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。
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”。
随着通信技术的不断发展，扩展PBCH的必要性越来越强。但是，相关技术中并没有关于扩展PBCH的技术方案，降低了PBCH的通信能力。
在3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)的5G(5th Generation，第五代移动通信技术)第一版中，PBCH有效信息只有32位，考虑到第 一版比较仓促，很多后续扩展没有考虑，因此需要PBCH能够扩展；另一方面3GPP也很明确指出要考虑前向兼容和后向兼容，增加标准的实用性，因此，PBCH扩展不能影响网络和终端的兼容性。
本公开针对上述问题，提出了一种扩展PBCH的方法，在该扩展PBCH的方法中，可以先在PBCH的同步广播块中设置PBCH扩展位，然后通过该PBCH扩展位进行PBCH扩展。其中，PBCH扩展位可以为上述“PBCH有效信息只有32位”中的1位。
并且，在通过该PBCH扩展位进行PBCH扩展时，可以包括但不限于以下三种情形：
第一种、需要扩展PBCH，且需要发送PBCH扩展信息。
此种情形下，基站可以在需要扩展PBCH时，开启PBCH扩展位指示功能，该PBCH扩展位用于指示是否有PBCH扩展信息；然后在需要发送PBCH扩展信息时，可以将第一同步广播块中的PBCH扩展位设置为第一状态，该第一状态用于指示有PBCH扩展信息，将第一同步广播块发送至终端，以使终端根据第一状态确定有PBCH扩展信息；以及，生成PBCH扩展块，该PBCH扩展块中包括PBCH扩展信息，并在在设定扩展位置发送PBCH扩展块，以使终端在设定扩展位置接收PBCH扩展块，并从PBCH扩展块中获取PBCH扩展信息。
第二种，需要扩展PBCH，但暂时不需要发送PBCH扩展信息
此种情形下，基站可以在需要扩展PBCH时，开启PBCH扩展位指示功能，该PBCH扩展位用于指示是否有PBCH扩展信息；然后在不需要发送PBCH扩展信息时，可以将第二同步广播块中的PBCH扩展位设置为第二状态，该第二状态用于指示没有PBCH扩展信息，将第二同步广播块发送至终端，以使终端根据第二状态确定没有PBCH扩展信息。
第三种，不需要扩展PBCH
此种情形下，基站可以在不需要扩展PBCH时，关闭PBCH扩展位指示功能，将第三同步广播块中的PBCH扩展位设置为保留状态，该保留状态用于指示忽略PBCH扩展位，将第三同步广播块发送至终端，以使终端根据保留状态确定忽略PBCH扩展位。
因此，本公开通过设置PBCH扩展位来实现PBCH扩展，从而解决了不同终端的兼容性问题，提高了PBCH扩展的实用性。
下面以具体实施例来说明本公开实施例提供的技术方案。
图1是根据一示例性实施例示出的一种扩展PBCH的方法的流程图，该扩展PBCH的方法可以用于基站，PBCH的同步广播块中设置有PBCH扩展位。如图1所示，该扩展PBCH的方法包括以下步骤110-150：
在步骤110中，当需要扩展PBCH时，开启PBCH扩展位指示功能，该PBCH扩展位用于指示是否有PBCH扩展信息。
本公开实施例中，当需要扩展PBCH时，PBCH扩展位可以用于指示是否有PBCH扩展信息；当不需要扩展PBCH时，PBCH扩展位是一保留位，不用于指示是否有PBCH扩展信息。
在步骤120中，当需要发送PBCH扩展信息时，将第一同步广播块中的PBCH扩展位设置为第一状态，该第一状态用于指示有PBCH扩展信息。
本公开实施例中，第一状态可以是预定义的一种状态，并且利用该状态来指示PBCH扩展信息。
在一实施例中，第一状态为激活状态，该激活状态用于表征有PBCH扩展信息。
在一实施例中，第一状态为第一数值，该第一数值用于表征有PBCH扩展信息。比如：第一数值为1。
