为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。
上行共享信道(Physical downlink shared channel,PUSCH)的传输可以包括基于码本(codebook)的传输和基于非码本(noncodebook)的传输。其中,基于码本传输PUSCH的方案可以包括以下步骤:
步骤1、终端设备向网络设备发送用于码本的探测参考信号(Sounding Reference Signal,SRS)。
步骤2、网络设备根据终端设备发送的SRS进行上行信道检测,对终端设备进行资源调度,并确定出PUSCH传输对应的SRS资源,上行传输的层数和预编码矩阵。网络设备通过下行控制信息(Downlink Control Information,DCI)向终端设备指示上述信息。
步骤3、终端设备接收DCI,并按照DCI的指示发送PUSCH。
在基于码本的PUSCH传输方案中,网络设备可以通过DCI中的传输预编码矩阵指示(Transmitted Precoding Matrix Indicator,TPMI)域来指示PUSCH的上行传输层数和预编码矩阵。通过DCI中的SRS资源指示(SRS Resource Indicator,SRI)域来指示SRS资源集中的具体的SRS资源。其中,PUSCH的传输层数和PUSCH的预编码矩阵是采用联合编码的方式指示的。
需要说明的是,对于基于码本的PUSCH传输方案,终端设备可以根据配置的最大传输层数(也可以称为最大秩),即配置的高层参数maxRank/maxMIMO-Layers的值来确定TPMI域的比特数。这样,终端设备可以根据确定出的比特数来得到TPMI域的取值范围,从而确定出TPMI域实际指示的预编码矩阵,以完成PUSCH传输。
另外,基于非码本传输PUSCH可以包括以下步骤:
步骤1、终端设备测量下行参考信号,获得候选的预编码矩阵,利用候选的预编码矩阵对SRS进行预编码之后,向网络设备发送用于非码本的SRS。
步骤2、网络设备根据终端设备发送的SRS进行上行信道检测,对终端设备进行资源调度,并确定出PUSCH传输的beam对应的SRS资源;网络设备通过DCI向终端设备指示上述信息。
步骤3、终端设备接收DCI,并按照DCI的指示传输PUSCH。
其中,在基于非码本的PUSCH传输方案中,网络设备通过DCI中的SRI域向终端设备指示PUSCH传输层数和SRS资源集中的SRS资源。对于基于非码本的PUSCH传输方案,终端设备可以根据配置的最大传输层数,即网络配置的高层参数maxRank/maxMIMO-Layers确定SRI的比特数。 这样,终端设备可以根据确定出的比特数来得到SRI域的取值范围,从而确定出SRI域实际指示的SRS资源集。
为了提高上行传输的可靠性,标准化进程的版本17(R17)中引入了2个TRP/panel/beam的PUSCH传输方案。其中,对于基于码本的PUSCH传输方案,PUSCH重复传输的类型包括:重复类型A(PUSCH repetition type A)和重复传输类型B(PUSCH repetition type B)。
由于PUSCH repetition type A的传输层数限制为1,因此不需要额外指示相位跟踪参考信号(Phase Tracking Reference Signals,PTRS)端口与解调参考信号(Dedicated Demodulation Reference Signals,DMRS)端口的关联关系。
而对于PUSCH repetition type B,传输层数可以大于1层。当maxrank等于2(即最大传输层数为2)时,只需要一个PTRS端口,DCI格式0-1或格式0-2使用2比特用来指示PTRS端口与DMRS端口的关联关系。参考表1所示,2比特可以包括最高有效比特(Most Significant Bit,MSB)和最低有效比特(Least Significant Bit,LSB)分别对应TRP1和TRP2。
表1
从表1可以看出,MSB中的状态0可以用于指示向TRP1发送的PUSCH的PTRS与第一个DMRS端口关联。MSB的状态1可以用于指示向TRP1发送的PUSCH的PTRS与第二个DMRS端口关联。LSB中的状态0可以用于指示向TRP2发送的PUSCH的PT-RS与第一个DMRS端口关联。LSB的状态1可以用于指示向TRP2发送的PUSCH的PT-RS与第二个DMRS端口关联。
当maxrank大于2(即最大传输层数大于2)时,根据TPMI和传输层数确定实际需要1个或2个PTRS端口。DCI格式0-1或DCI格式0-2使用4比特用于指示PTRS端口与DMRS端口之间的关联关系。
在一些实施例中,根据TPMI和传输层数确定实际的PTRS端口数为1时,可以根据表2确定该PTRS端口关联的DMRS端口。
表2
状态值 | DMRS端口 |
0 | 第1个DMRS端口 |
1 | 第2个DMRS端口 |
2 | 第3个DMRS端口 |
3 | 第4个DMRS端口 |
在另一些实施例中,根据TPMI和传输层数确定实际的PTRS端口数为2时,可以根据表3确定每个PTRS端口关联的DMRS端口。其中,MSB和LSB分别与不同的TRP关联,再通过MSB和LSB的状态确定与PTRS关联的DMRS端口。
表3
实际应用中,终端设备通常被配置一个最大传输层数(即一个maxRank),终端设备可以根据该maxRank确定与PUSCH传输参数相关的指示域的比特数以及具体的指示信息,例如,终端设备可 以根据maxRank确定PTRS-DMRS关联指示(PTRS-DMRS association)域的比特数以及具体的关联关系表格。
