技术领域

可选的，图1所示的基站可以是5G基站。
当图1所示的基站是4.5G基站或者5G基站时，第二通信装置12可以为负责集中式无线资源和连接管理控制的CU(centralized unit，集中式单元)，第一通信装置11可以为实现分布式用户面处理功能的DU(distributed unit，分布式单元)。
当图1所示的基站是4.5G基站或者5G基站时，可以重新定义第一通信装置11和第二通信装置12的功能，例如将部分第二通信装置12的处理功能移至第一通信装置11，重构后第二通信装置12可以称为RCC(radio cloud center，无线云中心)，第一通信装置11可以称为RRS(Radio Remote System，射频拉远系统)。
其中图2示出一种第一通信装置11以及第二通信装置12的功能切分方式，该切分方式可以记为option.7-2a。参照图2所示，下面以上行方向(即数据从第一通信装置11到第二通信装置12的传输方向)为例进行介绍：
第一通信装置11包括：射频RF(radio frequency)模块、时频转换模块(通常为快速傅里叶变换FFT(fast fourier transformation)模块)、以及数字波束赋形BF(digital beamforming)模块；其中，RF模块，用于将接收自天线的射频信号(模拟信号)进行模数转换，转换为时域的数字信号；时频转换模块，用于将时域的数字信号进行时频转换，生成频域的数字信号，例如采用FFT算法进行时频转换，在一种方案中进行时频转换之前还可以去除循环前缀(cyclic prefix removal，简称CP removal)，这样时频转换模块可以包括用作视频转换的FFT模块和去循环前缀的CP removal模块；数字BF模块，用于将对频域的数字信号进行波束赋形，生成波束域的数字信号。其中图2中只是示出了一种第一通信装置11的实现方式，通常，时频转换模块与数字BF模块还可以交换一下位置，即，首先由数字BF模块将时域的数字信号进行波束赋形，生成波束域的时域数字信号；再由时频转换模块对于波束域的频域数字信号进行频时转换，生成波束域的频域数字信号。
第二通信装置12包括：解映射(RE de-mapping)模块、信道估计(channel estimation)模块、均衡(equalization)模块、频时转换模块(通常为离散傅里叶逆变换IDFT(inverse discrete fourier transform)模块)、解调(demodulation)模块、比特级处理(bit-level processing)模块、以及介质访问控制MAC(media access control)实体；其中，解映射模块，用于对第一通信装置11输出的波束域的数字信号进行解映射；信道估计模块用于将对解映射模块输出的信号进行信道估计；均衡模块用于对信道估计模块输出的信号进行均衡处理，通过将多个不同波束的用户信号合路，使得均衡处理后的信号为频域的用户层信号；频时转换模块，用于将均衡模块输出的信号进行频时转换，生成的信号为时域的用户层信号；解调模块，用于对频时转换模块输出的信号进行解星座映射处理；比特级处理模块，用于对解调模块输出的信号进行去扰码(de-screambling)、速率匹配(rate de-matching)、解码(de-coding)等处理后生成用户的比特数据流， 其中比特级处理模块还可以实现其他比特级的处理功能，当然，去扰码、速率匹配、解码等处理可以集中在比特级处理模块中实现，也可以以单独的功能模块实现；MAC实体，用于将比特级处理模块输出的比特数据流提交至高层MAC处理。
在图2的基础上，可以将第一通信装置11以及第二通信装置12的功能重新定义时，可以将第二通信装置12的信道估计模块、均衡模块移至第一通信装置11，如图3所示，该切分方式可以记为option.7-new，option.7-new下第一通信装置11的各个单元和第二通信装置12的各个单元的描述可以参考图2中option.7-2a的相关描述。
