Description

一种非周期SRS发送方法及相关设备
本申请要求于2020年01月10日提交中国专利局、申请号为202010029818.1、申请名称为“一种非周期SRS发送方法及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种非周期SRS发送方法及相关设备。
背景技术
探测参考信号(Sounding reference signal，SRS)是终端设备向基站等接入网设备发送的一种信号，用于使接入网设备根据SRS对上行信道质量进行估计，进而进行传输资源的调度。在长期演进(Long Term Evolution，LTE)系统中，SRS分为周期SRS(Periodic SRS)和非周期SRS(Aperiodic SRS)两种时域类型的SRS，在新无线电接入技术(New Radio Access Technology，NR)系统中，新增了半持续性SRS(semi-persistent SRS)，共三种时域类型的SRS。
SRS可以基于一定的SRS资源(SRS resource)发送，一个SRS资源通过无线资源控制(Radio Resource Control，RRC)配置的多个资源参数确定，这些资源参数可以是天线端口数、正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号数、频域位置、时隙位置等。多个时域类型相同的SRS资源可以组成SRS资源集(SRS resource set)。
其中，非周期SRS是通过接入网设备向终端设备发送的下行控制信息(Downlink Control Information，DCI)，由DCI触发终端设备发送的。对于非周期SRS资源集，通过RRC配置各自唯一对应的一个时隙偏移(slot offset)。在终端设备接收到DCI之后，可以获取DCI所触发的SRS资源集，其对应的RRC配置中的时隙偏移，进而确定发送非周期SRS的发送时隙。这种方式中，终端设备只能根据针对该SRS资源集的RRC配置中，固定的时隙偏移，确定非周期SRS的发送时隙，即在RRC配置后，任何终端设备针对SRS资源集发送非周期SRS的时隙偏移是固定的、一致的，这种确定SRS发送时隙的方式较为单一。

下面介绍本申请实施例提供的非周期SRS发送方法。本申请实施例提供的非周期SRS发送方法可以基于图1中的系统架构实现。参见图2，图2是本申请实施例提供的一种非周期SRS发送方法的流程示意图，如图所示，所述方法可以包括步骤S201-S202。
S201，第一终端设备接收第一控制指令。
其中，所述第一控制指令是用于触发所述第一终端设备发送非周期SRS的指令。一种实现方式中，所述第一控制指令可以是DCI，DCI中携带的参数以域的形式存在于DCI中，例如，DCI中可以包含SRS请求(SRS request)域、时域资源分配(time domain resource allocation，TDRA)域等。
所述第一控制指令中包含第一参数域，所述第一参数域中包含第一时隙偏移。一种实现方式中，第一控制指令通过显式指示的方式，指示第一终端设备发送非周期SRS的时隙偏移，那么，第一参数域可以是第一控制指令中专门用于动态灵活指示用户终端发送非周期SRS的时隙偏移的域，第一参数域中的第一时隙偏移是专门为非周期SRS发送指定的时隙偏移；另一种实现方式中，第一控制指令通过隐式指定的方式，指示第一终端设备发送非周期SRS的时隙偏移，那么第一参数域可以是TDRA域，TDRA域中的时隙偏移可以用于指示物理上行共享信道(physical uplink shared channel，PUSCH)或物理下行共享信道(physical downlink shared channel，PDSCH)的时隙偏移，这里将其用于指示发送非周期SRS的时隙偏移。