目前的通信***中并不支持为多个panel配置不同的最大传输层数。然而,多TRP/panel/beam同时传输的场景中,不同的panel可能具有不同的最大传输层数。在引入了多TRP/panel/beam同时传输的方案后,如何根据不同的最大传输层数确定相关指示域的比特数,目前并没有明确的方法。另外,多TRP/panel/beam同时传输的方案可以和单TRP/panel/beam传输方案做切换,并且多TRP/panel/beam同时传输的方案,与单TRP/panel/beam传输方案所支持的最大传输层数也有所不同,因此不同方案对应的DCI的比特数不同,这会影响终端设备的盲检测。
基于此,在本申请一实施例中,提供一种信息处理方法,参考图2所示,信息处理方法可以包括以下步骤:
步骤210、终端设备根据一个或多个空间参数关联的最大传输层数,确定第一信息域的有效比特数。
应理解,空间参数可以表征终端设备传输上下行信道的空间关系,示例性的,空间关系可以包括终端设备传输上下行信道的panel、beam、或者TRP。
可选地,空间参数可以包括以下中的一项或多项:参考信号集合信息,传输配置指示(Transmission Configuration Indicator,TCI)状态信息,panel信息,TRP信息,控制资源集CORESET组信息(coresetPoolIndex),beam信息。
可选地,参考信号集合可以包括SRS资源集。SRS资源集可以与panel/beam/TCI state关联。实际应用中,终端设备可以采用与传输SRS资源集相同的panel/beam/TCI state传输上行信道。
TCI状态信息可以用于上下行的波束管理。其中,一个TCI状态可以包括准共址(Quasi Co-Location,QCL)类型配置和QCL参考信号配置,QCL类型配置可以是QCL类型A(typeA),QCL typeB,QCL typeC或QCL typeD中的一个,参考信号配置可以是小区标识(ID),带宽部分(Bandwidth Part,BWP)ID以及参考信号的标识(例如CSI-RS资源ID或SSB索引)。其中,不同QCL类型的定义如下:QCL TypeA用于配置以下内容{多普勒频移(Doppler shift),多普勒扩展(Doppler spread),平均时延(average delay),时延扩展(delay spread)},QCL typeB用于配置{Doppler shift,Doppler spread},QCL typeC用于配置{Doppler shift,average delay},QCL typeD用于配置{空间Rx参数(Spatial Rx parameter)}。
如果网络设备通过TCI状态为目标上行信道的QCL参考信号配置为SSB 1资源,且QCL类型配置为typeA,typeB或typeC,则终端设备可以假设上述目标上行信号与SSB 1的资源的大尺度参数是相同的或类似的,该大尺度参数通过QCL类型配置来确定。
应理解,如果两个上行信道的传输TRP或传输panel或发送波束不同,通常会配置不同的TCI状态。
本申请实施例中,panel信息可以包括panel ID,或者panel的索引值等,本申请实施例对此不做限制。
本申请实施例中,coresetPoolIndex可以与TRP关联。网络设备可以为每个CORESET配置一个用以指示是否为相同TRP的coresetPoolIndex。该值的取值范围为0和1。对于配置了相同的coresetPoolIndex的CORESET,终端设备可以认为关联相同的TRP。
另外,beam信息可以包括beam ID,或者beam的索引值等,本申请实施例对此不做限制。
同样地,TRP信息可以包括TRP ID,或者TPR的索引值等,本申请实施例对此不做限制。
本申请实施例中,终端设备可以配置有多个不同的空间参数,也就是说,终端设备可以通过多种不同的空间关系进行上行信道的传输。
可选地,参考图2所示,在终端设备传输上行信道之前,还可以执行以下步骤:
步骤200、网络设备向终端设备发送第一信息,第一信息通过第一信息域携带。
应理解,网络设备可以通过第一信息来指示终端设备传输上行信道的传输参数。
可选地,第一信息可以包括PTRS-DMRS关联信息,TPMI信息,或SRI信息。也就是说,终端设备可以根据第一信息确定传输上行信道时使用的PTRS-DMRS关联信息,预编码矩阵,或者SRS资源等信息。
本申请实施例中,第一信息可以通过第一信息域携带。可以理解的是,第一信息域可以用于指示多个TRP/panel/beam同时传输时的传输参数。其中,第一信息域可以包括以下中的一项或多项:PTRS-DMRS关联指示域、TPMI域、SRI域。
另外,本申请实施例中,终端设备配置的多个空间参数中每个空间参数均关联一个最大传输层 数。多个空间参数中不同的空间参数关联的最大传输层数可以相同也可以不同,本申请实施例对此不做限制。
可选地,多个空间参数分别关联的最大传输层数可以是根据终端设备支持的能力确定的,也可以是根据网络设备发送的配置信息确定的,本申请实施例对此不做限制。
其中,第一信息域的取值与第一信息域的有效比特数有关。终端设备接收到第一信息后,需要先确定第一信息域的有效比特数。
本申请实施例中,终端设备可以根据多个空间参数中至少一个空间参数(也就是一个或多个空间参数)来确定第一信息域中的有效比特数。
应理解,在确定了第一信息域的有效比特数之后,终端设备可以确定第一信息域的取值范围,这样,终端设备可以根据第一信息域的实际取值来确定第一信息域实际承载的第一信息。
综上所述,本申请实施例提供的信息处理方法,终端设备配置的多个空间参数可以分别关联一个最大传输层数,终端设备可以根据一个或者多个来确定第一信息域的有效比特数。这样,终端设备可以根据第一信息域的有效比特数来确定第一信息域承载的信息。
