请参见图2，图2为本公开的实施例提供的一种参考信号的发送方法的流程图，该方法由网络侧设备执行。如图2所示，该参考信号的发送方法可以包括但不限于以下步骤。
步骤S201：确定参考信号配置信息。
其中，本公开中的参考信号配置信息可理解为网络侧设备配置的参考信号的配置信息，该配置信息可用以表征网络侧设备配置的参考信号的波束信息。例如，网络侧设备可以配置参考信号，其中配置的参考信号可以用集合来表示，该参考信号集合中可以有一个或多个网络侧设备配置的参考信号，在网络侧设备完成参考信号的配置后，可以确定参考信号配置信息。
其中，在本公开的一些实施例中，参考信号配置信息至少包括以下至少一项：配置的参考信号集合之中每个参考信号的索引；配置的基准参考信号的索引；配置的参考信号集合之中每个参考信号的波束宽度；配置的参考信号集合之中相邻索引的参考信号的发送波束之间的间隔角度。
在一种实现方式中，每个参考信号的索引可以分别用1个索引值表示，比如用i表示；或者，每个参考信号的索引可以分别用2个分量索引值表示，比如使用(m,n)表示。
在一种实现方式中，配置的基准参考信号的索引可以使用1个索引值表示，比如用i 0表示；或者，配置的基准参考信号的索引可以用2个分量索引值表示，比如使用(m 0,n 0)表示。
在一种实现方式中，该波束宽度可理解为两个波束边界之间的夹角。其中，每个参考信号的波束宽度可理解为两个相邻索引的参考信号的发送波束的波束边界之间的夹角。其中，在本公开的实施例中，波束边界定义为：相对于对应波束最强能量方向衰减预设分贝(例如：3dB)的波束方向。
在一种实现方式中，以相邻索引的两个参考信号对应的两个发送波束为波束1及波束2为例，则相邻索引的参考信号的发送波束之间的间隔角度可以是相邻波束中波束1的左边界与波束2右边界间的角度，或者还可以是波束1的右边界与波束2的左边界间的角度，或者，还可以是波束1的左边界间与波束2的左边界的角度，或者，还可以是波束1的右边界与波束2的右边界间的角度，可根据实际应用决定。
在一种可选地实现方式中，该间隔角度可包括第一维的间隔角度和/或第二维的间隔角度。可以理解，当参考信号的发送波束为第一维波束时，则该间隔角度为第一维的间隔角度；当参考信号的发送波束为第二维波束时，则该间隔角度为第二维的间隔角度；当参考信号的发送波束为二维波束时，则该间隔角度包括第一维的间隔角度和第二维的间隔角度。
其中，第一维的间隔角度可以为第一维波束中心的间隔角度，第二维的间隔角度可以为第二维波束中心的间隔角度；或者，第一维的间隔角度可以为第一维波束边界的间隔角度，第二维的间隔角度可以为第二维波束边界的间隔角度。
也就是说，该间隔角度的确定方式可以包括以下两种方式：方式1，波束中心的间隔角度，即波束能量最强的方向的间隔角度；方式2，波束边界的间隔角度。
需要说明的是，在本公开的实施例中，第一维指水平维度或者垂直维度，第二维指水平维度和垂直维度中与第一维度不同的另一维度。例如，第一维可以为水平维度，第二维可以为垂直维度。又如，第一维可以为垂直维度，第二维可以为水平维度。
步骤S202：发送参考信号配置信息，该参考信号配置信息用于指示参考信号的方向信息。
步骤S203：基于参考信号配置信息发送相应的参考信号。
其中，在本公开的一些实施例中，该相应的参考信号用于指示终端设备进行波束测量和/或波束管理。
举例而言，网络侧设备基于参考信号配置信息，使用对应的发送波束向终端设备发送相应的参考信号。终端设备可以接收上述网络侧设备发送的参考信号配置信息，并根据该参考信号配置信息和/或参考信号索引的配置方式，确定网络侧设备配置的参考信号的方向信息，进而基于该方向信息接收相应的参考信号，以便基于接收到的参考信号完成波束测量和/或波束管理。作为一种示例，终端设备可以利用接收到的参考信号完成基于AI(Artificial Intelligence，人工智能)/ML(Machine Learning，机器学习)的波束预测、波束管理和上报。
