在介绍本申请技术方案之前,下面首先介绍SRS、基于非码本的上行传输方案、基于码本的上行传输方案以及在上行传输方案中SRS资源的指示方式:
一、SRS
SRS可用于CSI获取、下行信道信息获取以及上行波束管理。NR系统以SRS资源集的方式进行SRS的管理和配置。其中,根据不同的用途,网络设备可以为终端设备配置多个SRS资源集,每个SRS资源集包括一个或多个SRS资源,每个SRS资源包含1、2或4个端口。每个SRS资源集的配置信息中包含一个用途指示,可以被配置为“beamManagement”“codebook”“nonCodebook”或“antennaswitching”,分别用于上行波束管理、基于码本的CSI获取,基于非码本的CSI获取以及基于SRS天线切换的下行信道信息获取。
二、基于非码本的上行传输方案
基于非码本的上行传输方案与基于码本的上行传输方案的区别在于:基于非码本的上行传输方案的预编码不再限定在基于固定码本的有限候选集中,终端设备基于信道互易性确定上行预编码矩阵。若信道互易性足够好,终端设备可以获得较优的上行预编码,相对于基于码本的传输方案,可以节省预编码指示的开销,同时获得更好的性能。图2为基于非码本的上行传输方案的流程图,如图2所示,基于非码本的上行传输方案包括如下步骤:
S210:终端设备测量下行参考信号,获得候选的上行预编码矩阵。
S220:终端设备利用候选的上行预编码矩阵对用于非码本上行传输方案的至少一个SRS进行预编码。
S230:终端设备将该至少一个SRS发送给网络设备。
S240:网络设备对至少一个SRS的信道进行测量,得到信道测量结果,并根据信道测量结果在SRS集合中选择SRS资源、传输层数、解调参考信号(Demodulation Reference Sgnal,DMRS)端口指示信息,PUSCH资源分配和相应的调制与编码策略(Modulation and Coding Scheme,MCS)等级。
S250:网络设备向终端设备发送下行控制信令(Downlink control information,DCI)。
该DCI包括SRI、DMRS端口指示信息、PUSCH资源分配和相应的MCS等级,其中SRI用于指示网络设备所选择的SRS资源。
S260:终端设备根据该MCS等级对PUSCH的数据进行调制编码,并利用SRI确定该数据发送时使用的预编码矩阵和传输层数。
S270:终端设备根据预编码矩阵、传输层数对PUSCH进行预编码传输。
其中,PUSCH的DMRS与PUSCH的数据采用相同的预编码。
S280:网络设备根据DMRS估计上行信道,并进行PUSCH的数据的解调、解码。
对于基于非码本的上行传输方案,网络设备可以为终端设备配置1个用于上行CSI获取的SRS资源集,该SRS资源集包含1-4个SRS资源,每个SRS资源包含1个SRS端口。SRI可以指示网络设备选择的一个或多个SRS资源,用于PUSCH预编码的确定。SRI指示的SRS资源数即为PUSCH的传输层数,即PUSCH的传输层数与SRI指示的SRS资源一一对应。
对于非码本上行传输方案,终端设备需要基于信道互易性,根据下行参考信号获得上行预编码信息。一个终端设备可以被配置多个下行参考信号,有的下行参考信号可用于波束管理,有的下行参考信号可用于下行CSI的测量,有的下行参考信号可用于下行信道的解调。为了使终端设备获得更好的用于非码本上行传输方案的候选预编码,在NR系统中,允许网络设备为用于非码本上行传输方案的SRS资源集配置一个用于信道测量的关联NZP CSI-RS资源。终端设备根据该关联NZP CSI-RS资源可获得用于非码本上行传输方案的SRS资源集的SRS信号传输的预编码。
三、基于码本的上行传输方案
图3为基于码本的上行传输方案的流程图,如图3所示,NR系统R16中基于码本的上行传输方案包括如下步骤:
S310:终端设备根据网络设备向其配置的SRS资源向网络设备发送至少一个SRS。
S320:网络设备对至少一个SRS的信道进行测量,得到信道测量结果,并根据信道测量结果在SRS集合中选择SRS资源、TPMI,DMRS端口指示信息,PUSCH资源分配和相应的MCS等级。
S330:网络设备向终端设备发送DCI。
其中,该DCI中包括:SRI、TPMI、DMRS端口指示信息、PUSCH资源分配和相应的MCS等级,其中SRI用于指示网络设备所选择的SRS资源。
