网络设备与终端之间可以各自使用一或多根天线进行多输入多输出(Multi Input Multi Output,MIMO)传输,MIMO传输可以是单用户MIMO(Single User MIMO,SU-MIMO)或多用户MIMO(Multiple User MIMO,MU-MIMO)。根据根天线组合的形态和数量,MIMO传输可以是2D-MIMO、3D-MIMO、FD-MIMO或massive-MIMO,也可以是分集传输或预编码传输或波束赋形传输等。
下面首先对本公开实施例提供的方案涉及的内容进行介绍。
其中,本公开实施例涉及的下行信号的多种传输方案包括:
(1)空分复用(Spatial Division Multiplexing,SDM)方案1a;
(2)频分复用(Frequency Division Multiplexing,FDM)方案2a;
(3)FDM方案2b;
(4)时分复用(Time Division Multiplexing,TDM)方案3;
(5)TDM方案4;
(6)基本方案;
(7)TDM方案4的回退方案。
传输方案(1)-(5)的共同点包括:
(1)下行信号的层(layer)与解调参考信号(DeModulation-Reference Signal,DMRS)端口一一映射;
(2)下行信号及其DMRS端口的准共址QCL(quasi co-location)信息根据一个包括两个传输配置指示(Transmission Configuration Indicator,TCI)state(状态)的TCI codepoint(码点)确定,这个TCI codepoint可以被称为下行信号对应的TCI codepoint。该TCI codepoin关联的TCI state中的信息为所述下行信号的QCL信息。该TCI codepoin关联的TCI state中的参考信号为所述下行信号的QCL参考信号。
传输方案传输方案(1)-(5)的不同点在于传输配置指示状态(Transmission Configuration Indication state,TCI state)与下行信号的DMRS端口在时频资源上的关联关系不同。
一个TCI state中可以包括TCI state的标识,QCL类型,以及QCL类型对应的参考信号。例如,一种配置TCI state的方式:TCI state里包括QCL类型信息(例如qcl-Type1,通过QCL-Info指示)和TCI state的标识(例如tci-StateId,通过TCI-StateId指示)。每个QCL类型信息通过QCL-Info指示,QCL-Info里包括具体的QCL类型(qcl-Type,取值可以为{typeA,typeB,typeC,typeD}中的一项,其中type A包括信道大尺度参数{平均时延,时延扩展,多普勒频移,多普勒扩展},type B包括信道大尺度参数{多普勒频移,多普勒扩展},type C包括信道大尺度参数{平均时延,多普勒频移},type D包括信道大尺度参数{接收空间参数}),参考信号类型(如csi-rs,SSB)、参考信号标识(如NZP-CSI-RS-ResourceId,SSB-Index)、参考信号所在的小区(cell)和带宽部分BWP(bwp-Id)。其中,同一个QCL-Info中的参考信号与QCL类型相关联,即,一个QCL-Info中的参考信号为这个QCL-Info指示的QCL类型所对应的参考信号。另外,一些确定下行信号的QCL参考信号的方式有:
当无线资源控制RRC信令为下行信号只配置了一个TCI state时,下行信号传输对应的TCI state为RRC信令配置的TCI state,该TCI state中包括的参考信号为下行信号的QCL参考信号。
当RRC信令为下行信号配置了多个TCI state,且没有配置通过DCI指示 下行信号的TCI时,下行信号传输对应的TCI state可以通过媒体接入控制控制单元MAC-CE信令指示。一种实现方式为:RRC信令配置多个TCI state,MAC-CE信令激活一个TCI codepoint,该TCI codepoint对应于RRC配置的一个或多个TCI state,下行信号对应的TCI codepoint为MAC-CE激活的TCI codepoint。该TCI codepoin关联的TCI state中包括的参考信号为下行信号的QCL参考信号。
当RRC信令配置通过DCI指示下行信号的TCI时,PDSCH传输对应的TCI codepoint通过DCI中的TCI域指示。一种实现方式为:RRC信令配置多个TCI state,MAC-CE信令从中为DCI中的TCI域激活和去激活配置了多个TCI codepoint,每个TCI codepoint对应于一个或多个TCI state,DCI中的TCI域从MAC-CE激活的多个TCI codepoint中选择一个TCI codepoint作为下行信号对应的TCI codepoint。下行信号对应的TCI codepoin关联的TCI state中包括的参考信号为下行信号的QCL参考信号。
可选的,上述DCI为调度所述下行信号的DCI。
