Abstract

本公开是关于一种数据传输方法和装置，上述方法包括：接收基站发送的配置信息，配置信息用于指示预设数据承载的PDCP层是否开启数据包删除功能；若预设数据承载的PDCP层开启了数据包删除功能，在预设数据承载的PDCP层向RLC层传输服务数据单元时，记录传输服务数据单元的时长；确定在传输服务数据单元的时长大于预设时长时的情况下，服务数据单元中尚未传输至RLC层的第一服务数据单元；删除第一服务数据单元。根据本公开的实施例，在删除PDCP层的服务数据单元的基础上，可以保留PDCP层的协议数据单元，使PDCP层的协议数据单元得以传输至RLC层并传输至接收端，从而在一定程度上实现主动队列管理的基础上，避免序列号出现缺失，保证接收端能够顺利地接收数据。