在一种实现方式中，网络侧设备可以在向终端设备发送的参考信号配置信息中包含的参考信号的方向上，向终端设备发送相应的参考信号，该参考信号用于指示终端设备进行波束测量。
在一种实现方式中，网络侧设备可以在向终端设备发送的参考信号配置信息中包含的参考信号的方向上，向终端设备发送相应的参考信号，该参考信号用于指示终端设备进行波束管理。
在一种实现方式中，网络侧设备可以在向终端设备发送的参考信号配置信息中包含的参考信号的方向上，向终端设备发送相应的参考信号，该参考信号用于指示终端设备进行波束测量和波束管理。
通过实施本公开的实施例，可以确定参考信号配置信息，并将该配置信息发送至终端设备，以使终端设备基于该配置信息确定网络侧设备配置的参考信号的方向信息，使得终端设备基于该方向接收相应的参考信号，以便基于该参考信号完成波束测量和/或波束管理。由此可见，本公开通过向终端设备发送参考信号的波束信息，能够辅助终端设备更好地进行波束测量、波束预测及波束管理，从而可以提升终端设备波束测量及波束管理的能力，从而可以实现对窄波束的精确对准和实时跟踪更新。
需要说明的是，本公开中的参考信号配置信息是网络侧设备配置参考信号后确定的配置信息。其中，该参考信号配置信息中每个参考信号的索引可以基于参考信号索引的配置方式来确定。也就是说，本公开可以基于参考信号索引的配置方式来确定网络侧设备配置的参考信号集合之中每个参考信号的索引。可以理解，由于参考信号的发送波束可能为一维波束，或者还有可能为二维波束，即参考信号的发送波束的维度的不同，导致参考信号索引的配置方式也可能会有所不同。下面将结合图3至图5从参考信号的发送波束的不同维度，分别介绍确定参考信号配置信息之中每个参考信号的索引的实现方式。
在本公开的一些实施例中，请参见图3，图3为本公开的实施例提供的一种确定配置的参考信号集合之中每个参考信号的索引的方法的流程图。当参考信号集合中参考信号的波束为一维波束时，且该发送波束为第一维(如水平维度)波束时，可采用该方法确定配置的参考信号集合之中每个参考信号的索引。如图3所示，该确定配置的参考信号集合之中每个参考信号的索引的方法可以包括但不限于以下步骤。
步骤S301：以基准方向为起始方向，以第一维的间隔角度为步长，在第一维上按照正方向或负方向依次确定配置的参考信号集合之中每个参考信号的第一维的分量索引值。
在本公开的实施例中，该第一维的间隔角度可以为第一维波束中心的间隔角度；或者，该第一维的间隔角度可以为第一维波束边界的间隔角度。
举例而言，以该第一维的间隔角度为第一维波束中心的间隔角度为例，可以基准方向为起始方向，以第一维波束中心的间隔角度为步长，在第一维上按照规定的正方向或负方向，经m个步长后到达某一参考信号的预设位置(例如，该参考信号波束能量最强的方向)，则m即为该参考信号的第一维的分量索引值，且m的最大值为360°除以第一维的间隔角度所得的值。
需要说明的是，随着旋转方向的不同，索引值大小变化也会不同。在本公开的一些实施例中，可以预先设置索引值随旋转方向的大小变化规律，例如：可以预先设置按正方向旋转时，索引值逐渐变大，按负正方向旋转，索引值逐渐变小；或者，可以预先设置按正方向旋转时，索引值逐渐变小，按负正方向旋转，索引值逐渐变大。可以根据实际应用来决定该索引值随旋转方向的大小变化规律，对此本公开不做具体限定。
