Description

触发非周期SRS资源的方法和通信装置 技术领域
本申请涉及无线通信技术领域，更具体地，涉及一种触发非周期SRS资源的方法和通信装置。
背景技术
新空口(new radio,NR)作为一种新兴的无线电技术，其特有的性质可以在增强定位能力方面提供更多的价值，因此，NR定位成为第三代合作伙伴计划(the third generation partnership project,3GPP)标准的一个重要研究课题。目前，3GPP标准将NR定位技术分为三大部分，独立无线接入技术(radio access technology-independent,RAT-independent)技术、非独立无线接入技术(radio access technology-independent,RAT-dependent)，以及RAT-independent和RAT-dependent相结合的技术。其中，RAT-dependent指的是仅仅依靠无线接入技术或者蜂窝网的定位方法。RAT-independent代表除了蜂窝网技术的其它定位技术，例如，蓝牙、无线局域网(wireless local area network,WLAN)、全球导航卫星系统(global navigation satellite system,GNSS)以及惯性测量等方法。其中，RAT-dependent技术中涉及一种基于上行链路的定位技术。
在基于上行链路的定位技术中，主要是由网络侧对终端设备发送的用于定位的探测参考信号(sounding reference signal,SRS)资源进行测量，并根据测量结果对终端设备的位置进行估算。在目前的标准中，用于定位的非周期SRS资源是由基站发送的下行控制信息(downlink control information,DCI)中携带的SRS请求(SRS request)字段触发的。但是，由于通信场景的多样化，SRS请求字段除了触发用于定位的非周期SRS资源，还用于触发其它用途的SRS资源。例如，SRS请求字段的某些状态触发两种或两种以上用途的SRS资源，假设，被触发的非周期SRS资源中包括用于定位的非周期SRS资源，此时，终端设备除了发送被触发的其它用途的非周期SRS资源，即使终端设备或者网络侧没有定位需求，终端设备依然需要发送被触发的用于定位的SRS资源。这种不同用途的非周期SRS资源的触发耦合在一起的状况，会带来很多不利方面。例如，增加了终端设备的处理复杂度、造成终端设备的资源浪费，以及对其它终端设备造成干扰等。

应理解，第七方面中所述的“期望用途的非周期SRS资源”可以是期望与其它用途解耦的任意一种用途的非周期SRS资源。例如，目前标准中定义的SRS资源的用途包括用于码本传输、非码本传输、波束管理、天线切换以及定位共5种用途。所述“期望用途”可以是所述5种用途中的任意一种。换句话说，期望与其它用途解耦的用途，即是“期望用途”。
由此可知，通过第七方面的方法，可以实现任意用途的非周期SRS资源与其它用途的非周期SRS资源的解耦。因此，该方法不仅可以应用在触发定位用途的非周期SRS资源的场景下，使得定位用途的非周期SRS资源的触发不和其它用途的非周期SRS资源的触发耦合在一起，也可以应用于触发其它用途的非周期SRS资源的场景下。
例如，若网络侧需要触发终端设备发送用于波束管理的非周期SRS资源，则第七方面的方法中所述的“期望用途的非周期SRS资源”即为用于波束管理的非周期SRS资源。若网络侧需要触发终端设备发送用于码本传输的非周期SRS资源，则第七方面的方法中所述的“期望用途的非周期SRS资源”即为用于码本传输的非周期SRS资源。不再一一列举。
此外，如果非周期SRS资源的用途除了目前标准中定义的上述5种用途之外，新增了其它用途，本申请技术方案中的“期望用途”也可以是该新增的用途，不作限定。
第八方面，本申请还提供一种触发非周期SRS资源的方法，该方法包括：
终端设备接收来自于网络设备的MAC-CE信令，所述MAC-CE信令包含R个比特，所述R个比特中的每个比特唯一对应一种用途的非周期SRS资源集合，所述R个比特中的每个比特用于指示所对应的非周期SRS资源集合是否被激活，R为正整数；

