具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、第五代(5th generation，5G)系统或新无线(new radio，NR)或者其他演进的通信系统等。
本申请实施例中的终端设备也可以称为：用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、接入终端、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等。
终端设备可以是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、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、个人数字助理(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，5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，在本申请实施例中，终端设备还可以是物联网(internet of things，IoT)系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。
随着移动通信的发展，出现了大量对上行数据的传输速率、上行数据的传输时延等的要求越来越高的场景。例如，手机直播、电视台高清视频直播、新媒体直播、摄像头监控视频，或工厂生产线数据实时上传等应用，这些应用都通过移动通信将数据进行实时上传。
当前，长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)系统或新无线(New radio，NR)或者其他演进的通信系统存在频分双工(frequency division  duplex,FDD)和时分双工(time division duplex,TDD)两种制式。
图1是适用于本申请实施例的FDD制式的一示意图。如图1所示，在FDD制式的场景下，上行传输与下行传输在两个独立的对称频率的信道上进行，通过频段以区分接收信道与发送信道，可以同时进行上行传输与下行传输。
由于一些因素的影响，例如，受限于终端设备的设计尺寸，在1GHz以下的低频段需要共用同一根天线，对于FDD的频段，采用双工器实现不同频率的接收和发送。图2是适用于本申请实施例的1GHz以下的工作频段的频谱分布的一示意图。如图2所示，每一个工作频段包括一个上行(transmitter,TX)频谱与一个下行(receiver,RX)频谱，并且不同工作频段包含的上行频谱与下行频谱可能存在频率范围重叠的现象。例如，800工作频段的800RX与900工作频段的900TX(单位：MHz)出现了频率范围重叠的现象。所以，通常需要通过开关实现不同频谱的切换。图3为FDD低频的通信架构的一示意图。如图3所示，该通信框架由共用功率放大器(power amplifier,PA)、单刀三掷开关、3个对应不同工作频段的双工器、共用天线，以及共用低噪声放大器(low noise amplifier,LNA)构成，其中，每个双工器由对应包含上行频谱与下行频谱的工作频段的滤波器组成。在通信的过程中，可以通过单刀三掷开关实现不同工作频段的切换。图4为FDD中高频的通信架构的一示意图。如图4所示，在中高频段的通信架构中，由于频段间的频率间隔比较大，可以实现由对应不同工作频段的滤波器组成双工器。
然而，在香农公式中，即，
Figure PCTCN2022098788-appb-000001
C表示该信道的信道容量，B表示信道带宽，S为信号功率，N为噪声功率。可以得到，在通信系统中，更宽的带宽可以带来更大的信道容量，从而提供更好的上/下行通信体验。
在中高频的通信系统中，可以通过载波聚合(carrier aggregation,CA)技术，如图4所示，可以实现1800RX+2100RX+2600RX的大带宽，从而提高信道容量。
然而，在1GHz以下的低频通信链路中，通常三个工作频段之间的链路只能单独工作，导致载波聚合技术较难实现，信道容量会受限于信道带宽。
鉴于此，本申请提供一种传输信号的装置与方法，可以实现包括1GHz及以下的频段的多频信号的同时接收和/或发送，提升包括1GHz及以下的频段的信道带宽，从而改善上行和/或下行的宽带容量，提高通信性能；进一步地，也可以保持原有的低频通信架构，在某一些工作场景下，终端设备在同一时刻只工作在一个工作频段，达到低能耗、低损耗的效果。
