具体实施方式
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。
本公开实施例提供的用于天线切换配置的SRS发送方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括网络设备和终端。终端通过无线资源与网络设备相连接，并进行数据传输。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可 包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端进行通信。此外，当为车联网(V2X)通信系统时，网络设备还可以是车载设备。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、客户前置设备(Customer Premise Equipment，CPE)，口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
相关技术中，在发射端和接收端分别使用多个发射天线和接收天线，使信号通过发射端与接收端的多个天线传送和接收。通过多个天线实现多发多收，在不增加频谱资源和天线发射功率的情况下，可以成倍的提高系统信道容量，并提高数据吞吐量和信噪比,从而 提高系统性能并改善通信质量。
为了支持各种终端收发能力下能够通过信道，有效的获取到下行信息，通信系统中针对终端设置不同的天线切换配置。R15/16定义的终端的天线切换能力可以分为接收天线数量和发射天线数量相同(即，T＝R)，以及接收天线多于发射天线(即，R>T)。相关技术中，目前协议支持的T＝R的情况，终端天线切换能力主要有一发一收(1T1R)、两发两收(2T2R)、四发四收(4T4R)。R>T的情况，即接收天线多于发射天线主要有几种情况：一发两收(1T2R)、一发四收(1T4R)、两发四收(2T4R)。
其中，R15中终端支持的天线切换能力为：1T2R，1T4R，2T4R，1T4R-2T4R，1T1R，2T2R，4T4R。
R16中终端支持的天线切换能力为：1T1R-1T2R，1T1R-1T2R-1T4R，1T1R-1T2R-2T2R-2T4R，1T1R-1T2R-2T2R-1T4R-2T4R，1T1R-2T2R,1T1R-2T2R-4T4R。
目前在R17的研究中，考虑终端的天线数有进一步增加的需求，因此会进一步增加天线数目到最大6天线或者最大8天线。目前定义的典型的天线配置为{1T6R，1T8R，2T6R，2T8R，[4T6R]，4T8R}，如下表1所示：
表1：最多到8天线的SRS天线切换组合
Tx\Rx 6Rx 8Rx
1T 1T6R 1T8R
2T 2T6R 2T8R
4T 4T6R 4T8R
相关技术中，配置用于天线切换配置的探测参考信号(Sounding Reference Signal，SRS)。其中，不同的天线切换配置对应不同的SRS。当前协议中支持的用于天线切换配置的SRS有如下几种情况：
(1)对于收发天线数相同(T＝R)终端，网络设备可以最多配置两个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。
(2)对于一发两收(1T2R)能力的终端，网络设备可以最多配置两个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。
(3)对于两发四收(2T4R)能力的终端，网络设备可以最多配置两个SRS资源集合，在一个集合中有两个SRS资源、每个SRS资源有两个端口。
(4)对于一发四收(1T4R)能力的终端，网络设备配置SRS资源需要特殊考虑，周期或半持续SRS资源最多只能配置一个资源集合，其中有4个SRS资源各有1个端口；为非周期SRS资源最多可以配置2个SRS资源集合、两个SRS资源集合里一共有4个SRS资源，而这4个资源在两个slot内发送且这4个资源由不同的物理天线发送。两个资源集 合可以每个集合各配置2个资源，或一个集合1个另一个集合3个资源，每个资源只有1端口。
在5G NR系统中，SRS资源的触发可以包括周期/半持续/非周期的SRS资源配置触发机制。
其中，周期的SRS(P-SRS)所有参数由高层信令配置，由高层信令进行配置后终端根据所配置的参数进行周期性发送。半持续的SRS(SP-SRS)所有参数也由高层信令配置，与周期探测参考信号(SRS)不同之处是，虽然相应参数已经被配置，但是终端在收到激活命令之前不能发送SRS。一旦被激活终端开始发送SRS，直到收到网络设备发送的去激活命令，停止发送SRS。SP-SRS的激活、去激活命令由MAC层发送也就是MAC CE命令。
非周期的SRS资源(AP-SRS)触发通过下行控制信令(Downlink Control Information，DCI)中的SRS request来触发，表2是具体的触发信令。
表2
Figure PCTCN2021120014-appb-000001
相关技术中，上行SRS可以是周期SRS、半持续SRS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配置，并包括端口数目、频域资源位置、时域资源位置、序列、序列循环偏移量等。在5G NR系统中，SRS在一个上行时隙的最多六个符号上映射，如图2所示，示出了时隙内SRS映射区域。
