Description

通信装置、终端设备及通信方法 技术领域
本申请实施例涉及通信技术，尤其涉及一种通信装置、终端设备及通信方法。
背景技术
新无线(new radio，NR)系统的不同频段(band)中，700MHz的频分双工(frequency division duplexing，FDD)频段支持上下行各45MHz的对称频谱，其中，上行(uplink，UL)频段为703MHz-748MHz，下行(downlink，DL)频段为758MHz-803MHz。可见，用户设备(user equipment，UE)的发射(Tx)频谱(即UL band)与接收(Rx)频谱(即DL band)相隔较近，只有10MHz(748MHz-758MHz)的间隔。双工器中的发射滤波器和接收滤波器很难实现10MHz的频谱抑制需求。
相关技术中，UE采用双双工器解决上述问题。每个双工器的接收滤波器和发射滤波器的带宽均为30MHz，由两个双工器中的接收滤波器的30MHz带宽拼接成45MHz带宽，中间有15MHz的重叠区域，由两个双工器中的发射滤波器的30MHz带宽拼接成45MHz带宽，中间有15MHz的重叠区域。
但是，上述双双工器在一些场景下无法充分利用运营商的频谱资源，存在频谱浪费的问题，而且UE的峰值速率受限。

相关技术中的双双工器中，每个双工器的接收滤波器和发射滤波器的带宽均为30MHz。然而，中国广播电视网络(china broadcasting network，CBN)的频谱分配中可分配的最大下行带宽为40MHz。为了为用户设备提供尽可能高的下行峰值速率，可以将下行频带的带宽配置的尽可能大。而相关技术中使用的双双工器只能支持对称的且最大为30MHz的上下行带宽，而且上行频带的带宽配置的与下行频带的带宽一致。由于用户设备发送的上行信号主要包括信令和少量数据，通常不需要很大的带宽即可完成，而如果分配带宽大小相同的上行带宽和下行带宽，可能会导致上行频谱资源的浪费，或者，下行频谱受双工器限制一次最大只能分配30MHz带宽，又会导致部分下行频谱资源无法被分配，因此降低了频谱资源利用率；另一方面，分配带宽大小相同的上行带宽和下行带宽且带宽较大时，难以满足带外的DTV杂散指标保护要求。
本申请实施例提出了可以在频谱分配上考虑非对称上下行带宽，将上行频谱和下行频谱解耦，例如上行频带的带宽分配30MHz，下行频带的带宽分配40MHz。基于该分配方案，本申请实施例提供了一种通信装置，用于支持上行带宽和下行带宽非对称情况下的收发滤波。
本申请实施例提供了一种通信装置，该通信装置可以应用于上述终端设备的收发器212中。图4为本申请实施例通信装置实施例一的结构示意图，如图4所示，该通信装置可以包括：第一双工器41、第二双工器42和第一切换开关43。其中，第一切换开关43的第一输出端431连接第一双工器41的输入端，第一切换开关43的第二输出端432连接第二双工器42的输入端。当第一切换开关43切换到第一输出端431，第一双工器41所 在支路连通。当第一切换开关43切换到第二输出端432时，第二双工器42所在支路连通。第一双工器41的发射滤波器411对应第一上行频带，第一双工器41的接收滤波器412对应第一下行频带，第一下行频带的带宽大于第一上行频带的带宽。第二双工器42的发射滤波器421对应第二上行频带，第二双工器42的接收滤波器422对应第二下行频带，第二下行频带的带宽大于第二上行频带的带宽。
可选的，上述第一下行频带与第二下行频带的带宽相同。相同可以理解为第一下行频带与第二下行频带的带宽相同，但两个频带的频率位置不同，例如，第一下行频带为758MHz-803MHz，第二下行频带为703MHz-748MHz，该两个频带的带宽均为45MHz，但第二下行频带位于低频位置，第一下行频带位于高频位置。相同也可以理解为第一下行频带与第二下行频带的带宽和位置均相同，例如，第一下行频带和第二下行频带均为758MHz-803MHz，其带宽为45MHz。
优选的，上述第一上行频带可以是指703MHz-733MHz，其带宽为30MHz，第二上行频带可以是指718MHz-748MHz，其带宽为30MHz，第一下行频带和第二下行频带可以是指758MHz-803MHz，其带宽为45MHz。
在一种可能的实现方式中，第一双工器41的接收滤波器412和第二双工器42的接收滤波器422为全带宽滤波器。全带宽可以理解为与通信系统所支持的通信制式匹配的整个下行带宽。
该通信装置中设置有两个双工器，该两个双工器的发射滤波器分别被设置为对应两个不同的上行频带，该两个双工器的接收滤波器分别被设置为对应两个下行频带，而在同一个双工器中，接收滤波器对应的下行频带大于发射滤波器的对应的上行频带，因此，无论切换开关将两个双工器中的哪个双工器所在的支路连通，都可以实现上行带宽和下行带宽非对称情况下的收发滤波，例如700MHz频段(n28)的上下行非对称带宽。这样，应用发明实施例提供的通信装置，下行带宽不受上行带宽的大小限制，在下行带宽大于上行带宽的场景下，可以充分利用下行带宽的频谱资源，从而提高了频谱资源利用率。另外，本发明实施例提供的双双工器中的每个双工器中较大的下行频带可以为用户设备提供更高的下行峰值速率，而较小的上行频带，可以确保能够满足带外的数字电视DTV杂散指标保护要求。
