Description

通信方法、装置、电子设备以及存储介质 技术领域
本公开涉及通信领域，尤其涉及一种通信方法、装置、电子设备以及存储介质。
背景技术
随着大规模无线电子设备的使用，无线电频谱资源显得越来越紧张。如何更加合理高效地使用频谱资源，一直是无线通信设计首先需要考虑的问题。
先听后说(Listen Before Talk，简称LBT)或有时称为发射前听(Listen Before Transmit，简称LBT)，是无线电通信中使用的一种技术，无线电发射机在开始传输前首先感知其无线电环境。无线电设备可以使用LBT来查找没有被其它设备占用的频谱资源。也就是说设备必须首先监听想用频率/信道的信号，来检查该频率/信道是否被其它设备占用，如果没有被其它设备使用，则使用该频率/信道。
LBT技术在一定程度上解决了频谱使用的问题。但是，LBT只是解决了自身的信道使用问题，当需要使用频谱资源的设备数量很多时，需要搜索多个信道乃至特定频谱内的所有信道来搜索没有被其它设备使用的信道，搜索效率低下，从而导致信道利用率的急剧降低。
因此，如何提升信道资源的利用率，成为亟需解决的问题。

附图说明
为了更清楚地说明本公开实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
需要说明的是，本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本公开的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
请参见图1，图1是本公开实施例提供的一种通信方法的流程示意图。该方法可以由任一电子设备执行，具体可以是任一需要发送信息的设备(可 以称为发送设备)，其中，发送的信息可以是数据，也可以是控制信息、信令等，对于发送的信息的具体类型本公开实施例不做限定。发送设备可以是基站或者用户设备，或者一种无线电设备，或者一种无线发射设备，或者其他需要进行数据发送的设备，数据发送设备可以接收第一信息，上述第一信息用于指示空闲的信道；基于上述第一信息所指示的空闲的信道发送信息。
如图1所示，本公开实施例提供的通信方法可以包括如下步骤：
步骤S101、接收第一信息，上述第一信息用于指示空闲的信道。
步骤S102，基于上述第一信息所指示的空闲的信道发送信息。
可选的，上述空闲的信道，也可以说成是空闲的信道资源、空闲的信道还可以称为空闲的信道资源、没有被占用的信道、没有被占用的信道资源、未被占用的信道、未被占用的信道资源、空闲状态的信道、空闲状态的信道资源等。其中，信道资源具体可以为时域资源和/或频域资源，例如，信道所占用的频谱资源。
上述第一信息本质上是一种指示信息，该第一信息能够用于指示空闲的信道，也可以描述成用于指示空闲的信道集合，该信道集合可以对应至少一个信道。该第一信息还可以称为第一指示信息等。其中，通过第一信息实现空闲的信道的指示的具体方式，本公开实施例不做限定，如第一信息可以是显式的指示信息，通过解析第一信息即可以知晓空闲的信道，第一信息也可以是隐式的指示信息，发送设备在接收到该信息之后，可以基于该信息根据预先约定的方式确定出空闲的信道。
对于本领域技术人员而言清楚的是，在实际应用中，对于信息的发送，一般是对信息经过编码之后再发送的，相应的，发送设备在接收上述第一信息之后，可以通过相对应的解码方式对该信息进行解码，得到其中所包含的内容。
需要说明的是，本公开实施例中所涉及的各种信息的名称只是示意性的，并不是唯一的，也可以采用其他名称。同样的，上述空闲的信道的说法本公开实施例也不做限定。
可选的，若数据发送设备是基站，则基站需要基于空闲的信道发送信息；若数据发送设备是用户设备，则用户设备需要基于空闲的信道发送信息。若数据发送设备是其他无线电设备，则无线电设备需要基于空闲的信道发送信 息。
其中，上述信息可以理解为数据发送设备想要发送的信息。上述信息可以为调度/控制信息，还可以为数据，在此不作限定。