需要说明的是,本申请实施例提供的信息处理方法可以应用于多个TRP/panel/beam同时传输上行信道的场景中。
可选地,多个TRP/panel/beam同时传输的方案可以包括空间复用传输(Spatial Division Multiplexing,SDM)传输方案和单频网络(Single Frequency Network,SFN)传输方案等。
其中,SDM上行传输中,一个PUSCH的不同传输层集合通过终端设备的不同panel/beam发送给同一个TRP,或者发送给不同的TRP,其中,PUSCH的不同传输层集合的上行资源都相同。示例性的,参考图3所示的一种SDM上行传输示意图,终端设备可以通过panel1的传输层0向TRP 1发送PUSCH 1,通过panel2的传输层1向TRP 2发送PUSCH 2,其中,PUSCH 1与第一TCI状态关联,PUSCH 2与第二TCI状态关联。PUSCH 1和PUSCH 2使用相同的时频资源。
另外,SFN上行传输中,一个PUSCH的重复传输通过不同的panel/beam发送到同一个TRP,或者不同的TRP。其中,PUSCH重复传输时使用的频域资源相同,时域资源相同,DMRS端口也相同。示例性的,参考图4所示的一种SFN上行传输示意图,终端设备可以通过panel1的传输层0向TRP 1发送PUSCH,通过panel2的传输层1向TRP 2发送PUSCH重复传输。其中,PUSCH和PUSCH重复传输的时频资源相同,DMRS端口也相同。
本申请实施例中,终端设备根据一个或多个空间参数关联的最大传输层数,确定第一信息域的有效比特数的方式包括多种,以下详细介绍其中的两种。
在本申请一实施例中,步骤210中终端设备根据一个或多个空间参数关联的最大传输层数,确定第一信息域的有效比特数,可以通过以下方式实现:
步骤2101、终端设备根据多个空间参数分别关联的最大传输层数,确定第一信息域的有效比特数。
应理解,本申请实施例中,终端设备可以根据配置的多个空间参数中的每个空间参数关联的最大传输层数,确定第一信息域的有效比特数。
其中,每个空间参数关联的最大传输层数可以相同也可以不同,本申请实施例对此不做限制。
在第一种实现方式中,若多个空间参数的数量为N,每个空间参数关联的最大传输层数的数量未被限制,则第一信息域的有效比特数可以通过以下方式确定:
第一信息域的有效比特数M可以根据以下公式(1)确定:
示例性的,在N=2,即终端设备配置有2个空间参数的情况下,若2个空间参数关联的最大传输层均为1(也就是x
1=x
2=1),则M=0。若2个空间参数关联的最大传输层数有一个为2,其余一个为1(例如x
1=1,x
2=2),则M=1。若2个空间参数关联的最大传输层数均为2(也就是x
1=x
2=2),则M=2。以此类推,这里不再一一赘述。
示例性的,在N=3,即终端设备配置有3个空间参数的情况下,若3个空间参数关联的最大传输层均为1(也就是x
1=x
2=x
3=1),则M=0。若3个空间参数关联的最大传输层数有一个为2,其余两个为1(例如x
1=x
2=1,x
3=2),则M=1。若3个空间参数关联的最大传输层数有两个为2,其 余一个为1(例如x
1=x
2=2,x
3=1),则M=2。若3个空间参数关联的最大传输层数均为2(也就是x
1=x
2=x
3=2),则M=3。以此类推,这里不再一一赘述。
示例性的,在N=4,即终端设备配置有4个空间参数的情况下,若4个空间参数关联的最大传输层均为1(也就是x
1=x
2=x
3=x
4=1),则M=0。若4个空间参数关联的最大传输层数有一个为2,其余一个为1(例如x
1=x
2=x
3=1,x
4=2),则M=1。若4个空间参数关联的最大传输层数有两个为2,其余两个为1(例如x
1=x
2=1,x
3=x
4=2),则M=2。若4个空间参数关联的最大传输层数有三个为2,其余一个为1(例如x
1=x
2=x
3=2,x
4=1),则M=3。若4个空间参数关联的最大传输层数均为2(也就是x
1=x
2=x
3=x
4=2),则M=4。以此类推,这里不再一一赘述。
需要说明的是,第一信息域的总比特数大于或等于第一信息域的有效比特数。在第一信息域的总比特数大于第一信息域的有效比特数的情况下,第一信息域的有效比特可以位于第一信息域的高位比特,也可以位于第一信息域的低位比特,本申请实施例对此不做限制。例如,第一信息域的总比特数为3比特,有效比特数为2比特,其中,第一信息域的3比特中,前两个比特为有效比特,或者后两个比特为有效比特。
应理解,第一信息域的M个有效比特中不同的部分可以与不同的空间参数对应。其中,第一信息域中与某个空间参数对应的部分,可以用于指示与该空间参数关联的传输参数(例如DMRS端口、预编码矩阵等)。
示例性的,第一信息域为PTRS-DMRS关联指示域时,第一信息域的M个有效比特中与第i个空间参数对应的第i个部分,可以用于指示该第i个空间参数关联的PTRS端口和DMRS端口的关联关系。其中,第一信息域中第i个部分的不同取值对应不同的PTRS端口和DMRS端口的关联关系,当第一信息域中第i个部分的有效比特数为1,若第一信息域中第i个部分的取值为0,则指示与第i个空间参数关联时,与PTRS端口关联的DMRS端口为第一DMRS端口,若第一信息域中第i个部分的取值为1,则指示与第i个空间参数关联时,与PTRS端口关联的DMRS端口为第二DMRS端口。
应理解,第一信息域可以包括多个子信息域,每个子信息域可以对应一个空间参数。每个子信息域可以用于指示与其对应的空间参数关联的传输参数(例如空间参数关联的PTRS端口所关联的DMRS端口、预编码矩阵等)。
