在NR系统中，支持64种探测参考信号(Sounding Reference Signal，SRS)带宽配置方式，一个 SRS资源可配置的最小带宽为4个资源块(Resource Block，RB)，最大带宽是272个RB。
在一些场景中，针对不同的SRS用途，基站可以为终端配置不同的SRS资源集，并通过高层信令指示SRS资源集的用途，例如，SRS资源集可以用于天线切换(antenna switching)。
NR系统中，支持基站侧利用信道互易性通过测量SRS获取下行信道信息。受限于成本和硬件的限制，终端设备同时发送的天线数量可能少于接收天线的数量，从而导致不同的终端设备具有不同的天线收发能力。为了支持发送天线数少于接收天线数的UE也能通过信道互易性获取下行信息，采用天线切换发送的方式。
在相关技术中，终端设备的天线收发能力包括：发送天线数与接收天线数相同(即T＝R)，发送天线数为1且接收天线数为2(即1T2R)，发送天线数为1且接收天线数为4(即1T4R),发送天线数为2且接收天线数为4(即2T4R)。
因此，如何进行其他天线收发能力(例如，发送天线数为3或6等)的天线切换是一项亟需解决的问题。

在本申请实施例中，发送天线数关联SRS端口数，接收天线数关联天线端口(Antenna Port，AP)数。发送天线数是可支持的发送通道数，接收天线数为可支持的接收通道数。
在本申请实施例中，SRS资源可以理解为：用于SRS传输的资源(该资源包括时域，频域，码域资源)，或者，终端设备在该SRS资源上发送SRS。
在一些实施例中，SRS天线切换的配置信息根据频段和/或该终端设备的SRS天线切换能力确定。
换言之，SRS天线切换的配置信息与频段和/或该终端设备的SRS天线切换能力关联。
可选地，这里的频段可以指终端设备的工作频段，或者终端设备可以支持的任意频段。
即SRS天线切换的配置信息是根据终端设备的工作频段确定的，或者，SRS天线切换的配置信息是根据终端设备支持的SRS天线切换能力确定的，或者，SRS天线切换的配置信息是根据终端设备的工作频段和终端设备支持的SRS天线切换能力确定的。
例如，网络设备根据不同的频段(例如工作频段)，给终端设备配置对应的SRS天线切换的配置信息。
又例如，网络设备可以给终端设备配置多个SRS天线切换的配置信息，每个SRS天线切换的配置信息对应相应的频段，终端设备可以根据当前的工作频段使用对应的SRS天线切换的配置信息进行SRS的发送。
例如，终端设备支持的SRS天线切换能力包括第一SRS天线切换能力，则SRS天线切换的配置信息可以包括第一配置信息，该第一配置信息是根据第一SRS天线切换能力确定的。
又例如，终端设备支持的SRS天线切换能力包括第二SRS天线切换能力，则该SRS天线切换的配置信息可以包括第二配置信息，该第二配置信息是根据第二SRS天线切换能力确定的。
再例如，终端设备支持的SRS天线切换能力包括第三SRS天线切换能力，则SRS天线切换的配置信息可以包括第三配置信息，该第三配置信息是根据第三SRS天线切换能力确定的。
在一些实施例中，该终端设备支持的SRS天线切换能力与工作频段关联。例如，该终端设备在不同的工作频段对应不同的SRS天线切换能力。
作为示例，在第一频段，终端设备支持第一天线切换能力，在第二频段，终端设备支持第二天线切换能力，则在第一频段，SRS天线切换的配置信息是根据第一SRS天线切换能力确定的，在第二频段，SRS天线切换的配置信息是根据第二SRS天线切换能力确定的。
在本申请一些实施例中，该终端设备支持的SRS天线切换能力包括以下中的至少一项：
该终端设备支持的发送天线数和接收天线数的组合；
该终端设备支持的传输层数；
相邻两次SRS资源之间的保护间隔；
该终端设备支持回退的发送天线数和接收天线数的组合集，其中，该组合集包括至少两个发送天线数和接收天线数的组合。
作为示例而非限定，该终端设备支持的发送天线数和接收天线数的组合可以包括以下中的至少一个：
发送天线数为1和接收天线数为1的组合，即1T1R，或者t1r1，对应的发送通道数为1；
发送天线数为1和接收天线数为2的组合，即1T2R，或者t1r2，对应的发送通道数为1；
发送天线数为2和接收天线数为2的组合，即2T2R，或者t2r2，对应的发送通道数为2；
发送天线数为2和接收天线数为4的组合，即2T4R，或者t2r4，对应的发送通道数为2；
发送天线数为4和接收天线数为4的组合，即4T4R，或者t4r4，对应的发送通道数为4；
发送天线数为4和接收天线数为8的组合，即4T8R，或者t4r8，对应的发送通道数为4。

可选地，该终端设备支持的传输层数可以是该终端设备支持的上行MIMO层数，下行MIMO层数，上行传输支持的端口数，或下行传输支持的端口数。
可选地，该保护间隔可以小于或等于2个符号。例如，保护间隔为0个符号，或为1个符号，或为2个符号等。又例如，保护间隔为0微秒或100微秒等。终端设备进行天线端口切换需要一定的时间，UE在进行天线端口切换的过程中，不能发送任何上行信息，即需要为终端设备配置保护间隔。
在一些实施例中，该保护间隔与终端设备在工作频段上支持的SRS天线切换能力相关。
例如，对于某些SRS天线切换能力，终端设备支持的相邻两次SRS资源之间的保护间隔为1微秒。
可选地，若终端设备上报保护间隔为0符号，则表示期望接收网络设备发送特定的SRS天线切换的配置信息，例如，该特定的SRS天线切换的配置信息包括以下至少之一：SRS资源集的数量为第一数量，SRS资源的数量为第二数量，SRS端口的数量为第三数量。
在一些实施例中，终端设备向网络设备上报终端设备支持回退的发送天线数和接收天线数的组合集。
例如，终端设备支持回退的发送天线数和接收天线数的组合集可以为{6T8R，4T8R，3T8R，3T4R，2T4R，1T2R}，或者为{6T8R，2T4R，2T2R，1T2R，1T1R}，或者为{6T8R，2T4R，1T4R，2T2R，1T2R，1T1R}。
又例如，终端设备支持回退的发送天线数和接收天线数的组合集可以为{3T4R，2T4R，1T2R}，或者，{3T4R，2T4R，1T2R，1T1R}。
再例如，终端设备支持回退的发送天线数和接收天线数的组合集可以为{3T8R，3T4R，2T4R，1T2R}，或者，{3T8R，3T4R，2T4R，1T2R，1T1R}。
再例如，终端设备支持回退的发送天线数和接收天线数的组合集可以为{3T6R，3T4R，2T4R，1T2R}，或者，{3T6R，3T4R，2T4R，1T2R，1T1R}。
在一些实施例中，终端设备支持回退的发送天线数和接收天线数的组合集可以根据终端设备支持的发送天线数和接收天线数的组合确定，也就是说，在终端设备支持不同的发送天线数和接收天线数的组合时，终端设备支持回退的组合集可能不同。
例如，终端设备支持6T8R，终端设备支持回退的发送天线数和接收天线数的组合集可以为{6T8R，4T8R，3T8R，3T4R，2T4R，1T2R}，或者为{6T8R，2T4R，2T2R，1T2R，1T1R}，或者为{6T8R，2T4R，1T4R，2T2R，1T2R，1T1R}。

再例如，终端设备支持3T8R，终端设备支持回退的发送天线数和接收天线数的组合集可以为{3T8R，3T4R，2T4R，1T2R}，或者，{3T8R，3T4R，2T4R，1T2R，1T1R}。
再例如，终端设备支持3T6R，终端设备支持回退的发送天线数和接收天线数的组合集可以为{3T6R，3T4R，2T4R，1T2R}，或者，{3T6R，3T4R，2T4R，1T2R，1T1R}。
在本申请一些实施例中，该终端设备可以向网络设备上报该终端设备的SRS天线切换能力。
