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。
本公开实施例提供的SRS触发方法可应用于图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，网络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。其中，在5G NR系统中，可以配置上行SRS，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。
最新的标准版本17(R17)中，定义终端可以在任意一个符号上发送SRS，SRS长度也可以最大传输14个符号。SRS资源集合可以配置不同的功能(usage)。例如，可以包括用于波束管理的SRS，基于码本传输的SRS，基于非码本传输的SRS，以及用于天线切换的SRS。
在标准版本16(Rel-16)中，非周期SRS由物理下行控制信道(physical downlink control channel，PDCCH)上调度下行控制信息(downlink control information，DCI)中的SRS请求指示域触发。
其中，SRS码点(codepoint)用于表示要传输的SRS资源集合，不同功能的SRS资源集合可以对应相同的码点并同时由一个SRS请求指示DCI触发。例如，码点01对应触发SRS资源集合1，码点10对应触发SRS资源集合2，码点11对应触发SRS资源集合3。
在R17中，支持SRS灵活增强方法。R17的SRS灵活增强方法定义为基于可用时隙的DCI灵活指示方案。具体SRS的触发是基于原来的半静态时隙偏移基础上增加了DCI指示的动态时隙偏置，该新引入的DCI指示域用于指示在RRC配置的多个时隙偏置中的具体偏移值。
在R17的SRS增强中，SRS的灵活触发在R15/16配置的灵活触发偏移(legacy triggering offset)＝K指示的参考时隙基础上，通过DCI进一步指示RRC配置的触发偏置(triggering  offset)集合中的一个t值来实现，t用于指示终端的可用时隙。不同的SRS资源集合的K和t值独立配置，t值最多可以由RRC配置4个可选值。图3示出了本公开一示例性实施例中的SRS灵活触发示意图。参阅图3所示，DCI触发SRS集合，并在DCI中指示K＝3，故可以确定参考时隙(reference slot)为接收到DCI指令后的第3个时隙，即图3中标示1处。故，基于参考时隙可以在可用时隙中确定该SRS资源集合的实际可用时隙。图3中标示出的1、2、3、4、5对应位置为实际可用时隙。进一步的，通过DCI或RRC指示触发偏置集合中的t值。比如，指示t＝1，则指示选用偏移值集合中的第1个偏移值对应的时隙作为触发时隙。假设本公开实施例中图3中标示为1处的时隙，作为触发时隙，偏移值集合中的第1个偏移值为1(从0开始计数)，则终端在可用时隙中选择slot t+1＝2的时隙作为实际发送时隙触发SRS集合的传输。SRS灵活触发方式最大限度的兼容了已有终端的实现方式，同时实现了SRS的相对灵活的触发。该方案提高了触发A-SRS(非周期探测参考信号)的灵活性，同时确保gNB等网络设备和终端之间行为的一致，以确定依赖RRC配置的可用时隙，同时不考虑任何动态事件。
然而，在确定的可用时隙中进行SRS资源集合的触发时，在实际可用时隙中可能会出现资源冲突。
图4示出了本公开一示例性实施例中示出的一种在实际可用时隙中出现资源冲突的示意图。参阅图4所示，D表示下行可用时隙，U表示上行可用时隙。假设针对上行，配置SRS资源集合#1以及SRS资源集合#2这两个SRS资源集合。其中，SRS资源集合#1包括1个SRS资源，SRS资源集合#2包括2个SRS资源。SRS资源集合#1以及SRS资源集合#2参考时隙相同(第三个时隙)，则SRS资源集合#1以及SRS资源集合#2的上行实际可用时隙为编号为3、4、7、8对应的时隙。但是DCI激活对于SRS资源集合#1(包含1个SRS资源)，指示时隙偏移t＝1的触发时隙(编号为4的时隙)，SRS资源集合#1的实际发送时隙为编号为4的时隙。对于SRS资源集合#2(包含2个SRS资源)，指示时隙偏移t＝0的触发时隙(编号为3的时隙)。由于SRS资源集合#2包含2个SRS资源，故虽然指示的时隙偏移为0，但是两个SRS资源占用两个时隙，故SRS资源集合#2实际发送时隙为编号为3和4的时隙。SRS资源集合#1实际发送时隙与SRS资源集合#2实际发送时隙发生冲突，即在编号为4的时隙中会出现资源冲突。故，当一个DCI同时触发多个不同的SRS资源集合时，如何确定每个SRS资源集合的实际可用时隙，以避免资源碰撞是需要解决的问题。
本公开实施例提供一种SRS触发方法，在该SRS触发方法中，触发时隙满足使多个SRS资源集合中各SRS资源集合的实际发送时隙不同，进而避免在实际发送时隙中出现资 源冲突。
图5是根据一示例性实施例示出的一种SRS触发方法的流程图，SRS触发方法可以单独被执行，也可以结合其他实施例一同被执行。如图5所示，SRS触发方法用于终端中，包括以下步骤。
