具体实施方式
为使本申请的目的、技术方案和优点更加清楚明白,下文中将结合附图对本申请的实施例进行详细说明。需要说明的是,在不冲突的情况下,本申请中 的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且,虽然在流程图中示出了逻辑顺序,但是在某些情况下,可以以不同于此处的顺序执行所示出或描述的步骤。
本申请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,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LIE-A(Advanced long term evolution,先进的长期演进)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、以及第五代移动通信技术(5th-Generation,5G)系统等,本申请实施例并不限定。在本申请中以5G系统为例进行说明。
本申请实施例可以用于不同的制式的无线网络。无线接入网络在不同的系统中可包括不同的通信节点。图1为本申请实施例提供的一种无线网络系统的结构示意图。如图1所示,该无线网络系统100包括基站101、用户设备110、用户设备120和用户设备130。基站101分别与用户设备110、用户设备120和用户设备130之间进行无线通信。
首先,需要说明的是,本申请实施例中,基站可以是能和用户终端进行通信的设备。基站可以是任意一种具有无线收发功能的设备。包括但不限于:基站NodeB、演进型基站eNodeB、5G通信系统中的基站、未来通信系统中的基站、WiFi系统中的接入节点、无线中继节点、无线回传节点等。基站还可以是云无线接入网络(cloud radioaccess network,CRAN)场景下的无线控制器;基站还可以是小站,传输节点(transmission reference point,TRP)等,本申请实施 例并不限定。
本申请实施例中,用户终端是一种具有无线收发功能的设备可以部署在陆地上,包括室内或室外、手持、穿戴或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。所述用户终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality,VR)终端、增强现实(Augmented Reality,AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。用户终端有时也可以称为终端、接入终端、用户设备(User Equipment,UE)单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等。本申请实施例并不限定。
在Release-16版本的NB-IoT技术中,最大调制方式支持QPSK调制,QPSK调制方式的峰值速率为126.8千比特每秒。在Release-17版本中,NB-IoT将最大调制方式提高到16QAM调制,以支持更高的数据传输速率。然而,最大调制方式从QPSK调制提升至16QAM调制后,现有的调制编码策略(Modulation and Coding Scheme,MCS)将不能满足数据的调制编码需求,需要新的调制编码策略MCS。因此,为了支持NB-IoT的16QAM调制,新的调制编码策略MCS表格需要定义。
在一个实施例中,本申请提供一种配置方法,图2为本申请实施例提供的一种配置方法的流程示意图。该方法可以适用于基于调制方式确定数据MCS的情况。该方法可以由本申请提供的配置装置执行,该配置装置可以由软件和/或 硬件实现,所述方法应用于第一通信节点中。
如图2所示,本申请实施例提供的配置方法主要包括步骤S21和S22。
S21、基于高层配置参数确定调制编码策略MCS集合,其中,所述高层配置参数指示了数据传输是否支持正交幅度调制16QAM方式,所述MCS集合包括以下一个或多个:第一MCS集合、第二MCS集合。