例如，该终端设备可以通过用户设备能力(UE capability)消息元素(information element，IE)上报该终端设备的SRS天线切换能力。
具体地，终端设备可以通过UE capability IE中的已有字段或新增字段上报该终端设备的SRS天线切换能力。
在一些实施例中，该终端设备的SRS天线切换能力包括以下中的至少一个：

在一些实施例中，终端设备通过第一状态指示第一SRS天线切换能力，和/或，通过第二状态指示第二SRS天线切换能力，和/或，通过第三状态指示第三SRS天线切换能力。
在一些实施例中，该第一状态，该第二状态和该第三状态可以是同一字段中的不同状态，例如，UE capability IE中的SRS天线切换(srs-TxSwitch)字段中的不同状态，或者，也可以是不同字段中的状态，例如通过UE capability IE中的不同字段，分别指示该第一状态，该第二状态和该第三状态。
作为一种实现方式，可以在UE capability IE中支持的SRS发送端口切换(supportedSRS-TxPortSwitch)字段添加终端设备支持的SRS天线切换能力，例如，第一SRS天线切换能力，和/或第二SRS天线切换能力，和/或第三SRS天线切换能力。
作为示例，当终端设备支持第一SRS天线切换能力(即6T8R)、第二SRS天线切换能力(即3T4R)和第三SRS天线切换能力(即3T8R)时，UE capability IE中的srs-TxSwitch字段可以表示为：
Figure PCTCN2021122199-appb-000001
作为另一种实现方式，可以在UE capability IE中新增字段，例如，supportedSRS-TxPortSwitch-v18字段，来上报终端设备支持第一SRS天线切换能力、第二SRS天线切换能力和第三SRS天线切换能力中的一种或多种。
作为示例，当终端设备支持第一SRS天线切换能力、第二SRS天线切换能力和第三SRS天线切换能力时，UE capability IE中的srs-TxSwitch字段可以表示为：
Figure PCTCN2021122199-appb-000002
在一些实施例中，终端设备可以通过UE capability IE中的已有字段(例如，上行MIMO层数(MIMO-LayersUL)字段)或，新增字段指示终端设备支持的传输层数，例如3层，和或，6层，和/或8层。
作为示例，当终端设备支持的上行传输层数包括3层，6层和8层时，UE capability IE中的MIMO-LayersUL字段可以表示为：
MIMO-LayersUL::＝ENUMERATED{oneLayer,twoLayers,fourLayers,threeLayers,sixLayers,eightLayers}。
作为示例，当终端设备支持的上行传输层数包括3层，6层和8层时，可以在UE capability IE中新增字段，例如，MIMO-LayersUL-v18字段，来上报终端设备支持的传输层数。则MIMO-LayersUL-v18 字段可以表示为：
MIMO-LayersUL-v18::＝ENUMERATED{threeLayers,sixLayers,eightLayers}。
在一些实施例中，终端设备可以通过UE capability IE中的已有字段(例如，上行发送切换周期(uplinkTxSwitchingPeriod-r18)字段)或，新增字段指示终端设备支持的相邻两次SRS资源之间的保护间隔。作为示例，uplinkTxSwitchingPeriod-r18字段可以表示为：
uplinkTxSwitchingPeriod-r18ENUMERATED{n0us,n100us,n35us,n140us,n210us}。
在一些实施例中，终端设备可以通过UE capability IE中的已有字段(例如，支持的SRS发送端口切换(supportedSRS-TxPortSwitch-v1610)字段)，或新增字段指示终端设备支持回退的发送天线数和接收天线数的组合集。
如前所述，终端设备向网络设备上报终端设备支持回退的发送天线数和接收天线数的组合集。
作为一个示例，终端设备支持回退的发送天线数和接收天线数的组合集可以为{6T8R，4T8R，3T8R，3T4R，2T4R，1T2R}，则supportedSRS-TxPortSwitch-v1610字段可以表示为：

应理解，在本申请实施例中，终端设备的天线收发能力可以为用于天线切换时的天线收发能力，或者，终端设备的天线收发能力可以为物理天线的天线收发能力。
以下，结合具体实施例，说明前述SRS天线切换能力对应的SRS天线切换的配置信息的具体实现。
实施例1：
在该实施例1中，该终端设备支持第一SRS天线切换能力，即终端设备支持的发送天线数为6，接收天线数为8。
在一些实施例中，SRS天线切换的配置信息包括M 1个SRS资源集，每个SRS资源集包括N 1个SRS资源，该N 1个SRS资源所占用的时域位置不同，该M 1为正整数，该N 1为正整数。
即每个SRS资源集包括的SRS资源数可以相同。
在另一些实施例中，若M 1大于1，M 1个SRS资源集中的每个SRS资源集包括的SRS资源数也可以不同，或者，M 1个SRS资源集中存在至少两个SRS资源集包括的SRS资源数不同。
例如，M 1个SRS资源集包括第一SRS资源集和第二SRS资源集，第一SRS资源集包括的SRS 资源数和第二SRS集包括的SRS资源数不同。可选地，M 1个SRS资源集还可以包括第三SRS资源集，第三SRS资源集包括的SRS资源集与第一SRS资源集包括的SRS资源集可以相同，或者也可以不同。
以下以每个SRS资源集包括相同数量的SRS资源为例进行说明，但本申请并不限于此。在一些实施例中，当M 1大于1时，每个SRS资源集的类型各不相同，或者，该M 1个SRS资源集的类型都是“非周期”。
例如，M 1＝3，该3个SRS资源集的类型分别为“周期”，“半静态(也可以理解为半持续(semi-persistent))”，“非周期”，即，第一个SRS资源集中的资源为周期配置的，第二个SRS资源集中的资源为半静态配置的，第三个SRS资源集中的资源为非周期调度的。
再例如，M 1＝3，该3个SRS资源集的类型都为“非周期”，即，第一个SRS资源集中的资源，第二个SRS资源集中的资源，第三个SRS资源集中的资源都是非周期调度的。
在一些实施例中，该N 1个SRS资源所占用的时域位置不同可以理解为：该N 1个SRS资源占用不同的正交频分复用(Orthogonal frequency-division multiplexing，OFDM)符号，或者，该N 1个SRS资源占用不同时隙的OFDM符号。
在实施例1中，M 1个SRS资源集共包括K1个SRS资源，该K1个SRS资源中的每个SRS资源包括至少一个SRS端口，该至少一个SRS端口中的每个SRS端口关联一个天线端口。将该K1个SRS资源包括的SRS端口数之和记为P1，则K1个SRS资源共包括P1个SRS端口，该P1个SRS端口关联的天线端口的数量之和大于或等于8。
在实施例1中，M 1个SRS资源集共包括K1个SRS资源，K1个SRS资源共包括P1个SRS端口，该P1个SRS端口关联P1个天线端口，其中，该P1个天线端口包括所有的天线端口。即基于该K1个SRS资源进行天线切换有利于遍历所有的天线端口，获取全面的下行信道信息。
