A method for uplink and downlink joint dynamic resource allocation for a 6G fully decoupled network. 1) The uplink base station collects channel estimations of the entire network, including pilot signals sent by users and channel estimations made by users based on pilot signals of the downlink base station, and transmits the channel information of the entire network back to the edge center for dynamic resource allocation. 2) According to the channel information between users and uplink / downlink base stations and different sub-channels, assuming that the base station and users adopt the method of equal power sharing, the three-dimensional matching problem of user-base station-sub-channel is modeled as a large-scale many-to-many matching model. 3) According to the matching relationship of user-base station-sub-channel, based on the theory of successive convex approximation, for the uplink coherent transmission of multiple users and the downlink coherent transmission of multiple base stations respectively, an uplink and downlink power control algorithm is adopted. 4) Steps 2 and 3 are both calculated in parallel to obtain the uplink and downlink spectrum division ratio that maximizes the system capacity, and the dynamic resource allocation scheme is sent to the uplink users and downlink base stations for implementation.