在本公开实施例中,下行信号可以是下行共享信道PDSCH信号,下行控制信道PDCCH信号,SSB等。在下文中为了表述方便,在多处以PDSCH信号为例进行阐述。
关于上述各传输方案,具体如下:
(1)SDM方案1a:
PDSCH的DMRS端口在两个码分复用(Code Division Multiplexing,CDM)组中,其中一个CDM组的DMRS端口与一个TCI state关联,另一个CDM组的DMRS端口与另外一个TCI state关联。
(2)FDM方案2a:
同一个PDSCH传输机会(PDSCH transmission occasion)的传输块(Transport Block,TB)关联两个TCI state,两个TCI state分别关联于一组资源,两个TCI state关联的资源在频域上不重叠。这里的一个TCI state关联于一组资源是指PDSCH的DMRS端口在这组资源上与这个TCI state相关联。
(2)FDM方案2b:
同一个PDSCH TB通过两个PDSCH transmission occasions传输,两个 PDSCH transmission occasion各自关联一个TCI state,且两个PDSCH transmission occasion在频域上不重叠。
(3)TDM方案3:PDSCH transmission occasion的个数取决于为该PDSCH被指示的TCI codepoint包括的TCI state的个数:
1)当被指示了包括两个TCI state的TCI codepoint时,PDSCH通过两个PDSCH transmission occasion在一个给定的时隙内传输,每个PDSCH transmission occasion与一个TCI state关联,且两个TCI state关联的PDSCH transmission occasion在时域上不重叠(TDM 3)。
2)当被指示了包括一个TCI state的TCI codepoint时,一个TB通过一个PDSCH transmission occasion传输,该TCI state与该PDSCH transmission occasion关联(TDM 3回退到基本传输方案)。
(4)TDM方案4:PDSCH通过多个PDSCH transmission occasion传输。
1)当被指示了包括两个TCI state的TCI codepoint时,PDSCH通过多个PDSCH transmission occasion传输,不同的PDSCH transmission occasion传输在不同的时隙上,每个TCI state关联于一个或多个PDSCH transmission occasion,且两个TCI state分别与不同的PDSCH transmission occasion关联(TDM 4)。
2)当被指示了包括一个TCI state的TCI codepoint时,PDSCH通过多个PDSCH transmission occasion传输,不同的PDSCH transmission occasion传输在不同的时隙上,所有的PDSCH transmission occasion都与该TCI state相关联(TDM 4的回退方案)。
在上述各方案中,可选的,当一个PDSCH transmission occasion与一个TCI state相关联时,这个PDSCH的transmission occasion对应的DMRS端口也与该TCI state相关联。可选的,当PDSCH的一个TB块与一个TCI state相关联时,这个PDSCH的这个TB对应的DMRS端口也与该TCI state相关联。
基本传输方案是指PDSCH只与一个TCI state关联。
在本公开的实施例中,一个DMRS端口与一个TCI state关联是指该TCI state被用来指示该DMRS端口的QCL信息。一个TCI state关联一组资源是 指这个TCI state用于指示这组资源上的DMRS端口和/或PDSCH层的QCL信息。一个PDSCH传输机会关联一个TCI state是指这个TCI state被用来指示该PDSCH传输机会中PDSCH层和/或PDSCH的DMRS端口的QCL信息。
可选的,上述某个TCI state被用来指示一个DMRS端口的QCL信息是指这个TCI state用来指示与该DMRS端口具有QCL关系的参考信号。上述某个TCI state被用来指示一个信号的层的QCL信息是指这个TCI state用来指示与该层具有QCL关系的参考信号。
PDSCH的基本传输方案为:PDSCH的所有的DMRS端口关联到同一个TCI state,且该TCI state中所有的QCL类型都只有一个关联的参考信号。
另外,在高速移动的典型应用场景,比如高速传输(high speed transmission,HST)场景中,多个传输接收点(Transmission/Receiption Point,TRP;可以是多个射频拉远头(Remote Radio Head,RRH))可以同时向高速移动的终端设备发送下行信号。其中,可以通过一个同时经多个TRP发送的准共址(Quasi Co-Location,QCL)参考信号确定下行信号的信道的多普勒频移等大尺度参数,并根据该大尺度参数,确定出信道估计插值系数,从而对信道进行估计。
