Description

一种通信方法及相关装置 技术领域
本申请涉及无线通信技术领域，尤其涉及一种通信方法及相关装置。
背景技术
无线通信系统中，安全传输是通信的基础保障。安全传输可以基于密钥实现，例如可以分为对称加密和非对称加密。密钥维护管理需要复杂的协议支持，会产生额外的通信开销和时延，无法适配未来通信网络的高动态特性。并且在当前无线通信协议中，物理层和媒体接入控制(medium access control，MAC)层的控制信令是在密钥协商之前传输的，无法采用基于密钥的安全通信手段。因此，可以采用无密钥安全传输的方法，以防止通信传输被分散式阻断服务攻击(distributed denial-of-service，DDoS)、篡改和侦听等攻击。
无密钥安全传输的方法需要建立合法链路和非法链路的误码差异性，也就是说非法用户的误包率(packet error rate，PER)需要大于一定阈值。当前可以基于模型估计PER，例如基于无线传播模型和接收机参考模型通过仿真和理论计算得到PER。然而在实际的无线系统中，由于无线环境的高动态性、场景的多样性等因素，基于模型估计PER的准确性无法得到保证。因此，如何提高PER确定的准确性是亟待解决的问题。

在本申请提供的方案中，网络设备通过向第一终端设备发送第一传输参数，第一传输参数为网络设备与第二终端设备之间传输数据所用的传输参数，第一终端设备与第二终端设备为不同的终端设备，根据第一传输参数解调第一参考信号。网络设备将第二终端设备的传输参数共享发送给第一终端设备，以使第一终端设备能够解调第一参考信号，从而可以得到第一终端设备的PER。可以理解为，以第一终端设备作为第二终端设备的“EVE”(eavesdropper)，协助统计“EVE”的PER，从而可以提高确定误码率的准确性，从而可以解决基于模型仿真或理论计算误码率在实际高动态性、场景的多样性的无线环境中难以保证准确性的问题。
在一种可能的实现方式中，该通信方法还包括：第一终端设备向网络设备发送PER，该PER根据第一传输参数解调第一参考信号确定。
在本申请提供的方案中，可以由第一终端设备确定PER，并向网络设备上报该PER，以使网络设备确定第一终端设备的PER。
在一种可能的实现方式中，该通信方法还包括：第一终端设备向网络设备发送指示信息， 该指示信息用于指示根据第一传输参数解调第一参考信号是否成功。
在本申请提供的方案中，可以由第一终端设备根据第一传输参数解调第一参考信号后，向网络设备上报解调结果，由网络设备根据解调结果确定PER。
在一种可能的实现方式中，该通信方法还包括：第一终端设备向网络设备发送请求信息，该请求信息用于请求网络设备发送第一传输参数。
第一传输参数可以是第一终端设备向网络设备发送请求信息请求发送的，也可以是网络设备自行向第一终端设备发送的。可选地，若是网络设备自行向第一终端设备发送的，可以在向第一终端设备发送第一传输参数之前，先告知第一终端设备，以使第一终端设备能够及时接收到第一传输参数。
在一种可能的实现方式中，第一参考信号承载第一传输信息，第一传输信息根据第一传输参数进行调制。

为了便于理解本申请实施例，下面先介绍一下目前关于安全传输的实现包括多种技术方案，以下示例性的进行说明。
无线通信系统中，安全传输是通信的基础保障。安全传输可以基于密钥实现，例如可以分为对称加密和非对称加密。密钥维护管理需要复杂的协议支持，会产生额外的通信开销和时延，无法适配未来通信网络的高动态特性。并且在当前无线通信协议中，物理层和媒体接入控制(medium access control，MAC)层的控制信令是在密钥协商之前传输的，无法采用基于密钥的安全通信手段。因此，可以采用无密钥安全传输的方法，以防止通信传输被分散式阻断服务攻击(distributed denial-of-service，DDoS)、篡改和侦听等攻击。
无密钥安全传输的方法需要建立合法链路和非法链路的误码差异性，也就是说非法用户 的误包率(packet error rate，PER)需要大于一定阈值。
当前可以基于模型估计PER，例如基于无线传播模型和接收机参考模型通过仿真和理论计算得到PER。然而在实际的无线系统中，由于无线环境的高动态性、场景的多样性等因素，基于模型估计PER的准确性无法得到保证。因此，如何提高PER确定的准确性是亟待解决的问题