还可以包括其他切分方式，诸如将信道估计模块、均衡模块、频时转换模块移至第一通信装置11；将信道估计模块、均衡模块、频时转换模块、解调模块移至第一通信装置11；将信道估计模块、均衡模块、频时转换模块、解调模块、比特级处理模块移至第一通信装置11等，或者将第一通信装置11的时频转换模块以及数字波束赋形模块移至第二通信装置12等，以上只是列举的部分示例，可以理解的是在一些方案中也可以在相邻的模块之间添加其他功能模块，或者在实际使用中去除部分功能模块，例如在一些方案中可以取消数字波束赋形BF模块，在本申请的实施例中不再一一列举。
此外，在另一种方案中，以上行方向(即数据从第一通信装置11到第二通信装置12的传输方向)为例，第一通信装置11和第二通信装置12对天馈系统13接收到的射频信号依次执行以下功能模块的处理，模数转换(analog to digital)模块，时频转换模块(可以包含FFT模块以及CP removal模块，具体功能参照上述描述不再赘述)，解映射(RE de-mapping)模块，信道估计(channel estimation)模块或者滤波(prefilering)模块(在上行方向可以选择信道估计模块和滤波模块之一对数据进行信道估计)，均衡(equalization)模块，频时转换模块(通常为离散傅里叶逆变换IDFT(inverse discrete fourier transform)模块)，解调(demodulation)模块，去扰码(de-screambling)模块，速率匹配(rate de-matching)模块，解码(de-coding)模块，以及介质访问控制MAC(media access control)实体。在NR(new radio，新空口)/5G方案中，与LTE方案的区别为上行方向的数据无需进行频时转换模块的处理。其中，去扰码模块用于对解调模块输出的信号进行去扰码处理，速率匹配模块用于对去扰码模块输出的信号进行速率匹配处理，解码模块用于对速率匹配模块输出的信号进行解码处理。其他各模块的功能参考上述示例的描述，此处不再赘述。通常若将第一通信装置11与第二通信装置12的功能在解映射(RE de-mapping)模块之前切分，则该切分方式通常记为option.7-1；若将第一通信装置11与第二通信装置12的功能在均衡(equalization)和频时转换模块之前切分，则该切分方式通常记为option.7-2；若将第一通信装置11与第二通信装置12的功能在去扰码模块之前切分，则该切分方式通常记为option.7-3；若将第一通信装置11与第二通信装置12的功能在MAC实体之前切分，则该切分方式通常记为option.7-6；以上只是列举的部分示例，可以理解的是在一些方案中也可以在相邻的模块之间添加其他功能模块，或者在实际使用中去除部分功能模块，在本申请的实施例中不再一一列举。
通常在，在确定第一通信装置11与第二通信装置12的功能切分方式后，对于第一通信装置11获取的信号，便采用某种固定的功能切分方式进行数据传输。但是，不 同的功能切分方式，CPRI接口的位置不同，由于CPRI接口的带宽通常固定，CPRI接口的位置不同时其能提供的传输带宽会对第一通信装置11与第二通信装置12之间的数据传输造成限制，此外，第一通信装置11的功能模块过多时，会造成第一通信装置11处理复杂度大幅提升。例如，采用option.7-2a切分方式，第一通信装置11与第二通信装置12之间CPRI接口上传输的数据流量与天线数相关，在Massive MIMO(massive multiple-input multiple-output，大规模多数输入多输出)系统大带宽情况下，如64TR(64射频天线)x 100M带宽，第一通信装置11将天线域的数据流降维到波束域的频域数据流传输给第二通信装置12。CPRI接口流量达到100Gbps。