作为一种示例，以按正方向旋转时，索引值逐渐变大，按负正方向旋转，索引值逐渐变小为例，确定网络侧设备配置的参考信号集合中参考信号的个数为10个，则配置的参考信号的索引个数也应为10个，以第一个索引序号为0为例，假设以基准方向为起始方向，以第一维波束中心的间隔角度为步长，在第一维上正方向旋转2个步长后到达一个参考信号，则该参考信号的索引值为2；在负方向旋转2个步长后到达另一个参考信号，则该参考信号的索引值为8。
作为另一种示例，以按正方向旋转时，索引值逐渐变小，按负正方向旋转，索引值逐渐变大为例，确定网络侧设备配置的参考信号集合中参考信号的个数为10个，则配置的参考信号的索引个数也应为 10个，以第一个索引序号为0为例，假设以基准方向为起始方向，以第一维波束中心的间隔角度为步长，在第一维上正方向旋转2个步长后到达一个参考信号，则该参考信号的索引值为8；在负方向旋转2个步长后到达另一个参考信号，则该参考信号的索引值为2。
在一种可选地实现方式中，该基准方向可以为配置的基准参考信号的波束方向；或者，基准方向可以为预设的绝对方向。
举例而言，可以将网络侧设备配置的基准参考信号的波束方向作为基准方向，或者，可以预先设置一个绝对方向作为基准方向；例如：将水平维度的正北方向设置为该基准方向，将垂直维度的天顶方向设置为该基准方向。
步骤S302：根据每个参考信号的第一维的分量索引值确定配置的参考信号集合之中每个参考信号的索引。
在一种可选地实现方式中，根据每个参考信号的第一维的分量索引值确定配置的参考信号集合之中每个参考信号的索引，包括：将每个参考信号的第一维的分量索引值作为每个参考信号的索引。
举例而言，可将每个参考信号的第一维的分量索引值直接作为对应的参考信号的索引。
通过实施本公开的实施例，在参考信号集合中参考信号的发送波束为一维波束时，且该发送波束为第一维(如水平维度)波束时，可以以基准方向为起始方向，以第一维的间隔角度为步长，在第一维上按照正方向或负方向依次确定配置的参考信号集合之中每个参考信号的第一维的分量索引值，从而可以实现配置的参考信号的索引。
在本公开的一些实施例中，请参见图4，图4为本公开的实施例提供的另一种确定配置的参考信号集合之中每个参考信号的索引的方法的流程图。当参考信号集合中参考信号的波束为一维波束时，且该发送波束为第二维(如垂直维度)波束时，可采用该方法确定配置的参考信号集合之中每个参考信号的索引。如图4所示，该确定配置的参考信号集合之中每个参考信号的索引的方法可以包括但不限于以下步骤。

需要说明的是，随着旋转方向的不同，索引值大小变化也会不同。在本公开的一些实施例中，可以预先设置索引值随旋转方向的大小变化规律，例如：可以预先设置按正方向旋转时，索引值逐渐变大，按负正方向旋转，索引值逐渐变小；或者，可以预先设置按正方向旋转时，索引值逐渐变小，按负正方向旋转，索引值逐渐变大。可以根据实际应用来决定该索引值随旋转方向的大小变化规律，对此本公开不做具体限定。其中，参考信号的第二维的分量索引值的实现方式，与上述图3所示实施例中参考信号的第一维的分量索引值的实现方式类似，可参照上述图3所示实施例中参考信号的第一维的分量索引值的实现方式的描述，在此不再赘述。
在一种可选地实现方式中，该基准方向可以为配置的基准参考信号的波束方向；或者，基准方向可以为预设的绝对方向。
举例而言，可以将网络侧设备配置的基准参考信号的波束方向作为基准方向，或者，可以预先设置一个绝对方向作为基准方向；例如：将水平维度的正北方向设置为该基准方向，将垂直维度的天顶方向设置为该基准方向。
步骤S402：根据每个参考信号的第二维的分量索引值，确定配置的参考信号集合之中每个参考信号的索引。
