Generalized Reduced-WMMSE Approach for Cell-Free Massive MIMO With Per-AP Power Constraints
Wonsik Yoo, Daesung Yu, Hoon Lee +1
The optimization of cooperative beamforming vectors in cell-free massive MIMO (mMIMO) systems is presented where multi-antenna access points (APs) support downlink data transmissio…
Learning Decentralized Power Control in Cell-Free Massive MIMO Networks
Daesung Yu, Hoon Lee, Seung-Eun Hong +1
This paper studies learning-based decentralized power control methods for cell-free massive multiple-input multiple-output (MIMO) systems where a central processor (CP) controls ac…
Robust Design of Rate-Splitting Multiple Access With Imperfect CSI for Cell-Free MIMO Systems
Daesung Yu, Seok-Hwan Park, Osvaldo Simeone +1
Rate-Splitting Multiple Access (RSMA) for multi-user downlink operates by splitting the message for each user equipment (UE) into a private message and a set of common messages, wh…
Deep Learning Methods for Joint Optimization of Beamforming and Fronthaul Quantization in Cloud Radio Access Networks
Daesung Yu, Hoon Lee, Seok-Hwan Park +1
Cooperative beamforming across access points (APs) and fronthaul quantization strategies are essential for cloud radio access network (C-RAN) systems. The nonconvexity of the C-RAN…
Optimizing Over-the-Air Computation in IRS-Aided C-RAN Systems
Daesung Yu, Seok-Hwan Park, Osvaldo Simeone +1
Over-the-air computation (AirComp) is an efficient solution to enable federated learning on wireless channels. AirComp assumes that the wireless channels from different devices can…
Inter-Tenant Cooperative Reception for C-RAN Systems With Spectrum Pooling
Junbeom Kim, Daesung Yu, Seok-Hwan Park +2
This work studies the uplink of a multi-tenant cloud radio access network (C-RAN) system with spectrum pooling. In the system, each operator has a cloud processor (CP) connected to…