在一种可选的实施例中，对于上述步骤S102，即基于第一信息所指示的空闲的信道发送信息，可以按照以下步骤实施：
步骤S1021，从上述第一信息所指示的空闲的信道中选择一个信道；
步骤S1022，基于所选择的信道发送信息。
其中，对于从空闲的信道中选择一个信道的具体实现方式，本公开实施例不做限定。可选的，可以从第一信息所指示的空闲的信道中选择出其中任意一个信道。
例如，在一种可选的实施例中，上述从上述第一信息所指示的空闲的信道中选择一个信道，包括：从上述第一信息所指示的空闲的信道中随机选择一个信道。
对于从空闲的信道中选择一个信道的具体实现方式，可以是从上述第一信息所指示的空闲的信道中随机选择一个信道。
在一种可选的实施例中，上述基于所选择的信道发送信息，包括：响应于所选择的信道未被占用，通过所选择的信道发送信息。
在实际应用中，为了避免不同的发送设备发生资源冲突，一个发送设备在发送信息之前，需要确定其所选择的信道是空闲的，即未被其他设备占用的，因此，在通过所选择的信道发送信息之前，可以首先确定所选择的信道是否被占用，如果未被占用，则可以通过该信道发送信息，以避免由于资源冲突导致信息发送失败。
其中，确定信道是否被占用的具体实现方式，本公开实施例不做限定，可以采用现有任一确定信道是否被占用的方式，例如，对于任一电子设备，其在需要使用某一信道或信道资源发送信息时，可以广播发送一信息，通过该信息告知其他设备其占用了某个信道或信道资源，则其他设备可以通过该信息知晓哪个信道或者信道资源被其他设备占用了。
基于本公开实施例所提供的方案，通过接收到的第一信息所指示的空闲的信道来发送信息，避免了现有技术中通过搜索多个信道乃至特定频谱内的 所有信道，来确定空闲的信道的方式，可以直接依据第一信息的指示确定空闲的信道，提高了确定空闲的信道的效率，进而提高了信道资源的利用率。
当发生所选择的信道被占用的情况时，可以通过以下两种可选方式来解决：
方式1：该通信方法还可以包括：
响应于所选择的信道被占用，接收第二信息，第二信息用于指示空闲的信道；
基于第二信息所指示的空闲的信道，发送信息：
也就是说，在上述选择的信道被其他设备占用时，可以接收一个第二信息，基于该第二信息重新确定空闲的信道，可以理解的是，该第二信息和第一信息的本质是相同的，只是两者的接收时机不同而言，两者都是用于指示空闲的信道的信息。可选的，该第二信息还可以称为第二指示信息等。
第一信息和第二信息所指示的空闲的信道可能相同，也可能不同。
在实际应用中，信道的被占用情况是会随时变化的，当所选择的信道被占用时，为了保证获取的信息的实时性，发送设备可以重新接收第二信息，根据重新接收得到的该第二信息中所指示的空闲的信道进行信息的发送，其中，基于第二信息所指示的空闲信道发送信息的方式与基于第一信息所指示的空闲信道发送信息的方式相同，在此不再赘述。
对于如何从第二信息所指示的空闲的信道中选择中要发送信息的信道，可以参考步骤S1021的具体实现方式，如通过随机选择的方式，选择出一个信道来发送想要发送的信息。
需要说明的是，当基于第二信息所指示的空闲的信道发送信息仍然发生被占用的情况时，还可以重新执行上述步骤203-步骤204，即在所选择的信道被占用时，可以重新接收用于指示空闲的信道的信息，基于重新接收的信息所指示的空闲的信道，进行信息的发送。
通过本实施例，当发生所选择的信道被占用的情况时，可以重新接收一个新的第二信息，然后基于该第二信息所指示的空闲的信道来发送信息，避免了由于所选择信道被占用，而无法发送信息或者发送信息失败的情况，并且，由于第二信息中所指示的空闲的信道是新的空闲的信道，从新的空闲的信道中选择信道来发送信息，提高了信息发送的成功率。
方式2：上述基于所选择的信道发送信息，可以包括：
响应于所选择的信道被占用，从上述第一信息所指示的空闲的信道中除上述所选择的信道之外的信道中选择一个信道；
基于重新选择的信道发送信息。
作为可选方式，当选择的信道被别的想要发送信息的设备占用时，可以从第一信息所指示的空闲的信道中，再重新选择一个除了已经选择过的信道之外的信道。其中，对于如何从第一信息所指示的空闲的信道的除所选择的信道之外的信道中选择一个信道来的方式，可以参考步骤S1021的具体实现方式，如通过随机选择的方式，选择出一个信道来发送想要发送的信息。
