Network-Assisted Full-Duplex Cell-Free mmWave Networks: Hybrid MIMO Processing and Multi-Agent DRL-Based Power Allocation

This paper proposes a hybrid MIMO processing framework to eliminate cross-link interference in network-assisted full-duplex (NAFD) cell-free millimeter-wave (mmWave) networks, and develops a collaborative multi-agent deep reinforcement learning (MADRL) algorithm to optimize the bidirectional power allocation.
