Abstract

本发明提供了数据传输方法、基站及用户设备，用于防止LTE‑WLAN汇聚过程中的数据丢失。本发明实施例方法包括：基站获取UE的第一数据丢失指示参数和第二数据丢失指示参数，第一数据丢失指示参数用于指示UE确认丢失的PDCP PDU，第二数据丢失指示参数用于指示第一最高序列号，第一最高序列号为UE接收的PDCP PDU的最高序列号，基站再根据第一数据丢失指示参数和第一最高序列号确定UE未接收到的PDCP PDU，再将未接收到的PDCP PDU发送给UE。通过本发明实施例，基站根据UE发送的第一数据丢失指示参数和第二数据丢失指示参数可以确认UE丢失的全部的PDCP PDU，并将其重发给UE，从而可以防止LTE‑WLAN汇聚过程中的数据丢失。