可以理解，在第九方面的方法中，若网络侧需要将某种用途的非周期SRS资源集合的触发与其它用途的非周期SRS资源集合的触发解耦，只需要从所述P个组中选择仅包括期望用途而不包括其它用途的非周期SRS资源集合的组，并通过DCI触发即可。由此，也可以实现将期望用途的非周期SRS资源与其它用途的非周期SRS资源的触发解耦。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
参见图1，图1为基于上行链路的定位技术的一般流程。如图1，基于上行链路的定位技术，通常只需要基站侧对上行链路的参考信号进行测量，利用基于上行-观测到达时间差(uplink-observed time difference of arrival,UL-TDOA)技术和基于上行观测-到达角(uplink-angle of arrival,UL-AOA)技术。这些定位技术的实现基本都需要经过如下步骤：首先，服务基站向用户设备(user equipment,UE)指示发送上行参考信号的配置信息。UE在接收到基站的指示后开始发送SRS。服务基站和邻基站对接收到的SRS进行相关测量，例如，测量SRS的到达时间、到达角度或者参考信号接收功率(reference signal received power,RSRP)等。最后，基站将测量得到的结果上报给定位管理功能(location management function,LMF)，由LMF利用测量结果进行对UE的位置进行估算。
在上述定位过程中，最重要的过程是网络侧(例如，服务基站和邻基站)需要对UE发送的用于定位的SRS进行测量，以得到SRS的到达时间或到达角度，进而才能得出UE与基站的距离和方向，并估算UE的位置。对于UE来说，UE需要根据从基站接收的SRS的配置信息来发送SRS。SRS的配置信息通常可以包括SRS资源的带宽、周期、初始化值以及时频位置等。并且，基站还需要同时给UE配置多个SRS资源或资源集。这里，资源集是指由多个SRS资源组成的集合。
目前，用于定位的SRS资源支持周期、半静态和非周期配置。其中，周期SRS资源是指当高层无线资源控制(radio resource control,RRC)信令配置完SRS资源之后，UE就会按照配置的周期不断地发送SRS资源。其中，半静态SRS资源是指在RRC信令配置完SRS资源后，UE不会立即发送SRS资源，而是需要基站通过媒体介入控制单元(medium access control-control element,MAC-CE)信令激活之后，UE再以配置的周期不断地发送SRS资源，直到MAC-CE信令去激活后才停止发送。非周期SRS资源是指基站通过RRC信令配置完SRS资源之后，基站通过DCI来触发非周期SRS资源的发送，并且只发送一次。
需要说明的是，这里所说的SRS资源的时域行为(例如，周期、半静态或非周期)是在SRS资源集合的级别上配置的，即如果一个SRS资源集合被配置为周期的，那么该SRS资源集合中包含的所有SRS资源都是周期的。因此，本申请中提及的SRS资源是周期的，是指该SRS资源所属的SRS资源集合是周期的。
本申请主要涉及用于定位的非周期SRS资源的触发过程。
在目前的标准中，用于定位的非周期SRS资源的触发机制与版本15(Rel-15)的非周期SRS资源的触发机制是相同的，即，利用DCI format 0_1，format 0_2，format 1-1，format 1-2，format 2-3中的SRS请求(SRS request)字段来触发非周期的SRS资源是否发送。其中，SRS request字段(也称为SRS request域)的不同取值在DCI的各格式下所代表的含义如表1所示。
表1
Figure PCTCN2020084165-appb-000001
如表1所示，SRS request字段包括2个比特，如果使用DCI format 0_1,0_2，1-1，1-2来触发，并且所述2比特设置为“00”，表示不触发任何非周期SRS资源的发送。如果所述2比特设置为“01”，表示触发在SRS-config中把“aperiodicSRS-ResourceTrigger”字段设置为1的非周期SRS资源集。如果所述2比特设置为“10”，表示触发在SRS-config中把“aperiodicSRS-ResourceTrigger”字段设置为2的非周期SRS资源集。如果所述2比特设置为“11”，表示触发在SRS-config中把“aperiodicSRS-ResourceTrigger”字段设置为3的非周期SRS资源集。