因此，在实施例1，网络设备通过配置至少一个SRS资源集，每个SRS资源集包括N 1个SRS资源，N 1个SRS资源中的每个SRS资源包括至少一个SRS端口，至少一个SRS端口中的每个SRS端口关联到一个天线端口，N 1个SRS资源包括的所有的SRS端口关联不同的天线端口，并且所有的SRS资源包括的SRS端口可以关联所有的天线端口，例如，3个SRS资源包括的所有SRS端口关联8个天线端口，或者说，每个天线端口都可以关联到至少一个SRS资源，这样，终端设备根据该配置信息发送SRS，可遍历所有的天线端口，从而可以获得完整的下行信道信息。
在该实施例1中，M 1个SRS资源集中的任意两个SRS资源包括的SRS端口关联的天线端口不同。
以M 1个SRS资源集中的第一SRS资源和第二SRS资源为例说明，第一SRS资源和第二SRS资源属于相同的SRS资源集或不同的SRS资源集。第一SRS资源包括的SRS端口关联第一天线端口，第二SRS资源包括的SRS端口关联第二天线端口，则第一SRS资源包括的SRS端口关联的天线端口和第二SRS资源包括的SRS端口关联的天线端口不同，可以理解为，第一天线端口与第二天线端口至少部分天线端口不同，或者，至少部分天线端口不重叠。
例如，该第一SRS资源包括X个SRS端口，该X个SRS端口关联X个天线端口，该第二SRS资源包括Y个SRS端口，该Y个SRS端口关联Y个天线端口，X个天线端口和Y个天线端口不同可以包括：X个天线端口与Y个天线端口的端口索引完全不同，或者，X个天线端口与Y个天线端口的至少一个端口索引不同，或者，X个天线端口包括与该Y个天线端口不同的至少一个天线端口，或者，该Y个天线端口包括与X个天线端口不同的至少一个天线端口，其中，X，Y为正整数。
示例一：X大于Y，X个天线端口包括Y个天线端口以及其他天线端口，即Y个天线端口为X个天线端口的子集。也可以理解为，Y个天线端口的端口索引是X个天线端口的端口索引的子集。
示例二：X小于Y，Y个天线端口包括X个天线端口以及其他天线端口，即X个天线端口为Y个天线端口的子集。也可以理解为，X个天线端口的端口索引是Y个天线端口的端口索引的子集。
示例三：该X个天线端口包括Z个天线端口和P个天线端口，Y个天线端口包括Z个天线端口和Q个天线端口，其中，该P个天线端口和Q个天线端口完全不同。即X个天线端口和Y个天线端口部分重叠，其中，Z，P，Q为正整数。也可以理解为，X个天线端口的端口索引与Y个天线端口的端口索引有部分端口索引相同。
示例四：该X个天线端口和该Y个天线端口完全不同。即X个天线端口和Y个天线端口完全不重叠。也可以理解为，X个天线端口和Y个天线端口的端口索引完全不同。
需要说明的是，在本申请实施例中，索引为0的SRS资源集可以指第一个SRS资源集，记为SRS资源集0，索引为1的SRS资源可以指第二个SRS资源集，记为SRS资源集1，索引为2的SRS资源集可以指第三个SRS资源集，记为SRS资源2，依次类推；类似地，索引为0的SRS资源可以指SRS资源集中的第一个SRS资源，记为SRS资源0，索引为1的SRS资源可以指SRS资源集中的第 二个SRS资源，记为SRS资源1，索引为2的SRS资源可以指SRS资源集中的第三个SRS资源，记为SRS资源2，依次类推。
可选地，在该实施例1中，M 1个SRS资源集包括的SRS资源的总个数不超过第一阈值，可选地，第一阈值可以为4。
以下，结合实施例1-1至实施例1-3，说明SRS天线切换的配置信息的典型实现，但本申请并不限于此。
实施例1-1：M 1为1或2，N 1为2或1。
在一些实施例中，M 1个SRS资源集中的每个SRS资源集包括的SRS资源数可以相同。例如，M 1＝1，N 1＝2，或者M 1＝2，N 1＝2等。
以N 1＝2为例，该N 1个SRS资源中的索引为0的SRS资源包括S 1个SRS端口，该N 1个SRS资源中的索引为1的SRS资源包括S 2个SRS端口，其中，该S 1个SRS端口关联S 1个天线端口，该S2个SRS端口关联S2个天线端口，该S 1个天线端口与该S 2个天线端口不同，且S 1+S 2＝8。
即，可以配置1个或2个SRS资源集，每个SRS资源集包括2个SRS资源，每个SRS资源包括的SRS端口关联不同的天线端口，并且这两个SRS资源包括的SRS端口可以关联到所有的天线端口，即8个天线端口，或者，每个天线端口都可以关联到至少一个SRS资源，这样，通过发送两次SRS，即可遍历所有的天线端口，从而可以获得所有下行信道的质量信息，同时减少SRS资源与其他上行传输发生冲突的概率。
应理解，在该实施例1中，该S 1个天线端口与该S 2个天线端口不同的含义可以参考前文X个天线端口和Y个天线端口不同的相关说明，为了简洁，这里不再赘述。
在一些实施例中，例如，M 1为2，N 1为1，该M 1个SRS资源集中的索引为0的SRS资源包括S 1个SRS端口，该M 1个SRS资源集中的索引为1的SRS资源包括S 2个SRS端口，该S 1个SRS端口关联S 1个天线端口，该S 2个SRS端口关联S 2个天线端口，该S 1个天线端口与该S 2个天线端口不同，且S 1+S 2＝8。
以下，结合配置1～配置3，说明实施例1-1的具体实现方式。
其中，在图3-图8的示例中，发送通道对应的端口号从左向右依次为0,1,2,3,4,5，即TX0～TX5，接收通道对应的端口号从左向右为0,1,2,3,4,5,6,7，即AP0～AP7。
配置1：M 1＝1，N 1＝2，S 1＝6，S 2＝2。
即，SRS资源集中的第一个SRS资源包括6个SRS端口，第二个SRS资源包括2个SRS端口。
图3是基于配置1的发送通道、接收通道和SRS资源的对应关系示意图。
如图3所示，SRS资源集中的SRS资源0包括的SRS端口数为6，SRS资源1包括的SRS端口数为2。发送通道端口、接收通道端口和SRS资源的对应关系如表1所示。
表1
端口\资源 SRS资源0 SRS资源1
TX0 AP0  
TX1 AP1  
TX2 AP2  
TX3 AP3  
TX4 AP4 AP6
TX5 AP5 AP7
即SRS资源0包括的SRS端口关联天线端口0～天线端口5，SRS资源1包括的SRS端口关联天线端口6和天线端口7，即这两个SRS资源包括SRS端口可以关联所有的天线端口，这样，发送两次SRS即可获取完整的下行信道信息。
应理解，表1中的发送通道端口、接收通道端口和SRS资源的对应关系仅为示例，发送通道端口、接收通道端口和SRS资源也可以有其他的对应关系，只要保证每个SRS资源包括的SRS端口关联不同的接收通道端口，并且所有SRS资源包括的SRS端口可以关联所有的天线端口即可，或者说，每个天线端口至少关联一个SRS资源即可。
例如，SRS资源集0中的SRS资源1包括的SRS端口可以是发送通道端口TX0和TX1，或是发送通道端口TX2和TX3，该SRS端口关联天线端口6和天线端口7。
进一步地，由于发送通道4和发送通道5需要在两个SRS资源之间进行功率调整，则SRS资源0和SRS资源1需要间隔至少一个OFDM符号。
配置2：M 1＝1，N 1＝2，S 1＝4，S 2＝4。
即，SRS资源集0中的第一个SRS资源包括4个SRS端口，第二个SRS资源包括4个SRS端口。
图4是基于配置2的发送通道、接收通道和SRS资源的对应关系示意图。
如图4所示，SRS资源集索引为0，其中，SRS资源0包括的SRS端口数为4，SRS资源1包括的SRS端口数为4。发送通道端口、接收通道端口和SRS资源的对应关系如表2所示。
表2
端口\资源 SRS资源0 SRS资源1
TX0 AP0  
TX1 AP1  
TX2 AP2 AP4
TX3 AP3 AP5
TX4   AP6
TX5   AP7
即SRS资源0包括的SRS端口关联天线端口0～天线端口3，SRS资源1包括的SRS端口关联天线端口4～天线端口7，即这两个SRS资源包括SRS端口可以关联所有的天线端口，这样，发送两次SRS即可获取完整的下行信道信息。
