在本公开实施例提供的信号接收、发送方法之中，UE可以接收基站发送的指示消息，其中，该指示消息包括PEI，该PEI用于指示该UE的参考信号的可用状态；以及，UE可以根据该参考信号的可用状态利用该参考信号进行同步。由此可知，本公开实施例中提供了一种新的方法来指示参考信号的可用状态，即：通过PEI来指示参考信号的可用状态。由此，基站可以根据多种方法来向UE指示参考信号的可用状态，灵活性较高。以及，通过向UE发送参考信号的可用状态，其中，当参考信号为可用状态时，则UE能够根据参考信号来实现与网络的时频域同步，从而可以缩短唤醒周期，降低功耗、节能省电。
下面参考附图对本公开提供的信号接收、发送方法、装置、用户设备、基站及存储介质进行详细描述。
图1为本公开实施例所提供的一种信号接收方法的流程示意图，应用于UE，如图1所示，该信号接收方法可以包括以下步骤：
步骤101、接收基站发送的指示消息。
需要说明的是，本公开实施例的信号接收方法可以应用在任意的UE中。UE可以是指向用户提供语音和/或数据连通性的设备。UE可以经RAN(Radio Access Network，无线接入网)与一个或多个核心网进行通信，UE可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remoteterminal)、接入终端(access terminal)、用户装置(user terminal)或用户代理(useragent)。或者，UE也可以是无人飞行器的设备。或者，UE也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线终端。或者，UE也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
以及，在本公开的一个实施例之中，指示消息可以包括PEI(Paging Early Indication，寻呼提前指示)，该PEI可以用于指示UE的参考信号的可用状态，以便UE可以根据参考信号的可用状态进行与网络的时频域的同步。其中，参考信号的可用状态可以包括参考信号可用或不可用，当参考信号可用时，UE才可以根据该参考信号进行与网络的时频域的同步。其中，在本公开的一个实施例之中，参考信号可以包括TRS和CSI-RS和SSS(Secondary Synchronization Signal，辅助同步信号)中的至少一种。
其中，UE接收基站发送的指示消息的方法可以包括但不限于以下方法：
在本公开的一个实施例之中，UE可以接收基站通过序列发送的指示消息。其中，在本公开的一个实施例之中，序列可以用于指示UE的参考信号的可用状态。
在本公开的另一个实施例之中，UE可以接收基站通过DCI(Downlink Control Information，下行控制信息)信令发送的指示消息。其中，在本公开的一个实施例之中，DCI信令可以包括paging DCI(寻呼下行控制信息，Paging Downlink Control Information)。以及，在本公开的一个实施例之中，DCI信令可以用于指示UE的参考信号的可用状态。
其中，需要说明的是，在本公开的一个实施例之中，UE可以在空闲状态/非激活状态时，接收基站发送的指示消息。
步骤102、该UE根据该参考信号的可用状态利用该参考信号进行同步。
综上所述，在本公开实施例提供的信号接收方法之中，UE可以接收基站发送的指示消息，其中，该指示消息包括PEI，该PEI用于指示该UE的参考信号的可用状态；以及，UE可以根据该参考信号的可用状态利用该参考信号进行同步。由此可知，本公开实施例中提供了一种方法来指示参考信号的可用状态，即：通过PEI来指示参考信号的可用状态。由此，基站可以根据多种方法来向UE指示参考信号的可用状态，灵活性较高。以及，通过向UE发送参考信号的可用状态，其中，当参考信号为可用状态时，则UE能够根据参考信号来实现与网络的时频域同步，从而可以缩短唤醒周期，降低功耗、节能省电。
图2a为本公开另一个实施例所提供的一种信号接收方法的流程示意图，应用于UE，如图2a所示，该信号接收方法可以包括以下步骤：
步骤201、接收基站通过序列发送的指示消息，该序列用于指示UE参考信号的可用状态。
需要说明的是，在本公开的一个实施例之中，该指示消息中可以包括有PEI。以及，在本公开的一个实施例之中，该序列可以用于承载PEI，以发送该PEI。
