  • a terminal can transmit SRS to the base station via an antenna (or antenna port, transmit antenna port). After receiving the SRS, the base station can estimate the uplink channel between the base station and the terminal based on the SRS measurement, thereby obtaining the uplink channel information.
  • SRS can only measure uplink channel information.
  • downlink channel information can be determined from uplink channel information, and SRS can also be used to determine downlink channel information.
  • SRS resources are various resources, such as time-frequency resources and periodic resources, configured by the base station for the terminal to transmit SRS.
  • the base station can configure multiple SRS resources for the terminal by configuring an SRS resource set. Furthermore, when configuring an SRS resource set, the base station can assign different purposes to the SRS resource set.
  • an SRS resource set can be configured for antenna switching (also known as antenna rotation). Since the number of transmit antenna ports and receive antenna ports of a terminal may not be the same (e.g., the number of transmit antenna ports is less than the number of receive antenna ports), the terminal's transmit and receive capabilities may differ. Therefore, to determine the channel information between each antenna port and the base station, the terminal can transmit SRS multiple times using different antenna ports based on the SRS resources in the SRS resource set used for Antenna Switching. Correspondingly, the base station can receive multiple SRS transmissions from different antenna ports of the terminal, thereby determining the channel information for the entire channel between the base station and the terminal.
  • the terminal transmits SRS through the SRS resources in the SRS resource set.

Subsequently, the base station can instruct the terminal to determine which precoding codebook to use for uplink transmission through the Transmit Precoding Matrix Indicator (TPMI) in the Downlink Control Information (DCI).

  • base stations When configuring SRS resources for terminals, base stations typically configure SRS resources suitable for terminals with one, two, or four transmit antenna ports, but not for terminals with three transmit antenna ports. Therefore, if the first node supports three transmit antenna ports (i.e., a three-antenna port terminal), the first node can receive SRS resource configurations from the second node. This allows it to configure an SRS resource group or SRS resources suitable for the first node's three-antenna ports, thus resolving the issue of how to configure corresponding SRS resources for terminals supporting three transmit antenna ports.

Subsequently, the first node can switch antenna ports and retransmit SRS. Thus, after multiple antenna port switching and SRS transmissions, all antenna ports of the first node have transmitted SRS. Since the second node can measure the channel information between the first and second nodes based on the received SRS, the second node, after receiving multiple SRS transmissions from the first node, can determine the channel information of the entire channel between itself and the first node based on these multiple SRS transmissions.

