Description

本公开涉及通信技术领域,尤其涉及一种信息指示方法、装置、设备及存储介质。
背景技术
在通信系统中,通过引入相关联合传输,使得MU-MIMO(Multi User-Multi Input Multi Output,多用户多进多出)系统可以支持更多UE(User equipment,用户设备)来获得较大的系统增益。其中,通过对现有的DMRS(Demodulation Reference Signal,解调参考信号)映射类型(type)进行增强得到增强后的DMRS type,增强后的DMRS type相较于现有的DMRS type能够支持更多的端口,以此使得MU-MIMO支持更多的UE。

下面参考附图对本公开实施例所提供的信息指示方法/装置/设备及存储介质进行详细描述。
图1为本公开实施例所提供的一种信息指示方法的流程示意图,应用于网络设备,如图1所示,该信息指示方法可以包括以下步骤:
步骤101、向UE指示UE数据信道的DMRS信息。
在本公开的一个实施例之中,UE可以是指向用户提供语音和/或数据连通性的设备。终端设备可以经RAN(Radio Access Network,无线接入网)与一个或多个核心网进行通信,UE可以是物联网终端,如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remoteterminal)、接入终端(access terminal)、用户装置(user terminal)或用户代理(useragent)。或者,UE也可以是无人飞行器的设备。或者,UE也可以是车载设备,比如,可以是具有无线通信功能的行车电脑,或者是外接行车电脑的无线终端。或者,UE也可以是路边设备,比如,可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
以及,在本公开的一个实施例之中,该DMRS信息可以包括以下至少一种:
DMRS映射类型;
UE数据信道对应的DMRS端口信息。
其中,在本公开的一个实施例之中,上述的DMRS映射类型可以包括第一类DMRS映射类型和/或第二类DMRS映射类型。具体的,该第一类DMRS映射类型可以是现有存在的DMRS映射类型,如可以是Rel16/17中的DMRS映射类型,例如,第一类DMRS映射类型可以包括DMRS映射类型type1和DMRS type2。第二类DMRS映射类型可以为从支持端口数这一维度对第一类DMRS映射类型增强后的映射类型(也即是,第二类DMRS映射类型支持的端口数多于第一类DMRS映射类型支持的端口数,如第二类DMRS映射类型支持的端口数是第一类DMRS映射类型支持的端口数的两倍),如可以是Rel18中的DMRS映射类型,例如,第二类DMRS映射类型包括DMRS type3和DMRS type4,其中,DMRS type3为对DMRS type1增强后的映射类型,DMRS type4为对DMRS type2增强后的映射类型。
以及,上述的DMRS端口信息可以为DMRS映射类型支持的端口中分配给UE的数据信道的DMRS端口。其中,该数据信道可以包括PUSCH(Physical Uplink Shared CHannel,物理上行分享信道)和PDSCH(Physical Downlink Shared CHannel,物理下行分享信道)。
综上所述,在本公开实施例提供的信息指示方法之中,网络设备会向UE指示UE的DMRS信息,其中,DMRS信息包括以下至少一种:DMRS映射类型、UE对应的DMRS端口信息;其中,DMRS映射类型包括第一类DMRS映射类型和/或第二类DMRS映射类型,第二类DMRS映射类型为从支持端口数这一维度对第一类DMRS映射类型增强后的映射类型;DMRS端口信息为DMRS映射类型支持的端口中分配给UE的数据信道的DMRS端口。由此可知,在本公开实施例提供的指示方法能够指示第二类DMRS映射类型(即增强后的DMRS映射类型)和第二类DMRS映射类型的DMRS端口信息,则可以支持多TRP下的相关联合传输,促进了多TRP相关联合传输的部署。
图2为本公开实施例所提供的一种信息指示方法的流程示意图,应用于网络设备,如图2所示,该信息指示方法可以包括以下步骤:
步骤201、通过RRC(Ratio Resource Control,无线资源控制)信令向UE发送指示第一类DMRS映射类型下的各DMRS type和/或第二类DMRS映射类型下的各DMRS type。
在一种可能的实现方式中,网络设备可以通过RRC(Ratio Resource Control,无线资源控制)信令向UE发送指示第一类DMRS映射类型下的各DMRS type和第二类DMRS映射类型下的各DMRS type。在另一种可能的实现方式中,网络设备可以通过不同的信令分别向UE发送指示第一类DMRS映射类型下的各DMRS type和第二类DMRS映射类型下的各DMRS type,例如可以通过一个RRC信令指示第一类DMRS映射类型下的各DMRS type,并通过另一个RRC信令指示第二类DMRS映射类型下的各DMRS type。在又一种可能的实现方式中,网络设备可以通过RRC(Ratio Resource Control,无线资源控制)信令向UE指示第二类DMRS映射类型下的各DMRS type。
其中,关于第一类DMRS映射类型下的各DMRS type和第二类DMRS映射类型下的各DMRS type的介绍可以参考上述实施例描述,本公开实施例在此不做赘述。
以及,在本公开的一个实施例之中,针对于第二类DMRS映射类型下的各DMRS type(如DMRS type3,DMRS type4)新增加了对应的指示信息,如可以利用指示信息一指示DMRS type3,利用指示信息二指示DMRS type4。同时,由于现有的第一类DMRS映射类型下的各DMRS type已经对应存在有指示信息,如指示信息三对应指示DMRS type1,指示信息四对应指示DMRS type2,因此,可以使得RRC信令中包括不同的指示信息来指示第一类DMRS映射类型下的各DMRS type或第二类DMRS映射类型下的各DMRS type。例如,当RRC信令中包括指示信息二时,则指示第二类DMRS映射类型下的DMRS type4。
此外,在本公开的一个实施例之中,该RRC信令中可以包括用于指示第一类DMRS映射类型和/
或第二类DMRS映射类型dmrs-type信令。
综上所述,在本公开实施例提供的信息指示方法之中,网络设备会向UE指示UE的DMRS信息,其中,DMRS信息包括以下至少一种:DMRS映射类型、UE对应的DMRS端口信息;其中,DMRS映射类型包括第一类DMRS映射类型和/或第二类DMRS映射类型,第二类DMRS映射类型为从支持端口数这一维度对第一类DMRS映射类型增强后的映射类型;DMRS端口信息为DMRS映射类型支持的端口中分配给UE的数据信道的DMRS端口。由此可知,在本公开实施例提供的指示方法能够指示第二类DMRS映射类型(即增强后的DMRS映射类型)和第二类DMRS映射类型的DMRS端口信息,则可以支持多TRP下的相关联合传输,促进了多TRP相关联合传输的部署。
图3为本公开实施例所提供的一种信息指示方法的流程示意图,应用于网络设备,如图3所示,该信息指示方法可以包括以下步骤:
步骤301、通过RRC信令向UE发送第一信息和第二信息。
其中,该第一信息为DMRS type对应的表示信息,用于表示DMRS type,如用于表示DMRS type1和DMRS type2,第二信息用于指示第一信息表示的DMRS type是属于未增强的DMRS type(即第一类DMRS映射类型)还是属于增强后的DMRS type(即第二类DMRS映射类型)。
在一种可能的实现方式中,可以通过RRC信令向UE发送第一信息和第二信息;当然,也可以通过其他信令向UE发送第一信息和第二信息,本公开实施例并不对此作出限定。下面以RRC为例进行说明,当然本领域内技术人员可以理解这种示例性的说明方式中,可以将RRC信令替换为任何恰当的信令。
在本公开实施例中,第一类DMRS映射类型可以包括DMRS映射类型type1和DMRS type2,第二类DMRS映射类型包括DMRS type3和DMRS type4;其中DMRS type3可以为DMRS映射类型type1的增强,而DMRS type4可以为DMRS type2的增强。这样可以通过第一信息和第二信息一起指示,即:一个信息用于指示是DMRStype1还是DMRS type2,另一个信息可以用于指示是否为增强。这样就可以通过第一信息和第二信息确定是DMRS type1、DMRS type1、DMRS type3、DMRS type4中的哪一个。
