具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
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)系统、先进的长期演进(advanced long term evolution，LTE-A)系统、新无线(new radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum，NR-U)系统、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、无线局域网(wireless local area networks，WLAN)、无线保真(wireless fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(device to device，D2D)通信，机器到机器(machine to machine，M2M)通信，机器类型通信(machine type communication，MTC)，以及车辆间(vehicle to vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
示例性的，本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与终端120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端进行通信。可选地，该网络设备110可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来通信系统中的网络设备等。
该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端120。作为在此使用的“终端”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端或者未来演进的PLMN中的终端等。

可选地，5G通信系统或5G网络还可以称为新无线(New Radio，NR)系统或NR网络。
图1示例性地示出了一个网络设备和两个终端，可选地，该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端，本申请实施例对此不做限定。
可选地，该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。

应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。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。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
非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。
为了让使用非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，一些国家或地区规定了使用非授权频谱必须满足的法规要求。例如，通信设备遵循先听后说(Listen Before Talk，LBT)原则，即通信设备在非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，该通信设备才能进行信号发送；如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。为了保证公平性，在一次传输中，通信设备使用非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 Occupancy Time，MCOT)。
以下对R15 NR系统中的DCI格式2_0和R16 NR-U系统中的DCI格式2_0进行描述。
●R15 NR系统中的DCI格式2_0
NR系统中时隙格式指示(Slot Format Indicator，SFI)信息是通过公共PDCCH(GC-PDCCH)传输的，对应的下行控制信息(Downlink Control Information，DCI)格式是DCI格式2_0。终端设备可以被配置检测DCI格式2_0，也可以不被配置检测DCI格式2_0。一个DCI格式2_0中可以包括一个或一组小区的SFI信息，DCI格式2_0对应的循环冗余校验(Cyclic Redundancy Check，CRC)是通过SFI-RNTI扰码的，这里，SFI-RNTI可以通过高层进行配置。
DCI格式2_0传输的DCI信息如下：SFI 1，SFI 2，。。。，SFI N。其中，一个SFI-index域的大小最大例如可以为9比特，用于指示一个时隙格式组合标识(ID)。DCI格式2_0的大小是高层配置的，最大比特数为128比特。对于每个小区，终端设备会被提供/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(其中该集合中的每个时隙格式组合包括：时隙格式组合标识和一个或多个时隙格式指示，该时隙格式组合标识和该一个或多个时隙格式指示一一对应)、参考子载波间隔(如果是非配对频谱工作方式，提供正常上行载波和补充上行载波对应的第一参考子载波间隔配置和第二参考子载波间隔配置；如果是配对频谱工作方式，提供下行BWP和上行BWP对应的第一参考子载波间隔配置和第二参考子载波间隔配置)。
终端设备根据SFI-RNTI检测到DCI格式2_0后，如果想确定某个小区对应的时隙格式，可以根据高层配置的参数找到该小区的小区标识以及确定该小区对应的SFI-index域在检测到的DCI格式2_0中的起始位置，然后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对应的时隙格式。
一般，终端设备通过上述方式确定的时隙格式指示的时间长度大于或等于用于承载DCI格式2_0的物理下行控制信道(Physical Downlink Control Channel，PDCCH)的检测周期。也就是说，终端设备可能在两个不同的时间收到两个SFI，这两个SFI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这两个SFI指示的时隙格式相同。
●R16 NR-U系统中的DCI格式2_0
对于一组服务小区中的每个服务小区，终端设备可以被提供以下至少一种信息：
服务小区的小区标识；
SFI-index域在DCI格式2_0中的位置；
时隙格式组合集合，其中该时隙格式组合集合中的每个时隙格式组合包括：一个或多个时隙格式指示、时隙格式组合标识和该一个或多个时隙格式指示的映射关系，其中，DCI格式2_0中的SFI-index域用于指示时隙格式组合标识；
对于非配对频谱工作方式的第一参考子载波间隔配置，可选地，如果被配置了补充上行载波，还提供补充上行载波对应的第二参考子载波间隔配置；
对于配对频谱工作方式，提供了下行BWP对应的第一参考子载波间隔配置和上行BWP对应的第二参考子载波间隔配置；
可用RB集合指示域在DCI格式2_0中的位置，可用RB集合指示域中的每个比特与小区的RB集合中的每个RB集合具有一一映射关系，其中，如果该比特为第一状态例如指示为“0”，表示对应的RB集合可用于下行接收，如果该比特为第二状态例如指示为“1”，表示对应的RB集合不能用于下行接收。可用RB集合指示域在指示的信道占用长度内有效，或者说，该RB集合在指示的信道占用长度结束前可用于下行接收或不能用于下行接收。
信道占用长度(Channel Occupancy duration)指示域在DCI格式2_0中的位置，信道占用长度指示域用于指示从终端设备检测到DCI格式2_0的时域位置例如时隙开始该小区剩余的信道占用长度。如果终端设备没有被配置信道占用长度指示域，那么该小区剩余的信道占用长度包括从终端设备检测到DCI格式2_0的时域位置例如时隙开始根据SFI-index域指示的时隙格式确定的时隙个数。这里，信道占用长度指示域也可以称为信道占用时间长度(COT duration)指示域。
搜索空间集合组切换指示域在DCI格式2_0中的位置，搜索空间集合组切换指示域用于指示小区上配置的两个搜索空间集合组中的一个搜索空间集合组，以使终端设备根据指示的搜索空间集合组在该小区上进行PDCCH检测。
NR-U系统中，对于一个服务小区，在DCI格式2_0包括的信息域中，可用RB集合指示域、信道占用长度指示域和搜索空间集合组切换指示域都是可配置的。然而，对于DCI格式2_0中部分指示域未被配置的情况，如何规定终端设备的数据传输行为，目前还没有结论。为此，提出了本申请实施例的以下技术方案。
本申请实施例提出了以下几种DCI格式的接收方法，以下具体对其进行描述。

所述终端设备不期望所述DCI格式2_0中未被配置时隙格式指示域；或，

3、如果终端设备被配置检测DCI格式2_0，其中DCI格式2_0中既不包括SFI-index域也不包括信道占用长度指示域，那么终端设备根据预设值确定信道占用时间的长度，其中该预设值可以是预设的例如标准预设的或网络设备配置的。

3、如果终端设备的预配置下行资源被配置在一个RB集合中，且终端设备被配置检测DCI格式2_0，那么终端设备只在收到DCI格式2_0且该DCI格式2_0(例如通过SFI指示或信道占用长度指示)指示该RB集合中的预配置下行资源在网络设备的信道占用长度内的情况下才可以进行该预配置下行信道的接收；或，如果终端设备的预配置下行资源被配置在一个RB集合中，且终端设备被配置检测DCI格式2_0，如果终端设备没有收到DCI格式2_0或终端设备收到DCI格式2_0但该DCI格式2_0(例如通过SFI指示或信道占用长度指示)没有指示该RB集合中的预配置下行资源在网络设备的信道占用长度内，那么终端设备不进行该预配置下行信道的接收。
4、如果终端设备的预配置下行资源被配置在一个RB集合中，那么终端设备只在确定该RB集合中的预配置下行资源在网络设备的信道占用长度内的情况下才可以进行该预配置下行信道的接收；或，如果终端设备的预配置下行资源被配置在一个RB集合中，但终端设备不能确定该RB集合中的预配置下行资源在网络设备的信道占用长度内，那么终端设备不进行该预配置下行信道的接收。
