Description

一种数据处理方法及其装置
本申请要求于2017年5月12日提交中国专利局、申请号为201710336210.1、申请名称为“一种数据处理方法及其装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种数据处理方法及其装置。
背景技术
长期演进(Long Term Evolution，LTE)系统中的物理下行信道处理流程可参见图1所示，发送端对码字(codeword，CW)进行加扰、调制处理，得到调制符号，然后对调制符号进行层映射处理，再对层映射处理之后的调制符号进行预编码处理，再对预编码处理之后的符号进行资源元素(Resource Element，RE)映射处理，将预编码处理之后的符号映射到时频资源上，最后，生成正交频分复用(Orthogonal Frequency Division Multiplex，OFDM)信号并通过天线端口(antenna port)进行发送。
其中，层映射和资源元素映射两个模块影响码字到层的映射方式。码字到层的映射级别可分为比特(bit)级、符号(symbol)级和码块(code block，CB)。bit级的映射发生在速率匹配模块之后，symbol级和CB级的映射发生在调制模块之后。码字到层的映射顺序主要是指码字在映射到层时，资源在层、时域、频域，3个维度上的映射顺序，例如，将调制处理得到的调制符号先映射到层，再映射到频域，最后映射到时域；或者将调制处理得到的调制符号先映射到层，再映射到时域，最后映射到频域。码字到层的映射级别和映射顺序，再结合交织，就构成了一种映射方式。
LTE系统采用映射级别为symbol级，映射顺序为先映射到层，再映射到频域，最后映射到时域，不做交织的码字到层的映射方式，可以实现时域集中分布的数据分布方式，即同一CB的数据在时域上集中分布，这样，有利于快速解调。但是，LTE系统所采用的码字到层的映射方式仅可以实现时域集中分布的数据分布方式，对于应用场景较多的新空口(New Radio，NR)系统，一种数据分布方式很难适应多种应用场景。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
本申请实施例可以应用于无线通信系统，无线通信系统通常由小区组成，每个小区包含一个基站(Base Station，BS)，基站向多个终端设备提供通信服务，其中基站连接到核心网设备，如图2所示。其中，基站包含基带单元(Baseband Unit，BBU)和远端射频单元(Remote Radio Unit，RRU)。BBU和RRU可以放置在不同的地方，例如：RRU拉远，放置于离高话务量的开阔区域，BBU放置于中心机房。BBU和RRU也可以放置在同一机房。BBU和RRU也可以为一个机架下的不同部件。
需要说明的是，本申请实施例提及的无线通信系统包括但不限于：窄带物联网系统(Narrow Band-Internet of Things，NB-IoT)、全球移动通信系统(Global System for Mobile Communications，GSM)、增强型数据速率GSM演进系统(Enhanced Data rate for GSM Evolution，EDGE)、宽带码分多址系统(Wideband Code Division Multiple Access，WCDMA)、码分多址2000系统(Code Division Multiple Access，CDMA2000)、时分同步码分多址系统(Time Division-Synchronization Code Division Multiple Access，TD-SCDMA)，长期演进系统(Long Term Evolution，LTE)、5G系统以及未来移动通信系统。
本申请实施例中，所述基站是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站(也称为小站)，中继站，接入点，传输接入点(Transmission Receiver point，TRP)等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在LTE系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB),在第三代(3rd Generation，3G)系统中，称为节点B(Node B，NB)等。为方便描述，本申请所有实施例中，上述为终端设备提供无线通信功能的装置统称为网络设备。
