具体实施方式Detailed ways
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.
目前第三代合作伙伴项目(Third Generation Partnership Project，3GPP)正在研究NTN技术，NTN技术一般采用卫星通信的方式向地面用户提供通信服务。示意性的如图1所示，在NTN***中，存在多个卫星，且每个卫星位于不同的轨道。每个卫星覆盖有一个或多个小区，终端10可以在小区内进行移动。比如，卫星01、卫星02和卫星03分别位于不同的轨道中，终端10位于卫星01覆盖的服务小区内。Currently, the Third Generation Partnership Project (3GPP) is studying NTN technology, which generally provides communication services to terrestrial users by means of satellite communication. As schematically shown in FIG. 1 , in the NTN system, there are multiple satellites, and each satellite is located in a different orbit. Each satellite covers one or more cells, and the terminal 10 can move in the cells. For example, satellite 01, satellite 02, and satellite 03 are located in different orbits, respectively, and terminal 10 is located in a serving cell covered by satellite 01.
为保证卫星的覆盖，卫星通常采用多波束覆盖地面，一个卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。由此导致两个卫星之间存在传输时延差。To ensure satellite coverage, satellites usually use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers. As a result, there is a transmission delay difference between the two satellites.
结合图1和图2，以终端10通过卫星01与第一网络设备进行网络连接为例，卫星01对应有第二网络设备。在终端10从卫星01覆盖的服务小区进入卫星02覆盖的邻小区1时，由于卫星01和卫星02之间存在传输时延差，导致第一网络设备为终端10配置的测量窗口、与终端10接收到的测量窗口存在信号延迟1； 或者，导致终端接收到的服务于第二网络设备的SSB配置窗口与实际配置的窗口存在信号延迟2。With reference to FIG. 1 and FIG. 2, it is taken as an example that the terminal 10 performs network connection with the first network device through the satellite 01, and the satellite 01 corresponds to the second network device. When the terminal 10 enters the neighboring cell 1 covered by the satellite 02 from the serving cell covered by the satellite 01, due to the transmission delay difference between the satellite 01 and the satellite 02, the measurement window configured by the first network device for the terminal 10 is different from that of the terminal 10. The received measurement window has a signal delay of 1; or, there is a signal delay of 2 between the SSB configuration window that is received by the terminal and serves the second network device and the actually configured window.
在NTN***中，存在透传载荷NTN和再生载荷NTN两种场景。其中，透传载荷只提供无线频率滤波，频率转换和放大的功能。只提供信号的透明转发，不会改变其转发的波形信号；再生载荷：除了提供无线频率滤波，频率转换和放大的功能，还可以提供解调/解码，路由/转换，编码/调制的功能。In the NTN system, there are two scenarios of transparently transmitting the payload NTN and regenerating the payload NTN. Among them, the transparent transmission load only provides the functions of radio frequency filtering, frequency conversion and amplification. It only provides transparent forwarding of the signal, and does not change the waveform signal it forwards; regeneration load: in addition to providing the functions of radio frequency filtering, frequency conversion and amplification, it can also provide the functions of demodulation/decoding, routing/conversion, coding/modulation.
示意性的，NTN网络中包括1个或多个网关，用于连接卫星和地面公共网络。其中，网关和卫星之间的通信链路为馈线链路，终端和卫星之间的通信链路为服务链路。Illustratively, the NTN network includes one or more gateways for connecting the satellite and the terrestrial public network. Among them, the communication link between the gateway and the satellite is a feeder link, and the communication link between the terminal and the satellite is a service link.
透传载荷NTN中，终端通过服务链路与卫星进行通信，网络设备通过馈线链路与网络设备进行通信。再生荷载中，还存在两个卫星之间的通信链路，该链路可以称之为星间链路。In the transparent transmission payload NTN, the terminal communicates with the satellite through the service link, and the network device communicates with the network device through the feeder link. In the regeneration load, there is also a communication link between two satellites, which can be called an inter-satellite link.
NTN的两种场景下，网络设备可以是基站，基站是一种用于为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的***中，具备基站功能的设备的名称可能会有所不同。本申请实施例中，上述为终端10提供无线通信功能的装置统称为网络设备。In the two scenarios of NTN, the network device may be a base station, and the base station is a device for providing wireless communication functions for terminals. The base station may include various forms of macro base station, micro base station, relay station, access point and so on. In systems using different radio access technologies, the names of devices with base station functions may vary. In the embodiments of the present application, the above-mentioned apparatuses that provide the terminal 10 with a wireless communication function are collectively referred to as network equipment.