在第二种实现方式中,若多个空间参数的数量为N,且每个空间参数关联的最大传输层数最多为2,则第一信息域的有效比特数可以通过以下方式确定:
在N个空间参数分别关联的最大传输层数均为1的情况下,第一信息域的有效比特数为0比特;
在N个空间参数分别关联的最大传输层数中k个最大传输层数为2,N-k个最大传输层数为1的情况下,第一信息域的有效比特数为k比特,k为大于等于1且小于等于N的整数。
可选地,在一些实施例中,第一信息域的k个有效比特中,每个有效比特与N个空间参数中的一个指定空间参数对应,指定空间参数关联的最大传输层数为2。
可以理解的是,关联的最大传输层数为2的空间参数可以与k个有效比特中的1个比特对应,每个有效比特可以用于指示与该有效比特对应的空间参数关联的传输参数(例如与该空间参数关联的PTRS端口所关联的DMRS端口、预编码矩阵等)。
可选地,在另一些实施例中,第一信息域包括N个子信息域,其中,N个子信息域分别与N个空间参数对应,
N个空间参数中,关联的最大传输层数为2的空间参数所对应的子信息域的有效比特数为1比特,关联的最大传输层数为1的空间参数所对应的子信息域的有效比特数为0比特。
可以理解的是,第一信息域可以包括多个子信息域,每个子信息域可以对应一个空间参数。每个子信息域可以用于指示与其对应的空间参数关联的传输参数(例如DMRS端口、预编码矩阵等)。
在第三种实现方式中,若多个空间参数包括第一空间参数和第二空间参数,第一空间参数与第一最大传输层数关联,第二空间参考与第二最大传输层数关联,并且每个空间参数关联的最大传输 层数最多为2,则第一信息域的有效比特数可以通过以下方式确定:
在第一最大传输层数为1,且第二最大传输层数为1的情况下,第一信息域的有效比特数为0比特;
在第一最大传输层数和第二最大传输层数中的一个最大传输层数为1,另一个最大传输层数为2的情况下,第一信息域的有效比特数为1比特;
在第一最大传输层数和第二最大传输层数均为2的情况下,第一信息域的有效比特数为2比特。
可选地,在一些实施例中,在第一最大传输层数和第二最大传输层数中的一个最大传输层数为1,另一个最大传输层数为2的情况下,第一信息域可以与指定空间参数对应,指定空间参数关联的最大传输层数为2。
可以理解的是,第一信息域中的1个有效比特可以与最大传输层数为2的空间参数对应,该有效比特可以指示最大传输层数为2的空间参数关联的传输参数。
以第一信息域为PTRS-DMRS关联域进行说明,表4示出了PTRS-DMRS关联域的有效比特数为1比特时,该比特的具体指示方式。
表4
从表4中可以看出,当PTRS-DMRS关联域的取值为0时,最大传输层数为2的空间参数关联的的PTRS端口关联的DMRS端口为第一个被调度的DMRS端口。当PTRS-DMRS关联域的取值为1时,最大传输层数为2的空间参数关联的PTRS端口关联的DMRS端口为第二个被调度的DMRS端口。
另外,在第一最大传输层数和第二最大传输层数均为2的情况下,第一信息域的2个有效比特分别与第一空间参数和第二空间参数对应。
可以理解的是,第一信息域的2个有效比特中高位比特对应第一空间参数和第二空间参数中的一个空间参数,2个有效比特中的低位比特对应另一个空间参数,例如,2个有效比特中的高位比特对应索引较小的空间参数,2个有效比特中的低位比特对应索引较大的空间参数。或者,2个有效比特中的高位比特对应索引较大的空间参数,2个有效比特中的低位比特对应索引较小的空间参数。
以第一信息域为PTRS-DMRS关联域进行说明,表5示出了PTRS-DMRS关联域的有效比特数为2比特,且PTRS-DMRS关联域的高位比特与第一空间参数对应,低位比特与第二空间参数对应时,不同比特的具体指示方式。
表5
从表5可以看出,当PTRS-DMRS关联域中高位比特的取值为0时,第一空间参数关联的PTRS端口关联的DMRS端口为第一个被调度的DMRS端口。当PTRS-DMRS关联域中高位比特的取值为1时,第一空间参数关联的PTRS端口关联的DMRS端口为第二个被调度的DMRS端口。当PTRS-DMRS关联域中低位比特的取值为0时,第二空间参数关联的PTRS端口关联的DMRS端口为第一个被调度的DMRS端口。当PTRS-DMRS关联域中低位比特的取值为1时,第二空间参数关联的PTRS端口关联的DMRS端口为第二个被调度的DMRS端口。
可选地,多个空间参数中不同空间参数对应的PTRS端口不同。例如,多个空间参数包括第一空间参数和第二空间参数,第一空间参数对应PTRS端口0,第二空间参数对应PTRS端口1。对于表5来说,高位比特对应第一空间参数,也就是对应PTRS端口0,低位比特对应第二空间参数,也就是对应PTRS端口1。
可选地,多个空间参数中的不同空间参数对应的PTRS端口相同。例如,多个空间参数包括第 一空间参数和第二空间参数,第一空间参数和第二空间参数都对应PTRS端口0。进一步的,多个空间参数中的不同空间参数对应的PTRS端口相同时,该PTRS端口对应的DMRS端口也相同。或者,多个空间参数中的不同空间参数对应的PTRS端口相同时,该PTRS段卡欧也可以对应不同的DMRS端口。
可选地,在另一些实施例中,第一信息域可以包括第一子信息域和第二子信息域,第一子信息域与第一空间参数对应,第二子信息域与第二空间参数对应。
可以理解的是,第一子信息域可以用于指示第一空间参数关联的传输参数(例如DMRS端口、预编码矩阵等)。第二子信息域可以用于指示第二空间参数关联的传输参数(例如空间参数关联的PTRS端口关联的DMRS端口、预编码矩阵等)。
