本公开实施例涉及通信技术领域，特别是指一种寻呼消息的发送方法、接收方法、基站及终端。
背景技术
5G高频段需要通过大规模天线来对抗路损的问题，模拟数字混合波束赋形架构是5G高频大规模天线最有可能采用的架构(从成本、复杂度、性能等方面综合考虑)。然而，由于模拟波束赋形只能在时域改变波束方向，是一个全带宽的行为，因此模拟数字混合波束赋形会对5G系统设计产生较大的影响，其中的一个影响就是寻呼(paging)的方式。
在5G高频段系统中，基站的波束比较窄，而且模拟波束只能在时间上进行调整。如果依然采用与LTE中类似的方法发送寻呼消息，由于基站不知道被寻呼的用户所处的位置，只能采用波束扫描的方式在所有可能的波束上都发送寻呼消息。这意味着，即使只是为了寻呼某一个UE，基站也需要在多个子帧上依次采用不同的波束发送相同的寻呼消息，这会使得一次寻呼(一个PO)需要占用多个子帧，导致UE需要监视的时间变长，耗电增加。而且，由于不同的UE使用不同的PO，基站需要在不同的时间上寻呼不同的用户，每寻呼一个用户都需要采用波束扫描的方式耗费多个子帧来发送寻呼消息。另外，当某些子帧需要通过波束扫描的方式发送寻呼消息的时候，这些子帧可以使用的模拟波束就受到了限制，从而也降低了基站调度的灵活性。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
第一实施例
在LTE系统中，寻呼消息的作用包括向处于RRC_IDLE(无线链路控制-空闲)态的用户设备UE发送呼叫请求、通知处于RRC_IDLE和RRC_CONNECTED(无线链路控制-连接)态的UE系统信息发生了变化等。
PCH(Paging Channel，寻呼信道)用于传输来自PCCH(寻呼控制信道)逻辑信道的寻呼消息，PCH传输信道直接映射到PDSCH(物理下行共享信道)物理信道，与DL-SCH(下行共享信道)数据共同参与下行调度。
为了接收来自eNodeB(节点B)的寻呼消息，处于RRC_IDLE态的UE会监听使用P-RNTI(寻呼标识)加扰的PDCCH。寻呼支持非连续接收(DRX)，使得处于RRC_IDLE态的UE只在预先定义好的时间段内“醒来”以接收寻呼消息，而在其它时间可以保持“休眠”状态，这样就能够降低功耗，提升UE的电池使用时间。
寻呼消息所占的频域资源是PDCCH(物理下行控制信道)指定的。而在时域上，UE只会在其寻呼周期内的某个特定帧(称为PF)的特定子帧(称为PO)去尝试接收寻呼消息。
当使用了DRX(非连续接收)，UE在每个DRX cycle(非连续接收周期)上只需要检测1个PO。也就是说，对应每个UE，在每个寻呼周期内只有1个子帧可用于发送寻呼消息。
PF(寻呼帧)是一个无线帧，该帧可能包含一个或多个PO。
PF是满足如下公式的系统帧：SFN mod T＝(T div N)*(UE_ID mod N)。其中，(T div N)相当于把一个DRX cycle等分成N份后，每一份包含的系统帧，(UE_ID mod N)相当于取N等份里的第“UE_ID mod N”(取值范围为0～N-1)份，而PF为其中的第一个系统帧，其中UE_ID为IMSI mod 1024。一个PF中根据配置可能包括1个或多个PO，UE具体在哪个PO上检测也取决于UE_ID。
如果UE在PO上检测到使用P-RNTI加扰的PDCCH，UE会去读取PDSCH，其中包含了被寻呼的UE的标志ue-Identity。
如果UE发现自己的UE标志与某个ue-Identity一致，就会把ue-Identity和相关信息发往上层继续处理。
如果UE没有找到一个与其UE标志一致的ue-Identity，UE会丢弃接收到的寻呼消息，并进入休眠。
在LTE系统中，从某个UE来看，只需要监视自己的PO就可以了(具体的PO位置与IMSI有关)。这样就能够降低功耗，提升UE的电池使用时间；对于基站来说，在所有UE的PO上都有可能要发寻呼消息。