具体实施方式
下面将结合本公开中的附图,对本公开中的技术方案进行清楚、完整地描述。显然,所描述的实施例仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
需要说明的是,在本公开中,“示例性地”或者“例如”等词用于表示作例子、例证或说明。本公开中被描述为“示例性地”或者“例如”等的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性地”或者“例如”等词旨在以示例方式呈现相关概念。
以下,术语“第一”、“第二”等仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”等的特征可以明示或者隐含地包括一个或者更多个该特征。
在本公开的描述中,除非另有说明,“/”表示“或”的意思,例如,A/B可以表示A或B。本文中的“和/或”仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。此外,“至少一个”是指一个或多个,“多个”是指两个或两个以上。
SRS为无线通信中用于测量上行信道而配置的探测参考信号。终端可以通过天线(或者天线端口、发送天线端口)向基站发送SRS。基站接收到SRS后,可以基于SRS测量来估计基站与终端之间的上行信道,从而获取上行信道的信道信息。在频分双工系统中,SRS只能测量上行信道信息。但是,在时分双工系统中,由于上下信道具有互易性,因此,可以通过上行信道信息确定下行信道信息,SRS也可以用于确定下行信道信息。
SRS资源为基站为终端配置的用于传输SRS的时频资源、周期性等多种资源。基站可以通过配置SRS资源集为终端配置多个SRS资源。此外,在配置SRS资源集时,基站可以为SRS资源集配置不同的用途。
例如,SRS资源集的用途可以被配置为天线切换(Antenna Switching)(又可以称为天线轮发)。由于终端的发送天线端口的数目和接收天线端口的数目可能不一致(例如发送天线端口数量小于接收天线端口数量),从而导致终端的收发能力不同。因此,为了确定每个天线端口与基站之间的信道信息,终端可以基于用途为Antenna Switching的SRS资源集中的SRS资源,使用不同的天线端口多次发送SRS。相应的,基站可以接收终端的不同天线端口发送的多个SRS,从而可以确定基站与终端之间的全部信道的信道信息。
又例如,在SRS资源集被配置为码本(Codebook)时,终端通过SRS资源集中的SRS资源发送SRS,基站可以基于接收到的SRS确定信道信息,从而为终端选择最合适的码本。之后,基站可以通过下行控制信息(Downlink Control Information,DCI)中的传输预编码矩阵指示(Transmit Precoding Matrix Indicator,TPMI)指示终端确定哪个预编码码本进行上行传输。
此外,相关技术中一个SRS资源可以支持(或关联)一个、两个或四个天线端口,这样,终端可以基于该SRS资源支持的天线端口,通过该SRS资源传输SRS。
终端可以通过天线(也可称为天线端口)接收和发送信号。一般情况下,终端配置的天线为1天线、2天线、4天线。终端的发送天线端口和接收天线端口可以满足xTyR,xTyR是指x根发送天线(端口)和y根接收天线(端口),x和y均为正整数。一般情况下,终端的天线配置为:1T2R、1T4R、2T4R。例如,针对2T4R,终端配置了4根天线,在发送信号时,终端可以通过4根天线中的两根来发送。
然而,在考虑硬件和成本等因素情况下,终端一般不会配置太多的天线。因此,综合上行性能、成本以及硬件限制来说,终端通过三个天线端口进行上行传输是切实可行的方案。但是,对于这种终端来说,基站如何为三个天线端口的终端配置对应的SRS资源是目前亟待解决的技术问题。
对此,本公开实施例提供一种探测参考信号资源配置方法,第一节点可以接收SRS资源配置,该SRS资源配置至少用于配置一个SRS资源组,或者该SRS资源配置至少用于配置一个SRS资源。这样,在第一节点支持三个发送天线端口的情况下,第二节点可以基于SRS资源配置为第一节点配置上述SRS资源组或SRS资源,从而可以解决如何向三个发送天线端口的终端配置相适应的SRS资源的问题。
本公开实施例提供的探测参考信号资源配置方法,可以应用于多种通信制式的系统。例如,本公开实施例所提供的探测参考信号资源配置可以适用的系统包括但不限于长期演进(Long Term Evolution,LTE)系统、基于LTE演进的各种版本、第五代移动通信技术(5th Generation Mobile Communication Technology,5G)系统等通信系统中。此外,本公开实施例所提供的探测参考信号资源配置方法,还可以适用于面向未来的通信系统(例如6G通信系统)等。
示例性地,上述探测参考信号资源配置方法可以应用于如图1所述的通信系统中,如图1所示,该通信系统包括:第一节点101和第二节点102。
第一节点101和第二节点102通信连接。第一节点101可以为终端、物联网设备等。第二节点102可以为基站等。图1以第一节点101为终端、第二节点102为基站为例进行说明。
在本公开实施例中,第二节点102可以向第一节点101发送SRS资源配置。第一节点101可以接收SRS资源配置,从而确定第二节点102为第一节点101配置的SRS资源组或SRS资源。
需要说明的是,图1仅为示例性框架图,图1中包括的设备的数量,各个设备的名称不受限制,且除图1所示的设备外,通信系统还可以包括其他设备,如中继节点等。
本公开实施例的应用场景不做限定。本公开实施例描述的系统架构以及业务场景是为了更加清楚地说明本公开实施例的技术方案,并不构成对于本公开实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本公开实施例提供的技术方案对于类似的技术问题,同样适用。
下面将结合附图对本公开实施例提供的探测参考信号资源配置方法进行详细介绍。
本公开实施例提供的探测参考信号资源配置方法可以应用于图1所示的通信系统中的第一节点101。图2示出了一种探测参考信号资源配置方法的流程示意图,如图2所示,该探测参考信号资源配置方法包括以下S201和S202。
S201、接收SRS资源配置。
其中,SRS资源配置至少用于配置一个SRS资源组或者一个SRS资源。
在一些实施例中,第一节点支持三个发送天线端口。为了满足第一节点的需求,SRS资源配置所配置的SRS资源组可以为三天线端口的SRS资源组,SRS资源配置所配置的SRS资源可以为三天线端口的SRS资源。