所述第一控制指令中还包含SRS资源集信息，SRS资源集信息是SRS资源集对应的指示信息，指示接入网设备触发第一终端设备针对哪一个或多个SRS资源集发送非周期SRS，即第一用户终端根据第一控制指令中的SRS资源集信息，可以确定触发的是哪个SRS资源集。一种实现方式中，SRS资源集信息可以是第一控制指令中SRS request域中的参数，即可以通过不同的SRS request取值，触发不同的SRS资源集。
具体的，在S201之前，可以通过RRC配置不同的SRS资源参数，以定义不同的SRS资源集，一种实现方式中，也可以通过RRC为各个SRS资源集配置固定的时隙偏移(即RRC配置时隙偏移)。接入网设备可以将SRS资源集对应的SRS资源参数配置给第一终端设备存储。接入网设备可以建立各个SRS资源集，与不同的aperiodic SRS-Resource Trigger 取值之间的对应关系，并将上述对应关系配置给第一终端设备，以使第一终端设备记录各个SRS资源集对应的aperiodic SRS-Resource Trigger取值；进而在步骤S201中，第一终端设备在获取第一控制指令中包含的SRS request取值(即SRS资源集信息)后，确定第一控制指令中SRS request取值对应的aperiodic SRS-Resource Trigger取值，进而根据记录的上述对应关系，确定到对应的SRS资源集，也可以进一步获取到对应的SRS资源参数，SRS资源参数后续用于发送非周期SRS。
举例来说，接入网设备配置了三个SRS资源集，这三个SRS资源集对应的高层配置参数aperiodic SRS-Resource Trigger的取值不同，这是三个SRS资源集对应的aperiodic SRS-Resource Trigger分别被配置为1、2和3。在DCI中SRS request域占用两个比特，通过这两个比特不同的取值代表不同的SRS资源集信息，一种示例性的实现方式中，取值为00的SRS request对应没有非周期SRS资源集被触发，取值为01的SRS request对应aperiodic SRS-Resource Trigger被配置为1的SRS资源集，取值为10的SRS request对应aperiodic SRS-Resource Trigger被配置为2的SRS资源集，取值为11的SRS request对应aperiodic SRS-Resource Trigger被配置为3的SRS资源集。若DCI中SRS request中的SRS request取值为11，第一终端设备可以确定接入网设备针对的是aperiodic SRS-Resource Trigger被配置为3的SRS资源集触发非周期SRS，进而可以获取对应的SRS资源参数，后续发送非周期SRS。而若第一控制指令中的SRS request取值为00，则第一终端设备可以确定无非周期SRS资源集被触发，可以根据其他信息判断是否满足发送周期性SRS或半持续性SRS的条件。
S202，所述第一终端设备根据所述第一时隙偏移，确定发送非周期SRS的时域位置，根据确定的所述时域位置发送非周期SRS。
在第一终端设备根据第一时隙偏移确定发送非周期SRS的时域位置的一种实现方式中，若第一终端设备在时隙n接收到了第一控制指令，第一时隙偏移为k，那么第一终端设备确定发送非周期SRS的时隙是n+k这一时隙，进而根据SRS资源集信息对应的SRS资源参数中的符号位置，确定出在n+k这一时隙中发送非周期SRS的符号(即发送非周期SRS的时域位置)。其中，符号位置为在RRC配置SRS资源时，配置的位于一个时隙(即发送非周期SRS的时隙)中的用于发送非周期SRS的符号的位置，一种实现方式中，该符号位置可以是用于发送非周期SRS的时隙中最后j个符号中的l个连续符号，示例性地，在NR中，j的取值可以是6，l的取值可以是1、2、或4，根据该符号位置可以确定到在n+k这一时隙中发送非周期SRS的符号。第一终端设备还获取第一控制指令中的SRS资源集信息对应的SRS资源集的SRS资源参数，如天线端口数、OFDM数、频域位置，根据这些SRS资源参数，在n+k时隙发送非周期SRS。