在CPRI接口典型的25G传输带宽下，仅可以支持16波束传输，CPRI接口的传输带宽限制解调波束数无法提升，上行多流等情况下回损失性能。而采用option.7-new切分方式，或者功能切分点在IDFT之后的其他切分方式，第一通信装置11与第二通信装置12之间CPRI接口上传输的数据流量与资源块RB(resource block)配对的解调层数(即每个RB承载的用户数据流数)相关，一般的解调层数远小于天线数以及波束数，因此，可以大幅降低第一通信装置11与第二通信装置12之间传输的数据流量，从而支持更多天线以及波束数的解调。但由于信道估计和均衡等功能的大量算法都在第一通信装置11完成，第一通信装置11处理复杂度大幅提升，在第一通信装置11功耗和体积约束下，无法有效提升解调的天线以及波束数。
因此，本申请提供了一种能够实现第一通信装置与第二通信装置采用多种功能切分方式进行数据传输的方法，能够兼顾第一通信装置11处理复杂度的同时降低了CPRI接口的传输带宽对解调的天线以及波束数的限制。
本申请的实施例提供的数据传输控制方法基本原理为：第一通信装置获取天线接收的射频信号；第一通信装置将射频信号中的至少两部分信号通过至少两种功能切分方式处理生成至少两部分传输信号；其中，射频信号中的每部分信号通过一种功能切分方式处理，且射频信号中的不同部分信号的功能切分方式不同；功能切分方式用于确定第一通信装置与第二通信装置在处理射频信号中的部分信号时的功能切分；第一通信装置向第二通信装置发送至少两部分传输信号。例如，射频信号中的至少两部分信号包括第一部分信号和第二部分信号，其中，第一通信装置和第二通信装置采用第一功能切分方式对第一部分信号进行处理；第一通信装置和第二通信装置采用第二功能切分方式对第二部分信号进行处理。例如，第一功能切分方式可以是option.7-2a切分方式，第二功能切分方式可以是option.7-new切分方式，对于第一部分信号，第一通信装置可以将第一部分信号经过射频模块、时频转换模块、以及数字波束赋形模块的处理后，发送至第二通信装置，由第二通信装置对第一部分信号进行解映射模块及其之后的其他功能模块的处理；对于第二部分信号，第一通信装置可以对第二部分经过射频模块、时频转换模块、数字波束赋形模块、解映射模块、信道估计模块以及均衡模块部分的处理后发送第二通信装置，由第二通信装置进行频时转换模块及其之后的其他功能模块的处理；这样，实现第一通信装置与第二通信装置采用多种功能切分方式进行数据传输。这样相对于第一部分信号通过option.7-2a切分方式处理后发送至第二通信装置，第二部分信号通过option.7-new切分方式处理后发送至第二通信装置，能够使得避免全部射频信号均通过option.7-2a切分方式处理时，第一通信装置与第二 通信装置之间的接口带宽不能满足需求，同时，第一通信装置仅将第二部分信号通过option.7-new切分方式处理发送至第二通信装置，避免了将全部射频信号均在第一通信装置通过option.7-new切分方式处理造成的第一通信装置复杂度较高的问题。
结合图1示出的基站，本申请的实施例提供了第一通信装置的组成示意图，如图4所示，第一通信装置可以包括至少一个处理器41、通信接口42。其中，通信接口42与一个或多个处理器41耦合；第一通信装置通过所述通信接口与其他设备通信，处理器用于执行存储器中的计算机程序代码，使得第一通信装置执行本申请的实施例提供的数据传输控制方法。

此外，图5中示出的设备结构并不构成对第二通信装置的限定，第二通信装置可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
基于上述的基站以及硬件，本申请的实施例提供一种数据传输控制方法，参照图6所示，包括如下步骤：
101、第一通信装置获取天线接收的射频信号。
102、第一通信装置将射频信号中的至少两部分信号通过至少两种功能切分方式处理生成至少两部分传输信号。