SRS资源组包括一个或多个SRS资源。SRS资源组的天线端口的数目即为SRS资源组中所有SRS资源的天线端口的数目总和。例如,SRS资源组包括一个单天线端口的SRS资源和一个两天线端口的SRS资源,该SRS资源组即为三天线端口的SRS资源。又例如,SRS资源组包括两个单天线端口的SRS资源,该SRS资源组即为两天线端口的SRS资源组。
基站在为终端配置SRS资源时,配置的SRS资源一般都是适合一个发送天线端口、两个发送天线端口或四个发送天线端口的终端,而没有适应于三个天线发送端口的终端。因此,在第一节点支持三个发送天线端口(即三天线端口的终端)的情况下,第一节点可以接收第二节点发送的SRS资源配置,从而可以配置适应于第一节点的三天线端口的SRS资源组或三天线端口的SRS资源,可以解决如何向支持三个发送天线端口的终端配置对应的SRS资源的问题。
S202、第一节点基于SRS资源配置发送SRS。
在一种可能的实现方式中,SRS资源配置所配置的SRS资源或者SRS资源组还可以用于天线切换。第一节点在接收到SRS资源配置之后,可以基于配置的三天线端口的SRS资源(或资源组),通过三个发送天线端口发送SRS。之后,第一节点还可以切换天线端口重新发送SRS。这样,在多次切换天线端口发送SRS后,第一节点的全部天线端口均发送了SRS。由于第二节点可以基于接收到的SRS测量第一节点与第二节点之间的信道信息,因此,第二节点在接收到第一节点发送的多个SRS之后,可以基于多个SRS确定其与第一节点之间的全部信道的信道信息。
接下来,将对SRS资源配置中配置的SRS资源和SRS资源组进行介绍。
(1)三天线端口的SRS资源组
在一些实施例中,所述三天线端口的SRS资源组包括如下之一:一个单天线端口的SRS资源和一个两天线端口的SRS资源;或者,三个单天线端口的SRS资源。
单天线端口的SRS资源指的是,该SRS资源支持(或关联)第一节点的一个天线端口。双天线端口的SRS资源指的是,该SRS资源支持(或关联)第一节点的两个天线端口。三天线端口的SRS资源组指的是,该SRS资源组中的SRS资源支持(或关联)第一节点的三个天线端口。这样,第一节点可以基于三天线端口的SRS资源组在三个发送天线端口上发送SRS。
在一些实施例中,SRS资源组满足以下至少一项:同一SRS资源组中的SRS资源属于同一个SRS资源集或者不同的SRS资源集;不同SRS资源组中的SRS资源属于同一个SRS资源集或者不同的SRS资源集;同一SRS资源组中的SRS资源占用相同的频域资源;不同SRS资源组中的SRS资源占用相同的频域资源;同一SRS资源组中的SRS资源占用相同的时域资源或不同的时域资源;不同SRS资源组中的SRS资源占用相同的时域资源或不同的时域资源。
在一种可能的实现方式中,由于第二节点向第一节点配置SRS资源时,是通过配置SRS资源集实现的。因此,第二节点在配置SRS资源组时可以有多种配置方式。SRS资源组中的多个SRS资源可以是属于同一SRS资源集的,又可以是属于完全不同的SRS资源集的,还可以是属于部分不同的SRS资源集的。例如,为了配置一个三天线端口的SRS资源组,可以采用以下方式之一:(方式一)配置一个SRS资源集,该SRS资源集包括三个单天线端口的SRS资源;(方式二)配置两个SRS资源集,其中一个SRS资源集包括一个单天线端口的SRS资源,另一个SRS资源集包括一个两天线端口的SRS资源;(方式三)配置三个SRS资源集,每个SRS资源集中包括一个单天线端口的SRS资源。本公开实施例不限于此。
此外,SRS资源占用的时域资源或频域资源是指,第一节点在基于该SRS资源传输SRS时,SRS所占用的时域资源或频域资源。SRS资源组中的SRS资源占用不同的时域资源可以为,占用的时域资源部分不同或占用的时域资源完全不同。可选的,时域资源包括时域符号,和\或,时隙。
(2)三天线端口的SRS资源
在一些实施例中,三天线端口的SRS资源由四天线端口的SRS资源放弃一个天线端口得到。第二节点在配置四天线端口的SRS资源时,可以丢弃其中一个天线端口不使用(或者说默认与第一节点的天线端口不关联),从而得到三天线端口的SRS资源。这样,可以不用新增一种SRS资源类型,而是通过沿用相关协议中的设计,以保证兼容性。
在一些实施例中,可以新增一种SRS资源类型,也即三天线端口的SRS资源。
以上为对三天线端口的SRS资源和三天线端口的SRS资源组的介绍,由于SRS资源配置至少用于配置一个三天线端口的SRS资源或一个三天线端口的SRS资源组,因此,SRS资源配置的配置内容与第一节点的天线收发能力相关。以下将以不同种类的天线收发能力的第一节点分别介绍SRS资源配置的配置内容。
在一些实施例中,第一节点需要向第二节点上报(或发送)自己的天线收发能力,以使得第二节点可以根据第一节点的天线收发能力配置SRS资源。天线收发能力包括以下任意一项:3T3R、3T4R、3T6R、3T8R。
种类一、第一节点被配置为3T3R:
SRS资源配置用于配置一个三天线端口的SRS资源组或者一个三天线端口的SRS资源。
由于第一节点包括三个天线端口,且第一节点每次发送SRS均是通过三个天线端口发送,因此,第一节点只需要发送一次就可以使第二节点基于SRS测量出全部信道的信道信息。这样,由于三天线端口的SRS资源组或者三天线端口的SRS资源支持的天线端口对应第一节点的三个不同的发送天线端口,因此,第一节点可以基于SRS资源配置,分别通过三个天线端口发送SRS,从而无需重新发送。
在一些实施例中,SRS资源配置最多用于配置三个SRS资源集或三个SRS资源。
种类二、第一节点被配置为3T4R:
SRS资源配置用于配置以下任一项:
两个三天线端口的SRS资源组;
两个三天线端口的SRS资源;
一个三天线端口的SRS资源组和一个三天线端口的SRS资源;
一个三天线端口的SRS资源组和一个单天线端口的SRS资源;
一个三天线端口的SRS资源和一个单天线端口的SRS资源。
由于第一节点包括四个天线端口,因此,在第一节点支持三个发送天线端口的情况下,第一节点一次只能通过三个天线端口发送SRS,因此,第一节点至少需要发送两次SRS才能使所有的发送天线端口均发送SRS。在这种情况下,SRS资源支持的天线端口,至少对应第一节点的四个发送天线端口。
作为一个示例,SRS资源配置可以用于配置以下任一项:两个三天线端口的SRS资源组;两个三天线端口的SRS资源;一个三天线端口的SRS资源组和一个三天线端口的SRS资源。在这种情况下,SRS资源配置的SRS资源支持的天线端口数量为6个,这六个天线端口对应第一节点的四个发送天线端口,因此,这六个天线端口对应的第一节点的发送天线端口有部分重叠。例如,假设第一节点的发送天线端口的索引为0、1、2、3,SRS资源配置用于配置两个三天线端口的SRS资源组,第一个SRS资源组支持的三个天线端口对应的第一节点的三个发送天线端口为0、1、2,第二个SRS资源组支持的三个天线端口对应的第一节点的三个发送天线端口必须包括3,例如为1、2、3,其中,1、2为重叠的发送天线端口。
此外,两个三天线端口的SRS资源(或资源组)占用相同的频域资源以及不同的时域资源,或者,一个三天线端口的SRS资源组和一个三天线端口的SRS资源,占用相同的频域资源以及不同的时域资源,三天线端口的SRS资源组内的多个SRS资源占用相同的频域资源以及相同的时域资源。
