Description

处理数据的方法和通信设备 技术领域
本发明实施例涉及通信领域，并且更具体地，涉及一种处理数据的方法和通信设备。
背景技术
随着诸如高清视频等高带宽应用的日益普及，在长期演进(Long Term Evolution，LTE)通信系统中做进一步演进以提升吞吐率的需求日趋迫切起来。当前几个潜在的演进方向包括：一、在演进基站(evolved NodeB，eNodeB)及用户设备(User Equipment，UE)端使用更多的天线做发送或接收；二、使用更高阶的调制方式。
通信系统在固定的带宽和固定的信道条件下，存在理论上的空口速率上限值。目前通信系统中使用了多种技术手段来逼近这一理论上限值，如时间分集、频率分集、空间分集。所谓分集是指通过多个信道(时间、频率、空间或其它维度)接收到承载相同信息的多个副本，由于多个信道的传输特性不同，信号多个副本的衰落就不会相同。接收机使用多个副本包含的信息能比较正确地恢复出原发送信号。一般来说，多个副本经历的信道越不同，分集效果越好。
然而，在基带处理过程中，采用上述分集技术手段来逼近空口速率上限值时，会导致数据处理量大大增加。这样，计算机的数据处理时间会大大延长。因此，需要一种新的数据处理方案来减小计算机的数据处理时间，进而保证通信系统的实时性。

具体实施方式
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的一部分实施例，而不是全部实施例。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的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
应理解，本发明实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，简称为“GSM”)系统、码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统、通用分组无线业务(General Packet Radio Service，简称为“GPRS”)、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency  Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex，简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称为“UMTS”)或全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为“WiMAX”)通信系统等。
在本发明实施例中，基站可以是GSM或CDMA中的基站(Base Transceiver Station，简称为“BTS”)，也可以是WCDMA中的基站(NodeB，简称为“NB”)，还可以是LTE中的演进型基站(Evolutional Node B，简称为“eNB”)，本发明并不限定，但为描述方便，下述实施例将以eNB为例进行说明。
在本发明实施例中，用户设备(User Equipment，简称为“UE”)可称之为终端(Terminal)、移动台(Mobile Station，简称为“MS”)或移动终端(Mobile Terminal)等，该用户设备可以经无线接入网(Radio Access Network，简称为“RAN”)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝”电话)或具有移动终端的计算机等，例如，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。