进一步的,网络设备可以向终端发送下行信号的DMRS端口的QCL信息,QCL信息中包括QCL类型和各个QCL类型关联的参考信号。其中,一个QCL类型包含了一种或多种信道大尺度参数,终端通过这个QCL类型对应的参考信号的信道的这些大尺度参数可以推出DMRS端口的信道的这些大尺度参数,从而可以更好地进行下行信号的信道估计。为了描述方便,在一个天线端口的信道的大尺度参数A可以通过另一个天线端口的信道的大尺度参数A推测出来时,认为这两个天线端口具有关于信道大尺度参数A的QCL关系。类似的,在一个信号的一个层的信道的大尺度参数A可以通过一个天线端口的信道的大尺度参数A推测出来时,认为这个层与该天线端口具有关于信道大尺度参数A的QCL关系。
此外,考虑到由于终端设备是高速移动的,当TRP的位置不同时,各个TRP对应的路径可能来自相反的方向,从而使得多个径的多普勒频移不同,因此,通过一个同时从多个TRP发送的参考信号无法准确获得下行信道的多普勒频移和多普勒扩展,使得信道估计结果不准,从而影响下行信号的解调 性能。为了提高下行信号的解调性能,可以考虑每个TRP发送自己对应的参考信号,终端基于多个参考信号共同确定出下行信道的信道估计系数,从而对下行信道进行更好的估计。在这种方案下,PDSCH的一个数据层和/或一个DMRS端口与多个参考信号具有关于至少一个信道大尺度参数的QCL(准共址)关系。
基于以上,本公开实施例提供了信息处理方法、装置、终端及网络设备,用以解决相关技术中系统中存在多种Multi-TRP传输方案时无法准确的确定具体的传输方案的问题。其中,信息处理方法、装置、终端及网络设备是基于同一构思的,由于信息处理方法、装置、终端及网络设备解决问题的原理相似,因此信息处理方法、装置、终端及网络设备的实施可以相互参见,重复之处不再赘述。

针对上述技术问题,本公开实施例提供了一种信息处理方法,在此说明,本公开实施例提供的方案适用的系统包括但不限于NR系统,LTE系统,6G系统,以及它们演进版本的系统等。
SDM 1c的传输方案包括:
PDSCH的数据层和/或DMRS端口与多个参考信号具有关于至少一个信道大尺度参数的QCL关系。可选的,具体为PDSCH的所有数据层和/或DMRS端口与多个参考信号具有关于至少一个信道大尺度参数的QCL关系。
可选的,具体为PDSCH的一个数据层和/或一个DMRS端口与多个参考信号具有关于至少一个信道大尺度参数的QCL关系。
可选的,具体为PDSCH的一个数据层与多个参考信号具有关于同一个信道大尺度参数的QCL关系和/或PDSCH的一个DMRS端口与多个参考信号具有关于同一个信道大尺度参数的QCL关系。
可选的,具体为PDSCH的任意一个数据层与多个参考信号具有关于同一个信道大尺度参数的QCL关系和/或PDSCH的任意一个DMRS端口与多 个参考信号具有关于同一个信道大尺度参数的QCL关系。
可选的,具体为PDSCH的所有数据层都与多个参考信号具有关于同一个信道大尺度参数的QCL关系和/或PDSCH的所有DMRS端口与多个参考信号具有关于同一个信道大尺度参数的QCL关系。举例来说,PDSCH共有2个DMRS端口(DMRS端口1与DMRS端口2),则这2个DMRS端口各自与多个参考信号具有关于信道大尺度参数A的QCL关系。例如,DMRS端口1与参考信号RS 1和参考信号RS 2具有关于信道大尺度参数A的QCL关系;DMRS端口2与参考信号RS 1和参考信号RS 2具有关于信道大尺度参数A的QCL关系。可选的,PDSCH的所有DMRS端口都与相同的多个参考信号具有关于同一个信道大尺度参数的QCL关系。仍以PDSCH共有2个DMRS端口(DMRS端口1与DMRS端口2)为例,这两个2个DMRS端口都与参考信号RS 1和参考信号RS 2具有关于信道大尺度参数A的QCL关系。
可选的,网络设备通过TCI指示信息向UE指示PDSCH的数据层/DMRS端口与参考信号关于信道大尺度参数的QCL关系。一个TCI指示信息指示一个TCI codepoint,该TCI codepoint可以与一个或多个TCI state相关联,每个TCI state中包括一个或多个QCL类型和与各个QCL类型对应的参考信号。
具体的:
(1)可选的,对于SDM 1c,TCI指示信息指示的TCI codepoint与多个TCI state相关联,所述多个TCI state包括的QCL类型相同或不同。PDSCH的数据层/DMRS端口与这些TCI state指示的各个参考信号具有关于各个参考信号所对应的QCL类型的QCL关系。可选的,PDSCH的所有数据层/DMRS端口与这些TCI state指示的各个参考信号具有关于各个参考信号所对应的QCL类型的QCL关系。可选的,PDSCH的任意一个数据层/DMRS端口都与这些TCI state指示的各个参考信号具有关于各个参考信号所对应的QCL类型的QCL关系。可选的,所述多个TCI state中至少两个TCI state中包括一个相同的QCL类型。PDSCH的数据层/DMRS端口与所述至少两个TCI state中的包括的所述一个相同的QCL类型对应的参考信号具有关于所述一个相同的QCL类型的QCL关系。
