Description

发送方式确定方法、通信节点和计算机存储介质
本申请基于申请号为201710014926.X、申请日为2017年01月09日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及无线通信领域，尤其涉及一种发送方式确定方法及通信节点和计算机存储介质。
背景技术
在相关技术中，在长期演进(Long Term Evolution，简称为LTE)中，物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)用于承载上、下行调度信息，以及上行功率控制信息。下行控制信息(Downlink Control Information，简称为DCI)格式(format)分为DCI format 0、1、1A、1B、1C、1D、2、2A、3，3A等，后面演进至LTE-A Release 12(LTE-A版本12)中又增加了DCI format 2B、2C、2D以支持多种不同的应用和传输模式。演进型基站(e-Node-B，简称为eNB)可以通过下行控制信息配置用户设备(User Equipment，简称为UE)，或者UE接受高层(higher layers)的配置，也称为通过高层信令来配置UE。用户设备又可以称之为终端；
随着通信技术的发展，数据业务需求量不断增加，可用的低频载波也已经非常稀缺，由此，基于还未充分利用的高频(30～300GHz)载波通信成为解决未来高速数据通信的重要通信手段之一。高频载波通信的可用带宽很大，可以提供有效的高速数据通信。但是，高频载波通信面临的一个很大的技术挑战就是：相对低频信号，高频信号在空间的衰落非常大，虽 然会导致高频信号在室外的通信出现了空间的衰落损耗问题，但是由于其波长的减小，通常可以使用更多的天线，从而可以基于波束进行通信以补偿在空间的衰落损耗。
但是，当天线数增多时，由于此时需要每个天线都有一套射频链路，基于数字波束成型也带来了增加成本和功率损耗的问题。因此，目前的研究中比较倾向于混合波束赋形，即射频波束和数字波束共同形成最终的波束。
在新的无线接入技术(New Radio Access Technology)的研究中，高频通信***除了第一通信节点会配置大量的天线形成下行传输波束以补偿高频通信的空间衰落，用户第二通信节点同样也会配置大量的天线形成上行传输波束。在现有的研究中，第二通信节点可以使用两种不同的传输波形，分别为离散傅里叶变换扩频的正交频分复用(DFT-S-OFDM)和循环前缀正交频分复用(CP-OFDM)，但是具体实现时，这两种传输方式的实际传输效果并没有达到期望的理想效果。
发明内容
有鉴于此，本发明实施例期望提供一种发送方式确定方法及通信节点和计算机存储介质，以至少部分解决不同的频分复用的传输效果不够好的问题。。
为达到上述目的，本发明的技术方案是这样实现的：
本发明实施例第一方面提供一种发送方式确定方法，包括：
第一通信节点确定第二通信节点发送信息所使用的发送方式，并将所述发送方式通过信令指示给第二通信节点；
或者，

具体实施方式
以下结合说明书附图及具体实施例对本发明的技术方案做进一步的详细阐述，应当理解，以下所说明的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
如图1所示，本实施例提供一种发送方式确定方法，包括：
步骤S110：第一通信节点确定第二通信节点发送信息所使用的发送方式；
步骤S120：将所述发送方式通过信令指示给第二通信节点；
如图2所示，本实施例还提供另一种发送方式确定方法，包括：
步骤S200：第一通信节点和第二通信节点双方预定义第二通信节点发送信息所使用的发送方式，其中，所述信息包括业务数据和/或控制信息。
