Description

时频同步的调整方法及装置 技术领域
本公开涉及无线通信技术领域，特别涉及一种时频同步的调整方法及装置。
背景技术
在无线通信技术的研究中，卫星通信被认为是未来无线通信技术发展的一个重要方面。卫星通信是指地面上的无线电通信设备利用卫星作为中继而进行的通信。卫星通信的特点是：通信范围大；只要在卫星发射的电波所覆盖的范围内，从任何两点之间都可进行通信；不易受陆地灾害的影响(可靠性高)。卫星通信作为目前地面的蜂窝通信系统的补充，可以预见，在未来的无线通信系统中，卫星通信系统和陆地上的蜂窝通信系统会逐步的实现深度的融合，真正的实现万物智联。
对于卫星通信的场景下，由于发送端与接收端存在较长的信号传输距离，导致数据传输有较大的时延。对于存在有上下行关系的传输，终端需要基于全球导航卫星系统(Global Navigation Satellite System，GNSS)测量以及一些辅助信息来维持上行的同步。目前可通过做参考信号(Reference Signal,RS)的测量来维持时频同步，然而，仅仅依靠RS的测量无法保证时域或是频域同步的精准性。

具体实施方式
下面详细描述本公开的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
对于卫星通信的场景下，由于发送端与接收端存在较长的信号传输距离，导致数据传输有较大的时延。对于存在有上下行关系的传输，终端需要基于全球导航卫星系统(Global Navigation Satellite System，GNSS)测量以及一些辅助信息来维持上行的同步。目前可通过做参考信号(Reference Signal,RS)的测量来维持时频同步，然而，仅仅依靠RS的测量无法保证时域或是频域同步的精准性。
为此，本公开提出了一种时频同步的调整方法及装置，能够保证终端设备的时域或是频域的同步误差维持在合理的范围内，提高时域或是频域同步的精准性。
图1示出了根据本公开实施例的一种时频同步的调整方法的流程示意图。如图1所示，该方法应由终端设备执行，且可以包括以下步骤。
步骤101、接收基站发送的配置信息。
其中，配置信息中可包括用于检测基站发送的时频调整信息相关的信息。配置信息为基站通过高层信令或物理层信令承载发送的，其中高层信令可包括系统信息，无线资源控制(Radio Resource Control，RRC)信令，或是媒体访问控制(Media Access Control，MAC)的控制元素(Control Element，CE)。
步骤102、根据配置信息检测基站发送的时频调整信息。
其中，时频调整信息为时域和/或频域同步相关的调整信息，时频调整信息可以是一个绝对的调整值，如设定的预设调整值，其可包括时域预设调整值和频域预设调整值；此外，时频调整信息也可以为相对于某个参考值的调整值，比如参考值可以是相对于当前终端时域或是频域调整值的偏移值，即相当于当前时频的偏移调整值，其可包括时域偏移调整值和频域偏移调整值。对于本公开实施例，可根据配置信息在特定位置检测获取基站发送的时域和/或频域同步相关的调整信息。
步骤103、根据时频调整信息调整时域和/或频域同步。
对于本公开实施例，作为一种可选方式，实施例步骤可包括：根据预设调整值或偏移调整值，调整时域和/或频域同步。具体的，可将当前时域同步值调整至时域预设调整值和/或将当前频域同步值调整至频域预设调整值；或者，可按照时域偏移调整值调整当前时域同步的偏移值和/或按照频域偏移调整值调整当前频域同步的偏移值。通过上述基于时频调整信息对时域和/或频域的同步值调整，可以有效的保证终端的时域和/或频域的同步误差维持在合理的范围内，有效维持上行时频的同步。
在具体的应用场景中，对于存在有上下行关系的传输，终端需要基于全球导航卫星系统(Global Navigation Satellite System，GNSS)测量以及一些辅助信息来维持上行的同步。然而在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)R18标准中，当支持了传输时间比较长的业务时，GNSS信息过期的情况下，终端需要断开与网络侧的通信连接，进入到空闲(IDLE)状态，重新执行GNSS信息的测量过程。然而此种方式将无法使GNSS信息保持在生效状态，进而不能够支持终端与网络侧的持续通信，容易导致存在一定能量消耗。