S22、基于所述MCS集合配置数据的MCS。
在本实施例中,上述第一通信节点可以是上述任意一种基站。在本实施例中,所述MCS集合可以是MCS、调制方式以及传输块尺寸(Transport Block Size,TBS)之间的对应关系。具体地,所述MCS集合包含多个MCS,每个MCS对应一个调制方式和一个TBS。所述第一MCS集合中,最高的调制方式为16QAM。所述第二MCS集合中,最高的调制方式为QPSK。
需要说明的是,第一MCS集合和第二MCS集合仅仅是为了区分不同的调制方式对应的集合,并不限定是实际的两个集合,也可以在一个集合中的两个子集或者一个集合中表示的两种不同对应关系。第一MCS集合和第二MCS集合只是为了便于相互区分的表述,并不用于限制本申请的保护范围。
在本实施例中,所述MCS集合可以用表格的形式进行表示,也可以采用其他方式进行表示,本实施例中仅进行说明,而非限定。
进一步的,所述第一通信节点基于高层配置参数确定MCS表格,然后基于所述MCS表格配置数据的MCS。
其中,所述高层配置参数由第一通信节点配置,具体配置方式本实施例中不进行限定。
本实施例中,所述MCS集合包含T个MCS,每个MCS对应一个调制方式和一个TBS,因此,确定一个MCS,即可确定数据的传输块尺寸TBS和调制方 式。当通信节点为数据配置MCS时,会从所述T个MCS中选择一个,对数据进行编码调制。
本实施例中,所述第一MCS集合最高的调制方式为16QAM,所述第二MCS集合最高的调制方式为QPSK。
所述第二MCS集合为Release-16版本(现有最新版本)标准协议中已定义的MCS集合。
需要说明的是,在NB-IoT中,所述第二MCS集合满足对应关系:MCS索引0至13分别对应TBS索引0至13,调制方式为QPSK,所述索引即为序号。其中,所述传输块尺寸TBS为一个数据传输块的比特数量,在TBS表格中,不同的TBS索引对应着不同的TBS,所述TBS表格在现有标准协议中定义。
在一个示例性的实施方式中,所述基于高层配置参数确定MCS集合,包括:
在数据传输支持16QAM调制方式的情况下,所述MCS集合是第一MCS集合或第二MCS集合;
在数据传输不支持16QAM调制方式的情况下,所述MCS集合是第二MCS集合。
本实施例中,所述数据传输支持16QAM调制方式,表示数据传输时可以使用16QAM;所述数据传输不支持16QAM调制方式,表示数据传输时只能使用比16QAM低阶的调制方式,例如QPSK。
进一步地,所述数据传输支持16QAM调制方式的情况下,基于第一MCS集合或第二MCS集合来配置数据的MCS,表示数据传输时可以使用所述第一MCS集合或第二MCS集合,为数据配置MCS。
进一步地,所述数据传输不支持16QAM调制方式的情况下,基于第二MCS集合来配置数据的MCS,表示数据传输时仅可以使用所述第二MCS集合为数 据配置MCS。
本实施例中,因为16QAM的调制阶数较高,所以解调时需求较好的信道条件,差的信道条件不适合16QAM解调。因此,当高层配置参数P指示数据传输支持16QAM时,数据传输可以使用第一MCS集合,也可以使用第二MCS集合为数据配置MCS。当高层配置参数P指示数据传输不支持16QAM时,仅仅可以使用第二MCS集合为数据配置MCS。
在一个示例性的实施方式中,所述在数据传输支持16QAM调制方式的情况下,所述MCS集合是第一MCS集合或第二MCS集合,包括:
在数据传输支持16QAM调制方式,且物理共享信道的重复次数小于或等于预设门限值的情况下,所述MCS集合是第一MCS集合;
在数据传输支持16QAM调制方式,且物理共享信道的重复次数大于预设门限值的情况下,所述MCS集合是第二MCS集合。
在本实施例中,在数据传输支持16QAM调制方式的情况下,物理共享信道的最大重复次数大于或者等于1024。
在一个示例性的实施方式中,利用下行控制信息中的重复次数域指示重复次数和MCS集合。
进一步的,在数据传输支持16QAM调制方式的情况下,利用下行控制信息中的重复次数域指示重复次数和MCS集合。
所述重复次数域包含4比特信息,具有16个取值,每个取值对应一个重复次数和一个MCS表格,
