Abstract

本申请公开了一种数据传输方法、装置、通信设备及存储介质，属于无线通信技术领域。方法包括：通过组播或广播方式向至少两个站点发送数据块；接收至少两个站点发送的块确认BA信息，BA信息用于指示对应的站点接收失败的数据单元；根据至少两个站点发送的BA信息，对至少两个站点接收失败的数据单元进行异或编码，获得数据块的网络编码数据；通过组播或广播方式向至少两个站点发送网络编码数据。上述方案通过获取各个站点对数据单元的接收情况，对需要重传的数据单元进行异或编码，从而在保证各个站点能够根据编码后的数据解码得到未接收成功的数据单元的同时，减少需要传输的数据量，从而提高组播或广播场景下的重传效率。
