Description

A measurement processing method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on December 14, 2023, with application number 202311728046.0 and application name “A measurement and processing method and device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of mobile communications, and in particular to a measurement processing method and apparatus. Background Art

[0003] A non-terrestrial network (NTN) refers to a network that uses radio frequency resources on platforms such as satellite platforms, drone platforms, or high-altitude communication platforms to provide communication services.

[0004] In current non-terrestrial communication networks, when a user device switches from a serving satellite to a neighboring satellite or reselects a cell, the user device can measure the synchronization signal block (SSB) of the neighboring satellite. During the SSB measurement process, when the user device is in the overlapping coverage area of ​​the serving satellite and the neighboring satellite, the user device also needs to measure all SSBs of the neighboring satellite for a complete cycle to determine the optimal SSB. However, due to the large coverage area of ​​the neighboring satellite and the large number of SSB beams in the complete cycle of the adjacent satellite, the measurement overhead of the user device is large. Summary of the Invention

[0005] Embodiments of the present application provide a measurement processing method, enabling a user device to determine a start time for measuring a synchronization signal block (SSB) of an adjacent satellite based on a first parameter transmitted by a serving satellite, thereby reducing the user device's measurement overhead. Embodiments of the present application also provide a measurement processing apparatus, electronic device, computer-readable storage medium, and computer program product corresponding to the measurement processing method.

[0006] In the first aspect, an embodiment of the present application provides a measurement processing method, which can be executed by a user device, or by a component of the user device, such as a processor, chip or chip system of the user device, or by a logic module or software that can realize all or part of the functions of the user device. The method provided in the first aspect includes: the user device receives a first parameter sent by a first network device, the first network device is such as a service satellite, the first parameter includes a measurement timing configuration SMTC parameter based on a synchronization signal block, the first parameter is determined based on first configuration information, the first configuration information is used to configure the synchronization signal block SSB index of the second network device in at least one area, the second network device is such as an adjacent satellite, and at least one area includes the coverage area of ​​the second network device. The user device calculates the measurement start time based on the first parameter, and the measurement start time is used to indicate the time when the user device starts measuring the SSB to be measured of the second network device. When the user device switches from the first network device to the second network device, the user device measures the SSB to be measured of the second network device based on the measurement start time.

[0007] In the embodiment of the present application, the user equipment can determine the measurement start time for measuring the SSB to be measured of the second network device based on the first parameter sent by the first network device, so that the user equipment only needs to start measuring the SSB to be measured of the second network device at the determined measurement start time, thereby reducing the number of SSBs to be measured of the second network device that the user equipment needs to measure, and reducing the SSB measurement overhead of the user equipment during the switching process from the first network device to the second network device.

[0008] In one possible implementation, the first parameter includes a physical cell identifier PCI and an offset time, and the first configuration information includes: a wave position number of at least one area, a mapping relationship between the wave position number and the SSB index of the second network device, and at least one area also includes an overlapping coverage area of ​​the first network device and the second network device.

[0009] In the embodiment of the present application, the first parameter received by the user equipment includes the offset time. The user equipment can calculate the measurement start time based on the offset time in the first parameter, thereby improving the feasibility of the user equipment in determining the measurement start time and further reducing the measurement overhead of the user equipment.

[0010] In one possible implementation, the bias time includes a first bias time. In the process of the user equipment calculating the measurement start time based on the first parameter, the user equipment determines the measurement start time based on the SSB of the first network device and the first bias time. The SSB of the first network device is the SSB corresponding to the area where the user equipment is currently located.

[0011] In an embodiment of the present application, the user equipment can use the SSB corresponding to the area where the user equipment is currently located as a reference and calculate the measurement start time based on the first bias time, thereby improving the feasibility of the user equipment in determining the measurement start time and reducing the measurement overhead of the user equipment on the SSB to be measured by the second network device.

[0012] In one possible implementation, the bias time includes a second bias time. In the process of the user equipment calculating the measurement start time based on the first parameter, the user equipment determines the measurement start time based on the start time of the measurement period and the second bias time. The measurement period is a measurement period shared by the SSB of the first network device and the SSB to be measured of the second network device.

[0013] In the embodiment of the present application, the user equipment can use the start time of the measurement period as a reference and calculate the measurement start time based on the second bias time, thereby improving the feasibility of the user equipment in determining the measurement start time and reducing the measurement overhead of the user equipment on the SSB to be measured by the second network device.

[0014] In the second aspect, an embodiment of the present application provides a measurement processing method, which can be executed by a network device, or by a component of the network device, such as a processor, chip or chip system of the network device, or by a logic module or software that can realize all or part of the network device function. The method provided in the second aspect includes: a first network device obtains a first parameter, the first network device is such as a service satellite, the first parameter is determined based on first configuration information, the first configuration information is used to configure the synchronization signal block SSB index of the second network device in at least one area, the second network device is such as an adjacent satellite, and at least one area includes the coverage area of ​​the second network device. The first network device sends a first parameter to the user equipment, and the first parameter is used to determine the measurement start time for measuring the synchronization signal block SSB to be measured of the second network device.

