具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉 及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。

应当理解，尽管在本公开可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开范围的情况下，指示信息也可以被称为第二信息，类似地，第二信息也可以被称为指示信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
图1是根据一示例性实施例示出的一种信道指示方法的流程图，图2是根据一示例性实施例示出的一种信道指示方法的应用场景图；该信道指示方法可以用于在非授权频段上工作的基站；如图1所示，该信道指示方法包括以下步骤110-130：
在步骤110中，确定一个或多个通过信道检测的第一信道检测子带。
本公开实施例中，基站可以对多个信道检测子带进行信道检测，得到信道检测结果，该信道检测结果中可能包括一个或多个通过信道检测的第一信道检测子带。其中，这里的第一信道检测子带指的是已经通过信道检测的信道检测子带。
另外，各个通过信道检测的第一信道检测子带可以是一个非授权载波上配置的多个带宽部分、或多个非授权载波、或多个非授权载波上配置的多个带宽部分。
在步骤120中，生成信道指示信号，该信道指示信号用于指示通过信道检测的各个第一信道检测子带。
本公开实施例中，信道指示信号用于指示哪些信道检测子带已经通过了信道检测。
在一实施例中，上述步骤120中的信道指示信号可以包括第一下行信号和第一下行控制信令；所述第一下行信号用于指示终端需要检测后续发送的所述下行控制信令，所述第一下行控制信令中包括用于表征各个所述第一信道检测子带的标识信息。其具体实现过程可参见图3所示实施例。
在一实施例中，上述步骤120中的信道指示信号可以包括第二下行信号，所述第二下行信号的序列值用于指示通过信道检测的各个所述第一信道检测子带。其具体实现过程可参见图4所示实施例。
在一实施例中，上述步骤120中的信道指示信号可以包括第三下行信号，所述第三下行信号的发送位置用于指示通过信道检测的各个所述第一信道检测子带。其具体实现过程可参见图5所示实施例。
在一实施例中，上述步骤120中的信道指示信号可以包括第二下行控制信令，所述第二下行控制信令的指定信息域上包括用于显式指示各个所述第一信道检测子带的第一指示信息、或所述第二下行控制信令的CRC(Cyclical Redundancy Check，循环校验)的加扰序列上包括用于隐式指示各个所述第一信道检测子带的第二指示信息。其具体实现过程可参见图6所示实施例。
在步骤130中，将信道指示信号发送至终端，以使终端根据信道指示信号确定通过信道检测的各个第一信道检测子带。
本公开实施例中，基站可以通过信道指示信号来告知终端哪些信道检测子带已经通过了信道检测，这样终端就可以在这些通过信道检测的信道检测子带上进行数据传输。
在一实例性场景中，如图2所示，包括基站11和终端12。基站11在确定一个或多个通过信道检测的第一信道检测子带后，可以生成信道指示信号，该信道指示信号用于指示通过信道检测的各个第一信道检测子带，以及将信道指示信号发送至终端12；终端12接收到基站11发送的信道指示信号后，可以根据该信道指示信号确定通过信道检测的各个第一信道检测子带，并在各个第一信道检测子带上进行数据传输。
在本公开中，基站11可以是一种部署在接入网中用以为终端12提供无线通信功能的装置。基站11可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的***中，具备基站功能的设备的名称可能会有所不同，例如在5G NR***中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本公开实施例中，上述为终端12提供无线通信功能的装置统称为基站。
终端12的数量通常为多个，每一个基站11所管理的小区内可以分布一个或多个终端12。终端12可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴 设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，本公开实施例中，上面提到的设备统称为终端。
由上述实施例可见，在确定一个或多个通过信道检测的第一信道检测子带后，可以生成信道指示信号，该信道指示信号用于指示通过信道检测的各个第一信道检测子带，以及将信道指示信号发送至终端，这样终端就可以根据信道指示信号准确确定通过信道检测的各个第一信道检测子带，从而节省了信道检测能耗，还提高了数据传输性能。
图3是根据一示例性实施例示出的另一种信道指示方法的流程图，该信道指示方法可以用于在非授权频段上工作的基站，并建立在图1所示方法的基础上，所述信道指示信号包括第一下行信号和第一下行控制信令；所述第一下行信号用于指示终端需要检测后续发送的所述下行控制信令，所述第一下行控制信令中包括用于表征各个所述第一信道检测子带的标识信息；在执行步骤130时，如图3所示，可以包括以下步骤310-330：