基于估计PER的准确性无法得到保证的问题，本申请实施例提供一种通信方法，通过网络设备向第一终端设备发送第一传输参数和第一参考信号，第一传输参数为网络设备与第二终端设备之间传输数据所用的传输参数，第一终端设备与第二终端设备为不同的终端设备；根据第一传输参数解调第一参考信号。从而可以提高确定误码率的准确性，从而可以解决基于模型仿真或理论计算误码率在实际高动态性、场景的多样性的无线环境中难以保证准确性的问题。
本申请提出一种通信方法，下面将分别通过如下各实施例进行描述。应理解的是，这些通信方法可以相互结合使用。
本申请实施例(如下述图2-图4对应的实施例)中可以以第一终端设备和网络设备作为交互示意的执行主体为例来示意该方法，但本申请并不限制该交互示意的执行主体。例如，终端设备也可以是支持该第一终端设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分第一终端设备功能的逻辑模块或软件；网络设备也可以是支持该网络设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分网络设备功能的逻辑模块或软件。本申请实施例在这里做统一说明，后续不再赘述。
结合上述的网络架构，下面对本申请实施例提供的一种通信方法进行描述。请参阅图2，图2是本申请实施例提供的一种通信方法的交互示意图。如图2所示，该通信方法可以包括S201-S202。
S201：网络设备向第一终端设备发送第一传输参数和第一参考信号，第一传输参数为网络设备与第二终端设备之间传输数据所使用的传输参数。相应地，第一终端设备接收来自网络设备的第一传输参数和第一参考信号。
第一终端设备和第二终端设备是与网络设备进行通信的不同终端设备。第二终端设备可以理解为网络设备的第一合法用户，第一终端设备可以理解为是网络设备的第二合法用户以及假定是第一合法用户的“EVE”。
网络设备与第二终端设备之间的第一传输参数(即合法链路的物理层传输参数)可以共享给其它终端设备，例如共享给第一终端设备，即网络设备向第一终端设备发送第一传输参数。可选地，网络设备可以在向第二终端设备发送第一传输参数的同时，也向第一终端设备发送该第一传输参数，可以理解地，也可以不限制网络设备向第一终端设备和第二终端设备发送第一传输参数的先后顺序。
其中，第一传输参数可以包括但不限于加扰方式、调制与编码策略(modulation and coding scheme，MCS)、传输时频资源等。
网络设备还可以向第一终端设备发送第一参考信号，其中，第一参考信号承载第一传输信息，第一传输信息根据第一传输参数进行调制。可选地，网络设备可以与第二终端设备协商第一传输信息的具体内容。在后续第一终端设备接收来自网络设备的第一传输信息的过程中，由于第一终端设备已知第一传输参数，可能带来安全性的风险，因此第一传输信息可以是由网络设备与第二终端设备协商的不具备安全风险的明文信息，第一传输信息也可以是网 络设备预先存储的一些特定用于第一终端设备确定PER的信息。
进一步可选地，网络设备在向第一终端设备发送第一传输参数之前，可以先告知第一终端设备，以使第一终端设备能够及时接收到第一传输参数。
S202：第一终端设备根据第一传输参数解调第一参考信号。
第一终端设备接收来自网络设备的第一传输参数和第一参考信号后，可以使用第一传输参数解调第一参考信号得到第一参考信号承载的第一传输信息。第一终端设备可以对原第一传输信息和根据第一传输参数解调第一参考信号得到的第一传输信息进行对比，例如可以采用完整性校验两个第一传输信息的完整性和/或校验两个第一传输信息的差异性等，再根据完整性和/或差异性确定该次根据第一传输参数解调第一参考信号是否成功。
可选地，网络设备可以多次向第一终端设备发送第一参考信号，以使第一终端设备多次根据第一传输参数解调第一参考信号。
本实施例中，网络设备通过向第一终端设备发送第一传输参数，第一传输参数为网络设备与第二终端设备之间传输数据所用的传输参数，第一终端设备与第二终端设备为不同的终端设备，根据第一传输参数解调第一参考信号。网络设备将第二终端设备的传输参数共享发送给第一终端设备，以使第一终端设备能够解调第一参考信号，从而可以得到第一终端设备的PER。可以理解为，以第一终端设备作为第二终端设备的“EVE”，协助统计“EVE”的PER，从而可以提高确定误码率的准确性，从而可以解决基于模型仿真或理论计算误码率在实际高动态性、场景的多样性的无线环境中难以保证准确性的问题。