[0015] In the embodiment of the present application, the first network device can obtain the first parameter by interacting with the second network device and send the first parameter to the user device, so that the user device calculates the measurement start time based on the first parameter and only needs to start the measurement of the SSB to be measured of the second network device at the measurement start time, thereby reducing the number of SSBs to be measured of the second network device that the user device needs to measure, and reducing the SSB measurement overhead of the user during the switching process from the first network device to the second network device.

[0016] In one possible implementation, the first parameter includes a physical cell identifier PCI and an offset time, and the first configuration information includes: the wave position number of at least one area, a mapping relationship between the wave position number and the SSB index of the second network device, and at least one area also includes an overlapping coverage area of ​​the first network device and the second network device.

[0017] In an embodiment of the present application, the first configuration information of the adjacent satellite may also be the wave position number of the overlapping coverage area of ​​the first network device and the second network device, and the mapping relationship between the wave position number and the SSB index of the second network device, so that the first network device does not need to determine the overlapping coverage area with the second network device, thereby improving the efficiency of the first network device in obtaining the first parameter based on the first configuration information.

[0018] In one possible implementation, during the process of the first network device acquiring the first parameter, the first network device receives the first configuration information sent by the second network device, and the first network device determines the first parameter based on the first configuration information. Specifically, the first network device determines the wavenumber corresponding to the location area of ​​the user equipment, and determines the SSB index of the second network device corresponding to the user's location area based on the wavenumber. The first network device determines the SSB index and the SSB index adjacent to the SSB index as the SSB to be tested. The first network device determines the first parameter based on the SSB index of the first network device corresponding to the user equipment and the SSB index to be tested of the second network device.

[0019] In the embodiment of the present application, the first network device can calculate the first parameter based on the first configuration information sent by the second network device, thereby improving the feasibility of the first network device obtaining the first parameter. At the same time, the first network device and the second network device only need one interaction to calculate the first parameter, thereby improving the interaction efficiency between the first network device and the second network device.

[0020] In one possible implementation, when the first network device obtains the first parameter, the first network device receives the first parameter sent by the second network device, that is, the second network device can calculate the first parameter, and the first network device can directly obtain the first parameter from the second network device.

[0021] In the embodiment of the present application, the first network device directly receives the first parameter sent by the second network device, thereby improving the feasibility of the first network device obtaining the first parameter.

[0022] In one possible implementation, before the first network device receives the first parameter sent by the second network device, the first network device sends second configuration information to the second network device, where the second configuration information is used to determine the first parameter. The second configuration information includes a mapping relationship between the wave number of the area covered by the first network device, the wave number of the area covered by the first network device, and the SSB index of the first network device.

[0023] In the embodiment of the present application, the second network device can calculate the first parameter based on the second configuration information sent by the first network device, and directly send the first parameter to the first network device, thereby improving the accuracy of the first parameter.

[0024] In a possible implementation, when the first configuration information changes, the first network device updates the first parameter based on the first configuration information, and sends the updated first parameter to the user equipment.

[0025] In the embodiment of the present application, the first network device can update the first parameter based on the changed configuration information, thereby improving the accuracy of the first parameter and further improving the accuracy of the measurement start time determined by the user equipment.

[0026] In one possible implementation, when the second configuration information changes, the first network device sends the changed second configuration information to the second network device. The second network device updates the first parameter based on the changed second configuration information and sends the updated first parameter to the first network device.

[0027] In an embodiment of the present application, the first network device can send the changed second configuration information to the second network device, so that the second network device can calculate the first parameter based on the changed second configuration information, thereby improving the accuracy of the first parameter and further improving the accuracy of the measurement start time determined by the user equipment.

The processing unit is also used to measure the SSB to be measured of the second network device based on the measurement start time.

[0029] In one possible implementation, the first parameter includes a physical cell identifier PCI and an offset time, and the first configuration information includes: a wave position number of at least one area, a mapping relationship between the wave position number and the SSB index of the second network device, and at least one area also includes an overlapping coverage area of ​​the first network device and the second network device.

[0030] In one possible implementation, the bias time includes a first bias time, and the processing unit is specifically used to determine the measurement start time based on the SSB of the first network device and the first bias time, where the SSB of the first network device is the SSB corresponding to the area where the user device is currently located.

[0031] In one possible implementation, the bias time includes a second bias time, and the processing unit is specifically used to determine the measurement start time based on the start time of the measurement period and the second bias time, where the measurement period is a measurement period shared by the SSB of the first network device and the SSB to be measured of the second network device.

[0055] An embodiment of the present application provides a method and apparatus for interacting with measurement information, for reducing the measurement overhead of synchronization signal block measurements performed by a user device.

[0056] The terms "first," "second," "third," "fourth," and the like (if any) in the specification and claims of this application and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0057] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0058] First, some terms involved in the embodiments of the present application are introduced to facilitate those skilled in the art to understand the technical solutions.

[0059] A synchronization signal block (SSB) is a signal with a specific structure in a frequency domain that is used by user devices to synchronize and locate base stations at the physical layer. Each base station has unique identification information in the SSB. User devices can detect and identify nearby base stations by decoding the SSB identification information. They use the SSB for time synchronization and select the appropriate cell for connection.