作为一个示例，假设第一信息所指示的空闲的信道有10个分别为，信道1、信道2、信道3……信道10。第一次选择的信道为信道3，通过信道3发送信息时，发现信道3被占用，此时，可以从剩余的除了信道3之外的其他9个信道中再选择一个信道，如选择了信道6，此时，可以通过信道6来发送信息。
可理解，上述仅为一种示例，本实施例在此不作限定。
基于从第一信息所指示的空闲信道中除被占用的其他的信道中所重新选择的信道来发送信息。例如，通过上述信道6发送信息。当然，如果重新选择的信道也被占用，则可以采用再次重新选择一个其他的空闲信道，或者是重新接收用于指示空闲的信道的信息，基于再次接收到的信息所指示的空闲的信道进行信息的发送。
通过本实施例，当发生所选择的信道被占用的情况时，可以从第一信息所指示的空闲的信道的其他剩余的信道中选择一个信道来发送信息，避免了由于所选择信道被占用，而无法发送信息，提高了发送信息的成功率。
需要说明是，本公开实施例所提供的上述在所选择信道被占用时的两种可选实施方式是可以单独实施，也可以组合实施的，例如，可以设置一重复选择的次数阈值，如果连续重新选择空闲的信道的次数大于或等于该次数阈值，则可以执行重新接收用于指示空闲的信道的信息，基于该重新接收的信息所指示的空闲的信道进行信息的发送，在连续重新选择空闲的信道的小于或等于该次数阈值时，则可以执行上述重新选择空闲的信道的步骤，基于重 新选择的空闲的信道进行信息的发送。再例如，可以设置一时间阈值，在当前时间距离第一信息接收到的时间之间的时差大于或等于时间阈值时，需要重新接收用于指示空闲的信道的信息，基于该重新接收的信息所指示的空闲的信道进行信息的发送，在当前时间距离第一信息接收到的时间之间的时差小于或等于时间阈值时，可以从第一信息所指示的空闲信道中除已被其他设备占用的信道之外的信道中重新选择一个，基于重新选择的信道发送信息。
本公开的可选实施例中，上述接收第一信息，可以包括：
接收第一设备发送的第一信息，第一信息所指示的空闲的信道是第一设备通过以下方式确定的：
接收各第二设备发送的信号信息，根据接收到的信号信息确定空闲的信道。
对于第一设备来说，可以通过以下方式来确定空闲的信道，第二设备采集信号信息，然后向第一设备发送信号信息，当第一设备接收到第二设备发送的信号信息时，可以根据接收到的信号信息来确定空闲的信道。
其中，对于第一设备来说，可以周期性的或者非周期性的接收来自第二设备的信号信息，然后不断地根据信号信息确定空闲的信道，并不断地根据接收到的新的信号信息确定用于指示空闲的信道信息，保证用于指示空闲的信道的信息是最新的。
在一种可选的实施例中，上述第二设备发送的上述信号信息包括以下至少一项：信号的信号强度、信号类型、信号特征。
第二设备可以采集信号信息，信号信息可以包括采集到的信号的信号强度，信号强度用于表征信号的强弱。
信号信息还可以包括采集到的信号的信号类型，该信号的信号类型可以为第五代移动通信技术(5th generation mobile networks或5th generation wireless systems、5th-Generation，简称5G)5G信号、第四代移动通讯技术(the 4generation mobile communication technology，简称4G)4G信号、第三代移动通讯技术(The 3rd Generation Telecommunication，简称3G)3G信号、第二代手机通信技术(t 2-Generation wireless telephone technology，简称2G)2G信号、无线保真(Wireless-Fidelity，简称WiFi)WiFi信号，等等。
信号信息还可以包括采集到的信号的信号特征，信号特征用于表征信号的特征信息。例如，采集到的信号是5G信号中的同步信号(Synchronous signal)中的某一种，其中，同步信号就是给需要同步处理信息的机器设备提供相同时间参考的信号，是同一载体内同时发出的多个信号源。
