Description

一种通信装置及通信方法
本申请要求于2021年12月30日提交中国国家知识产权局、申请号为202111656952.5、申请名称为“一种通信装置及通信方法”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
本申请实施例涉及无线通信领域，尤其涉及一种通信装置及通信方法。
背景技术
频分双工(frequency division duplexing，FDD)是一种常用的无线通信技术，其原理是：上行链路(示例性的，终端设备到基站)和下行链路(示例性的，基站到终端设备)采用两个分开的频率信道(有一定频率间隔要求)工作，且工作在对称频带上；也即是说，在FDD模式中，通信设备在两个分离的、对称的频率信道上分别进行接收和发送。FDD的这种通信特性，使得FDD在功率控制、链路自适应、信道和干扰反馈等方面具有天然的优势。
但也由于FDD的通信特性，使得上行频段只能用于单一的发送，下行频段只能用于单一的接收。在终端设备和基站构成的FDD通信***中，对频谱资源的要求较高。鉴于此，本领域技术人员提出了FDD全双工的概念，可以理解为：在FDD的上行频段能够同时接收和发射通信信号，在FDD的下行频段也能够同时接收和发射通信信号。FDD全双工的通信模式将引入上行信号和下行信号之间的干扰。对于基站而言，可以通过改进自身的硬件架构和天线阵列的方式来实现上行信号和下行信号的自干扰消除，而对于终端设备而言，由于硬件体积和天线数量的限制，很难通过与基站类似的方式消除上行信号和下行信号之间的干扰。如何使得终端设备匹配基站FDD全双工的通信需求，是本领域技术人员亟待解决的问题。

接下来，对本申请实施例涉及到的一些概念进行介绍。
1.频分双工(frequency division duplexing，FDD)
FDD是一种常用的无线通信技术，其原理是：上行链路(示例性的，终端设备到基站)和下行链路(示例性的，基站到终端设备)采用两个分开的频率信道(有一定频率间隔要求)工作，且工作在对称频带上；也即是说，在FDD模式中，通信设备在两个分离的、对称的频率信道上分别进行接收和发送(或者称为发射)。FDD的这种通信特性，使得FDD在功率控制、链路自适应、信道和干扰反馈等方面具有天然的优势。但也由于FDD的通信特性，使得上行频段只能用于单一的发送，下行频段只能用于单一的接收。
2.时分双工(time division duplexing，TDD)
TDD是一种通信***的双工方式，在移动通信***中用于分离接收与发射信道(或称为上下行链路)。TDD模式的移动通信***中接收和发射(或称为发送)是在同一频率信道，即载波的不同时隙，用保证时间来分离接收与发射信道。换而言之，在TDD模式中，上行链路和下行链路中信息的传输可以在同一载波频率上进行，即上行链路中信息的传输和下行链路中信息的传输是在同一载波上，通过时分的方式来实现的。由于TDD的这种通信特性，可以在频谱分配不对称的情况下，高效灵活地利用所有可用带宽。另外，针对多媒体应用时上下行链路传输容量的要求不同，采用TDD模式可动态分配上下行链路的容量，实现资源分配的灵活性。并且，由于上下行链路使用相同的频率，上下行链路的一致性较好。在对移动台的发射功率进行控制时，可以用开环功率控制来取代较为复杂的闭环功率控制。
3.双工器(duplexer)
双工器，一般是一个三端口器件，可以理解为一个比较特殊的双向三端滤波器。对于双工器而言，可以将微弱的接收信号耦合进来，又可以将较大功率的发射信号馈送到天线上去；并且双工器可以将发射信号和接收信号相隔离，保证通信装置能同时正常接收和发射通信信号。双工器可以等效理解为两个不同频率的带通滤波器，它可以避免本机的发射信号传输到接收机。在本申请实施例中，双工器可以用于分离不同频段的两个通信信号，让该两个通信信号彼此隔离，避免相互的干扰。
4.滤波器(filter)
滤波器主要是一种选频装置，可以使信号中特定的频率成分通过，而极大地衰减信号中的其他频率成分。换而言之，滤波器可以对通信信号中特定频段或该特定频段以外的通信信号进行有效滤除，可以得到特定频段的通信信号，或滤除特定频段后的通信信号。在本申请实施例中，滤波器可以用于通过两个不同频段的通信信号，衰减通信信号中除该两个频段的其他频率成分。
在一种可能的方式中，FDD的通信模式对频段的使用进行了限制，上行频段只能用于单一的发送，下行频段只能用于单一的接收。在终端设备和基站构成的FDD通信***中，对频谱资源的要求较高。鉴于此，本领域技术人员提出了FDD全双工的概念，可以理解为：在FDD的上行频段能够同时接收和发射通信信号，在FDD的下行频段也能够同时接收和发射通信信号。FDD全双工的通信模式将引入上行信号和下行信号之间的干扰。对于基站而言，可以通过改进自身的硬件架构和天线阵列的方式来实现上行信号和下行信号的自干扰消除，而对于终端设备而言，由于硬件体积和天线数量的限制，很难通过与基站类似的方式消除上行信号和下行信号之间的干扰。鉴于此，提出了本申请实施例的方案。
参见图2，是本申请实施例提供的一种通信装置的结构示意图。图2所示的通信装置可以应用于图1所示的通信***中，示例性的，该通信装置可以为图1中所示的终端设备，在另一示例中，该通信装置还可以为收发装置，该收发装置可以配置在图1中的终端设备上，用于向网络设备发送通信信号，或者接收来自该网络设备的通信信号。该通信装置包括发射模块、接收模块、第一双工器、开关模块。具体的，该发射模块与该开关模块连接，该接收模块与该开关模块连接，该第一双工器与该开关模块连接。