[0060] SSB-based measurement timing configuration (SMTC) uses synchronization signal blocks for measurement and timing. By properly configuring SMTC parameters, the user equipment can effectively measure and time the SSB signals of surrounding cells, allowing the user equipment to select the appropriate access cell.

[0061] In order to make the technical solution of the present application clearer and easier to understand, the system architecture of the present application is introduced below with reference to the accompanying drawings.

[0062] Please refer to Figure 1a, which is a schematic diagram of the system architecture of a measurement processing system provided in an embodiment of the present application. In the example shown in Figure 1a, measurement processing system 10 is a non-terrestrial communication network system. Measurement processing system 10 includes user equipment 100, network equipment 200, and a core network 300. The specific functions of each component of measurement processing system 10 are described below.

[0063] User device 100 refers to a mobile communication device used by an end user, also known as a terminal device. User device 100 has wireless transceiver capabilities and is used to communicate with network device 200. User device 100 can be a mobile phone, tablet computer, computing device with wireless transceiver capabilities, virtual reality (VR) device, augmented reality (AR) device, in-vehicle device, etc. User device 100 can also be a wireless terminal used in industrial control, telemedicine, smart grid, transportation safety, smart city, or smart home.

[0064] The embodiments of the present application do not limit the deployment method of the user equipment 100. The user equipment 100 can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted, etc. It can also be deployed on the water, such as a terminal device on a ship, and can also be deployed in the air, such as a terminal device in a drone or a terminal device in a balloon.

[0065] The network device 200 may be a device with wireless transceiver functions. The network device 200 is used to provide wireless coverage for the user equipment 100 and connect the user equipment 100 to the core network 203. The network device 200 may be a base station in a non-terrestrial network, for example, an evolved base station in LTE carried on a satellite, a base station or transceiver point in 5G NR, and a base station subsequently evolved by 3GPP, including a macro base station, a micro base station, a pico base station, a small base station, or a relay station. The network device 200 may also be a wireless access node, a wireless relay node, or a wireless backhaul node in a WiFi system.

[0066] In the embodiment of the present application, network device 200 includes a first network device and a second network device. The first network device refers to a network device that has established a connection with user device 100, and the second network device refers to a network device that the user device needs to perform synchronization signal block measurement upon handover from the first network device. When network device 200 is a satellite base station, the first network device is a serving satellite, and the second network device is an adjacent satellite. The serving satellite is a satellite currently providing service to user device 100, also known as a local satellite. An adjacent satellite is a satellite adjacent to the serving satellite, also known as a neighboring satellite.

[0067] The satellite in the embodiment of the present application can be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite or a geostationary earth orbit (GEO) satellite, without specific limitation.

[0068] It is understandable that, in addition to being a satellite base station, the network device 200 may also be a balloon station, an unmanned aerial vehicle (UAV) platform, or a high altitude platform station (HAPS), etc., without specific limitation.

[0069] The core network 300 is responsible for processing and managing core functions and services in the mobile communication system, including completing registration, connection, and session management functions. The core network 300 includes modules such as the network exposure function (NEF), the policy and charging function (PCF), the session management function (SMF), and the user plane function (UPF).

[0070] The Network Exposure Function (NEF) exposes the services and capabilities of 3GPP network functions to application functions (AFs), allowing AFs to provide information to 3GPP network functions. The Policy and Charging Function (PCF) manages charging and Quality of Service (QoS) policies. The Session Management Function (SMF) manages session management functions such as IP address allocation for user devices, UPF selection, and charging and QoS policy control. The User Plane Function (UPF) performs user-plane data forwarding and generates call records based on traffic volume.

[0071] Please refer to Figure 1b, which is a schematic diagram of an application scenario of a measurement processing method provided in an embodiment of the present application. In the example shown in Figure 1b, the application scenarios of the measurement processing system 10 include transparent forwarding scenarios and regeneration mode scenarios. Among them, in the transparent forwarding scenario, the network device 200 plays the role of frequency conversion forwarding, that is, the network device 200 amplifies and forwards the received signal without performing any processing or decoding on the signal. For example, in the example transparent forwarding scenario shown in (a) of Figure 1b, the satellite receives the radio frequency signal of the user equipment from the ground station and forwards the radio frequency signal directly to the ground receiving station through the satellite without performing any processing or operation on the signal. Among them, the ground receiving station includes a non-3GPP interworking function (Non-3GPP InterWorking Function, N3IWF) component, a satellite ground station and a gNB base station. The N3IWF component is used to manage the connection between the access network and the core network. The satellite can forward radio frequency signals based on a variety of radio protocols, such as forwarding radio frequency signals based on a non-3GPP radio protocol or an NR radio protocol, without specific limitation.

[0072] In the regeneration mode scenario, after receiving a signal, network device 200 decodes, processes, and re-encodes it before transmitting it. In this case, network device 200 includes a gNB device or a digital processing unit (DU). For example, in the example regeneration mode scenario shown in (b) of Figure 1b, a satellite receives a radio frequency signal from a ground user device, then performs demodulation, noise reduction, and error correction on the radio frequency signal to regenerate a compensation signal. This compensation signal is then retransmitted by the satellite via the F1 interface to a ground receiving station, which includes a gNB base station or a centralized unit (CU). The F1 interface is an Internet Protocol (IP)-based protocol interface that typically uses the physical layer protocol of the satellite link as the transmission medium, such as a Ka-band or Ku-band satellite signal.