本申请实施例中所涉及到的终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。所述终端设备也可以称为移动台(Mobile Station，MS)、终端(Terminal)，还可以包括用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能手机(smart phone)、无线数据卡、个人数字助理(Personal Digital Assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(Machine Type Communication，MTC)终端等。为方便描述，本申请所有实施例中，上面提到的设备统称为终端设备。
本申请实施例中所涉及到的数据分布方式用于表示来自同一个码块的数据的分布情况。数据分布方式可以用于表示来自同一个码块的数据在时域维度的分布情况，例如，时域集中分布的数据分布方式用于表示来自同一个码块的数据在连续的至少一个时域符号上集中分布，时域分散分布的数据分布方式用于表示来自同一个码块的数据在多个时域符号上分散分布。数据分布方式还可以用于表示来自同一个码块的数据在空域维度的分布情况，也可以用于表示来自同一码块的数据在频域维度的分布情况。本申请所有实施例中，以时域集中分布的数据分布方式和时域分散分布的数据分布方式为例进行介绍，空域维度和频域维度的分布情况可类推。
请参见图3，是一种时域集中分布方式的数据分布示意图，每个CB尽可能地集中在一个或多个连续的时域符号分布，从而保证接收端对数据进行快速解调。请参见图4，是一种时域分散分布方式的数据分布示意图，每个CB被尽可能地分散放置在不同的时域符号上，例如图4中CB0被分散放置在第一个时域符号、第二个时域符号以及最后一个时域符号上，能够大大提高传输性能。
应理解，时域集中分布方式需要尽可能地将同一个CB的数据分布在一个时域符号，在一个时域符号放不下的情况下，再将该CB的剩余数据放置到相邻的时域符号上，以此类推，因此，在采用时域集中分布方式的情况下，同一个CB的数据分布在至少一个连续的时域符号。而时域分散分布方式虽然需要将同一个CB的数据分散放置，但是来自同一个CB的数据不一定会分散到全部可用的时域符号上，例如，共有10个可用的时域符号，一个CB可能只分散放置于其中的3个时域符号、5个时域符号或8个时域符号，这都应属于本申请实施例的时域分散分布方式。
其中，时域分散分布方式可以有以下三种方式：
第一时域分散分布方式，用于表示来自同一个码块的数据在资源单元内的所有时域符号上分散分布，所述资源单元为调度用户进行资源分配的基本单位；
第二时域分散分布方式，用于表示来自同一个码块的数据在所述资源单元内同一时隙的所有时域符号上分散分布；
第三时域分散分布方式，用于表示来自同一个码块的数据在所述资源单元内的N个时域符号上分散分布，N为大于1的整数。
具体地，时域分散分布的数据分布方式，可以包括不同的分散程度，该分散程度可以用来自同一个CB的数据所分布的时域符号数目衡量。来自同一CB的数据可以在资源单元中的所有时域符号上分散分布，也可以在资源单元中同一时隙的所有时域符号上分散分布，还可以在资源单元中的部分时域符号上分散分布，本申请实施例对此不作限定。应理解，上述资源单元(Resource Unit，RU)可以用作为调度用户进行资源分配的基本单位。一个资源单元占用频域内多个连续的子载波和时域内多个连续的符号(OFDM符号)。
本申请实施例提供的数据处理方法应用在NR系统中，主要应用在具有多种应用场景的NR系统中，多种应用场景可以包括但不限于增强移动带宽(Enhanced Mobile Broadband，eMBB)场景、超高可靠低时延通信(Ultra Reliable and Low Latency Communication，uRLLC)场景、海量物联网通信(Massive Machine Type Communication，mMTC)场景等。应用场景可以是网络设备根据终端设备的信道变化情况，确定该终端设备当前处于高速场景或低速场景，本申请实施例对此也不作限定。