如果使用DCI format 2_3来触发，需要分两种情况。在一种情况下，当高层参数SRS-TPC-PDCCH-Group设置为“type B”，则SRS request字段代表的含义以及触发机制与表1中DCI format 0_1、0_2、1_1、1_2中的相同。在另一种情况下，当高层参数SRS-TPC-PDCCH-Group设置为“type A”，且如果SRS request字段设置为“00”，仍表示不触发任何非周期SRS资源。如果SRS request字段设置为“01”，代表的是触发第一组服务小区中用作天线的非周期SRS(即，SRS-resource set for antenna Switching)以及用于定位的非周期SRS(即，SRS-resource set for positioning)。如果SRS request字段设置为“10”，代表的是触发第二组服务小区中用作天线的非周期SRS以及用于定位的非周期SRS。如果SRS request字段设置为“11”，代表的是触发第三组服务小区中用作天线的非周期SRS以及用于定位的非周期SRS。
可见，在目前标准的触发机制中，用于触发非周期SRS资源发送的SRS request字段包括2比特，总共可以表示4种状态，其中，“00”不触发任何非周期SRS资源，因而只有3个状态“01”，“10”和“11”用于触发非周期SRS资源。因此，SRS request字段最多可以分别触发3种用途的SRS资源。而目前，非周期SRS资源的用途除了用于定位，还包 括其它的用途，例如用于码本传输、用于非码本传输、用于波束管理、用于天线切换等。那么，基于上述触发机制，则SRS request字段如果用于触发上述5种状态，必然有一些状态触发了两种或两种以上用途的SRS资源。
这里需要说明的是，在非周期SRS资源的触发机制中，SRS资源是由RRC信令配置的，当UE进入连接态之后就从基站侧接收到了SRS资源的配置信息，后续只需要基站通过DCI激活。如果SRS request字段的一种状态触发了多种用途的SRS资源，当UE或者网络侧没有定位需求的情况下，用于触发其它用途的SRS资源的DCI可能同时触发了用于定位的非周期SRS资源的发送，在这种情况下，即使UE或者网络侧没有定位需求，UE依然需要发送被SRS request字段触发的用于定位的SRS资源。也即，按照目前标准的SRS request字段触发非周期SRS资源，必然出现不同用途的非周期SRS资源的触发耦合在一起的状况，这样会有很多不利方面。
为此，本申请提供一种解决方案，可以灵活地触发用于定位的非周期SRS资源，使得触发用于定位的非周期SRS资源和触发其它用途的SRS资源解耦。
需要说明的是，根据本申请的技术方案，可以实现将各种不同用途的非周期SRS资源的触发解耦。本申请的技术方案除了可以应用在触发用于定位的非周期SRS资源的场景下，也可以应用于触发其它用途的非周期SRS资源的场景下，本申请不作限制。本领域技术人员能够理解，将本申请各实施例中的用于定位的非周期SRS资源(集合)替换为所期望的用途(例如，用于码本传输、用于非码本传输、用于天线切换或用于波束管理等)的非周期SRS资源，则可以实现将“期望用途”的非周期SRS资源的触发与其它用途的非周期SRS资源的触发解耦。以下实施例中仅以将触发定位用途的非周期SRS资源和触发其它用途的非周期SRS资源进行解耦为例进行说明。
下面介绍本申请的技术方案。
参见图2，图2为本申请提供的触发非周期SRS资源的一种方法的示意图。
210、网络设备向终端设备发送DCI，DCI包括N个比特，N≥3且N为整数。
终端设备接收来自于网络设备的DCI。
其中，在一种实现方式中，所述N个比特中的M个比特用于触发一种或多种用途的非周期SRS资源集合，所述N个比特中的剩余(N-M)个比特用于指示是否触发用于定位的非周期SRS资源集合。
如上文所述，传统的DCI的SRS request字段包括2个比特，在本申请中，作为一个示例，在传统的SRS request字段中增加1个比特，增加的该1比特用于指示是否触发用于定位的非周期SRS资源集合。
也即，保持Rel-15中的非周期SRS资源集合的触发机制不变，在原有的基础上，在SRS request字段中增加1个比特，该1比特用于指示是否触发用于定位的非周期SRS资源集合。例如，增加的1比特设置为“1”，表示触发用于定位的非周期SRS资源集合；增加的1比特设置为“0”，表示不触发用于定位的非周期SRS资源集合。