[0073] In the examples shown in Figure 1b(a) and Figure 1b(b), the NG interface is the information exchange interface between the ground receiving station and the core network. The NG interface includes the N2 interface and the N3 interface, where the N2 interface is the control plane interface and the N3 interface is the user plane interface. The N6 interface is the interface between the core network and the data network.

[0074] Based on the measurement processing system 10 shown in FIG1a , the present application further provides a measurement processing method. The measurement processing method provided in the embodiment of the present application is described below in conjunction with an embodiment.

[0075] Please refer to Figure 2a, which is a flow chart of a method for interacting with measurement information provided in an embodiment of the present application. In the example shown in Figure 2a, the method includes the following steps:

[0076] 201. The first network device obtains a first parameter, where the first parameter is determined based on first configuration information, and the first configuration information is used to configure a synchronization signal block SSB index of a second network device in at least one area.

[0077] The first network device obtains a first parameter, which includes a measurement timing configuration SMTC4 parameter based on the synchronization signal block. The SMTC4 parameter is used to determine the starting measurement time of the user equipment for the synchronization signal block SSB. The first parameter is determined based on first configuration information, wherein the first configuration information is used to indicate the configuration of the synchronization signal block SSB index of the second network device in at least one area, and the at least one area includes the coverage area of ​​the second network device.

[0078] It should be noted that the SMTC4 parameter is a measurement timing configuration parameter defined in the New Radio NR protocol. The NR protocol defines four measurement timing configuration parameters, including SMTC1, SMTC2, SMTC3, and SMTC4. Among them, the SMTC1 parameter is the main measurement timing configuration parameter, including periodicity, offset time, and duration. The periodicity determines the frequency of the user equipment measuring the synchronization signal block SSB, the offset time is used to determine the starting time position of the user equipment measuring the SSB, and the duration is used to determine the time window length of the user equipment measuring the SSB.

[0079] The SMTC2 parameter is a secondary measurement timing configuration parameter. It primarily includes a cell list (pci-list) and a period. Compared to the SMTC1 parameter, the SMTC2 parameter is a measurement timing configuration parameter for performing SSB measurements on a specific cell. The period in the SMTC2 parameter is generally shorter than the period in the SMTC1 parameter, and it shares the same offset time and duration as the SMTC1 parameter.

[0080] The SMTC3 parameter is used to configure the measurement timing parameters in the integrated access and backhaul (IAB) scenario. The SMTC3 parameter separately configures the period, offset time, duration, and cell list. The SMTC3 parameter specifies the SSB index to be measured.

[0081] The SMTC4 parameter is a measurement timing configuration parameter used in non-terrestrial communication network (NTN) scenarios. In NTN scenarios, due to the different delays from different network devices (such as satellites) to user equipment, if the first network device and the second network device use the same offset time configuration, the SSB of the second network device may not be measured within the configured duration, resulting in measurement failure.

[0082] Therefore, the SMTC4 parameter primarily includes a list of physical cell identifiers (PCIs) and an offset time. The PCI list is used to determine the cells in which the user equipment performs SSB measurements, and each PCI list corresponds to a type of offset time. The SMTC4 parameter allows configuration of three PCI lists.

[0083] Compared with the SMTC1 parameters, the network equipment side can calculate the SSB arrival delay of different network devices based on the position of each network device (such as satellite) and the position of the user equipment, and configure the corresponding PCI list and offset time in the SMTC4 parameters to ensure that the SSB of the network device can be detected by the user equipment at the corresponding time position. As for the period and duration, the SMTC4 parameters and the SMTC1 parameters are multiplexed.

[0084] In an example of step 201, when the first network device is a serving satellite and the second network device is a neighboring satellite, the serving satellite obtains a first parameter. The first parameter is used by user equipment 100 in the overlapping coverage area of ​​the two satellites to determine the measurement start time of the SSB of the neighboring satellite. The first parameter is determined by the serving satellite based on first configuration information of the neighboring satellite. The first configuration information is used to indicate the synchronization signal block SSB index of the neighboring satellite in at least one area, and the at least one area includes the coverage area of ​​the second network device. The first configuration information includes the wave position number of the at least one area and the mapping relationship between the wave position number and the SSB index of the second network device.

[0085] In one possible implementation, the first parameter includes a physical cell identifier (PCI) and an offset time, wherein the physical cell identifier PCI is an identifier for identifying different physical cells in an LTE or 5G network, and the offset time is used to determine the measurement start time of the SSB to be measured of the second network device.

[0086] It's important to note that a beam position refers to the location and range of a satellite beam on the ground. It's the smallest unit of coverage for ground-based beams in satellite communications. A beam position corresponds to a specific coverage area on the ground. The size of the beam position is related to the beamwidth used. For broadcast beams, the size of a beam position can be the same as the coverage area of ​​an SSB beam on the ground.

[0087] The beam position number identifies each beam position, while the SSB index indicates the synchronization signal block number. A physical cell is the basic unit for providing communication services within a specific area. A physical cell may contain multiple beams in different directions, meaning it can cover multiple beam positions. As the satellite moves, the same satellite physical cell will cover beam positions with different numbers at different times.

