具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本发明的实施例。本发明实施例提供的系统运行模式确定方法和终端可以应用于无线通信系统中。该无线通信系统可以为新空口(New Radio，NR)系统，或者其他系统，例如：LTE演进(LTE-Advanced，LTE-A)系统或者长期演进(Long Term Evolution，LTE)系统，或者后续演进通信系统等。
请参见图1，图1是本发明实施例可应用的一种网络系统的结构图，如图1所示，包括终端11和网络设备12，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端侧设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或者机器人等终端侧设备，需要说明的是，在本发明实施例中并不限定终端11的具体类型。上述网络设备12可以是4G基站，或者5G基站，或者以后版本的基站，或者其他通信系统中的基站，或者称之为节点B，演进节点B，或者传输接收点(Transmission Reception Point，TRP)，或者接入点(Access Point，AP)，或者所述领域中其他词汇，只要达到相同的技术效果，所述网络设备不限于特定技术词汇。另外，上述网络设备12可以是主节点(Master Node，MN)，或者辅节点(Secondary Node，SN)。需要说明的是，在本发明实施例中仅以5G基站为例，但是并不限定网络设备的具体类型。
请参见图2，图2是本发明实施例提供的一种系统运行模式确定方法的流程图，该方法应用于终端，如图2所示，包括以下步骤：
步骤201、获取第一信息，其中，所述第一信息为所述终端检测或者接收到的信息。
其中，上述获取第一信息可以是终端工作频段包括第一频段的情况下，获取第一信息，例如：终端通过检测或者接收，以得到上述第一信息。
需要说明的是，上述第一信息为所述终端检测或者接收到的信息是指，终端通过检测或者接收的操作确定的信息。例如：地理位置信息、同步信号块(synchronization signal block，SSB)或者其他下行信号等。
步骤202、依据所述第一信息，确定所述终端在第一频段的系统运行模式，其中，所述系统运行模式包括授权模式或者非授权模式。
上述依据所述第一信息，确定所述终端在所述第一频段的系统运行模式可以是，将第一信息显式或者隐式指示的系统运行模式确定为在所述第一频段的系统运行模式。例如：第一信息显式或者隐式指示第一频段为授权频段，从而确定授权模式，或者第一信息显式或者隐式指示第一频段为非授权频段，从而确定非授权模式。
需要说明的是，本发明实施例中，非授权模式也可称为共享频域接入模式或者共享传输模式。
本发明实施例中，通过上述第一信息可以准确地确定终端在所述第一频段的系统运行模式，以避免终端的系统运行模式错误。
作为一种可选的实施方式，上述第一信息为所述终端检测到的地理位置信息；所述依据所述第一信息，确定所述终端在所述第一频段的系统运行模式，包括：
依据所述地理位置信息所属的位置区域，确定所述终端在所述第一频段的系统运行模式。
其中，上述地理位置信息可以是终端通过定位系统(例如GPS，北斗系统等)获取终端目前所在地理位置(例如：国家或者地区)信息。从而，终端根据所在地理位置确定第一频段为授权频段或者非授权频段，进而确定该频段系统运行模式。
需要说明的是，针对上述第一频段不同国家或者地区的配置可能不同，例如：一些国家或者地区将上述第一频段配置为授权频段，而另一个国家或者地区将上述第一频段配置为非授权频段。例如：针对6/60GHz频段一些国家配置为非授权频段，则另一些国家配置为授权频段。这样，可以根据上述地理位置信息确定终端在所述第一频段的系统运行模式。
一个例子如下：
终端在初始接入前通过定位系统(例如GPS，北斗系统等)获得目前所在地理位置(国家或者地区)信息，终端根据所在地理位置(国家或者地区)的上述第一频段授权模式确定该频段系统运行方式，根据确定的频段系统运行方式进行初始接入以及后续处理流程。假如终端在初始接入时无定位信号，则可以使用最近一次定位信息或者最近一次接入系统的运行模式来确定运行模式进行接入。