其中，网络设备为终端可以配置多个上行SRS集合，一个资源集合包含一个或者多个SRS资源。一个SRS资源可以在N个连续OFDM符号上，N可以占用1，2，4个符号。
R15/16NR系统中，支持基站等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。为了支持各种终端收发能力下gNB也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。
进一步的，为了适用当前业务或者场景，终端可能需要改变天线配置，例如从2T4R降低为1T4R或者2T2R，或者从2T2R改变为4T4R的情况，这时就需要进行天线切换配置的切换。
相关技术中终端进行天线切换配置的切换支持的如下天线切换能力：
发射端切换(Tx switching)：发射天线/发射天线端口动态切换，但是接收天线/接收天线端口不变化。也就是从xTyR切换到zTyR,x不等于z。比如，4T4R的终端切换到2T4R或者1T4R。
接收端切换(Rx switching)：接收天线/接收天线端口动态切换，但是发射天线/发射天线端口不变化。也就是从xTyR切换到xTzR,x不等于z。比如，1T4R的终端切换到1T2R或者1T1R。
Tx switching/Rx switching：同时支持发射天线/发射天线端口以及接收天线/接收天线端口的动态切换，即从xTyR切换到x’Ty’R，其中允许x，y同时不等于x’,y’。比如，4T4R的终端切换到1T2R或者1T1R。
R17的SRS增强中，终端接收天线数目会增加到6/8,需要天线切换的场景更多，对天线切换配置的动态改变有更强的需求。不同的切换方式在终端有不同的需求，对终端和网络有不同的影响。对于终端，考虑到不同的配置情况，目前主要考虑在Rx天线/端口切换实现动态的切换支持，例如对于1T4R的终端可以支持回退到1T2R或者1T1R。
然而，对于终端来讲，Tx switching也有较强的需求，比如，4T8R的终端可以通过关闭发射链路(Tx chain)来达到类似省电这样的需求，可以切换到2T8R或者1T8R。因此同样需要考虑发射天线/发射端口切换的实现方案。
本公开实施例提供一种用于天线切换配置的SRS发送方法，通过指示目标天线切换配置相关信息的指示信息，确定用于发送目标天线切换配置的目标SRS资源，并按照该目标SRS资源发送目标天线切换配置的SRS，实现天线切换配置的动态切换。
图3是根据一示例性实施例示出的一种用于天线切换配置的SRS发送方法的流程图，如图3所示，用于天线切换配置的SRS发送方法用于终端中，包括以下步骤。
在步骤S11中，获取指示信息，指示信息用于指示天线切换配置相关信息，天线切换配置相关信息包括以下之一或组合：目标天线切换配置对应SRS所使用的发射天线、目标天线切换配置对应SRS所使用的发射天线端口，目标天线切换配置，目标天线切换配置对应SRS资源。
在步骤S12中，基于指示信息，确定用于发送目标天线切换配置的目标SRS资源。
在步骤S13中，按照目标SRS资源，发送目标天线切换配置的SRS。
本公开实施例中，用于指示天线切换配置相关信息的指示信息，可以理解为是新引入得到指示信令(indicator)用于指示发射天线/发射天线端口切换所使用的天线切换配置对应SRS。或者该指示信息也可以理解为是指示发射天线/发射天线端口切换所使用的天线切换配置对应SRS发生变更的变更指示。
其中，本公开实施例中用于指示天线切换配置相关信息的指示信息可以包括如下至少一种：
媒体接入控制控制单元(media access control-control element，MAC CE)、下行控制信息(Downlink Control Information，DCI)、配置授权的下行控制信息(grant controller-DCI，GC-DCI)以及无线资源控制信息(Radio Resource Control，RRC)。
进一步的，本公开实施例中，目标天线切换配置对应的SRS包括周期性SRS、非周期性SRS以及半持续SRS中的一种或多种。
本公开实施例中，网络设备可以基于不同的SRS资源集合，指示终端发送用于天线切换配置的SRS。
本公开实施例一种实施方式中，网络为终端配置多个对应于不同天线切换配置的SRS资源集合，以下称为第一SRS资源集合。其中，终端可以在第一SRS资源集合中确定目标SRS资源集合，并在目标SRS资源集合中，基于指示信息，确定用于发送目标天线切换配置的目标SRS资源。其中，目标SRS资源集合中包括终端支持的天线切换配置对应的一个或多个SRS资源。每个天线切换配置对应的SRS资源集合包含一个或者多个第一SRS资源。
其中，网络为终端配置多个对应于不同天线切换配置的第一SRS资源集合的情况下，网络可以通过指示信息指示终端在多个终端上报并支持的天线切换能力中，基于当前配置的天线切换配置，进行向上/向下的调整情况。
本公开实施例可以基于终端支持的天线切换能力，指示目标天线切换配置。