接收模块用于接收通信信号，示例性的，该接收模块可以为低噪声放大器(low noise amplifier，LNA)，它可以放大微弱的接收信号，而且不会引入较大的噪声。该接收模块具备第一频段和第二频段的宽带放大能力。需要说明的是，该LNA作为接收模块仅为示例，该接收模块还可以为具有信号发射能力的其他装置，该装置还可以具备其他功能。可选的，该发射模块和接收模块可以集成在同一个模块中，该模块具备信号的发射和接收的功能。可选的，该发射模块和该接收模块可以共用部分器件，这部分器件具备信号的发射和接收的功能。

其中，第一频段和第二频段不重叠。举例而言，该第一频段可以为n1中的上行工作频段，即1920MHz-1980MHz；第二频段可以为n1中的下行工作频段，即2110MHz-2170MHz。或者，第一频段可以为n1中的下行工作频段，第二频段可以为n1中的上行工作频段。或者，第一频段可以为n3中的上行工作频段，第二频段可以为n3中的下行工作频段。需要说明的是，上述内容中以第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)Release 16(R16)协议中划分的频段为依据，介绍了第一频段和第二频段的一种可能的取值方式。在不同的***和不同的场景中，频段的划分可能会采取不同的方式，另外，随着 无线通信的演进，可能会采用新的频段划分方式；基于不同的频段划分方式，第一频段和第二频段的取值方式可以不同，本申请实施例对此不做限定。

其中，该第一开关模块可以为双刀三掷的开关，第二开关模块可以为单刀双掷的开关。该发射模块与该第一开关模块连接，该接收模块与该第一开关模块连接，该第一双工器(具体为第一端口和第二端口)与该第一开关模块连接，该第一滤波器(具体为第四端口)与该第一开关模块连接；该第一双工器(具体为第三端口)与该第二开关模块连接，该第一滤波器(具体为第五端口)与该第二开关模块连接，该天线与该第二开关模块连接。
以下对各个连接模式的连接情况进行说明：
处于该第一连接模式时，该第一开关模块控制该发射模块与该第一双工器的第一端口连接，且控制该接收模块与该第一双工器的第二端口连接；该第二开关模块控制该第一双工器的第三端口与天线连接。通过这种连接模式，发射信号可以从第一双工器的第三端口发送至天线，再通过天线向外部设备发射出去。接收信号可以通过天线进行接收，再输入到第一双工器的第三端口。
处于该第二连接模式时，该第一开关模块控制该发射模块与该第一双工器的第二端口连接，且控制该接收模块与该第一双工器的第一端口连接；该第二开关模块控制该第一双工器的第三端口与天线连接。通过这种连接模式，发射信号可以从第一双工器的第三端口发送至天线，再通过天线向外部设备发射出去。接收信号可以通过天线进行接收，再输入到第一双工器的第三端口。

在多个终端设备和网络设备构成的通信***中，处于发射状态的终端设备周围的一段距离外的终端设备如果处于接收状态，则不会受到终端设备的发射机的干扰，进而避免了干扰会引起的接收机的灵敏度恶化的问题。基于此，网络设备可以考虑基于位置信息来对进行配对，以实现网络设备自身的全双工模式。如果本申请实施例中的发射模块可以为高线性发射机，这样可以提升发射模块的频谱模板的性能，使得基站可以不需要基于位置信息对终端设备进行配对。为了实现高线性发射机的目的，该通信装置中可以采用数字预失真(digital predistortion，DPD)，LINC-异相恒包络PA，数字发射机等方案。

可选的，该反馈通路的工作频段的中心频率为该发射信号的频段的中心频率。例如，该发射信号为第一频段，则该反馈通路的工作频段的中心频率为该第一频段的中心频率；该发射信号为第二频段，则该反馈通路的工作频段的中心频率为该第二频段的中心频率；该发射信号为第一频段和第二频段，则该反馈通路的工作频段的中心频率为该第一频段的中心频率和第二频段的中心频率。
可选的，该反馈通路的工作频段包含该发射信号的频段。示例性的，该反馈通路的工作频段的带宽可以为该发射信号的频段的带宽的三倍，或者其他倍数值。参见图10，是本申请实施例提供的一种反馈通路的工作频段的示意图。在图10中，第一频段为接收信号的频段，第二频段为发射信号的频段，该反馈通路的工作频段的中心频率为该第二频段的 中心频率，该反馈通路的工作频段的带宽为该发射信号的频段的带宽的三倍。
考虑到接收模块(示例性的，为LNA)同时接收两个频段的接收信号可能会出现性能恶化的问题，在一些实施例中，可以将接收模块分为两个接收子模块，这两个接收子模块共同实现对接收信号的接收。通过这种方式，可以提升通信装置的信号接收能力。示例性的，该接收模块包括第一接收模块和第二接收模块，该第一接收模块用于接收该第一频段的接收信号，该第二接收模块用于接收该第二频段的接收信号。以图8所示的通信装置为基础，进行示例性说明。参见图11，是本申请实施例提供的又一种通信装置的示意图。该第一接收模块和第二接收模块均与第一开关模块进行连接。图11中与图8中相同的模块结构、连接模式可以参照上述图8的实施例内容中的介绍，此处不再赘述。