应理解，在本申请实施例提供的传输信号的装置中，可以应用于包括1GHz以下的工作频段，例如，在第三代合作伙伴计划(3rd generation partnership project,3GPP)规定的NR频段中，包括703MHz-748MHz上行频谱，以及758MHz-803MHz下行频谱的第28工作频段；824MHz-849MHz上行频谱，以及869MHz-894MHz的第5工作频段；880MHz-915MHz上行频谱，以及925MHz-960MHz的第8工作频段；1427MHz-1470MHz上行频谱，以及1475MHz-1518MHz的第74工作频段，以及规定的其他工作频段。

作为另一种设计，m个工作频段包括m个下行频谱。作为示例，第一双工器可以包括第一接收双工器，该第一接收双工器包括对应1805-1880 RX频谱、869-894 RX频谱，与925-960 RX频谱(单位：MHz)的三个下行频谱的三个工作频段(即，第3、5、8工作频段)的滤波器。
作为另一种设计，m个工作频段包括z 1个上行频谱与z 2个下行频谱，z 1+z 2∈[m，2m]，且z 1与z 2为正整数。作为示例，第一双工器可以包括第一收发双工器，该第一收发双工器包括对应880-915 TX频谱、925-960 RX频谱、703-748 TX频谱与758-803 RX频谱(单位：MHz)的两个上行频谱与两个下行频谱，共两个工作频段(即，第8、28工作频段)的滤波器。
此外，第一双工器与第一开关相连，作为一种设计，第一开关包括第一发送开关，第一发送开关与第一发送双工器相连，用于通过第一发送双工器与第一发送开关发送来自通信模块的信号。从而，通过第一发送双工器与第一发送开关相连，可以完成上行传输的业务需求，从而实现包括低频的多频信号的同时发送，提升信道带宽，改善通道的质量，满足上行的大容量需求。其中，通信模块可以包括共用的功率放大器。
作为另一种设计，第一开关包括第一接收开关，第一接收开关与第一接收双工器相连，用于通过第一接收双工器与第一接收开关接收来自通信模块的信号。从而，可以实现包括低频的多频信号的同时接收，提升信道带宽，改善通道的质量，满足下行的大容量需求。其中，通信模块可以包括共用的天线。
作为另一种设计，第一开关包括第一发送开关与第一接收开关，第一发送开关与第一接收开关均与第一收发双工器相连，用于通过第一发送开关、第一收发双工器与第一接收开关收发来自通信模块的信号。从而，可以完成上/下行传输的业务需求，实现包括低频的多频信号的同时接收与发送，提升信道带宽，改善通道的质量，满足上行与下行的大容量需求。其中，通信模块可以包括共用的功率放大器与共用的天线。
进一步地，传输信号的装置500还包括第一控制模块，用于根据业务的需求，控制第一开关与第一双工器相连。其中，业务的需求包括上行传输(发送信号)的需求、下行传输(接收信号)的需求，以及上行与下行同时传输(收发信号)的需求。
作为一种设计，在发送来自通信模块的信号的情况下，控制第一发送开关与第一发送双工器相连。其中，通信模块可以包括共用的功率放大器。
作为另一种设计，在接收来自通信模块的信号的情况下，控制第一接收开关与第一接收双工器相连。其中，通信模块可以包括共用的天线。
作为另一种设计，在收发来自通信模块天线与功率放大器的信号的情况下，控制第一 发送开关和第一接收开关均与第一收发双工器相连。其中，通信模块可以包括共用的功率放大器与共用的天线。
从而，可以根据业务的需求，控制上述第一开关与第一双工器的连接。例如，在上行传输的业务需求中，控制第一发送双工器与第一发送开关相连，从而可以获得较大的信道容量，实现包括低频的多频信号的同时发送；或者，在下行传输的业务需求中，控制第一接收双工器与第一接收开关相连，从而可以获得较大的信道容量，实现包括低频的多频信号的同时接收；或者，在上行传输与下行传输同时进行的业务需求中，控制第一收发双工器与第一发送开关、第一接收开关相连，从而提升瞬时的容量带宽，满足上行与下行的大容量需求，实现包括低频的多频信号的同时接收与发送。

在上行传输的场景中，共用的功率放大器为多频发射的工作模式，第一开关与第一发送双工器连接，从而可以获取上行传输的大带宽，提升上行传输的发送能力。
在下行传输的场景中，通过共用的天线接收信号之后，第一开关与第一接收双工器连接，用于通过该第一双工器将信号传输至独立LNA。从而，可以实现包括低频的多频信号的同时接收，提升信道带宽，以及下行传输的接收能力。
进一步地，该传输信号的装置500还包括第一控制模块，该第一控制模块用于根据业务的需求，控制第一开关与第一个发送双工器相连，或控制第一开关与第一接收双工器相连。
举例而言，通过传输信号的装置500的信号为上行传输的业务需求，则第一控制模块控制第一开关与第一发送双工器连接。通过传输信号的装置500的信号为下行传输的业务需求，则第一控制模块控制第一开关与第一接收双工器连接。