进一步地,该第二信息可以为标识符A,以指示出第一信息表示的DMRS type是属于未增强的
DMRS type(即第一类DMRS映射类型)还是属于增强后的DMRS type(即第二类DMRS映射类型)。具体的,该标识符A可以包括F比特,其中,F为正整数,当该标识符A为第一指示(如第一数值)时,则说明第一信息表示DMRS type是属于增强后的DMRS type(即第二类DMRS映射类型),当该标识符A为第二指示(如第二数值)时,则说明第一信息表示DMRS type是属于未增强的DMRS type(即第一类DMRS映射类型)。
示例的,在本公开的一个实施例之中,假设标识符A为1比特,上述第一数值可以为“1”,上述第二数值可以为“0”。
基于上述内容,在本公开的一个实施例之中,RRC信令指示第一类DMRS映射类型下的各DMRS type或第二类DMRS映射类型下的各DMRS type的方法可以为:
响应于第二信息为第一指示,则说明所述第一信息表示的DMRS type是属于增强后的DMRS type(即第二类DMRS映射类型),此时,RRC信令指示的DMRS映射类型可以为:第一信息所表示的DMRS type对应的增强后的DMRS type;
以及
响应于第二信息为第二指示,则说明所述第一信息表示的DMRS type是属于未增强的DMRS type(即第一类DMRS映射类型),此时,RRC信令指示的DMRS映射类型可以为:第一信息所表示的DMRS type。
示例的,假设RRC信令中的第一信息为DMRS type1的表示信息,此时,若第二信息被置为第一指示;则可以确定RRC信令所指示的DMRS映射类型为:现有的DMRS type1对应的增强后的DMRS type1(如可以为DMRS type3)。若第二信息被置为第二指示;则可以确定RRC信令所指示的DMRS映射类型为:现有的DMRS type1。当然,第一类DMRS映射类型可以包括DMRS映射类型type1和DMRS type2,第二类DMRS映射类型包括DMRS type3和DMRS type4,因此RRC信令可以通过多种方式指示这四种DMRS映射类型。例如:第二信息可以为两个指示标识,并结合其他指示方式(例如编码方式或是其他指示符)的方式共同指示这四种DMRS映射类型。本领域内技术人员可以理解,这四种DMRS映射类型的指示方式可以为多种,在此不再进行限定。
综上所述,在本公开实施例提供的信息指示方法之中,网络设备会向UE指示UE的DMRS信息,其中,DMRS信息包括以下至少一种:DMRS映射类型、UE对应的DMRS端口信息;其中,DMRS映射类型包括第一类DMRS映射类型和/或第二类DMRS映射类型,第二类DMRS映射类型为从支持端口数这一维度对第一类DMRS映射类型增强后的映射类型;DMRS端口信息为DMRS映射类型支持的端口中分配给UE的数据信道的DMRS端口。由此可知,在本公开实施例提供的指示方法能够指示第二类DMRS映射类型(即增强后的DMRS映射类型)和第二类DMRS映射类型的DMRS端口信息,则可以支持多TRP下的相关联合传输,促进了多TRP相关联合传输的部署。
图4为本公开实施例所提供的一种信息指示方法的流程示意图,应用于网络设备,如图4所示,该信息指示方法可以包括以下步骤:
步骤401、通过RRC信令向UE发送第一信息,通过动态信令向UE发送第二信息;
其中,该第一信息为DMRS type对应的表示信息,用于表示DMRS type,如用于表示DMRS type1 和DMRS type2,第二信息用于指示第一信息表示的DMRS type是属于未增强的DMRS type(即第一类DMRS映射类型)还是属于增强后的DMRS type(即第二类DMRS映射类型)。
其中,关于第一信息和第二信息的相关介绍可以参考上述实施例描述,本公开实施例在此不做赘述。
以及,在本公开的一个实施例之中,上述的动态信令可以为MAC CE(Medium Access Control-Control Element,媒体介入控制-控制单元)或者DCI(Downlink Control Information,下行控制信息)信令。
以及,在本公开的一个实施例之中,RRC信令和动态信令动态指示第一类DMRS映射类型下的各DMRS type或第二类DMRS映射类型下的各DMRS type的方法可以为以下的至少一种:
响应于动态信令发送的第二信息为第一指示,则RRC信令中的第一信息指示的DMRS映射类型可以为DMRS type对应的增强后的DMRS type;
以及
响应于动态信令发送的第二信息为第二指示,则RRC信令中的第一信息指示的DMRS映射类型可以为DMRS type。
上述实施例中,通过RRC信令结合动态信令一起指示DMRS映射类型。
当然,第一类DMRS映射类型可以包括DMRS映射类型type1和DMRS type2,第二类DMRS映射类型包括DMRS type3和DMRS type4,因此与前述实施例中相同的是,可以通过RRC信令和动态信令结合一起指示这四种DMRS映射类型。例如:第二信息可以为两个指示标识,并结合其他指示方式(例如编码方式或是其他指示符)的方式共同指示这四种DMRS映射类型。本领域内技术人员可以理解,这四种DMRS映射类型的指示方式可以为多种,在此不再进行限定。
综上所述,在本公开实施例提供的信息指示方法之中,网络设备会向UE指示UE的DMRS信息,其中,DMRS信息包括以下至少一种:DMRS映射类型、UE对应的DMRS端口信息;其中,DMRS映射类型包括第一类DMRS映射类型和/或第二类DMRS映射类型,第二类DMRS映射类型为从支持端口数这一维度对第一类DMRS映射类型增强后的映射类型;DMRS端口信息为DMRS映射类型支持的端口中分配给UE的数据信道的DMRS端口。由此可知,在本公开实施例提供的指示方法能够指示第二类DMRS映射类型(即增强后的DMRS映射类型)和第二类DMRS映射类型的DMRS端口信息,则可以支持多TRP下的相关联合传输,促进了多TRP相关联合传输的部署。
图5为本公开实施例所提供的一种信息指示方法的流程示意图,应用于网络设备,如图5所示,该信息指示方法可以包括以下步骤:
步骤501、响应于网络设备需要指示第二类DMRS映射类型下的DMRS type,确定第二类DMRS映射类型下的各DMRS type的第一对应关系。
其中,在本公开的一个实施例之中,该第一对应关系可以为:DCI信令的端口(Antenna port)指示域取值与DMRS端口信息之间的对应关系。以及,关于第二类DMRS映射类型下的各DMRS type以及DMRS端口信息的介绍可以参考上述实施例描述,本公开实施例在此不做赘述。
以及,在本公开的一个实施例之中,针对于新引入的第二类DMRS映射类型下的各DMRS type,会重新设计DCI信令的端口指示域取值与DMRS端口信息的第一对应关系。
需要说明的是,当DMRS type不同,或,DMRS type的符号长度不同时,第一对应关系也会有所不同。以及,表1示出了第二类DMRS映射类型下,DMRS type为:dmrs-Type=1(即DMRS type为DMRS type1对应的增强后的DMRS type,如DMRS type3),maxLength=1(即符号长度为单符号)时的第一对应关系。
表1
Figure PCTCN2022093160-appb-000001
Figure PCTCN2022093160-appb-000002
可以理解的是,上面的表1中的每一个元素都是独立存在的,这些元素被示例性的列在同一张表格中,但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值,是不依赖于表1中任何其他元素值。因此本领域内技术人员可以理解,该表1中的每一个元素的取值都是一个独立的实施例。
其中,针对于第二类DMRS映射类型而言,当dmrs-Type=1,maxLength=1时所支持的端口数为8个,示例性的可以分别为端口0-7;以及,网络设备所指示的DMRS端口信息具体是从所支持的8个端口中任选M个,M为小于等于8的正整数。如表1所示,当Codeword 0 enabled,Codeword 1 disabled 时,为每个UE的数据信道分配的DMRS端口中最多包括4个端口(也即是从所支持的8个端口中最多可任选4个),当Codeword 0 enabled,Codeword 1 enabled时,每个UE对应的DMRS端口信息中包括的端口数应当属于[4,8](也即是从所支持的8个端口中最小可任选4个,且最多可任选4个)。