需要说明的是，在这种实现方式中，SRS request字段原有的2比特所指示的SRS资源的用途不变。由此可以理解的是，若SRS request字段原有的2比特触发的SRS资源集合中不包括用于定位的非周期SRS资源集合，或者说，SRS request字段原有的2比特触发的非周期SRS资源的用途中不包括定位的用途，则增加的1比特应被设置为不触发用 于定位的非周期SRS资源集合。但是，若SRS request字段原有的2比特触发的非周期SRS资源集合包括用于定位的非周期SRS资源集合，或者说，SRS request字段原有的2比特触发的非周期SRS资源的用途中包括定位的用途，则增加的1比特可以被设置为不触发定位的用途，也可以被设置为触发定位的用途。
下面结合表2进行举例说明。在表2中，假设SRS request字段原本包括2个比特，新增加1比特用于指示是否触发用于定位的非周期SRS资源集合。由此，SRS request字段共包括3比特，假设按照从左向右的顺序，假设最高位(即，第1位)为增加的1比特。
表2

应理解，上述实施例中以1增加1个比特作为示例，也可以增加2比特或者更多比特来指示是否触发用于定位的非周期SRS资源集合。
此外，以上将N个比特的最高位设置为新增加的比特也是作为示例，容易想到其它的变形形式，例如，将新增加的1个比特设置在最低位或者其它位置也是可行的，本申请不作限制。
在另一种实现方式中，所述N个比特具有L个有效状态，所述L个有效状态中的部分有效状态仅对应一种用途的非周期SRS资源集合，所述一种用途的非周期SRS资源集合至少包括用于定位的非周期SRS资源集合。
换句话说，所述N个比特具有L个有效状态，所述L个有效状态中的部分有效状态 仅用于触发非周期SRS资源的一种用途。若设计所述部分有效状态中的某一种有效状态仅用于触发非周期SRS资源的定位的用途，则可以实现将触发定位的非周期SRS资源和触发其它用途的非周期SRS资源解耦。
在这种实现方式中，作为一个示例，在SRS request字段原来的2比特的基础上，增加若干个比特(例如，1个比特)，对SRS request字段的长度进行扩展，使得扩展后的SRS request字段共包括N个比特，所述N个比特可以表示L个有效状态，其中，所述L个有效状态中的一个有效状态仅用于触发定位用途的SRS资源。其中，L<2 N，N和L均为整数。
应理解，N个比特总共可以表示2 N个状态，可选地，作为一个示例，其余的(2 N-L)个状态可以作为保留状态，或者可以用于单独触发非周期SRS资源新增加的其它用途，本申请不作限定。
例如，扩展后的SRS request字段共包括3个比特，其中，3个比特可以表示8个状态，分别为000,001,010,011,100,101,110和111。与扩展前的SRS request字段相比，扩展后的SRS request字段所能表示的状态增加了4个。可以定义上述8个状态中的前4个状态与扩展前的SRS request字段的2比特所表示的含义相同，此外，再从增加的4个状态中选择一个状态专门用于触发定位用途的非周期SRS资源。
可选地，作为另一个示例，所述N个比特具有L个有效状态，所述L个有效状态中的每个有效状态唯一对应一种用途的非周期SRS资源，所述L个有效状态对应的非周期SRS资源集合包括用于定位的非周期SRS资源集合。
换句话说，所述N个比特具有L个有效状态，每个有效状态仅用于触发一种用途的非周期SRS资源集合，这样，也可以实现将触发用于定位的非周期SRS资源集合和触发其它用途的非周期SRS资源集合解耦。实际上，通过这种方式，可以实现将所有不同用途的非周期SRS资源的触发解耦。下面结合表3进行说明。
表3
SRS request字段表示的状态 触发的SRS资源
000 不触发任何用途的非周期SRS资源
001 触发用于码本的SRS资源
010 触发用于非码本的SRS资源
011 触发用于波束管理的SRS资源
100 触发用于天线切换的SRS资源
101 触发用于定位的SRS资源
110 保留
111 保留
应理解，在本申请中，有效状态是指被定义用于指示非周期SRS资源的用途的状态。例如，表3中，“110”和“111”可以认为不属于上述有效状态。
此外，需要注意的是，在后一种示例中(例如，表3的示例)，由于扩展后的SRS request字段的N个比特对应的L个有效状态的含义改变(即，与扩展前的SRS request字段的2个比特表示的含义不同)，因此，对于不同用途的非周期SRS资源的触发参数信息，需 要设置成与表3相对应。