[0088] Please refer to Figure 2b, which is a schematic diagram of the relationship between a wave position number and an SSB index provided in an embodiment of the present application. In the example shown in Figure 2b, the ground operation and control center can divide the overall ground range covered by the satellite into several areas of fixed size, each area is called a wave position, and all wave positions are assigned non-repeating numbers. The size of each wave position can be set to the same as the SSB beam coverage size to facilitate periodic scanning of the satellite. The specific position and number of each wave position can be preset in the satellite and user equipment chip, or can be periodically issued by the operation and control center and the core network.

[0089] In the example shown in Figure 2b, over a period of time, a satellite covers the same number of ground beam positions as it has SSB beams. Therefore, there is a one-to-one mapping between SSB indices and ground beam numbers. This mapping changes as the satellite moves. The satellite's coverage area over a period of time includes the satellite's SSB index arrangement. The SSB index arrangement within the satellite's coverage area is also called the satellite's SSB pattern.

[0090] In one possible implementation, the first configuration information includes a wavenumber for at least one area, and a mapping relationship between the wavenumber and the SSB index of the second network device, wherein the at least one area also includes an overlapping coverage area between the first and second network devices. That is, the second network device can determine the overlapping coverage area in advance and send the first network device the wavenumber for the overlapping coverage area, and the mapping relationship between the wavenumber and the SSB index of the second network device.

[0091] In one possible implementation, the beam position number may also be the beam center position coordinates. Subsequently, the beam center position coordinates and the beam coverage range may determine the range of the beam position. In this case, the first configuration information includes the beam center position coordinates of at least one area, and a mapping relationship between the beam center position coordinates and the SSB index of the second network device.

[0092] Please refer to Figure 2c, which is a schematic diagram of satellite overlapping coverage areas according to an embodiment of the present application. In the example shown in Figure 2c, the first network device is a serving satellite, and the second network device is a neighboring satellite. There is an overlapping coverage area between the serving satellite and the neighboring satellite. When a user device is in the overlapping coverage area, the user device needs to measure the SSB index of the neighboring satellite.

[0093] In the embodiment of the present application, the first network device can obtain the first parameter in a variety of ways, including: the first network device determines the first parameter based on the first configuration information sent by the second network device, and the first network device receives the first parameter sent by the second network device. The following describes the above two ways for the first network device to obtain the first parameter:

[0094] In a first method of obtaining the first parameter, the first network device receives first configuration information sent by the second network device, and the first network device determines the first parameter based on the first configuration information. Specifically, the first network device determines an overlapping coverage area based on the coverage area of ​​the second network device and the coverage area of ​​the first network device, and determines a wavenumber corresponding to the overlapping coverage area and an SSB index corresponding to the wavenumber.

[0095] When the user equipment 100 is in the overlapping coverage area, the first network device determines the wave position number corresponding to the location of the user equipment 100, and determines the SSB index of the second network device corresponding to the wave position number, that is, the SSB index of the second network device corresponding to the user equipment 100.

[0096] Afterwards, the first network device determines the SSB index of the second network device corresponding to the user device 100 and one or more SSB indexes adjacent to the SSB index as the SSB to be measured of the second network device. The first network device calculates the offset time based on the SSB to be measured of the second network device. There are two ways to calculate the offset time, which are introduced below:

[0097] In the first calculation method, the calculation of the bias time is based on the SSB of the first network device corresponding to the user device 100. At this time, the bias time is defined as the time difference between the SSB to be measured of the second network device and the SSB of the first network device corresponding to the user device 100. The bias time is called the first bias time.

[0098] In the second calculation method, the calculation of the bias time is based on the start time of the measurement cycle of the user device 100. At this time, the bias time is defined as the time difference between the SSB to be measured of the second network device and the start time of the measurement cycle of the user device 100. The bias time is called the second bias time.

[0099] Please refer to Figure 3a, which is a schematic diagram of a process for a first network device to obtain a first parameter according to an embodiment of the present application. In the example shown in Figure 3a, the first network device is a serving satellite, and the second network device is an adjacent satellite. In steps 301 and 302, in which the serving satellite obtains the first parameter, the serving satellite receives first configuration information sent by the adjacent satellite. The first configuration information includes the waveband number of the adjacent satellite's coverage area and the SSB index of the adjacent satellite corresponding to the waveband number. The serving satellite calculates the first parameter based on the first configuration information. The first parameter includes an offset time.

[0100] Please refer to Figure 3b, which is a schematic diagram of an SSB pattern for a serving satellite and an adjacent satellite in an overlapping coverage area, provided by an embodiment of the present application. In the example shown in Figure 3b, the SSB indexes of the serving satellite in the overlapping area include SSB#0, SSB#16, ..., SSB#240, and the SSB indexes of the adjacent satellites in the overlapping area include SSB#255, SSB#239, ..., SSB#15. Among them, SSB#0 of the serving satellite overlaps with SSB#255 of the adjacent satellite, SSB#16 of the serving satellite overlaps with SSB#239 of the adjacent satellite, and SSB#240 of the serving satellite overlaps with SSB#15 of the adjacent satellite.