进一步地,上述表1中的value的值代表DCI信令的端口指示域取值;DMRS port(s)代表DMRS端口信息。如表1所示,针对于第二类DMRS映射类型下的dmrs-Type=1,maxLength=1而言,当One Codeword时,若DCI信令的端口指示域取值为9,则该DCI信令指示的DMRS端口信息为:DMRS端口0-2,也即是,将“dmrs-Type=1”支持的端口中的DMRS端口0-2分配给UE的数据信道。若DCI信令的端口指示域取值为30,则该DCI信令指示的DMRS端口信息为:DMRS端口0,2,4,6,也即是,将“dmrs-Type=1”支持的端口中的DMRS端口0,2,4,6分配给UE的数据信道。
其中,需要说明的是,上述表1中的Number of DMRS CDM group(s)without data具体是指:CDM(code division multiplexing,码分多路复用)group(组)中没有用于传输数据的CDM group(s)的数量。以及,该“Number of DMRS CDM group(s)without data”的取值与具体的DMRS映射类型相关。
此外,还需要说明的是,在本公开的一个实施例之中,当利用DCI信令的端口指示域指示第二类DMRS映射类型下的各DMRS type的DMRS端口信息时,由于第二类DMRS映射类型下的各DMRS type的支持的端口数多于第一类DMRS映射类型下的各DMRS type的支持的端口数。因此,第二类DMRS映射类型下的各DMRS type对应的可选端口组合会增多,也即是,第二类DMRS映射类型下的各DMRS type的DMRS端口信息的可选组合情况会增多(如上述表1所示One Codeword下的组合情况增加至了30种),此时应该增加DCI信令的端口指示域所占用的比特数,以使得DCI信令的端口指示域的取值个数能够匹配于第二类DMRS映射类型下的各DMRS type对应的可选端口组合。其中,表2为本公开实施例提供的一种第二类DMRS映射类型下的各DMRS type与DCI信令的端口指示域所占用的比特数之间的对应关系表。
表2
Figure PCTCN2022093160-appb-000003
可以理解的是,上面的表2中的每一个元素都是独立存在的,这些元素被示例性的列在同一张表格中,但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值,是不依赖于表2中任何其他元素值。因此本领域内技术人员可以理解,该表2中的每一个元素的取值都是一个独立的实施例。
如表2所示,响应于网络设备需要指示单符号DMRS type3,DCI信令的端口指示域所占用的比特数为5;响应于网络设备需要指示双符号DMRS type3,DCI信令的端口指示域所占用的比特数为6;响应于网络设备需要指示单符号DMRS type4,DCI信令的端口指示域所占用的比特数为6;响应于网络设备需要指示双符号DMRS type4,DCI信令的端口指示域所占用的比特数为7。
步骤502、基于第一对应关系向UE发送DCI信令以指示DMRS端口信息。
具体的,可以确定出需要指示的DMRS端口信息,基于第一对应关系确定出该需要指示的DMRS端口信息对应的端口指示域取值,并将该端口指示域取值通过DCI信令的端口指示域发送至UE。
示例的,针对于“第二类DMRS映射类型下的dmrs-Type=1,maxLength=1,One Codeword”的场景 而言,假设网络设备需要指示的DMRS端口信息为:端口0、1、4、5,则通过查询上述表1所示的第一对应关系可以确定端口指示域取值应为28,则可以使得DCI信令的端口指示域取值为28,并将DCI信令发送至UE。
综上所述,在本公开实施例提供的信息指示方法之中,网络设备会向UE指示UE的DMRS信息,其中,DMRS信息包括以下至少一种:DMRS映射类型、UE对应的DMRS端口信息;其中,DMRS映射类型包括以下的至少一种:第一类DMRS映射类型、第二类DMRS映射类型;其中,第二类DMRS映射类型为从支持端口数这一维度对第一类DMRS映射类型增强后的映射类型;DMRS端口信息为DMRS映射类型支持的端口中分配给UE的数据信道的DMRS端口。由此可知,在本公开实施例提供的指示方法能够指示第二类DMRS映射类型(即增强后的DMRS映射类型)和第二类DMRS映射类型的DMRS端口信息,则可以支持多TRP下的相关联合传输,促进了多TRP相关联合传输的部署。