图1是本发明一个实施例的处理数据的方法的示意性流程图。为便于理解，结合图1对本发明实施例的数据处理过程做简要介绍。在通信设备作为数据发送方时，会按照图1所示的流程依次对数据进行处理，最后经由天线端口将数据发射出去。例如，在上行传输过程中，通信设备为用户设备UE；在下行传输过程中，通信设备为基站eNB。
目前，LTE系统选用的信道编码方式是Turbo编码。这里以Turbo编码为例对本发明实施例进行描述，应理解本发明实施例对信道编码方式不做限定，其它的信道编码方式也应落在本发明实施例的保护范围内。在Turbo编码过程中，先对输入的传输块做分割。为了降低存储、译码时间开销，将一个数据传输块(英文：Transport Block，简称：TB)切割成多个码块(英文：Code Block，简称：CB)。
如，将最大码块长度设置为6144比特，超过6144比特的传输块将会被分割成多个码块。然后，Turbo编码对每个码块做独立处理，每个码块经过Turbo编码后还会计算对应于每个码块的循环冗余校验(英文：Cyclic  Redundancy Check，简称：CRC)(图1中未示出)，用于接收端快速检测。以上步骤整体上称为Turbo编码。
在本发明实施例中，完成码块的CRC校验后，会按照每个码块做速率匹配，接着将各个码块的比特做级联。然后，分别对以上数据整体上做加扰、调制。或者，完成码块的CRC校验后，接着进行码块的加扰和调制，然后将各码块的符号做级联。最后，通信设备将处理后的数据通过天线端口发射出去。
根据本发明实施例的方法，通信设备不在信道编码后进行数据块的级联，而是在速率匹配或调制后再进行数据块的级联，进而提高了数据处理过程中的并行度。这样，本发明实施例能够缩小数据处理时间，为通信系统的实时性提供了保障。
下面将结合具体的例子详细描述本发明实施例。应注意，这些例子只是为了帮助本领域技术人员更好地理解本发明实施例，而非限制本发明实施例的范围。
图2是本发明另一实施例的处理数据的方法的示意性流程图。图2所示的方法由作为数据发送的通信设备执行，如UE或eNB。
201，将原始数据流分割为多个数据块。
例如，根据预设的数据块大小将数据划分为多个数据块，以便于通信设备对各个数据块进行独立的处理。
202，对多个数据块进行并行的数据块级的信道编码、速率匹配、加扰和调制，得到多个调制后的数据块。
例如，通信设备分别将每一个数据块作为一个独立的单元进行并行的数据处理。如，对数据块依次进行信道编码、速率匹配、加扰和调制。在信道编码速率匹配、加扰和调制过程中均以数据块的粒度进行并行地处理，也就是说在数据处理过程中各个数据块之间并不相互依赖。
203，对多个调制后的数据块做级联合并，得到级联合并后的新数据流。
例如，将步骤202中调制后得到的多个数据块做级联合并，得到新数据流，以便于通信设备通过天线端口将该新数据流发射出去。
基于上述技术方案，在本发明实施例中，通信设备不在信道编码后进行数据块的级联，而是调制后再进行数据块的级联，进而提高了数据处理过程中的并行度。这样，本发明实施例能够缩小数据处理时间，为通信系统的实 时性提供了保障。
可选地，作为一个实施例，对多个调制后的数据块做级联合并，得到级联合并后的新数据流时，对多个调制后的数据块做非顺序的级联合并，得到级联合并后的新数据流。
应理解，非顺序的的级联合并是指不按照各个数据块首尾连接的顺序将数据块合并。如，顺序的级联合并为：数据块1的第一个元素，数据块1的第二个元素，…，数据块1的最后一个元素，数据块2的第一个元素，…，最后一个数据块的最后一个元素。
可选地，作为一个实施例，对多个调制后的数据块做级联合并，得到级联合并后的新数据流时，先将多个调制后的数据块中的至少两个数据块的元素进行交织，得到多个交织后的新数据块。然后，将多个交织后的新数据块的元素顺序连接，得到新数据流。
其中，级联合并过程中使用的交织方式可以分别预配置在发送端设备和接收端设备侧。或者，发送端设备可以向接收端设备通知使用的交织方式。应理解，本发明实施例对此不做限定。