一种可选的实现方式中，在S201之前所述方法还可以包括，第一终端设备可以接收第一使能信息，第一使能信息可以是通过RRC配置的，用于指示第一终端设备根据第一参数域中的第一时隙偏移，确定发送非周期SRS的时域位置；然后第一终端设备在接收到第一控制指令后，根据第一使能信息，从第一参数域获取第一时隙偏移，根据第一时隙偏移，确定非周期SRS的时域位置，进而根据确定的时域位置发送非周期SRS。也就是说，若第一终端设备接收第一控制指令之前接收到了第一使能信息，则第一终端设备根据第一使能 信息，从第一参数域获取用于发送非周期SRS的时隙偏移，否则，第一终端设备将根据RRC配置确定发送非周期的SRS的时隙偏移。
另一种可选的方式中，在S202之后所述方法还可以包括：第一终端设备接收第二使能信息，第二使能信息用于指示第一终端设备根据RRC配置时隙偏移，确定发送非周期SRS的时域位置；第一终端设备接收第二控制指令，第二控制指令用于触发所述第一用户终端发送非周期SRS，第二控制指令中包含第四SRS资源集信息；第一终端设备根据所述第二使能信息，获取第四SRS资源集信息对应的RRC配置时隙偏移；第一终端设备根据第四SRS资源集信息对应的RRC配置时隙偏移，确定第六时域位置，并根据第六时域位置，发送非周期SRS。
上述两种可选的方式可以仅独立执行其中任意一种，也可以按先后顺序均执行，比如，第一终端设备在接收到第一使能信息后，第一终端设备根据第一参数域中的第一时隙偏移，确定发送非周期SRS的时域位置，在第一终端设备接收到第二使能信息后，将不再根据第一参数域中的第一时隙偏移确定发送非周期SRS的时域位置，而是根据RRC配置时隙偏移确定发送非周期SRS的时域位置；直到再次接收到第一使能信息后，第一终端设备根据第一参数域中的第一时隙偏移确定发送非周期SRS的时域位置。
也就是，第一使能信息和第二使能信息分别使第一终端设备按照不同的方式，确定发送非周期SRS的时隙偏移，可以将第二使能信息看作是第一使能信息对应的去使能信息。第一使能信息和第二使能信息均可以是通过RRC配置的同一类型的使能信息，二者包含相同的字段类型；这些字段类型中包含一个指示第一终端设备是按照第一参数域中的第一时隙偏移还是按照RRC配置时隙偏移，确定发送非周期SRS的时域位置的使能字段类型，第一终端设备接收到使能信息后，可以通过该使能字段类型的取值的不同，识别接收到的使能信息是指示按照第一参数域中的第一时隙偏移确定发送非周期SRS的时域位置的第一使能信息，还是指示按照RRC配置时隙偏移确定发送非周期SRS的时域位置的第二使能信息，进而确定发送非周期SRS的时域位置，并发送非周期SRS。
在第一终端设备根据第一时隙偏移确定发送非周期SRS的时域位置的另一种实现方式中，第一使能信息可以具体用于指示第一终端设备根据第一参数域中的第一时隙偏移，以及RRC配置时隙偏移，确定发送非周期SRS的时域位置。具体的，若第一终端设备在S202之前接收到的第一使能信息，第一终端设备在时域s接收到了第一控制指令，第一时隙偏移为r，第一控制指令中SRS资源集信息对应的SRS资源集的RRC配置时隙偏移为t，那么，第一终端设备将时隙s+r+t确定为发送非周期SRS的时隙，进而根据SRS资源集信息对应的SRS资源参数中的符号位置，确定出在s+r+t这一时隙中发送非周期SRS的符号(即发送非周期SRS的时域位置)。
其中，在第一控制指令中包含的SRS资源集信息可以是包含一个SRS资源集对应的SRS资源集信息，也可以是包含多个SRS资源集对应的SRS资源集信息。例如，若aperiodic SRS-Resource Trigger被配置为1的SRS资源集有一个，当第一控制指令中SRS request取值为01时，即第一控制指令中仅包含一个SRS资源集对应的SRS资源集信息；若aperiodic SRS-Resource Trigger被配置为2的SRS资源集有多个，当第一控制指令中SRS request取值为10时，即第一控制指令中仅包含多个SRS资源集对应的SRS资源集信息。