作为又一个示例,SRS资源配置可以用于配置以下任一项:一个三天线端口的SRS资源组和一个单天线端口的SRS资源;一个三天线端口的SRS资源和一个单天线端口的SRS资源。在这种情况下,SRS资源配置的SRS资源支持的天线端口数量为4个,这四个天线端口分别对应第一节点的四个发送天线端口。例如,假设第一节点的发送天线端口的索引为0、1、2、3,SRS资源配置用于配置一个三天线端口的SRS资源和一个单天线端口的SRS资源时,三天线端口的SRS资源支持的三个天线端口对应第一节点的发送天线端口0、1、2,单天线端口的SRS资源支持的一个天线端口对应第一节点的发送天线端口3。
此外,多个三天线端口的SRS资源(或资源组)占用相同的频域资源以及不同的时域资源,三天线端口的SRS资源组内的多个SRS资源占用相同的频域资源以及相同的时域资源。
种类三、第一节点的天线收发能力被配置为3T6R:
SRS资源配置用于配置以下任一项:
两个三天线端口的SRS资源组;
两个三天线端口的SRS资源;
一个三天线端口的SRS资源组和一个三天线端口的SRS资源。
由于第一节点包括六个天线,因此,第一节点至少需要发送两次SRS才能使所有的发送天线端口均发送SRS。在这种情况下,SRS资源支持的天线端口,至少对应第一节点的六个发送天线端口。
示例性地,SRS资源配置用于配置的SRS资源的六个天线端口分别对应于第一节点的六个发送天线端口,且没有重复的部分。例如,假设第一节点的发送天线端口的索引为0、1、2、3、4、5,SRS资源配置用于配置两个三天线端口的SRS资源时,第一个三天线端口的SRS资源支持的天线端口对应第一节点的三个发送天线端口0、1、2,第二个三天线端口的SRS资源支持的天线端口对应第一节点的三个发送天线端口3、4、5。
此外,两个三天线端口的SRS资源(或资源组)占用相同的频域资源以及不同的时域资源,或者,一个三天线端口的SRS资源组和一个三天线端口的SRS资源,占用相同的频域资源以及不同的时域资源。三天线端口的SRS资源组内的多个SRS资源占用相同的频域资源以及相同的时域资源。
种类四、第一节点的天线收发能力被配置为3T8R:
SRS资源配置用于配置以下任一项:
三个三天线端口的SRS资源组;
三个三天线端口的SRS资源;
两个三天线端口的SRS资源组和一个三天线端口的SRS资源;
一个三天线端口的SRS资源组和两个三天线端口的SRS资源组;
两个三天线端口的SRS资源组和一个两天线端口的SRS资源;
两个三天线端口的SRS资源和一个两天线端口的SRS资源组;
两个三天线端口的SRS资源和一个两天线端口的SRS资源。
由于第一节点包括八个天线端口,因此,第一节点至少需要发送三次SRS才能使所有的发送天线端口均发送SRS。在这种情况下,SRS资源支持的天线端口,至少对应第一节点的八个发送天线端口。
示例性地,SRS资源配置可以用于配置以下任一项:三个三天线端口的SRS资源组;三个三天线端口的SRS资源;两个三天线端口的SRS资源组和一个三天线端口的SRS资源。在这种情况下,SRS资源配置用于配置的SRS资源的九个天线端口至少对应于第一节点的八个发送天线端口,因此,SRS资源配置用于配置的三个SRS资源(或资源组)支持的天线端口对应的第一节点的发送天线端口,可以为部分不同,也可以为完全不同。例如,假设第一节点的发送天线端口的索引为0、1、2、3、4、5、6、7,SRS资源配置用于配置三个三天线端口的SRS资源时,第一个三天线端口的SRS资源支持的天线端口对应第一节点的三个发送天线端口0、1、2,第二个三天线端口的SRS资源支持的天线端口对应第一节点的三个发送天线端口3、4、5,第三个三天线端口的SRS资源支持的天线端口对应第一节点的三个发送天线端口6、7、2。
此外,多个三天线端口的SRS资源(或资源组)占用相同的频域资源以及占用不同的时域资源,SRS资源组内的SRS资源占用相同的频域资源以及相同的时域资源。
又一示例性地,SRS资源配置可以用于配置以下任一项:一个三天线端口的SRS资源组和两个三天线端口的SRS资源组;两个三天线端口的SRS资源组和一个两天线端口的SRS资源;两个三天线端口的SRS资源和一个两天线端口的SRS资源组;两个三天线端口的SRS资源和一个两天线端口的SRS资源。在这种情况下,SRS资源配置的配置内容配置的SRS资源支持的天线端口的数量为八个,分别对应第一节点的八个发送天线端口,且没有重复的部分。例如,假设第一节点的发送天线端口的索引为0、1、2、3、4、5、6、7,SRS资源配置用于配置两个三天线端口的SRS资源和一个双天线端口的SRS资源时,第一个三天线端口的SRS资源支持的天线端口对应第一节点的三个发送天线端口0、1、2,第二个三天线端口的SRS资源支持的天线端口对应第一节点的三个发送天线端口3、4、5,双天线端口的SRS资源支持的天线端口对应第一节点的三个发送天线端口6、7。
此外,三天线端口的SRS资源(或资源组)和双天线端口的SRS资源占用相同的频域资源以及占用不同的时域资源,SRS资源组内的SRS资源占用相同的频域资源以及相同的时域资源。
第一节点在接收到SRS资源配置之后,可以基于SRS资源配置发送SRS。然而,在传输SRS时,第一节点可能会发生SRS资源冲突的情况,以下将对SRS资源冲突的解决方法进行介绍。
在一些实施例中,在第一SRS资源和第二SRS资源冲突的情况下,在第一SRS资源上传输SRS,放弃在第二SRS资源的全部资源或者冲突资源上传输SRS。
其中,第一SRS资源的优先级高于第二SRS资源的优先级;第二SRS资源的冲突资源为第二SRS资源中与第一SRS资源重叠的部分资源。示例性地,第一SRS资源和第二SRS资源可以包括上述三天线端口的SRS资源或三天线端口的SRS资源组。
第二节点可以为第一节点配置多个SRS资源,并配置基于该多个SRS资源传输的SRS为非周期性或半持续性或周期性。然而,在多个SRS资源被配置为在同一时域资源上传输至少两种不同类型的SRS时,第一节点基于这多个SRS资源传输SRS时会发生冲突,导致第二节点无法成功接收第一节点发送的SRS。例如,当第一SRS资源被配置为在时域符号9上传输非周期性SRS,且第二SRS资源被配置为在时域符号9和时域符号10上传输周期性SRS时,第一SRS资源和第二SRS资源均被配置为在时域符号9上传输SRS,且传输的SRS种类不同,也即,第一节点同时在时域符号9上传输非周期性信号和周期性信号,此时,第一节点在第一SRS资源和第二SRS资源上发生冲突。例如,第一SRS资源和第二SRS资源可以为传输SRS的时域资源。
在这种情况下,第一节点可以基于优先级确定优先级最高的第一SRS资源,并在冲突资源(例如SRS所在的符号)被触发传输时,基于第一SRS资源传输SRS。此外,第一节点还可以放弃在第二SRS资源上传输SRS,即不通过第二SRS资源传输SRS。