配置3：M 1＝2，N 1＝1，S 1＝4，S 2＝4。
即，SRS资源集中的第一个SRS资源包括4个SRS端口，第二个SRS资源包括4个SRS端口。
图5是基于配置3的发送通道、接收通道和SRS资源的对应关系示意图。
如图5所示，SRS资源集0中的SRS资源0包括的SRS端口数为4，SRS资源集1中的SRS资源0包括的SRS端口数为4。发送通道端口、接收通道端口和SRS资源的对应关系如表3所示。
表3
端口\资源 SRS资源集0SRS资源0 SRS资源集1SRS资源0
TX0 AP0  
TX1 AP1  
TX2 AP2 AP4
TX3 AP3 AP5
TX4   AP6
TX5   AP7
由上述配置1～配置3可知，终端设备只需要发送两次SRS，即可实现天线切换，或者说，遍历所有的天线端口，有利于获取完整的下行信道信息，同时还可以减少SRS资源与其他上行传输发生冲突的概率。
实施例1-2：M 1为1或2或3，N 1为3或2或1。
在一些实施例中，M 1个SRS资源集中的每个SRS资源集包括的SRS资源数可以相同。例如，M 1＝1，N 1＝3，或者M 1＝3，N 1＝1。
以N 1＝3为例，N 1个SRS资源中的索引为0的SRS资源包括S 3个SRS端口，该N 1个SRS资源中的索引为1的SRS资源包括S 4个SRS端口，该N 1个SRS资源中的索引为2的SRS资源包括S 5个SRS端口，其中，该S 3个SRS端口关联S 3个天线端口，该S 4个SRS端口关联S 4个天线端口，该S 5个SRS端口关联S 5个天线端口，该S 3个天线端口，该S 4个天线端口和该S 5个天线端口不同，且S 3+S 4+S 5＝8。
即，可以配置1个，2个或3个SRS资源集，每个SRS资源集包括3个SRS资源，每个SRS资源包括的SRS端口关联不同的天线端口，并且这三个SRS资源包括的SRS端口可以关联到所有的天线端口，即8个天线端口，或者，每个天线端口都可以关联到至少一个SRS资源，这样，通过发送三次SRS，可遍历所有的天线端口，从而可以获得所有下行信道的质量信息。
应理解，该S 3个天线端口，该S 4个天线端口和该S 5个天线端口不同可以包括：该S 3个天线端口和该S 4个天线端口不同，该S 4个天线端口和该S 5个天线端口不同，以及该S 3个天线端口和该S 5个天线端口不同，其中，S 3个天线端口和该S 4个天线端口不同，该S 4个天线端口和该S 5个天线端口不同，以及该S 3个天线端口和该S 5个天线端口不同的说明参考前述实施例中X个天线端口与该Y个天线端口不同的说明，为了简洁，这里不再赘述。
在一些实施例中，M 1个SRS资源集中的每个SRS资源集包括的SRS资源数也可以不同，例如，M 1＝2，索引为0的SRS资源集包括A1个SRS资源，索引为1的SRS资源集包括A2个SRS资源，A1+A2＝3，例如，A1＝2，A2＝1，或A1＝1，A2＝2。也可以理解为，M 1个SRS资源集中共包括3个SRS资源。以A1＝2，A2＝1为例，索引为0的SRS资源集中的索引为0的SRS资源包括S 3个SRS端口，索引为0的SRS资源集中的索引为1的SRS资源包括S 4个SRS端口，索引为1的SRS资源集中的索引为0的SRS资源包括S 5个SRS端口，其中，该S 3个SRS端口关联S 3个天线端口，该S 4个SRS端口关联S 4个天线端口，该S 5个SRS端口关联S 5个天线端口，该S 3个天线端口，该S 4个天 线端口和该S 5个天线端口不同，且S 3+S 4+S 5＝8。
以下，结合配置4～配置5，说明实施例1-2的具体实现方式。
配置4：M 1＝1，N 1＝3，S 3＝4，S 4＝2，S 5＝2。
即，SRS资源集0中的第一个SRS资源包括4个SRS端口，第二个SRS资源包括2个SRS端口，第三个SRS资源包括2个SRS端口。
图6是基于配置4的发送通道、接收通道和SRS资源的对应关系示意图。
如图6所示，SRS资源集0中的SRS资源0包括的SRS端口数为4，SRS资源1包括的SRS端口数为2，SRS资源2包括的SRS端口数为2。图6中的发送通道端口、接收通道端口和SRS资源的对应关系如表4所示。

端口\资源 SRS资源0 SRS资源1 SRS资源2
TX0 AP0    
TX1 AP1    
TX2 AP2   AP6
TX3 AP3   AP7
TX4   AP4  
TX5   AP5  
即SRS资源0包括的SRS端口关联天线端口0～天线端口3，SRS资源1包括的SRS端口关联天线端口4～天线端口5，SRS资源2包括的SRS端口关联天线端口6～天线端口7，即这三个SRS资源包括SRS端口可以关联所有的天线端口，这样，发送三次SRS即可获取完整的下行信道信息。
在该配置4中，终端设备要通过SRS资源2发送SRS之前，需要将天线端口2和天线端口3切换为天线端口4和天线端口5，该切换过程可以与终端设备通过SRS资源1发送SRS同时进行，因此不需要保护间隔。
配置5：M 1＝2，N 1＝2或N 1＝1，S 3＝4，S 4＝2，S 5＝2。
即，SRS资源集中的第一个SRS资源包括4个SRS端口，第二个SRS资源包括2个SRS端口，第三个SRS资源包括2个SRS端口。
图7是基于配置5的发送通道、接收通道和SRS资源的对应关系示意图。
如图7所示，SRS资源集0中的SRS资源0包括的SRS端口数为4，SRS资源1包括的SRS端口数为2，SRS资源集1中的SRS资源0包括的SRS端口数为2。
即SRS资源集0中的SRS资源0包括的SRS端口关联天线端口0～天线端口3，SRS资源1包括的SRS端口关联天线端口4～天线端口5，SRS资源集1中的SRS资源0包括的SRS端口关联天线端口6～天线端口7，即这三个SRS资源包括SRS端口可以关联所有的天线端口，这样，发送三次SRS即可获取完整的下行信道信息。
并且，终端设备要通过SRS资源2发送SRS之前，需要将天线端口2和天线端口3切换为天线端口4和天线端口5，该切换过程可以与终端设备通过SRS资源1发送SRS同时进行，因此不需要保护间隔；并且，SRS资源属于两个SRS资源集，端口2和端口3在发送SRS资源的时候，不会出现端口的功率不一致的问题。
实施例1-3：M 1为1或2或3或4，N 1为4或3或2，或1。
在一些实施例中，M 1个SRS资源集中的每个SRS资源集包括的SRS资源数可以相同。例如，M 1＝1，N 1＝4，或者M 1＝4，N 1＝1。N 1个SRS资源中的索引为0的SRS资源包括S 6个SRS端口，该N 1个SRS资源中的索引为1的SRS资源包括S 7个SRS端口，该N 1个SRS资源中的索引为2的SRS资源包括S 8个SRS端口，该N 1个SRS资源中的索引为3的SRS资源包括S 9个SRS端口，其中，该S 6个SRS端口关联S 6个天线端口，该S 7个SRS端口关联S 7个天线端口，该S 8个SRS端口关联S 8个天线端口，该S 9个SRS端口关联S 9个天线端口，该S 6个天线端口，该S 7个天线端口，该S 8个天线端口和该S 9个天线端口不同，且S 6＝S 7＝S 8＝S 9。
即，可以配置1个，2个，3个或4个SRS资源集，每个SRS资源集包括4个SRS资源，每个SRS资源包括的SRS端口关联不同的天线端口，并且这四个SRS资源包括的SRS端口可以关联到所有的天线端口，即8个天线端口，或者，每个天线端口都可以关联到至少一个SRS资源，这样，通过发送四次SRS，可遍历所有的天线端口，从而可以获得所有下行信道的质量信息。