第一种可选的实现方式中，第一控制指令中的SRS资源集信息仅包含一个第一SRS资源集对应的第一SRS资源集信息，那么，第一终端设备根据第一时隙偏移，确定第一时隙位置，并根据第一时域位置，基于第一SRS资源集对应的SRS资源参数，发送非周期SRS。这里，第一控制指令可以是接入网设备在第一终端设备不期待或不支持被同时触发多个SRS资源集的情况下，发送给第一终端设备的；也可以是在第一终端设备期待或支持被同时出发多个SRS资源集的情况下，接入网设备仅需要第一终端设备针对一个第一SRS资源集发送非周期SRS时，发送给第一终端设备的。
第二种可选的实现方式中，第一控制指令中的SRS资源集信息包含多个第二SRS资源集各自对应的第二SRS资源集信息，那么，第一终端设备可以忽略第一控制指令指示的第一时隙偏移，按照各个第二SRS资源集对应的RRC配置时隙偏移发送非周期SRS。因此，针对上述各个第二SRS资源集，所述方法还包括：第一终端设备根据各个第二SRS资源集信息，获取各个第二SRS资源集对应的RRC配置时隙偏移，根据各个第二SRS资源集对应的RRC配置时隙偏移，确定各个第二SRS资源集对应的第二时域位置，进而根据各个第二SRS资源集对应的SRS资源参数，在各自对应的第二时域位置，发送非周期SRS。
第三种可选的实现方式中，第一控制指令中的SRS资源集信息中包含多个第三SRS资源集各自对应的第三SRS资源集信息，第一终端设备可以从第三SRS资源集中选取一个指定的第三SRS资源集，进而根据第一时隙偏移，确定第三时域位置，并根据所述指定的第三SRS资源集对应的SRS资源参数，针对该指定的第三SRS资源集，发送非周期SRS。其中，指定的第三SRS资源集的确定方式可以有多种，例如，将这多个第三SRS资源集中资源集标识最小的第三SRS资源集，作为指定的第三SRS资源集，又如，将这多个第三SRS资源集中资源集标识最大的第三SRS资源集，作为指定的第三SRS资源集。可选的，也可以确定多个指定第三SRS资源集，根据第一时隙偏移发送非周期SRS。具体确定指定的第三SRS资源集的方式可以有多种，这里不做限定，但无论哪种具体的确定方式，在接入网设备内的各个终端设备都应该按照约定的同一种确定方式确定该指定的第三SRS资源集。
结合上述第三种可选的实现方式，进一步可选的，在第一终端设备除了针对上述指定的第三SRS资源集发送非周期SRS以外，不再针对其他的第三SRS资源集发送非周期SRS。
结合上述第三种可选的实现方式，进一步可选的，在第一终端设备除了针对上述指定的第三SRS资源集发送非周期SRS以外，还针对其他的第三SRS资源集发送非周期SRS。具体的，所述方法还可以包括：第一终端设备可以根据第三SRS资源集信息，获取除所述指定的第三SRS资源集以外，剩余的第三SRS资源集各自对应的RRC配置时隙偏移，进而根据各个所述剩余的第三SRS资源集对应的RRC配置时隙偏移，确定各个所述剩余的第三SRS资源集对应的第四时域位置，第一终端设备针对各个剩余的第三SRS资源集，根据各自对应的第四时域位置，发送非周期SRS。
第四种可选的实现方式中，第一控制指令中的SRS资源集信息中包含多个第五SRS资源集各自对应的第五SRS资源集信息，第一终端设备可以忽略第一控制指令，不针对任意第五SRS资源集发送非周期SRS。
第五种可选的实现方式中，第一控制指令可以是接入网设备在第一终端设备不期待或 不支持被同时触发多个SRS资源集的情况下，发送给第一终端设备的，并且第一控制指令中的SRS资源集信息中包含多个第六SRS资源集各自对应的第六SRS资源集信息，那么第一终端设备确定此事件是错误事件，不发送非周期SRS。