在本发明实施例中，第一通信节点可以为宏小区的基站、小小区(small cell)的基站或传输节点、高频通信***中的发送节点、物联网***中的发送节点等发送和控制终端的设备节点。第二通信节点可以为用户终端(UE)、手机、便携设备、汽车等通信***中的接收节点。当然，所述基站、发送节点等设备节点可作为所述第二通信节点，UE可称为第一通信节点。总之，所述第一通信节点可为发送指示发送方式的信令的发送节点，所述第二通信节点可为接收所述信令的接收节点。
对于传输波形或发送方式，可包括：DFT-S-OFDM及CP-OFDM；其中，所述DFT-S-OFDM又可称为单载波频分多址、单载波的传输波形；所述CP-OFDM又可称为正交频分多址、多载波的传输波形。
在本实施例中当所述第一通信节点和第二通信节点之间有一个为基站，另一个为UE时，所述发送方式为上行信息的发送方式。则所述上行信息包括上行业务数据和/或上行控制信息。
在一些实施例中，所述第一通信节点和第二通信节点在确定发送方式 之前，双方通过信息协商或按照通信协议预先定义发送方式。
如图3所示，所述方法还包括：
步骤S100：在所述第一通信节点确定所述发送方式之前，接收所述第二通信节点上报的所述第二通信节点建议的发送方式或所述第二通信节点的功率放大器PA的相关信息，其中，所述相关信息至少包括以下之一：功率放大器的饱和区起始电压与静态工作点的电压之间的第一差值、所述功率放大器的饱和区起始电流与静态工作点的电流之间的第二差值、所述功率放大器的静态工作点所处的区间；
所述步骤S110可包括：
根据所述建议的发送方式或所述PA的相关信息，确定所述发送方式。这里的建议的发送方式，为所述第二通信节点想要的发送方式，所述第一通信节点可以直接选择第二通信节点建议的发送方式，作为第二通信节点的上行发送的最终发送方式。所述第二通信节点确定所述建议的发送方式，也可以根据自身的PA的相关信息来确定。当所述第一差值大于第一门槛值时，则采用CP-OFDM，否则可以采用DFT-S-OFDM；或，当所述第二差值大于第二门槛值时，则采用CP-OFDM，否则可以采用DFT-S-OFDM。
这里的第一门槛值和所述第二门槛值都可为预设值，或根据预设函数关系计算得到的。在本实施例中所述第一门槛值和第二门槛值，均可与第二通信节点向第一通信节点的数据发送的峰均比或数据发送功率的立方度量(Cubic Metric，CM)值相关。
在还有些实施例中，所述功率放大器在线性放大区间的最小工作信号为E，最大工作信号为F；当所述最小工作信号为最小工作电压时，所述最大工作信号为最大工作电压；当所述最小电信号为最小工作电流时，所述最大工作信号为最大工作电流；
所述功率放大器在线性放大区间分为3个区间，分别是区间1、区间2 和区间3；
所述区间1对应的工作信号范围为[E，E+(F-E)/2-delta)；
所述区间2对应的工作信号范围为[E+(F-E)/2-delta，E+(F-E)/2+delta]；
所述区间3对应的工作信号范围为(E+(F-E)/2+delta，F]；
其中，所述delta为小于(F-E)/2的正实数。
若第二通信节点直接向所述第一通信节点，上报的PA工作在静态工作点所对应的区间，则所述第一通信节点可以直接根据各个区间与发送方式之间的对应关系，确定出第二通信节点发送信息的发送方式。
在一些实施例中，当所述第二通信节点的所述功率放大器的静态工作点所处的区间为所述区间1或所述区间3时，则确定所述发送方式为离散傅里叶变换扩频的正交频分复用；
当所述第二通信节点的所述功率放大器的静态工作点所处的区间为所述区间2时，则确定所述发送方式为循环前缀正交频分复用。
在还有一些实施例中，当所述第一差值大于第一门槛值时或所述第二差值大于第二门槛值时，则所述发送方式为循环前缀正交频分复用，否则所述发送方式为离散傅里叶变换扩频的正交频分复用。
在一些实施例中，所述信令至少包括以下之一：
指示上行数据的调制编码方式索引信令、指示上行数据的调制方式信令、指示上行空间复用的秩信令、指示冗余版本的取值信令、配置上行参考信号所使用的序列类型的信令。
