图1为本申请实施例适用的一种通信网络的结构示意图。通信系统包括终端设备101、终端设备102和网络侧设备103。其中,终端设备101和终端设备102也可以称作用户终端(User Equipment,UE),终端设备101和终端设备102可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant,PDA)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备。

终端设备101和终端设备102可以通过Uu接口与网络侧设备103进行数据传输。
目前,在终端设备通过PUSCH传输上行数据的过程中,PUSCH中的一个传输层最多对应一个SRS资源,因此传输效率较低。
基于此,本申请实施例提供了一种上行数据传输方法,终端设备SRS资源指示信息,SRS资源指示信息指示多个SRS资源,基于SRS资源指示信息,执行PUSCH传输,PUSCH传输包括第一传输层,第一传输层对应于多个SRS资源中的至少两个SRS资源。通过SRS资源指示信息指示的多个SRS资源,实现在一个传输层可以同时传输至少两个SRS资源,以此提高传输效率。
图2示出了本申请实施例提供的一种上行数据传输方法的流程示意图;该上行数据传输方法可以由终端设备执行,例如,由图1中的终端设备执行。如图2所示,该方法包括如下步骤:
步骤S201:接收SRS资源指示信息。
终端设备接收网络侧设备发送的SRS资源指示信息。其中,SRS资源指示信息用于指示多个SRS资源。示例性地,SRS资源指示信息可以携带在无线资源控制(Radio Resource Control,RRC)信令、媒体接入控制-控制单元(Medium Access Control-Control Element,MAC CE)信令或下行控制信息(Downlink Control Information,DCI)中。
步骤S202:基于SRS资源指示信息,执行PUSCH传输。
PUSCH传输包括第一传输层,第一传输层对应于多个SRS资源中的至少两个SRS资源。终端设备基于SRS资源指示信息,执行PUSCH传输,可以理解为,终端设备基于SRS资源指示信息,通过PUSCH传输数据或信号等内容。
示例性的,终端设备基于SRS资源指示信息,确定PUSCH对应的天线端口,并基于天线端口,执行PUSCH传输。
示例性的,终端设备基于SRS资源指示信息,确定PUSCH对应的预编码矩阵,基于预编码矩阵,执行PUSCH传输。
示例性的,终端设备基于SRS资源指示信息,确定PUSCH对应的空间滤波(即发送波束),按照空间滤波,执行PUSCH传输。
示例性的,终端设备基于SRS资源指示信息,确定PUSCH传输对应的SRS资源。可选的,终端设备基于确定出的SRS资源,确定PUSCH对应的天线端口、预编码矩阵、空间滤波和发送功率中的一项或多项,并基于PUSCH对应的天线端口、预编码矩阵、空间滤波和发送功率中的一项或多项,执行PUSCH传输。
在一些实施例中,PUSCH传输包括多个传输层,第一传输层为多个传输层中的部分传输层,例如,为一个传输层。在一些实施例中,第一传输层为PUSCH传输的所有传输层。
在一些实施例中,第一传输层可以对应于多个SRS资源中的至少两个SRS资源。此时,若第一传输层为PUSCH传输的所有传输层,PUSCH传输的所有传输层都对应于至少两个SRS资源。
在一些实施例中,至少两个SRS资源也可以为SRS资源指示信息指示的多个SRS资源,即第一传输层可以对应于SRS资源指示信息指示的多个SRS资源,或者说,第一传输层可以对应于SRS资源指示信息指示的所有SRS资源。此时,若第一传输层为PUSCH传输的所有层时,PUSCH的所有层的传输都对应于SRS资源指示信息指示的所有SRS资源。
