具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例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。
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。“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本公开中，“示例性的”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“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
如背景技术所述，终端的天线收发能力不匹配，终端能够同时接收参考信号的数量高于能够同时发送参考信号的数量，也即终端需要多次发送参考信号才能使得基站能够获取完整的信道信息。
示例性的，如图1所示，以终端每次只能使用1根发射天线发送参考信号，能够使用8根接收天线接收参考信号为例，上述终端的配置也被描述为1发8收、1T8R等。图1所示的终端，具有8根发送天线，8根接收天线，1个发送射频通道，8个接收射频频道。意味着终端每次只能使用1根发送天线发送参考信号，若使基站获取到完整的信道信息，需要终端使用不同的发送天线发送8次参考信号，在上述传输参考的流程中，资源开销较大，传输效率较低。
基于此，本公开实施例提供了一种通信方法，在该通信方法中，第一节点向第二节点发送第一参考信号的配置信息，以使得第二节点基于第一参考信号的配置信息传输第一参考信号。其中，在上述配置信息中，包括第一参考信号的天线描述信息，天线描述信息用于指示第二节点的天线和用于传输第一参考信号的天线的映射关系。基于上述映射关系，第二节点可选择用于传输第一参考信号的天线。相较于相关技术中第二节点使用全部的天线传输第一参考信号，本公开实施例能够降低传输第一参考信号的资源开销，并提高了传输第一参考信号的灵活性，以提高第一参考信号的传输效率。
本公开提供的通信方法可以应用于如图2所示的通信系统中，图2示出本 公开实施例提供的一种通信系统的架构示意图。如图2所示，通信系统包括第一节点10和第二节点20。
在无线通信场景下，第一节点10与第二节点20通过无线信道进行通信。例如，第一节点10为基站，第二节点20为终端，基站与终端之间通过无线信道进行通信。又例如，第一节点10为终端，第二节点20为无线路由器，无线路由器与终端通过无线信道进行通信。又例如，第一节点10为第一基站，第二节点20为第二基站，第一基站与第二基站通过无线信道进行通信。又例如，第一节点10为第一终端，第二节点20为第二终端，第一终端与第二终端通过无线信道进行通信。又例如，第一节点10为中继器，第二节点20为基站，基站与中继器通过无线信道进行通信。又例如，第一节点10为终端，第二节点20为中继器，中继器与终端通过无线信道进行通信。又例如，第一节点10为第一中继器，第二节点20为第二中继器，第一中继器与第二中继器通过无线信道进行通信。又例如，第一节点10为基站，第二节点20为卫星，卫星与基站通过无线信道进行通信。又例如，第一节点10为卫星，第二节点20为基站，基站与卫星通过无线信道进行通信。又例如，第一节点10为终端，第二节点20为卫星，卫星与终端通过无线信道进行通信。又例如，第一节点10为卫星，第二节点20为终端，终端与卫星通过无线信道进行通信。又例如，第一节点10为地面设备，第二节点20为飞行器，飞行器与地面设备通过无线信道进行通信。又例如，第一节点10为第一飞行器，第二节点20为第二飞行器，第一飞行器与第二飞行器通过无线信道进行通信。
在本公开实施例中，主要以第一节点10为基站，第二节点20为终端为例进行说明。
在一些实施例中，第一节点10用于为多个终端提供无线接入服务。具体来说，一个基站提供一个服务覆盖区域(又可称为小区)。进入该区域的终端可通过无线信号与基站通信，以此来接受基站提供的无线接入服务。
在一些实施例中，第一节点10可以是长期演进(long term evolution，LTE)，长期演进增强(long term evolution advanced，LTE-A)中的基站或演进型基站(evolutional node B，eNB或eNodeB)、5G网络中的基站设备、或者未来通信系统中的基站等，基站可以包括各种宏基站、微基站、家庭基站、无线拉远、可重构智能表面(reconfigurable intelligent surface，RIS)、路由器、无线保真(wireless fidelity，WIFI)设备等各种网络侧设备。
在一些实施例中，第二节点20可以是一种具有无线收发功能的设备，可 以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本公开的实施例对应用场景不做限定。终端有时也可以称为用户，用户设备(User Equipment，UE)、接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等，本公开实施例对此并不限定。

