在一种实现方式中，终端设备至少根据DCI的时域资源位置，确定GNSS测量间隙的位置的具体实施方式可以为：终端设备根据DCI的时域资源位置和时间偏移量，确定GNSS测量间隙的位置；其中，该时间偏移量为GNSS测量间隙与该DCI的时域资源之间的时长。
可选的，该时间偏移量可以为GNSS测量间隙的起始位置与该DCI的时域资源的结束位置之间的时长，此时，终端设备可以根据DCI的时域资源的结束位置和该时间偏移量，确定GNSS测量间隙的起始位置。示例性的，GNSS测量间隙的起始位置为DCI的时域资源的结束位置和该时间偏移量之和。示例性的，以图3所示的GNSS测量间隙的时序图为例，DCI的时域资源的结束位置在子帧n1，且时间偏移量为k个子帧，那么GNSS测量间隙的起始位置在子帧n1+k。

需要说明的是，上述示例中时间偏移量的单位、GNSS测量间隙的时长的单位为子帧用于举例，在其他实现方式中，时间偏移量的单位、GNSS测量间隙的时长的单位还可以是毫秒、秒、时隙、符号(如正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号)、帧或其他单位，本申请实施例对此不做限定。
在一种实现方式中，终端设备至少根据前述数据的时域资源位置，确定GNSS测量间隙的位置的具体实施方式可以为：终端设备根据该数据的时域资源位置和时间偏移量，确定GNSS测量间隙的位置；其中，该时间偏移量为GNSS测量间隙与该数据的时域资源之间的时长。
可选的，该时间偏移量可以为GNSS测量间隙的起始位置与该数据的时域资源的结束位置之间的时长，此时，终端设备可以根据该数据的时域资源的结束位置和该时间偏移量，确定GNSS测量间隙的起始位置。示例性的，GNSS测量间隙的起始位置为该数据的时域资源的结束位置和该时间偏移量之和。示例性的，以图4所示的GNSS测量间隙的时序图为例，DCI所调度的数据的时域资源的结束位置在子帧n2，且时间偏移量为k个子帧，那么GNSS测量间隙的起始位置在子帧n2+k。
可选的，该时间偏移量还可以为GNSS测量间隙的结束位置与该数据的时域资源的结束位置之间的时长，此时，终端设备可以根据该数据的时域资源的结束位置、该时间偏移量以及GNSS测量间隙的时长，确定GNSS测量间隙的起始位置和结束位置。示例性的，GNSS测量间隙的结束位置为该数据的时域资源的结束位置与该时间偏移量之和，GNSS测量间隙的起始位置为GNSS测量间隙的结束位置与GNSS测量间隙的时长之差。示例性的，若DCI所调度的数据的时域资源的结束位置在子帧n2，且时间偏移量为(k+m)个子帧，GNSS测量间隙的时长为m个子帧，那么GNSS测量间隙的结束位置在子帧n2+(k+m)，GNSS测量间隙的开始位置在子帧n2+(k+m)-m＝n2+k。
在一种实现方式中，网络设备还可以发送第一指示信息，相应的，终端设备接收该第一指示信息，该第一指示信息用于指示前述时间偏移量。网络设备可以在发送DCI之前，发送第一指示信息，相应的，终端设备在接收DCI之前接收该第一指示信息。该第一指示信息可以携带于高层信令、系统信息或前述DCI(即前述DCI还用于指示时间偏移量)中。示例性的，高层信令可以为RRC(Radio Resource Control，无线资源控制)信令。在另一种实现方式中，时间偏移量还可以通过协议预定义。

可选的，DCI可以显式指示或隐式指示是否启用GNSS测量间隙。
显式指示是指DCI中包括用于指示是否启用GNSS测量间隙的指示域。示例性的，该DCI包括指示信息a(即该指示域)，该指示信息a用于指示是否启用GNSS测量间隙。以DCI中设定1比特来承载该指示信息a为例，指示信息a对应的比特位取值为0的情况下，指示信息a用于指示不启用GNSS测量间隙，指示信息a对应的比特位取值为1的情况下，指示信息a用于指示启用GNSS测量间隙。其中，该DCI还可以用于调度数据，或者，该DCI还可以用于触发随机接入过程。