示例性的,假设SRS资源指示信息指示4个SRS资源,PUSCH传输包 括2个传输层。在一些实施例中,上述2个传输层中的每个传输层均可以对应于2个SRS资源,在另一些实施例中,上述2个传输层也可以每个传输层分别对应于4个SRS资源中的2个SRS资源。
可选的,PUSCH传输的第一传输层对应于至少两个SRS资源包括以下至少一项:
PUSCH传输的第一传输层的比特流被映射至至少两个SRS资源对应的天线端口。例如,通过预编码矩阵实现传输层到天线端口的映射;
在传输PUSCH传输的第一传输层的比特流时使用的预编码矩阵基于至少两个SRS资源对应的SRS确定;
在传输PUSCH传输的第一传输层的比特流时使用的空间滤波(即发送波束)基于至少两个SRS资源对应的SRS确定;
在传输PUSCH传输的第一传输层的比特流时使用的发送功率基于至少两个SRS资源对应的功控参数确定。
通过将PUSCH传输的一个层对应到至少两个SRS资源,本实施例可以实现基于至少两个包括较少天线端口的SRS资源,实现较多天线端口的映射。从而实现更多端口数的PUSCH传输。此外,通过较少天线端口的SRS资源实现较多天线端口,还可以使得SRS的传输具有更高的发送功率,从而提高上行信道状态信息(Channel State Information,CSI)获取的精度,增强上行覆盖。
在一种可能的实施例中,至少两个SRS资源中的每个SRS资源具有相同的天线端口数。
示例性地,在一些实施例中,第一传输层对应的至少两个SRS资源中的每个SRS资源具有相同的天线端口数。假设第一传输层对应于两个SRS资源,分别为第一SRS资源和第二SRS资源,则第一SRS资源的天线端口数等于第二SRS资源的天线端口数。例如,第一SRS资源的天线端口数和第二SRS资源的天线端口数可以均为4。在该实施例下,通过限制至少两个SRS资源中的每个SRS资源都具有相同的天线端口数,可以使得至少两个SRS资源对 应的各天线端口具有相同的传输功率,从而更好地获取PUSCH各天线端口的CSI信息。
在另一些实施例中,SRS资源指示信息指示的多个SRS资源中的每个SRS资源具有相同的天线端口数。假设SRS资源指示信息指示10个SRS资源,则10个SRS资源中每个SRS资源具有相同的天线端口数。
在另一种可能的实施例中,第一SRS资源的天线端口数也可以不等于第二SRS资源的天线端口数,如,第一SRS资源的天线端口数为4,第二SRS资源的天线端口数为2。
在一种可能的实施例中,多个SRS资源中至少一个SRS资源的天线端口的索引基于多个SRS资源中除SRS资源之外的其他至少一个SRS资源的天线端口数确定。
在一种可能的实施例中,多个SRS资源中的至少一个SRS资源的天线端口的编号(index)是基于多个SRS资源中其他至少一个的SRS资源的天线端口数确定的。
其中,上述内容中的编号可以理解为索引。
示例性地,以多个SRS资源中的第K个SRS资源为例,第K个SRS资源的天线端口的编号可以基于多个SRS资源中一个或多个SRS资源的天线端口数确定,此处的任意一个或多个SRS资源可以为第K个SRS资源前面的SRS资源,或第K个SRS资源后面的SRS资源。
在一些实施例中,第K个SRS资源的天线端口的编号可以基于前K-1个SRS资源的天线端口数确定的,K为大于1的正整数。
仍以第一SRS资源和第二SRS资源为例,假设第一SRS资源的天线端口数为N,则第二SRS资源第i个天线端口的编号为C+i+N-1,其中,C为一个常数,可选的,C=1000,即第二SRS资源的第i个天线端口的编号为1000+i+N-1。
