Cell-free massive MIMO technology offers significant benefits for next-generation communication systems. The proposed partially coherent transmission framework optimizes AP clustering, combining at UEs, and precoding at APs to enhance network performance. By addressing phase misalignment challenges, the PC operation shows promising results in practical deployments of cell-free massive MIMO networks.
Statisztikák
Cell-free massive multiple-input multiple-output (MIMO) is a promising technology for next-generation communication systems.
The proposed framework with a sufficiently small reference distance can offer a sum rate close to the ideal fully coherent operation.
The PC operation does not require network-wide synchronization, making it feasible for future communication systems.
Numerical results demonstrate the potential of the PC operation in practical deployments of cell-free massive MIMO networks.
