Abstract

本发明实施例提供一种基带处理单元和基站系统。利用本发明基带处理单元，实现基带频域资源池处理方式，从而有效减少现有基带资源池处理过程中传输带宽的消耗。

Description

基带处理单元和基站系统 技术领域
本发明实施例涉及通信技术，尤其涉及一种基带处理单元和基站系统。
背景技术
随着通用移动通信技术的长期演进(Long Term Evolution，简称LTE)商用进程的不断深入，基带资源池特性的商用需求变得越来越强烈。此需求主要来自于如下应用场景：随着LTE业务发展需求不断增长，越来越多的基站需要增加新一代基带单板来协助老一代基带单板提升规格、支持新特性，这样则对新老基带单板互助基带资源池有需求。同时在大事件(Big Event)场景下，例如新年夜、国庆节、音乐节等，单小区用户数规格需求很高，需要单小区具有共享整个单板/多个单板的能力。
LTE基带资源池包含下行基带资源池和上行基带资源池。其中，下行基带资源池具体采用如下时域合路方案，每个基带处理单元处理同一个小区的部分用户，各个基带处理单元各自完成同一个小区的比特级、频域、逆快速傅里叶变换(Inverse Fast Fourier Transformation，简称IFFT)时频变换的处理，各自得到同一个小区的多天线的时域数据；将同一个小区的来自各个基带处理单元的相同天线的时域数据按样点对齐进行合路，合路后得到一个小区的唯一的一套多天线的时域数据；将合路后的时域数据发送给中射频进行发射。而上行基带资源池具体采用如下时域复制分发方案，中射频将接收到的一个小区的多天线的时域数据发给时域数据复制模块；时域数据复制模块将一个小区的多天线的时域数据复制为多套，分别发送给多个基带处理单元；每个基带处理单元处理同一个小区的部分用户，各个基带处理单元使用收到的一个小区的多天线的时域数据各自完成同一个小区的快速傅里叶变换(Fast Fourier Transformation，简称FFT)、符号级、比特级的处理。
然而，下行基带资源池中，对于一个小区的多天线数据采用上述方 式进行时域合路，所以会导致合路前的时域数据量翻倍，从而消耗较大的传输带宽。相应的，上行基带资源池中，采用上述方式进行时域数据复制后传输会导致复制后的时域数据量翻倍，从而导致时域数据复制后的传输需要消耗较大的传输带宽，由此可知，随着通信技术的不断发展，基站需要处理的数据量也将呈现飞速增长，采用现有技术的基站的基带资源池的处理方式必然会导致基站中传输带宽的大量消耗。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例的基带处理单元包括主基带处理单元和辅基带处理单元，下面将结合具体实施例对本发明实施例的主基带处理单元和辅基带处理单元进行解释说明。
图1为本发明主基带处理单元实施例一的结构示意图，如图1所示，本实施例的装置可以包括：频域合路模块11、反变换模块12、变换模块13和频域分路模块14，其中，频域合路模块11用于根据调度指示信息获取主下行频域信号数据、各辅基带处理单元的辅下行频域信号数据、以及各辅下行频域信号数据对应的频域信号数据位置信息；根据各辅下行频域信号数据对应的频域信号数据位置信息将各辅下行频域信号数据和所述主下行频域信号数据进行频域合并获取完整下行频域信号数据，反变换模块12用于将所述完整下行频域信号数据变换为下行时域信号数据，并将所述下行时域信号数据发送给中射频单元，变换模块13用于接收所述中射频单元发送的上行时域信号数据，并将所述上行时域信号数据变换为上行频域信号数据，频域分路模块14用于根据调度指示信息和所述上行频域信号数据获取主上行频域信号数据、各辅基带处理单元的辅上行频域信号数据、以及各辅上行频域信号数据对应的频域信号数据位置信息；将各辅基带处理单元的辅上行频域信号数据和所述辅上行频域信号数据对应的频域信号数据位置信息分别发送给各辅基带处理单元。
