图1是本公开实施例可应用的网络结构示意图;
图2是本公开实施例提供的一种指示消息传输方法的流程图;
图3是本公开实施例提供的一种通信设备的结构图;
图4是本公开实施例提供的另一种通信设备的结构图;
图5是本公开实施例提供的另一种通信设备的结构图。
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
参见图1,图1是本公开实施例可应用的网络结构示意图,如图1所示,包括终端11和网络侧设备12,终端11可以是用户终端(User Equipment,UE)或者其他终端设备,例如: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)、机器人、车辆等终端侧设备,需要说明的是,在本公开实施例中并不限定终端的具体类型。网络侧设备12可以是基站,例如:宏站、长期演进(Long Term Evolution,LTE)基站(eNB)、第五代(5
th Generation,5G)新空口(New Radio,NR)基站(NB)等;网络侧设备也可以是小站,如低功率节点(Low Power Node,LPN)、微微基站(pico)、毫微微基站(femto)等小站,或者网络侧设备可以是接入点(Access Point,AP);网络侧设备也可以是中央单元(Central Unit,CU),或者可以是传输接收点(Transmission Reception Point,TRP)等网络节点。需要说明的是,在本公开实施例中并不限定网络侧设备的具体类型。
本公开实施例中通信设备可以是终端或者网络侧设备。
参见图2,图2是本公开实施例提供的一种指示消息传输方法的流程图,该方法应用于通信设备,如图2所示,包括以下步骤:
步骤201、传输指示消息,所述指示消息包括如下一项或者多项:
探测参考信号SRS资源指示信息、预编码矩阵指示信息、传输流数指示信息和天线面板指示信息;
其中,所述指示消息包括的指示信息中至少一个指示信息为子带的指示信息。
其中,在上述通信设备为终端的情况下,步骤201可以是接收指示消息,在上述通信设备为网络侧设备的情况下,步骤201可以是发送指示消息。
所述指示消息用于所述终端根据所述指示消息,确定上行信号的传输参数和/或传输天线;以进一步利用所述传输参数和/或传输天线发送所述上行信号。
可选的,所述传输参数包括如下至少一项:
预编码矩阵、传输流数、空间相关信息和SRS资源;
所述传输天线包括如下至少一项:
发送天线和天线面板。
本公开实施例中,上述指示消息可以是无线资源控制(radio resource control,RRC)信令、媒体接入控制(Media Access Control,MAC)信令或者下行控制信息(Downlink Control Information,DCI)信令。或者上述RRC信令、MAC信令和DCI信令中任意两个或多个的组合。例如:SRI资源指示信息、传输流数指示信息和预编码矩阵指示信息在相同的DCI中指示;或者,SRI资源指示信息和传输流数指示信息在一个DCI,预编码矩阵指示信息在另一个DCI中;或者,预编码矩阵指示信息的一部分在一个DCI,另一部分在另一个DCI;或者SRI资源指示信息、传输流数指示信息和预编码矩阵指示信息其他组合方案等。
上述N个指示信息中至少一个指示信息为子带的指示信息可以理解为,上述指示消息包括的上述N个指示信息中存在一个或者多个指示信息为子带的指示信息,例如:指示消息包括SRS资源指示信息、预编码矩阵指示信息、 传输流数指示信息和天线面板指示信息,则可以是SRS资源指示信息、预编码矩阵指示信息、传输流数指示信息和天线面板指示信息中的至少一项为子带的指示信息。一个指示信息为子带的指示消息是指这个指示信息包含针对子带的指示。可以是这个指示信息是针对各个子带分别指示的,也可以是这个指示信息的一部分是对宽带(整个上行调度资源,或者整个BWP,或者整个上行带宽等)进行指示的,另一部分是针对子带进行指示的。以上行传输包含3个子带的子带TPMI为例,可以针对每个子带分别指示TPMI,例如,TPMI指示第一个子带的TPMI为TPMI=0,第二个子带的TPMI为TPMI=2,第三个子带的TPMI为TPMI=1;另一个示例为,TPMI包括宽带部分和子带部分,宽带部分用来指示预编码矩阵组,子带部分用来指示各个子带在这个预编码矩阵组中各自对应的预编码矩阵。
