Description

信号配置、发送方法及装置
本申请要求在2017年09月12日提交中国专利局、申请号为201710819476.1的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及通信领域，例如涉及一种信号配置、发送方法及装置。
背景技术
在相关技术的新无线(New Radio，NR)中，上行传输支持两种传输波形，分别为DFT-S-OFDM和CP-OFDM。前者就是长期演进技术(Long Term Evolution，LTE)中的上行单载波频分多址(Signal-carrier Frequency-Division Multiple Access，SC-FDMA)，后者就是长期演进(Long-Term Evolution，LTE)下行的波形，通常也简称正交频分复用(Orthogonal Frequency-Division Multiplexing，OFDM)或正交频分多址(Orthogonal Frequency-Division Multiple Access，OFDMA)。DFT-S-OFDM有较小的峰均比，CP-OFDM有更好的传输性能。
在NR中，上行支持两种传输方式，一种方式是基于码本(Code Book，CB)的传输，另外一种方式是不基于码本的传输。分别称为基于码本传输(CB based transmission)和不基于码本的传输(Non CB based transmission)。
一般来说，为了更好的传输性能，动态的进行切换会有明显的增益，切换包括：在DFT-S-OFDMA和CP-OFDM之间切换，在CB based传输和Non-CB based传输之间切换，在不同的SRIs数目之间切换。
但是，这会明显的增加物理层控制信令开销，比如：Waveform的切换需要1比特(bit)CB based传输和Non-CB based传输切换需要则外增加1比特，而在不同的SRIs数目间切换，如果支持最大2个SRIs需要1比特，支持最大4个SRIs需要2比特，支持最大8个SRIs需要3比特。物理层信令开销是极其宝贵的资源，因为控制信道的鲁棒性要求很高，一般实际传输时码率很低，调制编码方式也是低阶，占用的实际传输资源是很多的。如果存在大量的UE，开销浪费会很严重。
针对相关技术中存在的上述问题，目前尚未发现有效的解决方案。

需要说明的是，本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在NR中，CB based transmission需要收发端约定码本。基站会指配使用的传输层数r以及该层数下对应的码字W(i)，如果有信道探测参考信号(Sounding Reference Signal，SRS)的选择，还会指示参考探测导频指示(Sounding Reference Indicator，SRI)的信息，图1是本公开相关技术中基于码本的传输的示意图。
该方式中终端会发送SRS，基站在SRS的资源中选出一些资源作为上行数据或控制传输的参考。对于CB based transmission，基站还需要指示层数指示(TRI)和预编码指示(Transmitted Precoding Matrix Indicator，TPMI).在SRS预编码的基础上再进行预编码并用于数据或控制传输。这里预编码也可以用于端口的选择。
Non-CB based transmission不需要收发端约定码本，基站可以发送TRI指示传输层数r，也可以不指示，不指示时默认r与SRS resource中的端口数目相等。终端采用指示的SRS resource来确定数据的传输，一般使用与指示的SRS 相同的预编码方式，不需要进行额外的预编码，图2是本公开不基于码本的传输的示意图。
有些终端可能会存在多个panel或者设置多个不同方面的射频波束，此时可以指示多个SRIs，分别对应不同天线组或者波束的传输。不同的SRI可以对应相同或不同的传输层。在Non-CB based传输和CB based传输中均可以指示多个SRIs。