在一种可选地实现方式中，根据每个参考信号的第二维的分量索引值确定配置的参考信号集合之中每个参考信号的索引，包括：将每个参考信号的第二维的分量索引值作为每个参考信号的索引。

在本公开的一些实施例中，请参见图5，图5为本公开的实施例提供的又一种确定配置的参考信号集合之中每个参考信号的索引的方法的流程图。当参考信号集合中参考信号的波束为二维波束时，可采用该方法确定配置的参考信号集合之中每个参考信号的索引。如图5所示，该确定配置的参考信号集合之中每个参考信号的索引的方法可以包括但不限于以下步骤。
步骤S501：以基准方向为起始方向，以第一维的间隔角度为步长，在第一维上按照正方向或负方向依次确定配置的参考信号集合之中每个参考信号的第一维的分量索引值。
在本公开的实施例中，步骤S501可分别采用本公开的各实施例中的任一种方式实现，本公开的实施例并不对此作出限定，也不再赘述。
步骤S502：以基准方向为起始方向，以第二维的间隔角度为步长，在第二维上按照正方向或负方向依次确定配置的参考信号集合之中每个参考信号的第二维的分量索引值。
在本公开的实施例中，步骤S502可分别采用本公开的各实施例中的任一种方式实现，本公开的实施例并不对此作出限定，也不再赘述。
需要说明的是，在本公开的实施例中，在第一维确定参考信号的第一维的分量索引值按照的方向，和在第二维确定参考信号的第二维的分量索引值按照的方向可以相同也可以不同。
作为一种示例，以第一维的基准方向为起始方向，以第一维的间隔角度为步长，可以在第一维上按照正方向依次确定配置的参考信号集合之中每个参考信号的第一维的分量索引值，并以第二维的基准方向为起始方向，以第二维的间隔角度为步长，在第二维上按照负方向依次确定配置的参考信号集合之中每个参考信号的第二维的分量索引值。

作为一种示例，以第一维的基准方向为起始方向，以第一维的间隔角度为步长，可以在第一维上按照负方向依次确定配置的参考信号集合之中每个参考信号的第一维的分量索引值，并以第二维的基准方向为起始方向，以第二维的间隔角度为步长，在第二维上按照负方向依次确定配置的参考信号集合之中每个参考信号的第二维的分量索引值。
作为另一种示例，以第一维的基准方向为起始方向，以第一维的间隔角度为步长，可以在第一维上按照负方向依次确定配置的参考信号集合之中每个参考信号的第一维的分量索引值，并以第二维的基准方向为起始方向，以第二维的间隔角度为步长，在第二维上按照正方向依次确定配置的参考信号集合之中每个参考信号的第二维的分量索引值。
步骤S503：根据每个参考信号的第一维的分量索引值和每个参考信号的第二维的分量索引值，确定配置的参考信号集合之中每个参考信号的索引。
在一种可选地实现方式中，可以将每个参考信号的第一维的分量索引值和每个参考信号的第二维的分量索引值，作为每个参考信号的索引；或者，可以根据每个参考信号的第一维的分量索引值和每个参考信号的第二维的分量索引值，生成每个参考信号的索引。
举例而言，以参考信号的索引以两个分量索引值表示为例，可将每个参考信号的第一维的分量索引值和每个参考信号的第二维的分量索引值直接作为对应的每个参考信号的索引。例如，以某个参考信号的第一维的分量索引值为m，该参考信号的第二维的分量索引值为n为例，可将该参考信号的第一维的分量索引值和该参考信号的第二维的分量索引值直接作为该参考信号的索引的两个分量，即该参考信号的索引为(m,n)，即用两个分量索引值表示。
又如，以参考信号的索引以一个索引值表示为例，可以根据每个参考信号的第一维的分量索引值和每个参考信号的第二维的分量索引值，使用预设的生成函数，生成每个参考信号的索引。
在一种实现方式中，可以根据每个参考信号的第一维的分量索引值、第一维的波束数目、以及每个参考信号的第二维的分量索引值，生成每个参考信号的索引；或者，根据每个参考信号的第一维的分量索引值、每个参考信号的第二维的分量索引值以及第二维的波束数目，生成每个参考信号的索引。