有鉴于此，对于本公开实施例，作为一种可选方式，在配置信息中还可包括终端设备自身的全球导航卫星系统(Global Navigation Satellite System，GNSS)信息，相应的，终端设备可根据时频调整信息，在当前GNSS信息的生效时间内执行时域同步和/或频域同步的调整。并且，为保证终端与网络侧的持续通信，实现对时域和/或频域的闭环同步调整，终端设备可及时获取当前GNSS信息的可用时长，并在当前GNSS信息失效时，通过GNSS可用时长扩展或重新测量，确定GNSS信息的生效时间，从而使GNSS信息保持在生效状态。在具体的应用场景中，作为一种可选方式，实施例步骤可包括：接收全球导航卫星系统GNSS信息的生效时间配置信息；和/或，接收全球导航卫星系统GNSS信息的扩展时间配置信息；根据生效时间配置信息，确定当前GNSS信息的生效时间；和/或，根据扩展时间配置信息，更新当前GNSS信息的生效时间。通过此种实施方式，可降低终端设备执行GNSS信息测量的频率，降低终端设备的能量消耗。
相应的，在GNSS信息的生效时间配置信息中，可携带当前GNSS信息的可用时间的长度信息，终端设备可以基于长度信息确定自身GNSS信息的可用时间，即根据自身GNSS信息的可用时间更新GNSS信息过期时间。如图2所示，若在当前GNSS信息过期前A点处接收到GNSS信息的生效时间配置信息，GNSS信息的生效时间配置信息中指示当前GNSS信息的可用时间的长度信息为10s，则可根据该可用时间的长度信息重新确定新的GNSS过期时间点A′，在A点到A′点之间当前GNSS信息的生效时间内，终端设备与基站保持通信连接的状态(不进入IDLE状态)下，不执行GNSS信息的测量操作。此外，终端设备 还可在当前GNSS信息过期前或当前GNSS信息过期后，接收基站发送的GNSS信息的扩展时间配置信息。在GNSS信息的扩展时间配置信息中可包括是否扩展当前GNSS信息的生效时间和扩展的时长相关的信息，其中，扩展的时长相关的信息可包括当前GNSS信息扩展生效的时间长度和扩展起始时间点中的至少一项。进一步的，终端设备可在当前GNSS信息的过期时间点和/或扩展起始时间点，扩展当前GNSS信息的生效时间，生效时间的扩展长度为该时间长度。如图3所示，终端设备可在确定当前GNSS信息即将过期或已经过期的情况下，接收到基站发送的GNSS信息的扩展时间配置信息，基站的GNSS信息的扩展时间配置信息中指示了扩展起始时间点(如当前GNSS信息的过期时间点)为B，生效时间拓展的长度为b(如10s)，因此终端可在配置信息所指示的扩展起始时间点B处，进一步扩展长度为b的生效时间，进一步扩展得到新的GNSS过期时间点B′，在B点到B′点之间当前GNSS信息的生效时间内，终端设备与基站保持通信连接的状态(不进入IDLE状态)下，不执行GNSS信息的测量操作。
对于本公开实施例，作为一种可选方式，在根据时频调整信息调整时域和/或频域同步时，终端设备可在指示的时间上执行时域同步和/或频域同步的调整。相应的，实施例步骤可包括：根据时频调整信息的应用时间指示，确定时频同步的调整时间；在调整时间上执行时域同步和/或频域同步的调整。相应的，实施例步骤还可包括：接收基站发送的时频调整信息的应用时间指示。例如，根据时频调整信息的应用时间指示，确定时频同步的调整时间为距离当前在所在时域单元之后10个slot后的slot上，则终端设备可在距离当前在所在时域单元之后10个slot后的slot上开始执行时域同步和/或频域同步的调整。通过此种方式，可实现对时域同步和/或频域同步调整的应用时间设置，能够满足用户对时域同步和/或频域同步调整的个性化需求。
需要说明的是，本公开实施例可选用上述可选实施步骤的任意一种或多种可选实施步骤的组合，来调整时域和/或频域同步，例如，可根据预设调整值或偏移调整值，在当前GNSS信息的原有生效时间调整时域和/或频域同步，或者可在当前GNSS信息的扩展生效时间内，根据预设调整值或偏移调整值，调整时域和/或频域同步，或者可在当前GNSS信息的扩展生效时间内的调整时间上，根据预设调整值或偏移调整值，调整时域和/或频域同步，等等，在此不进行具体限定。
综上，根据本公开实施例提供的时频同步的调整方法，可根据基站发送的配置信息检测基站发送的时域和/或频域同步相关的调整信息，根据时域和/或频域同步相关的调整信息调整时域和/或频域同步。可以有效的保证终端的时域或是频域的同步误差维持在合理的范围内，提高时域或是频域同步的精准性。同时还可降低终端设备执行GNSS信息测量的频率，降低终端设备的能量消耗，并且满足用户对时域同步和/或频域同步调整的个性化需求。

