Description

无线通信方法、设备、芯片和系统 技术领域
本发明实施例涉及通信领域，并且更具体地，涉及无线通信方法、设备、芯片和系统。
背景技术
随着人们对速率、延迟、高速移动性、能效的追求，以及未来生活中业务的多样性和复杂性的需求。第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)国际标准组织开始研发第五代移动通信技术(5-Generation，5G)。
在5G新空口(New Radio,NR)早期部署时，5G NR的用户设备(User Equipment，UE)和长期演进(Long Term Evolution，LTE)的UE类似，首先会到核心网络进行附着注册，然后核心网络处存在UE的上下文信息，其中一个信息就是位置区域信息(TA list)，当存在该UE的寻呼时，核心网络在该TA list所在的所有基站下发寻呼消息，并触发这些基站在该基站下的所有小区下发对该UE的寻呼。所以一个UE的寻呼范围至少为一个TA list范围内所有小区下发寻呼消息。
对于寻呼消息的收取过程，LTE和NR类似，UE需要在公共搜索空间监听寻呼无线网络临时标识(Paging Radio Network Temporary Identifier，P-RNTI)，然后获取寻呼消息的调度信息，然后解码寻呼消息对应的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)获取寻呼消息的内容。寻呼消息中可能包含系统广播变更的指示信息，也可能包含被寻呼UE的标识列表信息，或者同时包含二者信息。
目前，为了降低UE解码寻呼消息的负荷，将寻呼(paging)物理下行控制信道(Physical Downlink Control Channel，PDCCH)分为长消息(long message)和短消息(short message)。
其中，long message包括Paging PDCCH和paging PDSCH，并且如果存在系统广播的变更指示信息，则该变更指示信息必须包含在寻呼消息(paging PDSCH)中，由此，终端设备需要知道paging PDSCH本身是否包含系统广播变更指示信息时，必须先对paging PDSCH进行解码。
由此可以发现，采用上述技术方案时，对于连接态的UE来说，UE监听寻呼消息的主要目的是获取系统广播变更指示信息，进而获取更新的系统广播信息。但是，一个小区的系统广播变更是一个不频繁的过程。所以连接态的UE在采用long message的情况下，需要总是解码Paging PDSCH获取系统广播变更指示信息，即使当前paging消息中并没有包含系统广播指示信息，连接态的UE也需要解码paging PDSCH获取该信息来验证是否存在系统广播变更指示信息，浪费UE的电力并增加复杂度。
因此，UE如何降低寻呼过程中UE的复杂度并以及耗电是急需解决的问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
图1是本申请实施例的一个应用场景的示意图。
如图1所示，通信系统100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解，本发明实施例仅以通信系统100进行示例性说明，但本发明实施例不限定于此。也就是说，本发明实施例的技术方案可以应用于各种通信 系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、新无线(New Radio，NR)或未来的5G系统等。
以5G系统为例，本申请实施例的技术方案可以应用于广域的长期演进(Long Term Evolution，LTE)覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下，可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用，而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期在LTE投资，提出了LTE和NR之间紧密连接(tight interworking)的工作模式。
5G的主要应用场景包括：增强移动超宽带(Enhance Mobile Broadband，eMBB)、低时延高可靠通信(Ultra-Reliable and Low Latency Communication，URLLC)、大规模机器类通信(massive machine type of communication，mMTC)。其中，eMBB以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。由于eMBB可能部署在不同的场景中。例如，室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，可以结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
此外，由于完整的5G NR覆盖很难获取，因此，本发明实施例的网络覆盖可以采用广域的长期演进(Long Term Evolution，LTE)覆盖和NR的孤岛覆盖模式。同时，为了保护移动运营商前期在LTE投资，进一步地可以采用LTE和NR之间紧密连接(tight interworking)的工作模式。
在图1所示的通信系统100中，网络设备120可以是与终端设备110通信的接入网设备。接入网设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备110(例如UE)进行通信。
例如，该接入网设备可以是全球移动通讯(Global System of Mobile  communication，GSM)系统或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)系统中的演进型基站(Evolutional Node B，eNB或eNodeB)。