在一些实施例中,多个SRS资源是SRS资源指示信息从SRS资源集合中指示的SRS资源。SRS资源集合中的至少一个SRS资源的天线端口的编号 (index)是基于SRS资源集合中其他的SRS资源的天线端口数确定的。
在一种可能的实施例中,多个SRS资源为同一个SRS资源集合中的SRS资源,SRS资源集合中至少一个SRS资源的天线端口的索引基于SRS资源集合中除该SRS资源之外的其他至少一个SRS资源的天线端口数确定。示例性的,SRS资源集合包括M个SRS资源,其中第T个SRS资源的第i个天线端口的编号为其中,C为一个常数,mt为第t个SRS资源包括的天线端口数,T为大于1的正整数。可选的,SRS资源集合中第1个SRS资源包括的第i个天线端口的编号为C+i-1。
在一种可能的实施例中,多个SRS资源为多个SRS资源集合中的SRS资源,多个SRS资源集合中至少一个SRS资源集合内的SRS资源的天线端口的索引基于多个SRS资源集合中除该SRS资源集合之外的其他至少一个SRS资源集合中的SRS资源包括的天线端口数确定。示例性的,多个SRS资源集合为M个SRS资源集合,其中第T个SRS资源集合中的一个SRS资源的第i个天线端口的编号为其中,C为一个常数,mt为第t个SRS资源集合中的一个SRS资源包括的天线端口数,T为大于1的正整数。可选的,多个SRS资源集合中第1个SRS资源集合中的SRS资源包括的第i个天线端口的编号为C+i-1。
通过上述实施例的方案,可以实现多个SRS资源的天线端口的区分,从而更好地实现一个PUSCH传输层对应于多个SRS资源。
在一种可能的实施例中,承载SRS资源指示信息的信令包括一个信息域,信息域用于指示多个SRS资源;或者,承载SRS资源指示信息的信令包括多个信息域,多个信息域中的每个信息域用于指示多个SRS资源中的一个SRS资源。即,多个SRS资源的指示可以通过同一个信息域实现,或者,多个SRS资源的指示通过多个信息域指示,每个信息域指示一个SRS资源。
可选的,信息域为SRS资源指示域。
在一种可能的实施例中,以SRS资源指示信息携带在DCI中为例,DCI中还可以包括一个信息域,此信息域用于指示多个SRS资源。
在一种可能的实施例中,SRS资源指示信息从多个SRS资源集合中指示SRS资源,多个SRS资源从一个SRS资源集合中进行指示。在本实施例中,可选的,信息域为SRS资源集合指示域,还可以用来指示SRS资源集合。可选的,SRS资源指示信息指示的不同的SRS资源从不同的SRS资源集合中进行指示。
若SRS资源指示信息是从SRS资源集合中指示SRS资源的,则可以通过信息域从第一SRS资源集合中指示第一SRS资源,从第二SRS资源集合中指示第二SRS资源。
其中,信息域可以理解为RRC信令、MAC CE信令、DCI信令中的字段、RRC信令中的参数。
在另一种可能的实施例中,以SRS资源指示信息携带在DCI中为例,DCI中可以包括多个信息域,多个信息域中的每个信息域用于指示一个SRS资源。
示例性地,DCI中有两个信息域,第一个信息域指示第一SRS资源,第二信息域指示第二SRS资源。
若SRS资源指示信息是从SRS资源集合中指示SRS资源的,则SRS资源指示信息可以包括2个信息域,第一信息域指示第一SRS资源,第二信息域指示第二SRS资源。其中,第一SRS资源可以是第一信息域从第一SRS资源集合中指示的SRS资源,第二SRS资源可以是第二信息域从第二SRS资源集合中指示的SRS资源。
在一种可能的实施例中,SRS资源指示信息包括SRS资源集合指示信息,SRS资源集合指示信息用于指示多个SRS资源对应的SRS资源集合。多个SRS资源对应的SRS资源集合可以是一个SRS资源集合,也可以是多个SRS资源集合。
以基站为终端设备配置了两个SRS资源集合为例,SRS资源集合指示信息的一个编码示例,如表1所示:
表1