其中，所述主下行频域信号数据和各辅下行频域信号数据为同一小区的下行频域信号数据，所述主上行频域信号数据和各辅上行频域信号数据为同一小区的上行频域信号数据，所述调度指示信息为资源池调度单元根据所述主基带处理单元和各辅基带处理单元的处理能力而生成的。
一个主基带处理单元有至少一个辅基带处理单元，该主基带处理单元的主下行频域信号数据和至少一个辅基带处理单元的辅下行频域信号数据为同一个小区的下行频域信号数据，而一个基站系统中可以包括多个主基带处理单元和与其协作处理的辅基带处理单元以进行不同小区的数据处理。主基带处理单元与至少一个辅基带处理单元间的数据处理分配由资源池调度单元根据各基带处理单元的处理能力生成调度指示信息以进行指示。
具体的，频域合路模块11和反变换模块12用于基站系统中多个基带处理单元间的下行基带频域资源池处理，其中，主基带处理单元的频域合路模块11根据调度指示信息获取其自身的主下行频域信号数据，和各辅基带处理单元的辅下行频域信号数据，根据各辅基带处理单元的辅下行频域信号数据和与其对应的频域信号数据位置信息将主下行频域信号数据和各辅基带处理单元的辅下行频域信号数据进行频域合并获取完整下行频域信号数据。获取到完整下行频域信号数据后，利用反变换模块12进行变换处理获取下行时域信号数据，该反变换模块12具体可以采用逆傅里叶变换、逆快速傅里叶变换或逆离散傅里叶变换将完整下行频域信号数据变换为下行时域信号数据。
由此可以理解，在现有技术中下行基带资源池处理中需要各基带处理单元分别完成频域、IFFT时频变换的处理后获取各基带处理单元的时域数据，将各基带处理单元的时域数据进行时域合路，这样会导致合路前各基带处理单元的时域数据传输占用大量传输带宽，与现有技术不同，本发明实施例是各辅基带处理单元将各自的辅下行频域信号数据发送给主基带处理单元，主基带处理单元对各辅下行频域信号数据和主下行频域信号数据进行频域合并，将完整下行频域信号数据变换为下行时域信号数据再发送给中射频单元，从而实现在主基带处理单元中完成频 域合并再进行时频变换，进而减小下行基带资源池处理中消耗的传输带宽。
具体的，变换模块13和频域分路模块14用于基站系统中多个基带处理单元间的上行基带频域资源池处理，其中，主基带处理单元的变换模块13接收中射频单元发送的上行时域信号数据，将该上行时域信号数据采用傅里叶变换、离散傅里叶变换或快速傅里叶变换进行时频变换为上行频域信号数据，获取该上行频域信号数据后频域分路模块14根据调度指示信息获取主上行频域信号数据、各辅基带处理单元的辅上行频域信号数据和与其对应的频域信号数据位置信息，将各辅基带处理单元的辅上行频域信号数据和与其对应的频域信号位置信息分别发送给各辅基带处理单元，以使由各辅基带处理单元和主基带处理单元分别对上行频域信号数据中的部分频域信号数据进行处理。
由此可以理解，在现有技术中上行基带资源池处理中需要将时域数据复制后分别发送给各基带处理单元，各基带处理单元分别进行FFT时频变换、符号级、比特级的处理，这样会导致时域数据复制后的传输消耗大量传输带宽，而与现有技术不同，本发明实施例主基带处理单元接收上行时域信号数据后，将该上行时域信号数据变换为上行频域信号数据，根据调度指示将需要在其他辅基带处理单元进行处理的部分上行频域信号数据分别发送给其他辅基带处理单元，从而实现在主基带处理单元中完成时频变换后仅向其他辅基带处理单元发送其要处理的上行频域信号数据，进而有效减小上行基带资源池处理中所消耗的传输带宽。
