Description

寻呼同步方法及装置 技术领域
本公开涉及通信领域，尤其涉及一种寻呼同步方法及装置。
背景技术
在新一代通信技术中，尤其在非授权频谱设计上，需要考虑多种与之相关的法规。比如：LBT(Listen Before Talk，先听后发)机制，且该LBT机制可以指的是发射信号之前必须要先探测信道能量，如果判断有干扰则必须等待。并且，在非授权频谱小区独立组网的场景下，终端的寻呼同步主要依赖于基站发送的SSB(Synchronous Signal Block，同步信号块)。当基站能够发送SSB时，终端可以根据基站发送的SSB进行同步后，再去接收寻呼，这样接收成功率比较大。但是，若基站不能发送SSB了，则终端在寻呼接收过程中，会在没有同步的情形下接收寻呼，其失败概率较大，从而造成了寻呼接收性能下降。
发明内容
为克服相关技术中存在的问题，本公开实施例提供一种寻呼同步方法及装置。

可选地，所述预先指定位置位于用于发送所述待发送至所述终端的PO的第二发送位置之前、或位于所述第二发送位置的指定区域。
根据本公开实施例的第二方面，提供一种寻呼同步方法，所述方法用于终端，所述方法包括：
当确定没有接收到用于终端进行同步的SSB时，接收所述基站为待发送至所述终端的PO配置的用于寻呼同步的参考信号；
根据所述参考信号进行寻呼同步。
可选地，所述方法还包括：
确定SSB发送周期内用于接收SSB的一个或多个第一接收位置；
若在各个所述第一接收位置均没有接收到SSB时，则确定没有接收到用于终端进行同步的SSB。
可选地，所述方法还包括：

接收所述基站发送的寻呼同步信令，所述寻呼同步信令中包括用于表征所述预先指定位置的位置信息；
根据所述寻呼同步信令中包括的所述位置信息确定所述预先指定位置。
可选地，所述预先指定位置位于用于接收所述待发送至所述终端的PO的第二接收位置之前、或位于所述第二接收位置的指定区域。
根据本公开实施例的第三方面，提供一种非临时计算机可读存储介质，所述存储介质上存储有计算机程序，所述计算机程序用于执行上述第一方面的寻呼同步方法。