需要说明的是,本公开实施例中,SRS资源指示信息可以简称SRS资源指示(SRS resource indicator,SRI),而预编码矩阵指示信息可以简称传输预编码矩阵指示(Transmission precoding matrix indicator,TPMI)指示,而传输流数指示信息也可以理解为传输秩指示信息,简称传输秩指示(Transmission rank indicator,TRI)。SRS资源指示信息可以来指示上行信号传输对应的SRS资源。以上行信号为PUSCH为例,对于基于码本的PUSCH传输,PUSCH传输对应的SRS资源可以是SRS端口与PUSCH端口一一对应的SRS资源。所述SRS资源指示可以通过DCI中的SRS资源指示域(SRS resource indicator)来指示,也可以通过RRC信令srs-ResourceIndicator,或者MAC-控制单元(Control Element,CE)信令等来指示。预编码矩阵指示信息是用来指示上行信号传输对应的预编码矩阵的指示信息。当上行信号为PUSCH时,预编码矩阵指示信息可以通过DCI中的预编码矩阵指示和传输流数域(Precoding information and number of layers)来指示,也可以通过RRC信令precodingAndNumberOfLayers,或者MAC-CE信令等来指示。传输流数指示信息用来指示上行信号传输时的传输流数。当上行信号为PUSCH时,传输流数指示信息可以通过DCI中的预编码矩阵指示和传输流数域(Precoding information and number of layers)来指示,也可以通过RRC信令precodingAndNumberOfLayers,或者MAC-CE信令等来指示。
其中,当某一指示信息为子带的指示信息,则该指示信息所指示的内容用于对应的子带上。例如:网络侧设备对物理上行共享信道(Physical uplink shared channel,PUSCH)调度了3个子带,而上述指示消息包括3个子带的SRS资源指示信息,而每个子带的SRS资源为对应的指示信息所指示的SRS资源。
本公开实施例中,通过上述步骤可以实现传输子带的指示信息,从而提高调度的灵活性,例如:针对不同的子带可以调度不同的资源,或者调度不同的天线进行传输。
作为一种可选的实施方式,上述指示消息包括的SRS资源指示信息为子带的SRS资源指示信息,且多个子带的SRS资源指示信息所指示的SRS资源数相同。
其中,上述资源数相同可以是任意两个子带SRI指示的SRS资源包含的SRS端口数相同。例如,任意两个子带SRI指示的SRS资源包含的SRS端口数都是1。当然,对此不作限定,例如:任意两个子带SRI指示的SRS资源包含的SRS端口数可以相同或不同。
另外,上述资源数相同可以是任意两个子带SRI指示的SRS资源的数目相同,例如:任意两个子带SRI指示的SRS资源的数目都为1。
进一步的,实施方式可以是上述指示消息只包括SRS资源指示信息,且SRS资源指示信息是子带的,且任意两个子带SRI指示的SRS资源数相同。
可选的,只有PUSCH的传输为基于码本的传输方案时才采用本实施方式。或者,只有PUSCH的传输为基于码本的传输方案,且所有用于基于码本上行传输的SRS资源包含的天线端口数都是1时才采用本实施方式。或者,只有PUSCH的传输为非码本传输方案时才采用本实施方式。或者,无论PUSCH的传输方案为基于码本的传输方案还是非码本的传输方案都可以采用本实施方式。
由于该实施方式中,指示消息包括的SRS资源指示信息为子带的SRS资源指示信息,且多个子带的SRS资源指示信息所指示的SRS资源数相同,这样可以减少SRS资源数所需要的指示信息,以节约指示消息的开销。
作为一种可选的实施方式,所述指示消息包括的SRS资源指示信息为子 带的SRS资源指示信息,所述指示消息包括的预编码矩阵指示信息为宽带的预编码矩阵指示信息;或者

可选的,所述指示消息包括的预编码矩阵指示信息通过所述指示消息的预编码矩阵指示域指示;