其中,所述多个TCI state包括的QCL类型相同或不同:
可选的,多个TCI state中至少有两个TCI state包括的QCL类型中对应了至少一个相同的信道大尺度参数。例如,两个TCI state中一个TCI state中包括QCL类型A,QCL类型A对应的信道大尺度参数为{平均时延,时延扩展,多普勒频移,多普勒扩展},另一个TCI state中包括QCL类型B,QCL类型B对应的信道大尺度参数为{多普勒频移,多普勒扩展},由于这两个TCI state包括的QCL类型中都对应了多普勒频移和多普勒扩展,即存在两个相同的信道大尺度参数,因此满足“多个TCI state中至少有两个TCI state包括的QCL类型中对应了至少一个相同的信道大尺度参数。”
再例如,两个TCI state中一个TCI state中只包括QCL类型B,QCL类型B对应的信道大尺度参数为{多普勒频移,多普勒扩展},另一个TCI state中只包括QCL类型D,QCL类型D对应的信道大尺度参数为{空间接收参数},由于这两个TCI state包括的QCL类型全部对应于不同的信道大尺度参数,因此不满足“多个TCI state中至少有两个TCI state包括的QCL类型中对应了至少一个相同的信道大尺度参数。”
(2)可选的,对于SDM 1c,TCI指示信息指示的TCI codepoint与一个或多个TCI state相关联,其中至少一个TCI state包括的某个QCL类型对应了多个参考信号。PDSCH的一个数据层/DMRS端口与这个QCL类型对应的多个参考信号具有关于这个QCL类型的QCL关系。可选的,PDSCH的所有数据层/DMRS端口与这个QCL类型对应的多个参考信号具有关于这个QCL类型的QCL关系。可选的,PDSCH的任一数据层和/或DMRS端口与这个QCL类型对应的多个参考信号具有关于这个QCL类型的QCL关系。
本公开实施例提供的方案主要涉及:根据信令(RRC信令、媒体接入控制控制单元MAC-CE信令或下行控制信息DCI)的配置(对应于上述传输模式配置信息)、PDSCH的DMRS端口的配置(对应于上述DMRS端口指示信息,包含QCL指示信息,QCL指示信息能够指示QCL类型信息,和/或TCI state的个数信息;这里的配置也可以是DCI信令指示的信息;例如调度所述PDSCH的DCI里指示的天线端口antenna port;这里的配置可以是通过一个信令或多个信令指示的信息,例如,一部分信息通过RRC信令指示,另一部分信息通过DCI指示)、网络设备关于PDSCH的时域资源分配TDRA指示(对 应于上述TDRA指示信息)、和/或UE是否处于高铁场景和/或频率预补偿场景的指示信息(对应于上述场景指示信息),确定是否为SDM 1c(也可理解为确定要采用的第一信号的传输方案是否为SDM 1c)。
具体可实现为采用如下方式中的至少一种确定是否为SDM 1c(关于“关联至少2个TCI state”以对应的TCI codepoint包括2或更多个TCI state为例,上述第二传输方案的参数以上述TDM 4的重复次数的配置为例,传输模式以重复传输模式为例,信令以RRC信令为例):
方式一(根据PDSCH的DMRS端口的配置以及关于PDSCH的TDRA指示确定):如果调度PDSCH的DCI的TDRA域中没有指示包括对应于TDM 4的重复次数的配置(也可理解为TDM 4的配置参数),该PDSCH(和/或该PDSCH的DMRS端口)对应的TCI codepoint包括2或更多个TCI state,且该PDSCH的所有DMRS端口都在一个CDM组内,则该PDSCH的传输为SDM 1c的传输方案。
方式二(根据RRC信令的配置确定):如果用来指示PDSCH的重复传输模式的RRC参数(例如,RRC参数RepetitionScheme(重复方案)-r16,关于“RepetitionScheme-r16”也可称为“RepetitionScheme”,以下以称为“RepetitionScheme-r16”为例,重复传输模式也可以是多传输点M-TRP传输模式)被配置为SDM 1c对应的取值,则该PDSCH的传输为SDM 1c的传输方案。
方式三(根据RRC信令的配置确定):如果用来指示PDSCH的重复传输模式的RRC参数(例如,RRC参数RepetitionScheme-r16)被配置为SDM 1c对应的取值,且该PDSCH对应的TCI codepoint包括2个或更多个TCI state,则该PDSCH的传输为SDM 1c的传输方案。
可选的,UE还按照如下方式判断是否为SDM 1a:
如果调度PDSCH的DCI的TDRA域中没有指示包括对应于TDM 4的重复次数的配置且用来指示PDSCH的重复传输模式的RRC参数(例如,RRC参数RepetitionScheme-r16)没有被配置为SDM 1c对应的取值,该PDSCH对应的TCI codepoint包括2个TCI state,且该PDSCH的DMRS端口在2个CDM组,则该PDSCH的传输为SDM 1a的传输方案。