例如,第一SRS资源和第二SRS资源属于同一个SRS资源集合,如表1中,SRS资源集合指示信息取值为0时,表示第一SRS资源和第二SRS资源都是第一SRS资源集合中的SRS资源;SRS资源集合指示信息取值为1时,表示第一SRS资源和第二SRS资源都是第二SRS资源集合中的SRS资源。
再例如,第一SRS资源和第二SRS资源属于不同的SRS资源集合,如表1中,SRS资源集合指示信息取值为2时,表示为第一SRS资源为第一SRS资源集合中的SRS资源,第二SRS资源为第二SRS资源集合中的SRS资源。
示例性地,SRS资源指示信息还可以包括第一SRS资源指示信息,第一SRS资源指示信息用于从SRS资源集合指示信息指示的SRS资源集合中指示多个SRS资源中的SRS资源。
例如,DCI携带的SRS资源指示信息中包括SRS资源集合指示信息和第一SRS资源指示信息。其中,SRS资源集合指示信息指示PUSCH传输对应的SRS资源集合,第一SRS资源指示信息从SRS资源集合指示信息指示的SRS资源集合中指示多个SRS资源对应的SRS资源。
在一种可能的实施例中,SRS资源指示信息至少包括第一信息域和第二信息域,第一信息域指示SRS资源集合,第二信息域指示SRS资源。这里的第一信息域可以理解为是SRS资源集合指示信息,第二信息域可以理解为第一SRS资源指示信息。
在一种可能的实施例中,SRS资源指示信息可以从同一个SRS资源集合中指示第一传输层对应的至少两个SRS资源。可以理解为,第一SRS资源和 第二SRS资源为同一个SRS资源集合中的SRS资源。
在另一种可能的实施例中,SRS资源指示信息可以从多个SRS资源集合中指示第一传输层对应的至少两个SRS资源。可以理解为,以至少两个SRS资源为第一SRS资源和第二SRS资源为例,则第一SRS资源属于第一SRS资源集合中的SRS资源,第二SRS资源属于第二SRS资源集合的SRS资源。
示例性地,SRS资源指示信息指示多个SRS资源集合,若多个SRS资源集合中的每个SRS资源集合中仅包括一个SRS资源,则SRS资源指示信息从每个SRS资源集合中仅指示一个SRS资源。
示例性地,SRS资源指示信息指示多个SRS资源集合,若多个SRS资源集合中的每个SRS资源集合中包括多个SRS资源,则SRS资源指示信息可以从每个SRS资源集合中指示多个SRS资源。
以SRS资源集合中包括两个SRS资源为例,两个SRS资源分别为第一SRS资源0和第二SRS资源1。SRS资源指示信息的一个编码示例,如表2所示:
表2
其中,SRI为探测参考信号资源指示(SRS resource indicator),即SRS资源指示信息。如表2所示,当SRS资源指示信息的取值为0时,指示了SRS资源集合中的一个SRS资源,即第一SRS资源0;当SRS资源指示信息的取值为1时,指示了SRS资源集合中的一个SRS资源,即第二SRS资源1;当SRS资源指示信息的取值为2时,指示了SRS资源集合中的两个SRS资源,即第一SRS资源0和第二SRS资源1。
在一种可能的实施例中,在SRS资源指示信息从多个SRS资源集合中指 示第一传输层对应的至少两个SRS资源的情况下,SRS资源指示信息从多个SRS资源集合中指示M个SRS资源,M为正整数。
示例性地,在一种实施例中,M=10时,SRS资源指示信息可以从3个SRS资源集合中指示10个SRS资源,10个SRS资源中的5个SRS资源可以属于同一个SRS资源集合,3个SRS资源可以属于同一个SRS资源集合,2个SRS资源可以属于同一个SRS资源集合。
在一种可能的实施例中,在SRS资源指示信息从多个SRS资源集合中指示至少两个SRS资源时,SRS资源指示信息从多个SRS资源集合中的第一SRS资源集合内指示M个SRS资源,M为正整数。