隐式指示可以是指DCI的类型与是否启用GNSS测量间隙具有对应关系(如称为对应关系1)，终端设备接收到DCI并译码后可以根据该对应关系1确定是否启用GNSS测量间隙。DCI的类型可以包括但不限于：用于触发随机接入过程的DCI、用于调度数据的DCI。示例性的，以对应关系1包括如下内容为例：用于触发随机接入过程的DCI与启用GNSS测量间隙具有对应关系，用于调度数据的DCI与启用GNSS测量间隙具有对应关系。若终端设备接收到用于触发随机接入过程的DCI，那么该DCI隐式指示启用GNSS测量间隙，换言之，终端设备接收到用于触发随机接入过程的DCI(即PDCCH Order)的情况下，默认启用GNSS测量间隙。若终端设备接收到用于调度数据的DCI，那么该DCI隐式指示启用GNSS测量间隙；若终端设备接收到的DCI不用于触发随机接入过程，也不用于调度数据，那么该DCI可以隐式指示不启用GNSS测量间隙。
或者，隐式指示还可以是指DCI中包括与是否启用GNSS测量间隙具有对应关系(如称为对应关系2)的信息(如称为信息b)，终端设备可以通过该信息b以及该对应关系2确定是否启用GNSS测量间隙。其中，该信息b可以由DCI中原有的指示域承载，即无需在DCI中通过扩展新的指示域以指示是否启用GNSS测量间隙。示例性的，假设信息b通过DCI中的格式指示字段承载，且该格式指示字段占用1比特，对应关系2包括如下内容：格式指示字段对应的比特位取值为1与启用GNSS测量间隙具有对应关系，格式指示字段对应的比特位取值为0与不启用GNSS测量间隙具有对应关系。若终端设备接收到的DCI中的格式指示字段对应的比特位取值为1，那么该DCI隐式指示启用GNSS测量间隙；若终端设备接收到的DCI中的格式指示字段对应的比特位取值为0，那么该DCI隐式指示不启用GNSS测量间隙。其中，该DCI还可以用于调度数据，或者，该DCI还可以用于触发随机接入过程。
可选的，是否在GNSS测量间隙内进行GNSS测量除了通过DCI指示是否启用GNSS测量间隙触发之外，还可以通过历史GNSS测量结果是否失效来确定。历史GNSS测量结果是最近一次GNSS测量所得到的结果。在一种实现方式中，若历史GNSS测量结果失效，终端设备可以在GNSS测量间隙内进行GNSS测量。其中，历史GNSS测量结果失效，终端设备可以确定需要启用GNSS测量间隙，进一步的，终端设备可以在GNSS测量间隙内进行GNSS测量。可以理解的是，历史GNSS测量结果有效，终端设备可以确定不需要启用GNSS测量间隙，相应的，也就不进行GNSS测量。
在一种实现方式中，前述历史GNSS测量结果失效是指：历史GNSS测量结果对应的定时器超时。其中，历史GNSS测量结果对应的定时器是在得到该历史GNSS测量结果的情况下启动的。该定时器的定时时长为历史GNSS测量结果的有效时长，待定时器超时(或计时结束)时，该历史GNSS测量结果失效。定时器未超时(或计时未结束)，那么历史GNSS测量结果有效。需要说明的是，每进行一次GNSS测量生成相应的GNSS测量结果的情况下，均可以启动对应的定时器。
示例性的，以历史GNSS测量结果的有效时长为3s为例，终端设备在完成GNSS测量并得到GNSS测量结果的情况下，可以启动该GNSS测量结果对应的定时器，该定时器从3s开始倒计时，在该定时器显示为0s的情况下，该定时器超时，此时，该GNSS测量结果失效。该定时器还可以为正计时器，示例性的，以历史GNSS测量结果的有效时长为3s为例，终端设备在完成GNSS测量并得到GNSS测量结果的情况下，可以启动该GNSS测量结果对应的定时器，该定时器从0s开始计时，在该定时器显示为3s或大于3s的情况下，该定时器超时，此时，该GNSS测量结果失效。
在另一种实现方式中，前述历史GNSS测量结果失效是指：历史GNSS测量结果的缓存时长大于该历史GNSS测量结果的有效时长。历史GNSS测量结果的缓存时长小于或等于该有效时长的情况下，该历史GNSS测量结果有效。
需要说明的是，历史GNSS测量结果失效可以单独触发在GNSS测量间隙内进行GNSS测量，此时，DCI可以不用于指示是否启用GNSS测量间隙。换言之，是否在GNSS测量间隙内进行GNSS测量可以仅参考历史GNSS测量结果是否失效，而不参考DCI的指示内容或者DCI不具有指示是否启用GNSS测量间隙的功能。示例性的，终端设备在GNSS测量间隙内执行GNSS测量后，就启动定时器，该定时器未超时(即历史GNSS测量结果有效)期间，终端设备不需要启动GNSS测量间隙执行GNSS测量。定时器超时(即历史GNSS测量结果失效)，终端设备就可以启用GNSS测量间隙并在该GNSS测量间隙内执行GNSS测量。