方式四(根据RRC信令的配置以及PDSCH的DMRS端口的配置确定):如果用来指示PDSCH的重复传输模式的RRC参数(例如,RRC参数RepetitionScheme(重复方案)-r16)被配置为SDM 1c对应的取值,且该PDSCH对应的TCI codepoint包括2个或更多个TCI state,且该PDSCH的所有DMRS端口都在一个CDM组内,则该PDSCH的传输为SDM 1c的传输方案。
方式五(根据PDSCH的DMRS端口的配置确定):如果PDSCH对应的TCI codepoint中至少包括1个满足以下条件的TCI state,则该PDSCH的传输为SDM 1c的传输方案;
条件:至少一个QCL类型关联了多个参考信号。
方式六(根据关于PDSCH的TDRA指示和PDSCH的DMRS端口的配置确定):如果调度PDSCH的DCI的TDRA域中没有指示包括了对应于TDM 4的重复次数的配置,且该PDSCH对应的TCI codepoint至少包括1个满足以下条件的TCI state,则该PDSCH的传输为SDM 1c的传输方案;
条件:至少一个QCL类型关联了多个参考信号。
比如,TCI state 1:

2)如果为1,则UE判断是否存在用来指示重复传输方案的参数(例如,为RRC参数RepetitionScheme-r16):
如果不存在,则为SDM 1c;
如果存在,则根据该参数的取值确定具体的传输方案:
如果指示了FDM 2a(例如,RRC参数RepetitionScheme-r16的取值为FDMSchemeA),则为FDM 2a;
如果指示了FDM 2b(例如,RRC参数RepetitionScheme-r16的取值为FDMSchemeB),则为FDM 2b;
如果指示了TDM 3(例如,RRC参数RepetitionScheme-r16的取值为TDMSchemeA),则为TDM 3。

(2)如果为否,判断PDSCH对应的TCI codepoint中包括的TCI state的数目(可选的,PDSCH对应的TCI codepoint通过调度该PDSCH的DCI中的'Transmission Configuration Indication'域指示):
1)如果为1,为基本传输方案;
2)如果为2,则判断PDSCH的DMRS端口所在的CDM组的数目;若为1,则为SDM 1c;若为2,则为SDM 1a;
3.如果存在用来指示重复传输方案的参数,UE判断PDSCH对应的TCI codepoint中包括的TCI state的数目(可选的,PDSCH对应的TCI codepoint通过调度该PDSCH的DCI中的'Transmission Configuration Indication'域指示):

基于举例方式2的实现举例2:
基站通过DCI指示UE进行PDSCH的接收。
UE判断RRC信令中是否存在用来指示PDSCH的重复传输模式的参数,并判断DCI中的TCI域指示的TCI codepoint对应的TCI state的个数和DCI中的antenna port域指示的DMRS端口所在的CDM组。如果存在用来指示PDSCH的重复传输模式的参数且该参数被配置为SDM 1c,上述TCI codepoint对应的TCI state的个数为2,antenna port域指示的所有的DMRS端口都在一个CDM组内,则UE确定PDSCH的传输模式为SDM 1c,即只有一个PDSCH transmission occasion,且在PDSCH transmission occasion所对应的时频资源上PDSCH的DMRS端口与上述TCI codepoint对应的所有TCI state相关联。

2)如果为2,则为SDM 1a;
3.如果存在用来指示重复传输方案的参数,UE判断PDSCH对应的TCI  codepoint中包括的TCI state的数目(可选的,PDSCH对应的TCI codepoint通过调度该PDSCH的DCI中的'Transmission Configuration Indication'域指示):
(1)如果为1,为基本传输方案;
(2)如果>1,比如为2,UE判断PDSCH的DMRS端口所在的CDM组的数目:
1)如果为2,则用来指示重复传输模式的参数的取值是否对应于SDM 1c,若是,则为SDM 1c,否则,为SDM 1a。
2)如果为1,则判断存在用来指示重复传输方案的参数(例如,为RRC参数RepetitionScheme-r16)的取值:
如果指示了FDM 2a(例如,RRC参数RepetitionScheme-r16的取值为FDMSchemeA),则为FDM 2a;
如果指示了FDM 2b(例如,RRC参数RepetitionScheme-r16的取值为FDMSchemeB),则为FDM 2b;
如果指示了TDM3(例如,RRC参数RepetitionScheme-r16的取值为TDMSchemeA),则为TDM 3;
如果指示了SDM 1c(例如,RRC参数RepetitionScheme-r16的取值为SDMSchemeA),则为SDM 1c。