即是说，每种用途的非周期SRS资源的触发参数信息关联所述N个比特的一个有效状态的取值，每种用途的非周期SRS资源会被所关联的有效状态的取值所触发。其中，不同用途的非周期SRS资源的触发参数信息各自所关联的有效状态的取值的设置与所述L个有效状态中的每个有效状态唯一对应的一种用途的非周期SRS资源集合的设置相同。
具体地，非周期SRS资源的触发参数信息具体可以为“aperiodicSRS-ResourceTrigger”字段。
例如，对于用于码本的SRS资源，aperiodicSRS-ResourceTrigger字段应设置为1，对应表3中的有效状“001”；
对于用于非码本的SRS资源，aperiodicSRS-ResourceTrigger字段应设置为2，对应表3中的有效状“010”；
对于用于波束管理的SRS资源，aperiodicSRS-ResourceTrigger字段应设置为3，对应表3中的有效状“011”；
对于用于天线切换的SRS资源，aperiodicSRS-ResourceTrigger字段应设置为4，对应表3中的有效状“100”；
对于用于定位的SRS资源，aperiodicSRS-ResourceTrigger字段应设置为5，对应表3中的有效状“101”。
220、终端设备根据DCI，发送用于定位的非周期的SRS资源集合中的非周期SRS资源。
终端设备根据DCI的SRS request字段所触发的非周期SRS资源的用途，发送与所述被触发的用途对应的非周期SRS资源。具体地，终端设备根据在接收DCI之前，从网络设备接收到的各种用途的非周期SRS资源的配置信息，发送与所述被触发的用途对应的非周期SRS资源。
例如，DCI的SRS request字段仅触发用于定位的非周期SRS资源集合，则终端设备向网络侧发送用于定位的非周期SRS资源集合中的非周期SRS资源，供网络侧测量，进而实现网络侧对UE的位置的估算。
下面再提供一种比特映射的方法，可以实现各种不同用途的非周期SRS资源的触发的解耦。
参见如下图3。图3示出了本申请提供的触发非周期SRS资源的另一种方法的示意图。
310、网络设备向终端设备发送MAC-CE信令，所述MAC-CE信令用于指示是否激活非周期SRS资源集合。
其中，所述MAC-CE信令包含R个比特，所述R个比特中的每个比特唯一对应一种用途的非周期SRS资源集合，所述R个比特中的每个比特用于指示所对应的非周期SRS资源集合是否被激活，R为正整数。
终端设备接收来自于网络设备的所述MAC-CE信令。根据所述MAC-CE信令，终端设备可以获知被激活非周期SRS资源集合。并且，根据所述R比特和非周期SRS资源集合之间的映射关系，终端设备可以获知非周期SRS资源的哪些用途被激活。
例如，如果为了实现对终端设备进行定位，网络侧可以将所述R个比特中与定位用途的非周期SRS资源集合对应的比特设置为“激活”，其它用途设置为“去激活”，从而，可 以将触发用于定位的非周期SRS资源与触发其它用途的非周期SRS资源解耦。
在该实施例中，只有被激活的非周期SRS资源集合，后续才会被DCI触发。假设步骤310中，所述MAC-CE信令激活了用于定位的非周期SRS资源集合，则网络设备再通过DCI触发被激活的所述用于定位的非周期SRS资源集合，如下面的步骤320。
320、网络设备向终端设备发送DCI，所述DCI用于触发终端设备发送用于定位的非周期SRS资源。
其中，所述用于定位的非周期SRS资源属于用于定位的SRS资源集合，所述用于定位的SRS资源集合属于被所述R个比特激活的非周期SRS资源集合。
终端设备接收来自于网络设备的所述DCI。
330、终端设备发送所述被触发的用于定位的非周期SRS资源集合中的SRS资源。
下面对图3提供的比特映射的方法进行举例说明。
例如，在MAC-CE信令中增加一个字段或比特映射(bitmap)，该bitmap用于激活RRC信令中配置的非周期SRS资源集合。具体地，bitmap中的每个比特唯一对应一个非周期SRS资源集合。若bitmap中的某个比特被设置为1，表示该比特对应的非周期SRS资源(集合)被激活，并且，只有被激活的非周期SRS资源(集合)才会被DCI触发。
