Joint optimal beamforming and power control in cell-free massive MIMO
Lorenzo Miretti, Renato Luis Garrido Cavalcante, Slawomir Stanczak
We derive a fast and optimal algorithm for solving practical weighted max-min SINR problems in cell-free massive MIMO networks. For the first time, the optimization problem jointly…
A Learning-Based Approach to Approximate Coded Computation
Navneet Agrawal, Yuqin Qiu, Matthias Frey +4
Lagrange coded computation (LCC) is essential to solving problems about matrix polynomials in a coded distributed fashion; nevertheless, it can only solve the problems that are rep…
Closed-form max-min power control for some cellular and cell-free massive MIMO networks
Lorenzo Miretti, Renato L. G. Cavalcante, Slawomir Stanczak +3
Many common instances of power control problems for cellular and cell-free massive MIMO networks can be interpreted as max-min utility optimization problems involving affine interf…
Robust Cell-Load Learning with a Small Sample Set
Daniyal Amir Awan, Renato L. G. Cavalcante, Slawomir Stanczak
Learning of the cell-load in radio access networks (RANs) has to be performed within a short time period. Therefore, we propose a learning framework that is robust against uncertai…
Set-Theoretic Learning for Detection in Cell-Less C-RAN Systems
Daniyal Amir Awan, Renato L. G. Cavalcante, Zoran Utkovski +1
Cloud-radio access network (C-RAN) can enable cell-less operation by connecting distributed remote radio heads (RRHs) via fronthaul links to a powerful central unit. In conventiona…
Joint Source-Channel Coding for Semantics-Aware Grant-Free Radio Access in IoT Fog Networks
Johannes Dommel, Zoran Utkovski, Osvaldo Simeone +1
A fog-radio access network (F-RAN) architecture is studied for an Internet-of-Things (IoT) system in which wireless sensors monitor a number of multi-valued events and transmit in…
