A Load Balanced User Association and Resource Allocation Method

Abstract

The invention relates to a load balancing user association and resource allocation method, which belongs to the technical field of communication. This method proposes a load-balanced user association and resource allocation method for the problem that the overall network transmission efficiency is limited due to the unbalanced load in the wireless domain. The main method of the invention includes: designing a user benefit function according to the service quality requirements of different users and the current load of a distributed wireless radio head (Remote Radio Head, RRH). Furthermore, on the premise of ensuring the quality of user service, considering the impact of the current network state on user income, a random game model is established, and user association and resource allocation are performed based on the multi-agent Q learning algorithm, so as to guarantee the user's service quality. Under this condition, the load balancing of the network is realized, and the network throughput is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a user association and resource allocation method for load balancing. Background technique [0002] More and more low-latency intensive tasks, such as real-time communication, high-definition video playback and games, appear in daily life, which greatly increases the bandwidth burden of mobile devices and networks. Different from the traditional Distributed Radio Access Network (D-RAN), the Cloud Radio Access Network (Cloud Radio AccessNetwork, C-RAN) decomposes the traditional base station configuration into a centralized baseband processing unit (Baseband Unite, BBU) and a distributed radio head end (Remote Radio Head, RRH) two parts, and multiple BBUs are concentrated into a BBU pool to achieve statistical multiplexing gain. Dedicated optical fiber as a fronthaul solution for C-RAN will bring huge deployment costs. Time and Wavelength Division Multiplexed Passive Optical...

Problems solved by technology

Although this method is simple, it will cause the problem of RRH load imbalance, resulting in waste of spectrum resources, and ignoring the quality of service (Quality of Service, QoS) requirements of different users

The research on the traffic volume of the wireless network shows that as the load of the RRH increases, the service quality of the users associated with it will decrease.
