NR系统提出了灵活的时隙格式，其中，时隙格式可以表示为一个时隙中包括的下行(Downlink)符号，灵活(Flexible)符号，上行(Uplink)符号的信息。这样的时隙构成可以称为不同的时隙格式(slot format，SF)。

Figure PCTCN2020074756-appb-000002
NR系统中，时隙格式指示(Slot format indicator，SFI)信息可以通过公共物理下行控制信道(Group-common Physical Downlink Control Channel，GC-PDCCH)传输，对应的下行控制信息(Downlink Control Information，DCI)格式是DCI格式2-0。DCI格式2-0对应的循环冗余校验(Cyclic Redundancy Check，CRC)可以通过SFI-无线网络临时标识(Radio Network Temporary Identity，RNTI)加扰，其中，SFI-RNTI可以是高层配置的。
DCI格式2-0的大小可以是高层配置的，DCI格式2-0的最大比特数为128比特。一个DCI格式2-0中可以包括一个或一组小区的SFI信息。具体地，DCI格式2-1传输的DCI信息可以如下所示：
SFI 1，SFI 2，…，SFI N
其中，SFI 1表示小区1的SFI信息，SFI 2表示小区2的SFI信息，…，SFI N表示小区N的SFI信息。一个SFI索引(SFI-index)域(例如SFI 1)的大小可以为9比特，用于指示一个时隙格式组合标识。
对于每个小区，终端设备可以被配置以下信息：小区标识、DCI格式2-0中SFI-index域的位置、时隙格式组合集合、参考子载波间隔。其中，时隙格式组合集合中的每个时隙格式组合可以包括：时隙格式组合标识和至少一个时隙格式指示，该时隙格式组合标识和该至少一个时隙格式指示对应。对于参考子载波间隔，如果是非配对频谱工作方式，参考子载波间隔可以为正常上行载波或增补的(supplementary)上行载波对应的参考子载波间隔；如果是配对频谱工作方式，参考子载波间隔可以为下行(Downlink，DL)带宽部分(BandWidth Part，BWP)或上行(Uplink，UL)BWP对应的参考子载波间隔。
在终端设备确定小区1的时隙格式的过程中，具体地，终端设备根据SFI-RNTI检测到DCI格式2-0后，可以根据高层配置的参数找到小区1的标识，并且终端设备可以确定小区1的SFI-index域在检测到的DCI格式2-0中的起始位置，然后终端设备可以从该起始位置开始读取一个SFI-index域，并根据该SFI-index域指示的时隙格式组合标识从高层配置的时 隙格式组合集合中确定小区1的时隙格式。
通常情况下，终端设备通过上述方式确定的时隙格式的时间长度大于或等于用于承载DCI格式2-0的PDCCH的检测周期。也就是说，终端设备可能在两个不同的时间接收到两个SFI指示信息，该两个SFI指示信息指示的时间长度可能有部分重叠，其中，在重叠的时间长度上该两个SFI指示信息指示的时隙格式相同。
为了加深对本申请实施例的理解，下面对免授权频谱做简单介绍。
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，该频谱可以被认为是共享频谱，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，可以不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该频谱上能够友好共存，需要基于先听后说(Listen Before Talk，LBT)的原则，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(或称为信道检测)，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上进行信道侦听的结果为信道忙，则不能进行信号发送。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可以不超过最大信道占用时间(Maximum Channel Occupation Time，MCOT)。
在授权辅助接入(Licensed-Assisted Access，LAA)-LTE系统中的下行信号传输过程中，如图2所示，如果网络设备的LBT失败，则不能进行信号传输。如果网络设备的LBT成功，网络设备可以进行一次传输机会不超过MCOT的下行传输。其中，一次下行传输机会可以定义为网络设备连续传输的时间单元。
