Abstract
本申请公开了一种通信方法及通信装置，其中通信方法包括：IAB节点接收来自源宿主基站的第一配置信息，该第一配置信息包括N个目标宿主基站为该IAB节点配置的N个MT的配置信息和N个DU的配置信息，当该IAB节点的MT满足特定条件时，该IAB节点的DU应用所述N个DU的配置信息中的一个配置信息，其中，N大于或等于1，MT用于与该IAB节点的上级节点或者所述源宿主基站或者所述目标宿主基站通信，DU用于与该IAB节点的下级节点或者终端通信。该方法在实现IAB节点的跨宿主基站的切换的过程中，可避免IAB节点的DU发送例如SSB的资源与IAB节点的MT发送SSB的资源发生冲突，进而尽量避免终端的通信异常。