在步骤310中，确定用于传输第一下行信号和第一下行控制信令的第二信道检测子带，该第二信道检测子带为各个第一信道检测子带、或各个第一信道检测子带中的部分子带。
本公开实施例中，第一下行信号可以为DMRS(Demodulation Reference Signal，解调参考信号)、CSI-RS(Channel State Information Reference Signal，信道状态信息参考信号)或是其他类型的下行信号；第一下行控制信令可以为用来承载公共控制信息的控制信令。
若第二信道检测子带为各个第一信道检测子带，则表明需要在每个第一信道检测子带上发送第一下行信号和第一下行控制信令。如图3A所示，信道检测子带1和信道检测子带3为通过信道检测的第一信道检测子带，则在信道检测子带1和信道检测子带3上发送第一下行信号和第一下行控制信令。
比如：信道检测子带1上发送的第一下行控制信令和信道检测子带3上发送的第一下行控制信令，二者包括的标识信息相同，均为信道检测子带1和信道检测子带3。
又比如：信道检测子带1上发送的第一下行控制信令包括的标识信息为信道检 测子带1；信道检测子带3上发送的第一下行控制信令包括的标识信息为信道检测子带3。
若第二信道检测子带为各个第一信道检测子带中的部分子带，则表明只在这部分子带上均发送第一下行信号和第一下行控制信令。如图3B所示，信道检测子带1、信道检测子带2和信道检测子带3为通过信道检测的第一信道检测子带，但只在信道检测子带1和信道检测子带3上发送第一下行信号和第一下行控制信令。
比如：信道检测子带1上发送的第一下行控制信令和信道检测子带3上发送的第一下行控制信令，二者包括的标识信息相同，均为信道检测子带1、信道检测子带2和信道检测子带3。
又比如：信道检测子带1上发送的第一下行控制信令包括的标识信息为信道检测子带1和信道检测子带2；信道检测子带3上发送的第一下行控制信令包括的标识信息为信道检测子带3。
在步骤320中，在第二信道检测子带的第一位置发送第一下行信号。
在步骤330中，在第二信道检测子带的第二位置发送第一下行控制信令，该第二位置是第一位置后续的另一位置。
上述步骤320中的第一位置和上述步骤330中的第二位置之间的间隔可以是预先定义的或是基站通过信令预先通知下来的。
由上述实施例可见，可以在各个第一信道检测子带的第一位置和第二位置分别发送第一下行信号和第一下行控制信令，也可以在各个第一信道检测子带中的部分子带的第一位置和第二位置分别发送第一下行信号和第一下行控制信令，从而丰富了信道指示的多样性，还提高了信道指示的可靠性。
图4是根据一示例性实施例示出的另一种信道指示方法的流程图，该信道指示方法可以用于在非授权频段上工作的基站，并建立在图1所示方法的基础上，所述信道指示信号包括第二下行信号，所述第二下行信号的序列值用于指示通过信道检测的各个所述第一信道检测子带；在执行步骤130时，如图4所示，可以包括以下步骤410：
在步骤410中，将携带有第二下行信号的信道指示信号发送至终端，以使终端确定第二下行信号的序列值，并根据该第二下行信号的序列值确定各个第一信道检测子带。
在一实施例中，如图4所示，该信道指示方法还可以包括以下步骤420-430：
在步骤420中，获取预设的下行信号序列值与通过信道检测的信道检测子带之间的第一对应关系。
本公开实施例中，第一对应关系中包括预设的下行信号序列值和预设的通过信道检测的信道检测子带，其具体的对应关系可详见图4A所示。如图4A所示，第一下行信号可以为DMRS，预设的下行信号序列值包括DMRS序列1、DMRS序列2、DMRS序列3、DMRS序列4、DMRS序列5、…等，DMRS序列1对应信道检测子带1、DMRS序列2对应信道检测子带2、DMRS序列3对应信道检测子带3、DMRS序列4对应信道检测子带1和2、DMRS序列1对应信道检测子带1和2和3和4、…等。
在步骤430中，将第一对应关系发送至终端，以使终端根据第一对应关系确定第二下行信号的序列值对应的各个第一信道检测子带。
本公开实施例中，针对上述步骤410和步骤430的发送顺序并没有限制，可以同时发送步骤410和步骤430；也可以先发送步骤410、再发送步骤430；还可以先发送步骤430、再发送步骤410。
另外，针对上述步骤420-430中的第一对应关系，若终端可以预先获知而不需要基站通知，比如，该第一对应关系已在协议中给定的，此时基站也可以不再将该第一对应关系发送终端了。
由上述实施例可见，可以利用第二下行信号的序列值来指示通过信道检测的各个第一信道检测子带，并将携带有第二下行信号的信道指示信号发送至终端，这样终端就可以确定第二下行信号的序列值，并根据该第二下行信号的序列值确定各个第一信道检测子带，从而节省了信道指示的信令开销，还提高了信道指示的效率。