作为一种示例，根据每个参考信号的第一维的分量索引值、第一维的波束数目、以及每个参考信号的第二维的分量索引值，生成每个参考信号的索引所用的生成函数的公式可表示如下：
i＝m+nM
其中，i为参考信号的索引，m为每个参考信号的第一维的分量索引值，M为第一维的波束数目，n为每个参考信号的第二维的分量索引值，作为一种示例，m和n分别可以从索引序号0开始。
作为另一种示例，根据每个参考信号的第一维的分量索引值、每个参考信号的第二维的分量索引 值以及第二维的波束数目，生成每个参考信号的索引所用的生成函数的公式可表示如下：
i＝mN+n
其中，i为参考信号的索引，m为每个参考信号的第一维的分量索引值，M为第一维的波束数目，n为每个参考信号的第二维的分量索引值，作为一种示例，m和n分别可以从索引序号0开始。
通过实施本公开的实施例，在参考信号集合中参考信号的发送波束为二维波束时，可以分别以第一维及第二维的基准方向为起始方向，以对应的第一维及第二维的间隔角度为步长，在第一维及第二维上按照正方向或负方向依次确定配置的参考信号集合之中每个参考信号的第一维及第二维的分量索引值，从而可以实现配置的参考信号的索引。
在本公开的一些实施例中，该参考信号的发送方法还可包括：确定参考信号索引的配置方式，该参考信号索引的配置方式为配置每个参考信号的索引时所采用的配置方式；其中，该参考信号配置信息还可包括参考信号索引的配置方式。
可以理解，本公开中的参考信号索引的配置方式可以是协议约定的，或者，该参考信号索引的配置方式该可以是预先设置的。在本公开的实施例中，在参考信号索引的配置方式为由协议约定的时，网络侧设备可以基于协议约定的该配置方式来确定每个参考信号的索引，并在向终端设备发送参考信号配置信息时，无需将该参考信号索引的配置方式发送给终端设备，终端设备在接收到该参考信号配置信息后，基于协议约定的参考信号索引的配置方式即可进行相应处理。在参考信号索引的配置方式为预先设置的时，网络侧设备还需要发送该参考信号索引的配置方式发送给终端设备。例如，网络侧设备向终端设备发送的参考信号配置信息中，还可以包括配置每个参考信号的索引时所采用的配置方式。
请参见图6，图6为本公开的实施例提供的一种参考信号的接收方法的流程图，该方法由终端设备执行。如图6所示，该参考信号的接收方法可以包括但不限于以下步骤。
步骤S601：接收参考信号配置信息；该参考信号配置信息用于指示参考信号的方向信息。
其中，在本公开的一些实施例中，参考信号配置信息可以是由网络侧设备发送的。
其中，在本公开的一些实施例中，参考信号配置信息至少包括以下至少一项：配置的参考信号集合之中每个参考信号的索引；配置的基准参考信号的索引；配置的参考信号集合之中每个参考信号的波束宽度；配置的参考信号集合之中相邻索引的参考信号的发送波束之间的间隔角度。
在一种实现方式中，每个参考信号的索引可以分别用1个索引值表示，比如用i表示；或者，每个参考信号的索引可以分别用2个分量索引值表示，比如使用(m,n)表示。
在一种实现方式中，配置的基准参考信号的索引可以使用1个索引值表示，比如用i 0表示或者，配置的基准参考信号的索引可以用2个分量索引值表示，比如使用(m 0,n 0)表示。
在一种实现方式中，该波束宽度可理解为两个波束边界之间的夹角。其中，每个参考信号的波束宽度可理解为两个相邻索引的参考信号的发送波束的波束边界之间的夹角Δ。
