The study focuses on managing handoffs in user-centric cell-free massive MIMO networks. By formulating a partially observable Markov decision process (POMDP), the authors develop an algorithm to derive a handoff policy for mobile users based on current and future rewards. The approach aims to reduce the complexity of the POMDP by breaking it down into sub-problems, resulting in a significant reduction in the number of handoffs while maintaining service quality. The paper highlights the importance of controlling handoffs in UC-mMIMO networks due to high-speed mobility profiles affecting performance.
