Description

天线切换配置的切换方法、装置及通信设备 技术领域
本公开涉及无线通信技术领域，尤其涉及一种天线切换配置的切换方法、装置及通信设备。
背景技术
在无线通信系统中，终端设备支持的收发能力为多种，即存在多种终端天线切换能力，目前支持的主要有一发一收(1T1R)、两发两收(2T2R)、四发四收(4T4R)，还有一发两收(1T2R)、一发四收(1T4R)、两发四收(2T4R)。同时终端设备可能上报支持多种天线切换能力，例如t1r1-t1r2,t1r1-t1r2-t1r4,t1r1-t1r2-t2r2-t2r4,t1r1-t1r2-t2r2-t1r4-t2r4。网络设备可以在每个BWP上配置对应一种终端设备天线切换能力的天线切换配置，考虑到为了适用当前业务或者场景，终端设备可能需要改变天线切换配置，例如从2T4R降低为1T4R或者2T2R，或者从2T2R改变为4T4R的情况，这时就需要使用不同的功能为“天线切换”的SRS资源配置用于下行CSI的获取。例如：同一终端设备可以将天线切换配置从两发四收(2T4R)降低至一发四收(1T4R)，也可以将天线切换配置从一发两收(1T2R)提高至一发四收(1T4R)，也就是说，该终端设备可以在自身支持的收发能力下，由网络设备调度进行天线切换配置的改变或者回退，从而适应业务需求。
在终端设备的天线切换配置需要切换的场景下，为了实现终端设备这种天线切换配置切换，相关技术中仅能够通过RRC(Radio Resource Control，无线资源控制)重配，或者，BWP(Bandwidth Part，部分带宽)切换来实现。现有协议只能支持终端设备的天线切换按照BWP来配置而非按照终端设备配置,因此只能通过RRC重配或BWP切换来实现，无法实现在当前工作的BWP上实现天线切换配置的动态切换或者回退，因此在灵活性和复杂度方面有很大问题，无法很好支持天线切换配置的变化。在当前的研究中，考虑终端设备的天线数仍然有进一步增加的需求，标准化增加天线数目到支持最大6天线或者8天线。对于支持到最多8天线的终端设备来说，终端设备可以上报支持的各种不同的天线切换配置，对于这类终端设备这种改变天线切换配置的需求的矛盾会更加强烈。

相关技术中，基于BWP的天线切换配置切换需要改变BWP，即BWP需要随天线切换配置切换而改变，灵活性不佳。RRC重配实现终端设备的天线切换配置切换，实现复杂度又较高。在R17的研究中，考虑到终端设备的天线物理通道存在进一步增加的需求，从而终端设备在支持的天线收发能力下，可采用的天线切换配置也相应增加，需要较为简便灵活的天线切换配置切换方式。
本公开中，提供了网络设备通过基于SRS(Sounding Reference Signal，探测参考信号)资源配置，对终端设备进行天线切换配置切换的方式。从而无需进行RRC重配，或者BWP配置改变，即可实现天线切换配置的切换。
下面参考附图对本公开提供的天线切换配置的切换方法、装置及通信设备进行详细描述。
图1为本公开实施例所提供的一种天线切换配置的切换方法的流程示意图，应用于网络设备。
其中，网络设备可以是基站，该基站可以包括多个为终端设备提供服务的小区。根据具体应用场合不同，基站又可以称为接入点，或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备，或者其它名称。
如图1所示，包括以下步骤：
步骤101，根据当前BWP上终端设备待切换至的目标天线切换配置，向终端设备发送用于激活对应的目标SRS资源配置的指示信息。
其中，目标天线切换配置，是终端设备支持的一个或多个天线切换配置中待切换至的一个天线切换配置。目标SRS资源配置，是对应一个或多个SRS资源集合，每个SRS资源集合包括至少一个SRS资源。SRS资源可以是半持续SRS资源，也可以是非周期SRS资源，本实施例中SRS资源类型不作限定。
网络设备根据终端设备的天线收发能力所支持的收发通道数目，确定该终端设备的一个或多个天线切换配置。下面列举终端设备可能支持的天线切换配置，其中，T表示发送通道数，R表示接收通道数。