在步骤S11中，分别为同一个终端触发的多个SRS资源集合中各SRS资源集合确定实际可用时隙以及触发时隙，触发时隙满足使多个SRS资源集合中各SRS资源集合的实际发送时隙不同。
本公开实施例中，从参考时隙位置开始基于半静态配置，确定实际可用时隙。例如，可以通过RRC半静态配置，确定参考时隙位置以及实际触发时隙。实际触发时隙可以通过DCI在RRC半静态配置的触发时隙的可选时隙偏置中指定的具体值确定。例如，可以通过DCI codepoint指示。
本公开实施例中，触发时隙可以理解为是指示触发偏置集合中第几个t值对应的时隙。即，触发时隙是t值实际指示的时隙。
本公开实施例中，可以基于触发时隙在多个SRS资源集合中各SRS资源集合对应的实际可用时隙中确定实际发送时隙。多个SRS资源集合中各SRS资源集合的实际发送时隙不同。
本公开实施例中，在进行SRS触发时，为使多个SRS资源集合中各SRS资源集合的实际发送时隙不同，可以基于SRS资源集合标识进行发送时隙的确定。例如，可以按照SRS资源集合标识的优先级，顺序进行各个SRS资源集合的实际发送时隙确定，并且，优先级在后的SRS资源集合使用与优先级在前的SRS资源集合的实际发送时隙不同的时隙，以使多个SRS资源集合中各SRS资源集合的实际发送时隙不同。
以图11为例，对本公开实施例上述进行SRS触发的过程进行说明。图11示出了本公开一示例性实施例中示出的一种多个SRS资源集合中各SRS资源集合的实际发送时隙不同的示意图。参阅图11所示，假设配置终端上行可用时隙为图11中编号为3、4、7和8对应的时隙。图11中，对于SRS资源集合#1和SRS资源集合#2的参考时隙位置均为第3个时隙。故，对于SRS资源集合#1和SRS资源集合#2的实际可用时隙为编号为3、4、7和8对应的时隙。SRS资源集合#1的优先级高于SRS资源集合#2的优先级。在进行SRS资源集合#1的实际发送时隙确定时，SRS资源集合#1的触发时隙为t＝1所指示的编号为4的时隙，SRS资源集合#1的实际发送时隙为编号为4的时隙。在进行SRS资源集合#2的实际发送时隙确定时，SRS资源集合#2的触发时隙配置为t＝0的编号为3的时隙，SRS资源集合#2中的第一个SRS资源可以使用编号为3的时隙作为实际发送时隙，但由于不能 与SRS资源集合#1的实际发送时隙相同，故可将SRS资源集合#2中的第二个SRS资源的实际发送时隙确定为编号为7的时隙。SRS资源集合#1和SRS资源集合#2之间不存在相同的时隙，故避免出现资源冲突。
本公开实施例中，分别为同一个终端触发的多个SRS资源集合中各SRS资源集合按照不同规则确定实际可用时隙以及触发时隙，多个SRS资源集合中各SRS资源集合的实际发送时隙不同，进而避免在实际发送时隙中出现资源冲突。
一种实施方式中，同一个终端触发的多个SRS资源集合中各SRS资源集合对应的实际可用时隙以及触发时隙可以是由网络设备配置的。网络设备配置多个SRS资源集合中各SRS资源集合对应的实际可用时隙以及触发时隙，保证多个SRS资源集合中各SRS资源集合的实际发送时隙不同，进而避免出现实际发送时隙的资源冲突。
图6是根据一示例性实施例示出的一种SRS触发方法的流程图，SRS触发方法可以单独被执行，也可以结合其他实施例一同被执行。如图6所示，SRS触发方法用于终端中，包括以下步骤。
在步骤S21中，获取触发多个SRS资源集合中各个SRS资源集合的配置信息，其中，配置信息包括网络信令配置的参考时隙信息，时隙偏移值候选集合以及时隙偏移指示。
本公开实施例中，终端获取触发多个SRS资源集合中各个SRS资源集合的配置信息，基于该配置信息中包括的参考时隙信息，时隙偏移值候选集合以及时隙偏移指示，确定各个SRS资源集合的实际可用时隙以及触发时隙。
本公开实施例中，终端针对多个SRS资源集合中各个SRS资源集合，可以分别独立确定每个SRS资源集合的触发时隙以及各自的实际可用时隙，并在实际可用时隙中最终确定的实际发送时隙不同。
另一种实施方式中，终端可以按照网络信令指示的优先级应用规则或协议预定义的优先级应用规则，分别确定多个SRS资源集合中各SRS资源集合的实际可用时隙和实际发送时隙。
图7是根据一示例性实施例示出的一种SRS触发方法的流程图，SRS触发方法可以单独被执行，也可以结合其他实施例一同被执行。如图7所示，SRS触发方法用于终端中，包括以下步骤。
在步骤S31中，按照网络信令指示的优先级应用规则或协议预定义的优先级应用规则，分别确定多个SRS资源集合中各SRS资源集合的实际可用时隙和实际发送时隙。
其中，可以理解的是，本公开实施例中，多个SRS资源集合为终端在一个或多个载波上激活的SRS资源集合，或者在同一载波上激活的SRS资源集合。其中，该同一载波可 以理解为是和DCI(即PDCCH)所在载波或者所指示的载波相同的载波。
其中，指示优先级应用规则的网络信令包括RRC信令、或媒体接入控制(Medium Access Control，MAC)信令、或DCI信令.