或者，终端设备可以结合DCI的指示内容以及历史GNSS测量结果是否失效，以确定是否在GNSS测量间隙内进行GNSS测量。这种情况下，是否在GNSS测量间隙内进行GNSS测量需要参考历史GNSS测量结果是否失效以及DCI的指示内容。示例性的，DCI用于指示(隐式指示或显式指示)启用GNSS测量间隙，且历史GNSS测量结果失效的情况下，终端设备可以在GNSS测量间隙内进行GNSS测量；DCI用于指示(隐式指示或显式指示)启用GNSS测量间隙，且历史GNSS测量结果有效的情况下，终端设备可以不进行GNSS测量。以终端设备接收到PDCCH Order的情况下默认启用GNSS测量间隙(即DCI用于隐式指示启用GNSS测量间隙)为例，是否执行GNSS测量的场景示意图如图5所示，其中，PDCCH Order还用于触发随机接入过程。参见图5，终端设备在GNSS测量间隙1内执行GNSS测量后，就启动定时器1，执行GNSS测量得到GNSS测量结果1，定时器1的定时时长为GNSS测量结果1的有效时长；终端设备接收到PDCCH Order-1时定时器1未超时(即GNSS测量结果1有效)，此时，该终端设备确定不需要启动GNSS测量间隙执行GNSS测量，在接收到PDCCH Order-1后发送PRACH。终端设备接收到PDCCH Order-2时定时器1已超时(即GNSS测量结果1失效)，此时，该终端设备确定需要启动GNSS测量间隙 2执行GNSS测量，终端设备在GNSS测量间隙2内执行GNSS测量后，就启动新的定时器2，并且执行GNSS测量后发送PRACH。其中，定时器1和定时器2的定时时长相同。
或者，图5对应的示例中，PDCCH Order中可以设定1比特来承载前述指示信息a(图5未示出)，前述指示信息a用于显式指示是否启用GNSS测量间隙，指示信息a对应的比特位取值为0的情况下，指示信息a用于指示不启用GNSS测量间隙，指示信息a对应的比特位取值为1的情况下，指示信息a用于指示启用GNSS测量间隙。以PDCCH Order-1和PDCCH Order-2中的指示信息a对应的比特位取值均为1为例，如图5所示，终端设备接收到PDCCH Order-1时定时器1未超时，该终端设备确定不需要启动GNSS测量间隙执行GNSS测量，在接收到PDCCH Order-1后发送PRACH。终端设备接收到PDCCH Order-2时定时器1已超时，该终端设备确定需要启动GNSS测量间隙2执行GNSS测量，终端设备在GNSS测量间隙2内执行GNSS测量后，就启动新的定时器2，并且执行GNSS测量后发送PRACH。
通过这种方式，有利于避免频繁地进行GNSS测量，从而有利于节省资源，延长终端设备的电池寿命。对于物联网终端设备而言，对电池寿命要求比较高，频繁的执行GNSS测量，会严重缩短设备的电池寿命。
在一种实现方式中，在通过上述方式确定不启用GNSS测量间隙或者确定不进行GNSS测量的情况下，终端设备可以执行如下步骤：若DCI用于触发随机接入过程，终端设备可以发送物理随机接入信道(Physical Random Access Channel，PRACH)；若DCI用于调度数据，终端设备可以根据该DCI中的指示确定数据传输的时频资源并通过该时频资源传输该数据。其中，终端设备发送PRACH是指：在PRACH上发送随机接入请求。终端设备传输该数据是指：根据DCI中的调度信息进行上行数据发送或下行数据接收。例如，终端设备在物理上行共享信道(Physical Uplink Shared Channel，PUSCH)上发送上行数据，或，终端设备在物理下行共享信道(Physical Downlink Shared Channel，PDSCH)上接收下行数据。
在一种实现方式中，网络设备还可以发送第三指示信息，相应的，终端设备接收该第三指示信息，该第三指示信息用于指示前述定时器的定时时长。网络设备可以在发送DCI之前，发送第三指示信息，相应的，终端设备在接收DCI之前接收该第三指示信息。该第三指示信息可以携带于高层信令、系统信息或前述DCI(即前述DCI还用于指示定时器的定时时长)中。可选的，该第三指示信息可以占用1个比特或更多比特。以第三指示信息占用1比特为例，该1比特取值为1可以表示启用GNSS测量间隙，该1比特取值为0可以表示不启用GNSS测量间隙。在另一种实现方式中，定时器的定时时长还可以通过协议预定义。可选的，历史GNSS测量结果的有效时长可以由网络设备指示，或者可以由协议预定义，本申请实施例对此不做限定。
