grant-Free Random Access in MIMO Systems: Distributed Pilot Allocation and Power Control
Jianan Bai, Zheng Chen, Erik. G. Larsson
We study a delay-constrained grant-free random access system with a multi-antenna base station. The users randomly generate data packets with expiration deadlines, which are then t…
Robust Covariance-Based Activity Detection for Massive Access
Jianan Bai, Erik G. Larsson
The wireless channel is undergoing continuous changes, and the block-fading assumption, despite its popularity in theoretical contexts, never holds true in practical scenarios. Thi…
Stability Analysis of Interacting Wireless Repeaters
Erik G. Larsson, Jianan Bai
We consider a wireless network with multiple single-antenna repeaters that amplify and instantaneously re-transmit the signals they receive to improve the channel rank and system c…