作为一种可选的实施方式，上述第一信息为所述终端在所述第一频段初始接入时检测的SSB的相关信息；
其中，所述第一频段被分配为授权频段时所述SSB的相关信息与所述第一频段被分配为非授权频段时所述SSB的相关信息不同。
上述SSB的相关信息可以是与SSB存在关联的信息。
该实施方式中，可以通过SSB的不同相关信息为指示上述第一频段的系统运行模式。
可选地，所述SSB的相关信息包括如下至少一项：
所述SSB的同步栅格(sync raster)频点位置；
所述SSB的信道编号；
所述SSB的主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)和解调参考信号(demodulation reference signal，DMRS)中至少一项的特征信息；
所述SSB的时域位置；
所述SSB的索引；
所述SSB的候选索引；
所述SSB的有效载荷，其中，所述有效载荷用于指示所述第一频段为授权频段或者非授权频段。
其中，上述SSB的同步栅格频点位置可以是，预先对上述第一频段上的同步栅格频点进行分类，一部分只能作为授权模式下的SSB发送，另一部分只能作为非授权模式下的SSB发送，从而可以准确地确定系统运行模式。同理，可以配置一部分信道作为授权模式下的SSB发送，另一部分信道只能作为非授权模式下的SSB发送。进一步地，上述信道编号可以是全局同步信道 编号(Global Synchronization Channel Number，GSCN)。
一个例子如下：
对于第一频段定义的同步栅格(对应于一组GSCN频点编号)，明确一部分同步栅格频点集合S1为授权模式系统SSB发送频点位置，另一部分同步栅格频点集合S2为非授权模式系统SSB发送频点位置。具体实现来说，定义两个频带(band)号，一个band号对应授权模式，另一个band号对应非授权模式。如对第一个band和第二个band分别定义同步栅格S1和S2，同时它们是正交的没有交集。终端在该两个频带上定义的所有同步栅格上进行搜索，确定发送频带号从而确定授权模式。当检测到的PSS和SSS在非授权模式系统SSB发送频点时，则终端按照非授权模式定义的流程进行初始接入流程和后续操作；否则均按照授权模式进行。
更进一步，可以结合上述地理位置信息，当终端能够得到位置信息并且知道该位置信息对应国家/地区该频谱的授权方式时，则只在该授权方式对应的同步栅格上进行SSB的搜索检测，这样能减少功耗。
上述PSS、SSS和DMRS中至少一项的特征信息可以是，每项独立的特征信息，也可以是多项之间的共同特征信息。例如：所述SSB的PSS、SSS和DMRS中至少一项的特征信息包括如下至少一项：
所述PSS和所述SSS的频域位置关系；
所述PSS和所述SSS的时域位置关系；
所述PSS和所述SSS的相位差；
所述PSS的循环移位；
所述SSS的循环移位
所述PSS的序列；
所述SSS的序列；
所述DMRS的相位；
所述DMRS的循环移位。
例如：PSS和SSS的时域或者频域位置关系中，如果PSS在前，SSS在后为授权模式运行；PSS在后，SSS在前为非授权模式运行，当然，这里仅是举例。
例如：通过配置所述PSS和所述SSS的不同的相位差，以区分授权模式和非授权模式。同样，可以配置所述PSS的循环移位，所述SSS的循环移位不同，以区分授权模式和非授权模式，以及还可以配置PSS和SSS的循环移位的不同，以区分授权模式和非授权模式。
另外，可以配置PSS和/或SSS的序列不同，以区分授权模式和非授权模式。例如一部分PSS/SSS序列用于授权模式传输，另一部分PSS/SSS序列用于非授权模式传输。
同理，还可以配置DMRS的相位或者循环移位不同，以区分授权模式和非授权模式。进一步，上述DMRS可以是物理广播信道(Physical Broadcast Channel，PBCH)的DMRS。
一个例子如下：
协议规定PSS和SSS相关的特征信息传递系统运行模式信息，其中：
当利用PSS和SSS的位置关系传递系统运行模式信息时，终端在该频带定义的所有同步栅格(sync raster)上进行SSB上的PSS和SSS检测，通过检测到的SSS位置相对于PSS的相对位置关系确定系统运行模式为授权或非授权；或者