在图4所示通信装置的基础上，图5为本申请实施例通信装置实施例二的结构示意图，如图5所示，该通信装置还可以包括：功率放大器(power amplifier，PA)51、第二切换开关52和天线53。其中，PA 51的输出端连接第一切换开关43的输入端。第一双工器41的输出端连接第二切换开关52的第一输入端521，第二双工器42的输出端连接第二切换开关52的第二输入端522。第二切换开关52的输出端连接天线53。
该通信装置由PA 51对信号进行功率放大后输送至第一双工器41或第二双工器42，再配合第二切换开关52，将信号输送至天线53。第一切换开关43切换到的第一输出端431且第二切换开关52切换到的第一输入端521，第一双工器41所在的支路连通，第一切换开关43切换到的第二输出端432且第二切换开关52切换到的第二输入端522，第二双工器42所在的支路连通。
在图4所示通信装置的基础上，图6为本申请实施例通信装置实施例三的结构示意图，如图6所示，该通信装置还可以包括：第一天线61和第二天线62。其中，第一双工器41 的输出端连接第一天线61，第二双工器42的输出端连接第二天线62。
该通信装置第一双工器41和第一天线61位于同一支路，实现一路信号的发送和接收，第二双工器42和第二天线62位于同一支路，实现另一路信号的发送和接收。
本申请实施例提供了一种应用上述任一装置实施例中的通信装置的通信方法，该通信方法可以由包括上述通信装置的终端设备执行。图7为本申请实施例通信方法实施例的流程图，如图7所示，本实施例的通信方法可以包括：
步骤701、接收载波配置信息。
上述载波配置信息包括为终端设备配置的载波的带宽和/或频点；当载波配置信息对应于第一上行频带，通信装置中的第一切换开关切换到第一输出端；当载波配置信息对应于第二上行频带，通信装置中的第一切换开关切换到第二输出端。
接入网设备为终端设备配置载波，然后通过下行信号将载波配置信息发送给终端设备。如上所述，通信装置中的两个双工器中的接收滤波器分别对应第一下行频带和第二下行频带，可以是二者带宽相同位置不同，或者可以是二者带宽和位置均相同，或者二者的带宽均为全带宽。且接收滤波器对应的下行频带大于同一双工器中发射滤波器对应的上行频带。因此终端设备在确定第一切换开关的状态时，重点关注载波配置信息中的上行载波的配置信息。
在一种可能的实现方式中，当终端设备接收到的载波配置信息是载波的带宽时，终端设备重点关注上行载波的带宽属于两个双工器中哪一个的发射滤波器所支持的频带。例如，上行载波的带宽为703MHz-733MHz，此时上行载波的带宽对应于第一上行频带，终端设备将通信装置中的第一切换开关切换到第一输出端；上行载波的带宽为718MHz-748MHz，此时上行载波的带宽对应于第二上行频带，终端设备将通信装置中的第一切换开关切换到第二输出端。
在一种可能的实现方式中，当终端设备接收到的载波配置信息是载波的频点时，终端设备重点关注上行载波的频点属于两个双工器中哪一个的发射滤波器所支持的频带。例如，上行载波的频点为718MHz，此时上行载波的频点对应于第一上行频带，终端设备将通信装置中的第一切换开关切换到第一输出端；上行载波的频点为733MHz，此时上行载波的频点对应于第二上行频带，终端设备将通信装置中的第一切换开关切换到第二输出端。
在一种可能的实现方式中，当终端设备接收到的载波配置信息是载波的带宽和频点时，终端设备重点关注上行载波的带宽和频点属于两个双工器中哪一个的发射滤波器所支持的频带。可参照上述说明，此处不再赘述。
优选的，终端设备在配置双工器中的发射滤波器和接收滤波器的频带时，发射滤波器对应的上行频带的上行载波和接收滤波器对应的下行频带的下行载波需要遵循约束关系。即上行载波的带宽在下行映射载波带宽内，下行映射载波带宽是根据第一下行频带或第二下行频带以及默认收发频率间隔得到。
图8示例性的示出了一种载波配置示意图，如图8所示，假设终端设备将通信装置中的第一切换开关切换到第一输出端，此时终端设备可以支持的上行载波的最大带宽为703MHz-733MHz，下行载波的最大带宽为758MHz-803MHz。
当配置下行载波的带宽为763MHz-803MHz(共40MHZ)时，下行映射载波带宽为 708MHZ-748MHz，由于需要满足上行载波的带宽在下行映射载波带宽内，因此终端设备配置上行载波的带宽为708MHz-733MHz(共25MHz)。