例如,M=1时,第一SRS资源集合内仅包括一个SRS资源,此时的SRS资源指示信息为SRS资源集合指示信息。

图4示出了另一种详细的进行上行数据传输的流程示意图,应用于终端设备,下述步骤中以执行PUSCH传输的过程中的第一传输层为例。步骤如下:
步骤S401:接收到SRS资源指示信息和预编码指示信息。
其中,SRS资源指示信息指示多个SRS资源。预编码指示信息包括第一预编码指示信息和第二预编码指示信息,第一预编码指示信息用于指示第一端口或第六SRS资源对应的第一预编码矩阵,第二预编码指示信息用于指示第二端口或第七SRS资源对应的第二预编码矩阵,第六SRS资源和第七SRS资源为多个SRS资源中的SRS资源,第一端口或第二端口为PUSCH传输对应的天线端口。

仍以第一SRS资源和第二SRS资源为例,假设第一SRS资源的天线端口数为N,则第二SRS资源第i个天线端口的编号为C+i+N-1,其中,C为一个常数,可选的,C=1000,即第二SRS资源的第i个天线端口的编号为1000+i+N-1。
在一些实施例中,多个SRS资源是SRS资源指示信息从SRS资源集合中指示的SRS资源。SRS资源集合中的至少一个SRS资源的天线端口的编号(index)是基于SRS资源集合中其他的SRS资源的天线端口数确定的。

在一种可能的实施例中,SRS资源指示信息从多个SRS资源集合中指示SRS资源,多个SRS资源从一个SRS资源集合中进行指示。在本实施例中,可选的,信息域为SRS资源集合指示域,还可以用来指示SRS资源集合。可选的,SRS资源指示信息指示的不同的SRS资源从不同的SRS资源集合中进行指示。
若SRS资源指示信息是从SRS资源集合中指示SRS资源的,则可以通过信息域从第一SRS资源集合中指示第一SRS资源,从第二SRS资源集合中指示第二SRS资源。
其中,信息域可以理解为RRC信令、MAC CE信令、DCI信令中的字段、RRC信令中的参数。
在另一种可能的实施例中,以SRS资源指示信息携带在DCI中为例,DCI中可以包括多个信息域,多个信息域中的每个信息域用于指示一个SRS资源。

在一种可能的实施例中,SRS资源指示信息包括SRS资源集合指示信息,SRS资源集合指示信息用于指示多个SRS资源对应的SRS资源集合。多个SRS资源对应的SRS资源集合可以是一个SRS资源集合,也可以是多个SRS资源集合。
以基站为终端设备配置了两个SRS资源集合为例,SRS资源集合指示信息的一个编码示例,如表3所示:
表3
例如,第一SRS资源和第二SRS资源属于同一个SRS资源集合,如表3中,SRS资源集合指示信息取值为0时,表示第一SRS资源和第二SRS资源都是第一SRS资源集合中的SRS资源;SRS资源集合指示信息取值为1时,表示第一SRS资源和第二SRS资源都是第二SRS资源集合中的SRS资源。
再例如,第一SRS资源和第二SRS资源属于不同的SRS资源集合,如表3中,SRS资源集合指示信息取值为2时,表示为第一SRS资源为第一SRS资源集合中的SRS资源,第二SRS资源为第二SRS资源集合中的SRS资源。
示例性地,SRS资源指示信息还可以包括第一SRS资源指示信息,第一SRS资源指示信息用于从SRS资源集合指示信息指示的SRS资源集合中指示多个SRS资源中的SRS资源。
例如,DCI携带的SRS资源指示信息中包括SRS资源集合指示信息和第 一SRS资源指示信息。其中,SRS资源集合指示信息指示PUSCH传输对应的SRS资源集合,第一SRS资源指示信息从SRS资源集合指示信息指示的SRS资源集合中指示多个SRS资源对应的SRS资源。