应当理解的是，以上的一般描述和后文的细节描述仅是示例性和解释性的，并不能限制本公开。

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”。
图1是根据一示例性实施例示出的一种寻呼同步方法的流程图，图2是根据一示例性实施例示出的一种寻呼同步方法的应用场景图；该寻呼同步方法可以用于基站。如图1所示，该寻呼同步方法包括以下步骤110-130：
在步骤110中，当确定不能发送用于终端进行同步的SSB时，为待发送至该终端的PO(Paging Occasion，寻呼时机)配置用于寻呼同步的参考信号。
本公开实施例中，基站在寻呼发送过程中，一般先发送用于终端进行同步的SSB，再发送PO(即在PO里发送寻呼消息)。但是，当确定不能发送用于终端进行同步的SSB时，还可以为待发送的PO配置用于寻呼同步的参考信号，并将用于寻呼同步的参考信号发送至终端，这样，终端在没有接收到用于终端进行同步的SSB时，还可以根据用于寻呼同步的参考信号进行寻呼同步后，再去接收PO，从而保证了终端具有较高的寻呼接收性能，还提高了寻呼同步的效率。
其中，基站能发送用于终端进行同步的SSB的原因为：由于LBT机制的存在，所以基站在发送SSB之前，必须要先探测信道能量，如果判断有干扰则需要放弃发送SSB，这样该基站覆盖范围内的所有终端都不能接收到用于终端进行同步的SSB。也 接收说，基站发送SSB之前，若检测到信道没有被占用，则就能发送该SSB；若检测到信道已被占用，则就不能发送该SSB。
在确定不能发送用于终端进行同步的SSB后，为了不降低终端的寻呼接收性能，基站还需要为终端提供用于寻呼同步的参考信号。
在一实施例中，上述步骤110中的参考信号可以为一个伪随机序列。比如：基站根据一定规则生成的一个伪随机序列。
在步骤120中，将用于寻呼同步的参考信号发送至终端，以使该终端根据用于寻呼同步的参考信号进行寻呼同步。
在一实例性场景中，如图2所示，包括基站、作为UE的智能手机。基站在确定不能发送用于终端进行同步的SSB时，会为待发送至该终端的PO配置用于寻呼同步的参考信号，将用于寻呼同步的参考信号发送至终端，这样终端在确定没有接收到用于终端进行同步的SSB时，可以接收基站配置的参考信号，并可以根据该参考信号进行寻呼同步。
由上述实施例可见，在确定不能发送用于终端进行同步的SSB时，可以为待发送至终端的PO配置用于寻呼同步的参考信号，并将用于寻呼同步的参考信号发送至终端，这样，终端在唤醒后没有接收到用于终端进行同步的SSB时，还可以根据用于寻呼同步的参考信号进行寻呼同步，从而保证了终端具有较高的寻呼接收性能，还提高了寻呼同步的效率。
图3A是根据一示例性实施例示出的另一种寻呼指示方法的流程图，该寻呼指示方法可以用于基站，并建立在图1所示方法的基础上，如图3A所示，该寻呼同步方法还可以包括以下步骤310-320：
在步骤310中，确定SSB发送周期内用于发送SSB的一个或多个第一发送位置。
本公开实施例中，SSB发送周期内可以发送SSB的位置可能有一个，如图3B所示的第一发送位置；也可以能有多个，如图3C所示的各个第一发送位置，这都是基站根据实际情形配置的。其中，SSB发送周期的时间长度可以为20ms。
在一实施例中，上述步骤310中在确定SSB发送周期内用于发送SSB的一个或多个第一发送位置时，可以包括但不限于以下确定方式：
(1-1)若SSB发送周期内配置了一个SSB位置，则该SSB位置为第一发送位置，如图3B所示的第一发送位置。
本公开实施例中，该SSB位置可以是基站配置的唯一发送位置，若在这唯一发送位置不能发送SSB，该基站就需要为终端配置用于寻呼同步的参考信号。
另外，一个SSB周期的时间长度可以为20ms。
(1-2)若SSB发送周期内配置了多个SSB位置，则各个SSB位置均为第一发送位置，如图3C所示的各个第一发送位置。
本公开实施例中，这多个SSB位置中可以有一个基站配置的常用发送位置，其余的都是备用发送位置，只有在所有的发送位置均不能发送SSB，该基站才需要为终端配置用于寻呼同步的参考信号。
在步骤320中，若确定各个第一发送位置均不满足SSB发送条件时，则确定不能发送用于终端进行同步的SSB。
本公开实施例中，不管基站配置了多少第一发送位置，只有所有第一发送位置都不能发送SSB时，基站才最终确定不能发送用于寻呼同步的SSB，此时才需要为终端配置用于寻呼同步的参考信号。
在一实施例中，上述步骤320中SSB发送条件可以包括在发送SSB之前，检测到信道没有被占用。
在一实施例中，执行步骤310之后，如图3A所示，还可以包括以下步骤330：
在步骤330中，若确定至少一个第一发送位置满足SSB发送条件时，则在满足SSB发送条件的第一发送位置上发送用于终端进行同步的SSB。
本公开实施例中，若只有一个第一发送位置满足SSB发送条件，可以在该第一发送位置上发送用于终端进行同步的SSB。
若有多个第一发送位置满足SSB发送条件，可以从这多个第一发送位置中选取一个第一发送位置上发送用于终端进行同步的SSB。
由上述实施例可见，在确定SSB发送周期内用于发送SSB的一个或多个第一发送位置后，只有各个第一发送位置均不满足SSB发送条件时，才确定不能发送用于终端进行同步的SSB，并为待发送的PO配置用于寻呼同步的参考信号，从而提高了 参考信号配置的准确性。
图4A是根据一示例性实施例示出的另一种寻呼指示方法的流程图，该寻呼指示方法可以用于基站，并建立在图1所示方法的基础上，在执行步骤120时，如图4A所示，可以包括以下步骤410-420：
在步骤410中，确定SSB发送周期内用于发送用于寻呼同步的参考信号的预先指定位置。