需要说明的是上述第二种可选的实现方式、第三种可选的实现方式(包括第三种可选的实现方式的进一步的可选实现)、第四种可选的实现方式和第五种可选的实现方式，都是针对第一控制指令中包含多个SRS资源集信息的情况，第一终端设备可以在预先设置好执行模式的情况下(即预先设置好的执行模式是上述第二种可选的实现方式、第三种可选的实现方式、第四种可选的实现方式或第五种可选的实现方式中的任一种)，按照设置好的执行模式执行。另一种可能的实现方式中，第一控制指令中还可以包含第三使能信息，第三使能信息用于指示第一终端设备在第一控制指令包含多个SRS资源集信息时，按照上述何种方式执行，进而第一终端设备可以按照第三使能信息指示的方式执行。可选的，第三使能信息可以与第一使能信息或第二使能信息为同一使能信息。
可选的，若预先并未通过RRC配置SRS资源集的时隙偏移，这里可以通过第一控制指令隐式指示第一终端设备发送非周期SRS的时隙偏移，即第一参数域为TDRA域，这时，若第一控制指令中的SRS资源集信息仅包含一个SRS资源对应的SRS资源集信息，那么按照第一控制指令隐式指示的TDRA域中的时隙偏移发送非周期SRS。若第一控制指令中的SRS资源集信息包含多个SRS资源各自对应的SRS资源集信息，即触发了多个SRS资源集，那么一种实现方式中，第一终端设备可以仅从中确定一个指定的SRS资源集(如低资源集标识对应的SRS资源集)，按照第一控制指令隐式指示的TDRA域中的时隙偏移，针对该在指定的SRS资源集发送非周期SRS，不针对其他的SRS资源集发送非周期SRS；或者另一种实现方式中，若第一控制指令中的SRS资源集信息包含多个SRS资源各自对应的SRS资源集信息，则第一终端设备可以忽略第一控制信令，不发送非周期SRS；或者另一种实现方式中，若第一控制指令是接入网设备在第一终端设备不期待或不支持被同时触发多个SRS资源集的情况下，发送给第一终端设备的，并且第一控制指令中的SRS资源集信息包含多个SRS资源各自对应的SRS资源集信息，则第一终端设备确定此事件是错误事件，不发送非周期SRS。
本申请实施例中，第一终端设备接收第一控制指令，其中，第一控制指令用于触发第一终端设备发送非周期SRS，第一控制指令中包含第一参数域和SRS资源集信息，第一参数域中包含第一时隙偏移；第一终端设备根据第一时隙偏移，确定发送非周期SRS的时域位置，并根据确定的时域位置发送非周期SRS。通过第一控制指令中携带的第一时隙偏移，动态地指示第一终端设备发送非周期SRS的时隙偏移，进而根据动态指示的时隙偏移确定发送非周期SRS的时域位置，提高了非周期SRS的发送时隙确定方式的灵活性和多样性。
参见图3，图3是本申请实施例提供的另一种非周期SRS发送方法的流程示意图，如图所示，所述方法包括步骤S301～S305。
S301，第一终端设备接收第一控制指令。
所述第一控制指令用于触发所述第一终端设备发送非周期SRS，所述第一控制指令中包含第一参数域和SRS资源集信息，所述第一参数域中包含第一时隙偏移。这里，第一控 制指令可以是通过隐式指示的方式，指示第一终端发送非周期SRS的时隙偏移，那么第一参数域可以是TDRA域。
第一控制指令中还包括获取方式指示域，所述获取方式指示域中包含第一获取方式信息或第二获取方式信息中的一种；所述第一获取方式信息用于指示所述第一终端设备从所述第一参数域中获取时隙偏移；所述第二获取方式信息用于指示所述第一终端设备从RRC配置参数中获取时隙偏移。
S302，第一终端设备获取第一控制指令中获取方式指示域中的参数。
在获取方式指示域中的参数是第一获取方式信息或第二获取方式信息中的一种，若是第一获取方式信息，则执行S303，若是第二获取方式信息，则执行S304。可选的，获取方式指示域可以有一个比特，通过这一个比特的不同取值代表不同的参数，例如预先配置取值为0对应第一获取方式信息，取值为1对应第二获取方式信息，若第一控制指令中获取方式指示域中的取值为0，则执行S303，若取值为1，则执行S304。
S303，第一终端设备根据所述第一时隙偏移，确定发送非周期SRS的时域位置，根据确定的所述时域位置发送非周期SRS。