R15和R16定义的终端的收发能力，根据天线物理通道，可以分为收发天线数目相同和收天线多于发天线。其中，收发天线数目相同即T＝R，具体包括：一发一收(1T1R)、两发两收(2T2R)、四发四收(4T4R)。终端的收发能力还可以分为收天线多于发天线，即R>T，具体包括：一发两收(1T2R)、一发四收(1T4R)、两发四收(2T4R)。
网络设备配置了该终端设备的天线切换配置与SRS资源配置之间的映射关系。
其中，作为一种可能的实现方式，网络设备对该终端设备的每个天线切换配置，配置了对应的一种SRS资源配置。
或者，作为另一种可能的实现方式，网络设备对该终端设备的至少一个天线切换配置，配置了对应的一种SRS资源配置。这里的一种SRS资源配置，包含了一个或多个SRS资源集合，其中，每个SRS资源集合中包含至少一个SRS资源。目标SRS资源配置，是所配置的至少一个天线切换配置中的一个，或者，是所配置的至少一个天线切换配置中的一个或多个SRS资源集合中的部分SRS资源集合，或者，是所配置的至少一个天线切换配置中的一个或多个SRS资源集合中的至少部分SRS资源。
由于网络设备已配置了该终端设备的天线切换配置与SRS资源配置之间的映射关系，从而在确定终端设备待切换至的目标天线切换配置之后，可以根据这种映射关系，指示终端设备对应的目标SRS资源配置，即向终端设备发送用于激活目标SRS资源配置的指示信息。从而终端设备在接收到指示信息后，根据已知的终端设备的天线切换配置与SRS资源配置之间的映射关系，确定需切换至的目标天线切换配置。
在一些可能的实现方式中，用于激活目标SRS资源配置的指示信息，可以承载于控制信令中。该控制信令可以包括MAC(Medium Access Control，媒体接入控制)层信令，例如MAC-CE(Control Element，控制单元)信令；还可以是DCI(Downlink Control Information，下行控制信息)信令。本实施例中，对于指示信息的具体形式不作限定。
指示信息的具体实现形式存在至少以下几种可能：
作为第一种可能的实现形式，指示信息，是目标SRS资源配置的资源标识(ID)。
作为第二种可能的实现形式，指示信息，是比特位图(Bitmap)，比特位图中使能对应目标SRS资源配置的比特位。
作为第三种可能的实现形式，指示信息，是目标SRS资源配置中SRS资源集合或者SRS资源组合列表对应的码点(Code Point)。其中，SRS资源集合或者SRS资源组合列表与码点之间的对应关系由网络设备配置，并通知终端设备。
本公开实施例的天线切换配置的切换方法，通过网络设备根据当前BWP上终端设备待切换至的目标天线切换配置，向该终端设备发送用于激活对应的目标SRS资源配置的指示信息，从而终端设备接收网络设备发送的目标SRS配置的指示信息之后，根据目标SRS配置的指示信息，在当前BWP上切换至对应的目标天线切换配置。由此，无需进行BWP切换或者RRC重配置过程，即可实现终端设备在当前BWP上的天线切换配置切换，提高了天线切换配置的切换灵活性，降低了切换的复杂度。
本领域内技术人员可以理解的，步骤101的技术方案可以单独被实施，也可以与本公开实施例中任意一个其他的技术方案一起被实施，本公开实施例并不对此作出限定。
图2为本公开实施例所提供的另一种天线切换配置的切换方法的流程示意图，应用于网络设备。
如图2所示，包括以下步骤：
步骤201，在当前BWP上对终端设备支持的一个或多个天线切换配置，确定各天线切换配置对应的一个或多个SRS资源集合。
终端设备支持的天线切换配置可以是一个或多个，网络设备对每个天线切换配置配置对应的一个或多个SRS资源集合，作为该天线切换配置对应的SRS资源配置。
步骤202，向终端设备发送携带第一配置信息的高层信令，其中，第一配置信息，是各天线切换配置对应的SRS资源配置。
其中，第一配置信息指示的是终端设备支持的一个或多个天线切换配置中的每个天线切换配置对应的SRS资源配置。第一配置信息中分别对应不同天线切换配置的各SRS资源配置，可以包括一个或多个SRS资源集合，各SRS资源集合包括至少一个SRS资源。
