Description

寻呼控制信息的指示、接收方法及装置、存储介质、基站、终端
本申请要求于2018年04月03日提交中国专利局、申请号为201810290992.4、发明名称为“寻呼控制信息的指示、接收方法及装置、存储介质、基站、终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域，具体地涉及一种寻呼控制信息的指示、接收方法及装置、存储介质、基站、终端。
背景技术
在长期演进(Long Term Evolution，简称LTE)技术中，网络广播寻呼(Paging)消息。寻呼消息的作用包括：1)网络向处于无线资源控制_空闲(Radio Resource Control_Idle，简称RRC_IDLE)态的用户设备(User Equipment，简称UE)发送呼叫请求；2)网络通知处于RRC_IDLE态和RRC_连接(也即RRC_CONNECTED)态的UE，系统信息发生变化；3)网络通知UE开始接收地震和海啸预警系统(Earthquake and Tsunami Warning System，简称ETWS)主通知指示(Primary notification)和/或ETWS辅通知指示(Secondarynotification)；4)网络通知UE开始接收商业移动警报服务(Commercial Mobile Alert Service，简称CMAS)通知指示。
在第五代移动通信(The Fifth-Generation mobile communications，简称5G)新无线(New Radio，简称NR)系统中，仍然广播寻呼消息。当系统信息发生改变时，仍然可以通过寻呼消息指示系统信息是否发生改变。由于不需要通知UE哪些系统信息发生改变，因此寻呼消息中的系统信息更新指示域所占比特数比较少。而且，为了降低网络的信令开销以及UE功耗，第三代合作伙伴项目(the 3rd Generation  Partnership Project，简称3GPP)工作组确定NR系统中连接态UE不需要解码PDSCH，当寻呼消息承载系统信息发生改变或通知接收ETWS通知指示或CMAS通知指示时，可直接通过物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)承载。为此，用于承载寻呼控制信息的PDCCH下行控制信息(Downlink Control Information，简称DCI)增加1比特短消息指示(Short Message Indicator)域，以指示系统信息等消息是否更新。该短消息指示域还可以指示是否承载被寻呼UE的寻呼消息调度信息。
此外，5G NR系统提出部分载波带宽(Band Width Part，简称BWP)概念以支持不同带宽能力的UE。为了节省UE功耗，网络可以根据UE的带宽接收能力为其配置多个不同带宽长度或不同数理(Numerology)参数的BWP，且每个BWP均在UE的最大接收带宽范围内。网络和/或UE可以根据UE的业务需求以及负载情况自适应调整BWP，以节省UE功耗，提高传输速率，提升用户体验。
在网络基站(例如gNB)给UE配置BWP后，为了保证UE能及时接收寻呼消息，需在每个BWP上都配置监听寻呼消息的公共搜索空间。连接态UE需要在该UE的激活BWP的任意一个寻呼时机(Paging Occasion，简称PO)监听寻呼公共搜索空间对应的控制资源集，以解码寻呼控制信息；空闲态或非激活态UE需要在初始激活的BWP，且与该空闲态或非激活态UE对应的寻呼时机上监听寻呼公共搜索空间对应的控制资源集，以解码寻呼控制信息。