在步骤130中，将第一同步广播块发送至终端，以使终端根据第一状态确定有PBCH扩展信息。
在步骤140中，生成PBCH扩展块，该PBCH扩展块中包括PBCH扩展信息。该步骤与步骤130没有执行上的先后顺序，可以先执行步骤130，再执行步骤140；还可以先执行步骤140，再执行步骤130；也可以同时执行步骤130和步骤140。
本公开实施例中，PBCH扩展块可以是预定义的一种时频资源块，并且利用该时频资源块来承载PBCH扩展信息。
在一实施例中，同步广播块可以是承载同步信号和广播信息的时频资源块，PBCH扩展块可以是没有承载同步信号的时频资源块。
在步骤150中，在设定扩展位置发送PBCH扩展块，以使终端在设定扩展位置接收PBCH扩展块，并从PBCH扩展块中获取PBCH扩展信息。
本公开实施例中，设定扩展位置可以是预定义的一个扩展位置，并且，基站和终端都可以提前获知该设定扩展位置。
在一实施例中，设定扩展位置为第一同步广播块之后的指定时域位置。
比如：如图2A所示，同步广播块的发送周期为10ms，若同步广播块1为第一同步广播块，则该同步广播块1之后的PBCH扩展块1所在的时域位置可以为设定扩展位置。
在一实施例中，设定扩展位置为第一同步广播块之后的指定频域位置。
比如：如图2B所示，同步广播块的发送周期为5ms，若同步广播块1为第一同步广播块，则该同步广播块1之后的PBCH扩展块1所在的频域位置可以为设定扩展位置。
在一实施例应用场景中，如图2C所示，包括基站和终端。当需要扩展PBCH时，基站可以开启PBCH扩展位指示功能，该PBCH扩展位用于指示是否有PBCH扩展信息：(1)当基站需要发送PBCH扩展信息时，可以将第一同步广播块中的PBCH扩展位设置为第一状态，该第一状态用于指示有PBCH扩展信息，将第一同步广播块发送至终端，这样终端可以根据第一状态确定有PBCH扩展信息，生成PBCH扩展块，该PBCH扩展块中包括PBCH扩展信息，并在设定扩展位置发送PBCH扩展块，这样终端可以在设定扩展位置接收PBCH扩展块，并从PBCH扩展块中获取PBCH扩展信息；(2)当基站不需要发送PBCH扩展信息时，可以将第二同步广播块中的PBCH扩展位设置为第二状态，该第二状态用于指示没有PBCH扩展信息，将第二同步广播块发送至终端，这样终端可以根据第二状态确定没有PBCH扩展信息；(3)当基站不需要扩展PBCH时，可以关闭PBCH扩展位指示功能，将第三同步广播块中的PBCH扩展位设置为保留状态，该保留状态用于指示忽略PBCH扩展位，将第三同步广播块发送至终端，这样终端可以根据保留状态确定忽略PBCH扩展位。
由上述实施例可见，当需要扩展PBCH时，开启PBCH扩展位指示功能，该PBCH扩展位用于指示是否有PBCH扩展信息，当基站需要发送PBCH扩展信息时，可以将第一同步广播块中的PBCH扩展位设置为第一状态，该第一状态用于指示有 PBCH扩展信息，将第一同步广播块发送至终端，这样终端可以根据第一状态确定有PBCH扩展信息，生成PBCH扩展块，该PBCH扩展块中包括PBCH扩展信息，并在设定扩展位置发送PBCH扩展块，这样终端可以在设定扩展位置接收PBCH扩展块，并从PBCH扩展块中获取PBCH扩展信息，从而实现了扩展PBCH的功能，提高了PBCH扩展后的通信能力。

在一实施例中，第二状态为非激活状态，该非激活状态用于表征没有PBCH扩展信息。
在一实施例中，第二状态为第二数值，该第二数值用于表征没有PBCH扩展信息。比如：第二数值为0。
在步骤320中，将第二同步广播块发送至终端，以使终端根据第二状态确定没有PBCH扩展信息。
由上述实施例可见，当基站不需要发送PBCH扩展信息时，可以将第二同步广播块中的PBCH扩展位设置为第二状态，该第二状态用于指示没有PBCH扩展信息，将第二同步广播块发送至终端，这样终端可以根据第二状态确定没有PBCH扩展信息，从而丰富了扩展PBCH的实现形式，提高了扩展PBCH的实用性。
