其中，终端设备直接与网络侧设备连接称为直接链路(Direct Link)，终端设备通过中继终端设备与网络侧设备连接称为间接链路(Indirect Link)。
本公开实施例中，针对相关技术中，终端设备的承载的数据的传输路径为直接链路或间接链路，传输路径为直接链路和间接链路中的一种，终端设备不支持在多条传输路径上进行承载的数据进行传输的 问题，提出一种数据传输配置方法，网络侧设备向终端设备发送第一传输配置，第一传输配置用于指示承载的数据的传输路径，传输路径包括至少两个，由此，终端设备的承载的数据支持在至少两个传输路径上进行传输，能够提高数据传输的可靠性。
其中，至少两个传输路径可以包括终端设备直接与网络侧设备连接的直连链路，以及终端设备通过中继终端设备与网络侧设备连接的间接链路。由此，终端设备的承载的数据可以同时通过直接链路和间接链路进行传输，能够提高数据传输的可靠性。
为了提高数据传输的可靠性，网络侧设备可以为终端设备的无线承载配置多个发送路径，对于来自某个PDCP(package data convergence protocol，包数据汇聚协议)实体的数据，配置多个RLC(radiolink control，无线链路控制)实体，发送路径可以通过小区组(MCG(master cell group，主小区组)或者SCG(secondary cell group，辅小区组))和逻辑信道标识确定。