对连接态UE而言，由于连接态UE只关心是否发生系统信息更新，是否需要接收ETWS通知指示、CMAS通知指示等信息，因而携带系统信息更新等信息的寻呼控制信息不需要区分UE。如果在gNB配置给UE的激活BWP上的寻呼公共搜索空间对应的控制资源集与初始BWP上的寻呼公共搜索空间对应的控制资源集相同，且同时出现被寻呼UE以及系统信息更新等消息，那么按照现有技术，gNB可以只发送一次寻呼消息。此时，DCI需要承载寻呼消息调度信息指 示；之后通过物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)承载被寻呼UE的寻呼消息和系统信息更新等消息，由于连接态UE不需要解码PDSCH，因而连接态UE无法获得系统信息更新等消息；基站也可以发送2次寻呼消息，其中一次只承载系统信息更新等消息，通过PDCCH承载，另一次只承载被寻呼UE列表的寻呼消息调度信息指示，不仅浪费下行资源，还会导致连接态UE因先收到承载调度寻呼消息的资源分配的下行控制信息，而忽略接收携带系统信息更新等消息的下行控制信息。

具体实施方式
本领域技术人员理解，如背景技术所言，现有技术无法解决既支持连接态UE接收系统信息更新等消息，又支持空闲态UE和非激活态UE接收寻呼消息调度信息的技术问题。
本申请发明人经研究和分析发现，LTE系统将被寻呼UE的UE标识(Identifier，简称ID)和是否有系统信息更新等消息置于同一寻呼消息中。寻呼消息的调度信息通过寻呼—无线网络临时标识(Paging-Radio Network Temporary Identity，简称P-RNTI)加扰的PDCCH来指示。UE需要先在对应的PO上监听P-RNTI加扰的PDCCH，接收到DCI后再通过DCI指示的调度资源接收PDSCH上的寻呼消息。
具体而言，LTE网络通过DCI发送寻呼控制信息，UE根据自己的UE ID确定寻呼时机。UE只在其对应的PO上监听寻呼控制消息。当LTE网络需要向处于空闲态UE或者非激活态UE发送下行数据(也即呼叫)时，移动管理实体(Mobile Management Entity，简称MME)会向该UE注册的所有跟踪区域(Tracking Area，简称TA)内的所有基站发送寻呼消息，该寻呼消息通知被寻呼UE的UE ID以及用于基站计算UE的寻呼帧(Paging Frame，简称PF)所需的值。之后，基站通过PDSCH发送包含寻呼记录表(PagingRecordList)信息的寻呼消息以寻呼UE。
在处于RRC_IDLE的UE或RRC非激活态(RRC_INACTIVE)态的UE收到寻呼消息后，读取寻呼记录表中被寻呼UE的UE ID。如果UE发现所述寻呼记录表中包含该UE的UE ID，那么UE会发起上行随机接入过程，完成RRC连接建立过程并接收所述下行数据(也即呼叫)。如果所述寻呼记录表中没有该UE的UE ID，则该UE丢弃接收到的寻呼消息，并进入休眠状态。
对处于RRC连接态(RRC-CONNECTED)的UE而言，该UE只需要确认寻呼消息是否包含系统信息更新指示域即可。如果包含系统信息更新指示域，则确认系统信息发生改变，并在系统信息修改周期开始时接收更新的系统信息。如果没有包含系统信息更新指示域，则确认系统信息没有发生改变。
在5G NR系统中，寻呼控制信息仍然通过P-RNTI加扰PDCCH 发送至UE。如果系统信息更新等消息发生变化，则NR基站(也即gNB)可以在每个寻呼时机发送承载系统信息更新等消息的下行控制信息；如果存在被寻呼UE，则gNB需要在被寻呼UE对应的寻呼时机发送承载寻呼消息调度信息指示的下行控制信息。

当前5G技术中，用于承载寻呼控制信息的DCI格式如表1所示。其中，所述短消息指示域置于DCI末尾，仅有1比特。由于短消息指示域仅有1比特，要么支持连接态UE接收系统信息更新等消息，要么支持空闲态UE、非激活态UE接收寻呼消息调度信息指示，因而无法支持连接态UE、空闲态UE以及非激活态UE同时接收各自所需的寻呼控制信息。