在5G高频段系统中，基站的波束比较窄，而且模拟波束只能在时间上调整。如果依然采用与LTE中类似的方法发送寻呼消息，由于基站不知道被寻呼的用户所处的位置，只能采用波束扫描的方式在所有可能的波束上都发送寻呼消息。这意味着，即使只是为了寻呼某一个UE，基站也需要在多个子帧上依次采用不同的波束发送相同的寻呼消息，这会使得一次寻呼(一个PO)需要占用多个子帧，导致UE需要监视的时间变长，耗电增加。而且由于不同的UE使用不同的PO，基站需要在不同的时间上寻呼不同的用户，每寻呼一个用户都需要采用波束扫描的方式耗费多个子帧来发送寻呼消息。另外，当某些子帧需要通过波束扫描的方式发送寻呼消息的时候，这些子帧可以使用的模拟波束就受到了限制，从而也降低了基站调度的灵活性。
如图1所示，本公开的实施例提供了一种寻呼消息的发送方法，包括：
步骤11，发送至少一个第一物理下行控制信道PDCCH消息，所述第一PDCCH消息携带有指示发送寻呼消息时所采用的资源的第一指示信息；可选 的，在发送寻呼消息的子帧中发送至少一个第一物理下行控制信道PDCCH消息，所述第一PDCCH消息携带有指示发送寻呼消息时所采用的资源的第一指示信息；以及
步骤12，利用所述资源，向被配置为具有相同标识的至少一个终端发送至少一个寻呼消息；可选的，在所述子帧中，根据所述第一指示信息，向被配置为具有相同标识的至少一个终端发送至少一个寻呼消息。
本实施例提出的寻呼消息的发送方法，适用于5G系统，系统中在确定某个UE的寻呼周期中的被寻呼时刻(如Paging Frame(寻呼帧)和Paging Occasion(寻呼时机))时使用的UE_ID(终端标识)可以由网络侧配置(例如通过系统消息等方式)，网络侧可以通过配置，使得两个或多个用户使用相同的UE_ID，从而使得这些相同UE_ID的终端可以在相同的时刻(如寻呼帧或者寻呼时刻)来监听寻呼消息，这样从基站的角度来看，可以分配较少的时间资源用于潜在的寻呼消息发送，降低对基站调度灵活性的限制。
该实施例中，步骤11中，具体可以包括：在发送寻呼消息的子帧中，发送至少一个由寻呼标识P-RNTI加扰的第一PDCCH消息。
比如，当某个时间调度单元(如一个子帧，或一个时隙，或一个微时隙)用于寻呼的话，可以采用如下方法，假设将该时刻的子帧划分为PDCCH区域和PDSCH区域：
在PDCCH区域，基站发送N1个由P-RNTI加扰的PDCCH，每个PDCCH对应于基站的波束(可以对应1个或多个波束的覆盖范围)，该PDCCH指示了1个或多个寻呼消息(每个寻呼消息由某个基站波束发送)在PDSCH区域占用的资源；其中，N1为正整数。
并进一步的，上述实施例中，发送寻呼消息时所采用的资源包括：发送寻呼消息所采用的波束以及寻呼消息占用的OFDM(正交频分复用)符号资源；其中，寻呼消息占用的符号资源具体可以是该寻呼消息在PDSCH(物理下行共享信道)占用的符号资源，寻呼消息在PDSCH占用的资源可以包括：寻呼消息在PDSCH占用的符号资源以及带宽资源。
相应的，上述实施例中的步骤12可以包括：通过所述第一指示信息指示的波束，在所述第一指示信息指示的寻呼消息占用的OFDM资源上，向被配 置为具有相同标识的至少一个终端发送至少一个寻呼消息。具体的，可以是在发送寻呼消息的子帧中，通过所述第一指示信息指示的波束，在所述第一指示信息指示的寻呼消息在PDSCH占用的OFDM资源上，向被配置为具有相同标识的至少一个终端发送至少一个寻呼消息。
比如，在PDSCH区域，基站发送N2个寻呼消息，每个寻呼消息由某个波束发送；其中，N2为正整数。
