UC-UDN proportional fair resource allocation method in 5G communication system

Abstract

The UC‑UDN proportional fair resource allocation method in the 5G communication system involves 5G wireless communication resource allocation technology. The information exchange pressure of user resource allocation and scheduling, the present invention realizes proportionally fair resource allocation under the UC-UDN network, by setting the weight value of the directed edge in the directed graph, and optimizing the goal of user scheduling in the group Design to achieve proportional fair transmission of users on consecutive time slots in UC‑UDN network.

[0004] figure 2 Given a UDN network model, consider the downlink communication in UDN, which includes densely deployed L base stations (APs) and K users (UEs), which respectively form base stations and user sets L={1,2,... ,L} and K={1,2,...,K}, the number of antennas of the AP is M>1 and the UE adopts a single-antenna configuration. The focus of communication is to design a scheme that can allocate wireless resources proportionally and fairly in consecutive time slots , invented the problem of multi-carrier resource allocation based on the premise that a large number of users are first allocated to each sub-carrier used by the system. The throughput needs to be improved, and the complexity of resource allocation and scheduling in the existing resource allocation and scheduling methods needs to be improved. The information exchange pressure to achieve optimal user resource allocation and scheduling in the network needs to be improved.
