基于分QCI承载预调度的TD-LTE上行资源受限优化方法

An optimization method for constrained TD-LTE uplink resource based on sub-QCI bearer pre-scheduling

通过对TD-LTE上行PRB资源的组成研究及资源占用情况分析,目前TD-LTE网络上行PRB资源很大一部分用于预调度开销。根据对预调度机制以及算法的研究,本文提出分QCI承载预调度的TD-LTE上行资源受限优化方法,同时结合网络感知对优化结果进行分析,得出方案适用范围,在确保用户感知的前提下降低网络负荷。

Based on the analysis of the composition of TD-LTE uplink PRB resources and the analysis of resource occupancy,a large part of the uplink PRB resources of TD-LTE network is used for pre-scheduling overhead.According to the research on pre-scheduling mechanism and algorithm,a pre-scheduling scheme for sub-QCI bearers is proposed.The TD-LTE uplink resource constrained optimization method combines the network perception to analyze the optimization result,and obtains the applicable scope of the solution to reduce the network load under the premise of ensuring user perception.