本发明实施例提供一种寻呼控制信息的指示方法，所述寻呼控制信息的指示方法包括：确定是否承载第一类寻呼控制信息和第二类寻呼控制信息，所述第一类寻呼控制信息包括系统信息更新通知指示、ETWS通知指示和CMAS通知指示，所述第二类寻呼控制信息包括寻呼消息调度信息指示；根据确定的结果配置DCI的第一预设比特域，所述第一预设比特域为2比特。通过本发明提供的技术方案，可以指示所述寻呼控制信息同时出现所述第一类寻呼控制信息和第二类寻呼控制信息，能够支持连接态UE、空闲态UE、和非激活态UE同时接收并获取对应的寻呼控制信息，节省资源，提高寻呼效率，克服了现有技术存在的缺陷。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例的一种寻呼控制信息的指示方法的流程示意图，该方法适用于网络侧，例如可以由基站执行。参考图1，所述寻呼控制信息的指示方法可以包括以下步骤：
步骤S101：确定是否承载第一类寻呼控制信息和第二类寻呼控制信息，所述第一类寻呼控制信息包括系统信息更新通知指示、ETWS通知指示和CMAS通知指示，所述第二类寻呼控制信息包括寻呼消息调度信息指示；
步骤S102：根据确定的结果配置DCI的第一预设比特域，所述第一预设比特域为2比特。
具体而言，NR基站(也即gNB)在发送寻呼消息之前，首先向UE发送携带寻呼控制信息的DCI。该DCI是经过P-RNTI加扰的下行控制消息。
更具体而言，在步骤S101中，gNB可以确定DCI承载的寻呼控制信息，例如，可以仅承载所述第一类寻呼控制信息、仅承载所述第二类寻呼控制信息，或者同时承载所述第一类寻呼控制信息和所述第 二类寻呼控制信息。
其中，所述第一类寻呼控制信息可以包括系统信息更新通知指示、ETWS通知指示和CMAS通知指示。所述第二类寻呼控制信息可以包括寻呼消息调度信息指示。
更具体而言，如果系统信息发生改变，则gNB需要在DCI中承载系统信息更新通知指示以通知UE接收更新的系统信息；如果存在ETWS信息和/或CMAS信息，则gNB需要在DCI中承载ETWS通知指示和/或CMAS通知指示。
在步骤S102中，根据确定的结果，gNB可以配置DCI的第一预设比特域的比特值，所述第一预设比特域可以为2比特。
具体而言，所述第一预设比特域可以由DCI中常规的1比特短消息指示域扩展得到。也即，现有技术中的短消息指示域为1比特，本实施例中将该1比特的短消息指示域扩展为2比特，由此可以通过不同的配置表示以下多种状态：同时承载所述第一类寻呼控制信息和第二类寻呼控制信息、仅承载所述第一类寻呼控制信息、仅承载所述第二类寻呼控制信息。
进一步，所述第一预设比特域中的其中一比特(例如前一比特)可以用于表示是否承载所述第一类寻呼控制信息，所述第一预设比特域中的另一比特(例如后一比特)可以用于表示是否承载所述第二类寻呼控制信息。
作为一个非限制性实施例，可以将所述第一预设比特域的比特值设置为00或11。当比特值为00或11时，表明DCI中同时承载第一类寻呼控制信息以及第二类寻呼控制信息。
或者，所述第一预设比特域中的第一比特(例如前一比特)可以用于表示是否同时承载所述第一类寻呼控制信息和所述第二类寻呼控制信息；当仅承载所述第一类寻呼控制信息和所述第二类寻呼控制信息其中之一时，所述第一预设比特域中的第二比特(例如后一比特) 用于表示承载的是其中哪一类寻呼控制信息。当第一比特同时承载所述第一类寻呼控制信息和第二类寻呼控制信息时，第二比特的比特值可以忽略，也即其值无论是0还是1都可以。
