5G IAB基站接入网络方案研究

Discussion on 5G IAB Basestation Access Network Solution

在5G新空口(New Radio,NR)研究中提出了集成无线接入链路和无线回传链路(Integrated Access and Backhaul,IAB)的基站。IAB基站启动后其移动终端(Mobile-Termination,MT)功能将通过小区选择接入网络,因此需要保证IAB基站能够接入IAB网络,从而实现IAB基站的功能。提出的5G基站(gNB)协助IAB基站接入IAB网络的方案,解决了IAB基站启动后能够最终接入IAB网络的问题。

In the exploration of 5G new radio interface,a basestationofintegrated IAB(Integrated Access and Backhaul)is proposed.After the IBA basestation is started,its MT(mobile terminal)functionwould access the network through the cell selection.Therefore,it is necessary to ensure that the IAB basestation can access the IAB network and realize the function of the IBA basestation.The proposed 5G basestation(gNB)assists the IAB basestation to access the IAB network,and solves the problem that the IAB basestation can access the IAB network after startup.