S340:终端设备根据MCS对PUSCH的数据进行调制编码,并利用SRI、TPMI确定该数据发送时使用的预编码矩阵,利用SRI确定传输层数,并使用TPMI从码本中选择PUSCH的预编码器。
S350:终端设备根据预编码矩阵、传输层数,并通过选择的预编码器对PUSCH进行预编码传输。
其中,PUSCH的DMRS与PUSCH的数据采用相同的预编码。
S360:网络设备根据DMRS估计上行信道,并进行PUSCH的数据的解调、解码。
在R16及以前,在NR系统中,允许网络设备为终端设备最多配置一个用于基于码本的CSI获取的SRS资源集,该SRS资源集内最多可配置两个SRS资源,这两个SRS资源包含相同的SRS天线端口数。由于在R17中引入了基于多TRP对PUSCH的增强,因此从R17开始,NR系统允许网络设备为终端设备最多配置两个用于基于码本CSI获取的SRS资源集,R17中并没有对这两个资源集中可以包含的资源数目是否相同进行限制。
网络设备通过DCI中的SRI向终端设备指示选择的SRS资源,以辅助终端设备根据网络设备选择的SRS资源确定PUSCH传输所用的天线和模拟波束赋形等。由于网络设备为不同的上行传输方案配置的SRS资源的数目可能不同,因此,基于上行传输方案来确定SRI占用的比特数,可以降低SRI的开销。因此SRI占用的比特数取决于上行传输方案所配置的SRS资源数。当网络设备为终端设备的一个上行传输方案只配置了一个SRS资源时,该上行传输方案下的PUSCH对应于该SRS资源,因此,DCI中可以不存在SRI指示域。
四、基于码本的上行传输方案中的SRI
下行控制信道承载网络设备发送给终端设备的DCI,其中DCI format 0_0,DCI format 0_1以及DCI format 0_2用于调度上行PUSCH。在DCI format 0_1和DCI format 0_2中,有一个SRI指示域,该SRI指示域携带SRI。在基于非码本的上行传输方案中,由于一个SRS资源对应一个传输层,因此,网络设备基于终端设备发送的SRS进行上行信道检测,选择其中的一个或多个SRS资源,并通过SRI指示给终端设备,该SRI指示域占用占用
Figure PCTCN2021081646-appb-000001
比特,其中,N SRS为配置了用于非码本传输的SRS资源集中的SRS资源个数,L max为可配置的最大层数。在码本传输中,由于每次只会选择一个SRS资源作为上行传输时的资源参考,因此该SRI指示域占用
Figure PCTCN2021081646-appb-000002
比特,其中N SRS为配置了用于非码本传输的SRS资源集中的SRS资源个数。
如上所述,目前存在基于一个SRS资源集的单TRP上行传输方案以及基于两个SRS资源集的多TRP上行重复传输方案。那么如何灵活的采用单TRP上行传输方案或者多TRP上行重复传输方案是本申请亟待解决的技术问题。
此外,当用于上行传输的SRS资源集中的SRS资源数量为1时,按照R15及R16的设计原则,此时DCI中将不会有SRI指示域存在,但是,如果在多TRP上行重复传输方案中,如果也按照R15以及R16的设计,即没有SRI指示域,那么多TRP上行重复传输存在可能会被误认为是单TRP上行传输。
为了解决该技术问题,本申请在DCI中引入一个新的指示域,来指示当前上行传输使用的SRS资源集,以表示或者隐含指示当前上行传输采用的是单TRP上行传输方案或者多TRP上行重复传输方案。
下面将对本申请技术方案进行详细阐述:
图4为本申请实施例提供的一种无线通信方法的交互流程图,该方法涉及的执行主体包括:网络设备和终端设备,其中,该终端设备配置有两个SRS资源集,如图4所示,该方法包括如下步骤:
S410:网络设备向终端设备发送DCI,该DCI包括第一指示信息,其中,第一指示信息指示两个SRS资源集中的一个SRS资源集,以表示通过一个SRS资源集中的SRS资源进行单TRP上行传输,或者,第一指示信息指示两个SRS资源集,以表示通过两个SRS资源集中的SRS资源进行多TRP上行重复传输。
S420:终端设备根据第一指示信息进行单TRP上行传输或者多TRP上行重复传输。
应理解的是,该DCI用调度上行传输,该上行传输是单TRP上行传输或者多TRP上行重复传输。
应理解的是,该上行传输也被称为PUSCH传输,基于此,单TRP上行传输也被称为单TRP PUSCH传输。多TRP上行重复传输也被称为PUSCH传输。