需要说明的是，本实施中频域合路模块11和反变换模块12具体用于下行基带资源池处理，而变换模块13和频域分路模块14具体用于处理上行数据上行基带资源池处理，使用本实施的基带处理单元可以仅使用频域合路模块11和反变换模块12进行下行基带资源池处理，也可以仅使用变换模块13和频域分路模块14进行上行基带资源池处理，也可以同时使用频域合路模块11、反变换模块12、变换模块13和频域分路模块14分别进行下行和上行基带资源池处理。
进一步的，第一方面，将本实施例的主基带处理单元具体用于下行基带频域资源池处理中，每个辅下行频域信号数据包括多个紧凑排放的 资源块数据，所述辅下行频域信号数据对应的频域信号数据位置信息用于标识各资源块数据在频域中的位置；频域合路模块11用于根据各辅下行频域信号数据对应的频域信号数据位置信息将各辅下行频域信号数据和所述主下行频域信号数据进行频域合并获取完整下行频域信号数据，具体可以为：所述频域合路模块11用于根据各资源块数据在频域中的位置将各资源块数据与所述主下行频域信号数据所包括的各资源块数据进行合并，获取完整下行频域信号数据。
可选的，所述辅下行频域信号数据对应的频域信号数据位置信息为二进制字符串，所述二进制字符串中的一个比特位对应一段频域位置，其中，比特位置1表示所述比特位对应的频域位置有一个资源块数据，比特位置0表示所述比特位对应的频域位置没有资源块数据；
所述频域合路模块11用于根据各辅下行频域信号数据对应的频域信号数据位置信息将各辅下行频域信号数据和所述主下行频域信号数据进行频域合并获取完整下行频域信号数据，具体可以为：所述频域合路模块用于将每个辅下行频域信号数据中的各资源块数据依次放入与所述辅下行频域信号数据对应的二进制字符串中比特位置1的频域位置；将所述主下行频域信号数据中的各资源块数据放入各辅下行频域信号数据对应的二进制字符串中相同比特位均为0的频域位置，获取完整下行频域信号数据。
具体的，辅基带处理单元向主基带处理单元发送的辅下行频域信号数据为按照资源块(Resource Block，简称RB)紧凑输出的数据，即该辅下行频域信号数据包括多个资源块数据，该多个资源块数据紧凑排放，从而可以有效减少在实现下行基带频域资源池处理过程中辅基带处理单元向主基带处理单元发送数据时所占用的传输带宽。辅基带处理单元在发送辅下行频域信号数据时会同时发送给辅下行频域信号数据对应的频域信号数据位置信息，该辅下行频域信号数据对应的频域信号数据位置信息用于指示该辅下行频域信号数据中各资源块数据在频域中的具体位置，以使主基带处理单元可以根据该位置信息将辅下行频域信号数据中的各资源块数据与主下行频域信号数据进行合并，获取完整下行频域信号数据。
进一步的，第二方面，将本实施例的主基带处理单元具体用于上行基带频域资源池处理中，每个辅上行频域信号数据包括多个紧凑排放的资源块数据，所述辅上行频域信号数据对应的频域信号数据位置信息用于标识各资源块数据在频域中的位置。可选的，所述辅上行频域信号数据对应的频域信号数据位置信息可以为二进制字符串，所述二进制字符串中的一个比特位对应一段频域位置，其中，比特位置1表示所述比特位对应的频域位置有一个资源块数据，比特位置0表示所述比特位对应的频域位置没有资源块数据。
