这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。为了便于理解，首先介绍本申请涉及的术语。
1、探测参考信号(sounding reference signal，SRS)
在第五代(5th generation，5G)新空口(new radio，NR)系统中，上行SRS可以是周期、半持续或非周期SRS，窄带或宽带，单端口或多端口。上行SRS参数由网络设备向终端设备配置，可以配置包括端口数目、频域资源位置、时域资源位置、序列、序列循环偏移量等参数。
网络设备可以为终端配置多个上行SRS资源集合，一个资源集合包含一个或者多个SRS资源。
2、天线切换
NR系统中支持网络设备通过信道互易获取下行信道信息，以提高下行数据传输性能。为了支持网络设备在各种终端收发能力下都能通过信道互易有效获取下行信息，NR系统特别设计了SRS参考信号，对于不同的天线配置，SRS资源配置情况也各不相同。
例如，对于收发天线数相同(T＝R)终端，gNB可以最多配置两个SRS资源集合，在一个集合中只有一个SRS资源其中端口数等于终端的发送天线数。两个SRS资源集合中一个可以配置为周期，另一个可以配置为非周期。而对于一发两收(1T2R)能力的终端，gNB可以最多配置两个SRS资源集合，在一个集合中有两个SRS资源、每个SRS资源仅有一个端口。

下面结合附图对本申请所提供的一种天线切换能力上报方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种天线切换能力上报方法的流程示意图。如图2所示，该方法由终端设备执行，可以包括但不限于如下步骤：
步骤S21，向网络设备上报天线切换能力的指示信息，其中，指示信息用于指示终端设备支持最大8个发送天线Tx的天线切换配置。
终端设备的收发能力可以分为收发天线数目相同(T＝R)以及收天线多于发天线(R>T)。在终端设备支持8Tx时，终端设备可以包括以下收发能力：
例如，收发天线数目相同主要有一发一收(1T1R)、两发两收(2T2R)、四发四收(4T4R)、八 发八收(8T8R)。再例如，收天线多于发天线主要有一发两收(1T2R)、一发四收(1T4R)、两发四收(2T4R)、四发八收(4T8R)等。
本申请实施例中，终端设备可以包括8个Tx，因此，终端设备的天线切换配置可以基于8Tx进行扩展定义。例如，终端设备的天线切换配置还可以包括8T8R。为了适用不同的业务或者场景，终端设备的天线配置可以在目前的天线切换配置和扩展的天线切换配置中进行切换。
对于不同的天线切换配置对应有不同的天线切换能力，相应地网络设备为不同的天线切换能力下的终端设备配置的SRS资源也不相同，因此网络设备需要基于终端设备上报的能力，在能力范围内为上报的天线切换能力配置合适的SRS资源。本实施例中，终端设备向网络设备发送指示信息，指示信息可以指示终端设备支持的天线切换配置，其中天线切换配置包括终端设备能够支持的多种收发能力，这样可以使得网络设备获知终端设备所能够支持的多种收发能力，进而根据终端设备所能够支持的多种收发能力为终端设备配置一个或多个相应的SRS资源。其中，SRS资源可以用于获取下行信道状态信息(Channel State Information，CSI)，进而获取信道质量。
需要说明的是，针对支持上行8Tx的终端设备，本实施例中可以增加相关的8Tx的天线配置，对天线切换配置进行扩展，例如可以包括8T8R，并基于指示信息指示给网络设备，从而可以使得网络设备增强相应的SRS资源配置。
可选地，可以定义新的天线切换配置8T8R，则指示信息中包括新增的天线切换配置8T8R。在另一些实现中，指示信息还可以包括针对Tx进行天线切换时对应的天线切换配置的组合信息。在又一些实现中，指示信息还可以包括针对Tx/Rx进行天线切换时对应的天线切换配置的组合信息。需要说明的是，指示信息中可以包括上述指示内容的一个或多个，上述指示内容可以单独上报给网络设备，也可以联合上报给网络设备。
可选地，终端设备可以将指示信息通过无线资源控制(Radio Resource Control，RRC)信令或者其他高层信令上报给网络设备，本申请实施例中此处不仅限定。
在一些实现中，终端设备支持最大8Tx且同时支持包括6Tx的天线切换配置，则指示信息中可以包括6Tx对应的天线切换配置。在另一些实现中，终端设备支持最大8Tx但不支持包括6Tx的天线切换配置，则指示信息中可以不包括6Tx对应的天线切换配置。
本申请实施例提供一种天线切换能力上报方法，解决了在终端设备的上行增强至8个发送天线时如何上报切换能力的问题，为终端设备支持8Tx定义了新的上报方式，通过向网络设备上报天线切换能力的指示信息，可以使网络设备根据上报终端设备支持8Tx的天线切换能力，为终端设备配置适合的SRS资源。

指示信息中包括以下信息中的至少一项：新增的天线切换配置、发送天线切换时对应的第一天线切换配置集合、发送/接收天线切换时对应的第二天线切换配置集合。
由于本实施例中的终端设备支持8Tx，且受限于终端设备硬件限制，终端设备的接收天线(Rx)应大于等于发送天线(Tx)，则新增的天线切换配置包括8T8R。
终端设备可以基于业务在所支持的最大能力范围内，对发送天线、发送/接收天线进行切换。终端设备在对发送天线进行切换时可以对应的第一天线切换配置集合包括nT8R的天线切换配置，其中，n为小 于或等于8的正整数。基于8T8R对发送/接收天线进行切换时，发送/接收天线切换时对应的第二天线切换配置集合包括mTkR的天线切换配置，其中，m和k均为小于或者等于8的正整数。
例如，第一天线切换配置可以包括1T8R、2T8R、4T8R等。
例如，第二天线切换配置可以包括1T1R、1T2R、1T4R、1T6R、2T2R、2T4R、2T6R、4T4R等。
步骤S32，向网络设备上报天线切换能力的指示信息。
终端设备通过指示信息向网络设备上报天线切换能力，以使网络设备可以根据终端设备所能够支持的多种收发能力为终端配置一个或多个相应的SRS资源。
在一些实现中，终端设备将支持的天线切换配置直接发送给网络设备。