高层信令，例如可以是RRC信令。通过高层信令，对终端设备支持的每个天线切换配置，配置对应的SRS资源配置。
从而在需要指示终端设备进行天线切换配置的切换时，可以激活待切换至的目标天线切换配置对应的目标SRS资源配置。
在一些场景下，需要激活的目标SRS资源配置包括的SRS资源集合是半持续SRS资源集合，或者，SRS资源是半持续SRS资源，则执行步骤203a至步骤204a。
步骤203a，根据当前BWP上终端设备待切换至的目标天线切换配置，向终端设备发送第一MAC层信令，以激活目标SRS资源配置进行半持续SRS资源集合或半持续SRS资源的发送。
其中，第一MAC层信令，携带目标SRS资源配置的指示信息，用于激活已配置的多个SRS资源配置中的目标SRS资源配置，以使终端设备采用激活的目标SRS资源配置进行半持续SRS资源集合或半持续SRS资源的发送。
进一步地，在步骤203a之后，若需要终止终端设备采用目标天线切换配置，以及停止采用该目标天线切换配置进行半持续SRS资源集合或半持续SRS资源的发送，还需要指示该终端设备对对应的目标SRS资源配置去激活，以停止进行半持续SRS资源集合或半持续SRS资源的发送，具体如步骤204a。
步骤204a，响应于终止终端设备采用目标天线切换配置，向终端设备发送与第一MAC层信令对应的携带指示信息的去激活MAC层信令。
其中，第一MAC层信令对应的去激活MAC层信令携带的指示信息，即前述的目标SRS资源配置的指示信息，该指示信息的具体形式参见其它各实施例中相关部分的描述，本实施例中对此不再赘述。
在另一些场景下，需要激活的目标SRS资源配置包括的SRS资源集合是非周期SRS资源集合，或者，SRS资源是非周期SRS资源，则执行步骤203b。
步骤203b，向终端设备发送DCI信令，以触发目标SRS资源配置进行非周期SRS资源集合或非周期SRS资源的发送。
其中，DCI信令用于触发已配置的多个SRS资源配置中的目标SRS资源配置进行非周期SRS资源集合或非周期SRS资源的发送。
DCI信令中，该指示信息处于目标指示域。
作为一种可能的实现方式，目标指示域，是扩展比特位的SRS资源域。从而可以指示更多种可能的SRS资源配置，例如，可以扩展为3bit，用于支持不同SRS资源配置的指示需求。SRS资源域中不同的数值可以指示不同的非周期性SRS资源触发(periodic SRS-Resource Trigger)。
作为另一种可能的实现方式，目标指示域，是重定义的SRS资源域，即包含的比特位与各天线切换配置对应的SRS资源集有对应关系的SRS资源域。目标指示域通过比特图，确定是否使能对应的SRS资源配置，将使能的SRS资源配置作为目标资源配置。例如：分别配置各比特位对应的天线切换配置，以基于天线切换配置和SRS资源配置之间的关系，间接确定各比特位对应的SRS资源配置。又或者例如，配置各比特位与各SRS资源配置的SRS资源(resource set)的标识(ID)之间的对应关系。目标指示域还可以通过码点，确定是否使能对应的SRS资源配置，将使能的SRS资源配置作为目标资源配置。
本公开实施例的天线切换配置的切换方法，通过根据当前BWP上终端设备待切换至的目标天线切换配置，向该终端设备发送用于激活对应的目标SRS资源配置的指示信息，从而终端设备接收网络设备发送的目标SRS配置的指示信息之后，根据目标SRS配置的指示信息，在当前BWP上切换至对应的目标天线切换配置。由此，无需进行BWP切换或者RRC重配置过程，即可实现终端设备在当前BWP上的天线切换配置切换，提高了天线切换配置的切换灵活性，降低了切换的复杂度。
图3为本公开实施例所提供的另一种天线切换配置的切换方法的流程示意图，应用于网络设备。
如图3所示，包括以下步骤：
步骤301，在当前BWP上对终端设备的参考天线切换配置，确定对应的SRS资源配置，其中，SRS资源配置中包括一个或多个SRS资源集合。
其中，参考天线切换配置，包括网络设备选择的一种天线切换配置，或者，终端设备支持的最高能力对应的最高天线切换配置。
