This application provides a distributed wireless resource scheduling method and electronic device, relating to the field of wireless communication network technology. In this method, the coordinator and computing nodes only need one round of information exchange, avoiding the huge signaling overhead and accumulated latency caused by multiple rounds of iterative negotiation. Time-consuming optimization calculations are offloaded to multiple computing units for parallel execution, achieving a linear reduction in overall computation time. Furthermore, it leverages the approximate achievable rate to provide theoretical feasibility for distributed solutions, while global coordination by edge devices ensures the performance of critical users, allowing the performance of the distributed solution to approach that of centralized algorithms, which serve as the performance ceiling. Because the coordination overhead is constant and minimal, and the computational load is effectively distributed, the system performance is far less affected by network size growth than centralized solutions. This makes it highly suitable for deployment in future network scenarios such as ultra-dense networking and large-scale carrier aggregation, enabling high-performance, low-overhead, and scalable distributed resource allocation under an O-RAN architecture.
