The invention provides a cooperative resource limitation based dynamic clustering method and device, and relates to the field of communication. The cooperative resource limitation based dynamic clustering method comprises the steps of storing users with transmission speeds lower than a transmission speed threshold to a to-be-cooperated user set; selecting a to-be-cooperated user with the lowest non-cooperative transmission speed sequentially, and selecting a service base station device of an interference user with the strongest interference channel intensity according to the size upper limit of a cooperation cluster to form a biggest cooperation cluster; when the cooperative transmission speed of the biggest cluster meets the speed threshold, adding the service base station device of the interference user with the strongest interference channel intensity in a pre-sorted cluster into the cooperation cluster sequentially within the number limitation of cooperation participated by the base station device until the cooperative transmission speed meets the transmission speed threshold; otherwise, designing the cooperation cluster based on the interference channel intensity in all the cells. While guaranteeing the requirement on the cooperative transmission speed, the cooperation ability of edge user devices is ensured by using the moderate computational complexity and the cost performance with the maximum cooperative resource utilization, and overweight cooperation burden for a single base station device is avoided.
