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。
移动网络通信技术在现实生活中应用场景的边界在不断扩展，例如面向未来的增强现实(Augmented Reality，AR)、虚拟现实(Virtual Reality，VR)、以及更多新型互联网应用(诸如车联网、物联网等)等应用场景的涌现，各应用场景对于网络通信质量、时延容忍的要求不一。例如eMBB业务类型主要的要求侧重在大带宽，高速率等方面；URLLC业务类型主要的要求侧重在较高的可靠性以及低的时延方面；mMTC业务类型主要的要求侧重在大的连接数方面。因此新一代的无线通信系统需要灵活和可配置的设计来支持多种业务类型的传输。
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。卫星通信系统由卫星部分和地面部分组成。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，可以有以下的好处：
1)延伸覆盖：对于目前蜂窝通信系统无法覆盖或是覆盖成本较高的地区，如海洋，沙漠，偏远山区等，可以通过卫星通信来解决通信的问题。
2)应急通信：在发生灾难如地震等的极端情况下导致蜂窝通信的基础设施不可用的条件下，使用卫星通信可以快速的建立通信连接。
3)提供行业应用：比如对于长距离传输的时延敏感业务，可以通过卫星通信的方式来降低业务传输的时延。
因此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。
在卫星通信的场景下，由于发送端与接收端之间存在较长的信号传输距离，导致上下行时间有较大的偏差。对于存在有上下行关系的传输，目前的标准化讨论中确定了引入Koffset的参数来补偿传输时 延。Koffset可以应用在多种操作下，比如：DCI调度的PUSCH传输；HARQ反馈信息的传输以及MAC CE的传输等。
在卫星通信的场景下，终端需要获知自己的位置信息以便于进行上行同步的补偿。对于IoT UE而言，目前不支持cellular模块和GNSS模块同时工作，当终端的GNSS信息过期之后，终端需要进入到IDLE状态，重新执行GNSS的测量。在现有的方法中，可以支持基站触发终端执行非周期的GNSS测量机制。然而，当终端无法收到基站发送的触发命令时，终端可能无法执行GNSS的测量。
为此，本公开提出了一种定位测量方法、装置、通信设备及存储介质，旨在提供一种应用于卫星通信系统的用于GNSS测量的方法，可以保证终端及时执行GNSS操作，避免由于GNSS失效导致的额外的功率消耗。
可以理解的是，本公开提供的方案可以应用于卫星接入网络，特别地，应用于UE通过卫星接入网络接入核心网的通信场景，包括但不限于5G核心网及支持其后续通信技术的核心网，诸如长期演进技术(LTE)、第五代移动通信技术演进(5G-advanced)、第六代移动通信技术(Sixth Generation，6G)等，在本公开中不予限制。
本公开所描述的包括但不限于智能终端设备、蜂窝电话、无线设备、手持机、移动单元、车辆、车载设备等，本公开不予限制。
本公开实施例中的网络设备是网络侧的一种用于发射或接收信号的实体。例如，网络设备可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。在本公开的实施例中，以网络设备为gNB为例。
下面结合附图对本公开所提供的方案进行详细介绍。
图1示出了根据本公开实施例的一种定位测量方法的流程示意图。该方法由用户设备(User Equipment，UE)执行，具体地，UE可以是IoT UE。
如图1所示，该方法可以包括以下步骤。

在本公开的实施例中，时间窗口的配置信息或者定时器的配置信息用于指示GNSS到期时间相关的信息，例如，可以直接指示GNSS到期时间，也可以指示用于确定GNSS到期时间的信息。
在本公开的实施例中，时间窗口的配置信息或者定时器的配置信息可以是预先定义的，也可以是UE通过接收网络设备或其他设备发送的信令而获得的，其中，该信令可以是高层信令，例如RRC信令或MAC CE信令等，也可以是物理层信令，在本公开中不予限制。
S102，基于时间窗口的配置信息或者定时器的配置信息，执行GNSS测量。
在本公开的实施例中，UE可以基于所确定的时间窗口的配置信息或者定时器的配置信息，来确定是否执行GNSS测量、何时执行GNSS测量。换言之，通过时间窗口或定时器的配置信息，UE能够确 定执行GNSS测量的具体时间，从而保证终端执行GNSS测量的及时性，避免由于GNSS失效导致的额外功率和资源消耗。
综上，根据本公开的方案，UE可以确定时间窗口的配置信息或者定时器的配置信息，并基于该时间窗口的配置信息或者定时器的配置信息执行GNSS测量，从而保证终端执行GNSS测量的及时性，避免由于GNSS失效导致的额外功率和资源消耗。
关于图1所示实施例的实现，本公开提供两种可选方式，下面分别通过图2和图3对两种方式进行详述。
图2示出了根据本公开实施例的一种定位测量方法的流程示意图。该方法可以由UE执行，基于图1所示实施例，本实施例针对根据时间窗口的配置信息进行GNSS测量的方案，如图2所示，该方法可以包括以下步骤。
S201，确定时间窗口的配置信息。
在本公开的实施例中，该步骤具体包括：确定预定义的时间窗口的配置信息，或者从网络设备或其他设备发送的高层信令或物理层信令中确定时间窗口的配置信息。换言之，时间窗口的配置信息可以是预先定义的，也可以是UE通过接收网络设备或其他设备发送的信令而获得的，其中，该信令可以是高层信令，也可以是物理层信令，在本公开中不予限制。
具体地，在一些可选实施例中，时间窗口的配置信息可以是网络设备显式发送给UE的，例如，通过系统消息、UE专属的无线资源控制(Radio Resource Control，RRC)信令、媒体接入控制控制元素(Media Access Control Control Element，MAC CE)信令、物理层信令(例如下行控制信息(Downlink Control Information，DCI))中任一项发送的。换言之，网络设备向UE发送系统消息、UE专属的RRC信令、MAC CE信令或DCI信令时，在其中携带上述时间窗口的配置信息，从而发送给UE。
在一些可选实施例中，网络设备可以向UE发送物理层信令(例如下行控制信息(Downlink Control Information，DCI))，物理层信令包括信息域值，信息域值用于辅助UE确定时间窗口的配置。在该实施例中，UE可以根据基站指示的信息域值以及信息阈值与时间窗口的配置之间的对应关系，确定时间窗口的配置。可以理解的是，上述对应关系可以是预先定义在UE中，也可以由基站通知给UE。
在上述两种可选实施例中，时间窗口的配置信息可能为多个，即，基站可以向UE指示多个时间窗口的配置信息，UE可以进行选择，在本公开中不予限制。
在本公开的实施例中，时间窗口的配置信息至少包括时间窗口的长度信息，时间窗口用于指示UE的GNSS信息到期前的时间长度。换言之，时间窗口用于指示终端GNSS信息过期之前的一段时间长度。
S202，在时间窗口内发送GNSS测量请求。