作为一个非限制性实施例，所述第一预设比特域中的前一比特的比特值为1时表明同时承载第一类寻呼控制信息和第二类寻呼控制信息，前一比特的比特值为0时，表明仅承载了二者其中之一；对于仅承载一类寻呼控制信息的情况，后一比特为0表明承载的是第一类寻呼控制信息，后一比特为1表明承载的是第二类寻呼控制信息。在这种设定下，对于所述第一预设比特域的比特值设置为01的情况，由于前一比特为“0”，表明仅承载了第一类和第二类寻呼控制信息中的一种；进一步，由于后一比特为“1”，表明承载的是第二类寻呼控制信息。类似地，在这种设定下，对于第一预设比特域的比特值设置为10或11的情况，由于前一比特为“1”，表明同时承载第一类寻呼控制信息和第二类寻呼控制信息，此时后一比特的比特值将被忽略。
本领域技术人员理解，所述第一预设比特域承载所述第一类寻呼控制信息和/或所述第二类寻呼控制信息的比特值可以变化出更多实施例，这里不再赘述。例如，在上面的例子中，第一预设比特域中的前一比特和后一比特可以互换，也就是使用后一比特来表示同时承载第一类寻呼控制信息和第二类寻呼控制信息，或者仅承载其中一类，使用前一比特来表示在仅承载其中一类时承载的究竟是哪一类。
进一步，当承载第一类寻呼控制信息时，本实施例还可以配置DCI中的第二预设比特域，以表示被承载的是系统信息更新通知指示、所述ETWS通知指示和所述CMAS通知指示或其他通知指示中的哪一个或者哪几个，其中，第二预设比特域可以为N比特，N≥3，且N为正整数。进一步而言，当DCI中承载所述寻呼控制信息时，DCI中的4比特混合自动重传请求(Hybrid Automatic Repeat Request，简称HARQ)进程号指示域是闲置无用的，因此可以利用4比特HARQ进程号指示域中的N比特作为所述第二预设比特域。
具体而言，当所述第一预设比特域表明承载的第一类寻呼控制信息仅包括系统信息更新通知指示、所述ETWS通知指示和所述CMAS通知指示时，可以采用DCI中的HARQ进程号指示域的高3比特或低3比特作为第二预设比特域，分别表示所述系统信息更新通知指示、所述ETWS通知指示和所述CMAS通知指示。
作为一个非限制性实施例，参考表2，在选定的HARQ进程号指示域中，可以选择所述HARQ进程号指示域的高3比特承载所述系统信息更新通知指示、所述ETWS通知指示和所述CMAS通知指示，具体地，可以采用比特映射方式指示。例如，最高位比特用于指示系统信息更新通知指示；第二高位比特用于指示ETWS通知指示，第三高位比特用于指示CMAS通知指示。
作为又一个非限制性实施例，参考表2，可以选择所述HARQ进程号指示域的低3比特承载所述系统信息更新通知指示、所述ETWS通知指示和所述CMAS通知指示。具体地，同样可以采用比特映射方式指示。例如，最低位比特用于指示系统信息更新通知指示；第二低位比特用于指示ETWS通知指示，第三低位比特用于指示CMAS通知指示。
本领域技术人员理解，在选定的HARQ进程号指示域中，映射所述系统信息更新通知指示、所述ETWS通知指示和所述CMAS通知指示的顺序可以变化，这里不再赘述。
本领域技术人员理解，当所述第一类寻呼控制信息除包括系统信息更新通知指示、所述ETWS通知指示和所述CMAS通知指示外，还可以包括其他通知指示信息，此时，可以采用所述HARQ进程号的所有比特实现对第一类寻呼控制信息的指示。例如，所述第一类寻呼控制信息包含的通知指示信息超过4个时，还可以利用常规DCI中的2比特下行链路配置索引域进行指示。
进一步地，所述第一预设比特域可以置于DCI的时频资源域前。
表2
Figure PCTCN2018124136-appb-000002
具体而言，参考表2，可以将短消息指示域扩展得到的所述第一预设比特域设置在DCI的频域资源配置和时域资源配置之前。
进一步，可以将所述寻呼消息的资源分配信息按照现有方式置于DCI的频域资源配置域和时域资源配置域。