例如，通信设备分别在多个调制后的数据块中的至少两个数据块的元素进行交织生成新的数据块。假设有N个数据块，那么可随机挑选出M个数据块进行交织，其中M<N，且M与N均为正整数。
需要指出的是，一般来说，交织深度越大，则传输性能越好，但计算的复杂度升高，需要对更多的数据做位置搬移的计算和处理。因此M的选择可以取决于传输性能和复杂度两方面的折中考虑。其中，生成的新数据块的个数与进行交织的数据块的个数相同。例如：对4个数据块的元素进行交织，那么生成的新数据块也为4个，且每个数据块的元素个数未改变。
接着，通信设备将多个交织后的新数据块的元素进行顺序连接，合并后得到新数据流。也就是说，在级联合并过程中，通信设备并没有将数据做简单的顺序级联(如，数据块1的第一个符号，数据块1的第二个符号，…，数据块1的最后一个符号，数据块2的第一个符号，…，最后一个数据块的最后一个符号)。而是将交织后的新数据块做级联，来提高分集增益。这样，本发明实施例能够提高分集增益，进而进一步提高通信系统的空口速率。
可选地，作为另一实施例，若多个调制后的数据块的数量为偶数，将多 个调制后的数据块两两配对，并分别将配对的两个数据块中的元素进行交织，得到多个交织后的新数据块。
应理解，可任意选择两个数据块配为一对，本发明实施例对此不作限定。例如，假设数据块个数为NDB，通信设备可将第1个和第NDB/2+1个数据块放在一起进行元素交织，将第2个和NDB/2+2个数据块放在一起进行元素交织…将第NDB/2个数据块和第NDB个数据块放在一起进行元素交织。其中，最后得到的新数据块的元素个数保持不变。
若多个调制后的数据块的数量为奇数，在多个调制后的数据块中除去任意一个数据块，将其余数据块两两配对，并分别将配对的两个数据块中的元素进行交织，得到多个交织后的新数据块。
应理解，可任意排除一个数据块，也可任意选择两个数据块配为一对，本发明实施例对此不作限定。具体地，配对方式可参照前文描述的方法，为避免重复，在此不再赘述。
可选地，作为另一实施例，将多个调制后的数据块中的至少两个数据块的元素进行交织，得到多个交织后的新数据块时，可以先将多个调制后的数据块中的至少两个数据块的元素进行串行顺序排列，得到第一元素序列。然后，按照预设的规则，改变第一元素序列中元素的排列顺序，得到第二元素序列。最后，依次从第二元素序列中获取多个交织后的新数据块。
相似地，通信设备将多个交织后的新数据块的元素进行顺序连接，合并后得到新数据流。通信设备没有将数据做简单的顺序级联，而是将交织后的新数据块做级联，来提高分集增益。这样，本发明实施例能够提高分集增益，进而进一步提高通信系统的空口速率。
可选地，作为另一实施例，在对多个调制后的数据块做非顺序的级联合并，得到级联合并后的新数据流之后，通信设备将级联合并后的新数据流映射到对应的信号空间层，并通过相应的天线端口发射新数据流。
应理解，信号空间层是时间、频率以及空间的资源组合。具体的，通信设备分别将携带有新数据块的各数据流映射到对应的时间、频率以及空间的资源组合上，由于新数据块中的元素已作交织，故相当于原有的数据块的元素被分散映射到多个时频资源上，进而提高了通信系统的分集增益。
可选地，作为另一实施例，发送端设备还可以向接收端设备发送级联合并信息，级联合并信息包括级联合并过程中使用的交织方式的索引。具体地， 该级联合并信息可以通过下行控制信息或者其它控制信息携带，本发明实施例对此不做限定。
例如，在下行控制信息(Downlink Control Information，DCI)中增加一个字段用于指示交织方式的索引。这样，需要预先在接收方设备侧和发送方设备分别预配置交织方式索引表。接收端设备可以根据交织方式的索引从该索引表中确定对应的交织方式，以用于后续的数据解调等处理过程。具体地，交织方式也可以用一个交织函数p(r)表示。
假设调制后输出的数据块顺序为erk，r＝0,...,C-1，k＝0,...,Er-1，级联合并后输出的数据块顺序为fk，k＝0,...,G-1。
这样，可以通过执行以下程序来实现数据块的级联合并：