应理解，在该实施例1中，该该S 6个天线端口，该S 7个天线端口，该S 8个天线端口和该S 9个天线端口不同可以包括：该S 6个天线端口，该S 7个天线端口，该S 8个天线端口和该S 9个天线端口中的任意两组天线端口至少部分不同，或者，任意两组天线端口至少部分不重叠，具体含义参考前述实施例中的相关说明，为了简洁，这里不再赘述。
在一些实施例中，M 1个SRS资源集中的每个SRS资源集包括的SRS资源数也可以不同，例如，M 1＝2，索引为0的SRS资源集包括A3个SRS资源，索引为1的SRS资源集包括A4个SRS资源，A3+A4＝4，即A3＝2，A4＝2，或A3＝1，A4＝3，或A3＝3，A4＝1。也可以理解为，M 1个SRS资源集中共包括4个SRS资源。以A3＝2，A4＝2为例，索引为0的SRS资源集中的索引为0的SRS资源包括S 6个SRS端口，索引为0的SRS资源集中的索引为1的SRS资源包括S 7个SRS端口，索引为1的SRS资源集中的索引为0的SRS资源包括S 8个SRS端口，索引为1的SRS资源集中的索引为1的SRS资源包括S 9个SRS端口，其中，该S 6个SRS端口关联S 6个天线端口，该S 7个SRS端口关联S 7个天线端口，该S 8个SRS端口关联S 8个天线端口，该S 9个SRS端口关联S 9个天线端口，该S 6个天线端口，该S 7个天线端口，该S 8个天线端口和该S 9个天线端口不同，且S 6＝S 7＝S 8＝S 9。
以下，结合配置6，说明实施例1-3的具体实现方式。
配置6：M 1＝1，N 1＝4；S 6＝S 7＝S 8＝S 9＝6。
即，SRS资源集0中的第一个SRS资源包括6个SRS端口，第二个SRS资源包括6个SRS端口，第三个SRS资源包括6个SRS端口，第四个SRS资源包括6个SRS端口。
基于该配置6，各个发送通道端口的功率相同，不会存在端口的功率不一致问题。
图8是基于配置6的发送通道、接收通道和SRS资源的对应关系示意图。
如图8所示，SRS资源集0中的SRS资源0包括的SRS端口数为6，SRS资源1包括的SRS端口数为6，SRS资源2包括的SRS端口数为6，SRS资源3包括的SRS端口数为6。发送通道端口、接收通道端口和SRS资源的对应关系如表5所示。
表5
端口\资源 SRS资源0 SRS资源1 SRS资源2 SRS资源3
TX0 AP0 AP2 AP0 AP0
TX1 AP1 AP3 AP1 AP1
TX2 AP2 AP4 AP2 AP4
TX3 AP3 AP5 AP3 AP5
TX4 AP4 AP6 AP6 AP6
TX5 AP5 AP7 AP7 AP7
即SRS资源集0中的每个SRS资源包括的SRS端口可以关联6个天线端口，并且每个SRS资源包括的SRS端口所关联的天线端口至少部分不同，并且这四个SRS资源包括SRS端口可以关联所有的天线端口，这样，发送四次SRS可获取完整的下行信道信息。
应理解，图8和表5中的发送通道端口、接收通道端口和SRS资源的关联关系仅为示例，发送通道端口、接收通道端口和SRS资源也可以有其他的对应关系，只要保证每个SRS资源包括的SRS端口关联到不同的接收通道端口，并且所有SRS资源可以关联到所有的天线端口即可，或者说，每个天线端口至少关联一个SRS资源即可。
可替换地，发送通道端口、接收通道端口和SRS资源的关联关系也可以如表6所示，但本申请并不限于此。采用表6中的关联关系可以减少两次SRS资源之间从SRS端口到天线端口的变化，降低终端设备实现的复杂度，有利于终端设备内部器件的部署。
表6
端口\资源 SRS资源0 SRS资源1 SRS资源2 SRS资源3
TX0 AP0 AP0 AP0 AP2

TX5 AP5 AP7 AP7 AP7
实施例2：
在该实施例2中，终端设备支持第二SRS天线切换能力，即终端设备支持的发送天线数为3，接收天线数为4。
此情况下，该SRS天线切换的配置信息包括M 2个SRS资源集，每个SRS资源集包括N 2个SRS资源，该N 2个SRS资源所占用的时域位置不同，该M 2为正整数，该N 2为正整数。
即每个SRS资源集包括的SRS资源数可以相同。
在另一些实施例中，M 2大于1，M 2个SRS资源集中的每个SRS资源集包括的SRS资源数也 可以不同，或者，M 2个SRS资源集中存在至少两个SRS资源集包括的SRS资源数不同。
例如，M 2个SRS资源集包括第一SRS资源集和第二SRS资源集，第一SRS资源集包括的SRS资源数和第二SRS集包括的SRS资源数不同，可选地，M 2个SRS资源集还可以包括第三SRS资源集，第三SRS资源集包括的SRS资源集与第一SRS资源集包括的SRS资源集可以相同，或者也可以不同。以下以每个SRS资源集包括相同数量的SRS资源为例进行说明，但本申请并不限于此。
在一些实施例中，该N 2个SRS资源所占用的时域位置不同可以包括该N 2个SRS资源占用不同的OFDM符号。
在一些实施例中，当M 2大于1时，每个SRS资源集的类型各不相同，或者，M 2个SRS资源集的类型都是“非周期”。
例如，M 2＝3，3个SRS资源集的类型分别为“周期”，“semi-persistent”，“非周期”，即，第一个SRS资源集中的资源为周期配置的，第二个SRS资源集中的资源为半静态配置的，第三个SRS资源集中的资源为非周期调度的。
再例如，M 2＝3，3个SRS资源集的类型都为“非周期”。即，第一个SRS资源集中的资源，第二个SRS资源集中的资源，第三个SRS资源集中的资源都是非周期调度的。
在实施例2中，M 2个SRS资源集共包括K2个SRS资源，该K2个SRS资源中的每个SRS资源包括至少一个SRS端口，该至少一个SRS端口中的每个SRS端口关联一个天线端口。将该K2个SRS资源包括的SRS端口数之和记为P2，即K2个SRS资源共包括P2个SRS端口，该P2个SRS端口关联的天线端口的数量之和大于或等于4。
应理解，在该实施例2中，该K2个SRS资源中的任意两个SRS资源包括的SRS端口关联的天线端口不同，具体说明参考实施例1中的相关说明，为了简洁，这里不再赘述。
在一些实施例中，M 2个SRS资源集共包括K2个SRS资源，K2个SRS资源共包括P2个SRS端口，该P2个SRS端口关联P2个天线端口，其中，该P2个天线端口包括所有的天线端口。即基于该P2个SRS资源进行天线切换有利于遍历所有的天线端口，获取全面的下行信道信息。
在实施例2，网络设备通过配置至少一个SRS资源集，每个SRS资源集包括N 2个SRS资源，N 2个SRS资源中的每个SRS资源包括至少一个SRS端口，至少一个SRS端口中的每个SRS端口关联到一个天线端口，N 2个SRS资源包括的所有的SRS端口关联不同的天线端口，并且所有的SRS资源包括的SRS端口可以关联所有的天线端口，例如，3个SRS资源包括的所有SRS端口关联4个天线端口，或者说，每个天线端口都可以关联到至少一个SRS资源，这样，终端设备根据该配置信息发送SRS，可遍历所有的天线端口，从而可以获得完整的下行信道信息。
在该实施例2中，M 2个SRS资源集中的任意两个SRS资源包括的SRS端口关联的天线端口不同，具体实现参考实施例1中的相关说明，为了简洁，这里不再赘述。
可选地，在该实施例2中，M 2个SRS资源集包括的SRS资源的总个数不超过第二阈值，可选地，第二阈值可以为4。
以下，结合实施例2-1至实施例2-3，说明SRS天线切换的配置信息的典型实现，但本申请并不限于此。
实施例2-1：M 2为1或2，N 2为2或1。
在一些实施例中，M 2个SRS资源集中的每个SRS资源集包括的SRS资源数相同，例如，M 2＝2，N 2＝1或2，或M 2＝1，N 2＝2。