作为一个变化例，所述第一预设比特域可以为DCI包含的2比特下行链路配置索引域。具体地，gNB可以基于所述下行链路配置索引域表示同时承载所述第一类寻呼控制信息和第二类寻呼控制信息、仅承载所述第一类寻呼控制信息和仅承载所述第二类寻呼控制信息。 具体的比特值设置方式可以参考由DCI域中的1比特短消息指示域扩展得到的第一预设比特域时的比特值设置方式，这里不再赘述。
进一步，参考表3，如果将所述下行链路配置索引域作为所述第一预设比特域，则可以省略DCI中的短消息指示比特域，以节省下行控制资源。
表3
Figure PCTCN2018124136-appb-000003
进一步，当承载第一类寻呼控制消息时，可以配置DCI中的第二比特域，第二比特域中包含N比特，其中，N≥3，且N为正整数。当所述第一类寻呼控制信息仅包括3种通知指示时，所述第二比特域可以分别用于表示是否承载所述系统信息更新通知指示、所述ETWS 通知指示和所述CMAS通知指示。参考表3，当所述第一预设比特域表明承载的第一类寻呼控制信息仅包括3种通知指示时，可以采用DCI中的HARQ进程号指示域的高3比特或低3比特作为第二预设比特域，分别表示所述系统信息更新通知指示、所述ETWS通知指示和所述CMAS通知指示。
其中，1比特用于指示所述系统信息更新通知指示、1比特用于指示所述ETWS通知指示、1比特用于指示和所述CMAS通知指示。具体实施方式可以参考表3，这里不再赘述。
作为又一个变化例，参考表4，所述第一预设比特域可以为所述1比特短消息指示域再结合下行链路配置索引域中的高1比特或低1比特或结合1比特DCI格式指示域。由此，所述第一预设比特域仍为2比特。本领域技术人员理解，所述1比特短消息指示域可以置于DCI的频域资源配置域和时域资源配置域之前。
具体而言，所述第一预设比特域中的短消息指示域可以用于表示是否承载所述第一类寻呼控制信息，所述第一预设比特域中的下行链路配置索引域的高1比特或低1比特或者1比特DCI格式指示域可以用于表示是否承载所述第二类寻呼控制信息。
或者，所述第一预设比特域由所述下行链路配置索引域的其中1比特或1比特DCI格式指示域表示所述寻呼控制信息同时承载所述第一类寻呼控制信息和所述第二类寻呼控制信息，或者仅承载所述第一类寻呼控制信息和所述第二类寻呼控制信息其中之一。当仅承载所述第一类寻呼控制信息和所述第二类寻呼控制信息其中之一时，所述第一预设比特域中的短消息指示域可以用于表示承载的是其中哪一类寻呼控制信息。
或者所述第一预设比特域由所述短消息指示域表示所述寻呼控制信息同时承载所述第一类寻呼控制信息和所述第二类寻呼控制信息，或者仅承载所述第一类寻呼控制信息和所述第二类寻呼控制信息其中之一。当仅承载所述第一类寻呼控制信息和所述第二类寻呼控制 信息其中之一时，所述第一预设比特域中的下行链路配置索引域的其中1比特或1比特DCI格式指示域可以用于表示承载的是其中哪一类寻呼控制信息。
表4

下面以所述下行链路配置索引域的其中1比特或1比特DCI格式指示域表示所述寻呼控制信息同时承载所述第一类寻呼控制信息和所述第二类寻呼控制信息，或者仅承载所述第一类寻呼控制信息和所述第二类寻呼控制信息其中之一为例，对所述第一预设比特域的比 特值设置方式进行说明。
具体而言，所述下行链路配置索引域的高1比特或低1比特或者1比特DCI格式指示域设置为0时，指示所述寻呼控制信息中同时承载第一类寻呼控制信息和第二类寻呼控制信息；反之，仅承载第一类寻呼控制信息或仅承载第二类寻呼控制信息。当然，具体的比特值的设置可以根据需要做变化，例如0和1互换。
进一步地，当所述寻呼控制信息指示仅承载第一类寻呼控制信息或仅承载包含第二类寻呼控制信息时，可以采用所述短消息指示域指示，否则忽略所述短消息指示域。