Figure PCTCN2015074347-appb-000001
执行以上程序后，级联合并模块输出的码块顺序为fk＝ep(rj)。其中，p(rj)为交织函数。
图3是本发明另一实施例的处理数据的方法的示意性流程图。在图3中以传输块(英文：Transport Block，简称：TB)和码块(英文：Code Block，简称：CB)为例进行描述。应理解，本发明实施例对数据块的大小和名称不做限定。
原始数据流中数据以TB为基本单元。按照预设的数据块粒度，通信设备先将TB分隔为码块(也即数据块)CB1,CB2,…,CBn。然后分别对各个码块做并行的数据处理，也即依次进行Turbo编码、速率匹配、加扰和调制。其中，在将TB分割为CB之前，可以先进行TB的CRC校验，图3中未示出。相似地，每个码块经过Turbo编码后还会计算对应于每个码块的CRC 校验，图3中也未示出。
然后，将调制后得到的各个CB的符号做非顺序的级联合并。例如，将调制后的各个CB做交织，再将交织后的CB做级联合并，以提高通信系统的分集增益。具体地，非顺序的级联合并方法可以参照前文描述的方法，为避免重复，在此不再赘述。
最后，将前述级联合并后的数据映射到信号空间层。由于新数据块中的符号已作交织，故相当于原有的数据块的符号被分散映射到多个时频资源上，进而提高了通信系统的分集增益。接着，通信设备通过相应地天线端口发射前述数据。
图4是本发明另一实施例的处理数据的方法的示意性流程图。图4所示的方法由作为数据发送的通信设备执行，如UE或eNB。
401，将原始数据流分割为多个数据块。
例如，根据预设的数据块大小将数据划分为多个数据块，以便于通信设备对各个数据块进行独立的处理。
402，对多个数据块进行并行的数据块级的信道编码和速率匹配，得到多个速率匹配后的数据块。
例如，通信设备分别将每一个数据块作为一个独立的单元进行并行的数据处理。如，对数据块依次进行信道编码和速率匹配。在信道编码和速率匹配过程中均以数据块的粒度进行并行的处理，也就是说在数据处理过程中各个数据块之间并不相互依赖。
403，将多个速率匹配后的数据块中的至少两个数据块的元素进行交织，得到多个交织后的新数据块。
404，将多个交织后的数据块的元素顺序连接，得到级联合并后的数据流。
例如，将步骤402中速率匹配后得到的多个数据块做级联合并，得到新数据流，并输出给下一级模块进行后续处理。具体地，通信设备可以分别在多个速率匹配后的数据块中的至少两个数据块的元素进行交织生成新的数据块。假设有N个数据块，那么可随机挑选出M个数据块进行交织，其中M<N，且M与N均为正整数。
需要指出的是，一般来说，交织深度越大，则传输性能越好，但计算的复杂度升高，需要对更多的数据做位置搬移的计算和处理。因此M的选择 可以取决于传输性能和复杂度两方面的折中考虑。其中，生成的新数据块的个数与进行交织的数据块的个数相同。例如：对4个数据块的元素进行交织，那么生成的新数据块也为4个，且每个数据块的元素个数未改变。
接着，通信设备将多个交织后的新数据块的元素进行顺序连接，合并后得到新数据流。也就是说，在级联合并过程中，通信设备并没有将数据做简单的顺序级联(如，数据块1的第一个符号，数据块1的第二个符号，…，数据块1的最后一个符号，数据块2的第一个符号，…，最后一个数据块的最后一个符号)。
405，对级联合并后的数据流进行加扰和调制，得到调制后的新数据流。
例如，在级联合并后的数据流整体上做加扰和调制，得到调制后的新数据流，以便于通信设备通过天线端口将该新数据流发射出去。
基于上述技术方案，在本发明实施例中，通信设备不是将数据块做顺序的合并，而是将交织后的新数据块顺序连接，以实现数据块的非顺序级联合并。这样，级联合并的数据块映射到不同的空间层后能够有更好的分集增益，提高了通信系统的空口速率。
可选地，作为另一实施例，若多个速率匹配后的数据块的数量为偶数，将多个速率匹配后的数据块两两配对，并分别将配对的两个数据块中的元素进行交织，得到多个交织后的新数据块。