参见图10，该方法包括如下步骤：
步骤801、基站向终端设备发送配置信息。
其中，配置信息中可包括用于检测基站发送的时频调整信息相关的信息。配置信息为基站通过高层信令或物理层信令承载发送的，其中高层信令可包括系统信息，无线资源控制(Radio Resource Control，RRC)信令，或是媒体访问控制(Media Access Control，MAC)的控制元素(Control Element，CE)。
在具体的应用场景中，作为一种可能的实现方式，基站可向终端设备发送包括第一格式、待检时域资源位置以及待检频域资源位置的配置信息，该配置信息用于在上行时间间隔内检测时频调整信令，第一格式为时频调整信令的信令格式。
作为一种可能的实现方式，基站可向终端设备发送包括第一格式以及待检频域资源位置的配置信息，该配置信息用于在上行时间间隔内的预设时域单元上检测时频调整信令，第一格式为时频调整信令的信令格式。
作为一种可能的实现方式，基站可向终端设备发送包括第二格式、待检时域资源位置以及待检频域资源位置的配置信息，该配置信息用于检测控制指令，控制指令的信息域上携带有时频调整信息，第二格式为控制指令的指令格式。
步骤802、终端设备根据配置信息检测基站发送的时频调整信息，时频调整信息为时域和/或频域同步相关的调整信息。
其中，时频调整信息为时域和/或频域同步相关的调整信息，时频调整信息可以是一个绝对的调整值，如设定的预设调整值，其可包括时域预设调整值和频域预设调整值；此外，时频调整信息也可以为相对于某个参考值的调整值，比如参考值可以是相对于当前终端时域或是频域调整值的偏移值，即相当于当前时频的偏移调整值，其可包括时域偏移调整值和频域偏移调整值。对于本公开实施例，可根据配置信息在特定位置检测获取基站发送的时域和/或频域同步相关的调整信息。
在具体的应用场景中，作为一种可选实施例，当配置信息为包括第一格式、待检时域资源位置以及待检频域资源位置的配置信息时，终端设备可在上行时间间隔内检测时频调整信令，时频调整信令中包含时频调整信息。即可在上行时间间隔内的特定时域资源和/或特定频域资源位置处，实现对时频调整信令的检测，进而获取到时频调整信令中包含的时频调整信息。其中，时频调整信令可以是高层信令如无线资源控制(Radio Resource Control，RRC)信令，媒体访问控制(Media Access Control，MAC)的控制元素(Control Element，CE)或是物理层信令如下行控制信令(Downlink Control Information，DCI)。
在具体的应用场景中，作为一种可选实施例，当配置信息为包括第一格式以及待检频域资源位置的配置信息时，终端设备可在上行时间间隔内的预设时域单元上检测时频调整信令，时频调整信令中包含时频调整信息。即可在上行时间间隔内的预设时域单元上如每个时域单元上实现对时域调整信令的检测，进而获取到携带时频调整信息的信令中包含的时频调整信息。鉴于在该配置信息中可包含待检频域资源位置，故可在上行时间间隔的预设时域单元上的特定频域资源位置处，实现对时频调整信令的检测，进而获取到时频调整信令中包含的频域调整信息。其中，时频调整信令可以是高层信令如RRC信令，MAC CE或是物理层信令如DCI；预设时域单元可以是上行时间间隔内的每一个时域单元(如子帧)。
在具体的应用场景中，作为一种可选实施例，当配置信息为包括第二格式、待检时域资源位置以及待检频域资源位置的配置信息时，终端设备可在控制指令的信息域上检测基站发送的时频调整信息。其中，控制指令为调度数据传输的指令；信息域的位置和长度信息是预先定义的或是接收基站发送的配置信息确定的。
步骤803、终端设备根据时频调整信息调整时域和/或频域同步。
对于本公开实施例，作为一种可选方式，实施例步骤可包括：根据预设调整值或偏移调整值，调整时域和/或频域同步。具体的，可将当前时域同步值调整至时域预设调整值和/或将当前频域同步值调整至频域预设调整值；或者，可按照时域偏移调整值调整当前时域同步的偏移值和/或按照频域偏移调整值调整当前频域同步的偏移值。通过上述基于时频调整信息对时域和/或频域的同步值调整，可以有效的保证终端的时域和/或频域的同步误差维持在合理的范围内，有效维持上行时频的同步。