对应于上述方式三的举例方式3:可选的,SDM 1c的传输方案还包括:同一个TB通过一个PDSCH transmission occasion传输,PDSCH的所有DMRS端口都与包含在同一个TCI codepoint里的多个TCI state相关联,PDSCH的所有DMRS端口占用的PRB(Physical resource block,物理资源块)相同。可选的,所述多个TCI state具体为2个TCI state。
SDM 1c的指示复用用来指示PDSCH的重复传输模式的RRC参数(例如,RRC参数RepetitionScheme-r16),即为该参数增加一个候选值,例如,增加候选值SDMSchemeA或SDMSchemeC。
即SDM 1c的确定方式为:
如果用来指示PDSCH的重复传输模式的RRC参数(例如,RRC参数RepetitionScheme-r16)被配置为SDM 1c对应的取值,则该PDSCH的传输为SDM 1c的传输方案。
可选的,如果用来指示PDSCH的重复传输模式的RRC参数(例如,RRC参数RepetitionScheme-r16)被配置为SDM 1c对应的取值,且该PDSCH对应的TCI codepoint包括2个或更多个TCI state,则该PDSCH的传输为SDM 1c的传输方案。
针对以上,UE可按照如下方式判断是否为SDM 1a:
如果调度PDSCH的DCI的TDRA域中没有指示对应于RepetitionNumber-r16的配置且用来指示PDSCH的重复传输模式的RRC参数(例如,RRC参数RepetitionScheme-r16)没有被配置为SDM 1c对应的取值,该PDSCH对应的TCI codepoint包括2个TCI state,且该PDSCH的DMRS端口在2个CDM组,则该PDSCH的传输为SDM 1a的传输方案。
基于举例方式3的实现举例3:基站通过DCI指示UE进行PDSCH的接收。
UE判断RRC信令中是否存在用来指示PDSCH的重复传输模式的参数,并判断DCI中的TCI域指示的TCI codepoint对应的TCI state的个数。如果存在用来指示PDSCH的重复传输模式的参数且该参数被配置为SDM 1c,上述TCI codepoint对应的TCI state的个数为2,则UE确定PDSCH的传输模式为SDM 1c,即只有一个PDSCH transmission occasion,且在PDSCH transmission occasion所对应的时频资源上PDSCH的DMRS端口与上述TCI codepoint对应的所有TCI state相关联。
UE根据所确定的PDSCH的传输模式接收PDSCH。
可选的,UE确定各传输方案的判断条件如下表所示:
被指示的TCI codepoint包括的TCI state个数
DMRS端口的CDM组个数
UE是否被配置了RepetitionNumber-r16
(重复传输次数)UE是否被配置了RepetitionScheme-r16
(传输方案配置)UE Behavior
(UE行为)
1≥1 是,且DCI的TDRA域中没有指示对应于RepetitionNumber-r16的配置/否 否 基本传输方案

2 1 是,且DCI的TDRA域中指示了对应于RepetitionNumber-r16的配置否TDM 4
2 2 是,且DCI的TDRA域中没有指示对应于RepetitionNumber-r16的配置否SDM 1a
2 2 否 是,且取值不对应于SDM 1c(例如,为'SDMSchemeA')/否SDM 1a
2 1 否 是,且为'TDMSchemeA'FDM 2a
2 1 否 是,且为'FDMSchemeB'FDM 2b
2 1 否 是,且为'TDMSchemeA'TDM 3
2≥1 否 是,且为对应于SDM 1c的取值(例如,为'SDMSchemeA',也可能是另外的取值表达方式)SDM 1c

1)是,为SDM 1c;
2)否或不存在用来指示重复传输方案的参数,为SDM 1a;
(2)如果为1,则UE判断DCI中的TDRA是否指示了包括TDM 4对 应的重传次数;若是,则为TDM 4,若否,则判断用来指示重复传输方案的参数(例如,为RRC参数RepetitionScheme-r16)的取值指示的内容:
如果指示了FDM 2a(例如,RRC参数RepetitionScheme-r16的取值为FDMSchemeA),则为FDM 2a;
如果指示了FDM 2b(例如,RRC参数RepetitionScheme-r16的取值为FDMSchemeB),则为FDM 2b;

(2)否则,UE判断PDSCH的DMRS端口所在的CDM组的数目:
1)如果为2,则判断存在用来指示重复传输方案的参数(例如,为RRC参数RepetitionScheme-r16)的取值是否对应于SDM 1c:
如果对应于SDM 1c,为SDM 1c;
如果不存在或取值不对应于SDM 1c,为SDM 1a。
2)如果为1,则判断存在用来指示重复传输方案的参数(例如,为RRC 参数RepetitionScheme-r16)的取值:

如果指示了FDM 2b(例如,RRC参数RepetitionScheme-r16的取值为FDMSchemeB),则为FDM 2b;
如果指示了TDM3(例如,RRC参数RepetitionScheme-r16的取值为TDMSchemeA),则为TDM 3;
如果指示了SDM 1c(例如,RRC参数RepetitionScheme-r16的取值为SDMSchemeA),则为SDM 1c。
另一种可能的UE判断各种传输方案的流程图如图12所示,其中:
UE判断RRC信令中是否存在TDM 4对应的重传次数的配置(例如,是否存在RRC参数repetitionNumber-r16)或用来指示重复传输方案的参数(例如,为RRC参数RepetitionScheme-r16):
1.如果都不存在,则为基本传输方案;
2.如果存在TDM 4对应的重传次数的配置(例如,存在RRC参数repetitionNumber-r16);则判断调度PDSCH的DCI中的TDRA域("Time domain resource assignment'域)是否指示了包括TDM 4对应的重传次数(例如,为RRC参数repetitionNumber-r16)的配置:
(1)是,则判断PDSCH对应的TCI codepoint中包括的TCI state的数目(可选的,PDSCH对应的TCI codepoint通过调度该PDSCH的DCI中的'Transmission Configuration Indication'域指示):
1)如果为2,则为TDM 4;
2)如果为1,则为TDM 4的回退传输方案;
(2)如果为否,判断PDSCH对应的TCI codepoint中包括的TCI state的数目(可选的,PDSCH对应的TCI codepoint通过调度该PDSCH的DCI中的'Transmission Configuration Indication'域指示):
1)如果为1,为基本传输方案;
2)如果为2,则为SDM 1a;
3.如果存在用来指示重复传输方案的参数,UE判断PDSCH对应的TCI  codepoint中包括的TCI state的数目(可选的,PDSCH对应的TCI codepoint通过调度该PDSCH的DCI中的'Transmission Configuration Indication'域指示):
(1)如果为1,为基本传输方案;
(2)如果>1,比如为2,UE判断PDSCH的DMRS端口所在的CDM组的数目:
1)如果为2,则判断存在用来指示重复传输方案的参数(例如,为RRC参数RepetitionScheme-r16)的取值是否对应于SDM 1c:
如果对应于SDM 1c,为SDM 1c;
如果不存在或取值不对应于SDM 1c,为SDM 1a。
2)如果为1,则判断存在用来指示重复传输方案的参数(例如,为RRC参数RepetitionScheme-r16)的取值:
如果指示了FDM 2a(例如,RRC参数RepetitionScheme-r16的取值为FDMSchemeA),则为FDM 2a;
如果指示了FDM 2b(例如,RRC参数RepetitionScheme-r16的取值为FDMSchemeB),则为FDM 2b;
如果指示了TDM3(例如,RRC参数RepetitionScheme-r16的取值为TDMSchemeA),则为TDM 3;
如果指示了SDM 1c(例如,RRC参数RepetitionScheme-r16的取值为SDMSchemeA),则为SDM 1c。
对应于上述方式五至九的举例方式4:通过TCI state中同一个QCL类型关联的参考信号的数目确定是否是SDM 1c的传输模式。
可选的,SDM 1c的传输方案还包括:同一个TB通过一个PDSCH transmission occasion传输,PDSCH的DMRS端口在一个或多个CDM组内且占用的PRB(Physical resource block,物理资源块)相同,PDSCH的DMRS端口与被指示的TCI codepoint里的TCI state相关联,至少一个TCI state中至少一个QCL类型关联了两个或更多个参考信号。
可选的,在为SDM 1c的传输方案时,PDSCH被指示的TCI codepoint中只包括一个TCI state。
此时,通过判断PDSCH被指示的TCI state中的参考信号的配置来判断 是否为SDM 1c的方案。
即SDM 1c的确定方式为以下中的一种:
PDSCH对应的TCI codepoint中至少包括1个满足以下条件的TCI state,则该PDSCH的传输为SDM 1c的传输方案:至少一个QCL类型关联了多个参考信号;
如果调度PDSCH的DCI的TDRA域中没有指示对应于RepetitionNumber-r16的配置,且该PDSCH对应的TCI codepoint至少包括1个满足以下条件的TCI state,则该PDSCH的传输为SDM 1c的传输方案:至少一个QCL类型关联了多个参考信号。
基于举例方式4的实现举例4:基站通过DCI指示UE进行PDSCH的接收。