在本实施例中所述第一通信节点和第二通信节点之间，第一通信节点可以通过专用信令向第二通信节点至少确定的发送方式，也可以复用其他信令隐含指示所述发送方式。例如，在本实施例中所述信令为上述指示其他信息的信令。所述第一通信节点和第二通信节点都预先定义了其他信息与发送方式之间的对应关系，故第二通信节点在接收到所述信令之后，解 码所述信令，通过解码得到内容及所述对应关系，就知道当前第一通信节点确定的发送方式。当然若这样的话，第一通信节点在发送所述信令之前，需要根据确定的发送方式，和所述对应关系，选择能够指示当前选择的发送方式的信令指示给第二通信节点。
在一些实施例中，所述S200可包括：
当所述上行数据的调制方式为16正交幅度调制QAM或64QAM或256QAM或比256QAM更高阶的调制方式时、或者当上行数据的调制编码方式索引大于或等于C时，则双方预定义所述方式为循环前缀正交频分复用，否则双方预定义所述发送方式为离散傅里叶变换扩频的正交频分复用，其中，所述C为大于或等于2的正整数。
在另一些实施例中，所述步骤S200可包括：
16QAM或比256QAM更高阶的调制方式时、或者当上行数据的调制编码方式索引大于或等于C时，则双方预定义所述方式为循环前缀正交频分复用，当所述上行数据的调制方式不是16正交幅度调制QAM或64QAM或256QAM或比256QAM更高阶的调制方式时、或者当上行数据的调制编码方式索引小于所述C时，则双方预定义所述发送方式为循环前缀正交频分复用或所述离散傅里叶变换扩频的正交频分复用，其中，所述C为大于或等于2的正整数。即当上行数据的调制方式不是16正交幅度调制QAM或64QAM或256QAM或比256QAM更高阶的调制方式时、或者当上行数据的调制编码方式索引小于所述C时，可以随机选择一种循环前缀正交频分复用及所述离散傅里叶变换扩频的正交频分复用中的一种。
高阶的调制方式对一个信息编码调制之后，产生的数据量会更大，故在本实施例中为了平衡传输资源与数据量的关系，优先在当所述上行数据的调制方式为16正交幅度调制QAM或64QAM或256QAM或比256QAM更高阶的调制方式时、或者当上行数据的调制编码方式索引大于或等于C 时，采用频谱资源利用率更高的循环前缀正交频分复用作为所述发送方式。在本实施例中所述上行数据的调制编码方式索引与QAM的调制阶数之间的对应关系可参见如下表1。表1物下行共享信道(Physical Uplink Share Channel，PUSCH)的编码调制方式、传输块尺寸索引和冗余版本表格
Figure PCTCN2017115090-appb-000001
Figure PCTCN2017115090-appb-000002
这里的编码调制方式的调制阶数一定的，故编码调制方式的编码调制阶数与编码调制方式索引的对应关系，即为编码调制方式与编码调制方式索引的对应关系。
在一些实施例中，所述步骤S200可包括：
当上行空间复用的秩为1且所述上行数据的调制方式为正交相移键控QPSK或16正交幅度调制QAM时，或者当上行空间复用的秩为1且上行数据的调制编码方式索引小于或等于M1时，则双方预定义所述发送方式为离散傅里叶变换扩频的正交频分复用，否则双方预定义所述发送方式为循环前缀正交频分复用，其中，所述M1为2至30的整数。
通常若上行空间复用的秩为1，表明第二通信设备处于小区的边缘，优先采用正交性能更好的离散傅里叶变换扩频的正交频分复用，作为所述发送方式，以确保UE传输信号的正交性。
在另外一些实施例中，所述步骤S200可包括：
当上行空间复用的传输块数量为1且该传输块的调制方式为正交相移键控QPSK或16正交幅度调制QAM时，或者当上行空间复用的传输块数量为1且上行数据的调制编码方式索引小于或等于M2时，则双方预定义所 述发送方式为离散傅里叶变换扩频的正交频分复用，否则双方预定义所述发送方式为循环前缀正交频分复用，其中，所述M2为2至30的整数。
在另一些实施例中，所述步骤S200可包括：
当所述第一通信节点为第二通信节点配置的参考信号序列类型为Zadoffu Chu序列或恒模零自相关CAZAC序列时，则双方预定义所述发送方式为离散傅里叶变换扩频的正交频分复用；