假设，网络侧共配置了5个非周期SRS资源(集合)，其中，每个非周期SRS资源(集合)分别对应一种用途，分别为码本传输、非码本传输、波束管理、天线切换以及定位。作为一个示例，bitmap的长度可以设置为5个比特，所述5个比特按照从最高位到最低位(也即，从左到右)的顺序，每个比特对应的用途分别为码本传输、非码本传输、波束管理、天线切换以及定位。
作为一个示例，所述5个比特中的部分比特如果被设置为1(也可以设置其他数值或标识)，表示这些比特对应的用途的非周期SRS资源被激活。例如，bitmap被设置为“00001”，则从左到右的第5个比特(也即，最低位的比特)被设置为1，表示第5个比特对应的非周期SRS资源(即，用于定位用途的非周期SRS资源)被激活。则后续，网络侧只会通过DCI触发用于定位的非周期SRS资源的发送。
作为一个示例，DCI中的SRS request字段的长度可以根据bitmap所激活的非周期SRS资源的个数来配置。
例如，如果bitmap仅激活了一种用途的非周期SRS资源，则DCI通过1比特即可指示是否触发该用途的非周期SRS资源。例如，在上面的示例中，bitmap被设置为“00001”，则网络侧仅激活了用于定位的非周期SRS资源，则DCI可以通过1比特来指示是否触发用于定位的非周期SRS资源。作为一个示例，DCI被设置为1，表示触发用于定位的非周期SRS资源，DCI被设置为0，表示不触发用于定位的非周期SRS资源。
又例如，如果bitmap激活了两种或者两种以上用途的非周期SRS资源，则DCI可以通过2比特或者更多比特来指示是否触发被激活的非周期SRS资源。例如，DCI也可以设置为5个比特，其中，每个比特对应一种用途的非周期SRS资源。其中，如果网络侧触发被MAC-CE信令激活的某个非周期SRS资源，则DCI的5个比特中对应该用途的SRS资源的比特被设置为1，否则设置为0。此外，未被MAC-CE激活的非周期SRS资源对应的比特也设置为0。
例如，假设MAC-CE信令的bitmap被设置为“10001”，表示用于码本传输的SRS资 源和用于定位的SRS资源被激活。进一步地，网络侧向终端设备发送DCI，DCI被设置为“00001”，其中，按照从左向右的顺序，第1个比特设置为0，表示不触发用于码本传输的SRS资源，第5个比特设置为1，表示触发用于定位的SRS资源。另外，结合bitmap表示的含义，DCI的除了第1个比特和第5个比特之外的其余比特被设置为0，表示其它用途的SRS资源未被激活。
又例如，假设MAC-CE信令的bitmap被设置为“10001”，表示用于码本传输的SRS资源和用于定位的SRS资源被激活。进一步地，网络侧向终端设备发送DCI，DCI包括2个比特，其中，所述2个比特分别表示4种状态，分别为00,01,10和11。按照bitmap包含的比特对应的非周期SRS资源的用途，上述4种状态分别表示被激活的两种用途的SRS资源是否被触发的组合。例如，00表示用于码本传输的SRS资源和用于定位的SRS资源均不触发。01表示用于码本传输的SRS资源不被触发，而用于定位的SRS资源被触发。10表示用于码本传输的SRS资源被触发，而用于定位的SRS资源不被触发。11表示用于码本传输的SRS资源和用于定位的SRS资源均被触发。
可见，方法300与方法200的具体实现虽然不同，方法300也可以实现将不同用途的非周期SRS资源的触发解耦。
此外，本申请还提供一种另一种触发非周期SRS资源的方法，网络侧在RRC信令中增加字段(或者称为扩展字段)，对不同用途的非周期SRS资源进行分组，然后，根据需要触发的非周期SRS资源的用途，网络设备使用MAC-CE激活其中一组非周期SRS资源。最后，网络侧再用DCI触发该组中的非周期SRS资源，如图4所示。
参见图4，图4为本申请提供的触发非周期SRS资源的一个示例。例如，网络侧通过RRC信令，将不同用途的非周期SRS资源配置为P个组，其中，P>0且P为整数。每个组包括一种用途或多种用途的非周期SRS资源。或者说，每个组代表了不同用途的SRS资源的组合。在一个示例中，假设共有Q种用途的非周期SRS资源，则
Figure PCTCN2020084165-appb-000003
其中，Q为正整数。假设Q＝5，则
Figure PCTCN2020084165-appb-000004
在另一个示例中，网络侧可以仅配置P个组中的部分组，对于一些不常使用的非周期SRS资源的用途的组合不作配置，本申请不作限制。