或者,第一节点也可以仅放弃在第二SRS资源中的冲突SRS资源传输SRS,而第二SRS资源中的其它资源仍然可以继续传输SRS。例如,在第一SRS资源被配置为基于时域符号9传输非周期性SRS,且第二SRS资源被配置为在时域符号9和时域符号10传输周期性或半持续性SRS的情况下,由于第二SRS资源中的时域符号9与第一SRS资源中的时域符号9为相同的时域资源,且第一SRS资源中的时域符号9传输的SRS种类与第二SRS资源中的时域符号9传输的SRS种类不同,因此,可以确定第一SRS资源与第二SRS资源发生冲突,并确定第二SRS资源中,与第一SRS资源中发生重叠的冲突资源为时域符号9,并放弃在第二SRS资源的时域符号9传输SRS,第二SRS资源中的时域符号10正常传输。
在一种可能的实现方式中,SRS资源的优先级可以基于SRS所配置的SRS的种类确定。例如,非周期性SRS的优先级高于半持续性SRS高于周期性SRS。具体到第一SRS资源和第二SRS资源,第一SRS资源为非周期性的SRS资源,第二SRS资源为半持续性的SRS资源或者周期性的SRS资源;或者,第一SRS资源为半持续的SRS资源,第二SRS资源为周期性的SRS资源。
以下将结合四个示例,分别描述上述两种解决冲突的方法:
示例一:在第一SRS资源上传输SRS,放弃在第二SRS资源的全部资源上传输SRS。
在第一SRS资源被配置为基于时域符号9传输非周期性SRS,且第二SRS资源被配置为在时域符号9和时域符号10传输周期性或半持续性SRS的情况下,由于第二SRS资源中的时域符号9与第一SRS资源中的时域符号9为相同的时域资源(即发生重叠),且第一SRS资源中的时域符号9传输的SRS种类与第二SRS资源中的时域符号9传输的SRS种类不同,因此,可以确定第一SRS资源与第二SRS资源发生冲突。这样,在传输非周期性SRS的时域符号9被触发时,第一节点仍然基于时域符号9传输非周期性SRS,并放弃在时域符号9和时域符号10上传输周期性或半持续性SRS。上述第一SRS资源为单天线端口SRS资源,被配置为在一个时域符号上传输SRS,第二SRS资源为双天线端口SRS资源或者两个单天线端口的SRS资源,被配置为在两个时域符号上传输SRS。
示例二、在第一SRS资源上传输SRS,放弃在第二SRS资源的冲突资源上传输SRS。
在第一SRS资源被配置为基于时域符号9传输非周期性SRS,且第二SRS资源被配置为在时域符号9和时域符号10传输周期性或半持续性SRS的情况下,由于第二SRS资源中的时域符号9与第一SRS资源中的时域符号9为相同的时域资源(即发生重叠),且第一SRS资源中的时域符号9传输的SRS种类与第二SRS资源中的时域符号9传输的SRS种类不同,因此,可以确定第一SRS资源与第二SRS资源发生冲突,且冲突资源为时域符号9。这样,在传输非周期性SRS的时域符号9被触发时,第一节点仍然基于时域符号9传输非周期性SRS,并放弃在时域符号9上传输周期性或半持续性SRS。上述第一SRS资源为单天线端口SRS资源,被配置为在一个时域符号上传输SRS,第二SRS资源为双天线端口SRS资源或者两个单天线端口的SRS资源,被配置为在两个时域符号上传输SRS。
示例三:在第一SRS资源上传输SRS,放弃在第二SRS资源的全部资源上传输SRS。
在第一SRS资源被配置为基于时域符号9传输半持续性SRS,且第二SRS资源被配置为在时域符号9和时域符号10传输周期性SRS的情况下,由于第二SRS资源中的时域符号9与第一SRS资源中的时域符号9为相同的时域资源(即发生重叠),且第一SRS资源中的时域符号9传输的SRS种类与第二SRS资源中的时域符号9传输的SRS种类不同,因此,可以确定第一SRS资源与第二SRS资源发生冲突。这样,在传输半持续性SRS的时域符号9被触发时,第一节点仍然基于时域符号9传输半持续性SRS,并放弃在时域符号9和时域符号10上传输周期性SRS。上述第一SRS资源为单天线端口SRS资源,被配置为在一个时域符号上传输SRS,第二SRS资源为双天线端口SRS资源或者两个单天线端口的SRS资源,被配置为在两个时域符号上传输SRS。
示例四、在第一SRS资源上传输SRS,放弃在第二SRS资源的冲突资源上传输SRS。
在第一SRS资源被配置为基于时域符号9传输半持续性SRS,且第二SRS资源被配置为在时域符号9和时域符号10传输周期性SRS的情况下,由于第二SRS资源中的时域符号9与第一SRS资源中的时域符号9为相同的时域资源(即发生重叠),且第一SRS资源中的时域符号9传输的SRS种类与第二SRS资源中的时域符号9传输的SRS种类不同,因此,可以确定第一SRS资源与第二SRS资源发生冲突,且冲突资源为时域符号9。这样,在传输半持续性SRS的时域符号9被触发时,第一节点仍然基于时域符号9传输半持续性SRS,并放弃在时域符号9上传输周期性SRS。上述第一SRS资源为单天线端口SRS资源,被配置为在一个时域符号上传输SRS,第二SRS资源为双天线端口SRS资源或者两个单天线端口的SRS资源,被配置为在两个时域符号上传输SRS。
在第一节点发送SRS之后,第二节点可以基于SRS确定信道状态,从而基于确定的信道状态为第一节点下发控制信息,以使得第一节点可以基于该控制信息进行上行传输。以下,将对第一节点基于第二节点下发的控制信息进行上行传输进行介绍。
需要指出的是,在三天线端口终端的场景下,相关技术中没有设计和指示部分相干传输码本的方法,因此,如何设计和指示部分相干传输码本也是目前亟待解决的技术问题。
在一些实施例中,第一节点接收预编码指示信息。预编码指示信息用于从三个发送天线端口的部分相干传输码本中指示码字。三个发送天线端口划分为第一天线端口组和第二天线端口组。其中,第一天线端口组包括两个发送天线端口,第二天线端口组包括一个发送天线端口。
部分相干传输码本中,与第一天线端口组相关的码本元素与两天线端口的全相干传输码本中的码本元素相同。
在一些实施例中,预编码指示信息可以承载于以下至少之一:无线资源控制(Radio Resource Control,RRC)信令、下行控制信息(Downlink Control Information,DCI)。
在一种可能的实现方式中,第一节点的三个发送天线端口中,两个发送天线端口组成第一天线端口组,剩下的一个发送天线端口为第二天线端口组。例如,第一天线端口组包括天线端口1(即第一个发送天线端口)和天线端口2(即第二个发送天线端口),第二天线端口组包括天线端口3;或者,第一天线端口组包括天线端口1和天线端口3(即第三个发送天线端口),第二天线端口组包括天线端口2;或者,第一天线端口组包括天线端口2和天线端口3,第二天线端口组包括天线端口1。
在SRS资源集的用途被配置为“codebook”的情况下,第二节点接收到SRS之后,可以确定信道状态,并基于测量的信道状态向第一节点发送预编码指示信息。针对于支持三个发送天线端口的第一节点的部分相干码本传输,第一节点接收到预编码指示信息后,可以基于预编码指示信息确定部分相干传输码本中指示码字,从而可以解决如何指示三天线端口的终端的码本的问题。其中,部分相干传输码本为第一节点的三个发送天线端口进行部分相干传输时使用的码本。
在一些实施例中,部分相干传输码本中,与第一天线端口组相关的非零码本元素,与两天线端口的全相干传输码本中的码本元素相同。