应用本申请实施例可以实现集中分布和分散分布的数据分布方式，以满足NR系统中各种应用场景的需求。
下面将对本申请实施例提供的数据处理方法进行详细介绍。
请参见图5，图5是本申请实施例提供的一种数据处理方法的流程示意图，从网络设备与终端设备交互的角度进行介绍，该方法可以包括但不限于如下步骤：
步骤S201：网络设备对传输数据进行处理得到数据分布方式，所述处理包括对传输数据进行交织处理和按照映射顺序进行映射处理中的至少一种；所述数据分布方式用于表示来自同一个码块的数据的分布情况；
其中，所述数据分布方式用于表示来自同一个码块的数据在连续的至少一个时域符号上集中分布，即时域集中分布方式。或所述数据分布方式用于表示来自同一个码块的数据在多个时域符号上分散分布，即时域分散分布方式。
LTE系统采用映射顺序为先映射到层(空域映射)，再映射到频域，最后映射到时域，不做交织的码字到层的映射方式，可以实现时域集中分布的数据分布方式，但只能实现这一种数据分布方式。本申请实施例中，网络设备对传输数据进行交织处理，或按照映射顺序进行映射处理，或对传输数据进行交织处理+按照映射顺序进行映射处理，不仅可以实现时域集中分布的数据分布方式，还可以实现时域分散分布的数据分布方式，还可以实现空域集中分布的数据分布方式、空域分散分布的数据分布方式等等。
其中，映射顺序可以指空域、时域、频域三个维度的映射先后顺序。空域映射是指图1所示的层映射模块的映射，时域映射和频域映射是指图1所示的资源元素映射模块的映射。根据图1所示可知，空域映射在时频映射之前，本申请实施例中可以不限定三个维度的映射顺序，例如先频域映射，再时域映射，最后空域映射。
需要说明的是，当只按照映射顺序进行映射处理时，本申请实施例中的映射顺序不包 括先空域映射，再频域映射，最后时域映射的映射顺序，即不包括LTE系统中所采用的映射顺序。
本申请实施例以空域映射在时频映射之前为例进行介绍，主要针对时域映射与频域映射的先后顺序进行介绍。
LTE系统中的不做交织(No interleaving)指在图1所示的调制模块后，码字或码块中各个调制符号的顺序不变。
本申请实施例中的交织的方式可以包括频域交织、时域交织和时频交织，下面将对这三种交织方式进行介绍。
类似于LTE标准中的资源块(Resource Block)RB和RB对(RB pair)，在本申请中提供了一种资源单元(Resource Unit)，该资源单元可以用作为调度用户进行资源分配的基本单位。资源单元占用频域内多个连续的子载波，和时域内多个连续的符号(OFDM符号)。
假设调度资源在时域上有N个OFDM符号，第n个OFDM符号内可用于数据传输(物理下行共享信道(Physical Downlink Shared Channel，PDSCH))的子载波数目为Pn。
频域交织(F interleaving)，也就是每个OFDM符号的交织，该种交织将CW划分为N个部分，每个部分有Pn个调制符号，然后改变每个部分内调制符号的顺序，以一个部分为例，改变该部分中Pn个调制符号的顺序。(Pn及N的取值如上所述)
将资源单元内的N个OFDM符号划分为Q部分(1≤Q<N)，假设第j部分有Nj(j＝0，…，(Q-1))个OFDM符号，若j＝0，则该部分用于数据传输的子载波数目为
Figure PCTCN2018086476-appb-000001
若j>0，则第j部分用于数据传输的子载波数据为
Figure PCTCN2018086476-appb-000002
时频交织(F+T interleaving)，是一种跨OFDM符号交织，该种交织将CW划分为Q个部分(1≤Q<N)。在每个部分内，分别改变调制符号的顺序。时频交织后，在第j部分的每个OFDM符号对应的调制符号数目内，来自不同CB的调制符号顺序也会交叉。
时域交织(T interleaving)，也是一种跨OFDM符号交织，该种交织将CW划分为Q个部分(1≤Q<N)。在每个部分内，分别改变调制符号的顺序。与时频交织不同的是，利用时域交织后，在第j部分的每个OFDM符号对应的调制符号数目内，来自不同CB的调制符号顺序排放，不会出现顺序交叉。