以N 2＝2为例，该N 2个SRS资源中的索引为0的SRS资源包括S 10个SRS端口，该N 2个SRS资源中的索引为1的SRS资源包括S 11个SRS端口，其中，该S 10个SRS端口关联S 10个天线端口，该S 11个SRS端口关联S 11个天线端口，该S 10个天线端口与该S 11个天线端口不同，且S 10+S 11＝4。
即，可以配置1个或2个SRS资源集，每个SRS资源集包括2个SRS资源，每个SRS资源包括的SRS端口关联不同的天线端口，并且这两个SRS资源包括的SRS端口可以关联到所有的天线端口，即4个天线端口，或者，每个天线端口都可以关联到至少一个SRS资源，这样，通过发送两次SRS，即可遍历所有的天线端口，从而可以获得所有下行信道的质量信息，同时减少SRS资源与其他上行传输发生冲突的概率。
应理解，在该实施例2中，该S 10个天线端口与该S 11个天线端口不同的含义可以参考实施例中的相关说明，为了简洁，这里不再赘述。
在一些实施例中，例如，M 2为2，N 1为1，该M 2个SRS资源集中的索引为0的SRS资源集中的SRS资源包括S 10个SRS端口，该M 2个SRS资源集中的索引为1的SRS资源集中的SRS资源包括S 11个SRS端口，该S 10个SRS端口关联S 10个天线端口，该S 11个SRS端口关联S 11个天线端口，该S 10个天线端口与该S 11个天线端口不同，且S 10+S 11＝4。

配置7：M 2＝1，N 2＝2，S 10＝3，S 11＝1。
即，SRS资源集0中的第一个SRS资源包括3个SRS端口，第二个SRS资源包括1个SRS端口。
图9是基于配置7的发送通道、接收通道和SRS资源的对应关系示意图。
如图9所示，SRS资源集0中的SRS资源0包括的SRS端口数为3，SRS资源1包括的SRS端口数为1。发送通道端口、接收通道端口和SRS资源的对应关系如表7所示。
表7
端口\资源 SRS资源0 SRS资源1
TX0 AP0  
TX1 AP1  
TX2 AP2 AP3
即SRS资源集0中的SRS资源0包括的SRS端口关联天线端口0～天线端口2，SRS资源1包括的SRS端口关联天线端口3，即这两个SRS资源包括SRS端口可以关联所有的天线端口，这样，发送两次SRS即可获取完整的下行信道信息，具体地，可以在一个时隙内完成天线切换。
应理解，表7中的发送通道端口、接收通道端口和SRS资源的对应关系仅为示例，发送通道端口、接收通道端口和SRS资源也可以有其他的对应关系，只要保证每个SRS资源包括的SRS端口关联不同的接收通道端口，并且所有SRS资源包括的SRS端口可以关联所有的天线端口即可，或者说，每个天线端口至少关联一个SRS资源即可。例如，SRS资源集0中的SRS资源1包括的SRS端口可以是发送通道端口TX0或发送通道端口TX1，该SRS端口关联天线端口3。
在该配置7中，SRS资源之间需要预留至少一个符号的保护间隔。配置8：M 2＝1，N 2＝2，S 10＝2，S 11＝2。

即SRS资源集0中的SRS资源0包括的SRS端口关联天线端口0～天线端口1，SRS资源1包括的SRS端口关联天线端口2～天线端口3，即这两个SRS资源包括SRS端口可以关联所有的天线端口，这样，发送两次SRS即可获取完整的下行信道信息，具体地，可以在一个时隙内完成天线切换。
在该配置8中，SRS资源之间需要预留至少一个符号的保护间隔。
实施例2-2：M 2为1或2或3，N 2为3或2或1。
在一些实施例中，M 2个SRS资源集中的每个SRS资源集包括的SRS资源数可以相同。例如，M 2＝1，N 2＝3，或者M 2＝3，N 2＝1等。
以M 2＝1，N 2＝3为例，该N 2个SRS资源中的索引为0的SRS资源包括S 12个SRS端口，该N 2个SRS资源中的索引为1的SRS资源包括S 13个SRS端口，该N 2个SRS资源中的索引为2的SRS资源包括S 14个SRS端口，其中，该S 12个SRS端口关联S 12个天线端口，该S 13个SRS端口关联S 13个天线端口，该S 14个SRS端口关联S 14个天线端口，该S 12个天线端口，该S 13个天线端口和该S 14个天线端口不同，且S 12+S 13+S 14＝4。
即，可以配置1个，2个或3个SRS资源集，每个SRS资源集包括3个SRS资源，每个SRS资源包括的SRS端口关联不同的天线端口，并且这三个SRS资源包括的SRS端口可以关联到所有的天线端口，即4个天线端口，或者，每个天线端口都可以关联到至少一个SRS资源，这样，通过发送三次SRS，即可遍历所有的天线端口，从而可以获得所有下行信道的质量信息。
应理解，该S 12个天线端口，该S 13个天线端口和该S 14个天线端口不同，包括：该S 12个天线端口，该S 13个天线端口和该S 14个天线端口中的任意两组天线端口至少部分不同，或者，任意两组天线端口至少部分不重叠，具体含义参考前述实施例中的相关说明，为了简洁，这里不再赘述。
在一些实施例中，M 2个SRS资源集中的每个SRS资源集包括的SRS资源数也可以不同，例如， M 2＝2，索引为0的SRS资源集包括A5个SRS资源，索引为1的SRS资源集包括A6个SRS资源，A5+A6＝3，例如，A5＝2，A6＝1，或A5＝1，A6＝2。也可以理解为，M 2个SRS资源集中共包括3个SRS资源。以A5＝2，A6＝1为例，索引为0的SRS资源集中的索引为0的SRS资源包括S 12个SRS端口，索引为0的SRS资源集中的索引为1的SRS资源包括S 13个SRS端口，索引为1的SRS资源集中的索引为0的SRS资源包括S 14个SRS端口，其中，该S 12个SRS端口关联S 12个天线端口，该S 13个SRS端口关联S 13个天线端口，该S 14个SRS端口关联S 14个天线端口，该S 12个天线端口，该S 13个天线端口和该S 14个天线端口不同，且S 12+S 13+S 14＝4。
以下，结合配置9，说明实施例2-2的具体实现方式。

即，SRS资源集0中的第一个SRS资源包括2个SRS端口，第二个SRS资源包括1个SRS端口，第三个SRS资源包括1个SRS端口。
图11是基于配置9的发送通道、接收通道和SRS资源的对应关系示意图。
如图11所示，SRS资源集0中的SRS资源0包括的SRS端口数为2，SRS资源1包括的SRS端口数为1，SRS资源2包括的SRS端口数为1。
作为一种实现方式，发送通道端口、接收通道端口和SRS资源的对应关系如表9所示。
表9
端口\资源 SRS资源0 SRS资源1 SRS资源2
TX0 AP0    
TX1 AP1   AP3
TX2   AP2  
即SRS资源集0中的SRS资源0包括的SRS端口关联天线端口0～天线端口1，SRS资源1包括的SRS端口关联天线端口2，SRS资源2包括的SRS端口关联天线端口3，即这三个SRS资源包括SRS端口可以关联所有的天线端口，这样，发送三次SRS即可获取完整的下行信道信息，具体地，可以在一个时隙内完成天线切换。
在该配置9中，SRS资源之间需要预留至少一个符号的保护间隔。
实施例2-3：该M 2为1或2或3或4，该N 2为4或3或2或1。
在一些实施例中，M 2个SRS资源集中的每个SRS资源集包括的SRS资源数可以相同。例如，M 2＝2，N 2＝2，或者M 2＝3，N 2＝1，或者M 2＝4，N 2＝1，或者M 2＝1，N 2＝4等。