其中,在第一最大传输层数和第二最大传输层数中的一个最大传输层数为1,另一个最大传输层数为2的情况下,第一信息域中的第一目标子信息域的有效比特数为0比特,第二目标子信息域的有效比特数为1比特;其中,第一目标子信息域是最大传输层数为1的空间参数对应的子信息域,第二目标子信息域是最大传输层数为2的空间参数对应的子信息域。
可以理解的是,在第一最大传输层数和第二最大传输层数中的一个最大传输层数为1,另一个最大传输层数为2的情况下,第一信息域中关联的最大传输层数取值为2的空间参数对应的子信息域的有效比特数为1比特,关联的最大传输层数据取值为1的空间参数对应的子信息域的有效比特数为0比特。
也就是说,当第一最大传输层数为1,第二最大传输层数为2时,第一信息域中的第一子信息域的有效比特数为0比特,第二子信息域的有效比特数为1比特。当第一最大传输层数为2,第二最大传输层数为1,第一信息域中的第一子信息域的有效比特数为1比特,第二子信息域的有效比特数为0比特。
另外,在第一最大传输层数和第二最大传输层数均为2的情况下,第一子信息域和第二子信息域的有效比特数均为1比特。
示例性的,以第一信息域为PTRS-DMRS关联域进行说明,表6示出了PTRS-DMRS关联域中具有有效比特数的每个子信息域的指示方式。
表6
从表6可以看出,具有有效比特数的子信息域的取值为0时,该子信息域对应的空间参数关联的PTRS端口关联的DMRS端口为第一个被调度的DMRS端口。具有有效比特数据的子信息域的取值为1时,该子信息域对应的空间参数关联的DMRS端口为第二个被调度的DMRS端口。
在本申请另一实施例中,步骤210中终端设备根据一个或多个空间参数关联的最大传输层数,确定第一信息域的有效比特数,还可以通过以下方式实现:
步骤2102、终端设备根据第三最大传输层数,确定第一信息域的有效比特数;第三最大传输层数与多个空间参数关联。
应理解,多个空间参数关联的最大传输层数均为第三传输层数。也就是说,多个空间参数关联的最大传输层数相同,均为第三传输层数。
在第一种实现方式中,若多个空间参数的数量为N,第三最大传输层数为大于或等于1的任一整数,则第一信息域的有效比特数可以通过以下方式确定:
第一信息域的有效比特数M根据以下公式(2)确定:
示例性的,在N=3,即终端设备配置有3个空间参数的情况下,若y=1,则第一信息域的有效比特数为0比特;若y=2,则第一信息域的有效比特数为3比特,且每个空间参数对应一个比特;若y=3,则第一信息域的有效比特数为6比特,且每个空间参数对应两个比特。以此类推,这里不再一一赘述。
应理解,第一信息域的M个有效比特中不同的部分可以与不同的空间参数对应。其中,与某个空间参数对应的部分,可以用于指示与该空间参数关联的传输参数(例如该空间参数关联的PTRS端口所关联的DMRS端口、预编码矩阵等)。
第一信息域为PTRS-DMRS关联指示域时,第一信息域的M个有效比特中与第i个空间参数对应的第i个部分,可以用于指示该第i个空间参数关联的PTRS端口和DMRS端口的关联关系。其中,第一信息域中第i个部分的不同取值对应不同的PTRS端口和DMRS端口的关联关系,当第一信息域中第i个部分的有效比特数为1,若第一信息域中第i个部分的取值为0,则指示与第i个空间参数时,与PTRS端口关联的DMRS端口为第一DMRS端口,若第一信息域中第i个部分的取值为1,则指示与第i个空间参数关联时,与PTRS端口关联的DMRS端口为第二DMRS端口。
应理解,第一信息域可以包括多个子信息域,每个子信息域可以对应一个空间参数。每个子信息域可以用于指示与其对应的空间参数关联的传输参数(例如该空间参数关联的PTRS端口所关联的DMRS端口、预编码矩阵等)。
在第二种实现方式中,若多个空间参数的数量为N,且每个空间参数关联的最大传输层数最多为2,则第一信息域的有效比特数可以通过以下方式确定:
在第三最大传输层数为1的情况下,第一信息域的有效比特数为0比特;在第三最大传输层数为2的情况下,第一信息域的有效比特数为N比特。
在一些实施例中,在第三最大传输层数为2的情况下,第一信息域中N个有效比特分别与N个空间参数对应。第一信息域中N个有效比特中的每个有效比特与一个空间参数对应。
在另一些实施例中,第一信息域包括N个子信息域,其中,N个子信息域分别与N个空间参数对应,在第三最大传输层数为2的情况下,N个子信息域的有效比特数均为1比特。
在第三种实现方式中,若多个空间参数包括第一空间参数和第二空间参数,第一空间参数与第一最大传输层数关联,第二空间参考与第二最大传输层数关联,并且第三最大传输层数最多为2,则第一信息域的有效比特数可以通过以下方式确定:
在第三最大传输层数为1的情况下,第一信息域的有效比特数为0比特;
在第三最大传输层数为2的情况下,第一信息域的有效比特数为2比特。
在一种可能的实现方式中,在第三最大传输层数为2的情况下,第一信息域的2个比特分别与第一空间参数和所述第二空间参数对应。
在另一种可能的实现方式中,第一信息域包括第一子信息域和第二子信息域,第一子信息域与第一空间参数对应,第二子信息域与所述第二空间参数对应;其中,在第三最大传输层数为2的情况下,第一子信息域和第二子信息域的有效比特数均为1比特。
在本申请一实施例中,参考图5所示,本申请实施例提供的信息处理方法还可以包括以下步骤:
步骤220、终端设备向网络设备发送第二信息,对应的,网络设备接收终端设备发送的第二信息;第二信息用于指示终端设备支持配置的最大传输层数的个数。
应理解,最大传输层数有多种配置方式,其中,最大传输层数的配置方式与终端设备能够配置的最大传输层数的个数有关。不同的配置方式中,终端设备配置的最大传输层数的个数可能不同。例如,终端设备可以支持配置1个最大传输层数、2个最大传输层数、N个最大传输层数等。
其中,最大传输层数的不同配置方式对应的第一信息域的设计是不同的。基于此,终端设备可以将其支持的配置上报给网络设备。