本公开的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的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。
图3示出了本公开提供的一种通信方法的流程示意图，如图3所示，该通信方法应用于第一节点，包括以下步骤：
S101、生成第一参考信号的配置信息。
在一些实施例中，在第一节点需要获取与第二节点之间的信道信息的情况下，开始生成第一参考信号的配置信息。
应理解，第一节点与第二节点之间信道的信道信息基于第二节点传输的第一参考信号确定，而在本公开实施例中，第二节点需基于第一参考信号的配置信息传输第一参考信号。因此，在第一节点需要获取与第二节点之间的信道的信息时，开始生成第一参考信号的配置信息，以使得第二节点基于第一参考信号的配置信息，传输第一参考信号，进一步使得第一节点基于第一参考信号，获取与第二节点之间的信道信息。
在一些实施例中，第一节点接收第二节点发送的第二节点的天线配置信息， 以根据天线配置信息生成第一参考信号的配置信息。
其中，天线配置信息包括以下至少一项：天线的实现方式、天线的位置信息、天线的拓扑结构、天线的材料。
在一些实施例中，配置信息包括第一参考信号的天线描述信息。天线描述信息用于指示第二节点的N个天线和第二节点用于传输第一参考信号的X个天线的映射关系；N大于或等于2，且N为正整数；X小于或等于N，且X为正整数。
示例性的，以图1所示的终端为第二节点为例，第二节点的N个天线，即为图1中终端的8个发送天线，第二节点用于传输第一参考信号的X个天线，即为图1中终端在传输第一参考信号时实际使用的天线。
在一些实施例中，第一节点接收第二节点发送的建议的天线描述信息，以根据建议的天线描述信息生成第一参考信号的天线描述信息。
在一些实施例中，天线描述信息所指示的映射关系可用于配置第二节点在传输第一参考信号时的天线信息。
示例性的，天线描述信息包括第二节点用于传输第一参考信号的天线数目和天线序号。例如，天线描述信息包括第二节点用于传输第一参考信号的天线数目为4，天线序号为发送天线1、发送天线2、发送天线3以及发送天线4。在第二节点接收到第一节点发送的第一参考信号的配置信息后，基于配置信息中第一参考信号的天线描述信息，使用发送天线1、发送天线2、发送天线3以及发送天线4传输第一参考信号。
又一示例性的，以图1所示的终端为第二节点为例，该终端的配置为1收8发，终端在传输第一参考信号时，该终端需要分别在不同时刻使用8个天线传输第一参考信号。在本公开实施例中，若天线描述信息包括终端用于传输第一参考信号的天线数目为4，天线序号为发送天线1、发送天线2、发送天线3以及发送天线4的情况下，终端在传输第一参考信号时，仅需在不同时刻使用上述4个发送天线传输第一参考信号即可。
这样一来，通过向第二节点发送第一参考信号的配置信息，以使得第二节点基于该配置信息传输第一参考信号时，可以使用少量发送天线传输第一参考信号，以降低传输第一参考信号时的资源开销，提高了第一参考信号的传输效率。
在一些实施例中，X个天线中Z个天线在传输第一参考信号时使用的频域资源小于或等于其他X-Z个天线在传输第一参考信号时使用的频域资 源。
示例性的，第一节点可根据第二节点的发送天线对应的频域信道状况，为X个天线中的各个天线分配频域资源。
需要说明的是，本实施例以及下文中实施例中所描述的Z，均具有以下性质：Z小于等于X，且Z为正整数。本公开在下文中不在赘述。
这样一来，可以根据各个天线的传输情况，将有限的频域资源有效的分配给传输第一参考信号的发送天线，能够提高频域资源的利用率，降低传输第一参考信号时的频域资源开销。
在一些实施例中，X个天线中Z个天线在传输第一参考信号时使用的时域资源小于或等于其他X-Z个天线在传输第一参考信号时使用的时域资源。
示例性的，第一节点可根据第二节点的发送天线对应的时域信道状况，为X个天线中各个天线分配时域资源。
这样一来，可以将时域资源合理的分配给传输第一参考信号的发送天线，能够使得第二节点更有效的利用时域资源，可以在相同的时间段内，通过分配时域资源，发送更多的第一参考信号，从而提高了传输第一参考信号的传输效率。
在一些实施例中，X个天线中Z个天线在传输第一参考信号时使用的传输资源小于或等于其他X-Z个天线在传输第一参考信号时使用的传输资源。
其中，传输资源包括频域资源和时域资源。示例性的，第一节点可根据第二节点的发送天线对应的频域信道装置和时域信道状况，为X个天线中各个天线分配传输资源。
这样一来，能够更加全面的提高传输第一参考信号时的传输效率。在频域上，通过灵活的分配频域资源，以提高频域资源的利用率。在时域上，通过合理的分配时域资源，以提高时域资源的利用率。