在图2的基础上，下面对本申请实施例提供的另一种通信方法进行描述。应理解，本申请中不同实施例的术语解释可以互相参考，为避免描述冗余，不同实施例可以不对同一术语赘述。请参阅图3，图3是本申请实施例提供的另一种通信方法的交互示意图。如图3所示，该通信方法可以包括S301-S304。其中，S301可选的步骤。
S301：第一终端设备向网络设备发送请求信息，请求信息用于请求网络设备发送第一传输参数。相应地，网络设备接收来自第一终端设备的请求信息。
第一传输参数可以是第一终端设备向网络设备发送请求信息请求发送的，也可以是网络设备自行向第一终端设备发送的。可选地，若是网络设备自行向第一终端设备发送的，可以在向第一终端设备发送第一传输参数之前，先告知第一终端设备，以使第一终端设备能够及时接收到第一传输参数。
S302：网络设备向第一终端设备发送第一传输参数和第一参考信号，第一传输参数为网络设备与第二终端设备之间传输数据所使用的传输参数。相应地，第一终端设备接收来自网络设备的第一传输参数和第一参考信号。
S303：第一终端设备根据第一传输参数解调第一参考信号。
应理解，步骤S302-步骤S303与步骤S201-步骤S202对应，步骤S302-步骤S303中的相关描述可以参见上述步骤S201-步骤S202的描述，此处为了避免重复，不再赘述。
S304：第一终端设备向网络设备发送PER，该PER根据第一传输参数解调第一参考信号确定。相应地，网络设备接收来自第一终端设备的PER。
可以重复S302和S303的步骤，直到达到一定阈值，第一终端设备可以统计每次解调第一参考信号的结果得到PER，例如根据每次的解调成功与否得到PER，并可以向网络设备上报该PER，以使网络设备确定第一终端设备的PER。可以理解，该阈值可以是网络设备通过无线资源控制(radio resource control，RRC)配置，也可以是协议预定义的，本申请对此不作 限定。
可选地，网络设备确定第一终端设备的PER后，可以停止向第一终端设备发送第一参考信号。
本实施例中，网络设备通过向第一终端设备发送第一传输参数，第一传输参数为网络设备与第二终端设备之间传输数据所用的传输参数，第一终端设备与第二终端设备为不同的终端设备，根据第一传输参数解调第一参考信号。网络设备将第二终端设备的传输参数共享发送给第一终端设备，以使第一终端设备能够解调第一参考信号，从而可以得到第一终端设备的PER。可以理解为，以第一终端设备作为第二终端设备的“EVE”，协助统计“EVE”的PER，从而可以提高确定误码率的准确性，从而可以解决基于模型仿真或理论计算误码率在实际高动态性、场景的多样性的无线环境中难以保证准确性的问题。在此基础上，该实施例可以由第一终端设备确定PER，并向网络设备上报该PER，以使网络设备确定第一终端设备的PER。
在图2的基础上，下面对本申请实施例提供的又一种通信方法进行描述。应理解，本申请中不同实施例的术语解释可以互相参考，为避免描述冗余，不同实施例可以不对同一术语赘述。请参阅图4，图4是本申请实施例提供的又一种通信方法的交互示意图。如图4所示，该通信方法可以包括S401-S405。其中，S401是可选的步骤。
S401：第一终端设备向网络设备发送请求信息，请求信息用于请求网络设备发送第一传输参数。相应地，网络设备接收来自第一终端设备的请求信息。
应理解，步骤S401与步骤S301对应，步骤S401中的相关描述可以参见上述步骤S301的描述，此处为了避免重复，不再赘述。
S402：网络设备向第一终端设备发送第一传输参数和第一参考信号，第一传输参数为网络设备与第二终端设备之间传输数据所使用的传输参数。相应地，第一终端设备接收来自网络设备的第一传输参数和第一参考信号。
S403：第一终端设备根据第一传输参数解调第一参考信号。
应理解，步骤S402-步骤S403与步骤S201-步骤S202对应，步骤S402-步骤S403中的相关描述可以参见上述步骤S201-步骤S202的描述，此处为了避免重复，不再赘述。
S404：第一终端设备向网络设备发送指示信息，指示信息用于指示根据第一传输参数解调第一参考信号是否成功。相应地，网络设备接收来自第一终端设备的指示信息。
可以重复S402和S403的步骤，直到达到一定阈值，第一终端设备可以统计每次解调第一参考信号的结果得到解调成功与否，并可以向网络设备发送用于指示根据第一传输参数解调第一参考信号是否成功的指示信息。可以理解，该阈值可以是网络设备通过RRC配置，也可以是协议预定义的，本申请对此不作限定。