可选地,第二信息可以通过专用信令发送,也可以通过终端设备的能力信息(例如UECapabilityInformation)发送,本申请实施对此不做限制。
在一些实施例中,第二信息可以用于指示以下中的一项或多项:
终端设备支持配置N+1个最大传输层数,N+1个最大传输层数中的N个最大传输层数(例如N+1个最大传输层数中的前N个最大传输层数,或者后N个最大传输层数)用于第一传输模式,N+1个最大传输层数中其余1个最大传输层数(例如N+1个最大传输层数中的第N+1个最大传输层数,或者第1个最大传输层数)用于第二传输模式;
终端设备支持配置N个最大传输层数,N个最大传输层数用于第一传输模式,N个最大传输层 数中指定最大传输层数用于所述第二传输模式,指定最大传输层数关联的空间参数与所述第二传输模式关联的空间参数相同;
终端设备支持配置2个最大传输层数,2个最大传输层数中的一个用于第一传输模式,另一个用于第二传输模式;
终端设备支持配置1个最大传输层数,1个最大传输层用于第一传输模式和第二传输模式;
其中,第一传输模式包括多个TRP/panel/beam同时传输,第二传输模式包括单TRP/panel/beam传输。
需要说明的是,终端设备可以同时支持多个TRP/panel/beam同时传输的第一传输模式,以及单TRP/panel/beam传输的第二传输模式。其中,终端设备的最大传输层的配置方式可以与第一传输模式、以及第二传输模式有关。
需要说明的是,终端设备支持配置的最大传输层数的个数属于终端设备的能力。本申请实施例中,终端设备可以具有以下四种能力。
能力A:终端设备支持配置N+1个最大传输层,N+1个最大传输层数中的N个最大传输层数用于多个TRP/panel/beam同时传输,N+1个最大传输层数中的其余1个最大传输层数用于单TRP/panel/beam传输。
可以理解的是,终端设备配置有N个空间参数,终端设备可以支持配置N+1个最大传输层数。其中,终端设备可以为第一传输模式中N个空间参数中的每个空间参数配置一个最大传输层数。为第二传输模式中的单TRP/panel/beam传输配置一个最大传输层数。
其中,第一传输模式中,每个空间参数配置的最大传输层数可以相同,也可以不同,本申请实施例对此不做限制。另外,第一传输模式配置的N个最大传输层数,与第二传输模式配置的1个最大传输层数可以相同,也可以不同,本申请实施例对此不做限制。
能力B、终端设备支持配置N个最大传输层数,N个最大传输层数用于第一传输模式,N个最大传输层数中指定最大传输层数用于第二传输模式,指定最大传输层数关联的空间参数与第二传输模式关联的空间参数相同。
可以理解的是,终端设备可以支持配置N个最大传输层数。N个最大传输层数可以与终端设备配置的N个空间参数一一对应。
在第一传输模式中,多个TRP/panel/beam传输时,不同的空间参数关联的最大传输层数可以相同,也可以不同,本申请实施例对此不做限制。
在第二传输模式中,单TRP/panel/beam传输关联的最大传输层数可以是N个最大传输层数中的其中一个指定最大传输层数。该指定最大传输层数关联的空间参数,与单TRP/panel/beam传输关联的空间参数相同。
能力C、终端设备支持配置2个最大传输层数,2个最大传输层数中的一个用于第一传输模式,另一个用于第二传输模式。
可以理解的是,在第一传输模式中,N个空间参数关联的最大传输层数均相同。示例性的,参考上述实施例的描述,N个空间参数可以与第三最大传输层数关联。
需要说明的是,在该配置方式中,用于第一传输模式的最大传输层数和用于第二传输模式的最大传输层数可以相同,也可以不同,本申请实施对此不做限制。
能力D、终端设备支持配置1个最大传输层数,该最大传输层用于第一传输模式和第二传输模式。
可以理解的是,终端设备可以只配置一个最大传输层数,该最大传输层数可以用于第一传输模式和/或第二传输模式。
可选地,在终端设备支持配置1个最大传输层数的情况下,多个空间参数分别关联的最大传输层数为第一数量与第二数量的最小值。
也就是说,在终端设备只支持配置1个最大传输层数的情况下,在第一传输模式中,终端设备配置的多个空间参数关联的最大传输层数可以是min{第一数量,第二数量}。
其中,第一数量为第一传输模式中每个TRP/panel/beam支持传输的最大传输层数,即多TRP/panel/beam同时传输上行信道时,每个TRP/panel/beam能够传输的上行信道的最大层数,例如第一数量为2。另外,第二数量为第二传输模式中单TRP/panel/beam支持传输的最大传输层数。
本申请实施例中,终端设备可以将上述四种能力中的一种或多种能力,通过第二信息上报给网络设备,以便于网络设备基于上报的能力对终端设备进行上行调度。由于最大传输层数的配置方法对网络设备侧发送的DCI的设计及比特数影响很大,且对终端设备的盲检测影响也很大,因此终端 设备上报支持的最大传输层数的配置,具有较高的灵活度。
可选地,参考图5所示,在步骤220的基础上,本申请实施例提供的信息处理方法还包括以下步骤:
步骤230、终端设备向网络设备发送第三信息,对应的,网络设备接收终端设备发送的第三信息,第三信息用于指示终端设备支持配置的最大传输层数中各最大传输层数的数量。
可以理解的是,终端设备除了可以向网络设备上报支持配置的最大传输层数的个数之外,还可以向网络设备上报支持配置的每个最大传输层数的具体数量。
示例性的,终端设备支持配置N+1个最大传输层数时,可以通过第三信息向网络设备上报N+1个最大传输层数中每个最大传输层数的具体数量。终端设备支持配置N个最大传输层数时,可以通过第三信息向网络设备上报这N个最大传输层数中每个传输层数的具体数量。