图6为本公开实施例所提供的一种信息指示方法的流程示意图,应用于网络设备,如图6所示,该信息指示方法可以包括以下步骤:
步骤601、响应于网络设备需要指示第二类DMRS映射类型下的DMRS type,确定第一类DMRS映射类型下DMRS type的第二对应关系。
其中,在本公开的一个实施例之中,该第二对应关系为:DCI信令的端口指示域取值与DMRS端口信息之间的对应关系。该第二对应关系为网络设备出厂时存储至网络设备中的,或是根据3GPP通信标准确定的。以及,关于第一类DMRS映射类型下的各DMRS type以及DMRS端口信息的介绍可以参考上述实施例描述,本公开实施例在此不做赘述。
以及,该第二对应关系为现有存在的各DMRS type(或称为第一类DMRS映射类型下DMRS type)下DCI信令的端口指示域取值与DMRS端口信息之间的对应关系。并且,在本公开的一个实施例之中,DMRS type不同,或,DMRS type的符号长度不同时,第二对应关系也会有所不同。以及,表3示出了第一类DMRS映射类型下,DMRS type为:dmrs-Type=1(即现有技术中存在的DMRS type1),maxLength=1(即符号长度为单符号)时的第二对应关系。
表3
Figure PCTCN2022093160-appb-000004
可以理解的是,上面的表3中的每一个元素都是独立存在的,这些元素被示例性的列在同一张表格中,但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值,是不依赖 于表3中任何其他元素值。因此本领域内技术人员可以理解,该表3中的每一个元素的取值都是一个独立的实施例。
其中,针对于第一类DMRS映射类型而言,当dmrs-Type=1,maxLength=1时所支持的端口数为4个,示例性的可以分别为端口0-4;以及,网络设备所指示的DMRS端口信息具体是从所支持的4个端口中任选M个,M为小于等于4的正整数。
进一步地,上述表3中的value的值代表DCI信令的端口指示域取值;DMRS port(s)代表DMRS端口信息。如表3所示,针对于:第一类DMRS映射类型下的dmrs-Type=1,maxLength=1而言,若DCI信令的端口指示域取值为9,则该DCI信令指示的DMRS端口信息为:DMRS端口0-2,也即是,将“dmrs-Type=1”支持的端口中的DMRS端口0-2分配给UE的数据信道。
以及,上述表3中的Number of DMRS CDM group(s)without data具体是指:CDM(code division multiplexing,码分多路复用)group(组)中没有用于传输数据的CDM group(s)的数量。以及,该“Number of DMRS CDM group(s)without data”的取值与具体的DMRS映射类型相关。
步骤602、基于第二对应关系向UE发送DCI信令以向UE指示DMRS端口信息。
其中,在本公开的一个实施例之中,是复用第一类DMRS映射类型的第二对应关系来指示第二类DMRS映射类型的DMRS端口信息。
具体的,在本公开的一个实施例之中,复用第一类DMRS映射类型的第二对应关系来指示第二类DMRS映射类型的DMRS端口信息的方法可以为:
响应于网络设备需要指示的DMRS端口信息中包括多端口,该DMRS端口信息中包括的端口应属于同一TRP(Transmission/Receiption Point,传输接收点),以及,在DCI信令中包括一标识符B,其中,该标识符B用于指示DCI信令指示的DMRS端口信息为第一TRP的端口信息或第二TRP的端口信息。
该标识符B可以包括F比特,其中,F为正整数,当该标识符B为第一数值(如0)时,则表示DCI信令指示的DMRS端口信息为第一TRP的端口信息,当该标识符B为第二数值(如1)时,则表示DCI信令指示的DMRS端口信息为第二TRP的端口信息。
以及,需要说明的是,上述的第一TRP和第二TRP为网络设备指示的DMRS映射类型支持的端口所对应的TRP。具体而言,当DMRS映射类型支持的端口总数为N时,如DMRS映射类型支持的端口为端口0-(N-1),此时,DMRS映射类型支持的端口中的前N/2个端口对应第一TRP,后N/2个端口对应第二TRP,如端口0-(N/2-1)对应第一TRP、端口N/2-(N-1)对应第二TRP。