当所述第一通信节点为第二通信节点配置的参考信号序列类型为伪随机PN序列时，则双方预定义所述发送方式为循环前缀正交频分复用。
这里的若第二通信节点为UE，第一通信节点为基站，则所述参考序列类型为上行参考信号序列类型。
一般情况下，若UE的上行参考信号序列类型为Zadoffu Chu序列或恒模零自相关CAZAC序列时，表明该UE对正交性要求比较高，故优先采用正交性更好的离散傅里叶变换扩频的正交频分复用，满足正交性需求。在另一些实施例中，所述步骤S200可包括：
当所述第一通信节点为第二通信节点配置的参考信号序列类型为Zadoffu Chu序列或恒模零自相关CAZAC序列时，则双方预定义所述发送方式为循环前缀正交频分复用；
当所述第一通信节点为第二通信节点配置的参考信号序列类型为伪随机PN序列时，则双方预定义所述发送方式为离散傅里叶变换扩频的正交频分复用。
通常UE位于小区边缘时，则所述参考信号序列类型为PN序列时，通常要求交高的传输性能，在本实施例中为了满足传输性能，则优先采用离散傅里叶变换扩频的正交频分复用，而采用Zadoffu Chu序列或恒模零自相关CAZAC序列时，可以采用循环前缀正交频分复用。
在另一些实施例中，所述步骤S200还可包括：所述第一通信节点和所 述第二通信节点双方预定义第二通信节点，在不同的时域资源使用不同的发送方式发送所述信息，其中，所述时域资源至少包括以下之一：时域符号、时隙、子帧、子帧集合。
此外，所述步骤S200可包括：所述第一通信节点和所述第二通信节点双方预定义第二通信节点在不同的频域资源使用不同的发送方式发送所述信息，其中，所述频域资源至少包括以下之一：频域资源块RB、RB集合、子载波、分量载波、频域带宽、频域子带。
在上述实施例中不仅会确定出发送方式，还会确定出使用对应发送方式的时频资源。所述时域资源可以包括时域符号、时隙、子帧或子帧集合。这里的频域资源可包括频域资源块(Resource Block,RB)、包括一个或多个频域资源块的RB集合、子载波、分量载波等信息。
所述方法还包括：所述第一通信节点向相邻小区发送指示所述发送方式的发送方式信息。
在本实施例中所述第一通信节点覆盖成一个小区A，则所述相邻小区为小区A的相邻小区。在本实施例中所述第一通信节点，会将指示其选中的发送方式的发送方式信息，发送给相邻小区。这里的发送给相邻小区，至少发送给相邻小区的第一通信节点，在具体实现时，还可以是第二通信节点，以方便相邻小区知道对应的第二通信节点发送信息，例如，上行信息，所采用的发送方式。
可选地，所述发送方式信息至少包括以下之一：时域资源上所使用的发送方式、频域资源上所使用的发送方式、波束域资源上所使用的发送方式。
如图4所示，本实施例提供一种发送方式确定方法，包括：
步骤S300：第二通信节点接收第一通信节点发送的信令，所述信令用于指示第二通信节点发送信息所使用的发送方式。
如图5所示，本实施例还提供另一种发送方式确定方法，包括：
步骤S400：第二通信节点和第一通信节点双方预定义第二通信节点发送信息所使用的发送方式，其中，所述信息包括业务数据和/或控制信息。这两种发送方式都应用于第二通信节点中，这里的第二通信节点可为各种类型的用户终端等。这里的而用户终端可包括人载用户终端，车载用户终端等终端。当然，这里的第二通信节点不局限于用户终端，还可以是物理网中的机器到机器(Machine 2 Machine，M2M)设备。
上述两种方式中，一种方式第二通信节点接收第一通信节点发送的信令，通过信令解析获得第一通信节点确定的发送方式。在后续通信过程中，若所述第二通信节点向所述第一通信节点发送信息时，则采用确定的发送方式来发送。在另一种方式中，第二通信节点和第一通信节点，预先定义发送方式，这样的话，第二通信节点也可以简便确定向第一通信节点发送信息的发送方式。在本实施例中所述发送方式至少包括以下之一：离散傅里叶变换扩频的正交频分复用、循环前缀正交频分复用。这样的话，第二通信节点可以采用离散傅里叶变换扩频的正交频分复用或循环前缀正交频分复用其中的一种向所述第一通信节点发送信息。
