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。
在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
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识别下行传输的方法的流程图，图2是根据一示例性实施例示出的一种识别下行传输的方法的应用场景图；该识别下行传输的方法可以用于基站；如图1所示，该识别下行传输的方法可以包括以下步骤110-120：
在步骤110中，设置用于识别下行传输的指示信息。
本公开实施例中，针对非授权频谱，引入了LBT(Listen Before Talk，先听后说)的机制。也就是说数据发送端在有数据需要发送时，需要先检测信道是否空闲， 只有信道处于空闲的状态后，才可以发送数据。
当数据发送端为基站，该基站通过了LBT信道检测并成功获取信道后，将会向终端发送数据，终端需要在相应的位置上发送针对该数据的HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)反馈信息。
由于有的业务对时延要求较高，所以要求终端在COT(Channel Occupancy Time，信道占用时间)内就进行HARQ的反馈。但是，一个COT中可能存在多个上下行切换点，在这种情况下，为了便于终端识别不同的下行传输，基站可以先设置用于识别下行传输的指示信息，再将指示信息发送至终端，这样终端就可以根据该指示信息识别不同的下行传输，使得终端在测量的时候，比如：CSI(Channel State Information，信道状态信息)测量，可以得到准确的测量结果。
在一实施例中，所述指示信息可以包括第一指示状态或第二指示状态，所述第一指示状态用于表征当前的下行传输没有发生变化，所述第二指示状态用于表征当前的下行传输是一个新的下行传输。比如：“0”代表第一指示状态，“1”代表第二指示状态。其中，当前的下行传输没有发生变化，可以表明当前的下行传输与上一个下行传输属于同一COT内，比如：上一个下行传输属于COT1，且当前的下行传输仍然属于COT1；当前的下行传输是一个新的下行传输，可以表明当前的下行传输与上一个下行传输的属于不同COT内，比如：上一个下行传输属于COT1，但当前的下行传输属于COT2。
在一实施例中，所述指示信息可以包括用于表征当前下行传输的编号信息。其中，编号信息可以是COT的编号。
在步骤120中，将指示信息发送至终端，以使终端根据该指示信息识别下行传输。
本公开实施例中，基站将指示信息发送至终端，其目的是让终端根据该指示信息识别不同的下行传输是否属于同一个COT。
在一实例性场景中，如图2所示，包括基站和终端。基站可以先设置用于识别下行传输的指示信息，再将指示信息发送至终端，这样终端就可以根据该指示信息识别不同的下行传输，使得终端在测量的时候可以得到准确的测量结果。
由上述实施例可见，可以通过设置用于识别下行传输的指示信息，将指示信息发送至终端，以使终端根据该指示信息识别下行传输，从而提高了识别下行传输的准 确度，还提高了识别下行传输的效率。
图3是根据一示例性实施例示出的另一种识别下行传输的方法的流程图，该识别下行传输的方法可以用于基站；该方法建立在图1所示方法的基础上，在执行步骤120时，如图3所示，可以包括以下步骤310-320：
在步骤310中，设置显式指示信令，该显式指示信令中包括用于识别下行传输的指示信息。
本公开实施例中，显式指示信令可以指的是能够显式指示用于识别下行传输的指示信息。
在一实施例中，所述显式指示信令可以为下行控制信令；所述指示信息位于所述下行控制信令的固定的或可配置的信息域，且所述信息域具有固定的或可配置的信息域长度。
在步骤320中，将显式指示信令发送至终端，以使终端从该显式指示信令中获取用于识别下行传输的指示信息。
本公开实施例中，基站可以通过显式指示信令将用于识别下行传输的指示信息告知终端。如图3A所示，在每个COT内的不同的下行传输，基站可以通过一个携带了用于识别下行传输的指示信息的下行控制信令发送给终端，终端基于该指示信息来识别不同的下行传输。比如：COT1上各个下行传输1的指示信息的内容可以是：COT1的编号即1；COT2上各个下行传输2的指示信息的内容可以是：COT2的编号即2。
由上述实施例可见，可以通过显示指示的方式将指示信息告知终端，从而提高了指示信息传输的灵活性，还提高了指示信息传输的可靠性。
图4是根据一示例性实施例示出的另一种识别下行传输的方法的流程图，该识别下行传输的方法可以用于基站；该方法建立在图1所示方法的基础上，在执行步骤120时，如图4所示，可以包括以下步骤410-420：
在步骤410中，按照设定规则设置隐式指示信令，该隐式指示信令中包括用于表征指示信息的加扰序列。
本公开实施例中，隐式指示信令可以指的是能够隐式指示用于识别下行传输的指示信息。该隐式指示信令可以是一个通过用于表征指示信息的加扰序列进行加扰后的下行控制信令，其目的是终端可以根据加扰序列来确定对应的指示信息。
在一实施例中，所述设定规则中可以包括至少一个指定加扰序列和指定指示信息之间的对应关系。其中，设定规则可以是通信协议规定的，或基站配置的、且通过指定信令通知终端的。
比如：加扰序列1用于表征“0”，加扰序列2用于表征“1”。
在一实施例中，该识别下行传输的方法还可以包括：
通过预先定义的或者信令通知的方式将所述设定规则发送至所述终端。
在步骤420中，将隐式指示信令发送至终端，以使终端根据该隐式指示信令包括的加扰序列确定用于识别下行传输的指示信息。
由上述实施例可见，可以通过隐式指示的方式将指示信息告知终端，从而降低了指示信息的信令开销。