LTE系统中的先频域映射再时域映射的映射顺序，将通过图1所示的预编码模块处理之后的调制符号，按照顺序先放第一个可用于数据传输的OFDM符号的子载波，第一个可用于数据传输的OFDM符号完成后，再放第二个可用于数据传输的OFDM符号的子载波，第二个可用于数据传输的OFDM符号完成后，再放第三个可用于数据传输的OFDM符号，依次完成所有OFDM符号的数据映射。
本申请实施例中的先频域映射再时域映射的映射顺序与LTE系统中的相同。
本申请实施例中的先时域映射再频域映射的映射顺序，将通过图1所示的预编码模块处理之后的调制符号，按照顺序先放第一个子载波对应的所有OFDM符号(中间不用于PDSCH的不放)，然后再放第二个子载波对应的所有OFDM符号(中间不用于PDSCH的 不放)，依次完成所有子载波的数据映射。
在一种可能实现的方式中，所述网络设备对所述传输数据进行交织处理，按照频域映射在时域映射之前的映射顺序对所述传输数据进行映射处理，可以得到数据分布方式此时的映射顺序为LTE系统中的先频域映射再时域映射的映射顺序。若所述网络设备对所述传输数据进行频域交织处理，按照频域映射在时域映射之前的映射顺序对所述传输数据进行映射处理，则可以得到时域集中分布的数据分布方式，相比LTE系统中不做交织，进行频域交织处理可以获得频域分集增益。若所述网络设备对所述传输数据进行时频交织处理或时域交织处理，按照频域映射在时域映射之前的映射顺序对所述传输数据进行映射处理，则可以得到时域分散分布的数据分布方式，若进行时域交织处理，则可以获得时域分集增益；若进行时频交织处理，则可以获得时域分集增益和频域分集增益。
在一种可能实现的方式中，所述网络设备按照时域映射在频域映射之前的映射顺序对所述传输数据进行映射处理，此时不做交织，可以得到时域分散分布的数据分布方式。该种可能实现的方式，可以获得时间分集增益。
在一种可能实现的方式中，所述网络设备对所述传输数据进行交织处理，按照时域映射在频域映射之前的映射顺序对所述传输数据进行映射处理，可以得到时域分散分布的数据分布方式。若进行频域交织处理，则可以获得时域分集增益和频域分集增益。若进行时域交织处理，则可以获得时域分集增益。若进行时频交织处理，则可以获得时域分集增益和频域分集增益。

可选地，所述终端设备可以根据预设的第一对应关系，来确定数据分布方式，不同的DMRS的图样对应不同的数据分布方式，或不同的DMRS端口号对应不同的数据分布方式。由于所述网络设备和所述终端设备进行数据传输时采用的DMRS的图样或DMRS的端口号已知，例如为第一DMRS图样或第一DMRS端口号，所述终端设备可以根据该第一DMRS图样或第一DMRS端口号，从多个数据分布方式中确定与该第一DMRS图样或第一DMRS端口号对应的数据分布方式。例如，网络设备和终端设备可以约定端口号x1-y1表示该端口号对应时域集中的数据分布方式，端口号x2-y2表示该端口号对应时域分散的数据分布方式，但本申请实施例对此不作限定。
应理解，上述DMRS的属性除了可以是DMRS的图样或DMRS的端口号之外，还可以是DMRS的扰码或正交序列，本申请实施例对此不作限定。
在一种可能实现的方式中，所述终端设备可根据所述网络设备发送的数据分布方式指示信息确定所述数据分布方式，所述数据分布方式指示信息用于指示所述网络设备所采用的数据分布方式，可以是DCI、RRC信令、MAC层CE等等，本申请实施例对此不作限定。
在一种可能实现的方式中，所述终端设备可根据帧结构确定所述数据分布方式。所述帧结构用于指示解调结果需要在当前资源单元(具体可为当前帧)反馈或不需要在当前资源单元反馈。若解调结果需要在当前资源单元反馈，则对应的的数据分布方式为时域集中分布方式；若不需要在当前资源单元反馈，则对应的数据分布方式为时域分散分布方式。

在图5所描述的实施例中，网络设备对传输数据进行交织处理，或按照映射顺序进行映射处理，或对传输数据进行交织处理并按照映射顺序进行映射处理，针对不同的处理方式可以得到不同的数据分布方式，从而可以实现集中分布和分散分布的数据分布方式，可以适用于具有多种应用场景的系统中。