进一步的,所述重复次数域包含H个取值,其中,J个取值对应第一MCS集合,其余H-J个取值对应第二MCS集合,J是大于或等于1的整数,H是大于或等于1的整数。

在一个示例性的实施方式中,对于上行传输,在所述第一MCS集合中, MCS索引MCS 0至MCS 10分别对应TBS索引TBS 0至TBS 10,且MCS索引MCS 0至MCS 10对应的调制方式是QPSK调制方式;MCS索引MCS 11至MCS 15分别对应TBS索引TBS 9至TBS 13,且MCS索引MCS 11至MCS 15对应的调制方式是16QAM调制方式。
在一个应用性实例中,本申请提供一种调制编码策略的配置方法,包括:基于高层配置参数确定调制编码策略(Modulation and Coding Scheme,MCS)表格;基于所述MCS表格配置数据的MCS;其中,所述高层配置参数指示了数据传输是否支持正交幅度调制16QAM方式,所述MCS表格包括以下一个或多个:第一MCS表格、第二MCS表格。
本实施例中,MCS表格包含T个MCS,每个MCS对应一个调制方式和一个TBS,因此,确定一个MCS,即可确定数据的传输块尺寸TBS和调制方式。当第一通信节点为数据配置MCS时,会从所述T个MCS中选择一个,对数据进行编码调制。
本实施例中,所述第一MCS表格最高的调制方式为16QAM,所述第二MCS表格最高的调制方式为QPSK。
所述第二MCS表格为Release-16版本(现有最新版本)标准协议中已定义的MCS表格。在NB-IoT中,所述第二MCS表格不存在具象化的表格,但满足对应关系:MCS索引0至13分别对应TBS索引0至13,调制方式为QPSK,所述索引即为序号。其中,所述传输块尺寸TBS为一个数据传输块的比特数量,在TBS表格中,不同的TBS索引对应着不同的TBS,所述TBS表格在现有标准协议中定义。
本实施例中,第一通信节点向第二通信节点发送所述高层配置参数P,所述 高层配置参数P直接或间接指示数据传输是否支持16QAM调制。具体地,高层配置参数P可以是直接指示数据传输是否支持16QAM调制的参数信令;高层配置参数P也可以是间接指示数据传输是否支持16QAM调制的参数信令,例如,高层配置参数P指示数据传输是否支持所述第一MCS表格,如果支持所述第一MCS表格,则间接表明数据传输支持16QAM调制,否则,间接表明数据传输不支持16QAM调制。
本实施例中,所述支持16QAM调制方式,表示数据传输时最高可以使用16QAM调制方式,同时也可以使用其他调制方式;所述不支持16QAM调制方式,表示数据传输时只能使用比16QAM低阶的调制方式,例如QPSK。
本实施例中,在数据传输支持16QAM调制方式的情况下,所述MCS表格是第一MCS表格或第二MCS表格;在数据传输不支持16QAM调制方式的情况下,所述MCS表格是第二MCS表格。
本实施例中,因为16QAM的调制阶数较高,所以解调时需求较好的信道条件,差的信道条件不适合16QAM解调。因此,在数据传输支持16QAM调制方式的情况下,数据传输可以使用第一MCS表格来支持16QAM调制,也可以使用第二MCS表格不支持16QAM调制。那么,所述第一MCS表格和第二MCS表格的动态切换可以考虑如下两个方案:
MCS表格切换方案一:在数据传输支持16QAM调制方式的情况下,如果物理共享信道的重复次数小于或等于预设门限值,则基于第一MCS表格来配置数据的MCS;如果物理共享信道的重复次数大于预设门限值,则基于第二MCS表格来配置数据的MCS。
具体地,在数据传输支持16QAM调制方式的情况下,如果物理共享信道的重复次数小于或等于门限值,即重复次数较小,说明信道条件较好,所以基于 第一MCS表格来配置数据的MCS;如果物理共享信道的重复次数大于门限值,说明信道条件差,则基于第二MCS表格来配置数据的MCS。所述门限值为一个固定的重复次数或由基站配置。
方案二:在数据传输支持16QAM调制方式的情况下,利用下行控制信息中的重复次数域指示重复次数和MCS表格。所述重复次数域包含H个取值,其中J个取值对应第一MCS表格,其余H-J个取值对应第二MCS表格,J大于或等于1。
