技术领域
本公开涉及通信领域，更具体地，涉及一种信号处理设备及数据传输方法。
背景技术
在目前的蜂窝无线通信系统中，分布式接入网设备已经作为一种主要的接入网设备形态。一些分布式接入网设备包括基带单元(Baseband Unit，BBU)和射频拉远单元(Radio Remote Unit，RRU)，其支持第一频段范围是有限的。随着技术的演进，另一些分布式接入网设备包括BBU和有源天线单元(Active Antenna Unit，AAU)，其支持不同于第一频段范围的第二频段范围。
为了满足不同业务的需求，运营商需要提供同时支持第一频段范围和第二频段范围的接入网设备。目前运营商会同时部署RRU和AAU来实现此目的，但是由于RRU和AAU需要分别安装，因此复杂度高，并且硬件成本过高。

结合图3，以选项7-1为例：针对下行传输，由BBU执行物理高层的编码、速率匹配、加扰、调制、层映射、预编码、资源单元(Resource Element，RE)映射、波束赋形(Beamforming，BF)端口扩展等，并由AAU执行物理底层的逆快速傅里叶变换(inverse Fast Fourier Transform，iFFT)和循环移位(Cyclic Prefix，CP)添加等。针对上行传输，由AAU执行物理底层的CP移除和快速傅里叶变换(Fast Fourier Transform，FFT)，并由BBU执行物理高层的端口缩减、RE解映射、信道估计、分集组合、均衡、逆离散傅里叶变换(inverse Discrete Fourier Transform，iDFT)、解调制、解扰、解速率匹配、解码等。关于选项7-2和选项7-3可以结合图3，本公开中不再罗列。
示例性地，关于选项7-1、选项7-2和选项7-3可以参照3GPP TS 38.816(如15.0.0)中第4.2节的介绍，关于选项8可以参照3GPP TS 38.801(如14.0.0)中第11.1.2.8节的介绍.但是应注意，图3示出的切分方式仅是示意，不能解释为对本公开的实施例的限制。
可理解的是，本公开中的切分模式也可以被称为切分方式或协议切分模式等，在一些场景下，切分模式可以被用于表征RRU或AAU与BBU之间的切分。例如，在BBU包括CU和DU时，切分方式可以表示AAU与DU之间的切分。
如上所述，RRU使用CPRI接口与BBU连接，且支持第一频段范围；AAU使用eCPRI接口与BBU连接，且支持第二频段范围。为了满足不同业务的需求，运营商需要提供同时支持第一频段范围和第二频段范围的接入网设备。通过将RRU和BBU分别部署的方式不仅结构复杂，而且导致较高的成本。
针对上述问题以及在类似场景中的潜在其他问题，本公开的实施例提供了一种信号处理设备，其可以通过光纤与第二信号处理设备连接，且支持两种不同的切分模式，也就是说能够同时支持第一频段范围和第二频段范围。这样，能够降低设备的硬件复杂度，并且降低安装成本。以下将结合图4至图11详细描述根据本公开的实施例。可理解，本公开的实施例不限于上述提出的BBU和RRU以及BBU与AAU的场景，还可以被适用于其他的场景。
图4示出了根据本公开的实施例的接入网设备400的一个示意框图。接入网设备400包括第一信号处理设备410和第二信号处理设备420，并且第一信号处理设备410与第二信号处理设备420通过光纤430进行连接。

可理解，在一些示例中，实现转换功能的转换子模块530也可以被称为数据桥(bridge)或其他名称，本公开对此不限定。本公开的实施例中，调度模块412可以是由第一信号处理设备410的控制面(图中未示出)进行配置的，例如可以按照不同载波对应的切分模式进行配置。
在本公开的一些实施例中，第一信号处理设备410可以是通过对如图2所示的AAU 220进行升级改造而得到的。例如，可以在如图2所示的AAU 220的基础上，通过增加调度模块412和第一处理模块413以将AAU 220升级为第一信号处理设备410。如此，能够充分地利用已有设备，避免大规模的设备替换，进一步降低成本。
如图4所示，第二信号处理设备420可以包括第一基带模块421、第二基带模块422、转换模块423和接口模块424。第一基带模块421连接到转换模块423，转换模块423和第二基带模块422连接到接口模块424。第一基带模块421可以被配置为生成或处理时域数据。第二基带模块422可以被配置为生成或处理以太网数据。转换模块423可以被配置为实现时域数据与以太网数据之间的转换。接口模块424可以被配置为经由光纤430与第一信号处理设备410进行以太网数据传输。具体而言，转换模块423可以将来自第一基带模块421的时域数据转换为以太网数据，可以将来自接口模块424的以太网数据转换为时域数据。