在一种可选实施方式中，GNSS测量请求包括GNSS指示信息，GNSS指示信息包括用于确定GNSS到期时间相关的信息。换言之，GNSS测量请求中包含了终端GNSS相关的指示信息，指示信息中包含用于确定GNSS的到期时间相关的信息。
在另外一种实现方式下，GNSS测量请求中包含是否请求GNSS测量的指示信息，指示信息可以是显示携带或是隐式携带的。
例如，在显示携带的情况下，终端在PUSCH或是PUCCH上使用1bit的信息指示是否请求GNSS测量，比如“1”代表请求GNSS测量；“0”代表不需要请求GNSS测量。
再例如，在隐式携带的情况下，可以预先定义是否请求GNSS测量与现有的传输的对应关系，对应关系可以是现有的导频或是数据传输的传输方式包括时频域位置、加扰序列等信息域是否请求GNSS测量的对应关系。对应关系是预先定义的或是接收网络设备或其他设备的配置信息确定的。
S203，响应于在预设时间段内接收到网络设备发送的触发GNSS测量的指令，执行GNSS测量；响应于在预设时间段内未接收到指令，在GNSS到期时间经过后进入空闲态。
在本公开的实施例中，UE可以在预设时间段内检测网络设备或其他设备发送的触发GNSS测量的指令，该预设时间段可以是终端发送GNSS测量请求之后预定义的时间，该预设时间段可以是预先定义的，也可以是接受网络设备或其他设备的配置信息确定的，在本公开中不予限制。
如在该预设时间段内接收到网络设备或其他设备发送的触发GNSS测量的指令，则UE按照指令执行GNSS测量；如在该预定时间段内没有接收到触发GNSS测量的指令，则UE在GNSS信息过期后，进入IDLE状态。
可以理解的是，在一种可选实施例中，UE可以在接收到网络设备发送的触发GNSS测量的指令就执行GNSS测量，而不设置预设时间段。在一种可能的实施例中，如果UE在GNSS过期之前仍没有接收到触发GNSS测量的指令，可以直接执行GNSS测量。
在本公开的一种可选实施方式中，UE还可以在完成GNSS测量之后，向网络设备或其他设备上报新的GNSS可用长度的信息，在本公开中不予限制。
综上，根据本公开的方案，UE可以确定时间窗口的配置信息，并基于该时间窗口的配置信息，在该时间窗口内发送GNSS测量请求，响应于在预设时间段内接收到网络设备发送的触发GNSS测量的指令执行GNSS测量，从而保证终端执行GNSS测量的及时性，避免由于GNSS失效导致的额外功率和资源消耗。

可以理解的是，定时器启动之后、定时器超时之前的时间期间的长度可以小于或等于GNSS到期的时间长度，即，UE可以在GNSS到期之前执行GNSS测量。
S304，在时间期间内完成了GNSS测量，上报新的GNSS可用长度的信息；在时间期间内未完成GNSS测量，在GNSS到期时间经过后进入空闲态。
在本公开的一些实施例中，如果UE在定时器超时之前完成了GNSS测量，则UE可以向网络设备或其他设备上报新的GNSS可用长度的信息，如果UE在定时器超时之前未完成GNSS测量，则UE在GNSS信息过期后进入IDLE状态。
在本公开的一些可选实施例中，该方法还包括：在时间期间内，不执行下行控制信令的监测、上下行数据的接收、信道测量中的至少一项。换言之，在UE执行GNSS测量操作时，UE不执行任何下行控制信令的检测，不执行上下行数据的接收，不执行信道测量等操作。
综上，根据本公开的方案，UE可以确定定时器的配置信息，并基于该定时器的配置信息，在定时器的启动条件满足时启动定时器，并在定时器启动后、定时器超时前执行GNSS测量，从而保证终端执行GNSS测量的及时性，避免由于GNSS失效导致的额外功率和资源消耗。