应理解的是,该单TRP上行传输可以是单TRP上行非重复传输或者单TRP上行重复传输。
可选的,单TRP上行传输是基于码本的单TRP上行传输或者基于非码本的单TRP上行传输。
可选的,多TRP上行重复传输是基于码本的多TRP上行重复传输或者基于非码本的多TRP上行重复传输。
可选的,多TRP上行重复传输占用不同的时频资源。
应理解的是,每个SRS资源集包括至少一个SRS资源,网络设备为上述两个SRS资源集配置相同的上行传输方式,例如:这两个SRS资源集都对应基于码本的上行传输或者基于非码本的上行传输。
可选的,第一指示信息占用的比特数,或者,第一指示信息所在的指示域占用的比特数与网络设备为终端设备配置的SRS资源集的数量有关,例如:网络设备为终端设备配置了两个SRS资源集,那么该第一指示信息占用的比特数为2。
可选的,当第一指示信息指示两个SRS资源集时,这两个SRS资源集具有先后顺序,例如:第一指示信息依次指示第一SRS资源集(例如SRS资源集0)、第二SRS资源集(例如SRS资源集1),或者,第一指示信息依次指示第二SRS资源集(例如SRS资源集1)、第二SRS资源集(例如SRS资源集0)。因此,第一指示信息存在四种取值,例如分别对应如表1所示的四种情况:
表1
第一指示信息 对应的含义
0 SRS资源集0和SRS资源集1
1 SRS资源集1和SRS资源集0
2 SRS资源集0
3 SRS资源集1
可选的,当第一指示信息指示两个SRS资源集时,这两个SRS资源集也可以不具有先后顺序,因此,第一指示信息存在三种取值,例如分别对应如表2所示的三种情况:
表2
第一指示信息 对应的含义
0 SRS资源集0和SRS资源集1
1 SRS资源集0
2 SRS资源集1
综上,在本申请中,在DCI中引入一个新的指示域,即第一指示信息所在的指示域,来指示当前上行传输使用的SRS资源集,以灵活的表示或者隐含指示当前上行传输采用的是单TRP上行传输方案或者多TRP上行重复传输方案。
可选的,若第一指示信息指示两个SRS资源集,则DCI中还包括SRI指示域,SRI指示域中的SRI用于指示选择的SRS资源,其中,SRS资源集与SRI指示域之间以下任一关系:
可实现方式一:若第一指示信息指示两个SRS资源集,则DCI中还包括两个SRI指示域,两个SRI指示域与两个SRS资源集一一对应。
示例性的,假设第一指示信息依次指示SRS资源集0和SRS资源集1,那么DCI中包括两个SRI指示域,依次是SRI指示域0和SRI指示域1,其中,SRS资源集0和SRI指示域0对应,SRS资源集1与SRI指示域1对应。即SRI指示域0中的SRI用于指示在SRI资源集0中选择的SRS资源,SRI指示域1中的SRI用于指示在SRI资源集1中选择的SRS资源。
需要说明的是,在可实现方式一中,本申请对SRS资源集中的SRS资源数量不做限制,即无论SRS资源集包括的SRS资源的数量是1个或者多个,SRS资源集都有对应的SRI指示域。
可实现方式二:若第一指示信息指示两个SRS资源集,且两个SRS资源集中的一个SRS资源集包括一个SRS资源,另一个SRS资源集包括多个SRS资源,则DCI还包括一个SRI指示域,一个SRI指示域与另一个SRS资源集对应。
示例性的,假设第一指示信息依次指示SRS资源集0和SRS资源集1,且SRS资源集0包括1个SRS资源,SRS资源集1包括2个SRS资源,那么DCI中包括1个SRI指示域,例如SRI指示域0,其中,SRS资源集1和SRI指示域0对应。即SRI指示域0中的SRI用于指示在SRI资源集1中选择的SRS资源。
可实现方式三:若第一指示信息指示两个SRS资源集,且两个SRS资源集均包括一个SRS资源,则DCI不包括SRI指示域。
示例性的,假设第一指示信息依次指示SRS资源集0和SRS资源集1,且SRS资源集0和SRS资源集1均包括1个SRS资源,那么DCI可以不包括SRI指示域。
可选的,若第一指示信息指示两个SRS资源集,且DCI包括两个SRI指示域,多TRP上行重复传输是基于码本的上行传输方式,则针对两个SRI指示域中的任一个SRI指示域,SRI指示域占用的比特数为max{1,log 2N},其中,N为SRI指示域对应的SRS资源集合包括的SRS资源的数量。或者,若第一指示信息指示两个SRS资源集,且DCI包括两个SRI指示域,多TRP上行重复传输是基于非码本的上行传输方式,针对两个SRI指示域中的任一个SRI指示域,SRI指示域占用的比特数为