可选地，第二信号处理设备420还可以包括调度模块425。调度模块425可以连接到转换模块423和第二基带模块422，调度模块425还可以连接到接口模块424。调度模块425可以被配置为将来自接口模块424的以太网数据调度到转换模块423或第二基带模块422。相应地，转换模块423可以将来自调度模块425的以太网数据转换为时域数据，再将转换后的时域数据提供给第一基带模块421。
可理解，在一些示例中，实现转换功能的转换模块423也可以被称为数据桥或其他名称，本公开对此不限定。在一些示例中，可以理解调度模块425能够实现以太网数据的分发功能，相应地也可以将调度模块425称为分发模块，本公开对此不限定。
在本公开的一些实施例中，第二信号处理设备420可以是通过对如图1所示的BBU 110进行如图2所示的BBU 210进行升级改造而得到的。例如，可以在如图1所示的BBU 110的基础上，通过增加第二基带模块422和转换模块423，并将原CPRI接口替换为eCPRI接口以将BBU 110升级为第二信号处理设备420。可以在如图2所示的BBU 210的基础上，通过增加第一基带模块421和转换模块423以将BBU 210升级为第二信号处理设备420。如此，能够充分地利用已有设备，避免大规模的设备替换，进一步降低成本。
可以将从第二信号处理设备420到第一信号处理设备410，以经由第一信号处理设备410的天线模块415发射出去的传输称为下行链路传输。可以将经由第一信号处理设备410的天线模块415接收，并从第一信号处理设备410到第二信号处理设备420的传输称为上行链路传输。
应注意，尽管在图4和图5中示出了第一信号处理设备410包括多个模块，第二信号处理设备420包括多个模块，但是在图4或图5中的模块仅是示意，在实际场景中，第一信号处理设备410和第二信号处理设备420可以包括更少或更多的模块。例如天线模块415可以独立于第一信号处理设备410，即第一信号处理设备410可以不包括天线模块415，等等。本公开中不再罗列。
应理解，本公开的实施例中对模块或单元的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时也可以有另外的划分方式，另外，在公开的实施例中的各功能单元可以集成在一个单元中，也可以是单独物理存在，也可以两个或两个以上单元集成为一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
下面将结合如下的图6至图8所示的信令交互图来更为详细地描述本公开的一些实施例。
图6示出了根据本公开的一些实施例的数据传输过程600的信令交互图。图6中涉及第一信号处理设备410和第二信号处理设备420，并且过程600为从第二信号处理设备420到第一信号处理设备410的下行链路传输。
第二信号处理设备420的第一基带模块421生成610时域数据。具体地，第一基带模块421可以通过编码、速率匹配、…、添加CP等一系列操作生成时域数据。
时域数据也可以被称为同相正交(In-phase Quadrature，IQ)数据，或者可以被称为基带正交采样数据，或者可以被称为CPRI数据或其他名称，本公开对此不限定。可选地，第一基带模块421所生成的时域数据可以是用户面(User Plane)的以同相或正交调制的数字基带数据。
第一基带模块421所生成的时域数据可以包括对应于第一数量的天线通道数的多个IQ数据流。可选地，可以将第一基带模块421所生成的时域数据称为多路第一IQ数据，且多路的数量等于第一数量，例如1、2、4或8中的任一值。
时域数据的传输基本单位为基本帧(base frame)，例如一个基本帧的时间长度为1/3.84MHz＝260.41667纳秒(ns)。一个基本帧可以包括16个样点，其中第1个样点用于传输控制字，第2个样点至第16个样点用于传输IQ数据。为了便于描述可以将基本帧中除去第1个样点之外的其余15个样点称为码片(chip)，也就是说，一个基本帧包括1个样点的传输控制字以及15个样点的码片。
