Description

一种数据传输方法及其装置 技术领域
本发明涉及通信技术领域,尤其涉及一种数据传输的技术领域。
背景技术
在下行数据调度过程中,基站通过下行控制信令(downlink control information,DCI)为特定用户设备(user equipment,UE)调度时频资源并指示相应传输方式。该UE利用所提供的时频资源和传输方式做数据接收,并在给定的资源位置上反馈数据接收情况。网络可以为没能成功接收数据的用户再次调度重传数据。
一个神经网络的使用过程包括:训练阶段和推理阶段。在训练阶段,首先将包括大量数据的训练集合作为待训练模型的输入参数输入神经网络。神经网络基于特定的训练算法,通过大量的训练和参数迭代,确定待训练模型的待确定参数,从而得到一个训练好的神经网络模型。例如可通过大量小狗的图片训练一个识别小狗的神经网络。在推理阶段,可以使用训练好的神经网络进行识别、分类或信息恢复等推理操作。例如可通过训练好的神经网络识别出图像中的小狗。
传统的神经网络的训练是集中式的,例如在数据中心收到大量训练集数据后进行模型训练。考虑到用户隐私保护、算力分布等因素,提出一种新的神经网络训练方式:“联邦学习”。在“联邦学习”的训练过程中,训练集分布在各个子节点(用户设备)上。“联邦学习”的训练过程包括:(1)各个子节点基于本地训练集生成本地局部神经网络,并将该本地局部神经网络上传至主节点(网络);(2)主节点根据获得的各个本地局部神经网络合成当前全局神经网络,并将全局神经网络传输至各个子节点;(3)子节点使用新的全局神经网络做下一次训练迭代。最终在多个子节点和主节点的协作下完成神经网络的训练。
在做联邦学习的神经网络训练时,大量的下行周期性数据需要传输至多个子节点。如果现有技术中的下行数据调度方式,下行数据传输效率很低。例如,当网络需要将100份数据分别在100个时间点上周期性传输至1000个用户时,如果采用现有技术中的下行数据调度方式则需要做100*1000次的DCI调度,并传输100*1000次的数据内容。