第一天线端口组在相干传输码本中的对应位置的非零码本元素,与两天线端口的全相干传输码本中的码本元素相同。第二天线端口组在相干传输码本中的对应位置的码本元素可以根据上行传输流数进行补0或者补1,并修正矩阵的系数。其中,预编码指示信息还可以指示上行传输流数。
在一些实施例中,对于任一传输流,部分相干传输码本中的非零码本元素与第一天线端口组或第二天线端口组相关。例如,上行传输流数可以为单流、双流、三流等。
在一些实施例中,对于单个传输流,部分相干传输码本中与第二天线端口组相关的码本元素为0,部分相干传输码本中,与第一天线端口组相关的码本元素(即上述非零码本元素)与单个传输流下的两天线端口的全相干传输码本中的码本元素相同。
在上行传输流数为1的情况下,第一节点可以采用第一天线端口组传输这个单传输流。因此,第一天线端口组在部分相干传输码本中的对应位置的码本元素,与两天线端口单流的全相干码本的码本元素相同。而由于仅需要通过第一天线端口组传输这单传输流,而第二天线端口组无需传输,因此,第二天线端口组在部分相干传输码本中的对应位置的码本元素为0。这样,可以解决如何设计和指示三天线端口终端的部分相干传输码本的问题。
示例性地,在第一天线端口组包括天线端口1和天线端口3,第二天线端口组包括天线端口2时,部分相干传输码本满足以下(公式1):
其中,j为虚数,上述矩阵公式中的第一行对应天线端口1,第二行对应天线端口2,第三行对应天线端口3。
在第一天线端口组包括天线端口1和天线端口2,第二天线端口组包括天线端口3时,部分相干传输码本满足以下(公式2):
其中,j为虚数,上述矩阵公式中的第一行对应天线端口1,第二行对应天线端口2,第三行对应天线端口3。
在第一天线端口组包括天线端口2和天线端口3,第二天线端口组包括天线端口1时,部分相干传输码本满足以下(公式3):
其中,j为虚数,上述矩阵公式中的第一行对应天线端口1,第二行对应天线端口2,第三行对应天线端口3。
在一些实施例中,对于两个传输流,部分相干传输码本中与第二天线端口组相关的码本元素(即上述非零码本元素)为1,部分相干传输码本中,与第一天线端口组相关的码本元素与单个传输流下的两天线端口的全相干传输码本中的码本元素相同。
在上行传输流数为2的情况下,第一节点可以采用第一天线端口组传输一个传输流,采用第二天线端口组传输另一个传输流。因此,第一天线端口组在部分相干传输码本中的对应位置的非零码本元素,与两天线端口单流的全相干码本的码本元素相同,第二天线端口组在部分相干传输码本中对应传输流的对应位置的码本元素为1,其余位置补0。
示例性地,在第一天线端口组包括天线端口1和天线端口3,第二天线端口组包括天线端口2时,部分相干传输码本满足以下(公式4):
其中,j为虚数,上述矩阵公式中的第一行对应天线端口1,第二行对应天线端口2,第三行对应天线端口3,第一列对应第一传输流,第二列对应第二传输流。
在第一天线端口组包括天线端口1和天线端口2,第二天线端口组包括天线端口3时,部分相干传输码本满足以下(公式5):
其中,j为虚数,上述矩阵公式中的第一行对应天线端口1,第二行对应天线端口2,第三行对应天线端口3,第一列对应第一传输流,第二列对应第二传输流。
在第一天线端口组包括天线端口2和天线端口3,第二天线端口组包括天线端口1时,部分相干传输码本满足以下(公式6):
其中,j为虚数,上述矩阵公式中的第一行对应天线端口1,第二行对应天线端口2,第三行对应天线端口3,第一列对应第一传输流,第二列对应第二传输流。
在一些实施例中,对于三个传输流,部分相干传输码本中与第二天线端口组对应传输流的对应位置的码本元素为1,部分相干传输码本中与第一天线端口组相关的码本元素与两个传输流下的两天线端口的全相干传输码本中的码本元素相同。
在上行传输流数为3的情况下,第一节点可以采用第一天线端口组传输两个传输流,采用第二天线端口组传输剩下的一个传输流。因此,第一天线端口组在部分相干传输码本中的对应位置的码本元素,与两天线端口三流的全相干码本的码本元素相同,第二天线端口组在部分相干传输码本中对应传输流的对应位置的码本元素为1,其余位置补0。
示例性地,在第一天线端口组包括天线端口1和天线端口3,第二天线端口组包括天线端口2时,部分相干传输码本满足以下(公式7):
其中,j为虚数,上述矩阵公式中的第一行对应天线端口1,第二行对应天线端口2,第三行对应天线端口3,第一列对应第一传输流,第二列对应第二传输流,第三列对应第三传输流。
在第一天线端口组包括天线端口1和天线端口2,第二天线端口组包括天线端口3时,部分相干传输码本满足以下(公式8):
其中,j为虚数,上述矩阵公式中的第一行对应天线端口1,第二行对应天线端口2,第三行对应天线端口3,第一列对应第一传输流,第二列对应第二传输流,第三列对应第三传输流。
在第一天线端口组包括天线端口2和天线端口3,第二天线端口组包括天线端口1时,部分相干传输码本满足以下(公式9):
其中,j为虚数,上述矩阵公式中的第一行对应天线端口1,第二行对应天线端口2,第三行对应天线端口3,第一列对应第一传输流,第二列对应第二传输流,第三列对应第三传输流。
在一种可能的实现方式中,预编码指示信息可以包括TPMI。TPMI用于指示第一节点用于确定部分相干码本的预编码信息。以下将介绍TPMI表的设计。
在秩的最大值(Maxrank)资源配置为1时,TPMI字段的值如表1所示:
表1
其中,Bit field mapped to index为映射到索引的位字段,layer为层数,该层数和上行传输流数相等,不同的上行传输流数对应不同的TPMI。
在maxrank资源配置为2时,TPMI字段的值如表2所示:
表2

其中,Bit field mapped to index为映射到索引的位字段,layer为层数,该层数和上行传输流数相等,不同的上行传输流数对应不同的TPMI。
在maxrank资源配置为3时,TPMI字段的值如表3所示:
表3
其中,Bit field mapped to index为映射到索引的位字段,layer为层数,该层数和上行传输流数相等,不同的上行传输流数对应不同的TPMI。
在一些实施例中,第一节点可以预先划分好第一天线端口组和第二天线端口组中的天线端口,也可以通过第二节点进行指示。
在第一天线端口组和第二天线端口组为预先划分好的情况下,第一天线端口组和第二天线端口组为预先划分好的;其中,预先划分的第一天线端口组包括第一个发送天线端口和第二个发送天线端口,预先划分的第二天线端口组包括第三个发送天线端口;或者,预先划分的第一天线端口组包括第一个发送天线端口和第三个发送天线端口,预先划分的第二天线端口组包括第二个发送天线端口;或者,预先划分的第一天线端口组包括第二个发送天线端口和第三个发送天线端口,预先划分的第二天线端口组包括第一个发送天线端口。
在第一天线端口组和第二天线端口组的划分为第二节点指示的情况下,第一节点可以接收第一指示信息,第一指示信息用于指示用于划分第一天线端口组和第二天线端口组的划分方式;或者,第一指示信息也可以用于指示第一天线端口组和第二天线端口组分别包括哪些天线端口。
在进行上行传输时,第一节点除了需要基于预编码指示信息确定码本之外,还需要确定在上行传输中哪几个天线端口作为发送天线端口。
