초록

We propose a fully distributed and scalable subchannel allocation scheme for cell-free massive MIMO (CF-mMIMO) systems. To effectively mitigate inter-user interference, the proposed method leverages only large-scale fading coefficients, enabling each access point (AP) to perform distributed resource allocation without centralized control. This approach significantly reduces signaling overhead and enhances scalability. Simulations demonstrate that our scheme increases the average downlink data rate by up to 36.17% compared to conventional single-resource systems, validating its high efficiency and low complexity.
