Description

一种数据传输的方法及设备
本申请要求于2017年7月20日提交中国专利局、申请号为201710596241.0、发明名称为“一种数据传输的方法及设备”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，具体涉及一种数据传输的方法及设备。
背景技术
在长期演进(英文全称：long term evolution，英文缩写：LTE)系统中，发射机物理(英文全称：physical，英文缩写：PHY)层在接收到来自媒体访问控制(英文全称：medium access control，英文缩写：MAC)层的一个传输块(英文全称：transport block，英文缩写：TB)之后，经过CRC添加、信道编码、速率匹配、码块级联等传输块处理环节之后，产生一串比特数据，该比特数据在LTE系统中称为码字(英文全称：codeword，英文缩写：CW)。
在当前LTE系统中，最多支持2个传输块的同时传输，码字的数量等于传输块的数量。如图1所示，以LTE的下行传输为例，码字经过加扰、调制、层映射、预编码、资源映射、正交频分复用(英文全称：orthogonal frequency division multiplexing，英文缩写：OFDM)信号生成等物理信道处理环节之后，产生各天线端口上待发送的信号。
在终端接收或发送数据之前，需要从网络接收调度信令，以便终端获知应当在什么时频资源位置，采用什么配置，来接收或发送数据。
在LTE系统中，动态调度等信令承载于物理下行控制信道(英文全称：physical downlink control channel，英文缩写：PDCCH)中，其信令内容为下行控制信息(英文全称：downlink control information，英文缩写：DCI)，其信令内容的格式(format)由DCI format规定。LTE系统中定义了多种DCI format，多种DCI format可以分别支持不同类型的传输，比如有的DCI format可以支持下行(英文全称：downlink，英文缩写：DL)传输、有的DCI format可以上行(英文全称：uplink，英文缩写：UL)传输，有的DCI format可以支持单码字传输、有的DCI format可以支持双码字传输等。
例如，LTE系统中的DCI format 2C，支持DL传输的多层空间复用，可以支持双码字和单码字的传输，DCI format 2C中包含了以下字段：
-第一字段(承载指示字段)：Carrier indicator–1bit；
-第二字段(天线端口信息字段)：Antenna port(s),scrambling identity and number of layers–3bit；
第1第三字段(传输块1配置信息字段)：
-调制与编码的组合(Modulation and coding scheme)–5bits；
-新数据指示(New data indicator)–1bit；
-冗余版本(Redundancy version)–2bits；
第2第三字段(传输块2配置信息字段)：
-调制与编码的组合(Modulation and coding scheme)–5bits；
-新数据指示(New data indicator)–1bit；
-冗余版本(Redundancy version)–2bits；
由以上DCI格式的描述可见，现有技术中，DCI格式中各字段的长度都是固定的，即使上述字段的长度随单码字或者双码字而不同，但为了便于终端检测，无论是单码字还是双码字的DCI format也必须按照单码字和双码字中的最大长度来设计，由此可见，现有技术中在数据传输过程中的DCI format的设置方式不灵活。
发明内容
为例解决现有技术中在数据传输过程中控制信息的格式设置不灵活的问题，本申请实施例提供一种数据传输的方法，可以依据待传输的传输块的数量来灵活确定控制信息中用于指示天线端口配置信息的第二字段的长度和用于指示传输块的配置信息的第三字段的数量，从而提高了控制信息格式设置的灵活度，并在多种场景下节省了控制信息的信令开销。本申请实施例还提供了相应的设备。

本申请实施例提供一种数据传输的方法，可以依据待传输的传输块的数量来灵活确定控制信息中用于指示天线端口配置信息的第二字段的长度和用于指示传输块的配置信息的第三字段的数量，从而提高了控制信息格式设置的灵活度，并在多种场景下节省了控制信息的信令开销。本申请实施例还提供了相应的设备及系统。以下分别进行详细说明。
图2为本申请实施例中数据传输的系统的一实施例示意图。
如图2所示，该数据传输的系统包括网络设备和终端，该网络设备可以是基站，在LTE系统中，基站可以称为演进基站eNobe，该网络设备也可以是无线接入网络(radio access network，RAN)设备，当然，该网络设备还可以其他可以执行相应控制信息配置功能的设备。终端可以包括手机和平板电脑等根据控制信息进行数据传输的设备。