以M 2＝1，N 2＝4为例该N 2个SRS资源中的索引为0的SRS资源包括S 15个SRS端口，该N 2个SRS资源中的索引为1的SRS资源包括S 16个SRS端口，该N 2个SRS资源中的索引为2的SRS资源包括S 17个SRS端口，该N 2个SRS资源中的索引为3的SRS资源包括S 18个SRS端口，其中，该S 15个SRS端口关联S 15个天线端口，该S 16个SRS端口关联S 16个天线端口，该S 17个SRS端口关联S 17个天线端口，该S 18个SRS端口关联S 18个天线端口，该S 15个天线端口，该S 16个天线端口，该S 17个天线端口和该S 18个天线端口不同，且S 15＝S 16＝S 17＝S 18。
即，可以配置1个，2个，3个或4个SRS资源集，每个SRS资源集包括4个SRS资源，每个SRS资源包括的SRS端口关联不同的天线端口，并且这四个SRS资源包括的SRS端口可以关联到所有的天线端口，即4个天线端口，或者，每个天线端口都可以关联到至少一个SRS资源，这样，通过发送四次SRS，即可遍历所有的天线端口，从而可以获得完整的下行信道的质量信息。
在一些实施例中，M 2个SRS资源集中的每个SRS资源集包括的SRS资源数也可以不同，例如，M 2＝2，索引为0的SRS资源集包括A7个SRS资源，索引为1的SRS资源集包括A8个SRS资源，A7+A8＝4，例如，A7＝2，A8＝2，或A7＝1，A8＝3，或A7＝3，A8＝1。也可以理解为，M 2个SRS资源集中共包括4个SRS资源。以A7＝3，A8＝1为例，索引为0的SRS资源集中的索引为0的SRS资源包括S 15个SRS端口，索引为0的SRS资源集中的索引为1的SRS资源包括S 16个SRS端口，索引为0的SRS资源集中的索引为2的SRS资源包括S 17个SRS端口，索引为1的SRS资源集中的索引为0的SRS资源包括S 18个SRS端口，其中，该S 15个SRS端口关联S 15个天线端口，该S 16个SRS端口关联S 16个天线端口，该S 17个SRS端口关联S 17个天线端口，该S 18个SRS端口关联S 18个天线端口，该S 6个天线端口，该S 15个天线端口，该S 16个天线端口和该S 18个天线端口不同，且S 15＝S 16＝S 17＝S 18。
以下，结合配置10，说明实施例2-3的具体实现方式。
配置10：M 2＝1，N 2＝4，S 15＝S 16＝S 17＝S 18＝3。
即，SRS资源集0中的第一个SRS资源、第二个SRS资源、第三个SRS资源和第四个SRS资源均包括3个SRS端口。
基于该配置10，各个发送通道端口的功率相同，不会存在端口的功率不一致问题。
图12是基于配置10的发送通道、接收通道和SRS资源的对应关系示意图。
如图12所示，SRS资源0、SRS资源1、SRS资源2和SRS资源3包括的SRS端口数均为3。
作为一种实现方式，发送通道端口、接收通道端口和SRS资源的对应关系如表10所示。
表10
端口\资源 SRS资源0 SRS资源1 SRS资源2 SRS资源3
TX0 AP0 AP1 AP0 AP0
TX1 AP1 AP2 AP2 AP1
TX2 AP2 AP3 AP3 AP3
在该配置10中，SRS资源之间需要预留至少一个符号的保护间隔。
应理解，图12和表10中的SRS资源和接收通道端口的关联关系仅为示例，SRS资源集中的SRS资源和接收通道端口也可以有其他的对应关系，只要保证每个SRS资源关联到不同的接收通道端口，并且所有SRS资源可以关联到所有的天线端口即可，或者说，每个天线端口至少关联一个SRS资源即可。
作为另一种实现方式，发送通道端口、接收通道端口和SRS资源的对应关系如表11所示。
表11
端口\资源 SRS资源0 SRS资源1 SRS资源2 SRS资源3
TX0 AP0 AP0 AP0 AP1
TX1 AP1 AP1 AP2 AP2
TX2 AP2 AP3 AP3 AP3
相对于表10中的关联关系，采用表11中的关联关系可以减少两次SRS资源之间从SRS端口到天线端口的变化，降低终端设备实现的复杂度，有利于终端设备内部器件的部署。例如，SRS资源0和SRS资源1，只有TX2对应的天线端口由AP2切换到AP3。
实施例3：
在该实施例3中，终端设备支持第三SRS天线切换能力，即终端设备支持的发送天线数为3，接收天线数为8。
此情况下，该SRS天线切换的配置信息包括M 3个SRS资源集，每个SRS资源集包括N 3个SRS资源，该N 3个SRS资源所占用的时域位置不同，其中，该M 3为正整数，该N 3为正整数。
即每个SRS资源集包括的SRS资源数可以相同。
在另一些实施例中，M 3大于1，M 3个SRS资源集中的每个SRS资源集包括的SRS资源数也可以不同，或者，M 3个SRS资源集中存在至少两个SRS资源集包括的SRS资源数不同。
例如，M 3个SRS资源集包括第一SRS资源集和第二SRS资源集，第一SRS资源集包括的SRS资源数和第二SRS集包括的SRS资源数不同，可选地，M 3个SRS资源集还可以包括第三SRS资源集，第三SRS资源集包括的SRS资源集与第一SRS资源集包括的SRS资源集可以相同，或者也可以不同。
以下以每个SRS资源集包括相同数量的SRS资源为例进行说明，但本申请并不限于此。
在一些实施例中，当M 3大于1时，每个SRS资源集的类型各不相同，或者，M 3个SRS资源集的类型都是“非周期”。
例如，M 3＝3，3个SRS资源集的类型分别为“周期”，“semi-persistent”，“非周期”。，即，第一个SRS资源集中的资源为周期配置的，第二个SRS资源集中的资源为半静态配置的，第三个SRS资源集中的资源为非周期调度的
再例如，M 3＝3，3个SRS资源集的类型都为“非周期”。即，第一个SRS资源集中的资源，第二个SRS资源集中的资源，第三个SRS资源集中的资源都是非周期调度的。
在实施例3中，M 3个SRS资源集共包括K3个SRS资源，该K3个SRS资源中的每个SRS资源包括至少一个SRS端口，该至少一个SRS端口中的每个SRS端口关联一个天线端口。将该K3个SRS资源包括的SRS端口数之和记为P3，即K3个SRS资源共包括P3个SRS端口，该P3个SRS端口关联的天线端口的数量之和大于或等于8。
在一些实施例中，M 3个SRS资源集共包括K3个SRS资源，K3个SRS资源共包括P3个SRS端口，该P3个SRS端口关联P32个天线端口，其中，该P3个天线端口包括所有的天线端口。即基于该P3个SRS资源进行天线切换有利于遍历所有的天线端口，获取全面的下行信道信息。
应理解，在该实施例3中，该K3个SRS资源中的任意两个SRS资源包括的SRS端口关联的天线端口不同，具体说明参考实施例1中的相关说明，为了简洁，这里不再赘述。
因此，在实施例3，网络设备通过配置至少一个SRS资源集，每个SRS资源集包括N 3个SRS资 源，N 3个SRS资源中的每个SRS资源包括至少一个SRS端口，至少一个SRS端口中的每个SRS端口关联到一个天线端口，N 3个SRS资源包括的所有的SRS端口关联不同的天线端口，并且所有的SRS资源包括的SRS端口可以关联所有的天线端口，例如，3个SRS资源包括的所有SRS端口关联8个天线端口，或者说，每个天线端口都可以关联到至少一个SRS资源，这样，终端设备根据该配置信息发送SRS，可遍历所有的天线端口，从而可以获得完整的下行信道信息。
可选地，在该实施例3中，M 3个SRS资源集包括的SRS资源的总个数不超过第三阈值，可选地，第三阈值可以为8。
以下，结合实施例3-1至实施例3-2，说明SRS天线切换的配置信息的典型实现，但本申请并不限于此。
实施例3-1：M 3为1或2或3，N 3为3或2或1。
在一些实施例中，M 3个SRS资源集中的每个SRS资源集包括的SRS资源数相同，例如，M 3＝2，N 3＝3，2或1，又例如，M 3＝3，N 3＝2或1等。