可理解，尽管上述的示例中，码片包括15个样点，但是本公开的实施例不限于此，例如码片所包括的样点的数量可以等于8或其他值等。另外，上述的“样点”也可以被称为字(word)或其他名称等，本公开对此不限定。
样点的位宽可以表示样点包括多少个比特(bit)，从而可理解，位宽可以觉得码片所包括的bit数。在具体实现中，第一基带模块421的基带配置信息可以包括位宽，也就是说，可以预先将位宽配置在第一基带模块421中。本公开的实施例中对位宽的具体值不作限定，例如位宽可以等于15bit或其他值等。
第二信号处理设备420的转换模块423将时域数据转换620为以太网数据。
具体而言，转换模块423可以通过将时域数据中的多个码片进行组包，以得到对应的以太网数据。
在一些实施例中，转换模块423可以将时域数据中的码片进行依次拼接，并将拼接之后的数据作为以太网数据的负载。如图7示出了根据本公开的一些实施例的将时域数据转换为以太网数据的情形700的一个示意图。
如图7所示，时域数据710的基本单位为基本帧712，基本帧712包括控制字7121和码片7122。如图7所示，时域数据710的基本单位为基本帧712，基本帧712包括控制字7121和码片7122。以太网数据720可以包括传输网络层报头721、公共报头722、服务报头723和负载724，可选地还可以包括填充725。示例性地，可以将多个码片7122进行组包并作为以太网数据720的负载724。
在本公开的一些实施例中，以太网数据720的报文所包括的多个码片的数量可以基于以下因素来确定：第一数量、码片所包括的样点的数量、样点的位宽以及传输的带宽等。
举例而言，假设带宽为20MHz，该带宽对应的以太网数据的最大传输单元(Maximum Transmission Unit，MTU)为1500字节(byte)、包头长度为64字节。假设第一数量等于4，码片包括的样点的数量等于8，样点的位宽等于15。作为一例，可以确定多个码片的数量为：将(1500-64)/(4×8×15×2/8)下取整，即11。以此方式，能够充分地利用传输带宽，确保以太网的传输效率，避免资源浪费。
可理解，上述确定多个码片的数量的方式仅是示意，在实际场景中，也可以多个码片的数量可以等于其他的值，例如可以等于比上述方式确定的数量更小的值，例如10或9等，本公开对此不限定。
第二信号处理设备420的接口模块424经由光纤430将以太网数据传输630到第一信号处理设备410。相应地，第一信号处理设备410的接口模块411可以接收到来自第二信号处理设备420的以太网数据。
第一信号处理设备410的调度模块412基于传输配置信息，将以太网数据调度640到第一处理模块413。
在本公开的一些实施例中，传输配置信息可以是由第二信号处理设备420预先发送到第一信号处理设备410的。参照图6，第二信号处理设备420的接口模块424将传输配置信息发送601到第一信号处理设备410，相应地，第一信号处理设备410的接口模块411可以接收到传输配置信息。
在一些实施例中，传输配置信息可以包括是否由第一处理模块413进行处理的指示信息。举例而言，该指示信息可以被理解为是第一处理模块413处理数据的开关，例如可以为1或0。可理解，该指示信息也可以为其他的形式，本公开对此不限定。如果该指示信息指示由第一处理模块413进行处理，则第一信号处理设备410的调度模块412将从接口模块411接收到的以太网数据调度到第一处理模块413。相反，如果该指示信息指示不由第一处理模块413进行处理，则第一信号处理设备410的调度模块412将从接口模块411接收到的以太网数据调度到第二处理模块414。
在一些实施例中，传输配置信息可以包括第一指示信息和第二指示信息，其中第一指示信息指示第一频段范围与第一处理模块413之间的对应关系，第二指示信息指示第二频段范围与第二处理模块414之间的对应关系。举例而言，从接口模块411接收到的以太网数据的某字段可以携带频率信息，如果该频率信息位于第一频段范围，则第一信号处理设备410的调度模块412将从接口模块411接收到的以太网数据调度到第一处理模块413。如果该频率信息位于第二频段范围，则第一信号处理设备410的调度模块412将从接口模块411接收到的以太网数据调度到第二处理模块414。