一种实施方式中，优先级应用规则基于以下之一或组合确定：
SRS资源集合对应的功能、SRS资源集合对应的载波标识、SRS资源集合标识、SRS资源集合对应的实际触发时间等。
一示例中，本公开实施例中，可以基于SRS资源集合对应的功能进行实际可用时隙的确定。比如，在发生资源冲突的时隙内，优先映射优先级高的功能的SRS资源集合。比如天线切换的SRS资源集合优先级最高，波束管理的SRS资源集合优先级最低。在天线切换的SRS资源集合和波束管理的SRS资源集合在某一时隙发生资源冲突时，需要优先将该时隙确定为天线切换的SRS资源集合的实际可用时隙。
又一示例中，本公开实施例中，可以基于SRS资源集合对应的载波标识进行实际可用时隙的确定。比如，在发生资源冲突的时隙内，优先映射优先级高的载波标识的SRS资源集合。比如载波标识最小的载波上触发的SRS资源集合优先级最高，载波标识最大的载波上触发的SRS资源集合优先级最低。在载波标识最小的载波上触发的SRS资源集合和载波标识最大的载波上触发的SRS资源集合在某一时隙发生资源冲突时，需要优先将该时隙确定为载波标识最小的载波上触发的SRS资源集合的实际可用时隙。
又一示例中，本公开实施例中，可以基于SRS资源集合标识进行实际可用时隙的确定。比如，在发生资源冲突的时隙内，优先映射优先级高的SRS资源集合标识的SRS资源集合。比如SRS资源集合标识最小的SRS资源集合优先级最高，SRS资源集合标识最大的SRS资源集合优先级最低。在SRS资源集合标识最小的SRS资源集合和SRS资源集合标识最大的SRS资源集合在某一时隙发生资源冲突时，需要优先将该时隙确定为SRS资源集合标识最小的SRS资源集合的实际可用时隙。
又一示例中，本公开实施例中，可以基于SRS资源集合对应参考可用时隙的时间进行实际可用时隙的确定。比如，在发生资源冲突的时隙内，优先映射优先级高的参考可用时隙的时间的SRS资源集合。比如触发时隙在前的SRS资源集合优先级高于触发时隙在后的SRS资源集合优先级。在触发时隙在前的SRS资源集合和触发时隙在后的SRS资源集合在某一时隙发生资源冲突时，需要优先将该时隙确定为触发时隙在前的SRS资源集合的实际可用时隙。
又一示例中，本公开实施例中，可以基于SRS资源集合占用的符号数进行实际可用时隙的确定。比如，在发生资源冲突的时隙内，优先映射优先级高的SRS资源集合占用的符 号数的SRS资源集合。比如SRS资源占用的符号数较少的SRS资源集合优先级高于SRS资源占用的符号数较多的SRS资源集合优先级。在SRS资源占用的符号数较少的SRS资源集合和SRS资源占用的符号数较多的SRS资源集合在某一时隙发生资源冲突时，需要优先将该时隙确定为SRS资源占用的符号数较少的SRS资源集合的实际可用时隙。
可以理解的是，本公开实施例中终端基于优先级应用规则进行实际可用时隙确定时，终端可以按照优先级对应的SRS资源集合顺序来确定实际可用时隙，后续确定的实际可用时隙不包含已确定的SRS资源集合中的实际发送时隙。
本公开实施例提供的SRS触发方法，对于一个DCI同时触发多个SRS资源集合的情况，通过对于触发时可用时隙的选择，改变实际可用时隙配置，从而降低实际发送时隙中SRS触发碰撞，保证系统优先的SRS发送。
基于相同的构思，本公开实施例还提供一种由网络设备执行的SRS触发方法。
图8是根据一示例性实施例示出的一种SRS触发方法的流程图，SRS触发方法可以单独被执行，也可以结合其他实施例一同被执行。如图8所示，SRS触发方法用于网络设备中，包括以下步骤。
在步骤S41中，确定为同一个终端触发的多个SRS资源集合中各SRS资源集合分配的实际可用时隙以及触发时隙，触发时隙满足使多个SRS资源集合中各SRS资源集合的实际发送时隙不同。
在步骤S42中，发送实际可用时隙以及触发时隙。