作为一个非限制性实施例，可以采用比特0指示仅承载第一类寻呼控制信息；也可以采用比特1指示仅承载第二类寻呼控制信息。本领域技术人员理解，具体实施时，可以采用不同的比特值表示承载的是所述第一类寻呼控制信息，还是所述第二类寻呼控制信息。
进一步，参考表4，当所述第一预设比特域表明承载的第一类寻呼控制信息仅包括所述系统信息更新通知指示、所述ETWS通知指示和所述CMAS通知指示时，可以采用DCI中的HARQ进程号指示域的高3比特或低3比特作为第二预设比特域，分别表示所述系统信息更新通知指示、所述ETWS通知指示和所述CMAS通知指示。
3个比特中，1比特用于指示所述系统信息更新通知指示、1比特用于指示所述ETWS通知指示、1比特用于指示和所述CMAS通知指示。具体实施方式可以参考表2，这里不再赘述。
进一步，如表4所示，可以将短消息指示域设置在DCI的频域资源配置和时域资源配置之前。
进一步，可以将所述寻呼消息的资源分配信息按照现有方式置于DCI的频域资源配置域和时域资源配置域。
本领域技术人员理解，所述第二比特域的比特数量与所述第一类寻呼控制信息包含的通知指示的数量有关，随着包含的通知指示的数 量的增长而增长，具体实施时可以参考前文，这里不再赘述。
图2是本发明实施例的一种寻呼控制信息的接收方法的流程示意图，该方法可以适用于UE侧，例如由UE执行。参考图2，所述接收方法可以包括以下步骤：
步骤S201：接收DCI；
步骤S202：对所述DCI的第一预设比特域进行解析，以确定所述DCI中是否承载第一类寻呼控制信息和第二类寻呼控制信息，所述第一类寻呼控制信息包括系统信息更新通知指示、ETWS通知指示和CMAS通知指示，所述第二类寻呼控制信息包括寻呼消息调度信息指示，所述第一预设比特域为2比特。
具体而言，在步骤S201中，UE可以从网络侧接收PDCCH传输的DCI消息。
在步骤S202中，UE可以对所述DCI进行解调、译码。如果所述DCI包括第一预设比特域，则在解析所述第一预设比特域之后确定所述DCI中是否承载第一类寻呼控制信息和第二类寻呼控制信息。
进一步地，所述第一预设比特域可以是由短消息指示域扩展得到的，或者，所述第一预设比特域为下行链路配置索引域，或者，所述第一预设比特域为下行链路配置索引域中的1比特以及短消息指示域，或者，所述第一预设比特域为1比特DCI格式指示域以及1比特短消息指示域。
进一步地，如果所述DCI承载所述第一类寻呼控制信息，则解析所述DCI中的第二预设比特域，所述第二预设比特域为N比特，其中N≥3，且N为正整数。
进一步地，所述第二预设比特域为HARQ进程号指示域的高N比特或低N比特。进一步地，所述第二预设比特域中的N比特可以分别用于表示所述系统信息更新通知指示、所述ETWS通知指示和所述CMAS通知指示。
进一步地，所述第一预设比特域中的第一比特用于表示是否承载所述第一类寻呼控制信息，所述第一预设比特域中的第二比特用于表示是否承载所述第二类寻呼控制信息。
进一步地，所述第一预设比特域中的第一比特用于表示是否同时承载所述第一类寻呼控制信息和所述第二类寻呼控制信息，当仅承载所述第一类寻呼控制信息和所述第二类寻呼控制信息其中之一时，所述第一预设比特域中的第二比特用于表示承载的是其中哪一类寻呼控制信息。
本领域技术人员理解，所述步骤S201和步骤S202与上述图1所示实施例中的寻呼控制信息指示方法呼应，两者在具体的实现原理和逻辑上是相辅相成的。因而，关于UE侧的寻呼控制信息接收方法可以一并参考图1所示实施例的相关描述，这里不再赘述。
由上，通过本发明实施例提供的技术方案，可以支持连接态UE、空闲态UE和非激活态UE同时接收并获取各自所需的寻呼消息，有利于节省资源，提高寻呼效率，可以克服现有技术的缺陷。