其中，射频信号中的每部分信号通过一种功能切分方式处理，且射频信号中的不同部分信号的功能切分方式不同；功能切分方式用于确定第一通信装置与第二通信装置在处理射频信号中的部分信号时的功能切分。
这里至少两种功能切分方式可以包括第一功能切分方式和第二功能切分方式。
第一功能切分方式可以是option.7-1、option.7-2切分方式、option.7-3切分方式、option.7-6切分方式、option7-2a切分方式以及option7-new切分方式中的任意一种，第二功能切分方式可以是option.7-1、option.7-2切分方式、option.7-3切分方式、option.7-6切分方式、option7-2a切分方式以及option7-new切分方式中的任意一种，当然，第一功能切分方式和第二功能切分方式需要采用不同的功能切分方式。另外在本领域衍生的其他功能切分方式也应该包含在第一功能切分方式以及第二功能切分方式内。
第一通信装置将射频信号中的至少两部分信号通过至少两种功能切分方式处理生成至少两部分传输信号，可以理解为第一通信装置分别将射频信号中的一部分信号通过一种功能切分方式处理生成一部分传输信号。第一通信装置将射频信号中的一部分信号通过一种功能切分方式处理生成一部分传输信号，可以理解为第一通信装置对射频信号中的一部分信号按照一种功能切分方式中由第一通信装置需要完成的功能进行处理。例如，第一功能切分方式为option7-2a切分方式，第一通信装置对射频信号中的一部分信号需要完成RF模块、FFT模块以及BF模块的处理，然后生成一部分传输信号。
103、第一通信装置向第二通信装置发送至少两部分传输信号。
相应地，第二通信装置接收第一通信装置发送的至少两部分传输信号。
104、第二通信装置分别对至少两部分传输信号进行至少两种功能切分方式处理。
其中每部分传输信号对应采用一种功能切分方式处理，且不同部分的传输信号的功能切分方式不同；功能切分方式用于确定所述第一通信装置与第二通信装置在处理所述传输信号时的功能切分。
第二通信装置将射频信号中的至少两部分传输信号通过至少两种功能切分方式处理，可以理解为第二通信装置分别将一部分传输信号通过一种功能切分方式处理。第二通信装置将射频信号中的一部分传输信号通过一种功能切分方式处理，可以理解为第二通信装置对一部分传输信号按照一种功能切分方式中由第二通信装置需要完成的功能进行处理。例如，功能切分方式为option7-2a切分方式，第二通信装置对一部分传输信号需要完成解映射模块、信道估计模块、均衡模块、频时转换模块、解调模块、比特级处理模块以及MAC模块的处理。
例如，第一功能切分方式是option.7-2a切分方式，第一通信装置直接将射频信号中的第一部分信号经过射频模块、时频转换模块以及数字波束赋形模块的处理后发送至第二通信装置，由第二通信装置对第一部分信号进行信道估计模块及其之后的其他功能模块的处理；例如第二功能切分方式是option.7-new切分方式，第一通信装置仍然需要对射频信号中的第二部分信号依次经过射频模块、时频转换模块以及数字波束赋形模块、解映射模块、信道估计模块以及均衡模块的的处理，然后发送至第二通信装置进行频时转换模块及其之后的其他功能模块的处理；这样，实现第一通信装置与第二通信装置采用多种功能切分方式进行数据传输。
其中，该数据传输控制方法还包括：第一通信装置将射频信号分为至少两部分信号。需要说明的是，第一通信装置可以在接收到射频信号后将射频信号分为至少两部分信号，或者，第一通信装置对射频信号进行第一处理；然后第一通信装置将第一处理后的射频信号分为至少两部分信号。第一处理至少包括模数转换处理；或者，第一处理可以包括模数转换处理，或者第一处理可以包括模数转换处理以及时频转换处理，或者第一处理可以包括模数转换处理、时频转换处理以及波束赋形处理等等，当然根据功能切分方式的不同，第一处理还可以包括更多上行方向(即数据从第一通信装置到第二通信装置的传输方向)的功能。可选的，第一处理可以是至少两种切分方式共有的处理，例如，第一功能切分方式是option.7-2a切分方式，第二功能切分方式是option.7-new切分方式时，第一处理可以为射频模块的功能，或者第一处理可以包括射频模块以及时频转换模块的功能，或者第一处理可以包括射频模块、时频转换模块以及数字波束赋形模块的功能。