图5是根据一示例性实施例示出的另一种信道指示方法的流程图，该信道指示方法可以用于在非授权频段上工作的基站，并建立在图1所示方法的基础上，所述信道指示信号包括第三下行信号，所述第三下行信号的发送位置用于指示通过信道检测的各个所述第一信道检测子带；在执行步骤130时，如图5所示，可以包括以下步骤410：
在步骤510中，将携带有第三下行信号的信道指示信号发送至终端，以使终端确定第三下行信号的发送位置，并根据该第三下行信号的发送位置确定各个第一信道检测子带。
在一实施例中，如图5所示，该信道指示方法还可以包括以下步骤520-530：
在步骤520中，获取预设的下行信号发送位置与通过信道检测的信道检测子带之间的第二对应关系。
本公开实施例中，第二对应关系中包括获取预设的下行信号发送位置和预设的通过信道检测的信道检测子带。比如：第一下行信号可以为DMRS，在一个信道检测子带上的第x个频率位置上检测到了DMRS，就代表信道检测子带1通过了信道检测；在一个信道检测子带上的第y个频率位置上检测到了DMRS，就代表信道检测子带1和2通过了信道检测。其中，x，y可以是一个或是多个值，并且基站需要预先定义或是通过信令通知终端DMRS的发送位置与信道检测结果的对应关系。
在步骤530中，将第二对应关系发送至终端，以使终端根据第二对应关系确定第三下行信号的发送位置对应的各个第一信道检测子带。
本公开实施例中，针对上述步骤510和步骤530的发送顺序并没有限制，可以同时发送步骤510和步骤530；也可以先发送步骤510、再发送步骤530；还可以先发送步骤530、再发送步骤510。
另外，针对上述步骤520-530中的第二对应关系，若终端可以预先获知而不需要基站通知，比如，该第二对应关系已在协议中给定的，此时基站也可以不再将该第二对应关系发送终端了。
由上述实施例可见，可以利用第三下行信号的发送位置来指示通过信道检测的各个第一信道检测子带，并将携带有第三下行信号的信道指示信号发送至终端，这样终端就可以确定第三下行信号的发送位置，并根据该第三下行信号的发送位置确定各个第一信道检测子带，从而节省了信道指示的信令开销，还扩展了信道指示的实现形式。
图6是根据一示例性实施例示出的另一种信道指示方法的流程图，该信道指示方法可以用于在非授权频段上工作的基站，并建立在图1所示方法的基础上，所述信道指示信号包括第二下行控制信令，所述第二下行控制信令的指定信息域上包括用于显式指示各个所述第一信道检测子带的第一指示信息、或所述第二下行控制信令的CRC的加扰序列上包括用于隐式指示各个所述第一信道检测子带的第二指示信息；在执行步骤130时，如图6所示，可以包括以下步骤610：
在步骤610中，将携带有第二下行控制信令的信道指示信号发送至终端，以使 终端根据第二下行控制信令上的第一指示信息或第二指示信息确定各个第一信道检测子带。
由上述实施例可见，可以通过第二下行控制信令来显式指示或隐式指示通过信道检测的各个第一信道检测子带，并将携带有第二下行控制信令的信道指示信号发送至终端，这样终端就可以根据第二下行控制信令上的第一指示信息或第二指示信息确定各个第一信道检测子带，从而提高了信道指示的准确性。
图7是根据一示例性实施例示出的一种信道指示方法的流程图，图2是根据一示例性实施例示出的一种信道指示方法的应用场景图；该信道指示方法可以用于在非授权频段上工作的终端；如图7所示，该信道指示方法包括以下步骤710-720：
在步骤710中，接收基站发送的信道指示信号，该信道指示信号用于指示一个或多个通过信道检测的第一信道检测子带。
本公开实施例中，基站可以通过信道指示信号来告知终端哪些信道检测子带已经通过了信道检测，这样终端就可以在这些通过信道检测的信道检测子带上进行数据传输。其中，这里的第一信道检测子带指的是已经通过信道检测的信道检测子带。
另外，各个通过信道检测的第一信道检测子带可以是一个非授权载波上配置的多个带宽部分、或多个非授权载波、或多个非授权载波上配置的多个带宽部分。
在步骤720中，根据信道指示信号确定通过信道检测的各个第一信道检测子带。
本公开实施例中，由于信道指示信号包括的内容不同，终端可以采用对应的方式确定通过信道检测的各个第一信道检测子带。

(1-1)在各个所述第一信道检测子带接收所述第一下行信号；
(1-2)若接收到所述第一下行信号时，则继续接收所述第一下行控制信令；
此种方式下，由于终端不知道基站在哪个第一信道检测子带发送标识信息，所以终端需要在每个第一信道检测子带均接收第一下行信号，只有接收到第一下行信号，才会确定基站将会在该第一信道检测子带上发送标识信息，故此会继续接收后续的第 一下行控制信令。
与此对应的，在执行步骤720时，可以包括：

(3-2)根据所述第一对应关系确定所述第二下行信号的序列值对应的各个所述第一信道检测子带。
针对上述(3-1)中的第一对应关系的获取方式，可以是接收基站通知的；也可以是终端预先获知的，比如，在协议中给定的。
在一实施例中，上述步骤710中的信道指示信号可以包括第三下行信号，所述第三下行信号的发送位置用于指示通过信道检测的各个所述第一信道检测子带；与此对应的，在执行步骤720时，可以包括：
