值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、 智能脚镯、智能脚链等)、智能腕带、智能服装、游戏机等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面将对本申请实施例中出现的名词作出如下解释：
1.小数据传输
小数据传输是针于非连接态的终端的一种数据传输方式，其可以通过极简单的信令交互过程即完成小数据传输，其目的在于避免引起的RRC状态转换和RRC连接建立过程中所造成过多信令开销。
小数据传输方案的特点是：终端当前的数据无线承载(data radio beare，DRB)都是处于挂起的状态，而不是释放的状态。因而，UE在发送恢复请求消息ResumeRequest前可以先恢复DRB，然后再用RRC信令来捎带小数据，这时和连接态CONNECTED终端一样，可以在DRB上传输数据，如此，可以避免进行状态转换，从而以较小的信令开销达到高效小数据传输的目的。
小数据传输的待传数据在专用业务信道(Dedicated Traffic Channel，DTCH)上承载，与上行RRC连接恢复请求消息(RRC Connection Resume Request)进行复用之后进行传输。类似的，如果有回复的下行消息，也可以在DTCH上承载，与下行RRC Connection Release消息复用传输。
2.重复传输
在Rel-15、Rel-16NR系统中，UE进行物理上行共享信道(Physical Uplink Shared Channel，PUSCH)或者物理下行共享信道(Physical Downlink Shared Channel，PDSCH)重复传输能力都是强制的，换而言之，UE一定能支持PUSCH/PDSCH重复传输。
在实际应用中，网络侧设备可以通过RRC信令配置(例如，pusch-AggregationFactor，pdsch-AggregationFactor)来指示终端动态调度的PUSCH或者PDSCH的重复传输次数，终端会根据该指示在连续若干个时隙上进行PUSCH或者PDSCH重复传输。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的小数据传输的数据传输方法进行详细地说明。

在本申请实施例中，上述终端确定目标重复传输次数的方式可以用户自定义的，也可以终端预设的。

在本申请实施例中，在终端设备确定目标信息进而确定目标重复次数后，将可以根据第一配置信息确定的传输环境，通过目标重复传输次数进行数据的重复传输。
可以理解的是，上述重复传输过程中，是对小数据的重复传输，也即，不同于以往的进行小数据单次传输，在确定目标重复传输次数后，可以按照目标重复传输次数进行数据的多次传输。
在本申请实施例中，终端先行获取包括用于SDT的传输资源和传输配置参数中的至少一者第一配置信息，之后，在终端触发SDT过程后，将确定目标重复传输次数，最后，终端将根据上述第一配置信息和目标重复传输次数，进行重复传输。如此，在触发小数据传 输过程后，终端可以根据确定的重复传输次数进行重复传输，从而避免在信号较差的区域由于单次传输次数所导致的传输过程信令交互过程缺乏，进而导致传输数据失败的问题，提升数据传输的可靠性。