以下示例中，以第一功能切分方式为option7-2a切分方式，第二功能切分方式为option7-new切分方式，第一处理包括射频模块、时频转换模块以及数字波束赋形模块的功能为例，参照图7所示，提供一种数据传输控制方法，包括如下步骤：
201、第一通信装置接收用户设备发送的射频信号。
202、第一通信装置对射频信号进行模数转换处理，生成时域的数字信号。
203、第一通信装置对时域的数字信号进行时频转换处理，生成频域的数字信号。
204、第一通信装置对频域的数字信号进行波束赋形处理生成波束域的数字信号。
205、第一通信装置将波束域的数字信号分为至少两部分信号，其中该至少两部分 信号包括第一部分信号和第二部分信号。
当然，该方案中只是以在步骤205中将波束域的数字信号分为至少两部分信号为例进行说明，在其他方案中，也可以是在步骤201后将射频信号分为两部分信号，其中第一部分信号依次经过模数转换处理、时频转换处理以及波束赋形处理生成第一部分传输信号。第二部分信号依次经过模数转换处理、时频转换处理、波束赋形处理、解映射处理、信道估计处理以及均衡处理，生成第二部分传输信号。此外，也可以是在射频信号经过步骤202、203、204任意一步的处理之后分为两部分信号。
206、第一通信装置将第一部分信号作为第一部分传输信号发送至第二通信装置。
其中，由于第一部分传输信号由第一通信装置直接发送至第二通信装置并由第二通信装置对其执行波束赋形之后的处理，即对于射频信号中的第一部分信号第一通信装置和第二通信装置按照option7-2a切分方式处理。由于第一部分信号在第一通信装置上仅经过射频RF模块、时频转换模块、以及数字波束赋形BF模块的处理，因此第一部分信号的处理对第一通信装置的计算复杂度要求较低。
207、第一通信装置将第二部分信号进行解映射处理。
208、第一通信装置将解映射处理后的第二部分信号进行信道估计后进行均衡处理，生成第二部分传输信号，其中第二部分传输信号为频域的用户层信号。
209、第一通信装置将第二部分传输信号发送至第二通信装置。
其中，射频信号由第一通信装置依次经过模数转换处理、时频转换处理以及波束赋形处理分为第一部分信号和第二部分信号，第二部分信号又经解映射处理、信道估计处理以及均衡处理，然后生成第二部分传输信号发送至第二通信装置。即对于第二部分信号第一通信装置和第二通信装置按照option7-new切分方式处理。此时，第一通信装置和第二通信装置之间接口上传输的数据流量与配对层数(即第二信号上每个RB承载的用户数据流的流数)相关，一般的配对层数远小于天线数或波束数，因此，第二部分传输信号的数据量小于第二部分信号的数据量，这样可以大幅降低第一通信装置和第二通信装置之间传输流量，支持更多天线或波束数解调。
210、第二通信装置接收第一通信装置发送的第一部分传输信号，对第一部分传输信号进行解映射模块及其之后其他功能模块对应的处理。
例如，第二通信装置可以对第一部分传输信号依次进行解映射模块、信道估计模块、均衡模块、频时转换模块、解调模块、比特级处理模块、以及介质访问控制MAC实体等功能模块对应的处理。
211、第二通信装置接收第一通信装置发送的第二部分传输信号；对第二部分传输信号进行频时转换模块及其之后其他功能模块对应的处理。
例如，第二通信装置可以对第二部分传输信号依次进行频时转换模块、解调模块、比特级处理模块、以及介质访问控制MAC实体等功能模块对应的处理。