当利用PSS和SSS的相位差或者循环移位差传递系统运行模式信息时，终端在该频带定义的所有同步栅格上进行SSB上的PSS检测，通过检测到的PSS和SSS的相位差或者循环移位差确定系统运行模式为授权或非授权；或者
当利用PSS和SSS的序列传递运行模式信息时，协议规定一组PSS/SSS序列用于授权模式传输，另一组PSS/SSS序列用于非授权模式传输，终端在该频带定义的所有同步栅格上进行SSB上的PSS/SSS检测，通过检测到的PSS/SSS的序列确定系统运行模式为授权或非授权。
而上述SSB的时域位置、索引(SSB index)和候选索引(Candidate SSB index)可以是，终端在上述第一步骤初始接入时检测到的SSB的时域位置、索引(SSB index)和候选索引(Candidate SSB index)信息。例如：假设授权模式的SSB处于前半帧，非授权模式的SSB处于后半帧，或者假设SSB index0-8用于授权模式传输，SSB index 9-20用于非授权模式传输。
一个例子如下：
协议规定在现有帧结构的特定时间位置发送授权系统/非授权系统的SSB。终端在该频带定义的所有同步栅格(sync raster)上进行SSB检测，并且根据解码的SSB信息获取定时信息，根据该SSB的定时信息确定它所属的特定时间位置(例如前半帧或者SSB index)来确定系统运行模式为授权或非授权。
而上述SSB的有效载荷(payload)可以是，通过该有效载荷显示指示授权模式或者非授权模式，如通过PBCH中的预留比特(reserved bit)示授权模式或者非授权模式。
该实施方式中，由于通过SSB的相关信息指示授权模式或者非授权模式，这样不需要增加额外的信令，以节约传输开销。
作为一种可选的实施方式，所述第一信息为所述终端在所述第一频段初始接入时接收到的系统信息，所述系统信息用于指示所述第一频段为授权频段或者非授权频段。
其中，上述系统信息可以是系统消息，例如：系统消息块(System Information Block，SIB)。
可选地，上述系统信息显示或者隐示指示所述第一频段为授权频段或者非授权频段。其中，隐示指示可以是通过系统信息的频带(band)信息隐示指示第一频段为授权频段或者非授权频段。进一步地，如果授权模式和非授权模式的SSB检测过程不一致时，终端可以分别按照授权模式和非授权模式的SSB检测过程检测SSB，并分别按照这两种SSB检测过程检测到的SSB进行盲检，以在其中一种盲检下得到上述系统消息，如SIB消息，进而确定系统运行模式；或者如果授权模式和非授权模式的主信息块(Master Information Block，MIB)信息不一致时，终端可以分别按照授权模式和非授权模式的MIB信息进行盲检，以在其中一种盲检下得到上述系统消息，如SIB消息，进而确定系统运行模式。
例如：可以通过系统的MIB信息、SIB信息或者RRC信息显示指示该系统运行模式为授权或非授权。其中，终端可以通过SIB信息中的band信息确认系统运行模式，即协议可以为同一频段对于授权模式和非授权模式分别进行编号。
作来一种可选的实施方式，所述第一信息为所述终端通过第二频段接收到的信息。
其中，上述信息可以为所述终端通过第二频段接收到的控制信息。例如：广播SIB或者无线资源控制(Radio Resource Control，RRC)配置信息等。
另外，上述第二频段和第一频段可以是不同载波或者不同小区的频段，例如：上述第二频段为主小区(Primary Cell，PCell)，第一频段为个辅小区(Secondary Cell，SCell)。
该实施方式中，由于可以通过第二频段获取第一信息，从而更加有效地保证终端系统运行模式不出错。
本发明实施例中，获取第一信息，其中，所述第一信息为所述终端检测或者接收到的信息；依据所述第一信息，确定所述终端在所述第一频段的系统运行模式，其中，所述系统运行模式包括授权模式或者非授权模式。这样可以避免终端系统运行模式错误。

获取模块301，用于获取第一信息，其中，所述第一信息为所述终端检测或者接收到的信息；