在一种实现方式中，网络设备可通过如下方式确定前述定时器的定时时长：终端设备上报定时参考指示信息，该定时参考指示信息用于指示GNSS测量结果的参考有效时长。相应的，网络设备接收该定时参考指示信息；并根据该参考有效时长，确定前述定时器的定时时长。可选的，该参考有效时长可以根据该终端设备的能力和/或终端设备的移动性信息确定。示例性的，若终端设备的电池容量较大，则参考有效时间可以较短。若终端设备的位置在较长的时间内能保持不变，那么参考有效时间可以较长。终端设备的位置在较短 的时间内保持不变，那么参考有效时间可以较短。可选的，网络设备可以将终端设备上报的参考有效时长确定为定时器的定时时长，或者，网络设备可以将终端设备上报的参考有效时长与预设时长之和作为定时器的定时时长，该预设时长可以由协议约定。
可选的，定时器的定时时长、历史GNSS测量结果的有效时长的单位可以是毫秒、秒、时隙、符号、帧或其他单位，本申请实施例对此不做限定。
在一种实现方式中，DCI用于触发随机接入过程的情况下，终端设备在GNSS测量间隙内进行GNSS测量之后，可以发送PRACH。换言之，DCI用于触发随机接入过程的情况下，终端设备在GNSS测量间隙内进行GNSS测量后发起随机接入过程，即GNSS测量间隙的位置在PRACH的时域资源位置之前。终端设备在GNSS测量间隙内进行GNSS测量后可以得到该终端设备的位置信息，该终端设备的位置信息可以用于计算定时提前(Timing Advance，TA)量，通过准确地计算该TA量，有利于提高终端设备发送PRACH并顺利接入网络的概率。
在一种实现方式中，DCI用于调度数据的情况下，GNSS测量间隙的位置可以在该数据的时域资源位置之前，或者，该数据的时域资源位置可以在GNSS测量间隙的位置之前。换言之，DCI用于调度数据的情况下，终端设备传输数据的时序可以为：先在GNSS测量间隙内进行GNSS测量，后传输数据；或者，终端设备先传输数据，后在GNSS测量间隙内进行GNSS测量。其中，“GNSS测量间隙的位置在该数据的时域资源位置之前”表示：终端设备先在GNSS测量间隙内进行GNSS测量，后传输数据。“该数据的时域资源位置在GNSS测量间隙的位置之前”表示：终端设备先传输数据，后在GNSS测量间隙内进行GNSS测量。
其中，GNSS测量间隙为一个时域资源。在本申请实施例中，两个时域资源(如GNSS测量间隙、数据的时域资源)的位置的前后关系可通过时域资源占用的时间单元所确定。该时间单元例如可以为帧、子帧、时隙、符号或其他时域上的单位，本申请实施例不做限定。以时间单元为符号为例，GNSS测量间隙的位置、数据的时域资源位置的前后关系可通过该两个时域资源占用的第一个符号或者最后一个符号确定。
示例性的，若GNSS测量间隙占用的第一个符号的符号索引小于数据的时域资源占用的第一个符号的符号索引，则认为相对于数据的时域资源位置，GNSS测量间隙的位置更靠前。或者，若GNSS测量间隙占用的最后一个符号的符号索引小于数据的时域资源占用的第一个符号的符号索引，则认为相对于数据的时域资源位置，GNSS测量间隙的位置更靠前。或者，若GNSS测量间隙占用的最后一个符号的符号索引小于数据的时域资源占用的最后一个符号的符号索引，则认为相对于数据的时域资源位置，GNSS测量间隙的位置更靠前。其中，某符号的符号索引用于表征该符号的索引位置。需要说明的是，对于两符号(如符号1和符号2)，符号1的符号索引小于符号2的符号索引还可以描述为：符号1早于符号2。
在一种实现方式中，GNSS测量间隙占用的时间单元与数据的时域资源占用的时间单元在时域上不重叠，换言之，GNSS测量与数据传输是时分的，终端设备不会同时进行GNSS测量与数据传输。通过将数据传输与GNSS测量从时间上分开的方式，使得在终端设备进行长时间的数据传输的业务场景下，也可以执行GNSS测量，这样可以在不中断数据传输 的情况下，确保能获取终端设备准确的位置信息。对于物联网终端设备而言，GNSS测量与数据传输时分，可以降低物联网终端设备的复杂度。