上述方案中，对第一通信装置接收的射频数据的处理过程中，通过205第一处理后的射频信号分成两部分信号，实现了数据传输控制过程中对第一通信装置和第二通信装置的option.7-2a切分方式和option7-new切分方式的混合，即将射频信号中的一部分信号通过option7-2a切分方式处理，将射频信号中的另一部分信号通过option7-new切分方式处理，这样相比全部采用option7-2a切分方式，本申请的技术方 案可以降低在第一通信装置和第二通信装置传输带宽受限、第一通信装置处理复杂度受限情况下，部分带宽采用Option7-2a，部分采用option7-new，可以有效平衡CPRI接口前传流量，同时能分担第一通信装置和第二通信装置的处理复杂度。以上仅是以option7-2a切分方式和option7-new切分方式的混合切分为例进行说明，当然本申请不限于option.7-2a切分方式和option.7-new切分方式的混合，还包括将option.7-2a切分方式或option.7-new切分方式简单变型后多种切分方式的混合。例如，在步骤205还可以将第一处理后的射频信号分为三部分，第一部分信号和第二部分信号分别参考步骤201-210中提供的方式处理，第三部分信号以在频时转换模块之后的切分方式进行，即对第三部分信号第一通信装置经过信道估计模块、均衡模块、频时转换模块对应的功能处理后发送至第二通信装置。
针对上述实施例中步骤102以及205，第一通信装置将射频信号分成至少两部分信号，并分别采用不同的功能切分方式进行处理，具体可以参照如下方式实施：
方式一：射频信号可以包括不同用户的信号，第一通信装置可以将该不同用户的信号分成至少两部分信号，第一通信装置和第二通信装置在处理每部分信号时可以采用不同的功能切分方式，例如，射频信号可以包括M+N个用户的信号，第一通信装置可以将M+N个用户的信号分成至少两部分信号，例如M个用户的信号分为第一部分信号；N个用户的信号分为第二部分信号，第一通信装置和第二通信装置在处理该M个用户的信号可以采用第一功能切分方式，第一通信装置和第二通信装置在处理该N个用户的信号可以采用第二功能切分方式。当然若第一通信装置在对射频信号进行第一处理后，分为两部分信号，则第一通信装置具体为将进行第一处理后的射频信号中的M个用户的信号分为第一部分信号，N个用户的信号分为第二部分信号。
其中，第一通信装置可以存储有配置信息以确定如何将射频信号分成至少两部分信号以及每部分信号的处理方式。该配置信息中可以配置第一通信装置和第二通信装置在处理M个用户标识对应的M个用户信号采用option.7-2a切分方式，第一通信装置和第二通信装置在处理N个用户标识对应的N个用户信号采用option.7-new切分方式，例如该配置信息可以包括M个用户标识和option.7-2a切分方式的映射关系，N个用户标识和option.7-new切分方式的映射关系。其中该配置信息可以采用静态方式配置在第一通信装置中，或者可以由基站的无线资源管理(radio resource management，RRM)实体通过层2(L2，数据链接层)消息发送给第一通信装置。
方式二：射频信号中包括第一用户的第一带宽的信号和第一用户的第二带宽的信号。第一通信装置将第一用户的第一带宽和第二带宽的信号分别采用不同的功能切分方式，例如：第一通信装置将射频信号中第一用户的第一带宽的信号分为第一部分信号；第一通信装置将射频信号中第一用户的第二带宽的信号分为第二部分信号。第一通信装置和第二通信装置在处理该第一用户的第一带宽的信号可以采用第一功能切分方式，第一通信装置和第二通信装置在处理该第一用户的第二带宽的信号可以采用第二功能切分方式。当然若第一通信装置在对射频信号进行第一处理后，分为两部分信号，则第一通信装置具体为将进行第一处理后的射频信号中的第一用户的第一带宽的信号分为第一部分信号，第一用户的第二带宽的信号分为第二部分信号。