具体地,在数据传输支持16QAM调制方式的情况下,物理共享信道的重复次数和MCS表格的选取,这两项内容联合由重复次数域指示。所述重复次数域具有H个取值,每个取值对应一个重复次数和一个MCS表格,其中,J个取值对应第一MCS表格,其余H-J个取值对应第二MCS表格,具体的对应关系由一个重复次数域的指示表格来确定。
进一步地,因为高层配置参数P不会在大重复次数下指示支持16QAM调制,所以,可以利用所述重复次数域的J个取值来对应第一MCS表格和小重复次数,用来支持16QAM调制,剩余的H-J个取值来对应第二MCS表格和H-J种重复次数。例如,当H=16,J=2时,所述重复次数域的最大两个取值对应第一MCS表格,且所述最大两个取值分别对应重复次数1和2,所述重复次数域的较小的14个取值对应第二MCS表格,且所述较小的14个取值对应14个不同的重复次数。
本实施例中,当基站配置了混合自动重传(Hybrid Automatic Repeat reQuest,HARQ),如果数据传输块的HARQ首传采用低重复次数,且数据传输块的尺寸大于TBS 13,且HARQ首传没有正确译码,那么,基站可采用以下两种操作方法:
方法一:放弃该数据传输块,不再继续该传输块的HARQ重传;重新选择重复次数和MCS,配置新的数据传输块。
方法二:HARQ重传不增加重复次数;或者HARQ重传增加的重复次数不超过所述第一MCS表格支持的最大重复次数,对于MCS表格切换方案一,所述第一MCS表格支持的最大重复次数即为所述门限值,对于MCS表格切换方案二,所述第一MCS表格支持的最大重复次数为所述重复次数域的指示表格中对应所述第一MCS表格的最大重复次数。
本实施例中,所述物理共享信道为物理下行共享信道(Physical Downlink Share Channel,PDSCH)或物理上行共享信道(Physical Uplink Share Channel,PUSCH)。
本实施例中,在所述第一MCS表格和所述第二MCS表格之间,满足关系:针对所述第二MCS表格,移除N个传输块尺寸TBS索引,加入N+2个TBS索引,即得到所述第一MCS表格的TBS索引;其中,移除的TBS索引小于或等于TBS 13,加入的TBS索引大于TBS 13,N是大于或等于0的整数;
具体地,在NB-IoT中,所述第二MCS表格包含14个MCS,MCS索引0至13分别对应TBS索引0至13。基于这个MCS表格,移除其中N个TBS,加入N+2个TBS,加入的TBS索引大于TBS 13,即可得到所述第一MCS表格包含的TBS。所述第一MCS表格包含16个TBS,对应MCS索引0至15。
本实施例中,所述针对所述第二MCS表格,移除N个TBS索引,可以采用以下五种方案之一:
移除TBS方案一:移除N个TBS奇数索引。例如:移除6个TBS,包括TBS 1、3、5、7、9、11;相应地加入8个TBS,包括TBS 14至21。
移除TBS方案二:移除N个TBS偶数索引。例如:移除6个TBS,包括 TBS 2、4、6、8、10、12;相应地加入8个TBS,包括TBS 14至21。
移除TBS方案三:移除N个连续的TBS索引。例如:移除7个连续的TBS,包括TBS 1至7;相应地加入9个TBS,包括TBS 14至22。
移除TBS方案四:移除N1个连续的TBS索引和N2个TBS奇数索引,其中N1+N2=N。
移除TBS方案五:移除N1个连续的TBS索引和N2个TBS偶数索引,其中N1+N2=N。
本实施例中,在所述第一MCS表格和所述第二MCS表格之间,也可以满足关系:针对所述第二MCS表格,保留M个TBS索引,加入T个TBS索引,即得到所述第一MCS表格的TBS索引,其中,保留的TBS索引小于或等于TBS13,加入的TBS索引大于TBS 13,T+M=16,T和M均是大于或等于0的整数。
本实施例中,所述针对所述第二MCS表格,保留M个TBS索引,可以采用以下五种方案之一:
移除TBS方案一:保留M个TBS奇数索引。