作为一种可能的实现方式，网络设备选择的一种天线切换配置可以是终端设备当前采用的天线切换配置。
作为另一种可能的实现方式，网络设备选择的一种天线切换配置可以是从终端设备支持的天线切换配置中依据设定规则确定的一种天线切换配置，例如在一些场景下，网络设备可以选择终端设备支持的最高能力对应的最高天线切换配置。
基于终端设备的收发能力，根据收天线和发天线的数量，可以确定该终端设备支持的最高能力对应的最高天线切换配置。在一些实现方式中，最高天线切换配置，可以是具有最大收天线数量，或者，可以是具有最大发天线数量的天线切换配置，或者，可以是既具有最大收天线数量也具有最大发天线数量的天线切换配置。
对参考天线切换配置，在当前BWP上配置对应的一个或多个SRS资源集合作为参考天线切换配置对应的一SRS资源配置。
步骤302，向终端设备发送携带第二配置信息的高层信令。
其中，第二配置信息，是参考天线切换配置对应的SRS资源配置，参考天线切换配置对应的SRS资源配置包括一个或多个SRS资源集合，各SRS资源集合包括至少一个SRS资源。
高层信令，例如可以是RRC信令。高层信令预先配置参考天线切换配置对应的SRS资源配置，由于配置的一个SRS资源配置中包括一个或多个SRS资源集合，且各SRS资源集合中包括至少一个SRS资源，后续便可以通过SRS资源配置中动态选择部分SRS资源集合，或者SRS资源作为目标SRS资源配置，从而可以实现对终端设备的天线切换配置的动态切换。也就是说，后续待切换至的目标天线切换配置所对应的目标SRS资源配置，是终端设备的参考天线切换配置所对应的一个或多个SRS资源集合中的至少部分SRS资源。
在一些场景下，需要激活的目标SRS资源配置包括的SRS资源集合是半持续SRS资源集合，或者，SRS资源是半持续SRS资源，则执行步骤303a至步骤304a。
步骤303a，根据当前BWP上终端设备待切换至的目标天线切换配置，向终端设备发送第一MAC层信令，以激活并发送已配置的一个SRS资源配置中属于目标SRS资源配置的至少一个半持续SRS资源集合或半持续SRS资源。
本步骤中，第一MAC层信令，携带目标SRS资源配置的指示信息，用于激活已配置的一个SRS资源配置中的目标SRS资源配置，以使终端设备采用激活的目标SRS资源配置进行半持续SRS资源集合或半持续SRS资源的发送。
进一步地，在步骤303a之后，若需要终止终端设备采用目标天线切换配置，以及停止采用该目标天线切换配置进行半持续SRS资源集合或半持续SRS资源的发送，还需要指示该终端设备对对应的目标SRS资源配置去激活，以停止进行半持续SRS资源集合或半持续SRS资源的发送，具体如步骤304a。
步骤304a，响应于终止终端设备采用目标天线切换配置，向终端设备发送与第一MAC层信令对应的携带指示信息的去激活MAC层信令。
其中，第一MAC层信令对应的去激活MAC层信令携带的指示信息，即前述的目标SRS资源配置的指示信息，该指示信息的具体形式参见其它各实施例中相关部分的描述，本实施例中对此不再赘述。
在另一些场景下，需要激活的目标SRS资源配置包括的SRS资源集合是非周期SRS资源集合，或者，SRS资源是非周期SRS资源，则执行步骤303b至步骤305b。
步骤303b，向终端设备发送第二MAC层信令，以激活终端设备的目标SRS资源配置中的至少一个非周期SRS资源集合或非周期SRS资源。
其中，第二MAC层信令，携带目标SRS资源配置的指示信息，用于激活终端设备的一个SRS资源配置，激活的SRS资源配置是目标SRS资源配置。
步骤304b，向终端设备发送DCI信令，以触发目标SRS资源配置进行非周期SRS资源集合或非周期SRS资源的发送。
其中，DCI信令，携带目标SRS资源配置的指示信息，用于触发已配置的一个SRS资源配置中属于目标SRS资源配置的非周期SRS资源集合或非周期SRS资源的发送。
DCI信令中，该指示信息处于目标指示域。
作为一种可能的实现方式，目标指示域，是扩展比特位的SRS资源域。从而可以指示更多种可能的SRS资源配置，例如，可以扩展为3bit，用于支持不同SRS资源配置的指示需求。SRS资源域中不同的数值可以指示不同的非周期性SRS资源触发(periodic SRS-Resource Trigger)。