The PVT information of the satellite refers to at least one of the position information, velocity information and timing information of the satellite.
步骤3022：获取测量间隔的配置信息。Step 3022: Obtain configuration information of the measurement interval.
示意性的，测量间隔(Measurement Gap)是指终端执行测量的周期。其中，测量间隔的配置信息包括但不限于如下信息中的至少一种：Illustratively, the measurement gap (Measurement Gap) refers to a period during which the terminal performs measurement. Wherein, the configuration information of the measurement interval includes but is not limited to at least one of the following information:
测量间隔长度(Measurement Gap Length，MGL)；Measurement Gap Length (MGL);

示意性的，测量间隔的配置信息是测量配置信息中的一种。测量配置信息，是指网络设备向终端发送的与测量相关的参数信息，终端根据接收到的测量配置信息进行同频测量、异频测量或异技术测量，并将测量结果上报给网络设备。示意性的，测量配置信息包括但不限于中的至少一种：测量对象(Measurement Object)、测量间隔、上报配置(Reporting Configuration)和测量标识(Measurement Identity)。Illustratively, the configuration information of the measurement interval is one type of measurement configuration information. The measurement configuration information refers to the parameter information related to the measurement sent by the network device to the terminal. The terminal performs intra-frequency measurement, inter-frequency measurement or inter-technology measurement according to the received measurement configuration information, and reports the measurement result to the network device. Illustratively, the measurement configuration information includes, but is not limited to, at least one of: a measurement object (Measurement Object), a measurement interval, a reporting configuration (Reporting Configuration), and a measurement identity (Measurement Identity).

Illustratively, the location information of the satellites corresponding to the neighboring cells is included in the configuration information of the measurement object. In an optional implementation manner, the terminal receives measurement configuration information, where the measurement configuration information includes configuration information of the measurement object and configuration information of the measurement interval, wherein the configuration information of the measurement object includes the configuration information of the satellite corresponding to the neighboring cell. location information.
示意性的，步骤3021和步骤3022可以同时执行，也可以不同时执行。Illustratively, step 3021 and step 3022 may be performed at the same time, or may not be performed at the same time.
步骤304：根据位置信息和测量间隔的配置信息，计算测量间隔的起始时间。Step 304: Calculate the start time of the measurement interval according to the location information and the configuration information of the measurement interval.
根据前文所述，测量间隔是终端执行测量的周期。因此，在终端执行测量之前，需要计算测量间隔的起始时间(Gap Staer Timing)。也即，需要计算测量周期的起始时间。According to the foregoing, the measurement interval is the period during which the terminal performs measurement. Therefore, before the terminal performs the measurement, the start time of the measurement interval (Gap Staer Timing) needs to be calculated. That is, the start time of the measurement period needs to be calculated.
在NTN场景下，由于不同轨道的卫星的传输时延不同，导致与卫星对应的服务小区和邻小区之间存在传输时延差，该传输时延差将会导致位于服务小区的终端无法执行对邻小区的测量。In the NTN scenario, due to the different transmission delays of satellites in different orbits, there is a transmission delay difference between the serving cell corresponding to the satellite and the neighboring cell. Neighboring cell measurements.
步骤304中，终端获取与邻小区对应的卫星的位置信息，根据与服务小区对应的卫星的位置信息和与邻小区对应的卫星的位置信息，通过计算可以得到服务小区和邻小区之间的传输时延差。基于服务小区和邻小区之间的传输时延差和测量间隔的配置信息，终端通过计算得到测量间隔的起始时间。随后，依据该起始时间，终端执行测量。In step 304, the terminal obtains the position information of the satellite corresponding to the adjacent cell, and according to the position information of the satellite corresponding to the serving cell and the position information of the satellite corresponding to the adjacent cell, the transmission between the serving cell and the adjacent cell can be obtained by calculation. Latency difference. Based on the transmission delay difference between the serving cell and the neighboring cell and the configuration information of the measurement interval, the terminal obtains the start time of the measurement interval through calculation. Then, according to the start time, the terminal performs measurements.