在一种可能的实施例中,SRS资源指示信息至少包括第一信息域和第二信息域,第一信息域指示SRS资源集合,第二信息域指示SRS资源。这里的第一信息域可以理解为是SRS资源集合指示信息,第二信息域可以理解为第一SRS资源指示信息。
在一种可能的实施例中,SRS资源指示信息可以从同一个SRS资源集合中指示第一传输层对应的至少两个SRS资源。可以理解为,第一SRS资源和第二SRS资源为同一个SRS资源集合中的SRS资源。
在另一种可能的实施例中,SRS资源指示信息可以从多个SRS资源集合中指示第一传输层对应的至少两个SRS资源。可以理解为,以至少两个SRS资源为第一SRS资源和第二SRS资源为例,则第一SRS资源属于第一SRS资源集合中的SRS资源,第二SRS资源属于第二SRS资源集合的SRS资源。
示例性地,SRS资源指示信息指示多个SRS资源集合,若多个SRS资源集合中的每个SRS资源集合中仅包括一个SRS资源,则SRS资源指示信息从每个SRS资源集合中仅指示一个SRS资源。
示例性地,SRS资源指示信息指示多个SRS资源集合,若多个SRS资源集合中的每个SRS资源集合中包括多个SRS资源,则SRS资源指示信息可以从每个SRS资源集合中指示多个SRS资源。
以SRS资源集合中包括两个SRS资源为例,两个SRS资源分别为第一SRS资源0和第二SRS资源1。SRS资源指示信息的一个编码示例,如表4所示:
表4

其中,SRI为探测参考信号资源指示(SRS resource indicator),即SRS资源指示信息。如表4所示,当SRS资源指示信息的取值为0时,指示了SRS资源集合中的一个SRS资源,即第一SRS资源0;当SRS资源指示信息的取值为1时,指示了SRS资源集合中的一个SRS资源,即第二SRS资源1;当SRS资源指示信息的取值为2时,指示了SRS资源集合中的两个SRS资源,即第一SRS资源0和第二SRS资源1。
在一种可能的实施例中,在SRS资源指示信息从多个SRS资源集合中指示第一传输层对应的至少两个SRS资源的情况下,SRS资源指示信息从多个SRS资源集合中指示M个SRS资源,M为正整数。
示例性地,在一种实施例中,M=10时,SRS资源指示信息可以从3个SRS资源集合中指示10个SRS资源,10个SRS资源中的5个SRS资源可以属于同一个SRS资源集合,3个SRS资源可以属于同一个SRS资源集合,2个SRS资源可以属于同一个SRS资源集合。
在一种可能的实施例中,在SRS资源指示信息从多个SRS资源集合中指示至少两个SRS资源时,SRS资源指示信息从多个SRS资源集合中的第一SRS资源集合内指示M个SRS资源,M为正整数。
例如,M=1时,第一SRS资源集合内仅包括一个SRS资源,此时的SRS资源指示信息为SRS资源集合指示信息。
例如,在RRC信令配置的SRS资源集合中只有一个SRS资源时,SRS资源指示信息为SRS资源集合的配置信息。
再例如,在RRC信令只配置了一个SRS资源集合时,SRS资源指示信息为SRS资源集合的配置信息。
在一种可能的实施例中,在SRS资源指示信息从多个SRS资源集合中指示至少第一传输层对应的两个SRS资源情况下,多个SRS资源集合为用途类型相同的SRS资源集合。
在一种可能的实施例中,在SRS资源指示信息指示多个SRS资源时,多个SRS资源为用途类型相同的SRS资源。
其中,在3GPP NR(New Radio)系统中,PUSCH传输模式可以为基于码本的PUSCH传输和基于非码本PUSCH传输两种。
例如,PUSCH为基于码本的PUSCH时,SRS资源为用途类型为码本的SRS资源,或,用途类型为码本的SRS资源集合中的SRS资源,上述SRS资源集合为用途类型为码本的SRS资源集合。即,在PUSCH传输为基于码本的传输时,SRS资源集合为用途(usage)被配置为“codebook”的SRS资源集合。