以M 3＝1，N 3＝3为例，该N 3个SRS资源中的索引为0的SRS资源包括S 19个SRS端口，该N 3个SRS资源中的索引为1的SRS资源包括S 20个SRS端口，该N 3个SRS资源中的索引为2的SRS资源包括S 21个SRS端口，其中，该S 19个SRS端口关联S 19个天线端口，该S 20个SRS端口关联S 20个天线端口，该S 21个SRS端口关联S 21个天线端口，该S 19个天线端口，该S 20个天线端口和该S 21个天线端口不同，且S 19+S 20+S 21＝8。
即，可以配置1个，2个或3个SRS资源集，每个SRS资源集包括3个SRS资源，每个SRS资源包括的SRS端口关联不同的天线端口，并且这两个SRS资源包括的SRS端口可以关联到所有的天线端口，即8个天线端口，或者，每个天线端口都可以关联到至少一个SRS资源，这样，通过发送三次SRS，可遍历所有的天线端口，从而可以获得所有下行信道的质量信息。
应理解，该S 19个天线端口，该S 20个天线端口和该S 21个天线端口不同，包括：该S 19个天线端口，该S 20个天线端口和该S 21个天线端口中的任意两组天线端口至少部分不同，或者，任意两组天线端口至少部分不重叠，具体含义参考前述实施例中的相关说明，为了简洁，这里不再赘述。
在一些实施例中，M 3个SRS资源集中的每个SRS资源集包括的SRS资源数也可以不同，例如，M 3＝2，索引为0的SRS资源集包括A9个SRS资源，索引为1的SRS资源集包括A10个SRS资源，A9+A6＝3，例如，A9＝2，A10＝1，或A9＝1，A10＝2。也可以理解为，M 3个SRS资源集中共包括3个SRS资源。以A9＝2，A10＝1为例，索引为0的SRS资源集中的索引为0的SRS资源包括S 19个SRS端口，索引为0的SRS资源集中的索引为1的SRS资源包括S 20个SRS端口，索引为1的SRS资源集中的索引为0的SRS资源包括S 14个SRS端口，其中，该S 19个SRS端口关联S 19个天线端口，该S 20个SRS端口关联S 20个天线端口，该S 21个SRS端口关联S 21个天线端口，该S 19个天线端口，该S 20个天线端口和该S 21个天线端口不同，且S 19+S 20+S 21＝8。
以下，结合配置11，说明实施例3-1的具体实现方式。
配置11：M 3＝1，N 3＝3，S 19＝3，S 20＝3，S 21＝2。
即，SRS资源集中的第一个SRS资源包括3个SRS端口，第二个SRS资源包括3个SRS端口，第三个SRS资源包括2个SRS端口。
图13是基于配置11的发送通道、接收通道和SRS资源的对应关系示意图。其中，图13中，发送通道对应的端口号从左向右依次为0,1,2，即TX0～TX2，接收通道对应的端口号从左向右为0,1,2,3,4,5,6,7，即AP0～AP7。
如图13所示，SRS资源集中的SRS资源0包括的SRS端口数为3，SRS资源1包括的SRS端口数为3，SRS资源2包括的SRS端口数为2。
作为一种实现方式，发送通道端口、接收通道端口和SRS资源的对应关系如表12所示。
表12
端口\资源 SRS资源0 SRS资源1 SRS资源2
TX0 AP0 AP3 AP6
TX1 AP1 AP4 AP7
TX2 AP2 AP5  
即SRS资源集0中的SRS资源0包括的SRS端口关联天线端口0～天线端口2，SRS资源1包括的SRS端口关联天线端口3～天线端口5，SRS资源2包括的SRS端口关联天线端口6～天线端口7，即这三个SRS资源包括SRS端口可以关联所有的天线端口，这样，发送三次SRS即可获取完整的下行信道信息，具体地，可以在一个时隙内完成天线切换。
可替换地，发送通道端口、接收通道端口和SRS资源的关联关系也可以与表12不同，本申请并不限于此。例如，SRS资源集0中的SRS资源2包括的SRS端口可以是发送通道端口TX1和TX2， 该SRS端口关联天线端口6和天线端口7。
实施例3-2：M 3小于或等于8且M 3不等于1，N 3小于或等于7。
在一些实施例中，M 3个SRS资源集中的每个SRS资源集包括的SRS资源数相同，例如，M 3＝2，N 3＝4等。
以M 3＝2，N 3＝4为例，该索引为0的SRS资源集中的索引为0的SRS资源包括S 22个SRS端口，该索引为0的SRS资源集中的索引为1的SRS资源包括S 23个SRS端口，该索引为0的SRS资源集中的索引为2的SRS资源包括S 24个SRS端口，该索引为0的SRS资源集中的索引为3的SRS资源包括S 25个SRS端口，该索引为1的SRS资源集中的索引为0的SRS资源包括S 26个SRS端口，该索引为1的SRS资源集中的索引为1的SRS资源包括S 27个SRS端口，该索引为1的SRS资源集中的索引为2的SRS资源包括S 28个SRS端口，该索引为1的SRS资源集中的索引为3的SRS资源包括S 29个SRS端口，其中，该S 22个SRS端口关联S 22个天线端口，该S 23个SRS端口关联S 23个天线端口，该S 24个SRS端口关联S 24个天线端口，该S 25个SRS端口关联S 25个天线端口，该S 26个SRS端口关联S 26个天线端口，该S 27个SRS端口关联S 27个天线端口，该S 28个SRS端口关联S 28个天线端口，该S 29个SRS端口关联S 29个天线端口，该S 22个天线端口、该S 23个天线端口、该S 24个天线端口、该S 25个天线端口、该S 26个天线端口、该S 27个天线端口、该S 28个天线端口和该S 29个天线端口不同，且S 22＝S 23＝S 24＝S 25＝S 26＝S 27＝S 28＝S 29。
即，可以配置多个SRS资源集，每个SRS资源集包括N 3个SRS资源，每个SRS资源包括的SRS端口数相同，但是关联到不同的天线端口，并且这两个SRS资源包括的SRS端口可以关联到所有的天线端口，即8个天线端口，或者，每个天线端口都可以关联到至少一个SRS资源，这样，通过发送N 3次SRS，即可遍历所有的天线端口，从而可以获得所有下行信道的质量信息，同时减少SRS资源与其他上行传输发生冲突的概率。
应理解，该S 22个天线端口、该S 23个天线端口、该S 24个天线端口、该S 25个天线端口、该S 26个天线端口、该S 27个天线端口、该S 28个天线端口和该S 29个天线端口不同可以指该S 22个天线端口、该S 23个天线端口、该S 24个天线端口、该S 25个天线端口、该S 26个天线端口、该S 27个天线端口、该S 28个天线端口和该S 29个天线端口不同中的任意两组天线端口不同，具体实现参考实施例1中的相关说明，为了简洁，这里不再赘述。以下，结合配置12，说明实施例3-2的具体实现方式。
配置12：M 3＝2，N 3＝4每个SRS资源包括的SRS端口数均为3，即S 22＝S 23＝S 24＝S 25＝S 26＝S 27＝S 28＝S 29＝3。
作为一种实现方式，发送通道端口、接收通道端口和SRS资源的对应关系如表13所示。
表13
Figure PCTCN2021122199-appb-000003
应理解，表13中的发送通道端口、接收通道端口和SRS资源的关联关系仅为示例，发送通道端口、接收通道端口和SRS资源也可以有其他的对应关系，只要保证每个SRS资源包括的SRS端口关联到不同的接收通道端口，并且所有SRS资源包括的SRS端口可以关联到所有的天线端口即可，或者说，每个天线端口至少关联一个SRS资源即可。
可替换地，发送通道端口、接收通道端口和SRS资源的关联关系也可以如表14所示，但本申请并不限于此。相对于表13中的关联关系，采用表14中的关联关系可以减少两次SRS资源之间从SRS端口到天线端口的变化，降低终端设备实现的复杂度，有利于终端设备内部器件的部署。