进一步地,在本公开的一个实施例之中,基于第二对应关系向UE发送DCI信令以向UE指示DMRS端口信息的方法主要可以包括:
响应于标识符指示DMRS端口信息为第一TRP的端口信息,DMRS端口信息实际指示的DMRS端口的ID(Identity,序号)为DMRS端口信息中包括的DMRS端口的ID;
响应于标识符指示DMRS端口信息为第二TRP的端口信息,DMRS端口信息实际指示的DMRS端口的ID为DMRS端口信息中包括的DMRS端口的ID与预设值的和;预设值为N/2,N为网络设备指示的第二类DMRS映射类型下的DMRS type支持的总端口数。
需要说明的是,复用3GPP标准中的相关技术的第二对应关系来指示增强的第二类DMRS映射类型的DMRS端口信息时,该第二对应关系应当为所要指示的增强的DMRS type对应的未增强的DMRS type的对应关系。例如,当要指示DMRS type3(即增强的DMRS type1)的DMRS端口信息时,具体是利用DMRS type3对应的未增强的DMRS type1的第二对应关系,来指示DMRS type3(即增强的DMRS type1)的DMRS端口信息。
以下以“复用未增强的DMRS type1的第二对应关系来指示增强的DMRS type1的DMRS端口信息”为例进行说明;其他情况下可以采用相同的设计思路,在此不再赘述。
其中,未增强的DMRS type1在单符号的情况可以支持4个端口,分别为端口ID#0-3,且其第二对应关系如表3所示,增强的DMRS type1(即DMRS type3)在单符号的情况可以支持8个端口(即N=8),分别为端口ID#0-7,且增强的DMRS type1支持的8个端口中的端口ID#0-3为第一TRP对应的端口信 息,增强的DMRS type1(即DMRS type3)支持的8个端口中的端口ID#4-7为第二TRP对应的端口信息。
基于此,结合表3,当利用未增强的DMRS type1的第二对应关系来指示增强的DMRS type1的DMRS端口信息时,若网络设备向UE发送的DCI信令的端口指示域取值为8,则说明该指示域取值对应的端口ID应该为:端口ID#2和端口ID#3。此时,当DCI信令中的标识符B为0,则说明DCI信令所实质指示的DMRS端口信息为第一TRP的端口信息,此时,DMRS端口信息实际指示的DMRS端口的ID就为DMRS端口信息中包括的DMRS端口的ID,即端口ID#2和端口ID#3;而若DCI信令中的标识符B为1,则说明DCI信令所实质指示的DMRS端口信息为第二TRP的端口信息,此时,DMRS端口信息实际指示的DMRS端口的ID就为DMRS端口信息中包括的DMRS端口的ID与预设值的和,其中,预设值为N/2=8/2=4,则,DMRS端口信息实际指示的DMRS端口的ID应为:端口ID#2+4=ID#6,和端口ID#3+4=ID#7。即,该预设值可以为端口的偏移值。
此外,还需要说明的是,在本公开的一个实施例之中,仅是复用“第一类DMRS映射类型的DCI信令的端口指示域取值与DMRS端口信息之间的第二对应关系”来指示第二类DMRS映射类型下的DMRS type的DMRS端口信息,而第一类DMRS映射类型的其他参数(如Number of DMRS CDM group(s)without data),则不会直接复用于第二类DMRS映射类型中,而是需要作出一些调整后再用于第二类DMRS映射类型中。
综上所述,在本公开实施例提供的信息指示方法之中,网络设备会向UE指示UE的DMRS信息,其中,DMRS信息包括以下至少一种:DMRS映射类型、UE对应的DMRS端口信息;其中,DMRS映射类型包括第一类DMRS映射类型和/或第二类DMRS映射类型,第二类DMRS映射类型为从支持端口数这一维度对第一类DMRS映射类型增强后的映射类型;DMRS端口信息为DMRS映射类型支持的端口中分配给UE的数据信道的DMRS端口。由此可知,在本公开实施例提供的指示方法能够指示第二类DMRS映射类型(即增强后的DMRS映射类型)和第二类DMRS映射类型的DMRS端口信息,则可以支持多TRP下的相关联合传输,促进了多TRP相关联合传输的部署。
