具体实施方式
为了能够更加详尽地了解本发明实施例的特点和技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
在对本发明实施例进行详细描述之前，首先对相关技术中在免授权频谱上数据传输的实现过程以及确定Slot-Format的方式进行简要说明。
免授权频谱是国家和地区划分的可用于无线电设备通信的频谱，免授权频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。为了让使用免授权频谱进行无线通信的各个通信系统在免授权频谱上能够友好共存，一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如，在欧洲地区，通信设备遵循“先听后说” (listen-before-talk，LBT)原则，即通信设备在免授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，通信设备才能进行信号发送；如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙，通信设备不能进行信号发送。且为了保证公平性，在一次传输中，通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupation Time，MCOT)。在NR非监听(unlicensed)技术中，在免授权频谱上使用NR技术实现数据传输。
在使用免授权频谱的系统中，网络设备发送下行信道和信号的传输有可能是不连续的，而终端设备并不知道网络设备何时开始占用下行信道进行传输；因此，终端设备需要不断的检测下行信道，增加了终端设备的功耗。为了减少终端设备的功耗，在网络设备进行信道侦听的结果为空闲后，发送指示信号给终端设备，通知终端设备网络设备已经获得下行传输机会。终端设备收到指示信号后，开始接收相应的下行信道和信号，例如物理下行控制信道(Physical Down Control Channel，PDCCH)，参考信号等。终端设备在接收到指示信号之前，可以不检测除指示信号之外的下行信道和信号，或者以较长的周期检测包括指示信号在内的下行信道和信号。
相关技术中，确定Slot-Format的方式包括：网络设备通过tdd-UL-DL-Configuration进行半静态配置，以及网络设备通过组公共物理下行控制信道(Group Common PDCCH)动态的通知终端设备时隙格式指示(Slot Format Indicator，SFI)。
网络设备通过时分双工-下行链路-上行链路-链路配置(tdd-UL-DL-Configuration)进行半静态配置时，存在Slot-Format配置不灵活的问题。
由于在NR系统中，网络设备发送下行信道时需要进行LBT，并且一次下行传输占用信道的时间有限；因此，下行信道和信号的传输可能是不 连续的。网络设备进行LBT获得下行传输机会后，通过Group Common PDCCH动态的通知终端设备SFI时，由于Group Common PDCCH的搜索空间是由网络设备配置的、且是周期性的；因此，当网络设备获得下行传输机会、且当前不是发送Group Common PDCCH的时刻时，网络设备不能够在有限的传输时间内，及时地通过Group Common PDCCH通知终端设备SFI；由于终端设备不能够及时地确定Slot-Format，网络设备和终端设备之间就不能无法进行数据传输，降低了数据传输效率。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。