UE判断DCI中的TCI域指示的TCI codepoint对应的TCI state中的QCL类型与参考信号的关联关系。如果存在至少一个QCL类型关联了多个参考信号,则UE确定PDSCH的传输模式为SDM 1c,即只有一个PDSCH transmission occasion,且在PDSCH transmission occasion所对应的时频资源上PDSCH的DMRS端口与上述TCI codepoint对应的所有TCI state相关联。
举例来说,TCI域指示的TCI codepoint关联的一个TCI state包括以下内容:{QCL_type 1:RS1,RS2},即QCL类型1关联了RS 1和RS2这两个参考信号;则UE确定PDSCH的传输模式为SDM 1c。
UE根据所确定的PDSCH的传输模式接收PDSCH。
基于举例方式4的实现举例5:基站通过DCI指示UE进行PDSCH的接收。
UE判断DCI中的TDRA域是否指示了对应于RepetitionNumber-r16的PDSCH-TimeDomainResourceAllocation-r16配置,并判断DCI中的TCI域指示的TCI codepoint对应的TCI state中的QCL类型与参考信号的关联关系。如果调度PDSCH的DCI的TDRA域中没有指示对应于RepetitionNumber-r16的配置,且存在至少一个QCL类型关联了多个参考信号,则UE确定PDSCH的传输模式为SDM 1c,即只有一个PDSCH transmission occasion,且在PDSCH transmission occasion所对应的时频资源上PDSCH的DMRS端口与上 述TCI codepoint对应的所有TCI state相关联。
UE根据所确定的PDSCH的传输模式接收PDSCH。
在本举例中,每个TCI state中包括一个或多个QCL类型,每个QCL类型关联一个或多个参考信号。
一个DMRS端口与TCI state关联,是指传输该DMRS端口的信道与该TCI state中与某个QCL类型相对应的大尺度参数可以通过传输的该TCI state中与该QCL类型相关联的参考信号的信道推出。
一些典型的大尺度参数包括:
多普勒频移,多普勒扩展,平均时延,时延扩展,平均增益。
对应于上述方式五至九的举例方式6:通过判断基站为PDSCH指示的QCL类型确定是否为SDM 1c的方案。
基于举例方式6的实现举例6:
基站向终端发送PDSCH的调度信息;并通过DCI中的TCI域向PDSCH指示与之关联的QCL参考信号。如果TCI域指示的TCI codepoint关联了两个TCI state,且这两个TCI state中一个TCI state中至少包括QCL类型{average delay,delay spread}(还可以包括一个或多个其他的QCL类型),另一个TCI state至少包括QCL类型{average delay,delay spread,Doppler shift,Doppler spread}(还可以包括一个或多个其他的QCL类型),则终端确定该PDSCH的传输为SDM 1c的传输方案。
举例7,8:类似于举例6,但QCL类型分别与方式八、九对应,在此不再赘述。
对应于上述方式十和十一的举例9:
基站向终端发送PDSCH的调度信息;并通过RRC信令、MAC-CE信令或DCI中的TCI域向PDSCH指示与之关联的QCL参考信号。
基站通过RRC信令、MAC-CE信令或DCI信令向UE指示UE根据哪个TCI state中的参考信号确定特定大尺度参数对应的信道特性。可选的,特定的大尺度参数为频率特性信道大尺度参数。例如,为多普勒频移和/或多普勒扩展。
如果TCI域指示的TCI codepoint关联了两个TCI state,且这两个TCI state 都至少包括QCL类型{average delay,delay spread,Doppler shift,Doppler spread},则终端确定该PDSCH的传输为SDM 1c的传输方案。
对应于上述方式十一的举例10:
基站向UE指示UE是否处于高铁场景。
基站向终端发送PDSCH的调度信息;并通过RRC信令、MAC-CE信令或DCI中的TCI域向PDSCH指示与之关联的QCL参考信号。
UE接收到基站指示UE处于高铁场景的指示信息,且TCI域指示的TCI codepoint关联了两个TCI state,则终端确定该PDSCH的传输为SDM 1c的传输方案。
对应于上述方式十一的举例11:
基站向UE指示基站是否对下行信号进行频率预补偿。
基站向终端发送PDSCH的调度信息;并通过RRC信令、MAC-CE信令或DCI中的TCI域向PDSCH指示与之关联的QCL参考信号。
UE接收到基站指示基站对下行信号进行频率预补偿(对应于上述“频率预补偿场景”),且TCI域指示的TCI codepoint关联了两个TCI state,则终端确定该PDSCH的传输为SDM 1c的传输方案。
由上可知,本公开实施例提供的方案涉及SDM 1c的确定方式和UE判断各个传输方案的流程;可以准确实现对SDM 1c方案的确定,以及实现与其他Multi-TRP方案的区分,也就保证了系统中存在多种Multi-TRP传输方案时能够准确的确定具体的传输方案。
