Abstract

The present invention provides a resource allocation method for an LTE network, comprising the following steps: obtaining cell users and LTE network parameters that need resource allocation, and establishing a mathematical model for LTE network uplink resource allocation according to a single-objective multi-constraint programming method; through iterative optimization The method converts the combined optimization solution of the mathematical model into a knapsack problem; converts solving the multi-choice knapsack problem into solving a multi-stage decision-making process diagram according to the dynamic programming method; solves the multi-stage decision-making process according to the preset improved Dijkstra algorithm , to obtain the uplink resource allocation results of each user. The invention also provides a corresponding system, which can significantly reduce the complexity of resource allocation and achieve the most appropriate allocation of resources.

Description

technical field [0001] The present invention relates to the field of LTE network technology, in particular to a resource allocation method for an LTE network and a resource allocation system for an LTE network. Background technique [0002] With the development of wireless mobile communication, from the original 2G technology to the application of 3G technology, to the research of B3G (Beyond3rd Generation) technology and HSDPA (High Speed ​​Downlink Packet Access) technology, until now the most concerned Research on LTE (Long-Term-Evolution) technology is accompanied by further development and in-depth research on wireless resource allocation technology. Future broadband wireless communication is aimed at high transmission rate, low bit error rate, low power consumption, more users sharing spectrum and more convenient communication anytime and anywhere. Every revolution of wireless mobile communication technology directly promotes the development of wireless spectrum resour...