当配置下行载波的带宽为758MHz-798MHz(共40MHz)时，下行映射载波带宽为703MHZ-743MHz，由于需要满足上行载波的带宽在下行映射载波带宽内，因此终端设备配置上行载波的带宽为703MHz-733MHz(共30MHz)。
图9示例性的示出了另一种载波配置示意图，如图9所示，假设终端设备将通信装置中的第一切换开关切换到第二输出端，此时终端设备可以支持的上行载波的最大带宽为718MHz-748MHz，下行载波的最大带宽为758MHz-803MHz。
当配置下行载波的带宽为763MHz-803MHz(共40MHz)时，下行映射载波带宽为708MHz-748MHz，由于需要满足上行载波的带宽在下行映射载波带宽内，因此终端设备配置上行载波的带宽为718MHz-748MHz(共30MHz)。
当配置下行载波的带宽为758MHz-798MHz(共40MHz)时，下行映射载波带宽为703MHz-743MHz，由于需要满足上行载波的带宽在下行映射载波带宽内，因此终端设备配置上行载波的带宽为718MHz-743MHz(共25MHz)。
步骤702、接收调度信息。
调度信息指示上行资源，当通信装置中的第一切换开关切换到第一输出端，上行资源的带宽小于第一上行频带的带宽，当通信装置中的第一切换开关切换到第二输出端，上行资源的带宽小于第二上行频带的带宽。接入网设备配置给终端设备的上行资源，其最大带宽不能大于所在支路连通的双工器的发射滤波器所对应的上行频带的带宽，即第一双工器所在的支路连通时，上行资源的带宽小于第一上行频带的带宽，第二双工器所在的支路连通时，上行资源的带宽小于第二上行频带的带宽。
终端设备可以采用以下两种方法确保上下行传输性能：
一、优先保证上行传输性能
第一下行频带与第二下行频带相同。相同可以理解为第一下行频带和第二下行频带的带宽和位置都一样，例如，第一下行频带和第二下行频带均为758MHz-803MHz。第一下行频带包括多个子频带，多个子频带中的每个子频带对应至少一个灵敏度指标。接入网设备为终端设备配置的载波的带宽和/或频点对应多个子频带中的一个子频带。此时终端设备根据其子频带对应的至少一个灵敏度指标，确定通信装置的灵敏度指标。优选的，可以将配置的下行载波的带宽分成多个子频带，每个子频带定义至少一个灵敏度指标，终端设备将多个子频带中靠近上行载波者，其灵敏度指标做一定程度的放松。
二、优先保证下行传输性能
(1)终端设备可以限制发送上行数据的资源块(resource block，RB)数量。如果终端设备最大可以采用50个RB发送上行数据，通过RB数量限制，终端设备即使被分配了50个RB，在实际发送上行数据时，仍需要减少该RB数量，例如最多只能采用45个RB发送上行数据。优选的，当终端设备将第一切换开关切换到第二输出端时，终端设备才需要限制发送上行数据的RB数量。上述RB数量为示例性说明，本申请实施例并不限定RB数量和RB数量的减少量。
(2)终端设备可以限制发送上行数据的最大发射功率。如果终端设备的最大发射功率可以是23dB，但是考虑到干扰、相邻频带的保护，终端设备只能发到20dB。优选的， 当终端设备将第一切换开关切换到第二输出端时，终端设备才需要限制发送上行数据的最大发射功率。上述发射功率为示例性说明，本申请实施例并不限定发射功率和发射功率的回退数量。
步骤703、在上行资源上发送信号。
本实施例，针对上述通信装置，终端设备在接入网设备配置的载波、上行资源的基础上，配置通信装置中的两个双工器所在支路的连通状态和载波带宽，以及上下行传输的相关参数，确保上行带宽和下行带宽非对称情况下的上下行传输性能。这样，应用上述图4-6任一所示的通信装置，下行带宽不受上行带宽的大小限制，在下行带宽大于上行带宽的场景下，可以充分利用下行带宽的频谱资源，从而提高了频谱资源利用率。另外，基于双双工器中的每个双工器中较大的下行频带可以为用户设备提供更高的下行峰值速率，而较小的上行频带，可以确保能够满足带外的DTV杂散指标保护要求。
在实现过程中，上述方法实施例的各步骤可以通过处理器中的硬件的集成逻辑电路或者软件形式的指令完成。处理器可以是通用处理器、数字信号处理器(digital signal processor,DSP)、特定应用集成电路(application-specific integrated circuit，ASIC)、现场可编程门阵列(field programmable gate array,FPGA)或其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。本申请实施例公开的方法的步骤可以直接体现为硬件编码处理器执行完成，或者用编码处理器中的硬件及软件模块组合执行完成。软件模块可以位于随机存储器，闪存、只读存储器，可编程只读存储器或者电可擦写可编程存储器、寄存器等本领域成熟的存储介质中。该存储介质位于存储器，处理器读取存储器中的信息，结合其硬件完成上述方法的步骤。