一种实施方式中，终端支持的天线切换能力为支持发射天线切换，不支持接收天线切换，指示信息可以指示调整当前天线切换配置为目标天线切换配置对应SRS所使用的目标发射天线或目标发射天线端口。一示例中，对于支持Tx switching的终端，指示Tx支持端口的调整情况。例如，支持1、2、4端口的发送，终端当前使用2端口发送。若指示信息指示为1，则切换到4端口发送。若指示信息指示为0，则切换到1端口发送，实际对应天线切换配置的调整。
其中，可以理解的是，本公开实施例中指示信息所指示的发射天线可以包括一个发射天线，或者也可以包括多个发射天线的组合。本公开实施例中指示信息所指示的发射天线 端口可以包括一个发射天线端口，或者也可以包括多个发射天线端口的组合。
另一种实施方式中，终端支持的天线切换能力为支持发射天线和/或接收天线切换，指示信息可以包括如下至少一种方式：
方式1：指示信息指示目标天线切换配置对应SRS所使用的目标发射天线或目标发射天线端口。
一示例中，指示Tx支持的天线发射端口的调整情况，对应Rx保持不变。
方式2：指示信息指示目标天线切换配置。
一示例中，指示终端支持的天线切换配置。其中，Tx/Rx均可变。例如，支持t1r1-t2r2-t4r4天线切换能力的终端，当前配置为t2r2，可以通过信令指示调整，如指示1，则调整为4T对应的天线切换配置。
本公开实施例提供的用于天线切换配置的SRS发送方法中，可以通过指示信息指示目标天线切换配置对应的SRS生效，也可以是通过网络调度指示目标天线切换配置对应的SRS生效或切换BWP，以使终端发送目标天线切换配置对应的SRS。本公开实施例中，终端发送目标天线切换配置对应的SRS可以包括如下方式：
激活并发送目标天线切换配置对应的SRS。或者基于接收的RRC信令，确定并发送目标天线切换配置对应的SRS资源。或者切换至包括目标SRS资源的带宽部分，发送目标天线切换配置对应的SRS。
进一步的，本公开实施例中，终端还可以上报天线切换配置信息，以便于网络设备基于终端上报的天线切换配置信息，指示目标天线切换配置的相关信息。
一种实施方式中，终端上报的天线切换配置信息用于指示以下的一种或多种的组合：
终端期望的目标天线切换配置；终端期望的发送天线或发送天线端口配置；终端期望的SRS资源配置。
本公开实施例中，终端上报天线切换配置信息时，可以基于MAC CE、上行控制信息(Uplink Control Information，UCI)、配置授权的上行控制信息(grant controller-UCI，GC-UCI)以及RRC消息中的至少一种，上报天线切换配置信息。
可以理解的是，本公开上述基于网络配置的第一SRS资源集合实现天线切换配置的SRS发送的各实施例可以单独被执行，也可以是一个或多个实施例结合执行。
图4是根据一示例性实施例示出的一种用于天线切换配置的SRS发送方法的流程图，如图4所示，用于天线切换配置的SRS发送方法用于终端中，包括以下步骤。
在步骤S21中，上报天线切换配置信息。
在步骤S22中，获取指示信息，指示信息指示目标天线切换配置对应SRS所使用的目 标发射天线或目标发射天线端口；或者指示信息指示目标天线切换配置。
一种实施方式中，终端为支持发射天线切换的终端，指示信息用于指示调整当前天线切换配置为目标天线切换配置对应SRS所使用的目标发射天线或目标发射天线端口。
另一种实施方式中，终端为支持发射天线和/或接收天线切换的终端，指示信息指示目标天线切换配置对应SRS所使用的目标发射天线或目标发射天线端口；或者指示信息指示目标天线切换配置。
可以理解的是，本公开实施例中，终端获取的指示信息所指示的目标天线切换配置相关信息可以是基于步骤S21中终端上报的天线切换配置信息确定的。
进一步可以理解的是，本公开实施例中步骤S21为可选步骤。
在步骤S23中，在第一SRS资源集合中确定目标SRS资源集合，并在目标SRS资源集合中，基于指示信息，确定用于发送目标天线切换配置的目标SRS资源。
在步骤S24中，按照目标SRS资源，激活并发送目标天线切换配置对应的SRS；或者基于接收的RRC信令，确定并发送目标天线切换配置对应的SRS资源；或者切换至包括目标SRS资源的带宽部分，发送目标天线切换配置对应的SRS。
本公开实施例提供的用于天线切换配置的SRS发送方法，实现了对发射天线/发射天线端口的SRS配置切换，进而实现了发射端天线切换配置的动态切换。
本公开实施例另一种实施方式中，网络为终端配置包括终端支持的全部发射天线或发射端口的天线切换配置对应的SRS资源集合，或者网络为终端配置包括终端支持的多个不同天线切换配置对应的SRS资源集合，以下称为第二SRS资源集合。
一示例中，网络可以配置一个包含所有Tx chain对应的SRS资源的SRS资源集合。或者网络可以配置包括多个不同天线切换配置对应的SRS资源集合。
其中，终端在第二SRS资源集合中，确定目标SRS资源集合。第二SRS资源集合为包括终端支持的全部发射天线或发射端口的天线切换配置对应的SRS资源集合，或者第二SRS资源集合为终端支持的多个不同天线切换配置对应的SRS资源集合。终端在目标SRS资源集合中，基于指示信息，确定用于发送目标天线切换配置的目标SRS资源。
本公开实施例中，网络配置第二SRS资源集合的情况下，一方面，指示信息可以用于指示目标天线切换配置对应SRS所使用的目标发射天线或目标发射天线端口。另一方面，指示信息可以用于指示目标天线切换配置对应的SRS资源，其中，SRS资源属于一个或者多个SRS资源集合。