进一步地，在本公开的一个实施例之中，序列可以包括于序列集合中。其中，该序列集合可以包括第一部分序列和第二部分序列，该第一部分序列和该第二部分序列可以分别包括N组序列，N为正整数，每组序列可以包括n个比特，n为整数，n≥1。以及，在本公开的一个实施例之中，还可以对PDCCH(Physical Downlink Control Channel，物理下行控制信道)对应的UE进行分组以得到N组UE，其中，每组UE可以至少包括一个UE，以及，在本公开的一个实施例之中，对PDCCH对应的UE进行分组时，不同的UE组中可以包括相同数量的UE，例如，每一UE组均可以包括两个UE；在本公开的另一个实施例之中，不同的UE组中可以包括不同数量的UE，例如，一组UE可以包括两个UE，另外一组UE可以包括一个UE。并且，在本公开的一个实施例之中，N组UE中的每组UE可以分别对应一组序列，以便当基站利用序列发送PEI至UE时，UE组可以根据UE组与序列组的对应关系来确定该PEI 是否发送于自身。
以及，在本公开的一个实施例之中，第一部分序列中的N组序列可以分别用于指示对应的UE组的参考信号为可用状态。第二部分序列中的N组序列可以分别用于指示对应的UE组的参考信号为不可用状态。
由此，本公开的一个实施例之中，当UE确定PEI是发送于自身时，则可以进一步通过判定发送PEI的序列在序列集合中的所属部分(例如属于第一步部分序列或第二部分序列)，来判定该PEI指示的参考信号的可用状态为可用或不可用。
其中，需要说明的是，在本公开的一个实施例之中，第一部分序列可以为该序列集合中的一部分序列，第二部分序列可以为该序列集合中的另一部分序列。示例的，在本公开的一个实施例之中，第一部分序列可以为该序列集合中的前二分之一的序列，第二部分序列为该序列集合中的后二分之一的序列。
以及，还需要说明的是，在本公开的一个实施例之中，第一部分序列和第二部分序列中所包括的序列数应当是一致的，并且，第一部分序列和第二部分序列中对于序列的分组方式也应当是一致的。
进一步地，针对上述方法第一部分序列和第二部分序列的分组方法进行举例说明。
其中，图2b为本公开一个实施例所提供的序列组与UE组的对应关系图，如图2b所示。假设，对PDCCH对应的UE进行分组后得到4组UE，每组UE包括2个UE。则在本公开的一个实施例之中，可以将第一部分序列分为4组序列，同时，将第二部分序列也分为4组序列。其中，第一部分序列中的第1组序列可以对应于第1组UE，且可以用于指示第1组UE的参考信号可用，第二部分序列中的第1组序列可以对应于第1组UE，且可以用于指示第1组UE的参考信号不可用；第一部分序列中的第2组序列可以对应于第2组UE，且可以用于指示第2组UE的参考信号可用，第二部分序列中的第2组序列可以对应于第2组UE，且可以用于指示第2组UE的参考信号不可用。
步骤202、确定该用于发送指示消息的序列是否为与该UE对应的序列。
需要说明的是，在本公开的一个实施例之中，基站在向UE通过序列发送指示消息时，是将该指示消息发送至所有UE的，基于此，接收到指示消息的UE需要先判定该指示消息是否发送至自身。
其中，在本公开的一个实施例之中，UE判定该指示消息是否发送至自身的方法可以包括：确定该用于发送指示消息的序列是否为与该UE对应的序列。在本公开的一个实施例之中，当该序列为该UE对应的序列时，确定该指示消息为基站发送至该UE，则该UE继续执行步骤203；否则，确定该指示消息并非发送至该UE，则执行步骤204。
示例的，假设该用于发送指示消息的序列为上述第一部分序列中的第一组序列。则基站会通过第一部分序列中的第一组序列向所有UE发送指示消息。其中，当第一组UE接收到该指示消息时，由于第一部分序列中的第一组序列与第一组UE对应，则第一组UE可以确定该指示消息是发送至自身的；当第二组UE接收到该指示消息时，由于第一部分序列中的第一组序列未与第二组UE对应，则第二组UE可以确定该指示消息不是发送至自身的。
步骤203、确定该用于发送指示消息的序列在序列集合中的所属部分，以判定指示消息所指示的参考信号的可用状态。
其中，在本公开的一个实施例之中，当该用于发送指示消息的序列属于序列集合的第一部分序列时，确定所述UE的参考信号为可用状态。当该用于发送指示消息的序列序列属于序列集合的第二部分序列时，确定UE的参考信号为不可用状态。
示例的，针对第一组UE而言，当该用于发送指示消息的序列为第一部分序列中的第一组序列时，则可以确定第一组UE的参考信号可用；当该用于发送指示消息的序列为第二部分序列中的第一组序列时，则可以确定第一组UE的参考信号不可用。
进一步地，需要说明的是，本公开的一个实施例之中，通过对UE进行分组，并使得每组UE有对应的序列组。由此，当后续要唤醒某一个UE时，仅需唤醒该UE所属UE组中的全部UE即可，而无需唤醒所有UE，从而可以节省功耗，降低成本。
步骤204、不予回应。
步骤205、该UE根据该参考信号的可用状态利用该参考信号进行同步。