在一种可选地实现方式中，该间隔角度可包括第一维的间隔角度和/或第二维的间隔角度。可以理解，当参考信号的波束为第一维波束时，则该间隔角度为第一维的间隔角度；当参考信号的波束为第二维波束时，则该间隔角度为第二维的间隔角度；当参考信号的波束为二维波束时，则该间隔角度包括第一维的间隔角度和第二维的间隔角度。
其中，第一维的间隔角度可以为第一维波束中心的间隔角度，第二维的间隔角度可以为第二维波束中心的间隔角度；或者，第一维的间隔角度可以为第一维波束边界的间隔角度，第二维的间隔角度可以为第二维波束边界的间隔角度。
也就是说，该间隔角度的确定方式可以包括以下两种方式：方式1，波束中心的间隔角度，即波束能量最强的方向的间隔角度；方式2，波束边界的间隔角度。
步骤S602：根据参考信号配置信息和参考信号索引的配置方式，确定参考信号的方向信息。
举例而言，可以基于接收到的参考信号配置信息和参考信号索引的配置方式，确定网络侧设备配置的参考信号的各个维的分量索引值，基于参考信号各个分量索引值与对应的对间隔角度，即可得到该参考信号的最强能量方向和/或波束宽度。
作为一种示例，以参考信号的发送波束为一维波束为例，假设该参考信号的索引值为2，间隔角度为10°，则该参考信号波束能量最强的方向即为以基准方向为起始角度，在规定的索引值增大的方向偏移2×10°＝20°的方向。
作为另一种示例，以参考信号的发送波束为二维波束为例，假设该参考信号的索引值为(2,3)，间隔角度为10°(如第一维波束中心的间隔角度)及15°(如第二维波束中心的间隔)，则该参考信号在第一维的波束能量最强的方向为以第一维的基准方向为起始角度，在规定的第一维索引值增大的 方向偏移2×10°＝20°的方向；该参考信号在第二维的波束能量最强的方向为以第二维的基准方向为起始角度，在规定的第二维索引值增大的方向偏移3×15°＝45°的方向。
在一种实现方式中，参考信号索引的配置方式为由协议约定的配置方式；或者，参考信号索引的配置方式包含于接收的参考信号配置信息中。
可以理解，本公开的实施例中的参考信号索引的配置方式可以是协议约定的，或者，该参考信号索引的配置方式该可以是预先设置的。在本公开的实施例中，在参考信号索引的配置方式为由协议约定的时，终端设备可以基于协议约定的该配置方式来确定每个参考信号的索引，并在接收网络侧设备发送的参考信号配置信息时，基于协议约定的参考信号索引的配置方式进行相应处理。在参考信号索引的配置方式为预先设置的时，终端设备需要从接收的参考信号配置信息中确定该参考信号索引的配置方式，即配置每个参考信号的索引时所采用的配置方式。
步骤S603：基于配置的参考信号的方向信息，接收相应的参考信号。
其中，相应的参考信号用于指示终端设备进行波束测量和/或波束管理。
举例而言，基于配置的参考信号的方向信息，在该方向信息对应的角度方向上，接收参考信号。作为一种示例，终端设备可以利用接收到的参考信号完成基于AI/ML的波束预测、波束管理和上报。
其中，在本公开的实施例中，参考信号可以是由发送参考信号配置信息的网络侧设备发送的，或者，也可以由其它设备(例如，另一网络侧设备)发送。
作为一种示例，终端设备可接收由网络侧设备A发送的参考信号配置信息，并基于该参考信号配置信息，在对应的角度方向上接收网络侧设备B发送的参考信号。
通过实施本公开的实施例，终端设备可以接收网络侧设备发送的参考信号配置信息，基于该配置信息确定网络侧设备配置的参考信号的方向信息，并基于该方向接收相应的参考信号，以便基于该参考信号完成波束测量和/或波束管理。由此可见，本公开中的终端设备可以基于接收的参考信号配置信息确定网络侧设备配置的参考信号的波束信息，从而可以更好地进行波束测量、波束预测及波束管理，从而可以提升终端设备波束测量及波束管理的能力，从而可以实现对窄波束的精确对准和实时跟踪更新。