可选的，本公开的上述实施例中，一个寻呼消息通过一个波束发送。不同波束对应的寻呼消息通过时分复用或者频分利用的方式占用OFDM符号资源。具体的，不同波束对应的寻呼消息通过时分复用或者频分利用的方式占用PDSCH。一个寻呼消息占用PDSCH的至少一个OFDM符号资源或者一个寻呼消息在PDSCH占用部分带宽或者全部带宽。不同的寻呼消息在PDSCH占用相同的带宽或者不同的寻呼消息在PDSCH占用不同的带宽。
也就是说，寻呼消息占用的资源的分配方式并非占满了PDSCH区域的所有符号，一个寻呼消息可以只占用PDSCH区域的1个或多个符号，不同波束对应的多个寻呼消息通过TDM(时分复用)的方式占用PDSCH区域。一个寻呼消息可以占满整个带宽或只占用部分带宽。
另外，PDCCH的个数N1和寻呼消息的个数N2可以是一对一或一对多的关系，即一个PDCCH可以指示一个或多个寻呼消息的资源占用、使用的波束等信息。
本公开的该实施例中，第一PDCCH消息也是可以通过基站的波束发送，且该波束也可以是该第一PDCCH消息指定的波束，该波束可以是和发送寻呼消息时采用的波束是相同的波束。比如，PDCCH1指定发送寻呼消息1的波束1，该PDCCH1也可以采用波束1发送。PDCCH2指定发送寻呼消息2的波束2，该PDCCH2也可以采用波束2发送。当然，PDCCH1如果指定发送寻呼消息1所采用的波束1和寻呼消息2所采用的波束2，该PDCCH1即可以采用波束1发送，也可以采用波束2发送。当然，本公开的其它实施例中，PDCCH的发送还可能有其它方式，并不限于上述列举的方式。
下面结合具体的应用实例说明上述实施例所述方法的实现过程：
如图2所示，假设基站需要在3个波束上扫描才能覆盖整个小区，基站 在该时刻需要给两个UE发送寻呼消息，该两个UE可以具有相同的UE ID，当然该两个UE也可以具有不同的UE ID。
在PDCCH区域，基站发送3个由P-RNTI加扰的PDCCH(PDCCH1，PDCCH2，PDCCH3)，分别指示了3个寻呼消息占用的资源、使用的波束等信息。具体的，PDCCH1指示寻呼消息1占用的符号资源、使用的波束等信息。PDCCH2指示寻呼消息2占用的符号资源、使用的波束等信息。PDCCH3指示寻呼消息3占用的符号资源、使用的波束等信息。
在PDSCH区域，基站发送3个寻呼消息，分别对应不同的波束。每个寻呼消息占用1个符号，并占用PDSCH的全部带宽。
如图3所示，假设基站需要在3个波束上扫描才能覆盖整个小区，基站在该时刻需要给两个UE发送寻呼消息，该两个UE可以具有相同的UE ID，当然该两个UE也可以具有不同的UE ID。
在PDCCH区域，基站发送2个由P-RNTI加扰的PDCCH，其中一个PDCCH指示了2个寻呼消息(寻呼消息1和寻呼消息2)占用的资源、使用的波束等信息。另一个PDCCH指示了1个寻呼消息占用的资源、使用的波束等信息。
在PDSCH区域，基站发送3个寻呼消息，分别对应不同的波束。每个寻呼消息占用1个符号，并占用PDSCH的全部带宽。
如图4所示，假设基站需要在3个波束上扫描才能覆盖整个小区，基站在该时刻需要给两个UE发送寻呼消息，该两个UE可以具有相同的UE ID。
在PDCCH区域，基站发送3个由P-RNTI加扰的PDCCH，分别指示了3个寻呼消息占用的资源、使用的波束等信息。
在PDSCH区域，基站发送3个寻呼消息，分别对应不同的波束。每个寻呼消息占用1个符号，但是3个寻呼消息可以占用PDSCH的不同的带宽。
第二实施例
如图5所示，本公开的实施例还提供一种寻呼消息的发送方法，包括：
步骤51，发送至少一个第一物理下行控制信道PDCCH消息以及第二物理下行控制信道PDCCH消息，所述第一PDCCH消息携带有指示发送寻呼消息时所采用的资源的第一指示信息；所述第二PDCCH消息携带有指示发送 用户数据的PDSCH的符号资源以及用户数据在PDSCH占用的带宽的第二指示信息；以及
步骤52，根据所述第一指示信息，向被配置为具有相同标识的至少一个终端发送至少一个寻呼消息，以及根据所述第二指示信息，向被配置为具有相同标识的至少一个所述终端发送所述用户数据。