其中，第一控制指令中包含的SRS资源集信息可以是一个SRS资源集对应的SRS资源集信息，也可以包含多个SRS资源集对应的SRS资源集信息。具体的实现方式可以参阅图2对应的实施例中步骤S202的具体的实现方式，此处不在赘述。
S304，第一终端设备获取所述SRS资源集信息对应的RRC配置时隙偏移。
在S301之前，可以通过RRC配置不同的SRS资源参数，以定义不同的SRS资源集，一种实现方式中，也可以通过RRC为各个SRS资源集配置固定的时隙偏移(即RRC配置时隙偏移)。接入网设备可以将SRS资源集对应的SRS资源参数配置给第一终端设备存储。接入网设备可以建立各个SRS资源集与不同的aperiodic SRS-Resource Trigger取值之间的建立对应关系，并将上述对应关系配置给第一终端设备，以使第一终端设备记录各个SRS资源集对应的aperiodic SRS-Resource Trigger取值；进而在步骤S304中，第一终端设备在获取第一控制指令中包含的SRS request取值(即SRS资源集信息)后，确定第一控制指令中SRS request取值对应的aperiodic SRS-Resource Trigger取值，进而根据记录的上述对应关系，确定到第一控制指令中包含的SRS资源集信息对应的SRS资源集，也可以进一步获取到对应的SRS资源参数，SRS资源参数后续用于发送非周期SRS。
S305，第一终端设备根据所述SRS资源集信息对应的RRC配置时隙偏移，确定第五时域位置，并根据所述第五时域位置，发送非周期SRS。
这里，RRC配置时隙偏移是SRS资源集信息对应的SRS资源集被配置的固定的时隙偏移，第五时域位置是根据该时隙偏移确定的第一终端设备发送非周期SRS的时域位置。具体的，若第一终端设备在时隙m接收到了第一控制指令，SRS资源集信息对应的RRC配置时隙偏移为h，那么第一终端设备确定在m+h的时隙发送非周期SRS，时隙m+h即为发送SRS的时隙，进而根据SRS资源集信息对应的SRS资源参数中的符号位置，确定出在m+h这一时隙中发送非周期SRS的符号(即发送非周期SRS的第五时域位置)。其中，符号位置为在RRC配置SRS资源时，配置的位于一个时隙(即发送非周期SRS的时隙)中的用于发送非周期SRS的符号(即发送非周期SRS的时域位置)，一种实现方式中，该 符号位置可以是用于发送非周期SRS的时隙中最后j个符号中的l个连续符号，示例性地，在NR中，j的取值可以为6，l的取值可以是1、2、或4，根据该符号位置可以确定到在m+h这一时隙中发送非周期SRS的符号。第一终端设备还获取第一控制指令中的SRS资源集信息对应的SRS资源集的其他SRS资源参数，如天线端口数、OFDM数、频域位置，根据这些SRS资源参数，在m+h时隙中对应的符号发送非周期SRS。
第一控制指令中包含的SRS资源集信息可以是一个SRS资源集对应的SRS资源集信息，也可以包含多个SRS资源集对应的SRS资源集信息。
第一种可选的实现方式中，若第一控制指令中的SRS资源集信息仅包含一个SRS资源集对应的SRS资源集信息，那么，第一终端设备按照获取方式指示域中对应的第二获取方式信息(即指示所述第一终端设备从RRC配置参数中获取时隙偏移)，根据该SRS资源集对应的RRC配置时隙偏移，确定第五时域位置，并在第五时域位置，发送非周期SRS。这里，第一控制指令可以是接入网设备在第一终端设备不期待或不支持被同时触发多个SRS资源集的情况下，发送给第一终端设备的；也可以是在第一终端设备期待或支持被同时出发多个SRS资源集的情况下，接入网设备仅需要第一终端设备针对一个SRS资源集发送非周期SRS时，发送给第一终端设备的。
第二种可选的方式中，第一控制指令中的SRS资源集信息包含多个SRS资源集各自对应的SRS资源集信息，那么，第一终端设备可以忽略第一控制指令指示的时隙偏移，直接按照各个SRS资源集信息对应的RRC配置时隙偏移发送非周期SRS。因此，针对上述各个SRS资源集，第一终端设备根据各个SRS资源集信息，获取各个SRS资源集对应的RRC配置中的时隙偏移，根据各个SRS资源集对应的RRC配置中的时隙偏移，确定各个SRS资源集对应的第五时域位置，进而根据各个SRS资源集对应的SRS资源参数，在各自对应的第五时域位置，发送非周期SRS。
