Abstract

Description

一种信令传输方法及装置、网络设备 技术领域
本申请涉及无线通信技术领域,尤其涉及一种信令传输方法及装置、网络设备。
背景技术
在新无线(NR,New Radio)系统中,第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)的一个研究课题是无线中继,具体地,中继节点(RN,Relay Node)通过无线方式连接到其归属的锚点基站,该锚点基站也称为Donor,终端可以与Donor直接连接,也可以通过一个或多个中继节点间接地与Donor连接。NR对于无线中继具有如下要求:1)要求支持固定节点到中继节点的多跳传输,2)要求支持固定节点到中继节点的冗余路径传输,3)要求支持中继节点到固定节点的骨干路径的自动配置。
相比于传统的用户设备(UE,User Equipment)到基站的单跳接口,无线中继架构的不同点在于,当一个分组数据汇聚协议(PDCP,Packet Data Convergence Protocol)协议数据单元(PDU,Protocol Data Unit)数据包从发送端(例如Donor/UE)发出时,即使该数据包正确发送给了下一跳网络节点,实际上可能仍然无法被接收端(例如UE/Donor)正确接收。传统的UE到基站的单跳接口,PDCP层通过无线链路控制(RLC,Radio Link Control)层上的包正确接收状态信息(ARQ status report)来获知RLC传输状态,从而触发相应的数据恢复(data recovery)过和重建(reestablishment)过程。如上所述,在中继网络架构中,如果该RLC传输状态无法被PDCP层正确获知,则会影响data recovery过程和reestablishment过程的实现。
此外,对于PDCP丢弃(PDCP discard),当前传统的UE到基站的单跳接口,PDCP层可以直接指示RLC层进行数据包丢弃,但是在无线中继架构下,PDCP层和RLC层位于不同的网络节点,并且之间相隔一个适配层(Adapt),如何实现层间交互需要解决。