在图2所示的数据传输的系统中，无论是数据的上行传输还是下行传输，都由网络设备确定控制信息，并向终端发送该控制信息，从而使终端完成数据的接收或发送。
结合图2所示的数据传输的系统，下面结合图3介绍本申请实施例中的数据传输的方法。
如图3所示，本申请实施例提供的数据传输的方法的一实施例包括：
101、网络设备确定控制信息。
所述控制信息包括第一字段、第二字段和至少一个第三字段；其中，所述第一字段用于指示待传输的传输块的数量；所述第二字段包括天线端口配置信息，所述第二字段的长度与所述传输块的数量相关；所述第三字段包括所述传输块的配置信息，所述第三字段的数量与所述传输块的数量相关。
第一字段所指示的可以是TB的数量、TB的数量的标识、或者其他可以用于确定TB的数量的信息，例如：该可以用于确定TB的数量的信息可以是码字数，可以预先约定TB的数量与CW的数量之间的映射关系，这样可以根据CW的数量确定TB的数据，当然，该第一字段所指示的还可以是其他可以用于确定TB的数量的信息。
第二字段的长度，也就是比特数可以根据TB的数量来确定。
第三字段的数量与TB的数量对应，通常，一个TB会对应一个第三字段，第三字段通常会包括调制与编码的组合、新数据指示和冗余版本三部分，通常一个第三字段的长度为8bits。
第二字段的长度根据TB的数量确定，第三字段的数量可以根据TB的数量确定。
当所述第一字段指示的所述传输块的数量为第一数值时，所述第二字段的长度为第一长度，所述第三字段的数量为所述第一数值；
当所述第一字段指示的所述传输块的数量为第二数值时，所述第二字段的长度小于所述第一长度，所述第三字段的数量为所述第二数值，所述第二数值大于所述第一数值。
例如：若TB的数量为第一数值时，该第一数值的取值可以为1，则第二字段的长度可以是4bits，第三字段的数量可以一个，若TB的数量为第二数值时，该第二数值的取值可以为2，则第二字段的长度可以是1bit，第三字段的数量可以是两个，若TB的数量是3或者其他数值，则第二字段的长度可以根据该数值确定，第三字段的数量可以与该TB的数量对应 确定。
因为通常情况下一个TB对应一个码子，所以一个TB可以称为单码字，两个TB可以称为双码字。
102、网络设备向终端发送控制信息。
103、终端接收到网络设备发送的控制信息后，根据该控制信息与网络设备进行数据传输。
与现有技术相比，本申请实施例提供的数据传输的方法，可以依据待传输的传输块的数量来灵活确定控制信息中用于指示天线端口配置信息的第二字段的长度和用于指示传输块的配置信息的第三字段的数量，从而提高了控制信息格式设置的灵活度，并在多种场景下节省了控制信息的信令开销。
传输系统中通常包括多层，在多层传输中，第二字段的信息包括了所映射的层和天线端口号。数据传输过程中需要根据第二字段上的层信息和天线端口号映射到相应的层，并由相应的天线端口号传输。
以6层传输层为例，也就是最大层数为6，通常4层及4层以下都采用单码字传输，5层和6层采用双码字传输。这样，单码字传输时为了记录各个层和天线端口号，单码字传输需要4bits，双码字因为只有5层和6层，则只需要1bit。
单码字的第二字段的信息可以参阅表1进行理解。
表1：单码字的第二字段
Value Message
0 1layer,port0
1 1layer,port1
2 1layer,port2
3 1layer,port3
4 1layer,port4
5 1layer,port5
6 2layer,port 0-1
7 2layer,port 2-3
8 2layer,port 4-5
9 3layer,port 0-2
10 3layer,port 3-5
11 4layer,port 0-3
12 Reserved
… …
15 Reserved
表1中，Value为第二字段的值，Message为第二字段的值所对应的层数和天线端口信息。Layer为层，port为天线端口，Reserved为保留字段，后续可以根据需求在Reserved 字段配置相应的层和天线端口信息。
双码字的第二字段的信息可以参阅表2进行理解。
表2：双码字的第二字段
Value Message
0 5layer,port 0-4(SU)
1 6layer,port 0-5(SU)
表2中，Value为第二字段的值，Message为第二字段的值所对应的层数和天线端口信息。Layer为层，port为天线端口，Reserved为保留字段，后续可以根据需求在Reserved字段配置相应的层和天线端口信息。
当然，上述表1和表2中第二字段所指示的天线端口号以及层映射，也可以只使用一个表格来表示，如表3所示：
表3：
Figure PCTCN2018085811-appb-000001
表3中，One Codeword为单码字，Two Codewords为双码字，Codeword 0 enabled表示码字0可被使用，Codeword 1disabled表示码字1不可以使用，另外表3中的其他信息可参阅表1和表2部分的解释进行理解。
