具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
诸如AR(Augmented Reality，增强现实)、VR(Virtual Reality，虚拟现实)、车车通信等新型互联网应用的不断涌现，对无线通信技术提出了更高的要求，驱使无线通信技术不断进行演进以满足应用的需求。目前，蜂窝移动通信技术正在处于新一代技术的演进阶段，其中一个重要特点就是支持多种业务类型的灵活配置。
不同的业务类型对于无线通信技术有不同的要求，例如，eMBB(enhanced Mobile Broad Band，增强移动宽带)主要侧重于较大带宽、较高速率等方面；URLLC(Ultra Reliable Low Latency Communication，超高可靠超低时延通信)主要侧重于较高可靠性、较低时延方面；mMTC(massive Machine Type Communication，大型机器类通信)主要侧重于较大连接数方面。
随着业务需求的驱动，仅仅使用授权频谱无法满足蜂窝移动通信系统业务的需求。鉴于此，3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)中提出LAA(License Assisted Access，辅助许可接入)机制，通过授权频谱来辅助实现在非授权频谱上的使用，将蜂窝移动通信系统部署到非授权频谱。非授权频段的使用需要满足预设的规则，并且非授权频段上可能存在其它的移动通信系统如Wi-Fi(Wireless-Fidelity，无线保真)系统、Zigbee(紫蜂协议)等，不同移动通信系统之间的共存问题也是需要考虑的。
在非授权频谱的通信过程中，存在隐藏设备问题(hidden station)：当互不可见(无线信号互不能达)的设备A和设备B同时通过非授权频谱中与双方信号都可达的设备C传输数据时，由于设备A和设备B都无法在非授权频谱中检测到对方的信号，于是都认为此时非授权频谱为空闲状态，同时与设备C交换数据，从而造成信号干扰。
针对上述问题，电气和电子工程师协会(Institute of Electrical and Electronics Engineers，IEEE)的IEEE 802.11标准中提出了RTS(Request To Send，请求发送)/CTS(Clear To Send，清除发送)协议的运行机制，具体如下：
图1，示出了IEEE 802.11标准中的RTS/CTS协议的运行机制。
发送设备110和接收设备120通过交换发送RTS信号和CTS信号实现握手，并通过RTS信号和CTS信号中携带的时间字段，在完成数据传输和相应的反馈之前，清空发送设备和接收设备周围的信道。
发送设备110在载波监听到信道空闲，并退避DIFS(Distributed Inter Frame Space，分布式帧间间隔)时间后，广播RTS信号。
监听到RTS信号的其它设备130按照RTS信号中携带的NAV(Network Allocation Vector，网络分配矢量)时间进行退避，RTS信号中携带的NAV时间包含发送设备110后续发送数据以及接收到ACK(Acknowledgement，确认)所需的整体时间。
接收设备120接收到RTS信号后，在SIFS(Short Interframe Space，短帧间间隔)时间后广播CTS信号。
监听到CTS信号的其它设备130根据CTS信号中携带的NAV时间进行退避，CTS信号中携带的NAV时间包含从CTS信号结束到数据传输完成并进行一次相应的ACK所需的时间。
在LAA机制中存在LBT(Listen Before Talk，载波监听)机制：发送设备110在发送数据前，需要不断地检测非授权频谱中的占用状态，若非授权频谱处于被占用状态，发送设备只有在确定非授权频谱再次处于空闲状态后，才能占用非授权频谱发送数据。由于发送设备在确定信道处于空闲状态前需要不断的检测信道是否空闲，从而造成较多的能量消耗。
图2，示出了本公开一个示例性实施例提供的通信系统的架构示意图。如图2所示，该通信系统200包括第一设备210、第二设备220以及第一目标设备230。
第一设备210可以是UE(User Equipment，用户设备)，也可以是接入网设备。当第一设备210是接入网设备时，该接入网设备可以是基站，本发明实 施例对接入网设备的具体实现方式不加以限定。
第二设备220可以是UE，也可以是接入网设备。当第二设备220是接入网设备时，该接入网设备可以是基站，本公开实施例对接入网设备的具体实现方式不加以限定。
第一设备210可通过非授权频谱向第一目标设备230发送数据，在第一设备210向第一目标设备230发送数据前，需要确定非授权频谱的占用状态。可选的，第一目标设备230为UE。
当第一设备210或第二设备220为基站时，该基站通常设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈、物理层(Physical，PHY)协议栈。
图3，示出了本公开一个示例性实施例提供的非授权频谱中的通信方法。该方法可应用于图2实施例中的通信系统200中，该方法包括：

可选的，第一指示信号中包含的信息包括第一指示信息、第二指示信息、第三指示信息以及第四指示信息中的至少一种。
第一指示信息用于指示占用非授权频谱传输数据的通信系统的信息，该通信系统包括蜂窝移动通信系统(以下简称为蜂窝系统)、Wi-Fi系统或Zigbee系统。例如，该机制支持的通信系统的集合为{蜂窝系统，Wi-Fi系统，Zigbee系统}。当第一设备是UE时，该通信系统的集合可预先存储于第一设备中，或由与第一设备建立连接的接入网设备发送给第一设备。