应理解，可任意选择两个数据块配为一对，本发明实施例对此不作限定。例如，假设数据块个数为NDB，通信设备可将第1个和第NDB/2+1个数据块放在一起进行元素交织，将第2个和NDB/2+2个数据块放在一起进行元素交织…将第NDB/2个数据块和第NDB个数据块放在一起进行元素交织。其中，最后得到的新数据块的元素个数保持不变。
若多个速率匹配后的数据块的数量为奇数，在多个速率匹配后的数据块中除去任意一个数据块，将其余数据块两两配对，并分别将配对的两个数据块中的元素进行交织，得到多个交织后的新数据块。
应理解，可任意排除一个数据块，也可任意选择两个数据块配为一对，本发明实施例对此不作限定。具体地，配对方式可参照前文描述的方法，为避免重复，在此不再赘述。
可选地，作为另一实施例，将多个速率匹配后的数据块中的至少两个数据块的元素进行交织，得到多个交织后的新数据块时，可以先将多个速率匹 配后的数据块中的至少两个数据块的元素进行串行顺序排列，得到第一元素序列。然后，按照预设的规则，改变第一元素序列中元素的排列顺序，得到第二元素序列。最后，依次从第二元素序列中获取多个交织后的新数据块。
相似地，通信设备将多个交织后的新数据块的元素进行顺序连接，合并后得到新数据流。通信设备没有将数据做简单的顺序级联，而是将交织后的新数据块做级联，来提高分集增益。这样，本发明实施例能够提高分集增益，进而进一步提高通信系统的空口速率。
可选地，作为另一实施例，在对级联合并后的数据流进行加扰和调制，得到调制后的新数据流之后，通信设备将调制后的新数据流映射到对应的信号空间层，并通过相应的天线端口发射新数据流。
应理解，信号空间层是时间、频率以及空间的资源组合。具体的，通信设备分别将携带有新数据块的各数据流映射到对应的时间、频率以及空间的资源组合上，由于新数据块中的元素已作交织，故相当于原有的数据块的元素被分散映射到多个时频资源上，进而提高了通信系统的分集增益。
图5是本发明另一实施例的处理数据的方法的示意性流程图。在图3中以传输块TB和码块CB为例进行描述。应理解，本发明实施例对数据块的大小和名称不做限定。
原始数据流中数据以TB为基本单元。按照预设的数据块粒度，通信设备先将TB分隔为码块(也即数据块)CB1,CB2,…,CBn。然后分别对各个码块做并行的数据处理，也即依次进行Turbo编码和速率匹配。其中，在将TB分割为CB之前，可以先进行TB的CRC校验，图3中未示出。相似地，每个码块经过Turbo编码后还会计算对应于每个码块的CRC校验，图3中也未示出。
然后，将速率匹配后得到的各个CB的比特做非顺序的级联合并。例如，将速率匹配后的各个CB做交织，再将交织后的CB做级联合并，以提高通信系统的分集增益。具体地，非顺序的级联合并的方法可以参照前文描述的方法，为避免重复，在此不再赘述。
接着，在级联合并后得到的数据流整体上做加扰和调制。并将调制后得到的新数据流映射到信号空间层。由于新数据块中的符号已作交织，故相当于原有的数据块的符号被分散映射到多个时频资源上，进而提高了通信系统的分集增益。最后通信设备通过相应地天线端口发射前述数据。

可选地，作为一个实施例，级联单元603具体用于，对多个调制后的数据块做非顺序的级联合并，得到级联合并后的新数据流。
应理解，非顺序的的级联合并是指不按照各个数据块首尾连接的顺序将数据块合并。如，顺序的级联合并为：数据块1的第一个元素，数据块1的第二个元素，…，数据块1的最后一个元素，数据块2的第一个元素，…，最后一个数据块的最后一个元素。
可选地，作为一个实施例，级联单元603具体用于，将多个调制后的数据块中的至少两个数据块的元素进行交织，得到多个交织后的新数据块。然后，将多个交织后的新数据块的元素顺序连接，得到新数据流。
其中，级联合并过程中使用的交织方式可以分别预配置在发送端设备和接收端设备侧。或者，发送端设备可以向接收端设备通知使用的交织方式。应理解，本发明实施例对此不做限定。
