进一步说明，所述通信节点和其他通信节点之间可以实现通信，所述通信节点可能未分配有终端标识信息(即终端未进入过该通信节点，未与该通信节点进行数据传输)，从而通信节点可以从锚点基站获得所述终端的加密信息和完整性保护信息，根据所述完整性保护信息对所述第一数据块进行完整性校验，在校验成功的情况下，根据所述加密信息解密所述第一数据块；或者，还可以将其发送给锚点基站，由其处理后发送给通信节点。

图3为本申请实施例提供的再一种数据传输方法的流程示意图；如图3所示，本实施例提供一种数据传输方法的具体实施例，针对上述图1和图2所示的方法具体说明。
步骤301、确定用于数据早传的共享资源。
具体来说，所述步骤301，包括：
通信节点(假设为基站1、gNB1)和其他通信节点(假设为基站2、gNB2)协商确定用于数据早传的共享资源的信息；所述共享资源包括以下至少一种资源：preamble、PRACH、PUCCH和PUSCH。
进一步的，所述确定用于数据早传的共享资源，还包括：

配置与所述共享资源相关联的逻辑信道，以进行数据传输。
步骤302、向终端(UE)发送用于数据早传的共享资源。
通信节点(gNB1和/或gNB2)向UE发送用于数据早传的共享资源后， UE接收用于数据早传的共享资源，即可基于所述共享资源进行数据传输。
进一步的，通信节点(gNB1和/或gNB2)向UE发送共享资源的信息时，还会携带指示共享区域的信息。所述指示共享区域的信息，包括至少以下一种信息：
测量的基站1、gNB1下的小区的RSRP、RSRQ和/或RSSI的范围；
测量的基站2、gNB2下的小区的RSRP、RSRQ和/或RSSI的范围；
终端上下文保留的TA(参考，该项只对离开连接态后不移动的UE有效)；
小区的位置。
步骤303、UE使用共享资源向通信节点发送第一消息。
具体来说，在应用过程中，对于配置或激活复用(duplication)的上行数据，当UE确定上行数据满足早传条件时，UE可以使用所述共享资源发送所述上行数据。这里，所述早传条件，可以包括：上行数据的数据量小于预设阈值，和/或，上行数据的数据时延要求较低，具体可以是延时要求大于预设阈值。
所述UE使用上述共享资源向通信节点发送上行数据，包括：
所述UE使用上述共享资源向gNB1或gNB2发送第一消息，所述第一消息，包括：RA preamble和第一数据块(即所述上行数据)；或者，所述第一消息，包括：PRACH和第一数据块(即所述上行数据)；
所述第一数据块携带有终端标识信息(UE ID)。这里，所述终端标识信息，可以采用类似现有的随机接入信道(RACH，Random Access Channel)中的消息1和消息3中UE ID。
这里，所述UE发送第一消息时，可以将包括RA preamble和第一数据块的第一消息分两步发送；第一步，UE发送RA preamble和部分数据块的消息(所述部分数据块的消息可以包括第一数据块的长度信息)；第二步， UE发送剩下的第一数据块。
需要说明的是，是否采用上述分两步发送的方法，取决于第一数据块的大小、以及小区的覆盖和UE在小区的位置(UE在小区边缘，就比UE在小区中心发的数据块小)，比如，第一数据块较大或者UE处于小区的边缘时，可能导致数据传输出现问题，此时就不能一次发完。第一条消息是开环功控，不能发太大。
步骤304、告知其他通信节点收到第一消息。
具体来说，当gNB1接收到UE发送的第一消息后，告知gNB2接收到第一消息；反之，当gNB2接收到UE发送的第一消息后，告知gNB1接收到第一消息。
步骤305、通信节点确定第二消息，向UE回复第二消息。
具体来说，所述步骤305包括：
通信节点(gNB1和/或gNB2)收到第一消息后，协商确定一个gNB向发送第二消息；
根据第一消息确定需回复的第二消息，确定第二消息包括下行数据并有高可靠性要求，则gNB1和gNB2可以都给UE发送第二消息。
所述第二消息，包括：随机接入响应(RAR，Random Access Response)、冲突解决消息(Contention resolution)。
这里，所述第二消息携带有共享区域的信息，如基站、小区的信息。
所述根据第一消息确定需回复的第二消息之前，所述方法还包括：解析所述第一消息；具体来说，所述第一消息携带有UE ID，如果gNB2接收到第一消息，并确定其未分配或未保存有该UE ID，gNB2需要根据UE ID中携带的基站和小区的信息，找到锚点基站(可以是上述gNB1，也可以是其他基站)，获取UE的上下文(包括加密信息、完整性保护信息)，解开第一数据块；或者直接把接收到的UE ID和第一数据块，转发给锚点基站， 由其解开后发送给gNB2。
本实施例中，考虑到上行(UL，Upline)同步的限制(如果UE到两个基站的时延TA差别太大，两个基站无法同时收到UE的上行数据)；基站之间交互共享资源，并进一步协商哪些共享资源可以用于通信节点之间共享和复用，进行数据早传的同时接收；以及可以共享资源的范围。
本实施例中，所述通信节点可以采用上述基站、即gNB1和gNB2(具体对应附图3中实线部分对应的流程，具体包括：步骤301、步骤302、步骤303、步骤304、步骤305)；通信节点也可以是DU、即DU1和DU2。
具体来说，通信节点为DU时，可以通过CU进行协商，即由CU来确定不同DU下哪些共享资源可以用于基站间共享和复用，进行数据早传的同时接收，且多个DU将数据转给CU进行合并处理，具体对应附图3中虚线部分对应的流程；所述方法具体包括：
步骤311、CU确定共享资源，并发送给DU1和DU2。
在另一实施例中，CU确定共享资源后，也可以是发送给DU2，由DU2将共享资源发送给DU1，这里不做限定。
步骤312、与步骤302相同，向UE发送用于数据早传的共享资源。
步骤313、与步骤303相同，UE使用共享资源向通信节点发送第一消息。
步骤314、与步骤304相同，告知其他通信节点收到第一消息。
具体来说，当DU1接收到UE发送的第一消息后，告知DU2接收到第一消息；反之，当DU2接收到UE发送的第一消息后，告知DU1接收到第一消息。
步骤315、将接收到的第一消息发送给CU或相邻基站(Neigbour-gNB)。
步骤316、集中处理单元(CU)或相邻基站(Neigbour-gNB)确定第二消息，并通过DU1或DU2向UE发送第二消息。
所述第二消息，包括：随机接入响应(RAR，Random Access Response)、冲突解决消息(Contention resolution)。
实施例二，采用与上述实施例一(即图3所示方法)相似的方案，区别在于，本实施例中，可以由gNB1和gNB2在收到共享资源后，便为了这个UE自构成类似双连通性(DC，Dual Channel)的结构，即，某个gNB1具有汇聚层，如分组数据汇聚协议(PDCP，Packet Data Convergence Protocol)和/或无线链路控制协议(RLC，Radio Link Control)只在某个通信节点生效。
实施例三、采用与上述实施例一相似的方案，区别在于，本实施例中，可以采用半静态预留资源作为所述共享资源，即通信节点之间交互共享的半静态预留资源(可以是公共的半静态预留资源或分组的半静态预留资源)；通信节点之间进一步协商出一个共享的加密信息和/或完整性保护信息(如，MAC-I信息)；通信节点将共享的半静态预留资源发送给UE。具体可以是小区在发送系统消息时一同广播出所述半静态预留资源的信息；或者，小区通过预设格式的消息发送所述半静态预留资源的信息(如在离开RRC连接态时的RRC释放消息)。