作为另一种可能的实现方式，目标指示域，是重定义的SRS资源域，即包含的比特位与各天线切换配置对应的SRS资源集有对应关系的SRS资源域。目标指示域通过比特图，确定是否使能对应的SRS资源配置，将使能的SRS资源配置作为目标资源配置。例如：分别配置各比特位对应的天线切换配置，以基于天线切换配置和SRS资源配置之间的关系，间接确定各比特位对应的SRS资源配置。又或者例如，配置各比特位与各SRS资源配置的SRS资源(resource set)的标识(ID)之间的对应关系。目标指示域还可以通过码点，确定是否使能对应的SRS资源配置，将使能的SRS资源配置作为目标资源配置。
进一步地，在步骤304b之后，若需要终止终端设备采用目标天线切换配置，还需要指示该终端设备对对应的目标SRS资源配置去激活，具体如步骤305b。
步骤305b，响应于终止终端设备采用目标天线切换配置，向终端设备发送与第一MAC层信令对应的携带该指示信息的去激活MAC层信令。
本公开实施例的天线切换配置的切换方法，通过根据当前BWP上终端设备待切换至的目标天线切换配置，向该终端设备发送用于激活对应的目标SRS资源配置的指示信息，从而终端设备接收网络设备发送的目标SRS配置的指示信息之后，根据目标SRS配置的指示信息，在当前BWP上切换至对应的目标天线切换配置。由此，无需进行BWP切换或者RRC重配置过程，即可实现终端设备在当前BWP上的天线切换配置切换，提高了天线切换配置的切换灵活性，降低了切换的复杂度。

如图4所示，包括以下步骤：
步骤401，接收网络设备发送的目标SRS资源配置的指示信息。
在一些可能的实现方式中，用于激活目标SRS资源配置的指示信息，可以承载于控制信令中。该控制信令可以包括MAC层信令，例如MAC-CE信令；还可以是DCI信令。本实施例中，对于指示信息的具体形式不作限定。
指示信息的具体实现形式存在至少以下几种可能：

网络设备配置了该终端设备的天线切换配置与SRS资源配置之间的映射关系。
其中，作为一种可能的实现方式，网络设备对该终端设备的每个天线切换配置，配置了对应的一种SRS资源配置。
或者，作为另一种可能的实现方式，网络设备对该终端设备的至少一个天线切换配置，配置了对应的一种SRS资源配置。这里的一种SRS资源配置，包含了一个或多个SRS资源集合，其中，每个SRS资源集合中包含至少一个SRS资源。目标SRS资源配置，是所配置的至少一个天线切换配置中的一个，或者，是所配置的至少一个天线切换配置中的一个或多个SRS资源集合中的部分SRS资源集合，或者，是所配置的至少一个天线切换配置中的一个或多个SRS资源集合中的至少部分SRS资源。
由于网络设备已配置了该终端设备的天线切换配置与SRS资源配置之间的映射关系，从而在确定终端设备待切换至的目标天线切换配置之后，可以根据这种映射关系，指示终端设备对应的目标SRS资源配置，即向终端设备发送用于激活目标SRS资源配置的指示信息。从而终端设备在接收到指示信息后，根据已知的终端设备的天线切换配置与SRS资源配置之间的映射关系，确定需切换至的目标天线切换配置。

在另一些场景下，需要激活的目标SRS资源配置包括的SRS资源集合是非周期SRS资源集合，或者，SRS资源是非周期SRS资源，则执行步骤503b至步骤506b。
步骤503b，响应于网络设备发送的DCI信令，触发一个或多个SRS资源配置中的目标SRS资源配置，以及采用目标天线切换配置，对目标SRS资源配置中非周期SRS资源集合或非周期SRS资源进行发送。
其中，DCI信令，携带有目标SRS资源配置的指示信息，用于触发已配置的多个SRS资源配置中的目标SRS资源配置进行非周期SRS资源集合或非周期SRS资源的发送。
DCI信令中，该指示信息处于目标指示域。
作为一种可能的实现方式，目标指示域，是扩展比特位的SRS资源域。从而可以指示更多种可能的SRS资源配置，例如，可以扩展为3bit，用于支持不同SRS资源配置的指示需求。SRS资源域中不同的数值可以指示不同的非周期性SRS资源触发(periodic SRS-Resource Trigger)。