应注意的是，本公开的实施例中的传输配置信息也可以包括其他的指示形式，从而调度模块412可以基于传输配置信息，能够确定将来自接口模块411的以太网数据调度到第一处理模块413还是第二处理模块414。在图6的过程600中，假设调度模块412将以太网数据调度到第一处理模块413。
第一处理模块413对来自调度模块412的以太网数据，按照第一切分模式进行处理。第一切分模式可以为时域切分模式。可选地，第一切分模式可以是支持CPRI协议的切分模式，结合图3，该第一切分模式可以为如图3所示的选项8。示例性地，第一处理模块413对以太网数据进行RF处理，而不执行物理层的处理。
参照图6，转换子模块530将以太网数据转换650为时域数据。具体地，转换子模块530可以将以太网数据转换为第一数量的多路第一时域数据。
在本公开的一些实施例中，第一数量可以是由第二信号处理设备420预先配置到第一信号处理设备410的。在一些实施例中，如601中的传输配置信息可以包括第一数量。在另一些实施例中，第一数量可以独立于传输配置信息，例如第二信号处理设备420通过另一单独的信令将第一数量告知第一信号处理设备410。
转换子模块530可以基于以太网数据的负载的拆分确定对应的第一数量的多路第一时域数据。以太网的负载可以为eCPRI负载，转换子模块530可以将负载按照码片的大小进行拆分，并在码片的基础上添加控制字而作为基本帧，从而得到多路第一时域数据。
波束赋形子模块540将第一数量的多路第一时域数据转换为第二数量的多路第二时域数据，其中第二数量大于第一数量。
具体而言，波束赋形子模块540可以基于第一数量的多路第一时域数据以及多个第一天线权重参数，来确定第二数量的多路第二时域数据。
在本公开的一些实施例中，第二数量和/或多个第一天线权重参数可以是由第二信号处理设备420预先配置到第一信号处理设备410的。在一些实施例中，如601中的传输配置信息可以包括第二数量和/或多个第一天线权重参数。在另一些实施例中，第二数量和/或多个第一天线权重参数以独立于传输配置信息，例如第二信号处理设备420通过另一单独的信令将第二数量和/或多个第一天线权重参数告知第一信号处理设备410。示例性地，第二数量可以对应于天线模块415的天线通道数，例如第二数量可以等于或小于天线模块415的总通道数。
为了描述方便，可以将第一数量表示为N1，将第二数量表示为N2，且N1<N2。在一些实施例中，可以将N1路第一时域数据中的至少部分进行复制，得到N2路时域数据；然后将N2路时域数据中的每路乘以对应的第一天线权重参数，从而得到N2路第二时域数据。
举例而言，假设N1＝4，N2＝32。可以将N1路第一时域数据中的每一路时域数据复制8份，从而得到32路时域数据，例如32路时域数据中的第1路至第8路为N1路第一时域数据中的第1路第一时域数据，32路时域数据中的第9路至第16路为N1路第一时域数据中的第2路第一时域数据，32路时域数据中的第17路至第24路为N1路第一时域数据中的第3路第一时域数据，32路时域数据中的第25路至第32路为N1路第一时域数据中的第4路第一时域数据。可选地，多个第一天线权重参数为第二数量的第一天线权重参数，可以将多个第一天线权重参数依次表示为wt1、wt2、…wtN2。那么，可以将32路时域数据中的第i路乘以wti(i＝1，2，…，N2)作为N2路第二时域数据中的第i路第二时域数据。
应注意，上述对波束赋形子模块540基于第一数量的多路第一时域数据得到第二数量的多路第二时域数据的实施例仅是示意，本公开不限于此，例如波束赋形子模块540可以将N1路第一时域数据中的第j路(j＝1，2，…，N1)第一时域数据复制N2份，并将复制后的N2份分别乘以对应的得到第一天线权重参数wti(i＝1，2，…，N2)。
应注意，本公开实施例中所描述的第一处理模块413对数据的处理过程仅是示意，在实际场景中，还可以包括其他的处理，例如功放、滤波等。
第一信号处理设备410的天线模块415传输670多路第二时域数据。具体地，天线模块415可以通过其N2个天线通道将N2个第二时域数据发送到终端设备。
如此，本公开实施例中的第二信号处理设备420的转换模块423可以将时域数据转换为以太网数据，从而能够经由eCPRI光纤传输到第一信号处理设备410。这样能够支持更多的小区，提升空口的性能。并且，第一信号处理设备410的第一处理模块413能够按照第一切分模式处理来自第二信号处理设备420的以太网数据，从而能够支持第一频段范围。