可选地，终端设备可以在每次根据第一传输参数解调第一参考信号之后就向网络设备上报该次解调结果的指示信息，也可以是在达到一定阈值之后，一次性向网络设备上报多次解调结果的指示信息。
S405：网络设备根据指示信息确定第一终端设备的PER。
网络设备接收来自第一终端设备的指示信息后，可以根据指示信息确定第一终端设备的PER。例如，网络设备共向第一终端设备发送了N次第一参考信号，接收来自第一终端设备的指示信息，得到N次解调结果，确定解调成功的次数。根据解调成功的次数和总次数N次，即可得到第一终端设备的PER。其中，N为大于或等于1的正整数。
可选地，网络设备确定第一终端设备的PER后，可以停止向第一终端设备发送第一参考 信号。
本实施例中，本实施例中，网络设备通过向第一终端设备发送第一传输参数，第一传输参数为网络设备与第二终端设备之间传输数据所用的传输参数，第一终端设备与第二终端设备为不同的终端设备，根据第一传输参数解调第一参考信号。网络设备将第二终端设备的传输参数共享发送给第一终端设备，以使第一终端设备能够解调第一参考信号，从而可以得到第一终端设备的PER。可以理解为，以第一终端设备作为第二终端设备的“EVE”，协助统计“EVE”的PER，从而可以提高确定误码率的准确性，从而可以解决基于模型仿真或理论计算误码率在实际高动态性、场景的多样性的无线环境中难以保证准确性的问题。在此基础上，该实施例可以由第一终端设备根据第一传输参数解调第一参考信号后，向网络设备上报解调结果，由网络设备根据解调结果确定PER。
在图2-图4的基础上，下面对本申请实施例提供的又一种通信方法进行描述。应理解，本申请中不同实施例的术语解释可以互相参考，为避免描述冗余，不同实施例可以不对同一术语赘述。请参阅图5，图5是本申请实施例提供的又一种通信方法的交互示意图。图5对应的实施例)中可以以网络设备作为执行主体为例来示意该方法，如图5所示，该通信方法可以包括S501-S503。
S501：网络设备确定所述第二终端设备的第一区域。
网络设备可以确定第二终端设备的位置，并可以以第二终端设备的位置确定第一区域，第一区域可以是距离第二终端设备一定距离的范围。例如，第一区域可以是以第二终端设备为圆心，半径为50m的圆形区域。可以理解地，第一区域可以是受控区域，指的是可以检测的区域，该区域是假定没有“EVE”的。
关于网络设备确定第二终端设备位置的方式可以参考前述相关内容。例如可以使用DL-TDOA、UL-TDOA、DL AoD、UL AoA、RTT、E-CID等定位方法实现网络设备确定第二终端设备的位置，在此不再赘述。
S502：网络设备计算第一区域外的至少一个终端设备的PER。
网络设备确定得到第一区域后，可以计算第一区域外的至少一个终端设备的PER。确定方式可以如图2中所示的具体实现方式，在此不再赘述。
S503：网络设备确定PER最低的终端设备为第一终端设备。
网络设备确定第一区域外的至少一个终端设备的PER后，可以将PER最低的终端设备确定为第一终端设备。可选地，可以将大于某一PER阈值的终端设备确定为第一终端设备，或者也可以将等于某一PER阈值的终端设备确定为第一终端设备，或者还可以将等于某一PER阈值的终端设备确定为第一终端设备。又例如，可以将PER最高的终端设备确定为第一终端设备。本申请对此不作限定。
在一个实施例中，请参阅图6，图6是本申请实施例提供的一种网络设备确定第一终端设备的场景示意图。如图6所示，网络设备根据第二终端设备的位置确定第一区域，该第一区域边缘包括一个或多个终端设备(图6仅示意包括终端设备601、终端设备602、终端设备603和终端设备604)，其中，假定终端设备601的PER＝0.35，终端设备602的PER＝0.2，终端设备603的PER＝0.3，终端设备604的PER＝0.25，在此场景下，网络设备可以选择将PER最低的终端设备602确定为第一终端设备。
由于假定第一终端设备是第二终端设备的“EVE”，因此网络设备确定第一终端设备尤为重要。通过本实施例，可以实现网络设备确定第一终端设备，以第一终端设备作为第二终端 设备的“EVE”，协助统计“EVE”的PER，从而可以提高确定误码率的准确性，从而可以解决基于模型仿真或理论计算误码率在实际高动态性、场景的多样性的无线环境中难以保证准确性的问题。