在一些实施例中，X个天线中至少一个天线传输的第一参考信号的生成方式为第一序列生成方式，至少一个天线传输的第一参考信号的生成方式为第二序列生成方式，第一序列生成方式不同于第二序列生成方式。
其中，第一序列生成方式不同于第二序列生成方式。示例性的，第一序列生成方式可以为伪随机Gold序列生成方式、调频信号chirp序列生成方式。第二序列可以为伪随机Gold序列生成方式、调频信号chirp序列生成方式。
需要说明的是，本公开对于第一参考信号的生成方式并不限定，X个天线中传输的X个第一参考信号至少存在两种生成方式。示例性的，以X为4示例，发送天线1传输的第一参考信号的生成方式可以为第一序列生成方式，发送天线2传输的第一参考信号的生成方式可以为第二序列生成方式，发送天线3传输的第一参考信号的生成方式可以为第三序列生成方式，发送天线4传输的第一参考信号的生成方式可以为第四序列生成方式。第一序列生成方式、第一序列生成方式、第一序列生成方式以及第一序列生成方式均不相同。
这样一来，通过传输不同生成序列的第一参考信号，可以实现多样性传输，进而提高信号的覆盖范围和抗干扰能力。并且，不同生成序列的第一参考信号可以在传输过程中以不同的路径传输，有助于克服多个第一参考信号之间的干扰。
在一些实施例中，在X个天线中Z个天线传输第一参考信号失败的情况下，接收第二节点使用Z个天线重新传输的第一参考信号。这样一来，通过第二节点的Z个天线重新传输第一参考信号，能够提供冗余传输路径，有助于克服初始传输失败的情况，提高第一参考信号的可靠性和鲁棒性。

在一些实施例中，第一参考信号包括探测参考信号。
其中，探测参考信号(sounding reference signal，SRS)用于测量上行信道频域信息，进而根据测量结果，选择性调度频域资源。SRS也可用于测量下行信道，进而根据测量结果，进行下行信道预处理。
在一些实施例中，配置信息还包括以下至少一项：第一参考信号的优先级信息、第一参考信号的资源信息、第一参考信号的序列信息以及第一参考信号的功率信息。

例如，探测参考信号(周期，或半持续，或非周期发送)的传输优先级高于携带信道状态信息的物理上行控制信道的传输优先级，探测参考信号的传输优先级高于只携带调度请求的物理上行控制信道的传输优先级。
又例如，在物理上行数据信道没有携带上行链路控制信息(uplink control information，UCI)的情况下，探测参考信号(周期，或半持续，或非周期发送)的传输优先级在发生时域重叠的OFDM符号上高于物理上行 数据信道的传输优先级。
又例如，在物理上行数据信道携带UCI的情况下，探测参考信号如果与携带UCI的OFDM符号存在重叠，则在上述OFDM符号上，探测参考信号(周期，或半持续，或非周期发送)的优先级低于物理上行数据信道。
又例如，在探测参考信号(周期，或半持续，或非周期发送)与解调参考信号使用的空域滤波器不同(或发送波束不同)的情况下，探测参考信号的传输优先级小于解调参考信号的传输优先级。
又例如，在探测参考信号(周期，或半持续，或非周期发送)与解调参考信号使用的空域滤波器相同(或发送波束相同)的情况下，探测参考信号的传输优先级大于解调参考信号的传输优先级。

在另一些实施例中，在第二节点需要传输第一参考信号的情况下，向第一节点发送配置信息请求，以请求第一节点发送第一参考信号的配置信息。相应的，在第一节点接收到第二节点发送的配置信息请求的情况下，第一节点向第二节点发送第一参考信号的配置信息。
这样一来，通过向第二节点发送第一参考信号的配置信息，以使得第二节点基于第一参考信号的配置信息传输第一参考信号。其中，在上述配置信息中， 包括第一参考信号的天线描述信息，天线描述信息用于指示第二节点的天线和用于传输第一参考信号的天线的映射关系。基于上述映射关系，第二节点可选择用于传输第一参考信号的天线。相较于相关技术中第二节点使用全部的天线传输第一参考信号，本公开实施例能够降低传输第一参考信号的资源开销，并提高了传输第一参考信号的灵活性，以提高第一参考信号的传输效率。