需要说明的是,第三信息可以通过专用信令发送,也可以通过终端设备的能力信息发送。另外,第三信息与上述第二信息可以为同一信息,也可以为不同的信息。本申请实施例对此不做限制。
示例性的,终端设备可以通过UECapabilityInformation向网络设备上报其支持配置的最大传输层数的个数,以及各最大传输层数的具体数量。
在一些实施例中,上述多个空间参数分别关联的最大传输层数,和/或,第三最大传输层数根据以下任意一项确定:
终端设备支持配置的各最大传输层数的数量;
网络设备发送的配置信息;
预定义规则。
在一种可能的实现方式中,多个空间参数分别关联的最大传输层数,和/或,第三最大传输层数可以是网络设备配置的,也可以是预定义规则确定的。预定义规则可以通过在设备(例如,包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现,本申请对于其具体的实现方式不做限定。在一些实施例中,预定义规则也可以是预定义的值,示例性的,预定义的值可以是2、4等,本申请实施例对此不做限制。
在另一种可能的实现方式中,终端设备可以根据其支持配置的最大传输层数的个数,以及每个最大传输层数的具体数量确定上述实施例中多个空间参数分别关联的最大传输层数,和/或,第三最大传输层数。
示例性的,以终端设备配置有N个空间参数为例进行说明。在终端设备支持配置N+1个最大传输层数的情况下,终端设备可以根据N+1个最大传输层数中用于第一传输模式的N个最大传输层数,确定上述N个空间参数分别关联的最大传输层数。其中,不同空间参数关联的最大传输层数可以相同也可以不同。若N个空间参数关联的最大传输层数相同,则可以得到上述实施例中的第三最大传输层数。
在终端设备支持配置N个最大传输层数的情况下,终端设备可以根据该N个最大传输层数确定上述N个空间参数分别关联的最大传输层数。其中,不同的空间参数关联的最大传输层数可以相同,也可以不同。若N个空间参数关联的最大传输层数相同,则可以得到上述实施例中的第三最大传输层数。
在终端设备支持配置2个最大传输层数的情况下,终端设备可以根据2个最大传输层数中用于第一传输模式的最大传输层数,确定上述N个空间参数关联的最大传输层数,得到第三最大传输层数。
在终端设备只配置1个最大传输层数的情况下,第三最大传输层数=min{第一数量,第二数量}。其中,第二数量是用于单TRP/panel/beam传输的最大传输层数,也可以是该实现方式中终端设备仅配置的1个最大传输层数。
也就是说,多个空间参数分别关联的最大传输层数可以与第二数量均不同。或者,多个空间参数分别关联的最大传输层数中的指定最大传输层数,与第二数量相同;指定最大传输层数关联的空间参数与第二传输模式关联的空间参数相同。
另外,第三最大传输层数与第二数量不同。或者,第三最大传输层数为第一数量与第二数量的最小值。
在又一种可能的实现方式中,终端设备通过第二信息和/或第三信息向网络设备上报其支持配置的最大传输层数的个数,以及各最大传输层数的数量的情况下,网络设备可以根据终端设备上报的上述能力,来为终端设备配置实际应用中多个空间参数分别关联的最大传输层数,和/或,第三最大传输层数。终端设备通过第二信息和/或第三信息向网络设备上报其支持配置的最大传输层数的个数, 以及各最大传输层数的数量的情况下,终端设备和网络设备也可以根据预定义规则确定实际应用中多个空间参数分别关联的最大传输层数,和/或,第三最大传输层数。
在一些实施例中,终端设备可以在第一传输模式和第二传输模式之间相互切换。可选地,终端设备可以根据网络设备的指示来实现第一传输模式和第二传输模式之间的切换。应理解,在第一传输模式下,终端设备可以根据上述实施例提供的方法确定第一信息域的有效比特数。
在本申请一实施例中,步骤210中,终端设备根据一个或多个空间参数关联的最大传输层数,确定第一信息域的有效比特数,还可以基于以下方式来实现:
在接收到第四信息的情况下,终端设备根据一个或多个空间参数关联的最大传输层数,确定第一信息域的有效比特数;
第四信息用于指示通过多个TRP/panel/beam同时传输。
需要说明的是,第四信息可以用于指示通过多个TRP/panel/beam同时传输,也可以用于指示通过单TRP/panel/beam传输。
其中,第四信息用于指示通过多个TRP/panel/beam同时传输,可以理解为,第四信息可以指示终端设备采用第一传输模式进行上行信道传输。或者指示终端设备同时应用多种空间参数发送上行信道,或者指示终端设备采用SDM/SFN方案发送上行信道。
第四信息用于指示通过单TRP/panel/beam传输,可以理解为,第四信息可以指示终端设备采用第二传输模式进行上行信道传输。
示例性的,若第四信息取值为第一值(例如“10”或“11”),则指示终端设备通过多个TRP/panel/beam同时传输上行信道,若第四信息取值为第二值(例如“01”或“00”),则指示终端设备通过单TRP/panel/beam传输上行信道。
示例性的,第四信息可以是第一SRS资源集指示信息,第一SRS资源集指示信息用于指示SRS资源集。当第一SRS资源集指示信息用于指示多个SRS资源时,可以隐式地指示终端设备通过多个TRP/panel/beam同时传输上行信道。当第一SRS资源集指示信息用于指示一个SRS资源时,可以指示终端设备通过单TRP/panel/beam传输。或者,当第一SRS资源集指示信息取值为第一值(例如“10”或“11”),则指示终端设备通过多个TRP/panel/beam同时传输上行信道,当第一SRS资源集指示信息取值为第二值(例如“01”或“00”),则指示终端设备通过单TRP/panel/beam传输上行信道。
