Energy Efficiency of Wireless Fronthaul Cell-Free mMIMO: A Lamppost-Based Deployment
2025 IEEE 36th International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC)Cell-free massive MIMO (mMIMO) promises to enhance coverage, spectral efficiency, and robustness in dense urban environments by leveraging a distributed approach where multiple access points (APs) cooperate to serve each user. While previous studies have primarily focused on fiber-based fronthaul solutions, wireless fronthaul is gaining traction due to

An efficient algorithm for resource optimization in TWDM passive optical network using a C-RAN
Frontiers in PhysicsThe traditional base station in C-RAN is divided into three parts: a pool of centralized baseband units (BBUs), a fronthaul network that links the BBUs and remote radio units (RRUs), and RRUs.
