Uplink and downlink joint dynamic resource allocation method for 6G full decoupling network

Abstract

An uplink and downlink combined dynamic resource allocation method for a 6G full decoupling network comprises the following steps: 1) an uplink base station collects channel estimation of the whole network, the channel estimation comprises pilot signals sent by a user and channel estimation performed by the user based on pilot signals of a downlink base station, and channel information of the whole network is transmitted back to an edge center for dynamic resource allocation; 2) according to channel information between users and uplink and downlink base stations and between the users and different sub-channels, assuming that the base stations and the users adopt a power sharing method, and modeling a user-base station-sub-channel three-dimensional matching problem into a large-scale many-to-many matching model; (3) according to the user-base station-subchannel matching relation, on the basis of the continuous convex approximation theory, an uplink power control algorithm and a downlink power control algorithm are adopted for uplink coherent transmission of multiple users and downlink coherent transmission of multiple base stations respectively; and 4) carrying out parallel calculation on the steps 2 and 3 to obtain an uplink and downlink spectrum division proportion which enables the system capacity to be maximum, and sending a dynamic resource allocation scheme to an uplink user and a downlink base station to realize the dynamic resource allocation scheme.

Description

technical field [0001] The invention belongs to the field of 6G fully decoupled network resource allocation, and relates to an uplink and downlink joint dynamic resource allocation method for a 6G fully decoupled network. Background technique [0002] With the implementation of my country's "new infrastructure" plan, the fifth-generation mobile communication (5G) has begun to be deployed on a large scale, and the research on the super-fifth-generation mobile communication technology (Beyond 5G, B5G) is also being carried out simultaneously, and the international community has also stepped into 6G. The first year of research and development. Compared with the fourth-generation mobile communication system, the 5G network can provide basic business capabilities that are ubiquitous and connected to everything. my country attaches great importance to the development of 5G / B5G mobile communications. The Ministry of Industry and Information Technology, the Ministry of Science and T...

Problems solved by technology

[0005] To sum up, the problems existing in the existing technology are: (1) The traditional TDD and FDD spectrum allocation methods cannot fully release the spectrum resource utilization potential of the 6G fully decoupled network

(3) The power allocation between users and base stations in uplink and downlink transmission is a non-convex optimization problem, the objective function is the weighted rate of users, and a low-complexity power control algorithm needs to be redesigned