可选地，该接入网设备还可以是下一代无线接入网(Next Generation Radio Access Network，NG RAN)，或者是NR系统中的基站(gNB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该接入网设备可以为中继站、接入点、车载设备、可穿戴设备，或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该终端设备110可以是任意终端设备，该终端设备110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网(Core Network)进行通信，也可称为接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。例如，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及5G网络中的终端设备等。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。
图2示出了根据本申请实施例的无线通信方法200的示意性流程图，该方法200可以由终端设备和网络设备执行。图2中所示的终端设备可以是如图1所示的处于连接态的终端设备，图2中所示的网络设备可以是如图1所示的接入网设备。该方法200包括以下部分或全部内容：
如图2所示，该方法200包括：
S210，网络设备生成第一指示信息，该第一指示信息用于指示寻呼消息中是否存在系统广播的变更指示信息。
S220，该网络设备向终端设备发送该第一指示信息。
S230，该终端设备根据该第一指示信息，确定是否接收该网络设备发送的该寻呼消息。
具体地，从终端设备的角度来说，终端设备接收网络设备发送的第一指示信息，该终端设备根据该第一指示信息，确定是否接收该网络设备发送的该寻呼消息。换句话说，从网络设备的角度来说，该网络设备生成该第一指示信息，并向处于连接态的终端设备发送该第一指示信息。
本发明实施例中，通过网络设备发送的该第一指示信息，使得连接态的终端设备能够在当前寻呼消息中并没有包含系统广播的变更指示信息的情况下，避免获取并解码寻呼消息来验证是否存在系统广播变的更指示信息，能够降低UE的复杂度并以及耗电。
应理解，本发明实施例中，对寻呼消息的具体传输形式不作限定。
例如，可以采用多波束(beam)形式，具体地，为了寻呼到UE，可以在每个小区的每个beam下发送寻呼消息。例如，对于一个高频部署的小区来说，例如64个，所以在一个小区里面的寻呼需要发送64次。
在一个实施例中，该第一指示信息用于指示该寻呼消息中不存在该变更指示信息时，该终端设备确定不接收该寻呼消息。
在另一个实施例中，该第一指示信息用于指示该寻呼消息中存在该变更指示信息时，该终端设备确定接收该寻呼消息；由此，该终端设备可以接收并解码该寻呼消息，以得到该变更指示信息。
可选地，该第一指示信息为第一数值时，该第一指示信息用于指示该寻呼消息中不存在该变更指示信息，该第一指示信息为第二数值时，该第一指示信息用于指示该寻呼消息中存在该变更指示信息。
例如，如果paging消息中不存在系统广播的变更指示信息，则该指示位设置为0，否则设置为1。
又例如，如果paging消息中不存在系统广播的变更指示信息，则该指示位设置为1，否则设置为0。
应理解，上述第一指示信息仅为示例，本发明实施例不限于此。例如，该第一指示信息还可以为其他形式的显示指示或者隐式指示方式。
可选地，该终端设备接收该网络设备发送的物理下行控制信道PDCCH，该PDCCH包括该第一指示信息和调度信息，该调度信息用于指示该寻呼消息在物理下行共享信道PDSCH中的资源位置。具体地，连接态的UE盲检P-RNTI加扰的PDCCH，如果该第一指示信息为指示后面的paging消息中不存在系统广播变更指示信息，则连接态的UE不收取对应的paging消息，否 则就获取paging消息。换句话说，从该网络设备的角度来说，该网络设备向该终端设备发送物理下行控制信道PDCCH，该PDCCH包括该第一指示信息和调度信息，该调度信息用于指示该寻呼消息在物理下行共享信道PDSCH中的资源位置。
在实际流程中，如果网路设备发送寻呼消息的调度信息，且该调度信息后面存在paging消息。则在paging PDCCH中添加一个指示位，指示后面的寻呼消息中是否存在系统广播的变更指示信息。应理解，paging PDCCH可以理解为寻呼消息对应的PDCCH，
由此，本发明实施例中，UE需要在公共搜索空间监听P-RNTI，然后获取寻呼消息的调度信息和该第一指示信息，然后根据该第一指示信息确定是否接收并解码寻呼消息对应的PDSCH以获取寻呼消息的内容。在确定并解码寻呼消息对应的PDSCH以获取寻呼消息的内容时，根据该调度信息接收并解码寻呼消息，以获取系统广播变更的指示信息。
应理解，本发明实施例中，该第一指示信息和调度信息可以分别携带在PDCCH中，该第一指示信息也可以携带在调度信息中，并且该调度信息携带在PDCCH中，本发明实施例不作具体限定。
以上结合附图详细描述了本申请的优选实施方式，但是，本申请并不限于上述实施方式中的具体细节，在本申请的技术构思范围内，可以对本申请的技术方案进行多种简单变型，这些简单变型均属于本申请的保护范围。
例如，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合，为了避免不必要的重复，本申请对各种可能的组合方式不再另行说明。
又例如，本申请的各种不同的实施方式之间也可以进行任意组合，只要其不违背本申请的思想，其同样应当视为本申请所公开的内容。
应理解，在本申请的各种方法实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
上文结合图2，详细描述了本申请的方法实施例，下文结合图3至图6，详细描述本申请的装置实施例。
图3是本发明实施例的终端设备300的示意性框图。
具体地，如图3所示，该终端设备300可以包括：