在所述指示消息包括的预编码矩阵指示信息为宽带的预编码矩阵指示信息,所述指示消息包括的SRS资源指示信息为子带的SRS资源指示信息的情况下,所述预编码矩阵指示域中的一个预编码矩阵指示对应所述指示消息所有的SRS资源指示信息。
例如:上述预编码矩阵指示信息通过TPMI域指示,一个TPMI值对应于所有的SRI。这样可以节约指示消息的开销。
另外,上述在指示消息包括的SRS资源指示信息为子带的SRS资源指示信息的情况下,任意两个子带SRS资源指示信息的SRS资源包含的SRS端口数相同。当然,对此不作限定,例如:任意两个子带SRI指示的SRS资源包含的SRS端口数可以相同或不同。
可选的,上行信号在所有子带上的传输流数相同。这样可以减少指示消息中传输流指示信息的开销。例如:PUSCH在所有子带的传输流数相同,进一步的,上述传输流数是根据终端能力和/或网络侧设备的信令确定的,如根据是RRC信令,MAC CE信令或DCI等确定的。
作为一种可选的实施方式,所述指示消息包括的SRS资源指示信息为子带的SRS资源指示信息,所述指示消息包括的预编码矩阵指示信息为宽带的预编码矩阵指示信息,且所述指示消息包括的传输流数指示信息为宽带的传 输流数指示信息;或者

例如:所述预编码矩阵指示信息和传输流数指示信息通过预编码矩阵和传输流数指示域指示,一个预编码矩阵和传输流数指示的取值对应于所有的SRI。需要说明的是,这里的预编码矩阵和传输流数指示域是指一个域,而不是指预编码矩阵指示域,和传输流数指示域。由于通过一个域指示预编码矩阵指示信息和传输流数指示信息从而可以节约指示消息的开销。
可选的,所述指示消息包括的预编码矩阵指示信息为宽带的预编码矩阵指示信息,且所述指示消息包括的传输流数指示信息为宽带的传输流数指示信息,且在相同的预编码矩阵指示信息和传输流数指示信息下,上行信号在SRS资源指示信息指示的天线端口数不同的子带的预编码矩阵不同。
该实施方式可以是,在相同的预编码矩阵指示信息和传输流数指示信息 下,若SRS资源指示信息指示的SRS资源的天线端口数不同,则传输上行信号使用的预编码矩阵不同。
可选的,在所述指示消息包括的SRS资源指示信息为子带的SRS资源指示信息,所述指示消息包括的预编码矩阵指示信息为子带的预编码矩阵指示信息的情况下:
所述指示消息包括多个SRS资源指示信息和多个预编码矩阵指示信息,且多个SRS资源指示信息和多个预编码矩阵指示信息具有预定的对应关系,不同的SRS资源指示信息对应不同子带。
其中,上述预定对应关系可以是协议约定,网络侧设备配置给终端的,例如:一一对应关系,当然,对此不作限定,例如:也可以是一对多的关系。
进一步的,上述指示消息还可以包含多个SRS资源指示信息和多个预编码矩阵指示信息具有预定的对应关系。
作为一种可选的实施方式,所述指示消息中每个子带的指示信息各自对应一个子带:或者

所述指示消息包括的SRS资源指示信息的数目为所述SRS资源集合中包括的不同的空间相关信息的数目。
其中,空间相关信息是用来确定空间滤波的信息,如上述空间相关信息可以是用来指示模拟波束或空间滤波参数的指示信息。例如,空间相关信息可以指示参考信号,终端使用发送或接收所述参考信号的空间滤波器(Spatial filter)发送所述上行信号,即终端可以利用子带空间相关信息可以确定出发送所述上行信号的子带空间滤波参数。
另外,SRS资源的空间相关信息可以通过RRC信令、MAC信令、DCI信令等信令中的一个或多个进行指示。
上述SRS资源集合中包括的不同的空间相关信息的数目可以是,上述SRS资源集合中所有SRS资源对应的不同的空间相关信息。例如:上述SRS资源集合包括5个SRS资源,其中,SRS资源1和SRS资源2为空间相关信息1,SRS资源3、SRS资源4和SRS资源5为空间相关信息2,则SRS资源集合中包括的不同的空间相关信息的数目为2。
由于所述指示消息包括的SRS资源指示信息的数目为所述SRS资源集合 包括的SRS资源的数目,这样可以实现每个SRS资源单独指示;而所述指示消息包括的SRS资源指示信息的数目为所述SRS资源集合包括的SRS资源组的数目,可以实现每个SRS资源组单独指示,以节约指示消息的传输开销;而所述指示消息包括的SRS资源指示信息的数目为所述SRS资源集合中包括的不同的空间相关信息的数目,可以实现根据空间相关信息为指示,以节约指示消息的传输开销。
