现有LTE(Long Term Evolution,长期演进)系统中,UE的随机接入过程采用四步机制,如图1所示,四步机制分为msg1随机接入前导(Random Access Preamble)、msg2随机接入响应(Random Access Preamble)、msg3调度传输(Scheduled Transmission)、msg4冲突检测(Contention Resolution)。对于5G NR(next generation Radio,下一代无线)中的上行多波束(multi-beam)PRACH(Packet Random Access Channel,分组随机接入信道)传输存在控制面时延较大的问题,无法满足针对URLLC(Ultra Reliable&Low Latency Communication,超高可靠性与超低时延)场景定义的低时延的性能指标。
目前,为了减小时延,标准中讨论在传输msg1时,将前导码和数据同时 发出,如图2所示,采用两步机制进行随机接入,该过程包括:msg1随机接入前导(Random Access Preamble)+数据(Data)、随机接入响应(Random Access Preamble),相对于LTE的四步随机接入机制,省略了Msg3和Msg4,可有效降低控制面时延。
然而,UE和基站如何确定Msg1中数据部分的编码调制方式,目前没有解决方案。

实施例1:
图3为本发明实施例1提供的一种数据传输过程示意图,该过程包括:
步骤301:针对初始接入的上行数据传输,根据协议规定和/或基站广播的信息,确定上行数据的编码调制方式。
在本发明实施例中编码调制方式可以是协议规定的,也可以是基站广播的,当然也可以同时由协议规定和基站广播确定。
协议规定可以规定一种编码调制方式,也可以规定多种编码调制方式,针对初始接入的上行数据,如果协议只规定了一种编码调制方式,UE将该编码调制方式确定为上行数据的编码调制方式;如果协议规定了多种编码调制方式,UE可以在规定的多种编码调制方式中随机选择一种编码调制方式,将该编码调制方式确定为上行数据的编码调制方式。
基站广播可以广播一种编码调制方式,也可以广播多种编码调制方式,针对初始接入的上行数据,如果基站只广播了一种编码调制方式,UE将该编码调制方式确定为上行数据的编码调制方式;如果基站广播了多种编码调制方式,UE可以在广播的多种编码调制方式中随机选择一种编码调制方式,将该编码调制方式确定为上行数据的编码调制方式。
如果同时由协议规定和基站广播编码调制方式,则可以从协议规定和基站广播的编码调制方式的交集中选择一种编码调制方式,将其确定为上行数据的编码调制方式。
步骤302:采用确定的编码调制方式对上行数据进行编码调制,发送前导码和编码调制后的上行数据。

具体的,针对初始接入的上行数据传输,即消息1,根据协议规定和/或基站广播的信息中包含的上行数据的编码调制方式,确定上行数据的编码调制方式;采用确定的编码调制方式对上行数据进行编码调制,发送前导码和编码调制后的上行数据。例如:协议规定或基站广播的信息中指示了针对初始接入的上行数据传输时采用的一种编码调制方式,采用该编码调制方式对上行数据进行编码调制,发送前导码和编码调制后的上行数据。或者,协议规定和基站广播的信息中指示了针对初始接入的上行数据传输采用的编码调制方式,UE采用该编码调制方式对上行数据进行编码调制,发送前导码和编码调制后的上行数据。
由于在本发明实施例中,针对初始接入的上行数据传输,根据协议规定和/或基站广播的信息,确定上行数据的编码调制方式,从而可以对上行数据进行编码调制。

协议规定和/或基站广播可以规定至少两种编码调制方式,则UE在确定上行数据的编码调制方式时,UE可以在该至少两种编码调制方式中随机选择一种编码调制方式作为上行数据的编码调制方式。