需要指出的是,由于第一节点包括多个天线端口,而第一节点在进行上行传输时,需要通过探测参考信号资源指示(SRS Resource Indicator,SRI)字段确定用于上行传输的发送天线端口。然而,相关技术中并不支持适应于三天线端口终端(即支持三个发送天线端口的终端)的SRI的指示,因此,以下将对适应于三天线端口的SRI的指示方式进行介绍。
在一些实施例中,第一节点接收上行传输的控制信息。上行传输的控制信息中探测参考信号资源指示SRI的数量根据第一节点被配置的用于上行传输的SRS资源集的数量以及SRS资源集的内容确定。
在一些实施例中,上行传输的控制信息承载于以下至少之一:RRC信令、DCI。
在一些实施例中,SRI和TPMI可以基于同一个消息下发,例如DCI。
第二节点在接收到SRS之后,可以基于测量到的信道状态确定最优的发送天线端口。之后,第二节点可以向第一节点发送下行传输的控制信息,以指示第一节点确定用于上行传输的发送天线端口。
在一种可能的实现方式中,上行传输的控制信息包括至少一个SRI。每个SRI对应一个SRS资源集,每个SRI用于从SRI对应的SRS资源集中指示上行传输对应的SRS资源。例如,一个SRS资源集中有多个SRS资源,则SRI用于指示这多个SRS资源为确定发送天线端口所需要的SRS资源。之后,第一节点可以基于SRI指示的这个所需要的SRS资源支持的天线端口确定上行传输的发送天线端口。
在又一种可能的实现方式中,在SRS资源配置用于配置的三天线端口SRS资源组包括三个单天线端口SRS资源时,第一节点可以接收一个或多个SRI字段。例如,三个单天线端口SRS资源归属于一个SRS资源集或两个SRS资源集或三个SRS资源集,因此,第二节点发送SRS时,可以通过一个SRI字段指示一个SRS资源集中的三个单天线端口SRS资源,或者两个SRI资源指示两个SRS资源集中的三个单天线端口SRS资源(即一个SRI字段指示一个SRS资源,另一个SRI字段指示两个SRS资源),或者三个SRI字段中一个SRI字段指示一个SRS资源集中的一个SRS资源。这样,第二节点可以通过该SRI字段,向第一节点指示SRS资源,从而可以解决相关技术中,不支持三天线端口终端的场景下,SRI指示方式的问题。
在SRI字段的数量为两个或三个的情况下,两个或三个SRI字段可以指示一个三天线端口SRS资源组,一个SRS资源组对应一个上行传输的所有发送天线端口。或者,两个或三个SRI字段也可以单独的指示多个SRS资源,则可以将上行传输视为三个天线端口的上行传输,而不是通过SRS资源组合支持。然而,在两个或三个SRI字段指示的三个单天线端口SRS资源组共同支持一个上行传输的所有发送天线端口时,应满足以下至少之一:第一节点支持三个发送天线端口、第一节点被2个或3个SRI字段的组合信息所指示(即两个或三个SRI字段共同用于指示上行传输所需要的SRS资源)、当采用两个SRS字段时,两个SRI字段中一个指示一个SRS资源集中的两个单天线端口SRS资源,另一个指示另一个SRS资源集中的一个单天线端口SRS资源,或者,当采用三个SRS字段时,三个SRI字段中一个SRI字段指示一个SRS资源集中的一个SRS资源。
在又一些实施例中,上行传输的控制信息包括的SRI的数量根据第一节点被配置的用于上行传输的SRS资源集的数量以及SRS资源集的配置确定。一个SRI字段用于指示一个SRS资源集中的SRS资源,因此SRI字段的数量与SRS资源集的数量相关。此外,多个SRS资源集中的SRS资源数量为三个时,无需SRI字段指示,因此,SRI的数量与SRS资源集的配置相关。以下,将介绍不同情况下SRI字段的数量。
情况一、配置一个SRS资源集,SRS资源集包括3个以上的单天线端口SRS资源,SRI的数量为1。1个SRI用于指示SRS资源配置用于配置的SRS资源组,SRS资源组由3个单天线端口SRS资源组成。因此,需要通过一个SRI字段指示三个以上的单天线端口SRS资源中的哪三个天线端口SRS资源。
情况二、配置两个SRS资源集,一个SRS资源集包括两个以上的单天线端口SRS资源,另一个SRS资源集包括1个以上的单天线端口SRS资源,SRI的数量为2,每个SRI对应一个SRS资源集。因此,需要通过两个SRI字段来指示两个SRS资源集中的哪三个单天线端口SRS资源。
情况三、配置三个SRS资源集,每个SRS资源集包括1个以上的单天线端口SRS资源,SRI的数量为3,每个SRI对应一个SRS资源集。因此,需要三个SRI字段来指示三个SRS资源集中的哪三个SRS资源(或者哪个SRS资源组)。
情况四、配置一个SRS资源集,SRS资源集包括3个单天线端口SRS资源,SRI被忽略或者数量为0。一个SRS资源集中包括三个单天线端口SRS资源,因此,无需SRI字段指示便可以确定是哪三个单天线端口SRS资源,或者忽略SRI字段。
情况五、配置两个SRS资源集,一个SRS资源集包括两个单天线端口SRS资源,另一个SRS资源集包括一个单天线端口SRS资源,SRI被忽略或者数量为0。两个SRS资源集共同包括三个SRS资源,因此,无需SRI字段指示便可以确定是哪三个单天线端口SRS资源,或者忽略SRI字段。
情况六、配置三个SRS资源集,每个SRS资源集包括1个单天线端口SRS资源,SRI被忽略或者数量为0。三个SRS资源集共同包括三个单天线端口的SRS资源,因此,无需SRI字段指示便可以确定是哪三个单天线端口SRS资源,或者忽略SRI字段。
接下来,第一节点在基于SRI字段确定了用于传输的SRS资源之后,还需要确定该SRS资源关联的第一节点的发送天线端口,是哪几个天线端口。以下将介绍第一节点如何确定上行传输的发送天线端口。
需要指出的是,由于三天线端口的SRS资源(或资源组)支持的天线端口关联第一节点的三个发送天线端口,因此,第一节点在发送SRS时,可以基于不同SRS资源(或资源组)关联的天线端口发送SRS。之后,第二节点基于接收到的SRS确定所有天线端口与第二节点之间的信道状态,从而确定出最优的三个发送天线端口以及预编码指示信息。之后,第二节点可以确定最优的三个发送天线端口发送SRS所使用的SRS资源,并通过SRI字段指示该SRS资源。第一节点接收到SRI字段后,可以确定所指示的SRS资源关联的天线端口为上行传输的发送天线端口。
在一些实施例中,第一节点在接收到SRS资源后,可以确定SRS资源支持的天线端口的索引,并可以通过预先设定好的关联规则确定SRS资源支持的天线端口的索引关联的第一节点的发送天线端口的索引。
在一种可能的实现方式中,对于三天线端口的SRS资源或者三天线端口的SRS资源组,SRS资源或者SRS资源组中的三个天线端口按照发送天线端口的索引顺序与三个发送天线端口关联;或者,SRS资源或者SRS资源组中的三个天线端口按照天线端口组的顺序与三个发送天线端口关联。
示例性地,三天线端口的SRS资源(或资源组)支持的天线端口的索引,按照第一节点的发送天线端口的索引顺序关联,即SRS P_0(即SRS资源支持的第一个端口)关联天线端口P_0(即第一节点的第一个天线端口),SRS P_1关联天线端口P_1,SRS P_2关联天线端口P_2。