当然，上述表1至表3的内容只是以最大层数是6层为例进行的说明，实际上，本申请实施例中对最大传输层数不做限制，无论是多少个传输层都可以采用本申请中的思想， 即：第二字段的长度可以根据TB的数量来确定，第三字段的数量可以根据TB的数量来确定。
第一字段、第二字段和第三字段在控制信息中可以连续出现，也可以不连续出现；可以按任意次序出现。
当第一字段指示的传输块数量为1时，控制信息中不包含第2第三字段；当第一字段指示的传输块数量为2时，控制信息中包含第2第三字段。
本申请实施例所提供的方案，当有一个传输块时，
当第一字段指示有1个传输块时，第一字段的长度为1比特，第二字段的长度为4比特，第三字段的数量为1(即没有第2第三字段)，长度为8比特，这三种字段的总长度为1+4+8＝13bits。
当第一字段指示有2个传输块时，此时，第一字段的长度为1比特，第二字段的长度为1比特，第三字段的数量为2，长度为2×8＝16比特，这三种字段的总长度为1+1+16＝18bits。
因此，这三种字段的最大总长度为18比特，需要在该DCI信令中占用18比特开销。相比于现有技术中的20bits的信令开销，节省了2bits的信令开销，最重要的是，本申请实施例所提供的方案实现了对第二字段的长度和第三字段的数量根据TB需求的灵活确定。
该处只是以6层传输层为例进行介绍，实际上，不同传输块数的天线端口配置信息的长度差异较大，能够根据传输块的数量灵活确定第二字段的长度，在很多场景下都可以节省信令开销。
以上所描述的第二字段的长度可以根据TB的数量确定，实际上，不限于只根据TB的数量来确定第二字段的长度。还在第一字段的基础上，结合高层参数来确定第二字段的长度。该高层参数可以通过无线资源控制(英文全称：Radio Resource Control，英文缩写：RRC)信令进行传输。
例如：在最大传输层数为6层的场景中，若第一字段指示传输块的数量为1，高层参数的取值为一预先设定值，例如该预先设定值为非0时，第二字段的长度可以根据表1来确定。若第一字段指示传输块的数量为1，高层参数的取值为另一预先设定值，例如：该另一预先设定值0时，第二字段的长度可以根据表4来确定。
表4:单码字的天线端口及层数(3比特)
Value Message
0 1layer,port0
1 1layer,port1
2 1layer,port2
3 1layer,port3
4 2layer,port 0-1
5 2layer,port 2-3
6 3layer,port 0-2
7 4layer,port 0-3
表4中各参数的含义可以参阅表1和表2部分的解释进行理解。
在另一示例中，还可以根据传输块的数量和高层参数，以及预设的公式来确定第二字段的长度。
例如：通过如下公式来确定第二字段的长度：
第二字段的长度＝3-2N TB+Q；
其中，N TB为传输块的数量，Q为所述高层参数。
在另一示例中，还可以通过传输块数量的指示flag_TB来确定第二字段的长度：
第二字段的长度＝5-2flag_TB+Q
其中，flag_TB为所述传输块的数量的指示标识，Q为所述高层参数。
当然，上述两个公式只是举例说明，还可以通过其他形式的公式来确定第二字段的长度。
在另一示例中，还可以通过码字数量和高层参数，以及预设的表格来确定第二字段的长度。
预设的表格可以参阅表5进行理解，如表5所示：
表5：高层参数与第二字段的长度的映射表
Figure PCTCN2018085811-appb-000002
其中，dmrs-table-index为高层参数，N b为第二字段的长度，由表5可见，依据单码字或者双码字的情况，就可以根据高层参数的取值确定第二字段N b的长度。表5中的其余参数可参阅表1和表2部分的解释进行理解。
表中reserved是保留值，当前暂不定义，可以根据使用需求再定义。N b＝0时，第二字段的长度为零，即在信令中不传输第二字段。
另一个示例中，还可以根据码字数量，一个DMRS图样配置参数dmrs-pattern和一个高层参数dmrs-tableAlt，通过预设的另一表格来确定第二字段的长度。
预设的另一表格可以参阅表6进行理解，如表6所示：
表6:不同图样配置参数下高层参数与第二字段的长度的映射表
Figure PCTCN2018085811-appb-000003
其中，dmrs-pattern为图样配置参数，dmrs-tableAlt为高层参数，N b为第二字段的长度，由表6可见，根据图样配置参数以及单码字或者双码字的情况，就可以根据高层参数的取值确定第二字段N b的长度。
表6中“-”表示没有定义。在该例子中，高层参数dmrs-tableAlt的取值范围根据图样配置参数dmrs-pattern的配置。当dmrs-pattern＝0时，dmrs-tableAlt有4种取值，可以用2比特指示；当dmrs-pattern＝1时，dmrs-tableAlt有2种取值，可以用1比特指示。