第三种可选的实现方式中，在第一控制指令中的SRS资源集信息中包含多个SRS资源集各自对应的SRS资源集信息时，第一终端设备按照获取方式指示域中对应的第二获取方式信息(即指示所述第一终端设备从RRC配置参数中获取时隙偏移)，可以从多个SRS资源集中选取一个指定的SRS资源集，并根据获取该指定的SRS资源集对应的RRC配置时隙偏移，确定针对该指定的非周期SRS资源集发送非周期SRS的第五时域位置，并根据该指定的SRS资源集对应的SRS资源参数，在对应的第五时域位置，发送非周期SRS。其中，指定的SRS资源集的确定方式可以有多种，例如，将第一控制指令中这多个SRS资源集中资源集标识最小的SRS资源集，作为指定的SRS资源集，又如，将第一控制指令中这多个SRS资源集中资源集标识最大的SRS资源集，作为指定的SRS资源集。可选的，也可以确定多个指定SRS资源集，按照获取方式指示域中对应的第二获取方式信息，确定发送非周期SRS的时隙偏移。具体确定指定的SRS资源集的方式可以有多种，这里不做限定，但无论哪种具体的确定方式，在接入网设备内的各个终端设备都应该按照约定的同一种确定方式确定该指定的SRS资源集。
结合上述第三种可选的实现方式，进一步可选的，在第一终端设备除了针对上述指定的SRS资源集发送非周期SRS以外，不再针对其他的SRS资源集发送非周期SRS。
结合上述第三种可选的实现方式，进一步可选的，在第一终端设备除了针对上述指定 的SRS资源集发送非周期SRS以外，还针对其他的SRS资源集发送非周期SRS。具体的，第一终端设备可以获取其他的SRS资源集各自对应的RRC配置时隙偏移，进而根据各个其他的SRS资源集对应的RRC配置时隙偏移，确定各个其他SRS资源集对应的发送时隙，第一终端设备针对各个其他的SRS资源集，根据各自对应的发送时隙发送非周期SRS。
第四种可选的实现方式中，第一控制指令中的SRS资源集信息中包含多个SRS资源集各自对应的SRS资源集信息，第一终端设备可以忽略第一控制指令，不针对任意SRS资源集发送非周期SRS。
第五种可选的实现方式中，第一控制指令可以是接入网设备在第一终端设备不期待或不支持被同时触发多个SRS资源集的情况下，发送给第一终端设备的，并且第一控制指令中的SRS资源集信息中包含多个SRS资源集各自对应的SRS资源集信息，那么第一终端设备确定此事件是错误事件，不发送非周期SRS。
需要说明的是上述第二种可选的实现方式、第三种可选的实现方式(包括第三种可选的实现方式的进一步的可选实现)、第四种可选的实现方式以及第五种可选的实现方式，都是针对第一控制指令中包含多个SRS资源集信息的情况，第一终端设备可以在预先设置好执行模式的情况下(即预先设置好的执行模式是上述第二种可选的实现方式、第三种可选的实现方式、第四种可选的实现方式或第五种可选的实现方式中的任意一种)，按照设置好的执行模式执行。另一种可能的实现方式中，第一控制指令中还可以包含第四使能信息，第四使能信息用于指示第一终端设备在第一控制指令包含多个SRS资源集信息时，按照上述何种方式执行，进而第一终端设备可以按照第四使能信息指示的方式执行。可选的，第四使能信息可以与第一使能信息、第二使能信息或第三使能信息为同一使能信息。
本申请实施例中，第一终端设备接收第一控制指令，其中，第一控制指令用于触发第一终端设备发送非周期SRS，第一控制指令中包含获取方式指示域，在获取方式指示域中为第一获取方式信息的情况下，按照第一控制指令中隐式指示的时隙偏移发送非周期SRS，在获取方式指示域中为第二获取方式信息的情况下，按照RRC配置的时隙偏移发送非周期SRS，实现了动态指示发送非周期SRS的时隙偏移，提高了非周期SRS的发送时隙确定方式的灵活性和多样性。