[0101] In the example shown in FIG3b , the first configuration information includes the wave position number of the adjacent satellite coverage area and the SSB index of the adjacent satellite corresponding to the wave position number, wherein the mapping relationship between the wave position number and the SSB index of the adjacent satellite is shown in Table 1.

[0102] Table 1

[0103] In the example shown in Figure 3b, during the process of calculating the first parameter based on the first configuration information, the serving satellite can determine the overlapping coverage area and the waveband number of the overlapping coverage area based on the coverage range of the adjacent satellite SSB and the coverage range of the serving satellite SSB. When a user device is in the overlapping coverage area and needs to measure the SSB of the adjacent satellite, the serving satellite first determines the waveband number corresponding to the user device based on the SSB index of the serving satellite corresponding to the current user device, and then determines the SSB index of the adjacent satellite based on the waveband number. For example, the serving satellite SSB index corresponding to the user device is SSB#16, and the waveband number corresponding to the serving satellite SSB index SSB#16 is A2. The SSB index of the adjacent satellite corresponding to waveband number A2 is SSB#239, and SSB#239 is the SSB to be measured of the adjacent satellite.

[0104] In the example shown in Figure 3b, taking into account the movement of adjacent satellites and the user device, as well as the influence of the Earth's rotation, the user device needs to measure SSB #239 and its surrounding SSBs after entering the coverage area of ​​the adjacent satellite. As can be seen from the SSB pattern of the adjacent satellite, the SSB indexes of the adjacent satellites adjacent to SSB #239 include SSB #223, SSB #238, and SSB #255. Therefore, when the user is within the coverage area of ​​SSB #16 of the serving satellite, the SSBs of the adjacent satellites that the user device needs to measure include SSB #{223, 238, 239, 255}.

[0105] Please refer to Figure 3c, which is a schematic diagram of calculating the offset time provided by an embodiment of the present application. In the example shown in Figure 3c, the adjacent satellite sends 256 SSBs per measurement cycle. The 256 SSBs are divided into 32 groups for transmission, with 8 SSBs forming a group. A group lasts 20ms, and the 256 SSBs last a total of 640ms. After the serving satellite determines that the SSB to be measured of the adjacent satellite is SSB#{223, 238, 239, 255}, the serving satellite calculates the offset time based on the SSB to be measured of the adjacent satellite. Taking the SSB#223 to be measured of the adjacent satellite as an example, SSB#223 is the SSB in the 27th group. Therefore, the corresponding sending start time of the group to which SSB#223 to be measured belongs is 540ms. Correspondingly, SSB#238 and SSB#239 are SSBs in the 29th group, and the corresponding sending start time of the group to which SSB#238 and SSB#239 to be measured belong is 580ms. SSB#255 is the SSB in the 31st group. Therefore, the sending start time corresponding to the group where the SSB#223 to be tested is located is 620ms.

[0106] Please refer to Figure 3b. In the example shown in Figure 3b, using the first offset time calculation method described above, the offset time is calculated based on the timing of SSB#16 corresponding to the user equipment, that is, 40 ms after the second group of SSBs is transmitted. The calculated offset time for SSB#223 to be tested is 500 ms. Correspondingly, the offset times for SSB#238 and SSB#239 to be tested are 540 ms, and the offset time for SSB#255 to be tested is 580 ms.

[0107] In the example shown in Figure 3b, using the second offset time calculation method, the offset time is calculated based on the start time of the measurement period, that is, the 0th millisecond from the start of the measurement period. Therefore, the offset time corresponding to the measured SSB#223 is calculated to be 540ms. Correspondingly, the offset time corresponding to the measured SSB#238 and SSB#239 is 580ms. The offset time corresponding to the measured SSB#255 is 620ms.

[0108] Here's the second way to get the first parameter:

[0109] In a second method for obtaining the first parameter, the first network device receives the first parameter sent by the second network device. Specifically, the first network device sends second configuration information to the second network device. The second configuration information includes the waveband number of the area covered by the first network device and a mapping between the waveband number and the SSB index of the first network device. The second network device determines the first parameter based on the first and second configuration information.

[0110] Please refer to Figure 4, which is a schematic diagram of another process for a first network device to obtain a first parameter according to an embodiment of the present application. In the example shown in Figure 4, the first network device is a serving satellite, and the second network device is an adjacent satellite. In steps 401 to 404, in which the serving satellite obtains the first parameter, the serving satellite transmits second configuration information to the adjacent satellite. The second configuration information includes the waveband number of the serving satellite's coverage area and the SSB index of the serving satellite corresponding to the waveband number. The adjacent satellite calculates the first parameter based on the first and second configuration information. The first parameter includes an offset time.

[0111] In the example shown in FIG4 , the calculation process of the first parameter is completed in the adjacent satellite. After the service satellite sends the second configuration information to the adjacent satellite, during the process of the adjacent satellite calculating the first parameter based on the second configuration information, the adjacent satellite can determine the overlapping coverage area and the wave position number of the overlapping coverage area based on the coverage range of the service satellite SSB and the coverage range of the adjacent satellite SSB.