确定第二字段长度所用的表格，可以是如表6这样的一个表格，也可以是分别对应于dmrs-pattern＝0、dmrs-pattern＝1的两个表格，也可以是分别对应于单码字、双码字的两个表格，也可以是分别对应于dmrs-pattern＝0单码字、dmrs-pattern＝0双码字、dmrs-pattern＝1单码字、dmrs-pattern＝1双码字的四个表格，也可以是对应于其它多种参数取值的多个表格。例如：表7所示的dmrs-pattern＝0单码字、dmrs-pattern＝0双码字的表格，以及表8所示的dmrs-pattern＝1单码字、dmrs-pattern＝1双码字的表格。
表7:高层参数与第二字段的长度的映射表(dmrs-pattern＝0)
Figure PCTCN2018085811-appb-000004
表8：高层参数与第二字段的长度的映射表(dmrs-pattern＝1)
Figure PCTCN2018085811-appb-000005
本申请实施例中，当所述第一字段指示所述传输块的数量为1时，所述控制信息中还包括第四字段，所述第四字段上的信息用于指示在数据传输时被使用的码字，所述码字为 所述传输块在物理层的表现形式。
例如：针对单码字的传输情况，可以选择码字1对应的信道，也可以选择码字2对应的信道，当码字1和码字2对应的信道条件会随时间发生不同变化，有时码字1的信道条件更好，有时码字2的信道条件更好，采用这种方法，可以选择利用信道条件较好的码字，来传输一个传输块的数量，从而提升了数据传输的效率。
第四字段中的信息可以参阅表9进行理解，如表9所示：
表9:传输块-码字映射
Codeword indicator Codeword
0 Codeword 1
1 Codeword 2
当第四字段上的码字指示信息(Codeword indicator)为0时，则确定选择码字1进行数据传输，当第四字段上的码字指示信息(Codeword indicator)为1时，则确定选择码字2进行数据传输。当然，映射关系可以调整，不限于表9中的一种方式。
单码字传输时，若选择码字1，则控制信息中只需要包括第1第三字段，可以不包括第2第三字段，当选择码字2时，则控制信息中只需要包括第2第三字段，则可以不包括第1第三字段。
当不同码字数量的天线端口配置的长度差异较大时，本申请技术方案可以有效地节省信令开销。反之，当不同码字数量的天线端口配置的长度差异较小时，在调度信令中引入第一字段，就不一定能够节省信令开销。
因此，如图4所示，本申请实施例提供的数据传输的方法的另一实施例包括：
111、网络设备确定控制信息和所述控制信息的配置参数，所述配置参数用于配置所述控制信息的格式。
当所述配置参数的取值为第一配置值时，所述控制信息包括第一字段、第二字段和至少一个第三字段；其中，所述第一字段包括用于指示待传输的传输块的数量的第一字段；所述第二字段包括天线端口配置信息，所述第二字段的长度与所述传输块的数量相关；所述第三字段包括所述传输块的配置信息，所述第三字段的数量与所述传输块的数量相关。
当所述配置参数的取值为第二配置值时，所述控制信息包括第二字段和至少一个第三字段；所述第二字段的长度和所述第三字段的数量与所述格式相关。
第二字段的长度与所述传输块的数量相关即第二字段的长度可以根据传输块的数量确定。
第三字段的数量与所述传输块的数量相关即第三字段的数量可以根据传输块的数量确定。
格式也可以称为结构。
112、网络设备向终端发送所述控制信息和所述配置参数。
113、网络设备根据所述控制信息和所述配置参数，与所述终端进行数据传输。
本申请实施例提供的是第一字段的开关方案，也就是有条件地启用第一字段，有利于保证在不同条件下，都能够取得信令长度优化的效果。
根据配置参数(比如RRC信令中携带的参数)flag-TB-number-indication，确定调度信令中是否包含第一字段：
当网络设备没有配置控制信息的格式，也就是没有为控制信息的格式设置配置参数flag-TB-number-indication，或者网络设备设置了配置参数，并将配置参数的取值设置为预设值，例如：该预设值为0时，则不包含第一字段，可以根据该格式的配置参数确定第二字段的长度和第三子段的数量。
当配置参数flag-TB-number-indication配置的值大于0时，调度信令中包含第一字段，此时可以直接根据第一字段的指示，确定传输块的数量。
以上所描述的是单码字或者双码字的示例，实际上，本申请实施例也适用于多码字的情况，例如：第一字段的长度可以为2，则第一字段中的数量第一字段与传输块的数量的对应关系可以参阅表10进行理解，如表10所示：
表10：多码字第一字段映射关系
Figure PCTCN2018085811-appb-000006
TB number indicator为传输块的数量指示，Number of Transport Blocks为传输块的数量。当第一字段指示的传输块数量为1时，信令中不包含第2个第三字段和第3个第三字段；当第一字段指示的传输块数量为2时，信令中不包含第3个第三字段。
以上表1至表10中所涉及到的相关参数的含义都可以互相参照理解，同一参数在不同表格中的含义是相同的。