图8示出了根据本公开的一些实施例的数据传输过程800的信令交互图。图8中涉及第一信号处理设备410和第二信号处理设备420，并且过程800为从第二信号处理设备420到第一信号处理设备410的下行链路传输。
第二信号处理设备420的第二基带模块422生成810以太网数据。
第二信号处理设备420的接口模块424经由光纤430将以太网数据传输820到第一信号处理设备410。相应地，第一信号处理设备410的接口模块411可以接收到来自第二信号处理设备420的以太网数据。
第一信号处理设备410的调度模块412基于传输配置信息，将以太网数据调度830到第二处理模块414。
在本公开的一些实施例中，传输配置信息可以是由第二信号处理设备420预先发送到第一信号处理设备410的。参照图8，第二信号处理设备420的接口模块424将传输配置信息发送801到第一信号处理设备410，相应地，第一信号处理设备410的接口模块411可以接收到传输配置信息。关于该传输配置信息可以参照上述结合图6的601所描述的实施例，为了简洁，这里不再重复。
第二处理模块414对来自调度模块412的以太网数据，按照第二切分模式进行处理840。第二切分模式可以为物理层内部切分模式。可选地，第二切分模式可以是支持eCPRI协议的切分模式，结合图3，该第二切分模式可以为如图3所示的选项7-1或选项7-2或选项7-3。示例性地，第二处理模块414对以太网数据进行物理底层处理和RF处理，而不执行物理高层的处理。以第二切分模式是选项7-1为例，第二处理模块414所执行的处理可以包括iFFT和添加CP等操作。
应注意，本公开实施例中所描述的第二处理模块414对数据的处理过程仅是示意，在实际场景中，该处理过程可以包括例如频域波束赋形、功放、滤波等。在一些示例中，关于第二处理模块414的具体操作可以参照已有技术中的AAU的操作等。
第一信号处理设备410的天线模块415传输850下行链路数据。
如此，本公开实施例中的第二信号处理设备420的第二基带模块422能生成以太网数据，从而能够经由eCPRI光纤传输到第一信号处理设备410。并且，第一信号处理设备410的第二处理模块414能够按照第二切分模式处理来自第二信号处理设备420的以太网数据，从而能够支持第二频段范围。

在本公开的一些实施例中，传输配置信息可以是由第二信号处理设备420预先发送到第一信号处理设备410的。参照图9，第二信号处理设备420的接口模块424将传输配置信息发送901到第一信号处理设备410，相应地，第一信号处理设备410的接口模块411可以接收到传输配置信息。
在一些实施例中，传输配置信息可以包括是否由第一处理模块413进行处理的指示信息。举例而言，该指示信息可以被理解为是第一处理模块413处理数据的开关，例如可以为1或0。可理解，该指示信息也可以为其他的形式，本公开对此不限定。如果该指示信息指示由第一处理模块413进行处理，则第一信号处理设备410的调度模块412将从天线模块415接收到的上行链路数据调度到第一处理模块413。相反，如果该指示信息指示不由第一处理模块413进行处理，则第一信号处理设备410的调度模块412将从天线模块415接收到的上行链路数据调度到第二处理模块414。
在一些实施例中，传输配置信息可以包括第一指示信息和第二指示信息，其中第一指示信息指示第一频段范围与第一处理模块413之间的对应关系，第二指示信息指示第二频段范围与第二处理模块414之间的对应关系。举例而言，天线模块415接收到的上行链路数据的某字段可以携带频率信息，如果该频率信息位于第一频段范围，则第一信号处理设备410的调度模块412将从天线模块415接收到的上行链路数据调度到第一处理模块413。如果该频率信息位于第二频段范围，则第一信号处理设备410的调度模块412将从天线模块415接收到的上行链路数据调度到第二处理模块414。
应注意的是，本公开的实施例中的传输配置信息也可以包括其他的指示形式，从而调度模块412可以基于传输配置信息，能够确定将来自天线模块415接收到的上行链路数据调度到第一处理模块413还是第二处理模块414。在图9的过程900中，假设调度模块412将上行链路数据调度到第一处理模块413。
第一处理模块413对来自调度模块412的上行链路数据，按照第一切分模式进行处理。第一切分模式可以为时域切分模式。可选地，第一切分模式可以是支持CPRI协议的切分模式，结合图3，该第一切分模式可以为如图3所示的选项8。示例性地，第一处理模块413对上行链路数据进行RF处理，而不执行物理层的处理。