本公开的该实施例中，未被寻呼消息占用的PDSCH区域，可以用于发送正常用户数据的PDSCH，但需要在相应PDCCH中指示该PDSCH占用的时频资源，相对于普通子帧的PDSCH需要指示该PDSCH占用的符号资源并非PDSCH区域的全部符号资源。
如图6所示，未被寻呼消息占用的PDSCH区域，可以用于发送正常用户数据的PDSCH，但需要在相应PDCCH4中指示该PDSCH占用的时频资源，相对于普通子帧的PDSCH，需要指示该PDSCH占用的符号资源并非PDSCH区域的全部符号资源。
本公开的上述实施例所述的寻呼消息的发送方法，适用于5G高频系统中，能够提升寻呼的效率，降低UE的耗电，提升系统的资源利用率。
第三实施例
如图7所示，本公开的实施例还提供一种寻呼消息的接收方法，包括：
步骤71，接收至少一个第一物理下行控制信道PDCCH消息，所述第一PDCCH消息携带有指示接收寻呼消息时所采用的资源的第一指示信息；以及
步骤72，利用所述资源，接收基站发送的至少一个寻呼消息。
该实施例中，具有相同标识的至少一个终端在接收寻呼消息的子帧中，接收至少一个第一物理下行控制信道PDCCH消息，并在所述子帧中，根据所述第一指示信息，接收基站发送的至少一个寻呼消息。从而使得这些相同UE_ID的终端可以在相同的时刻(如寻呼帧或者寻呼时刻)来监听寻呼消息，这样从基站的角度来看，可以分配较少的时间资源用于潜在的寻呼消息发送，降低对基站调度灵活性的限制。
该实施例中，接收寻呼消息时所采用的资源包括：接收寻呼消息所采用的波束以及寻呼消息占用的正交频分复用OFDM符号资源。
步骤72具体可以包括：通过所述第一指示信息指示的波束，在所述第一 指示信息指示的寻呼消息占用的OFDM符号资源上，接收基站发送的至少一个寻呼消息。

本公开的该实施例中，接收第一PDCCH消息的波束，可以是和接收寻呼消息时采用的波束是相同的波束。比如，接收寻呼消息1的波束为波束1，也可以采用波束1接收PDCCH1。接收寻呼消息2的波束为波束2，该PDCCH2也可以采用波束2接收。当然，PDCCH1如果指定发送寻呼消息1所采用的波束1和寻呼消息2所采用的波束2，可以采用波束1接收PDCCH1，也可以采用波束2接收。当然，本公开的其它实施例中，PDCCH的接收还可能有其它方式，并不限于上述列举的方式。
进一步的，该第三实施例所述的寻呼消息的接收方法，还可以包括：

根据所述第二指示信息，接收基站发送的所述用户数据。
也就是说，未被寻呼消息占用的PDSCH区域，可以用于接收正常用户数据的PDSCH，但需要在相应PDCCH4中指示该PDSCH占用的时频资源，相对于普通子帧的PDSCH，需要指示该PDSCH占用的符号资源并非PDSCH区域的全部符号资源。

该实施例中，第一接收模块91和第二接收模块92在具体实现时，可以由终端的接收来实现，且该终端还可以具有控制接收机接收PDCCH消息、寻呼消息以及用户数据的处理器、控制器和/或存储器等。
需要说明的是，该终端的实施例是与上述第三实施例所述的方法对应的装置，上述第三实施例中所有实现实例均适用于该终端的实施例中，也能达到相同或相似的技术效果。
本公开的上述实施例通过基站配置多个UE使用相同的UE ID，具有相同UE ID的UE可以在相同的子帧监听寻呼消息，通过一个PDCCH可以指示至少一个寻呼消息(一个寻呼消息由基站在一个波束发送)在PDSCH占用的资源信息，一个寻呼消息可以只占用PDSCH的一个或多个符号，不同波束对应的寻呼消息通过时分的方式占用PDSCH，一个寻呼消息可以占用整个带宽或只占用部分带宽。
由于多个UE使用相同的UE ID，在相同的子帧监听寻呼消息，基站不必对于一个UE都在多个子帧上依次通过多个波束发送相同的寻呼消息，节省了子帧资源。