在一实施例中，在所述第一通信节点确定所述发送方式之前，所述方法还包括：
所述第二通信节点向所述第一通信节点上报所述第二通信节点建议的发送方式或所述第二通信节点的功率放大器PA的相关信息，所述相关信息至少包括以下之一：功率放大器的饱和区起始电压与静态工作点的电压之间的第一差值、功率放大器的饱和区起始电流与静态工作点的电流之间的第二差值、功率放大器的静态工作点所处的区间，
所述建议的发送方式或所述PA的相关信息，用于所述第一通信节点确定所述发送方式。
在本实施例中所述第二通信节点可以根据PA的相关信息或上行编码调制方式等各种依据参数，自行提出一种简易的发送方式，告知给第一通信节点，由第一通信节点根据第二通信节点的建议，进入确定是否采用建议的发送方式进行通信。
在另一些实施例中，所述第二通信节点将自身的PA的相关信息发送给第一通信节点，这样的话，第一通信节点可以根据第二通信节点的PA的相关信息，选择出适合当前第二通信节点的发送功率特点的发送方式供第二通信节点的信息发送，从而避免第二通信节点的发送功率不能满足某一种发送方式所需功耗产生的信号质量差等问题。
可选地，所述功率放大器在线性放大区间的最小工作信号为E，最大工作信号为F；当所述最小工作信号为最小工作电压时，所述最大工作信号为最大工作电压；当所述最小电信号为最小工作电流时，所述最大工作信号为最大工作电流；
所述功率放大器在线性放大区间分为3个区间，分别是区间1、区间2和区间3；
所述区间1对应的工作信号范围为[E，E+(F-E)/2-delta)；
所述区间2对应的工作信号范围为[E+(F-E)/2-delta，E+(F-E)/2+delta]；
所述区间3对应的工作信号范围为(E+(F-E)/2+delta，F]；
其中，所述delta为小于(F-E)/2的正实数。
在本实施例中，将功率放大器PA的线性发当区分为了3个区，然后PA的静态工作电所处的区间来决定采用哪一种发送方式。具体如，当所述第二通信节点的所述功率放大器的静态工作点所处的区间为所述区间1或所述区间3时，则所述发送方式为离散傅里叶变换扩频的正交频分复用；当所述第二通信节点的所述功率放大器的静态工作点所处的区间为所述区间2时，则所述发送方式为循环前缀正交频分复用。
第一通信节点向第二通信节点指示发送方式的信令有多种，在本实施例中采用如下信令进行复合指示或隐含指示。所述信令至少包括以下之一：指示上行数据的调制编码方式索引信令、指示上行数据的调制方式信令、指示上行空间复用的秩信令、指示冗余版本的取值信令、配置上行参考信号所使用的序列类型的信令。
上述信令携带的信息内容或信令本身与发送方式具有映射关系，当第一通信节点向第二通信节点发送对应的信令或信令内容时，第二通信节点就可以根据这种映射关系确定出当前第一通信节点确定出的发送方式是离散傅里叶变换扩频的正交频分复用，还是循环前缀正交频分复用。
当然在一些实施例中还可以通过通信双方构建专用信令进行指示，但是在本实施例中利用与已有的信令的复用，实现隐含指示，具有可以减少信令开销，减少第一通信节点和第二通信节点之间的信令交互次数优点。
在有一些实施例中，当所述上行数据的调制方式为16正交幅度调制QAM或64QAM或256QAM或比256QAM更高阶的调制方式时、或者当上行数据的调制编码方式索引大于或等于C时，则双方预定义所述方式为循环前缀正交频分复用，否则双方预定义所述发送方式为离散傅里叶变换扩频的正交频分复用，其中，所述C为大于或等于2的正整数。
在还有一些实施例中，所述上行数据的调制方式为16正交幅度调制QAM或64QAM或256QAM或比256QAM更高阶的调制方式时、或者当上行数据的调制编码方式索引大于或等于C时，则双方预定义所述方式为循环前缀正交频分复用，当所述上行数据的调制方式不是16正交幅度调制QAM或64QAM或256QAM或比256QAM更高阶的调制方式时、或者当上行数据的调制编码方式索引小于所述C时，则双方预定义所述发送方式为循环前缀正交频分复用或所述离散傅里叶变换扩频的正交频分复用。