本公开实施例中，网络设备基于确定的实际可用时隙以及触发时隙，发送实际可用时隙以及触发时隙给终端，使终端触发的多个SRS资源集合中各SRS资源集合的实际发送时隙不同。
图9是根据一示例性实施例示出的一种SRS触发方法的流程图，SRS触发方法可以单独被执行，也可以结合其他实施例一同被执行。如图9所示，SRS触发方法用于网络设备中，包括以下步骤。
在步骤S51中，发送触发多个SRS资源集合中各个SRS资源集合的配置信息，其中，配置信息包括网络信令配置的参考时隙信息，时隙偏移值候选集合以及时隙偏移指示。
图10是根据一示例性实施例示出的一种SRS触发方法的流程图，SRS触发方法可以单独被执行，也可以结合其他实施例一同被执行。如图10所示，SRS触发方法用于网络设备中，包括以下步骤。
在步骤S52中，发送网络信令，网络信令用于指示优先级应用规则，优先级应用规则用于分别确定多个SRS资源集合中各SRS资源集合的实际可用时隙和实际发送时隙。
一种实施方式中，网络信令包括RRC信令、或MAC信令、或DCI信令；
一种实施方式中，优先级应用规则基于以下之一或组合确定：
SRS资源集合对应的功能、SRS资源集合对应的载波标识、SRS资源集合标识、SRS资源集合对应参考可用时隙的时间、以及SRS资源集合占用的符号数。
一种实施方式中，多个SRS资源集合为终端一个或多个载波上激活的SRS资源集合，或者在同一载波上激活的SRS资源集合。
可以理解的是，本公开实施例中应用于网络设备的SRS触发方法，与应用于终端的SRS触发方法具有相类似之处，故，对于应用于网络设备的SRS触发方法描述不够详尽之处，可以参阅应用于终端的SRS触发方法的相关内容，在此不再详述。

本公开实施例中提供的SRS触发方法，确定的实际可用时隙以及触发时隙，满足使同一终端触发的多个SRS资源集合中各SRS资源集合的实际发送时隙不同。
本公开实施例中，在进行SRS触发时，为使多个SRS资源集合中各SRS资源集合的实际发送时隙不同，可以基于SRS资源集合标识进行发送时隙的确定。例如，可以按照SRS资源集合标识的优先级，顺序进行各个SRS资源集合的实际发送时隙确定，并且，优先级在后的SRS资源集合使用与优先级在前的SRS资源集合的实际发送时隙不同的时隙，以使多个SRS资源集合中各SRS资源集合的实际发送时隙不同。
以图11为例，对本公开实施例上述进行SRS触发的过程进行说明。图11示出了本公开一示例性实施例中示出的一种多个SRS资源集合中各SRS资源集合的实际发送时隙不同的示意图。参阅图11所示，假设配置终端上行可用时隙为图11中编号为3、4、7和8对应的时隙。图11中，对于SRS资源集合#1和SRS资源集合#2的参考时隙位置均为第3个时隙。故，对于SRS资源集合#1和SRS资源集合#2的实际可用时隙为编号为3、4、7和8对应的时隙。SRS资源集合#1的优先级高于SRS资源集合#2的优先级。在进行SRS资源集合#1的实际发送时隙确定时，SRS资源集合#1的触发时隙为t＝1所指示的编号为4的时隙，SRS资源集合#1的实际发送时隙为编号为4的时隙。在进行SRS资源集合#2的实际发送时隙确定时，SRS资源集合#2的触发时隙配置为t＝0的编号为3的时隙，SRS资源集合#2中的第一个SRS资源可以使用编号为3的时隙作为实际发送时隙，但由于不能与SRS资源集合#1的实际发送时隙相同，故可将SRS资源集合#2中的第二个SRS资源的实际发送时隙确定为编号为7的时隙。SRS资源集合#1和SRS资源集合#2之间不存在相 同的时隙，故避免出现资源冲突。
需要说明的是，本领域内技术人员可以理解，本公开实施例上述涉及的各种实施方式/实施例中可以配合前述的实施例使用，也可以是独立使用。无论是单独使用还是配合前述的实施例一起使用，其实现原理类似。本公开实施中，部分实施例中是以一起使用的实施方式进行说明的。当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