本公开实施例中，预先指定位置可以是基站提前配置的，并与终端事先约定好的；也可以是基站动态配置的，并通过寻呼同步信令将该预先指定位置通知给终端的，可详见图5所示实施例。
在一实施例中，上述步骤410中的预先指定位置可能位于用于发送所述待发送至终端的PO的第二发送位置之前，如图4B所示的预先指定位置；也可能位于第二发送位置的指定区域，比如：PO的前几个符号为参考信号，如图4C所示的预先指定位置。
在步骤420中，在预先指定位置将用于寻呼同步的参考信号发送至终端，以使该终端在预先指定位置接收用于寻呼同步的参考信号。
由上述实施例可见，可以先确定用于发送用于寻呼同步的参考信号的预先指定位置，并在预先指定位置将用于寻呼同步的参考信号发送至终端，这样该终端可以在预先指定位置接收用于寻呼同步的参考信号，从而提高了参考信号接收的准确性。
图5是根据一示例性实施例示出的另一种寻呼指示方法的流程图，该寻呼指示方法可以用于基站，并建立在图4A所示方法的基础上，该寻呼指示方法还可以包括以下步骤510-520：
在步骤510中，生成寻呼同步信令，该寻呼同步信令中包括用于表征基站配置的预先指定位置的位置信息。
在步骤520中，将包括所述位置信息的寻呼同步信令发送至终端，以使所述终端根据寻呼同步信令中包括的所述位置信息确定预先指定位置。
由上述实施例可见，可以生成寻呼同步信令，该寻呼同步信令包括基站配置的预先指定位置，并将寻呼同步信令发送至终端，这样终端可以根据寻呼同步信令确定预先指定位置，从而实现了预先指定位置的动态配置，提高了寻呼同步的灵活性。
图6是根据一示例性实施例示出的一种寻呼同步方法的流程图，该寻呼同步方法可以用于终端，如图6所示，该寻呼同步方法可以包括以下步骤610-620：
在步骤610中，当确定没有接收到用于终端进行同步的SSB时，接收基站为待发送至该终端的PO配置的用于寻呼同步的参考信号。
本公开实施例中，在寻呼接收过程中，一般先接收用于终端进行同步的SSB并根据该SSB同步后，再去接收PO(即在PO里接收寻呼消息)。但是，当确定没有接收到用于终端进行同步的SSB时，还可以接收基站为待发送的PO配置的用于寻呼同步的参考信号，并根据用于寻呼同步的参考信号进行寻呼同步，这样可以避免由于没有接收到SSB进行同步而造成的寻呼接收性能下降，从而保证了终端具有较高的寻呼接收性能，还提高了寻呼同步的效率。
其中，终端没有接收到用于终端进行同步的SSB的原因为：由于LBT机制的存在，所以基站在发送SSB之前，必须要先探测信道能量，如果判断有干扰则需要放弃发送SSB，所以该基站覆盖范围内的终端也可能接收不到用于终端进行同步的SSB。
在确定没有接收到用于终端进行同步的SSB后，为了不降低寻呼接收性能，终端还需要接收基站配置的用于寻呼同步的参考信号。
在一实施例中，上述步骤610中的参考信号可以为一个伪随机序列。比如：基站根据一定规则生成的一个伪随机序列。
在步骤620中，根据用于寻呼同步的参考信号进行寻呼同步。
由上述实施例可见，在确定没有接收到用于终端进行同步的SSB时，可以接收基站为待发送至终端的PO配置的用于寻呼同步的参考信号，并根据用于寻呼同步的参考信号进行寻呼同步，从而保证了终端具有较高的寻呼接收性能，还提高了寻呼同步的效率。
图7A是根据一示例性实施例示出的另一种寻呼指示方法的流程图，该寻呼指示方法可以用于终端，并建立在图6所示方法的基础上，如图7A所示，该寻呼同步方法可以包括以下步骤710-720：
在步骤710中，确定SSB发送周期内用于接收SSB的一个或多个第一接收位置。
本公开实施例中，可以接收SSB的位置可能有一个，如图7B所示的第一接收 位置；也可以能有多个，如图7C所示的各个第一接收位置，这都是终端根据基站的配置确定的。
在一实施例中，上述步骤710中在确定SSB发送周期内用于接收SSB的一个或多个第一接收位置时，可以包括但不限于以下确定方式：
(2-1)若SSB发送周期内配置了一个SSB位置，则该SSB位置为第一接收位置，如图7B所示的第一接收位置。
本公开实施例中，该SSB位置可以是终端根据基站的配置确定的唯一接收位置，若在这唯一接收位置不能接收到SSB，该终端就需要在预先指定位置接收基站配置的用于寻呼同步的参考信号。
(2-2)若SSB发送周期内配置了多个SSB位置，则各个SSB位置均为第一发送位置，如图7C所示的各个第一接收位置。
本公开实施例中，这多个SSB位置中可以有一个是终端根据基站的配置确定的常用接收位置，其余的都是备用接收位置，只有在所有的接收位置均不能接收到SSB，该终端才需要在预先指定位置接收基站配置的用于寻呼同步的参考信号。
在步骤720中，若在各个第一接收位置均没有接收到SSB时，则确定没有接收到用于终端进行同步的SSB。
本公开实施例中，不管基站配置了多少第一发送位置，只有所有第一接收位置都没有接收到用于终端进行同步的SSB时，终端才最终确定没有接收到用于终端进行同步的SSB，此时才需要接收基站配置的用于寻呼同步的参考信号。
在一实施例中，执行步骤710之后，如图7A所示，还可以包括以下步骤730：
在步骤730中，若在至少一个第一接收位置接收到SSB时，则根据接收到的SSB进行寻呼同步。
本公开实施例中，不管在哪个第一接收位置接收到SSB，都可以根据接收到的SSB进行寻呼同步。
由上述实施例可见，在确定用于接收SSB的一个或多个第一接收位置后，只有各个第一接收位置均没有接收到SSB时，才确定没有接收到用于终端进行同步的SSB，并接收基站为待发送的PO配置的用于寻呼同步的参考信号，以及根据用于寻呼同步 的参考信号进行寻呼同步，从而提高了参考信号接收的准确性。