在一些实施例中，X个天线中Z个天线在传输第一参考信号时使用的频域资源小于或等于其他X-Z个天线在传输第一参考信号时使用的频域资源。
示例性的，频域资源可以为子载波。以图6所示的终端为例，若第一节点根据频域信道情况得知发送天线1对应的频域信道较为平坦，则第二节点为发送天线1传输的第一参考信号分配20个子载波，为发送天线3、发送天线5和发送天线7传输的第二参考信号各分配40个子载波，此时，X为4，Z为1。若第一节点根据频域信道情况得知发送天线1和发送天线5对应的频域信道较为平坦，则第二节点为发送天线1和发送天线5传输的第一参考信号各分配20个子载波，为发送天线3和发送天线7传输的第二参考信号各分配40个子载波，此时，X为4，Z为2。
在一些实施例中，X个天线中Z个天线在传输第一参考信号时使用的时域资源小于或等于其他X-Z个天线在传输第一参考信号时使用的时域资源。
示例性的，时域资源可以为OFDM符号。以图6所示的终端为例，若第一节点根据时域信道情况得知发送天线1对应的时域信道较为平坦，则第二节点为发送天线1传输的第一参考信号分配1个OFDM符号，为发送天线3、发送天线5和发送天线7传输的第二参考信号各分配2个OFDM 符号，此时，X为4，Z为1。
若第一节点根据时域信道情况得知发送天线1和发送天线5对应的时域信道较为平坦，则第二节点为发送天线1和发送天线5传输的第一参考信号各分配1个OFDM符号，为发送天线3和发送天线7传输的第二参考信号各分配2个OFDM符号，此时，X为4，Z为2。
在一些实施例中，X个天线中Z个天线在传输第一参考信号时使用的传输资源小于或等于其他X-Z个天线在传输第一参考信号时使用的传输资源。
示例性的，传输资源包括频域资源和时域资源，频域资源可以为子载波，时域资源可以为OFDM符号。以图6所示的终端为例，若第一节点根据信道情况得知发送天线1对应的信道较为平坦，则第二节点为发送天线1传输的第一参考信号分配1个OFDM符号(1个OFDM符号上存在20个子载波)，为发送天线3、发送天线5和发送天线7传输的第二参考信号各分配2个OFDM符号(1个OFDM符号上存在20个子载波)，此时，X为4，Z为1。若第一节点根据信道情况得知发送天线1和发送天线5对应的信道较为平坦，则第二节点为发送天线1和发送天线5传输的第一参考信号各分配1个OFDM符号(1个OFDM符号上存在20个子载波)，为发送天线3和发送天线7传输的第二参考信号各分配2个OFDM符号(1个OFDM符号上存在20个子载波)，此时，X为4，Z为2。
在一些实施例中，X个天线中Z个天线在传输第一参考信号时使用的传输功率小于或等于其他X-Z个天线在传输第一参考信号时使用的传输功率。
示例性的，以图6所示的终端为例，第一节点根据四个发送天线的能力、发送目的以及传输信道，确定发送天线1需要的传输功率较低，因此第二节点为发送天线1分配低于发送天线3、发送天线5和发送天线7的传输功率，此时，X为4，Z为1。
在一些实施例中，X个天线中至少一个天线传输的第一参考信号的生成方式为第一序列生成方式，至少一个天线传输的第一参考信号的生成方式为第二序列生成方式。
其中，第一序列生成方式不同于第二序列生成方式。

在一些实施例中，在X个天线中Z个天线传输第一参考信号失败的情况下，使用Z个天线重新传输第一参考信号。
示例性的，以图6所示的终端为例，第二节点使用发送天线1传输第一参考信号时，因上行OFDM符号被第二节点配置为下行OFDM符号，导致传输失败。使用发送天线3传输第一参考信号时，因上行OFDM符号被其他信道占用，导致传输失败，则第二节点使用发送天线1和发送天线3重新传输第一参考信号，此时，X为4，Z为2。
需要说明的是，是否重新传输第一参考信号，为第二节点根据预设规则确定，该预设规则可以为第二节点确定，或者也可以为第一节点和第二节点协商确定。
在一些实施例中，X个天线中至少一个天线传输第一参考信号时使用第二参考信号计算路径损耗，至少一个天线传输第一参考信号时使用第三参考信号计算路径损耗。
其中，第二参考信号不同于第三参考信号。
示例性的，以图6所示的终端为例，终端不同的发送天线会指向不同位置的基站接收天线，不同发送天线计算路损时，使用的参考信号可以不同。第二参考信号可以为CSI-RS、DM-RS、同步信号以及PRS。第三参考信号可以为CSI-RS、DM-RS、同步信号以及PRS。第二节点使用发送天线1传输第一参考信号时，使用CSI-RS计算路径损耗。使用发送天线3传输第一参考信号时，使用DM-RS计算路径损耗。使用发送天线5传输第一参考信号时，使用同步信号计算路径损耗。使用发送天线7传输第一参考信号时，使用PRS计算路径损耗。