其中，第一通信装置可以存储有配置信息以确定如何将射频信号分成至少两部分 信号以及每部分信号的处理方式。该配置信息中可以配置第一通信装置和第二通信装置在处理第一用户标识对应的第一带宽的信号时采用option.7-2a切分方式，第一通信装置和第二通信装置在处理第一用户标识对应的第二带宽的信号时采用option.7-new切分方式，例如该配置信息可以包括用户A的用户标识以及用户A采用option.7-2a切分方式的带宽，以及用户A采用option.7-new切分方式的带宽。其中该配置信息可以采用静态方式配置在第一通信装置中，或者可以由基站的无线资源管理实体通过层2(L2，数据链接层)消息发送给第一通信装置。
方式三：射频信号可以承载在不同的信道上，例如射频信号至少承载在两个信道(第一信道和第二信道上)上。第一通信装置将第一信道和第二信道上承载的信号分别采用不同的功能切分方式，例如：第一通信装置将第一信道承载的射频信号分为第一部分信号；第一通信装置将第二信道承载的射频信号分为第二部分信号。第一通信装置和第二通信装置在处理该第一信道承载的射频信号时可以采用第一功能切分方式，第一通信装置和第二通信装置在处理该第二信道承载的射频信号时可以采用第二功能切分方式。当然若第一通信装置在对射频信号进行第一处理后，分为两部分信号，则第一通信装置具体为将进行第一信道承载的第一处理后的射频信号分为第一部分信号，第二信道承载的第一处理后的射频信号分为第二部分信号。
其中，第一通信装置可以存储有配置信息以确定如何将射频信号分成至少两部分信号以及每部分信号的处理方式。该配置信息中可以配置第一通信装置和第二通信装置在处理第一信道承载的射频信号时采用option.7-2a切分方式，第一通信装置和第二通信装置在处理第一信道承载的射频信号时采用option.7-new切分方式，例如该配置信息可以包括第一信道标识和option.7-2a切分方式的映射关系，以及第一信道标识和option.7-new切分方式的映射关系。其中该配置信息可以采用静态方式配置在第一通信装置中，或者可以由基站的无线资源管理实体通过层2(L2，数据链接层)消息发送给第一通信装置。
方式四：第一通信装置可以根据第一通信装置与第二通信装置之间的传输带宽将射频信号分成至少两部分信号，以使至少两部分传输信号的数据量之和小于或等于第一通信装置与第二通信装置之间的传输带宽。例如：第一通信装置和第二通信装置之间传输带宽为25G，(其中该传输带宽可以为第一通信装置和第二通信装置之间的接口或通信线缆能够承受的最大带宽)，需要支持5G 100M带宽上行4层32天线接收。如果采用option7-2a切分方式，第一通信装置和第二通信装置之间传输的数据量需求达到47Gbps；如果采用option7-new切分方式，第一通信装置和第二通信装置之间的传输的数据量需求仅有5.45Gbps，但第一通信装置完成了信道估计、均衡等复杂的处理，处理开销增加，第一通信装置功耗增加。采用本本申请的技术方案，假设47Gbps中60％的数据量采用option7-new切分方式，40％的数据量采用Option7-2a切分方式，第一通信装置和第二通信装置之间的传输流量可以大幅下降到22.07Gbps，满足了25G带宽约束，同时，第一通信装置和第二通信装置各完成一部的信道估计和均衡，第一通信装置处理复杂度下降，第一通信装置功耗下降。如果第二通信装置和第一通信装置之间传输带宽限制为20G，相应的通过调整option7-2a切分方式与option7-new切分方式的数据量的比例为35％：65％，即可以满足带宽约束。
方式五：射频信号承载在至少两个资源块RB上，每个资源块RB上承载预定数量的用户数据流数；可以根据射频信号中各RB上的用户数据流数，第一通信装置对不同数据流数的RB承载的射频信号分别采用不同的功能切分方式，例如：第一通信装置获取每个RB承载的用户数据流数后；第一通信装置将用户数数据流数大于等于流数阈值的至少一个RB承载的射频信号分为第一部分信号；第一通信装置将用户数数据流数小于流数阈值的至少一个RB承载的射频信号分为第二部分信号。第一通信装置和第二通信装置在处理用户数数据流数大于等于流数阈值的至少一个RB承载的射频信号时可以采用第一功能切分方式，第一通信装置和第二通信装置在处理该用户数数据流数小于流数阈值的至少一个RB承载的射频信号时可以采用第二功能切分方式。当然若第一通信装置在对射频信号进行第一处理后，分为两部分信号，则第一通信装置具体为将用户数数据流数大于等于流数阈值的至少一个RB承载承载的第一处理后的射频信号分为第一部分信号，用户数数据流数小于流数阈值的至少一个RB承载的第一处理后的射频信号分为第二部分信号。