对于上行基带频域资源池处理，主基带处理单元中的变换模块13接收中射频单元发送的上行时域信号数据，并将该上行时域信号数据变换为上行频域信号数据，获取到该上行频域信号数据后，主基带处理单元中的频域分路模块14根据调度指示信息将该上行频域信号数据进行出路处理获取主上行频域信号数据和各辅基带处理单元的辅上行频域信号数据，即将一个小区中不同的频域数据分别发送给各辅基带处理单元分别进行后续频域处理，该辅上行频域信号数据是以RB紧凑排放输出的，从而可以有效减小在实现上行基带频域资源池过程中主基带处理单元向各辅基带处理单元发送数据时所占用的传输带宽，进一步的，为了使辅基带处理单元在接收到辅上行频域信号数据可以正确获知各资源块数据的频域位置，则频域分路模块14会在生成各辅基带处理单元的辅上行频域信号数据时同时会生成该辅上行频域信号数据对应的频域信号数据位置信息，辅基带处理单元根据该位置信息可以准确获知各资源块数据所在的频域位置。
本发明实施例的主基带处理单元，对于下行数据，通过频域合路模块根据调度指示信息获取属于同一小区的主下行频域信号数据、各辅下行频域信号数据和各辅下行频域信号数据对应的频域信号数据位置信息，根据该各辅下行频域信号数据对应的频域信号数据位置信息将各辅下行频域信号数据和主下行频域信号数据进行频域合并获取完整下行频域信号数据，主基带处理单元的反变换模块将该完整下行频域信号数据变换为下行时域信号数据，并发送给中射频单元；而对于上行数据，通过变换模块接收中射频单元发送的上行时域信号数据，将其变换为上行 频域信号数据，再由频域分路模块根据调度指示信息从该上行频域信号数据中分离出各基带处理单元需要处理的各辅上行频域信号数据，将该各辅上行频域信号数据发送给各辅基带处理单元；由此实现基带频域资源池处理方式，从而有效减少现有基带资源池处理过程中传输带宽的消耗。
图2为本发明主基带处理单元实施例二的结构示意图，本实施例的主基带处理单元具体为下行基带频域资源池处理中的主基带处理单元，如图2所示，本实施例的装置在图1所示装置结构的基础上，进一步地，还可以包括：接收模块15和下行频域处理模块16，该接收模块15用于接收所述各辅基带处理单元分别发送的压缩辅下行频域信号数据；对各压缩辅下行频域信号数据进行解压缩，获取所述各辅基带处理单元的辅下行频域信号数据和所述辅下行频域信号数据对应的频域信号数据位置信息，该下行频域处理模块16用于根据所述调度指示信息对一小区的部分下行频域信号数据进行下行频域处理获取所述主下行频域信号数据，即主基带处理单元处理自身需要处理的下行频域信号数据。
在图1所示实施例的基础上，本实施例的主基带处理单元作为下行基带频域资源池处理中的主基带处理单元，在接收各辅基带处理单元发送的压缩辅下行频域信号数据时，接收模块15会对各压缩辅下行频域信号数据进行解压缩，获取各辅基带处理单元的辅下行频域信号数据和与其对应的频域信号数据位置信息，由此主基带处理单元接收的是压缩后的数据，可以进一步减少辅基带处理单元和主基带处理单元间传输数据所占用的传输带宽。
图3为本发明主基带处理单元实施例三的结构示意图，本实施例的主基带处理单元具体为上行基带频域资源池处理中的主基带处理单元，如图3所示，本实施例的装置在图1所示装置结构的基础上，进一步地，还可以包括：发送模块17和上行频域处理模块18，其中，该发送模块17用于对各辅基带处理单元的辅上行频域信号数据进行比特压缩，将压缩后的所述辅上行频域信号数据和所述辅上行频域信号数据对应的频域信号数据位置信息分别发送给各辅基带处理单元，上行频域处理模块18用于对所述主上行频域信号数据进行上行频域处理。
在图1所示实施例的基础上，本实施例的主基带处理单元作为上行基带频域资源池处理中的主基带处理单元，主基带处理单元中的频域分路模块在获取到各辅基带处理单元的辅上行频域信号数据后，发送模块16先对其进行比特压缩，将压缩后的辅上行频域信号数据和与其对应的频域信号数据位置信息发送给各辅基带处理单元，从而可以进一步有效减少主基带处理单元和辅基带处理单元间传输数据时所占用的传输带宽。
需要说明的是，前述实施例描述的基带处理单元，各模块的功能可通过处理器执行软件指令的方式实现，或者通过处理器执行软件指令并配合其它硬件电路的方式实现。