Figure PCTCN2021081646-appb-000003
其中N SRS为SRI指示域对应的SRS资源集合包括的SRS资源的数量,L max为SRI指示域对应的SRS资源集合包括的SRS资源可配置的最大层数。
如上所述,当第一指示信息指示两个SRS资源集,且DCI包括两个SRI指示域时,而这两个SRS资源集可以具有先后顺序,也可以不具有先后顺序,下面将针对这两个情 况,示例性地说明两个SRS资源集与两个SRI指示域的对应关系。
示例1:假设第一指示信息依次指示SRS资源集0、SRS资源集1,且DCI包括两个SRI指示域,依次分别是SRI指示域0、SRI指示域1,那么SRS资源集0与SRI指示域0对应,SRS资源集1与SRI指示域1对应。
示例2:假设第一指示信息依次指示SRS资源集1、SRS资源集0,且DCI包括两个SRI指示域,依次分别是SRI指示域0、SRI指示域1,那么SRS资源集1与SRI指示域0对应,SRS资源集0与SRI指示域1对应。
示例3:假设第一指示信息指示SRS资源集0和SRS资源集1,但是这两个SRS资源集之间没有先后顺序,且DCI包括两个SRI指示域,那么终端设备可以采用SRS资源集与SRI指示域之间的默认关系,如该默认关系是SRS资源集0与SRI指示域0对应,SRS资源集1与SRI指示域1对应。或者,SRS资源集1与SRI指示域0对应,SRS资源集0与SRI指示域1对应。
示例4:假设第一指示信息指示SRS资源集0和SRS资源集1,但是这两个SRS资源集之间没有先后顺序,且DCI包括两个SRI指示域,那么这时网络设备还可以在该DCI中携带第二指示信息,以指示两个SRS资源集与两个SRI指示域之间的一一对应关系。如该一一对应关系是SRS资源集0与SRI指示域0对应,SRS资源集1与SRI指示域1对应。或者,SRS资源集1与SRI指示域0对应,SRS资源集0与SRI指示域1对应。
可选的,若第一指示信息指示两个SRS资源集,且多TRP上行重复传输是基于码本的上行传输方式,则DCI还包括两个TPMI指示域,两个TPMI指示域与两个SRS资源集一一对应。
如上所述,当第一指示信息指示两个SRS资源集,且DCI包括两个STPMI指示域时,而这两个SRS资源集可以具有先后顺序,也可以不具有先后顺序,下面将针对这两个情况,示例性地说明两个SRS资源集与两个TPMI指示域的对应关系。
示例1:假设第一指示信息依次指示SRS资源集0、SRS资源集1,且DCI包括两个TPMI指示域,依次分别是TPMI指示域0、TPMI指示域1,那么SRS资源集0与TPMI指示域0对应,SRS资源集1与TPMI指示域1对应。
示例2:假设第一指示信息依次指示SRS资源集1、SRS资源集0,且DCI包括两个TPMI指示域,依次分别是TPMI指示域0、TPMI指示域1,那么SRS资源集1与TPMI指示域0对应,SRS资源集0与TPMI指示域1对应。
示例3:假设第一指示信息指示SRS资源集0和SRS资源集1,但是这两个SRS资源集之间没有先后顺序,且DCI包括两个TPMI指示域,那么终端设备可以采用SRS资源集与TPMI指示域之间的默认关系,如该默认关系是SRS资源集0与TPMI指示域0对应,SRS资源集1与TPMI指示域1对应。或者,SRS资源集1与TPMI指示域0对应,SRS资源集0与TPMI指示域1对应。
示例4:假设第一指示信息指示SRS资源集0和SRS资源集1,但是这两个SRS资源集之间没有先后顺序,且DCI包括两个TPMI指示域,那么这时网络设备还可以在该DCI中携带第三指示信息,以指示两个SRS资源集与两个TPMI指示域之间的一一对应关系。如该一一对应关系是SRS资源集0与TPMI指示域0对应,SRS资源集1与TPMI指示域1对应。或者,SRS资源集1与TPMI指示域0对应,SRS资源集0与TPMI指示域1对应。
应理解的是,上述第二指示信息和第三指示信息可以为同一个指示信息,也可以为不同的指示信息,例如:上述第二指示信息和第三指示信息是DCI中同一个指示域的信息,即该信息可以同时指示两个SRS资源集与两个SRI指示域的一一对应关系,以及,指示两个SRS资源集与两个TPMI指示域的一一对应关系。示例性的,假设该指示域上的信息取值为0,则表示SRS资源集0与SRI指示域0、TPMI指示域0对应,SRS资源集1与SRI指示域1、TPMI指示域1对应。假设该指示域上的信息取值为1,则表示SRS 资源集0与SRI指示域1、TPMI指示域1对应,SRS资源集1与SRI指示域0、TPMI指示域0对应。
