Leveraging Slowly Time-Varying AP-AP Channels for Interference Mitigation in Dynamic TDD
Martin Andersson, Tung T. Vu, Pål Frenger +2
We address the challenge of cross-link interference in dynamic time-division duplexing (TDD) systems. Specifically, we focus on mitigating the interference caused by access points…
A Flexible Framework for Grant-Free Random Access in Cell-Free Massive MIMO Systems
Sai Subramanyam Thoota, Erik G. Larsson
We propose a novel generalized framework for grant-free random-access (GFRA) in cell-free massive multiple input multiple-output systems where multiple geographically separated acc…
Reducing Dynamic Range in Bistatic Backscatter Communication via Beamforming Design
Ahmet Kaplan, Diana P. M. Osorio, Erik G. Larsson
Considering the exponential growth of Internet-of-Things devices and the goals toward sustainable networks, the complexity should be focused on the infrastructure side. For a massi…
Propagation Distance Estimation for Radio over Fiber with Cascaded Structure
Dexin Kong, Diana Pamela Moya Osorio, Erik G. Larsson
Recent developments in polymer microwave fiber (PMF) have opened great opportunities for robust, low-cost, and high-speed sub-terahertz (THz) communications. Noticing this great po…
User-to-User Interference Mitigation in Dynamic TDD MIMO Systems with Multi-Antenna Users
Martin Andersson, Tung T. Vu, Pål Frenger +1
We propose a novel method for user-to-user interference (UUI) mitigation in dynamic time-division duplex multiple-input multiple-output communication systems with multi-antenna use…
Access Point Selection for Bistatic Backscatter Communication in Cell-Free MIMO
Ahmet Kaplan, Diana P. M. Osorio, Erik G. Larsson
Backscatter communication (BC) has emerged as a key technology to satisfy the increasing need for low-cost and green Internet-of-Things (IoT) connectivity, especially in large-scal…
Joint Optimization of Switching Point and Power Control in Dynamic TDD Cell-Free Massive MIMO
Martin Andersson, Tung T. Vu, Pål Frenger +1
We consider a cell-free massive multiple-input multiple-output (CFmMIMO) network operating in dynamic time division duplex (DTDD). The switching point between the uplink (UL) and d…
Reciprocity Calibration of Dual-Antenna Repeaters
Erik G. Larsson, Joao Vieira, Pål Frenger
We present a reciprocity calibration method for dual-antenna repeaters in wireless networks. The method uses bi-directional measurements between two network nodes, A and B, where f…