图4为本发明辅基带处理单元实施例一的结构示意图，如图4所示，本实施的装置可以包括：下行频域处理模块21、发送模块22、接收模块23和上行频域处理模块24，该下行频域处理模块21用于根据调度指示信息对一小区的部分下行频域信号数据进行下行频域处理获取辅下行频域信号数据，根据所述辅下行频域信号数据获取所述辅下行频域信号数据对应的频域信号数据位置信息，该发送模块22用于将所述辅下行频域信号数据和与其对应的频域信号数据位置信息发送给主基带处理单元，该接收模块23用于接收主基带处理单元发送的所述辅基带处理单元的辅上行频域信号数据和与其对应的频域信号数据位置信息，该上行频域处理模块用于根据所述辅基带处理单元的辅上行频域信号数据和与其对应的频域信号数据位置信息对所述辅上行频域信号数据进行频域处理。
其中，所述主下行频域信号数据和所述辅下行频域信号数据为同一小区的下行频域信号数据，所述主上行频域信号数据和所述辅上行频域信号数据为同一小区的上行频域信号数据，所述调度指示信息为资源池调度单元根据所述主基带处理单元和各辅基带处理单元的处理能力而生成的。
可选的，所述辅下行频域信号数据包括多个紧凑排放的资源块数据，所述辅下行频域信号数据对应的频域信号数据位置信息为二进制字符串，所述二进制字符串中一个比特位对应一段频域位置，所述下行频域处理模块21用于根据所述辅下行频域信号数据获取所述辅下行频域信号数据对应的频域信号数据位置信息，具体可以为：所述下行频域处理 模块用于将各资源块数据所在的频域位置对应的所述二进制字符串中的比特位置1，并将所述二进制字符串中其他比特位置0，生成所述辅下行频域信号数据对应的频域信号数据位置信息。
进一步的，所述下行频域处理模块21还用于，对所述辅下行频域信号数据进行比特压缩获取压缩后的所述辅下行频域信号数据；相应的，所述发送模块22具体用于将所述压缩后的所述辅下行频域信号数据和与其对应的频域信号数据位置信息发送给所述主基带处理单元。

本实施例的辅基带处理单元，在实现基带资源池过程中，与主基带处理单元之间仅发送或者接收有效的频域信号数据，从而可以有效减少传输带宽的消耗。
需要说明的是，前述实施例描述的辅基带处理单元，各模块的功能可通过处理器执行软件指令的方式实现，或者通过处理器执行软件指令并配合其它硬件电路的方式实现。下面采用两个具体的实施例，对上述实施例技术方案进行补充解释说明。
图5为本发明基带处理单元实现下行基带频域资源池的示意图，本实施例具体以两个基带处理单元之间实现下行频域资源池做具体说明，如图5所示，基带处理单元0作为辅基带处理单元，即为别的基带处理单元提供帮助，也可称之为资源池协作方，基带处理单元1作为主基带处理单元，即需要别的基带处理单元提供帮助，也可称之为资源池本地方，一个小区属于基带处理单元1，基带处理单元1处理该小区的RB或RE，而基带处理单元0也会协助处理该小区的一些RB或RE。如图5所示，基带处理单元1包括下行频域处理模块51、接收模块52、频域合路模块53和反变换模块54，基带处理单元0包括下行频域处理模块55和发送模块56。
具体的，基带处理单元0中下行频域处理模块55进行该小区部分用户数据的比特级处理和频域处理，将处理后的频域数据按RB/RE紧凑排 放，并配置该紧凑排放的RB/RE的bitmap，该bitmap用于标识各RB/RE在频域中的位置，具体该bitmap的生成过程可以为，在频域中一个RB/RE占用一段频域位置，对各RB/RE进行编号，即对每一段频域位置进行编号，一个编号对应该bitmap的一个比特位，若该编号对应的频域位置有RB/RE，则将该编号对应的bitmap的比特位置1，若该编号对应的频域位置没有RB/RE，则将该编号对应的bitmap的比特位置0，根据RB/RE在频域中的位置生成该bitmap。基带处理单元0中的发送模块56将该紧凑排放的RB/RE和其对应的bitmap发送给基带处理单元1，可选的，在发送给基带处理单元1之前，基带处理单元0还可以对该紧凑排放的RB/RE进行比特压缩，将压缩后的数据发送给基带处理单元1。