移除TBS方案二:保留M个TBS偶数索引。
移除TBS方案三:保留M个连续的TBS索引。
移除TBS方案四:保留M1个连续的TBS索引和M2个TBS奇数索引,其中M1+M2=M。
移除TBS方案五:移除M1个连续的TBS索引和M2个TBS偶数索引,其中M1+M2=M。
本实施例中,在所述第一MCS表格中,对应16QAM调制方式的MCS数量为K个,对应QPSK调制方式的MCS数量为L个,K大于或等于L。也就是说,16QAM调制的MCS数量大于或等于QPSK的数量。假设所述第一MCS表格包 含16个MCS,包含两种调制方式QPSK和16QAM,则16QAM调制方式的MCS数量至少为8个。
进一步地,在所述第一MCS表格中,也可以仅包含采用16QAM调制的MCS。假设所述第一MCS表格包含16个MCS,则对应16QAM调制方式的MCS数量K等于16,即16个MCS都为16QAM调制。
本实施例中,在所述第一MCS表格中,最大的TBS索引为TBS 21或TBS 22,对应的调制方式为16QAM。
本实施例中,对于NB-IoT带内(In band)部署方式,16QAM调制下支持的最大TBS不超过TBS 16。那么,对于In band模式,可用的MCS可以采用如下两个方案之一:
In band模式方案一:In band模式与独立部署(stand alone)方式共用同一个16QAM MCS表格(即所述第一MCS表格),但在所述16QAM MCS表格中,In band模式可配置的TBS小于或等于TBS 16。也就是说,对于In band模式,基于所述第一MCS表格,TBS索引小于或等于16的MCS可用于配置数据,TBS索引大于16的MCS不被使用。
In band模式方案二:对于In band模式,采取专用于In band模式的16QAM MCS表格,即In band模式下的第一MCS表格,所述In band模式的第一MCS表格包含16个MCS,所述16个MCS对应TBS 0至15;或者,所述16个MCS对应TBS 0至16中的15个TBS,且所述15个TBS索引中包含TBS 16。
对于上行传输,在所述第一MCS表格中,MCS 0至10分别对应TBS 0至10,且MCS 0至10的调制方式为QPSK;MCS 11至15分别对应TBS 9至13,且MCS 11至15的调制方式为16QAM。这是因为上行16QAM调制支持的最大TBS为TBS13,所以,在上行传输中,所述第一MCS表格最大的MCS对应TBS 13。
在一个应用性实施方式中,本申请提供一种MCS表格,用于支持调制阶数最高至16QAM,包括:
本实施例中,第二MCS表格包含14个MCS,分别为MCS 0至13,依次对应TBS 0至13,调制方式都是QPSK。
本实施例中,基于所述第二MCS表格,移除其中N个TBS奇数索引,加入N+2个大于13的TBS索引,即为第一MCS表格包含的TBS。
进一步地,在所述第一MCS表格中,MCS索引与TBS索引的对应关系采用以下两种方式之一:
MCS-TBS对应方式一:针对TBS索引0至13,移除所述N个TBS奇数索引,分别为索引I 1、I 2……I N,剩余TBS索引J 1、J 2……J 14-N。在所述第一MCS表格中,MCS索引J 1、J 2……J 14-N依次对应TBS索引J 1、J 2……J 14-N,MCS索引I 1、I 2……I N对应N个大于13的TBS索引,MCS索引14、15对应2个大于13的TBS索引。
MCS-TBS对应方式二:在所述第一MCS表格中,TBS从小到大依次对应MCS 0至15。
本实施例中,在所述第一MCS表格中,对应16QAM调制方式的MCS数量为K个,对应QPSK调制方式的MCS数量为L个,K大于或等于L。
本实施例中,在所述第一MCS表格中,最大的TBS索引为TBS 21或TBS 22,对应的调制方式为16QAM。
本实施例中,对于In band模式,基于所述第一MCS表格,TBS索引小于或等于16的MCS可用于配置数据,TBS索引大于16的MCS不被使用。
本实施例中,QPSK的调制阶数为2,16QAM的调制阶数为4。