本申请实施例中,当第四信息用于指示通过多个TRP/panel/beam同时传输时,终端设备可以确定根据一个或多个空间参数关联的最大传输层数,确定第一信息域的有效比特数。终端设备根据一个或多个空间参数关联的最大传输层数,确定第一信息域的有效比特数的方式与上述实施例描述的方式相同,为了简洁,此处不再赘述。
在本申请一实施例中,终端设备接收第一DCI,第一DCI为调度多个TRP/panel/beam同时传输的DCI,第一DCI中包括第一信息域。也就是说,本申请实施例中的第一信息域可以通过第一DCI携带。
在一种可能的实现方式中,第一DCI的总比特数与第二DCI的总比特数相同,第二DCI为调度单个TRP/panel/beam传输的DCI。
应理解,在第一传输模式和第二传输模式之间相互切换的场景中,为了避免终端设备的盲检次数的增加,网络设备可以设置调度多个TRP/panel/beam同时传输的第一DCI的总比特数,与调度单TRP/panel/beam传输的第二DCI的总比特数相同。即对齐第一DCI和第二DCI的总比特数。
可选地,第一DCI的总比特数和第二DCI的总比特数为,第一DCI的有效比特数与第二DCI的有效比特数中的最大值。
应理解,将第一DCI的有效比特数记为第一比特数,将第二DCI的有效比特数记为第二比特数。第一DCI和第二DCI的总比特数=max{第一比特数,第二比特数}。
其中,在第一DCI的有效比特数与第二DCI的有效比特数不同的情况下,第一DCI或第二DCI中有效比特数小的DCI的总比特数,通过补零直至总比特数与有效比特数大的DCI的总比特数相同。
也就是说,网络设备可以对有效比特数较小的DCI进行补零处理,来对齐第一DCI和第二DCI的总比特数,使得第一DCI的总比特数和第二DCI的总比特数相同。示例性的,若第一DCI的有效比特数小于第二DCI的有效比特数,则在第一DCI的有效比特数之后进行补零,即从高位比特开始补零。此外,也可以从低位比特进行补零,本申请实施例对此不做限制。
由此可见,本申请实施例提供的信息处理方法,可以对齐调度多个TRP/panel/beam同时传输的第一DCI的总比特数和调度单TRP/panel/beam传输的第二DCI的总比特数,使得第一DCI的总比特数和第二DCI的总比特数相同。这样,在终端设备在第一传输模式和第二传输模式之间动态切换 时,避免终端设备因为第一DCI和第二DCI的总比特不同,导致终端设备盲检次数增加。
在另一种可能的实现方式中,第二DCI中可以包括第二信息域,第二信息域与第一信息域的功能相同;其中,第二信息域的总比特数与第一信息域的总比特数相同。
在该实现方式中,可以设置第一DCI和第二DCI中具有相同功能的第一信息域和第二信息域的总比特数相同,也就是说,对齐第一DCI和第二DCI中相同功能的信息域的总比特数。
示例性的,第二信息域可以括以下中的一项或多项:PTRS-DMRS关联域、TPMI域、SRI域。
可选地,第一信息域的总比特数和第二信息域的总比特数,为第一信息域的有效比特数和第二信息域的有效比特数中的最大值。
这里,将第一信息域的有效比特数记为第一比特数,将第二信息域的有效比特数记为第二比特数。第一DCI和第二DCI中第一信息域与第二信息域的总比特数=max{第一比特数,第二比特数}。
其中,在第二信息域的有效比特数与第一信息域的有效比特数不同的情况下,第一信息域或第二信息域中有效比特数小的信息域,通过补零直至总比特数与有效比特数大的信息域的总比特数相同。
也就是说,网络设备可以对有效比特数较小的DCI进行补零处理,来对齐第一DCI和第二DCI的总比特数,使得第一DCI的总比特数和第二DCI的总比特数相同。示例性的,若第一DCI的有效比特数小于第二DCI的有效比特数,则在第一DCI的有效比特数之后进行补零,即从高位比特开始补零。此外,也可以从低位比特进行补零,本申请实施例对此不做限制。
可选地,通过对第一信息域或第二信息域进行补零操作,使得第一信息域和第二信息域的总比特数相同之后,若承载第一信息域的第一DCI,和承载第二信息域的第二DCI总比特数不同,可以继续对第一DCI和第二DCI中比特数小的进行补零,使得第一DCI和第二DCI的总比特数相同。
由此可见,本申请实施例提供的信息处理方法,可以对齐具有相同功能的信息域的总比特数,使得具有相同功能的信息域的总比特数相同。同时,还可以对齐第一DCI和第二DCI的总比特数,这样,在终端设备在第一传输模式和第二传输模式之间动态切换时,避免终端设备因为第一DCI和第二DCI的总比特不同,导致终端设备盲检次数增加。
在又一种可能的实现方式中,第二DCI包括第二信息域,第二信息域与第一信息域的功能相同;其中,第一信息域包括N个子信息域,N个子信息域分别与多个空间参数对应;第一信息中指定子信息域的总比特数与第二信息域的总比特数相同;指定子信息域对应的空间参数与第二信息域关联的空间参数相同。
在该实现方式中,网络设备可以设置第一DCI和第二DCI中同一空间参数关联的相同功能的信息域的比特总数相同,也就是说,将同一空间参数关联的相同功能的信息域的比特数进行对齐。
应理解,第一DCI可以为调度多个TRP/panel/beam同时传输的DCI,第一DCI中的第一信息域可以与多个不同的空间参数对应。第二DCI为调度单个TRP/panel/beam传输的DCI,第二DCI中的第二信息域可以与单TRP/panel/beam传输的空间参数对应。
可选地,目标子信息域的总比特数与所述第二信息域的总比特数为,目标子信息域的有效比特数与第二信息域的有效比特数的最大值。
其中,在目标子信息域的有效比特数与第二信息域的有效比特数不同的情况下,目标子信息域或第二信息域中有效比特数小的信息域,通过补零直至总比特数与有效比特数大的信息域的总比特数相同。