参照图9，波束赋形子模块540将上行链路数据转换930为第一数量的多路第一时域数据，其中第一数量小于第二数量。
在本公开的一些实施例中，第一数量可以是由第二信号处理设备420预先配置到第一信号处理设备410的。在一些实施例中，如901中的传输配置信息可以包括第一数量。在另一些实施例中，第一数量可以独立于传输配置信息，例如第二信号处理设备420通过另一单独的信令将第一数量告知第一信号处理设备410。

在本公开的一些实施例中，多个第二天线权重参数可以是由第二信号处理设备420预先配置到第一信号处理设备410的。在一些实施例中，如901中的传输配置信息可以包括多个第二天线权重参数。在另一些实施例中，多个第二天线权重参数以独立于传输配置信息，例如第二信号处理设备420通过另一单独的信令将多个第二天线权重参数告知第一信号处理设备410。
为了描述方便，可以将第一数量表示为N1，将第二数量表示为N2，且N1<N2。在一些实施例中，可以将N2路第二时域数据中的每路乘以对应的第二天线权重参数，从而得到N2路时域数据；然后将N2路时域数据中的至少部分进行合并，得到N1路第一时域数据。
举例而言，假设N1＝4，N2＝32。可选地，多个第二天线权重参数为第二数量的第二天线权重参数，可以将多个第二天线权重参数依次表示为wr1、wr2、…wrN2。可以将N2路第二时域数据中的第i路第二时域数据乘以wri(i＝1，2，…，N2)作为N2路时域数据中的第i路时域数据。然后，可以将N2路时域数据中第1路至第8路进行合并(例如求和)作为N1路第一时域数据中的第1路第一时域数据，将N2路时域数据中第9路至第16路进行合并(例如求和)作为N1路第一时域数据中的第2路第一时域数据，将N2路时域数据中第17路至第24路进行合并(例如求和)作为N1路第一时域数据中的第3路第一时域数据，将N2路时域数据中第25路至第32路进行合并(例如求和)作为N1路第一时域数据中的第4路第 一时域数据。
应注意，本公开实施例中所描述的第一处理模块413对数据的处理过程仅是示意，在实际场景中，还可以包括其他的处理，例如功放、滤波等。
转换子模块530将第一数量的多路第一时域数据转换940为以太网数据。具体地，转换子模块530的转换操作类似于前述结合图6所描述的第二信号处理设备420的转换模块423进行转换620的操作，为了简洁，这里不再赘述。
第一信号处理设备410的接口模块411将以太网数据传输950到第二信号处理设备420。相应地，第二信号处理设备420的接口模块424可以接收到来自第一信号处理设备410的以太网数据。
第二信号处理设备420的调度模块425将以太网数据调度960到转换模块423。具体而言，调度模块425可以基于以太网数据的频率信息进行调度。如果该频率信息位于第一频段范围，则第二信号处理设备420的调度模块425将从接口模块424接收到的以太网数据调度到转换模块423。如果该频率信息位于第二频段范围，则第二信号处理设备420的调度模块425将从接口模块424接收到的以太网数据调度到第二基带模块422。在图9的过程900中，假设调度模块425将以太网数据调度到转换模块423。
第二信号处理设备420的转换模块423将以太网数据970转换为时域数据。具体地，转换模块423可以将以太网数据转换为第一数量的多路第一时域数据。
转换模块423可以基于以太网数据的负载的拆分确定对应的第一数量的多路第一时域数据。以太网的负载可以为eCPRI负载，转换模块423可以将负载按照码片的大小进行拆分，并在码片的基础上添加控制字而作为基本帧，从而得到多路第一时域数据。
第二信号处理设备420的第一基带模块421对时域数据进行处理980。具体地，第一基带模块421可以通过移除CP、FFT、…、解码等一系列操作对时域数据进行处理。
图10示出了根据本公开的一些实施例的数据传输过程1000的信令交互图。图10中涉及第一信号处理设备410和第二信号处理设备420，并且过程1000为从第一信号处理设备410到第二信号处理设备420的上行链路传输。
第一信号处理设备410的天线模块415接收1010上行链路数据。
第一信号处理设备410的调度模块412基于传输配置信息，将上行链路数据调度1020到第二处理模块414。