用户输入单元407可用于接收输入的数字或字符信息，以及产生与终端的用户设置以及功能控制有关的键信号输入。具体地，用户输入单元407包括触控面板4071以及其他输入设备4072。触控面板4071，也称为触摸屏，可收集用户在其上或附近的触摸操作(比如用户使用手指、触笔等任何适合的物体或附件在触控面板4071上或在触控面板4071附近的操作)。触控面板4071可包括触摸检测装置和触摸控制器两个部分。其中，触摸检测装置检测用户的触摸方位，并检测触摸操作带来的信号，将信号传送给触摸控制器； 触摸控制器从触摸检测装置上接收触摸信息，并将它转换成触点坐标，再送给处理器410，接收处理器410发来的命令并加以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型实现触控面板4071。除了触控面板4071，用户输入单元407还可以包括其他输入设备4072。具体地，其他输入设备4072可以包括但不限于物理键盘、功能键(比如音量控制按键、开关按键等)、轨迹球、鼠标、操作杆，在此不再赘述。
进一步地，触控面板4071可覆盖在显示面板4061上，当触控面板4071检测到在其上或附近的触摸操作后，传送给处理器410以确定触摸事件的类型，随后处理器410根据触摸事件的类型在显示面板4061上提供相应的视觉输出。虽然在图4中，触控面板4071与显示面板4061是作为两个独立的部件来实现终端的输入和输出功能，但是在某些实施例中，可以将触控面板4071与显示面板4061集成而实现终端的输入和输出功能，具体此处不做限定。
接口单元408为外部装置与终端400连接的接口。例如，外部装置可以包括有线或无线头戴式耳机端口、外部电源(或电池充电器)端口、有线或无线数据端口、存储卡端口、用于连接具有识别模块的装置的端口、音频输入/输出(I/O)端口、视频I/O端口、耳机端口等等。接口单元408可以用于接收来自外部装置的输入(例如，数据信息、电力等等)并且将接收到的输入传输到终端400内的一个或多个元件或者可以用于在终端400和外部装置之间传输数据。
存储器409可用于存储软件程序以及各种数据。存储器409可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器409可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
处理器410是终端的控制中心，利用各种接口和线路连接整个终端的各个部分，通过运行或执行存储在存储器409内的软件程序和/或模块，以及调用存储在存储器409内的数据，执行终端的各种功能和处理数据，从而对终端进行整体监控。处理器410可包括一个或多个处理单元；优选地，处理器 410可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器410中。
终端400还可以包括给各个部件供电的电源411(比如电池)，优选地，电源411可以通过电源管理系统与处理器410逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
另外，终端400包括一些未示出的功能模块，在此不再赘述。
优选地，本发明实施例还提供一种终端，包括处理器410，存储器409，存储在存储器409上并可在所述处理器410上运行的计算机程序，该计算机程序被处理器410执行时实现上述系统运行模式确定方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
本发明实施例还提供一种计算机可读存储介质，计算机可读存储介质上存储有计算机程序，该计算机程序被处理器执行时实现本发明实施例提供的系统运行模式确定方法，且能达到相同的技术效果，为避免重复，这里不再赘述。其中，所述的计算机可读存储介质，如只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本发明各个实施例所述的方法。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本发明的保护之内。