在具体的应用场景中，对于存在有上下行关系的传输，终端需要基于全球导航卫星系统(Global Navigation Satellite System，GNSS)测量以及一些辅助信息来维持上行的同步。然而在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)R18标准中，当支持了传输时间比较长的业务时，GNSS信息过期的情况下，终端需要断开与网络侧的通信连接，进入到空闲(IDLE)状态，重新执行GNSS信息的测量过程。然而此种方式将无法使GNSS信息保持在生效状态，进而不能够支持终端与网络侧的持续通信，容易导致存在一定能量消耗。
有鉴于此，对于本公开实施例，作为一种可选方式，在配置信息中还可包括终端设备自身的全球导航卫星系统(Global Navigation Satellite System，GNSS)信息，相应的，终端设备可根据时频调整信息，在当前GNSS信息的生效时间内执行时域同步和/或频域同步的调整。并且，为保证终端与网络侧的持续通信，实现对时域和/或频域的闭环同步调整，终端设备可及时获取当前GNSS信息的可用时长，并在当前GNSS信息失效时，通过GNSS可用时长扩展或重新测量，确定GNSS信息的生效时间，从而使GNSS信息保持在生效状态。在具体的应用场景中，作为一种可选方式，实施例步骤可包括：接收全球导航卫星系统GNSS信息的生效时间配置信息；和/或，接收全球导航卫星系统GNSS信息的扩展时间配置信息；根据生效时间配置信息，确定当前GNSS信息的生效时间；和/或，根据扩展时间配置信息，更新当前GNSS信息的生效时间。
在具体的应用场景中，GNSS信息的生效时间配置信息里可携带当前GNSS信息的可用时间的长度信息，进一步的，终端设备在接收到基站发送的GNSS信息的生效时间配置信息后，可以基于长度信息确定自身GNSS信息的可用时间，即根据自身GNSS信息的可用时间更新新的GNSS信息过期时间，以此保证终端设备在新的GNSS信息过期时间之前，与基站保持通信连接的状态(不进入IDLE状态)下，不执行GNSS信息的测量操作。在GNSS信息的扩展时间配置信息中可包括是否扩展当前GNSS信息的生效时间和扩展的时长相关的信息，其中，扩展的时长相关的信息可包括当前GNSS信息扩展生效的时间长度和扩展起始时间点中的至少一项。进一步的，终端设备在接收到基站发送的GNSS信息的扩展时间配置信息后，可在当前GNSS信息的过期时间点和/或扩展起始时间点，扩展当前GNSS信息的生效时间，生效时间的扩展长度为该时间长度，以此保证终端设备在新的GNSS信息过期时间之前，与基站保持通信连接的状态(不进入IDLE状态)下，不执行GNSS信息的测量操作。通过此种实施方式，可降低终端设备执行GNSS信息测量的频率，降低终端设备的能量消耗。
对于本公开实施例，作为一种可选方式，在根据时频调整信息调整时域和/或频域同步时，终端设备可在指示的时间上执行时域同步和/或频域同步的调整。相应的，实施例步骤可包括：根据时频调整信息的应用时间指示，确定时频同步的调整时间；在调整时间上执行时域同步和/或频域同步的调整。相应的，实施例步骤还可包括：接收基站发送的时频调整信息的应用时间指示。例如，根据时频调整信息的应用时间指示，确定时频同步的调整时间为距离当前在所在时域单元之后10个slot后的slot上，则终端设备可在距离当前在所在时域单元之后10个slot后的slot上开始执行时域同步和/或频域同步的调整。通过此种方式，可实现对时域同步和/或频域同步调整的应用时间设置，能够满足用户对时域同步和/或频域同步调整的个性化需求。
需要说明的是，本公开实施例可选用上述可选实施步骤的任意一种或多种可选实施步骤的组合，来调整时域和/或频域同步，例如，可根据预设调整值或偏移调整值，在当前GNSS信息的原有生效时间调整时域和/或频域同步，或者可在当前GNSS信息的扩展生效时间内，根据预设调整值或偏移调整值，调整时域和/或频域同步，或者可在当前GNSS信息的扩展生效时间内的调整时间上，根据预设调整值或偏移调整值，调整时域和/或频域同步，等等，在此不进行具体限定。
通过应用本实施例提供的时频同步的调整方法，可根据基站发送的配置信息检测基站发送的时域和/或频域同步相关的调整信息，根据时域和/或频域同步相关的调整信息调整时域和/或频域同步。可以有效的保证终端的时域或是频域的同步误差维持在合理的范围内，提高时域或是频域同步的精准性。同时还可降低终端设备执行GNSS信息测量的频率，降低终端设备的能量消耗，并且满足用户对时域同步和/或频域同步调整的个性化需求。