作为一个可选的实施例，所述网络设备可在进行层映射之前对传输数据进行交织处理，即可在图1所示的调制模块与层映射模块之间增加一个交织模块，该交织模块用于实现频域交织、时域交织、时频交织，具体实现哪种交织视具体情况而定。
具体地，d(m),m＝0,...,M-1，d(m)表示层映射模块之前码字内的各个调制符号，m表示调制符号在码字内的序号。交织过程如下：

作为一个可选的实施例，所述网络设备可在进行资源元素映射时对传输数据进行交织处理，即对图1所示的资源元素映射模块进行改进，使其不仅能够实现时频映射的功能，还能实现频域交织、时域交织和时频交织的功能。此时，可以不限定交织与时频映射的先后顺序。
作为一个可选的实施例，所述网络设备可在进行资源元素映射时按照时域映射在频域映射之前的映射顺序对传输数据进行映射处理，即可对图1所示的资源元素映射模块进行改进，使其不仅能够实现LTE系统中先频域映射再时域映射的映射顺序，还可以实现先时域映射再频域映射的映射顺序。
具体地，每个天线上的复数符号映射到调度资源(k，l)上。映射过程中除去物理广播信道(Physical Broadcast Channel，PBCH)、同步等PDSCH/物理上行共享信道(Physical Uplink Shared Channel，PUSCH)不可用的资源。

作为一个可选的实施例，所述网络设备可配置如图6a-图6d所示的四种DMRS的图样示例图。在解调结果需要在当前帧反馈的情况下，所述网络设备可以采用对应的DMRS的属性，该DMRS的属性可以对应时域集中分布方式，可配置图6a和图6b所示的DMRS的图样示例图，为解调结果需要在本帧反馈的DMRS的图样的示例图，图6a和图6b所示的DMRS的图样对应的数据分布方式可以为时域集中分布方式。反之，在解调结果不需要在当前帧反馈的情况下，所述网络设备可以采用对应的DMRS的属性，该DMRS的属性可以对应时域分散分布方式，可配置图6c和图6d所示的DMRS的图样示例图，为解调结果不需要在本帧反馈的DMRS的图样示例图，图6c和图6d所示的DMRS pattern对应的数据分布方式均可以为时域集中方式。
在一种可能实现的方式中，在DMRS的图样为DMRS占用一个时域符号的情况下，该DMRS的图样对应时域集中分布方式。
在一种可能实现的方式中，在DMRS的图样为DMRS占用至少两个时域符号的情况下，若DMRS占用的任意两个时域符号之间不存在数据的传输，则该DMRS的图样对应时域集中分布方式；若DMRS占用的时域符号之间存在至少两个时域符号之间存在数据的传输，则该DMRS的图样对应时域分散分布方式。
具体地，所述网络设备在DMRS的图样为DMRS占用一个时域符号的情况下，该DMRS的图样对应时域集中分布方式；在DMRS的图样为DMRS占用至少两个时域符号的情况下，若该DMRS的图样为DMRS占用的任意两个时域符号之间不存在数据的传输，即任意两个DMRS的时域符号之间不存在数据的传输，那么该DMRS的图样可以对应时域集中分布方式，图6a为DMRS的传输在数据传输之前的一个DMRS的图样示例图，图6a所示的DMRS的图样对应的数据分布方式可以为时域集中分布方式；若该DMRS占用的时域符号之间存在至少两个时域符号之间存在数据的传输，即存在两个DMRS的时域符号之间存在数据的传输，那么该DMRS的图样可以对应的数据分布方式可以为时域分散分布方式，图6b-图6c的DMRS的图样示例图均存在DMRS的传输在数据传输之后，因此，这三种DMRS的图样对应的数据分布方式均可以为时域分散分布方式。
综上所述，数据分布方式与DMRS的图样之间的对应关系可以采用以下两种不同的方式。
方式一：在适用于任意两个DMRS的传输之间不存在数据的传输的DMRS的图样(图6a)下，采用时域集中分布方式；在适用于存在两个DMRS的传输之间存在数据的传输(图6b、图6c以及图6d)下，采用时域分散分布方式。
方式二：在适用于解调结果需要在当前资源单元反馈的DMRS的图样(图6a和图6b)下，采用时域集中分布方式；在适用于解调结果不需要在当前资源单元反馈的DMRS的图样(图6c和图6d)下，采用时域分散分布方式。
应理解，采用何种方式取决于应用场景或者终端设备的业务需求，由网络设备进行配置，本申请实施例对此不作限定。
