具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在一个示例性实施方式中，图1为本申请提供的一种数据发送方法的流程示意图。该方法可以适用于第一节点在非激活(Inactive)状态或无线资源控制状态为空闲状态的情况下向第二节点发送数据的情况。该方法可以由本申请提供的数据发送装置执行，该数据发送装置可以由软件和/或硬件实现，并集成在第一节点，如终端上。
针对物联网，3GPP(The third Generation Partnership Project，第三代合作伙 伴计划)标准组织制定了MTC(Machine Type Communication，机器类型通信)和NB-IoT(Narrow Band Internet of Things，窄带物联网)两个非常具有代表性的通信标准协议。针对移动互联网，3GPP标准组织最新制定了5G(5 Generation，第五代)NR(New Radio，新无线)通信标准协议。针对物联网和物联网的通信标准协议，终端从RRC空闲状态进入RRC连接状态会消耗终端的功耗以及系统资源。本申请提供的数据发送方法可以认为是信道的发送方法，能够有效节省第一节点的功耗。
如图1所示，本申请提供的一种数据发送方法，包括S110和S120。
S110、在非激活状态或无线资源控制状态为空闲状态的情况下，通过第一上行信道发送数据到第二节点。
第一节点在非激活状态或RRC状态为空闲状态的情况下，通过第一上行信道发送数据到第二节点。第一上行信道资源的配置包括以下至少之一：由基站配置；周期配置；配置为第一节点专用的。即第一上行信道资源可以由第二节点配置，也可以是周期配置的，还可以是第一节点专用的上行信道资源。
本申请中在向第二节点发送数据的情况下，无需从RRC空闲状态进入RRC链接状态，直接在RRC空闲状态或非激活状态利用第一上行信道发送数据即可。
S120、检测第一搜索空间中的下行控制信道。
第一搜索空间即需要检测的一组下行控制信道的集合，第一搜索空间中包括至少一个下行控制信道的发送位置信息。第一上行信道和第一搜索空间可以存在对应关系，在第一上行信道发送数据后，可以检测对应第一上行信道的第一搜索空间中的下行控制信道。检测的目的不作限定，如可以包括确定第一上行信道的数据是否被第二节点接收成功，或接收第二节点基于第一上行信道发送的数据的反馈数据。
可以理解的是，第一搜索空间中可以包括需要检测的一组下行控制信道，各下行控制信道中承载下行控制信息(Downlink Control Information，DCI)。
本申请提供的一种数据发送方法，在非激活状态或无线资源控制状态为空闲状态的情况下，通过第一上行信道发送数据到第二节点；检测第一搜索空间中的下行控制信道。有效地解决了第一节点从RRC空闲状态进入RRC连接状态会消耗第一节点的功耗以及系统资源的技术问题，本申请中第一节点无需进 行RRC状态的切换，节省了第一节点的功耗。