可选地，作为一个示例，网络设备可以在高层参数SRS-config中增加一个字段“group”来实现。例如，网络侧在不同用途的SRS资源的配置参数中，将字段“group”设置为{1,2,3,…,N}中的一个或多个取值，表示激活“group”对应的组。进一步地，当MAC-CE激活所述字段“group”对应的组的中的任意一个时，DCI都会触发该组中的用于定位的非周期SRS资源集合。
例如，在图4的示例中，用于定位的非周期SRS资源既属于第五组，也属于第N组，其它包含用于定位用途的非周期SRS资源的组暂且忽略。在这种情况下，网络侧可以将高层参数SRS-config的字段“group”设置为{5，N}，当MAC-CE激活第5组或者第N组的情况下，DCI的SRS request字段都会触发用于定位的非周期SRS资源的发送。
作为一个示例，高层参数SRS-config的配置可以如下字段所示：

Figure PCTCN2020084165-appb-000006
参见图5，图5为本申请提供的触发非周期SRS资源的另一种方法的示意图。
510、网络设备向终端设备发送RRC信令，所述RRC信令包括扩展字段，所述扩展字段用于将不同用途的非周期SRS资源配置为P个组，每个组包含一种用途或多种用途的非周期SRS资源集合，其中，P>1且P为整数。
这里，多种用途包括两种用途以及两种以上的用途。
终端设备接收来自于网络设备的RRC信令，并根据RRC信令，获知不同用途的非周期SRS资源构成的所述P个组。
520、网络设备向终端设备发送MAC-CE信令，所述MAC-CE信令用于激活所述P个组中的一个组。
终端设备接收来自于网络设备的MAC-CE信令，并根据所述MAC-CE信令，获知被激活的组。
可以理解的是，所述P个组可以包括非周期SRS资源的不同用途的全部组合，因此，网络侧可以根据需要触发的不同用途的非周期SRS资源，从所述P个组中选择合适的组，通过MAC-CE信令触发。
以图4所示为例，如果网络侧仅需要触发一种用途的非周期SRS资源，以将该用途的非周期SRS资源的触发和其它用途的非周期SRS资源的触发解耦，网络设备仅需要激活所述P个组中仅包括所需用途的组即可。
例如，网络设备仅需要触发终端设备发送用于定位的非周期SRS资源，则网络设备通过MAC-CE激活第5组即可。又例如，网络设备仅需要触发用于波束管理的非周期SRS资源，则网络设备通过MAC-CE激活第3组即可。
又例如，若网络设备需要触发多个用途的非周期SRS资源，网络设备从所述P个组 中选择相应的组合，并通过MAC-CE激活即可。例如，网络设备需要触发用于码本传输和用于波束管理的两种用途的非周期SRS资源，则网络设备通过MAC-CE激活第6组即可。以此类推，不再赘述。
如果网络侧为了实现对终端设备进行定位，网络设备仅需要触发终端设备发送用于定位的非周期SRS资源，则网络设备通过MAC-CE激活第5组即可。从而，可以将触发用于定位的非周期SRS资源与触发其它用途的非周期SRS资源解耦。后续，网络设备再通过DCI触发终端设备发送被激活的非周期SRS资源集合中的非周期SRS资源，如下面的步骤530。
530、网络设备向终端设备发送DCI，DCI用于触发所述被激活的组中所包含的非周期SRS资源集合。
进一步地，方法500还可以包括步骤540。
540、终端设备向网络设备发送被触发的非周期SRS资源集合中的非周期SRS资源。
可以理解的是，在图5的方法中，网络设备通过配置不同用途的非周期SRS资源的P个组，使得不同的用途的非周期SRS资源的组合都有一个对应的组。如果网络侧只需要触发终端设备发送用于定位的非周期SRS资源，则可以通过MAC-CE来激活仅包含用于定位的非周期SRS资源的组即可。进一步地，网络侧再通过DCI触发该被激活的用于定位的非周期SRS资源的组中的非周期SRS资源，即可实现将触发用于定位的非周期SRS资源和触发其它用途的非周期SRS资源解耦。
另外，方法500还可以避免RRC的重配过程，只要通过MAC-CE快速切换不同组合的组，就能实现对不同用途的非周期SRS资源的灵活触发。
在本申请各实施例中，用于定位的用途是期望用途的一个示例。所述期望用途还可以是SRS资源的其它任意一个用途，并且解耦的实现方式与均是类似的。
另外，本申请各实施例中的非周期SRS资源集合中可以包括一个非周期SRS资源，也可以包括多个非周期SRS资源，不作限定。
以上各实施例中用于激活或触发非周期SRS资源集合的信令，例如，RRC信令、MAC-CE信令等仅是作为示例，也可以替换为本领域其它可行的消息或信令等，不作限定。