[0112] When a user device is in an overlapping coverage area and needs to measure the SSB of a neighboring satellite, the serving satellite first determines the SSB index of the serving satellite corresponding to the user device based on the area where the user device is located, as well as the waveband number corresponding to the SSB index. The neighboring satellite then determines the SSB index of the neighboring satellite corresponding to the user device based on the waveband number. Furthermore, based on the SSB index of the neighboring satellite corresponding to the user device, the neighboring satellite determines multiple SSBs adjacent to the SSB index as the SSBs to be measured by the neighboring satellite.

[0113] In the example shown in FIG4 , after the neighboring satellite determines the SSB to be measured, it calculates the offset time based on the SSB to be measured of the neighboring satellite. The neighboring satellite calculates the offset time based on each SSB to be measured. The manner in which the neighboring satellite calculates the offset time based on the SSB to be measured is consistent with the manner in which the serving satellite calculates the offset time based on the SSB to be measured in the embodiment shown in FIG3 b above, and the details are not repeated here.

[0114] In a possible implementation, when the first configuration information changes, the first network device updates the first parameter based on the changed first configuration information, and sends the updated first parameter to the user equipment.

[0115] Please continue to refer to Figure 3a. In steps 303 to 304 of the example shown in Figure 3a, when the first configuration information of the adjacent satellite changes, the adjacent satellite sends the changed first configuration information to the serving satellite. The serving satellite updates the first parameter based on the changed first configuration information and sends the updated first parameter to the user equipment.

[0116] In one possible implementation, when the second configuration information changes, the first network device sends the changed second configuration information to the second network device, the second network device updates the first parameter based on the changed second configuration information, and sends the updated first parameter to the first network device. After receiving the updated first parameter, the first network device sends the updated first parameter to the user device.

[0117] Continuing with FIG. 4 , in steps 405 to 408 of the example shown in FIG. 4 , when the second configuration information of the serving satellite changes, the serving satellite transmits the changed second configuration information to the neighboring satellite. The neighboring satellite updates the first parameter based on the changed second configuration information and transmits the updated first parameter to the serving satellite. After receiving the updated first parameter, the serving satellite transmits the updated first parameter to the user equipment.

[0118] The following specifically describes a method for updating configuration information in an embodiment of the present application. Since the coverage area of ​​a satellite changes as the satellite moves, that is, the SSB pattern of the satellite changes as the satellite moves, there are two ways in which the SSB pattern changes with the satellite, which are described below respectively:

[0119] In the first SBB pattern change mode, the satellite's SSB pattern is bound to the ground. After the satellite moves, only the edge of the satellite's SSB pattern will change. As long as the user equipment is within the satellite's coverage, the SSB index corresponding to the user equipment will not change. Therefore, the satellite does not need to update the mapping relationship between the wave position number and the SSB index at this time.

[0120] Please refer to Figure 5, which is a schematic diagram of the position relationship between a user device and an SSB pattern provided by an embodiment of the present application. In Figure (a) of the example shown in Figure 5, the SSB pattern of the satellite is bound to the ground. As the satellite moves, the SSB index corresponding to the user device position will not change as long as the user device is within the coverage of the satellite. For example, at time t1, the SSB index corresponding to the user device's position is SSB#17. When the satellite moves, at time t2, the SSB index corresponding to the user device's position is still SSB#17.

[0121] In the second way of changing the SSB pattern, the satellite's SSB index is not bound to the ground. After the satellite moves, the satellite's complete SSB pattern must be refreshed. At this time, the satellite needs to update the SSB index corresponding to the wave position number to obtain the updated configuration information.

[0122] In Figure 5 (b), the satellite's SSB pattern is not tied to the ground. As the satellite moves, the SSB index corresponding to the user device's location changes. For example, at time t1, the SSB index corresponding to the user device's location is SSB#17. When the satellite moves, at time t2, the SSB index corresponding to the user device's location changes to SSB#16. At this time, the satellite needs to update the SSB index corresponding to the wave position number from SSB#17 to SSB#16.

[0123] 202. The first network device sends a first parameter to the user equipment.

[0124] After obtaining the first parameter, the first network device sends the first parameter to the user equipment, where the first parameter includes a physical cell identifier (PCI) and an offset time. The physical cell identifier (PCI) is used to indicate a cell for the user equipment to perform SSB measurement, and each list of physical cell identifiers (PCIs) corresponds to a type of offset time.

[0125] For example, in an example of step 202, after obtaining the first parameter, the serving satellite sends the first parameter to the user equipment. The first parameter "SSB-MTC4" sent by the serving satellite to the user equipment is as follows, where "pci-List" is a list of physical cell identifiers and "offset" is an offset time.

[0126] 203. The user equipment measures the synchronization signal block SSB to be measured of the second network device based on the first parameter.

[0127] After receiving the first parameter sent by the first network device, the user equipment calculates a measurement start time based on the first parameter. The measurement start time is used to indicate the time when the user equipment starts measuring the SSB to be measured of the second network device. The user equipment measures the SSB to be measured of the second network device based on the measurement start time.

[0128] In one possible implementation, the bias time in the first parameter includes a first bias time, which is the bias time calculated in the first calculation method mentioned above. In the process of the user equipment calculating the measurement start time based on the first parameter, the user equipment determines the measurement start time based on the SSB of the first network device and the first bias time. The SSB of the first network device is the SSB corresponding to the area where the user equipment is currently located.