在本公开的一些实施例中，传输配置信息可以是由第二信号处理设备420预先发送到第一信号处理设备410的。参照图10，第二信号处理设备420的接口模块424将传输配置信息发送1001到第一信号处理设备410，相应地，第一信号处理设备410的接口模块411可以接收到传输配置信息。
在一些实施例中，传输配置信息可以包括是否由第一处理模块413进行处理的指示信息。举例而言，该指示信息可以被理解为是第一处理模块413处理数据的开关，例如可以为1或0。可理解，该指示信息也可以为其他的形式，本公开对此不限定。如果该指示信息指示由第一处理模块413进行处理，则第一信号处理设备410的调度模块412将从天线模块415接收到的上行链路数据调度到第一处理模块413。相反，如果该指示信息指示不由第一处理模块413进行处理，则第一信号处理设备410的调度模块412将从天线模块415接收到的上行链路数据调度到第二处理模块414。
在一些实施例中，传输配置信息可以包括第一指示信息和第二指示信息，其中第一指示 信息指示第一频段范围与第一处理模块413之间的对应关系，第二指示信息指示第二频段范围与第二处理模块414之间的对应关系。举例而言，从天线模块415接收到的上行链路数据的某字段可以携带频率信息，如果该频率信息位于第一频段范围，则第一信号处理设备410的调度模块412将从天线模块415接收到的上行链路数据调度到第一处理模块413。如果该频率信息位于第二频段范围，则第一信号处理设备410的调度模块412将从天线模块415接收到的上行链路数据调度到第二处理模块414。
应注意的是，本公开的实施例中的传输配置信息也可以包括其他的指示形式，从而调度模块412可以基于传输配置信息，能够确定将来自天线模块415接收到的上行链路数据调度到第一处理模块413还是第二处理模块414。在图10的过程1000中，假设调度模块412将上行链路数据调度到第二处理模块414。
第二处理模块414对来自调度模块412的上行链路数据，按照第二切分模式进行处理1030。第二切分模式可以为物理层内部切分模式。可选地，第二切分模式可以是支持eCPRI协议的切分模式，结合图3，该第二切分模式可以为如图3所示的选项7-1或选项7-2或选项7-3。示例性地，第二处理模块414对以太网数据进行物理底层处理和RF处理，而不执行物理高层的处理。以第二切分模式是选项7-1为例，第二处理模块414所执行的处理可以包括CP移除和FFT等操作。
应注意，本公开实施例中所描述的第二处理模块414对数据的处理过程仅是示意，在实际场景中，该处理过程可以包括例如频域波束赋形、功放、滤波等。在一些示例中，关于第二处理模块414的具体操作可以参照已有技术中的AAU的操作等。并且可理解，经第二处理模块414处理后的数据为以太网数据。
第一信号处理设备410的接口模块411将以太网数据传输1040到第二信号处理设备420。相应地，第二信号处理设备420的接口模块424可以接收到来自第一信号处理设备410的以太网数据。
第二信号处理设备420的调度模块425将以太网数据调度1050到第二基带模块422。具体而言，调度模块425可以基于以太网数据的频率信息进行调度。如果该频率信息位于第一频段范围，则第二信号处理设备420的调度模块425将从接口模块424接收到的以太网数据调度到转换模块423。如果该频率信息位于第二频段范围，则第二信号处理设备420的调度模块425将从接口模块424接收到的以太网数据调度到第二基带模块422。在图10的过程1000中，假设调度模块425将以太网数据调度到第二基带模块422。
第二信号处理设备420的第二基带模块422对以太网数据进行处理1060。具体地，以第二切分模式是选项7-1为例，第二基带模块422可以对数据执行端口缩减、RE解映射、…、解码等一系列操作。
如此，本公开实施例中针对来自天线模块415的上行链路数据，能够由调度模块412基于传输配置信息调度到第一处理模块413或第二处理模块414，如此能够分别由第一处理模块413按照第一切分模式进行处理，由第二处理模块414能够按照第二切分模式进行处理，从而能够同时支持第一频段范围和第二频段范围。
应理解，在本公开的实施例中，“第一”，“第二”，“第三”等只是为了表示多个对象可能是不同的，但是同时不排除两个对象之间是相同的。“第一”，“第二”，“第三”等不应当解释为对本公开实施例的任何限制。