由于网络设备的传输是机会性的，只有LBT成功才能传输，LBT失败时不能传输，因此，在该网络设备服务的小区中的终端设备为了实现和网络设备进行正确的数据通信，需要确定网络设备什么时候开始进行下行传输，什么时候停止下行传输。为了解决该问题，在LAA-LTE系统中，网络设备发送的每个子帧上可以存在小区专属导频信号(Cell-specific Reference Signals，CRS)，从而终端设备可以通过检测当前子帧上是否存在CRS来判断该子帧上是否有网络设备的下行传输。对于下行传输的结束位置，参考图2，网络设备可以通过在下行传输的最后一个子帧和倒数第二个子帧上传输下行控制信息DCI来指示，该DCI中包括该下行传输结束位置对应的符号的指示信息。另外，在LAA-LTE系统中，当网络设备发起一个COT时，该COT中只允许有一个上下行转换点，因此该COT内的下行传输以及可能存在的上行传输都是连续的，终端设备只需要确定下行结束位置和上行的COT，就可能确定COT内的时隙结构。由于LAA-LTE不支持独立布网，在LAA-LTE载波上也可以没有用于系统信息传输的资源。
然而，对于NR-U系统，由于继承了NR的灵活时隙配置，且支持COT内包括多个上下行转换点，因此也支持更灵活的时隙格式。并且，NR-U系统支持独立布网，因此需要考虑在NR-U载波上传输初始接入相关的系统信息。在该场景下，基于类似于NR系统中的DCI格式2-0，如何确定NR-U系统中的时隙格式，目前还没有明确的规定。为了解决上述问题，本申请实施例提出了一种确定时隙格式的方法，可以有效实现NR-U系统中的时隙格式确定。
图3是根据本申请实施例的确定时隙格式的方法200的示意性流程图。图3所述的方法可以由终端设备和网络设备执行，该终端设备例如可以为图1中所示的终端设备120，该网络设备例如可以为图1中所示的网络设备110。如图3所示，该方法200可以包括以下内容中的至少部分内容。
在210中，终端设备确定第一载波上的目标时间窗，所述目标时间窗包括发现参考信号DRS传输窗口和信道占用时间(Channel Occupancy Time，COT)窗口中的至少一个，所述DRS传输窗口用于传输同步信号块(Synchronization Signal/PBCH Block，SSB)。
在220中，终端设备根据所述目标时间窗确定所述第一载波上的时隙格式。
可选地，终端设备接收网络设备发送的第一指示信息。所述终端设备根据接收的第一指示信息确定所述DRS窗口，其中，所述第一指示信息包括所述DRS传输窗口的长度指示信息 和所述DRS传输窗口的起始位置指示信息中的至少一项。
可选地，终端设备根据预设规则确定DRS传输窗口。
可选地，终端设备接收网络设备发送的第二指示信息。所述终端设备根据接收的第二指示信息确定所述COT窗口，其中，所述第二指示信息包括所述COT窗口的长度指示信息、时隙结构指示信息和所述COT对应的信道接入优先级指示信息中的至少一项，其中，所述COT对应的信道接入优先级用于确定所述COT窗口的长度。
应理解，本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
在本申请实施例中，网络设备可以通过免授权载波向终端设备发送第一指示信息和/或第二指示信息，也可以通过授权载波向终端设备发送第一指示信息和/或第二指示信息。相应地，终端设备可以通过免授权载波接收网络设备发送的第一指示信息和/或第二指示信息，也可以通过授权载波接收第一指示信息和/或第二指示信息。
免授权频谱上的LBT方式可以包括LBE的信道接入设备类型和FBE的信道接入设备类型。其中，LBE指通信设备可以在业务到达后进行免授权频谱上的信道检测，并在信道检测成功后开始信号的发送。FBE指通信设备可以周期性地进行信道检测，并且可能用于业务发送的信道资源也是周期性出现的。
可选地，网络设备或终端设备在第一载波上开始传输前，需要先进行LBT，并在LBT成功后进行下行或上行传输。
可选地，在本申请实施例中，高层配置参数包括无线资源控制(Radio Resource Control，RRC)信息或媒体接入控制(Media Access Control，MAC)控制单元(Control Element，CE)信息。
可选地，在本申请实施例中，第一指示信息可以是高层配置参数。
可选地，在本申请实施例中，第二指示信息可以是物理层信令和/或高层配置参数。

可选地，在本申请实施例中，在DRS传输窗口内的SSB可以有多个候选位置，每个候选位置可以认为是一个SSB候选资源。终端设备可以根据Q值确定该多个SSB候选位置中至少两个SSB候选位置的QCL关系，并根据该QCL关系确定SSB的接收。网络设备在DRS传输窗口内发送SSB时，可以进行多次LBT尝试，并且在LBT成功后可以通过该多个候选位置中根据该QCL关系确定获得信道使用权的至少一个候选位置进行SSB传输。其中，Q的取值范围为{1,2,4,8}。其中，该多个SSB候选资源是为了给SSB的传输提供更多的传输机会，实际发送的SSB的个数可以小于SSB的候选资源的个数。
具体地，终端设备可以假设具有相同QCL关系的SSB候选位置上发送的SSB具有相同的QCL关系，或者说，如果网络设备在具有相同QCL关系的SSB候选位置上发送SSB，那么网络设备应该使用相同的波束(beam)。可选地，mod(A，Q)相同的SSB候选位置具有相同的QCL关系，其中，A为SSB候选位置的索引或A为SSB的索引。可选地，Q值为网络设备指示 给终端设备的或Q值为预设的。