基带处理单元1中的下行频域处理模块51进步该小区其他部分用户数据的比特级处理和频域处理，将处理后的频域数据提供给频域合路模块53，基带处理单元1中接收模块52接收到基带处理单元0发送的紧凑排放的RB/RE和bitmap，若基带处理单元0有对该紧凑排放的RB/RE进行比特压缩，那么基带处理单元1的接收模块52会对其进行解压缩以获得该紧凑排放的RB/RE和bitmap，频域合路模块53根据该紧凑排放的RB/RE和bitmap将该紧凑排放的RB/RE和本地的处理后的频域数据进行频域合并获取完整频域信号数据，由反变换模块对该完整频域信号数据进行IFFT时频变换获取下行时域信号数据。
本实施例，基带处理单元1和基带处理单元0之间仅传输有效的频域数据，还可以进行数据压缩，从而可以有效减少传输带宽的消耗，并且，在实现下行基带资源池过程中，基带处理单元1和基带处理单元0进行时频变换时，仅需要在资源池本地方基带处理单元1中进行一次IFFT变换，从而相对于现有技术减少了时频变换的处理量。
图6为本发明基带处理单元实现上行基带频域资源池的示意图，本实施例具体以两个基带处理单元之间实现上行频域资源池做具体说明，如图6所示，基带处理单元0作为辅基带处理单元，即为别的基带处理单元提供帮助，也可称之为资源池协作方，基带处理单元1作为主基带处理单元，即需要别的基带处理单元提供帮助，也可称之为资源池本地方，一个小区属于基带处理单元1，基带处理单元1处理该小区的RB或RE，而 基带处理单元0也会协助处理该小区的一些RB或RE。如图6所示，基带处理单元1包括变换模块61、频域分路模块62、发送模块63和上行频域处理模块64，基带处理单元0包括接收模块65和上行频域处理模块66。
具体的，基带处理单元1接收该小区的时域数据，变换模块61对该小区的时域数据进行FFT时频变换获取该小区的频域数据并提供给频域分路模块62，频域分路模块62将该小区频域数据中的部分RB/RE输出给上行频域处理模块64进行后续频域处理，将另外一部分RB/RE按照紧凑排放生成紧凑排放的RB/RE和其对应的bitmap，该bitmap的具体生成过程可以参见图5所示实施例中bitmap的生成过程，此处不再赘述。发送模块63将该紧凑排放的RB/RE和其对应的bitmap发送给基带处理单元0，可选的，发送模块63在发送之前还可以对该紧凑排放的RB/RE比特压缩，将压缩后的该紧凑排放的RB/RE和其对应的bitmap发送给基带处理单元0。
基带处理单元0的接收模块65接收基带处理单元1发送的数据，基带处理单元1有对该紧凑排放的RB/RE进行压缩，那么接收模块65会对其进行解压缩获取该紧凑排放的RB/RE和其对应的bitmap，将该紧凑排放的RB/RE和其对应的bitmap提供给上行频域处理模块66，上行频域处理模块66根据该bitmap将该紧凑排放的RB/RE对应到各上行用户上，进行后续算法链路处理。
本实施例，基带处理单元1和基带处理单元0之间仅传输有效的频域数据，还可以进行数据压缩，从而可以有效减少传输带宽的消耗，并且，在实现上行基带资源池过程中，基带处理单元1和基带处理单元0进行时频变换时，仅需要在资源池本地方基带处理单元1中进行一次FFT变换，从而相对于现有技术减少了时频变换的处理量。