在一种实现方式中，前述终端设备先在GNSS测量间隙内进行GNSS测量，后传输数据的情况下，该数据的时域资源的起始位置，可以由GNSS测量间隙的结束位置与第一时延值确定，该第一时延值为该数据的时域资源的起始位置相对该GNSS测量间隙的结束位置的时延。可选的，该数据的时域资源的起始位置为GNSS测量间隙的结束位置与该第一时延值之和。示例性的，如图6所示，若GNSS测量间隙的结束位置在子帧n，且第一时延值为k1个子帧，那么DCI所调度的数据的时域资源的起始位置在子帧n+k1。
前述终端设备先传输数据，后在GNSS测量间隙内进行GNSS测量的情况下，该数据的时域资源的起始位置，可以由DCI的时域资源的结束位置与第二时延值确定，该第二时延值为该数据的时域资源的起始位置相对该DCI的时域资源的结束位置的时延。可选的，该数据的时域资源的起始位置为DCI的时域资源的结束位置与该第二时延值之和。示例性的，如图7所示，若DCI的时域资源的结束位置在子帧n，且第二时延值为k2个子帧，那么DCI所调度的数据的时域资源的起始位置在子帧n+k2。
需要说明的是，图6中GNSS测量间隙的位置可根据DCI的时域资源位置和时间偏移量确定，该时间偏移量为GNSS测量间隙与该DCI的时域资源之间的时长，具体参见前文描述，此处不再赘述。图7中GNSS测量间隙的位置可根据DCI所调度的数据的时域资源位置和时间偏移量确定，该时间偏移量为GNSS测量间隙与该数据的时域资源之间的时长，具体参见前文描述，此处不再赘述。
可选的，第一时延值、第二时延值均可以通过前述DCI指示，或者，通过网络设备发送的第四指示信息指示，或者，由协议预定义。其中，该第四指示信息可以携带于高层信令或系统信息中。
可选的，第一指示信息、第二指示信息、第三指示信息、第四指示信息可以携带在同一信令或消息中，或者可以携带在不同的信令或消息中。示例性的，第一指示信息、第二指示信息、第三指示信息、第四指示信息携带在同一信令或消息中的情况下，GNSS测量间隙的时长、时间偏移量、定时器的定时时长可以使用同一比特信息指示，也可以使用不同的比特信息指示。
在一种实现方式中，终端设备可以处于RRC连接(RRC_Connected)态的情况下进行GNSS测量。示例性的，终端设备处于RRC_Connected态的情况下，可以接收用于触发随机接入过程的DCI，然后终端设备在处于RRC_Connected态期间在GNSS测量间隙内进行GNSS测量并得到终端设备的位置信息后，发起随机接入过程。又如，终端设备处于RRC_Connected态期间，可以接收用于调度数据的DCI，然后终端设备在处于RRC_Connected态期间先在GNSS测量间隙内进行GNSS测量并得到终端设备的位置信息，然后进行数据传输；或者，终端设备在处于RRC_Connected态期间先进行数据传输，然后在GNSS测量间隙内进行GNSS测量并得到终端设备的位置信息。
相较于只能在RRC空闲(RRC_Idle)态执行GNSS测量的方式，终端设备通过在RRC_Connected态期间执行GNSS测量，可以更好地适应更多场景。示例性的，若终端设备只能在RRC空闲(RRC_Idle)态执行GNSS测量，那么会导致终端设备无法支持长时间 的数据传输业务场景。因为终端设备需要先退出RRC_Connected态，然后进入RRC_Idle态才能执行GNSS测量，所以终端设备无法支持长时间的数据传输业务。在本申请实施例中，终端设备支持在RRC_Connected态期间执行GNSS测量，所以可以支持长时间的数据传输业务。另外，通过数据传输与GNSS测量时分的方式，可以使得数据传输与GNSS测量相互不干扰，还可以降低终端设备的复杂度。
在本申请实施例中，终端设备根据DCI的时域资源位置或根据DCI调度的数据的时域资源位置，确定GNSS测量间隙的位置，一方面可以灵活地确定GNSS测量间隙的位置。第二方面，终端设备支持在RRC_Connected态期间执行GNSS测量，使得终端设备可以支持长时间的数据传输业务。第三方面，通过数据传输与GNSS测量时分的方式，可以使得数据传输与GNSS测量相互不干扰，还可以降低终端设备的复杂度。