作为另一种可能的实现方式，目标指示域，是重定义的SRS资源域，即包含的比特位与各天线切换配置对应的SRS资源集有对应关系的SRS资源域。目标指示域通过比特图，确定是否使能对应的SRS资源配置，将使能的SRS资源配置作为目标资源配置。例如：分别配置各比特位对应的天线切换配置，以基于天线切换配置和SRS资源配置之间的关系，间接确定各比特位对应的SRS资源配置。又或者例如，配置各比特位与各SRS资源配置的SRS资源(resource set)的标识(ID)之间的对应关系。目标指示域还可以通过码点，确定是否使能对应的SRS资源配置，将使能的SRS资源配置作为目标资源配置。
本公开实施例的天线切换配置的切换方法，通过根据当前BWP上终端设备待切换至的目标天线切换配置，向该终端设备发送用于激活对应的目标SRS资源配置的指示信息，从而终端设备接收网络设备发送的目标SRS配置的指示信息之后，根据目标SRS配置的指示信息，在当前BWP上切换至对应的目标天线切换配置。由此，无需进行BWP切换或者RRC重配置过程，即可实现终端设备在当前BWP上的天线切换配置切换，提高了天线切换配置的切换灵活性，降低了切换的复杂度。
图6为本公开实施例所提供的另一种天线切换配置的切换方法的流程示意图，应用于终端设备。
如图6所示，包括以下步骤：
步骤601，接收网络设备发送的携带第二配置信息的高层信令，其中，第二配置信息，是参考天线切换配置对应的SRS资源配置，参考天线切换配置对应的SRS资源配置包括一个或多个SRS资源集合，各SRS资源集合包括至少一个SRS资源。
高层信令，例如可以是RRC信令。高层信令预先配置参考天线切换配置对应的SRS资源配置，由于配置的一个SRS资源配置中包括一个或多个SRS资源集合，且各SRS资源集合中包括至少一个SRS资源，后续便可以通过SRS资源配置中动态选择部分SRS资源集合，或者SRS资源作为目标SRS资源配置，从而可以实现对终端设备的天线切换配置的动态切换。也就是说，后续待切换至的目标天线切换配置所对应的目标SRS资源配置，是终端设备的参考天线切换配置所对应的一个或多个SRS资源集合中的至少部分SRS资源。
其中，参考天线切换配置，包括网络设备选择的一种天线切换配置，或者，终端设备支持的最高能力对应的最高天线切换配置。
作为一种可能的实现方式，网络设备选择的一种天线切换配置可以是终端设备当前采用的天线切换配置。
作为另一种可能的实现方式，网络设备选择的一种天线切换配置可以是从终端设备支持的天线切换配置中依据设定规则确定的一种天线切换配置，例如在一些场景下，网络设备可以选择终端设备支持的最高能力对应的最高天线切换配置。
基于终端设备的收发能力，根据收天线和发天线的数量，可以确定该终端设备支持的最高能力对应的最高天线切换配置。在一些实现方式中，最高天线切换配置，可以是具有最大收天线数量，或者，可以是具有最大发天线数量的天线切换配置，或者，可以是既具有最大收天线数量也具有最大发天线数量的天线切换配置。
步骤602，根据第二配置信息，确定参考天线切换配置对应SRS资源配置中的一个或多个SRS资源集合。
网络设备通过对参考天线切换配置，在当前BWP上配置对应的一个或多个SRS资源集合作为参考天线切换配置对应的一SRS资源配置，以便后续指示终端设备进行天线切换配置的切换时，在参考天线切换配置对应的SRS资源配置中的一个或多个SRS资源集合的范围内，动态指示需激活的SRS资源集合或SRS资源，从而终端设备可以根据动态指示目标SRS资源配置中的SRS资源集合或SRS资源所属的天线端口，以及已知的天线端口与天线物理通道之间的映射关系，确定待切换至的目标天线切换配置。
在一些场景下，需要激活的目标SRS资源配置包括的SRS资源集合是半持续SRS资源集合，或者，SRS资源是半持续SRS资源，则执行步骤603a至步骤606a。
步骤603a，接收网络设备根据当前部分带宽BWP上终端设备待切换至的目标天线切换配置，发送的第一MAC层信令。