如上所述,当第一指示信息指示两个SRS资源集时,终端设备进行多TRP上行重复传输,而两个SRS资源集与上行重复传输之间的映射关系可以是以下任一项,但不限于此:
可实现方式一:若第一指示信息依次指示第一SRS资源集和第二SRS资源集,则第一SRS资源集与多TRP上行重复传输中奇数次的上行重复传输对应,第二SRS资源集与多TRP上行重复传输中偶数次的上行重复传输对应。

可实现方式四:若第一指示信息指示两个SRS资源集,则DCI还包括第五指示信息,用于指示两个SRS资源集中的第二SRS资源集与奇数次的上行重复传输对应,两个SRS资源集中的第一SRS资源集与偶数次的上行重复传输对应。
可实现方式五:多TRP上行重复传输中从第一次上行重复传输开始,每连续M个上行重复传输为一组,多TRP上行重复传输包括多组连续M个上行重复传输,M为大于1的整数。若第一指示信息依次指示第一SRS资源集和第二SRS资源集,则第一SRS资源集与多组连续M个上行重复传输中奇数组的上行重复传输对应,第二SRS资源集与多组连续M个上行重复传输中偶数组的上行重复传输映射对应。
可实现方式六:多TRP上行重复传输中从第一次上行重复传输开始,每连续M个上行重复传输为一组,多TRP上行重复传输包括多组连续M个上行重复传输,M为大于1的整数。若第一指示信息依次指示第二SRS资源集和第一SRS资源集,则第二SRS资源集与奇数组的上行重复传输对应,第一SRS资源集与偶数组的上行重复传输映射对应。
可实现方式七:多TRP上行重复传输中从第一次上行重复传输开始,每连续M个上行重复传输为一组,多TRP上行重复传输包括多组连续M个上行重复传输,M为大于1的整数。若第一指示信息依次指示两个SRS资源集,则DCI还包括第六指示信息,用于指示两个SRS资源集中的第一SRS资源集与多组连续M个上行重复传输中奇数组的上行重复传输对应,两个SRS资源集中的第二SRS资源集与多组连续M个上行重复传输中偶数组的上行重复传输映射对应。
可实现方式八:多TRP上行重复传输中从第一次上行重复传输开始,每连续M个上行重复传输为一组,多TRP上行重复传输包括多组连续M个上行重复传输,M为大于1的整数。若第一指示信息依次指示两个SRS资源集,则DCI还包括第七指示信息,用于指示两个SRS资源集中的第二SRS资源集与奇数组的上行重复传输对应,两个SRS资源集中的第一SRS资源集与偶数组的上行重复传输映射对应。
可选的,可实现方式一至八中的上行重复传输是名义(nominal)上的上行重复传输或者实际(actual)上的上行重复传输。
应理解的是,多TRP上行重复传输包括:第一次上行重复传输、第二次上行重复传输……
应理解的是,上述可实现方式一至可实现方式八所提供的SRS资源集与上次重复传输之间的映射关系,也被理解为SRS资源集按照波束映射方式(Beam mapping pattern)映射至上行重复传输。其中,可实现方式一至可实现方式四采用的一类波束映射方式,下面简称为波束映射方式一,可实现方式五至可实现方式八采用的另一类波束映射方式, 下面简称为波束映射方式二。
下面对波束映射方式一和波束映射方式二进行说明:
图5为本申请实施例提供的波束映射方式一的示意图,如图5所示,多TRP上行重复传输中的第一次上行重复传输对应多TRP中的TRP 0,第二次上行重复传输对应多TRP中的TRP 1,第三次上行重复传输对应多TRP中的TRP 0,第四次上行重复传输对应多TRP中的TRP 1,以此类推,将对应于TRP 0的上行重复传输用0表示,将对应于TRP 1的上行重复传输用1表示,假设总共存在8次上行重复传输,那么这8次上行重复传输可以用01010101表示。
图6为本申请实施例提供的波束映射方式二的示意图,如图6所示,多TRP上行重复传输中的第一次上行重复传输对应多TRP中的TRP 0,第二次上行重复传输对应多TRP中的TRP 0,第三次上行重复传输对应多TRP中的TRP 1,第四次上行重复传输对应多TRP中的TRP 1,以此类推,将对应于TRP 0的上行重复传输用0表示,将对应于TRP 1的上行重复传输用1表示,假设总共存在8次上行重复传输,那么这8次上行重复传输可以用00110011表示。