其中，第一通信装置可以存储有配置信息以确定如何将射频信号分成至少两部分信号以及每部分信号的处理方式。该配置信息中可以包含上述的流数阈值以及每个资源块上的用户数据流数。由于RB上的配对层数越多对应的用户数据流数越多，则处理复杂度越高，为降低第一通信装置的处理复杂度，对于配对层数小的RB，例如配对层数为2的RB优先采用option.7-new切分方式；对于配对层数大的RB，例如某一RB上配对层数8层，该RB优先采用option.7-2a切分方式。
方式六：第一通信装置根据以下各项中的任意一项或多项：第一信号中资源块RB承载的用户数据流的空中接口特征、用户数据流使用的演进协议版本、用户数据流使用的接收机类型，将预定处理后的射频信号分为至少两部分信号。
其中，空中接口特征包括MCS(modulation and coding scheme，调制与编码速率)、速度状态以及是否小区边缘用户。例如，对于JIRC CoMP(joint interference rejection combining coordinate multi point，联合抗干扰组合多点协作传输)方案中，需要用户在服务小区与协作小区的波束域接收信号合并后送入均衡模块进行联合均衡，若采用option.7-new切分方式，则第一通信装置已经将波束域的数字信号分别在服务小区和协作小区分别均衡，因此option.7-new切分方式不支持JIRC CoMP。因此对于小区边缘用户，可以通过基站的无线资源管理实体向第一通信装置发送配置信息，以配置将射频信号中的小区边缘用户的用户数据流，分为第一部分信号。此外，配置将第一信号中的MCS高、运动速度快的用户的用户数据流，分为第一部分信号，即采用option.7-2a切分方式；配置将第一信号中的MCS低、运动速度慢的用户的信号，分为第二部分信号，即采用option.7-new切分方式。
此外，信道估计模块和均衡模块等配置在第一通信装置中时，割裂了符号级(例如信道估计模块、均衡模块到解调模块为符号级处理)和比特级处理流程(解调模块之后为比特级处理)，由于迭代接收机需要比特级处理模块输出的译码软信息进行信息重构后反馈回信道估计模块重新进行处理，因此option.7-new不利于支持需要符号级和比特级信息交互的迭代接收机。因此对于迭代接收机的受益用户，可以通过基站的无线资源管理实体向第一通信装置发送配置信息，以配置将射频信号中的迭代接收 机的受益用户的用户数据流，分为第一部分信号，即采用option.7-2a切分方式。
此外，用户数据流使用的演进协议版本，迭代NoMA(none orthogonal multi aceess，非正交多址)接收机的性能由于线性NoMA接收机，因此option.7-new不利于支持迭代接收机，因此对于使用的演进协议版本NoMA的用户数据流，可以通过基站的无线资源管理实体向第一通信装置发送配置信息，配置第一通信装置将其分为第一部分信号，即采用option.7-2a切分方式。对于使用的演进协议版本OFDM(orthogonal frequency division multiplexing)的用户数据流，可以通过基站的无线资源管理实体向第一通信装置发送配置信息，配置第一通信装置将其分为第二部分信号，即采用option.7-new切分方式。
当然若第一通信装置在对射频信号进行第一处理后，分为两部分信号，则第一通信装置具体为将第一处理后的射频信号根据第一信号中资源块RB承载的用户数据流的空中接口特征、用户数据流使用的演进协议版本、用户数据流使用的接收机类型中的任意一项或多项分为至少两部分信号。