当第一设备接收到第二设备采集的信号信息时，可以根据信号强度、信号类型、信号特征中的至少一项确定出空闲的信道。
在一种可选的实施例中，上述接收第一信息，包括：接收广播信息，上述广播信息中包含上述第一信息。
对于第一信息来说，可以通过第一设备将该第一信息通过广播的方式进行广播。第一设备可以在专用的广播信道进行统一广播该第一信息，在广播该第一信息时，可以按照一定功率发射，以保证特定空间内的所有设备能够接收到该广播信息。其中，特定空间可以理解为，一个房间，一个小区，一栋楼，一个商场等等，在此不作限定。
上述第二设备可以理解为一种能够接收信号的接收器(或者还可以称为频谱感知点)，该第二设备能够对该第二设备周边的频谱使用情况进行感知，第二设备能够将感知到的信号信息传输到负责广播的第一设备。其中，第二设备可以采用有线传输或者无线传输的方式，将感知到的信号信息传输到负责广播的第一设备。
在一种可选的实施例中，本公开实施例的方法还可以包括：获取空闲的信道中各信道对应的第二设备的位置信息；相应的，上述基于第一信息所指示的空闲的信道发送信息，可以包括：基于上述各信道对应的第二设备的位置信息，从上述第一信息所指示的空闲的信道中确定目标信道；基于上述目标信道发送信息。
可选的，可以获取空闲的信道中各个信道对应的第二设备的位置信息，然后基于各个信道对应的第二设备的位置信息，从第一信息所指示的空闲的信道中确定出一个目标信道，然后，通过该目标信道来发送信息。
在获取空闲的信道的各信道对应第二设备的位置信息时，可以有多种获取方式，具体有：
方式1：第二设备向第一设备发送信号信息时，可以将位置信息同时发送给第一设备。第一设备可以将位置信息单独发送给想要发送信息的设备。 或者，第一信息中可以包括第二设备的位置信息，第一设备在发送第一信息时，能够向想要发送信息的设备发送位置信息。
方式2：在实际应用中，对于第二设备的位置信息，第一设备预先是知晓的，在第一设备向想要发送信息的设备发送第一信息时，可以直接将第二设备的位置信息发送出去。
方式3：第一信息中可以包括第二设备的标识信息，想要发送信息的设备可以通过第二设备的标识信息，采用查表的方式，查询得到第二设备的位置信息。
在按照上述方式得到空闲的信道的各信道对应的第二设备的位置信息后，可以依据第二设备的位置信息，从中选择出一个目标信道，例如，可以选择距离想要发送信息的设备距离近的第二设备对应的目标信道。可以依据第二设备的位置信息避开信号干扰强的位置，如电厂等。可理解，对于如何依据位置信息确定目标信道的方式，在此不作限定。
在一种可选的实施例中，还可以按照以下方式确定目标信道，上述方法由信息发送设备执行，上述基于上述各信道对应的第二设备的位置信息，从上述第一信息所指示的空闲的信道中确定目标信道，包括：基于上述发送设备的位置信息和上述各信道对应的第二设备的位置信息，从上述第一信息所指示的空闲的信道中确定目标信道。
可选的，可以依据发送设备(即想要发送信息的设备)的位置信息和各信道对应的第二设备的位置信息，得到发送设备和各信道对应的第二设备的距离，从第一信息所指示的空闲的信道中选择距离最近的信道作为目标信道。
通过本实施例，可以通过第一设备接收第二设备采集的信号信息，然后由第一设备基于信号信息计算出空闲的信道，基于空闲的信道，通过广播的方式发送第一信息，当想要发送信息的数据发送设备接收到第一信息时，可以直接读取第一信息，然后基于第一信息所指示的空闲的信道来发送信息。当想要发送信息的设备数量较多、且同时使用时，这些大规模的想要发送信息的设备无需搜索多个信道，只需读取第一设备通过专用的广播信道发送的第一信息，即可获取到空闲的信道，然后基于空闲的信道发送信息，使得多个想要发送信息的设备对信道资源能够更加高效合理地使用，提高了信道资源的利用率。
参见图2，图2是本公开实施例提供的一种通信方法的流程示意图，如图2所示，该方法可以应用于第一设备，主要包括以下步骤：