实施例3
本实施例是根据本公开的应用实施例，用于结合具体的实施方式对本申请 进行详细说明。
本实施例的联合编码技术中，波形指示信息(Waveform indication，WI)的动态切换主要利用以下的特性来减小开销：可以针对不同的码字，分别考虑支持不同的可选Waveform类型集合。比如一些码字会破坏峰均比，即使采用DFT-S-OFDM也不能控制峰均比，因此不会与其结合。
可以针对不同的Rank/layer的取值情况，分别考虑支持的可选Waveform类型集合。
可以针对不同的资源区域，分别考虑支持不同的可选Waveform类型集合。采用相同的waveform会提高上行多用户多入多出(Multiple-User Multiple Input Multiple Output，MU-MIMO)性能，因此可以划分资源区域，然后分别设置对应的waveform类型。
可以针对不同的SRS resource，分别考虑支持可选Waveform类型集合。有一些SRS的传输本身已经进行了一些预编码，可能存在峰均比问题，即使采用DFT-S-OFDM也不能控制峰均比，因此不会与其结合。
Waveform类型集合包括“DFT-S-OFDM”、“CP-OFDM”“CP-OFDM和DFT-S-OFDM”。
实例：RI和PMI指示与Waveform指示联合编码如表1所示。
表1
Figure PCTCN2018105154-appb-000001
由于高Rank情况一般都是信噪比高的小区中心用户，峰均比问题不明显，此时不支持DFT-S-OFDM也不会有明显的性能损失。另外，在Rank1中码字05-08只支持CP-OFDM.这部分码字对应的预编码会破坏天线的峰均比，即使支 持DFT-S-OFDMA也不能有很好的降低峰均比效果。上面的实施例中，可以联合编码为32个状态，根据状态位不但可以获知RI和PMI信息还可以获知waveform信息。通过上述联合编码方式，避免一些实际情况较难出现的联合情况，可以有效的降低开销。在本实施例中，独立编码开销：5比特(RI+PMI)+1比特(WI)，而联合编码开销：5比特(RI+PMI+WI)。WI表示波形指示信息waveform indication。
还有一些例子如下：DFT-S-OFDM和CP-OFDM对应不同的Rank1码字且没有交集。也可以考虑有部分交集的情况。比如码字01-02对应两种waveform，码字03-04对应DFT-S-OFDM，码字05-06对应CP-OFDM，如表2所示。
表2
Figure PCTCN2018105154-appb-000002
Waveform也可以与SRI来联合编码如表3所示。
表3
序号(Rank)/层数(layer)1
SRI＝01，DFT-S-OFDM
SRI＝02，DFT-S-OFDM
SRI＝03，CP-OFDM
SRI＝04，CP-OFDM
Waveform还可以与资源区域的指示联合编码、或者与DMRS和或PTRS的配置进行联合编码、或者与MCS进行联合编码、功率控制指示参数联合编码。
在一实施例中，上面的方式是可以进行结合的，并且具体的联合编码的方式还有多种其它的考虑，可以根据具体的网络环境，终端的配置来确定如何进行联合编码。编码的比特数目也不局限于固定的编码比特数目。由于对一些不会经常出现的联合的情况、或没有需要的联合情况针对性进行了限制，开销会减小，但对实际性能影响不大。这种方法还可以有效的降低终端复杂度。
Non-CB based传输和CB based传输动态切换主要利用以下几种特性来减小开销。与PMI进行联合编码：将Non-CB based做成一种无需预编码指示状态。表示此时不需要使用预编码。也可以将该预编码其理解为一个单位阵或者单位阵的前r列。r为layer/rank的取值，如表4所示：
表4
Figure PCTCN2018105154-appb-000003
这种方式无需额外的1比特来指示是哪种类型的传输，在不增加开销(3比特)的情况下，实现了动态的切换。无码字指示也可以不区分layer1还是layer2。此时默认layer为SRS port数目。
与SRI联合编码：如果有SRI的指示，可以联合编码如下表5所示：
表5
SRI＝01，CB based
SRI＝02，CB based
SRI＝03，Non-CB based
SRI＝04，Non-CB based
也可以将SRI，TPMI，以及CB/Non-CB指示一起联合编码，如表6所示：
表6
SRI＝1 SRI＝2 SRI＝3 SRI＝4
码字01 码字01 码字01 码字01
码字02 码字02 码字02 码字02
码字03 无需预编码指示 码字03 无需预编码指示
码字04   码字04  
无需预编码指示   无需预编码指示  
这里一共4比特，而如果独立编码则需要2+2+1＝5比特。
与资源指示信息联合编码，如表7所示：
表7
资源区域1，CB based
资源区域2，Non-CB based
这样可以将2比特开销缩减到1比特。由于资源区域1本身不适合做Non-CB based传输，实际上没有什么能量损失。
也可以是与其它信息联合编码，例如，CB based时TMPI为子带的结合。
SRI数目的动态切换主要利用以下的特性来减小开销：不同SRI数目之间联合编码，对多个SRI的组合进行限制，如表8所示：
表8
1个SIR 2个SRI 3个SRI
SRI＝1 SRI＝1，3 SRI＝1，3，5
SRI＝2 SRI＝1，4 SRI＝2，4，6
SRI＝3 SRI＝2，3  
SRI＝4 SRI＝2，4  
这种方式避免了SRI＝1，2，SRI＝3，4、以及SRI＝2，3，5，1，4，6等情况，减小了开销。实际上基站已经预先判断出这些情况下干扰较大一般也不太可能会进行这种选择，所以不会影响性能。如果SRS resource更多，开销节约会更明显。
本实施例的隐含指示方式中，可以利用以下的一些方式来指示Waveform，包括：
下行控制信道格式(DCI format)、控制信道的解调导频序列、下行控制信道(Downlink Control Information，DCI)的加扰方式、以及DCI的传输位置。
DCI format对应表9，DCI的加扰方式对应表10：
表9
DCI Format 波形(Waveform)
A DFT-S-OFDM
B CP-OFDM
表10
DCI加扰方式 波形(Waveform)
扰码1 DFT-S-OFDM
扰码2 CP-OFDM
可以利用以下的一些方式来指示Non CB还是CB传输，包括：
DCI format、控制信道的解调导频序列、DCI的加扰方式；DCI的传输位置，DCI format对应表11，DCI的加扰方式对应表12：
表11
DCI Format 波形(Waveform)
C Non CB
B CB
表12
DCI加扰方式 波形(Waveform)
扰码1 Non CB
扰码2 CB
本实施例方案的有益效果是节约了开销，信令开销的利用率更高。