在一实施例中，所述COT配置信息包括以下至少一项：当前COT起始位置和当前COT在时间上的长度信息；或当前COT起始位置和当前COT结束位置；或当前COT起始位置和当前COT在时间上的长度信息、以及用于测量的导频的功率信息；或当前COT起始位置和当前COT结束位置、以及用于测量的导频的功率信息。
在步骤520中，将COT配置信息发送至终端，以使终端根据该COT配置信息确定用于识别下行传输的指示信息。
本公开实施例中，基站可以在每个COT开始之前将COT配置信息发送至终端，也可以预先将每个COT的配置信息均通知了终端，这样终端可以基于基站通知的COT配置信息，隐式的识别不同的下行传输。比如：如图5A所示，在COT1开始之前，基站会将与COT1对应的COT配置信息发送至终端；同理，在COT2开始之前，基站会将与COT2对应的COT配置信息发送至终端。
由上述实施例可见，可以通过COT配置信息来隐式告知终端用于识别下行传输的指示信息，从而丰富了识别下行传输的实现方式，进而提高了识别下行传输的实用性。

在步骤610中，接收基站发送的用于识别下行传输的指示信息。
在步骤620中，根据该指示信息识别下行传输。
在一实施例中，所述指示信息包括第一指示状态或第二指示状态，所述第一指示状态用于表征当前的下行传输没有发生变化，所述第二指示状态用于表征当前的下行传输是一个新的下行传输；在执行步骤620时，可以包括：
若所述指示信息为所述第一指示状态，则确定当前的下行传输没有发生变化。也就是说当前的下行传输与上一个下行传输属于同一COT
若所述指示信息为所述第二指示状态，则确定当前的下行传输是一个新的下行传输。也就是说当前的下行传输与上一个下行传输属于不同的COT。
在一实施例中，所述指示信息包括用于表征当前下行传输的编号信息；在执行步骤620时，可以包括：
若当前下行传输的编号信息与上一个下行传输的编号信息相同，则确定当前的下行传输没有发生变化。也就是说当前的下行传输与上一个下行传输属于同一COT。
若当前下行传输的编号信息与上一个下行传输的编号信息不同，则确定当前的下行传输是一个新的下行传输。也就是说当前的下行传输与上一个下行传输属于不同的COT。
由上述实施例可见，可以通过接收基站发送的用于识别下行传输的指示信息，并根据该指示信息识别下行传输，从而提高了识别下行传输的准确度，还提高了识别下行传输的效率。

在步骤920中，根据该COT配置信息确定用于识别下行传输的指示信息。
如图5A所示，在COT1开始之前，基站会将与COT1对应的COT配置信息发 送至终端，这样终端可以根据该COT配置信息识别COT1内的3个下行传输1；同理，在COT2开始之前，基站会将与COT2对应的COT配置信息发送至终端，这样终端可以根据该COT配置信息识别COT2内的3个下行传输2。
由上述实施例可见，可以根据COT配置信息确定用于识别下行传输的指示信息，从而丰富了识别下行传输的实现方式，进而提高了识别下行传输的实用性。