[0129] For example, in an example of step 203, the user equipment receives a first offset time of 500ms, 540ms and 580ms in the first parameter sent by the service satellite. Since the first offset time is based on SSB#16 of the service satellite corresponding to the user equipment (i.e., the 40ms of the measurement period), and since the measurement duration of the user equipment is configured to be 5ms, the user equipment starts from the 40ms of the measurement period and starts measuring the SSB of the adjacent satellite three times with a duration of 5ms at the 500ms, 540ms and 580ms respectively, and can measure SSB#{223, 238, 239, 255}, and only needs to measure 24 SSBs at most.

[0130] In one possible implementation, the bias time includes a second bias time, and the second bias time is the bias time calculated in the second calculation method mentioned above. In the process of the user equipment calculating the measurement start time based on the first parameter, the user equipment determines the measurement start time based on the start time of the measurement period and the second bias time. The measurement period is a measurement period shared by the SSB of the first network device and the SSB to be measured of the second network device.

[0131] In another example of step 203, the user equipment receives the second offset time of the first parameter sent by the service satellite as 540ms, 580ms and 620ms. Since the second offset time is based on the start time of the measurement period, the user equipment starts from the 0th ms of the measurement period and starts the SSB measurement of the adjacent satellite three times with a duration of 5ms at the 540th ms, 580th ms and 620th ms respectively, and can measure SSB#{223, 238, 239, 255}.

[0132] It can be seen from the above embodiments that the user equipment in the embodiments of the present application can determine the measurement start time of the user equipment for measuring the SSB to be measured of the second network device based on the first parameter sent by the first network device, so that the user equipment only needs to start the measurement of the SSB to be measured of the second network device at the measurement start time, thereby reducing the number of SSBs that the user equipment needs to measure and reducing the SSB measurement overhead of the user equipment during the switching process from the first network device to the second network device.

[0133] Based on the above method embodiment, the embodiment of the present application further provides a measurement and processing device. The measurement and processing device provided by the embodiment of the present application is described in detail below.

[0134] Please refer to Figure 6, which is a schematic diagram of the structure of a measurement processing device provided in an embodiment of the present application.

The measurement processing device 600 includes a transceiver unit 601 and a processing unit 602.

[0135] The transceiver unit 601 is configured to receive a first parameter sent by a first network device, the first parameter being determined based on first configuration information, the first configuration information being used to configure a synchronization signal block (SSB) index of a second network device in at least one area, the at least one area including the coverage area of ​​the second network device. The processing unit 602 is configured to calculate a measurement start time based on the first parameter, the measurement start time being used to indicate the time at which the user equipment starts measuring the SSB to be measured of the second network device. The processing unit 602 is further configured to measure the SSB to be measured of the second network device based on the measurement start time.

[0136] In one possible implementation, the first parameter includes a physical cell identifier PCI and an offset time, and the first configuration information includes: a wave position number of at least one area, a mapping relationship between the wave position number and the SSB index of the second network device, and at least one area also includes an overlapping coverage area of ​​the first network device and the second network device.

[0137] In one possible implementation, the bias time includes a first bias time, and the processing unit 602 is specifically used to determine the measurement start time based on the SSB of the first network device and the first bias time, where the SSB of the first network device is the SSB corresponding to the area where the user device is currently located.

[0138] In one possible implementation, the bias time includes a second bias time, and the processing unit 602 is specifically used to determine the measurement start time based on the start time of the measurement period and the second bias time, where the measurement period is a measurement period shared by the SSB of the first network device and the SSB to be measured of the second network device.

[0140] The acquisition unit 701 is configured to acquire a first parameter, where the first parameter is determined based on first configuration information, where the first configuration information is used to configure a synchronization signal block (SSB) index of the second network device in at least one area, where the at least one area includes a coverage area of ​​the second network device. The transceiver unit 702 is configured to send the first parameter to the user equipment, where the first parameter is used to determine a measurement start time for measuring the synchronization signal block (SSB) to be measured of the second network device.

[0141] In one possible implementation, the first parameter includes a physical cell identifier PCI and an offset time, and the first configuration information includes: the wave position number of at least one area, a mapping relationship between the wave position number and the SSB index of the second network device, and at least one area also includes an overlapping coverage area of ​​the first network device and the second network device.

[0142] In a possible implementation, the acquiring unit 701 is specifically configured to receive first configuration information sent by the second network device, and determine the first parameter according to the first configuration information.

[0143] In a possible implementation, the acquiring unit 701 is specifically configured to receive a first parameter sent by the second network device.

[0144] In one possible implementation, the transceiver unit 702 is also used to send second configuration information to the second network device, the second configuration information is used to determine the first parameter, and the second configuration information includes a mapping relationship between the wave position number of the area covered by the first network device, the wave position number of the area covered by the first network device, and the SSB index of the first network device.

[0145] In a possible implementation, the processing unit 703 is further configured to update the first parameter based on the first configuration information when the first configuration information changes, and the transceiver unit 702 is further configured to send the updated first parameter to the user equipment.