又一示例性地,三天线端口的SRS资源(或资源组)支持的天线端口的索引,按照第一节点的天线端口组的顺序进行关联。例如,在第一天线端口组包括天线端口1和天线端口2,第二天线端口组包括天线端口1的情况下,假设第一天线端口组的顺序在第二天线端口组的顺序之前,则SRS P_0关联天线端口P_0,SRS P_1关联天线端口P_2,SRS P_2关联天线端口P_1。
以下将以三种模式的SRS资源,分别介绍这两种关联规则。
第一种SRS资源为丢弃一个天线端口的4天线端口的SRS资源(即4-1模式):
图3示出了一种4-1模式的SRS资源的关联规则图。如图3所示,SRS1为一个四天线端口的SRS资源,其支持的天线端口包括:SRS1 P_0、SRS1 P_1、SRS1 P_2、SRS1 P_3,但是将最后一个天线端口SRS1 P_3进行丢弃(即不使用这个天线端口)。第一节点的用于上行传输(例如,物理上行共享信道(Physical Uplink Shared Channel,PUSCH))的天线端口包括:P_0、P_1、P_2。
在按照第一节点的天线端口的顺序进行关联的情况下,SRS1 P_0关联天线端口P_0、SRS1 P_1关联天线端口P_1、SRS1 P_2关联天线端口P_2。或者,在按照天线端口组的顺序进行关联,且第一天线端口组(包括天线端口P_0、天线端口P_2)的顺序在第二天线端口组(包括天线端口P_1)之前的情况下,SRS1 P_0关联天线端口P_0、SRS1 P_1关联天线端口P_2、SRS1 P_2关联天线端口P_1。
第二种SRS资源为两个SRS资源,其中,一个SRS资源支持的天线端口数为2个,另一个SRS资源支持的天线端口数为1个(即2+1模式):
图4示出了一种2+1模式的SRS资源的关联规则图。如图4所示,SRS1为一个双天线端口的SRS资源,其支持的天线端口为:SRS1 P_0、SRS1 P_1,SRS2为一个单天线端口的SRS资源,其支持的天线端口为SRS2 P_0。第一节点的用于上行传输(PUSCH)的天线端口包括:P_0、P_1、P_2。两个SRS资源组合起来支持第一节点的三个天线端口P_0、P_1、P_2,而这三个天线端口为用于PUSCH的三个发送天线端口。
在按照第一节点的天线端口的顺序进行关联的情况下,SRS1 P_0关联天线端口P_0、SRS1 P_1关联天线端口P_1、SRS2 P_0关联天线端口P_2。或者,在按照天线端口组的顺序进行关联,且第一天线端口组(包括天线端口P_0、天线端口P_2)的顺序在第二天线端口组(包括天线端口P_1)之前的情况下,SRS1 P_0关联天线端口P_0、SRS1 P_1关联天线端口P_2、SRS2 P_0关联天线端口P_1。
第三种SRS资源为三个单天线端口SRS资源(即1+1+1模式):
图5示出了一种1+1+1模式的SRS资源的关联规则图。如图5所示,SRS1、SRS2、SRS3为三个单天线端口的SRS资源,其支持的天线端口分别为:SRS1 P_0、SRS2 P_0、SRS3 P_0。第一节点的用于上行传输(PUSCH)的天线端口包括:P_0、P_1、P_2。三个SRS资源组合起来支持第一节点的三个天线端口P_0、P_1、P_2,而这三个天线端口为用于PUSCH的三个发送天线端口。
在按照第一节点的天线端口的顺序进行关联的情况下,SRS1 P_0关联天线端口P_0、SRS2 P_0关联天线端口P_1、SRS3 P_0关联天线端口P_2。或者,在按照天线端口组的顺序进行关联,且第一天线端口组(包括天线端口P_0、天线端口P_2)的顺序在第二天线端口组(包括天线端口P_1)之前的情况下,SRS1 P_0关联天线端口P_0、SRS2 P_0关联天线端口P_2、SRS3 P_0关联天线端口P_1。
本公开实施例提供的探测参考信号资源配置方法可以应用于图1所示的通信系统中的第二节点102。图6示出了一种探测参考信号资源配置的流程示意图二,如图6所示,该探测参考信号资源配置方法包括以下S601和S602。
S601、向第一节点发送SRS资源配置。
其中,SRS资源配置至少用于配置一个SRS资源组或者一个SRS资源。例如,第一节点支持三个发送天线端口。SRS资源配置用于配置的一个SRS资源组为三天线端口的SRS资源组,SRS资源配置用于配置的一个SRS资源为三天线端口的SRS资源。
第二节点在为第一节点配置SRS资源时,配置的SRS资源一般都是适合一个发送天线端口、两个发送天线端口或四个发送天线端口的终端,而没有适应于三个天线发送端口的终端。因此,在第一节点支持三个发送天线端口(即三天线端口的终端)的情况下,第一节点可以接收第二节点发送的SRS资源配置,从而可以配置适应于第一节点的三天线端口的SRS资源组或三天线端口的SRS资源,可以解决如何向支持三个发送天线端口的终端配置对应的SRS资源的问题。
S602、接收第一节点基于SRS资源配置发送的SRS。
需要指出的是,第二节点指示SRS资源(或资源组)、指示SRI、指示码本以及SRS资源与天线端口之间的关联规则可以参考第一节点的内容,本公开实施例在此不再赘述。
在一些实施例中,在上述S601之前,第二节点可以接收第一节点上报的天线收发能力。
应理解,第二节点接收天线收发能力的描述可以参考上述第一节点发送天线收发能力的内容,本公开实施例在此不再赘述。
在一些实施例中,在上述S602之后,第二节点可以向第一节点发送预编码指示信息。
应理解,第二节点发送预编码指示信息的描述可以参考上述第一节点接收预编码指示信息的内容,本公开实施例在此不再赘述。
在一种可能的实现方式中,第二节点还可以向第一节点发送第一指示信息。第一指示信息和预编码指示信息可以承载于相同的DCI中,或者,第一指示信息也可以承载于预编码指示信息中。第二节点发送第一指示信息的描述可以参考上述第一节点接收第一指示信息的描述,本公开实施例在此不再赘述。
在一些实施例中,第二节点可以向第一节点发送上行传输的控制信息。例如,上行传输的控制信息可以与预编码指示信息承载于相同的DCI中。第二节点发送上行传输的控制信息的描述可以参考上述第一节点接收上行传输的控制信息的描述,本公开实施例在此不作赘述。
可以理解的是,探测参考信号资源配置装置为了实现上述功能,其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到,结合本公开实施例描述的各示例的算法步骤,本公开能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行,取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能,但是这种实现不应认为超出本公开的范围。
本公开实施例可以根据上述方法实施例对探测参考信号资源配置装置进行功能模块的划分,例如,可以对应每一个功能划分每一个功能模块,也可以将两个或两个以上的功能集成在一个功能模块中。上述集成的模块既可以采用硬件的形式实现,也可以采用软件的形式实现。需要说明的是,本公开实施例中对模块的划分是示意性的,仅仅为一种逻辑功能划分,实际实现时可以有另外的划分方式。下面以采用对应每一个功能划分每一个功能模块为例进行说明。