本步骤中，第一MAC层信令，携带目标SRS资源配置的指示信息，用于激活已配置的一个SRS资源配置中的目标SRS资源配置，以使终端设备采用激活的目标SRS资源配置进行半持续SRS资源集合或半持续SRS资源的发送。
步骤604a，响应于第一MAC层信令，激活一个或多个SRS资源配置中的目标SRS资源配置，以及采用目标天线切换配置，对激活的目标SRS资源配置中的至少一个半持续SRS资源集合或半持续SRS资源进行发送。
进一步地，在步骤604a之后，若需要终止终端设备采用目标天线切换配置，以及停止采用该目标天线切换配置进行半持续SRS资源集合或半持续SRS资源的发送，还需要指示该终端设备对对应的目标SRS资源配置去激活，以停止进行半持续SRS资源集合或半持续SRS资源的发送，具体如步骤605a和步骤606a。
步骤605a，接收第一MAC层信令对应的携带指示信息的去激活MAC层信令。
其中，第一MAC层信令对应的去激活MAC层信令携带的指示信息，即前述的目标SRS资源配置的指示信息，该指示信息的具体形式参见其它各实施例中相关部分的描述，本实施例中对此不再赘述。
步骤606a，对目标SRS资源配置中的半持续SRS资源集合或半持续SRS资源去激活，并终止采用目标天线切换配置。
在另一些场景下，需要激活的目标SRS资源配置包括的SRS资源集合是非周期SRS 资源集合，或者，SRS资源是非周期SRS资源，则执行步骤603b至步骤606b。
步骤603b，接收网络设备发送的第二MAC层信令。
其中，第二MAC层信令，携带目标SRS资源配置的指示信息，用于激活终端设备的一个SRS资源配置，激活的SRS资源配置是目标SRS资源配置。
步骤604b，响应于第二MAC层信令，激活终端设备的目标SRS资源配置，并切换至对应的目标天线切换配置。
由于网络设备已预先配置了终端设备支持的一个参考天线切换配置所对应的SRS资源配置，从而基于第二MAC层信令中指示的目标SRS资源配置，可以从参考天线切换配置对应的SRS资源配置中，确定至少部分SRS资源集合或者SRS资源。根据SRS资源集合或SRS资源对应的天线物理通道，确定并切换至对应的目标天线切换配置。
步骤605b，响应于网络设备发送的DCI信令，触发一个或多个SRS资源配置中的目标SRS资源配置，以及采用目标天线切换配置，对目标SRS资源配置中非周期SRS资源集合或非周期SRS资源进行发送。
其中，DCI信令，携带目标SRS资源配置的指示信息，用于触发已配置的一个SRS资源配置中属于目标SRS资源配置的非周期SRS资源集合或非周期SRS资源的发送。
DCI信令中，该指示信息处于目标指示域。
作为一种可能的实现方式，目标指示域，是扩展比特位的SRS资源域。从而可以指示更多种可能的SRS资源配置，例如，可以扩展为3bit，用于支持不同SRS资源配置的指示需求。SRS资源域中不同的数值可以指示不同的非周期性SRS资源触发(periodic SRS-Resource Trigger)。
作为另一种可能的实现方式，目标指示域，是重定义的SRS资源域，即包含的比特位与各天线切换配置对应的SRS资源集有对应关系的SRS资源域。目标指示域通过比特图，确定是否使能对应的SRS资源配置，将使能的SRS资源配置作为目标资源配置。例如：分别配置各比特位对应的天线切换配置，以基于天线切换配置和SRS资源配置之间的关系，间接确定各比特位对应的SRS资源配置。又或者例如，配置各比特位与各SRS资源配置的SRS资源(resource set)的标识(ID)之间的对应关系。目标指示域还可以通过码点，确定是否使能对应的SRS资源配置，将使能的SRS资源配置作为目标资源配置。
进一步地，在步骤605b之后，若需要终止终端设备采用目标天线切换配置，还需要指示该终端设备对对应的目标SRS资源配置去激活，具体如步骤606b。
步骤606b，接收网络设备发送的第二MAC层信令对应的去激活MAC层信令，响应于第二MAC层信令对应的去激活MAC层信令，对目标SRS资源配置中的非周期SRS资源集合或非周期SRS资源去激活，并终止采用目标天线切换配置。
