Description

Technical Field

[0001] 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

[0002] A non-terrestrial network (NTN) refers to a network that uses radio frequency resources on platforms such as satellite platforms, unmanned aerial vehicle platforms, or high-altitude communication platforms for communication services.

[0003] In the current non-terrestrial communication network, when a user equipment switches from a serving satellite to an adjacent satellite or performs cell reselection, the user equipment can measure the synchronization signal block (SSB) of the adjacent satellite. During the process of measuring the SSB of the adjacent satellite, when the user equipment is in the overlapping coverage area of the serving satellite and the adjacent satellite, the user equipment also needs to measure all the SSBs of the complete cycle of the adjacent satellite once to determine the optimal SSB. However, due to the large coverage area of the adjacent satellite and the large number of SSB beams in the complete cycle of the adjacent satellite, the measurement overhead of the user equipment is large. Summary of the Invention

[0004] The embodiments of the present application provide a measurement processing method. The user equipment can determine the measurement start time for measuring the synchronization signal block (SSB) of the adjacent satellite based on the first parameter sent by the serving satellite, thereby reducing the measurement overhead of the user equipment. The embodiments of the present application also provide a measurement processing apparatus, an electronic device, a computer-readable storage medium, and a computer program product corresponding to the measurement processing method.

[0005] In a first aspect, the embodiments of the present application provide a measurement processing method. This method can be executed by a user equipment, or by a component of the user equipment, such as a processor, a chip, or a chip system of the user equipment, or can also be implemented by a logic module or software that can implement all or part of the functions of the user equipment. The method provided in the first aspect includes: The user equipment receives a first parameter sent by a first network device. The first network device is, for example, a serving satellite. The first parameter includes a measurement timing configuration (SMTC) parameter based on the synchronization signal block. The first parameter is determined based on first configuration information. The first configuration information is used to configure the SSB index of the synchronization signal block of a second network device in at least one area. The second network device is, for example, an adjacent satellite. The at least one area includes the coverage area of the second network device. The user equipment calculates the 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. When the user equipment switches from the first network device to the second network device, the user equipment measures the SSB to be measured of the second network device based on the measurement start time.

[0006] In an embodiment of the present application, the user equipment can determine the measurement start time for measuring the to-be-measured SSB 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 to-be-measured SSB of the second network device at the determined measurement start time, reducing the number of to-be-measured SSBs of the second network device that the user equipment needs to measure and reducing the measurement overhead of the SSB during the handover process of the user equipment from the first network device to the second network device.

[0007] In a possible implementation manner, the first parameter includes a physical cell identifier (PCI) and a bias time, and the first configuration information includes: the wave position numbers of at least one area, the mapping relationship between the wave position numbers and the SSB index of the second network device, and the at least one area further includes the overlapping coverage area of the first network device and the second network device.

[0008] In an embodiment of the present application, the first parameter received by the user equipment includes a bias time, and the user equipment can calculate the measurement start time based on the bias time in the first parameter, thereby improving the feasibility of the user equipment to determine the measurement start time and further reducing the measurement overhead of the user equipment.

[0009] In a possible implementation manner, the bias time includes a first bias time. During 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, and the SSB of the first network device is the SSB corresponding to the area where the user equipment is currently located.

[0010] In an embodiment of the present application, the user equipment can calculate the measurement start time based on the first bias time with the SSB corresponding to the area where the user equipment is currently located as a reference, thereby improving the feasibility of the user equipment to determine the measurement start time and reducing the measurement overhead of the user equipment for the to-be-measured SSB of the second network device.

[0011] In a possible implementation manner, the bias time includes a second bias time. During 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, and the measurement period is the measurement period shared by the SSB of the first network device and the to-be-measured SSB of the second network device.

[0012] In an embodiment of the present application, the user equipment can calculate the measurement start time based on the second bias time with the start time of the measurement period as a reference, thereby improving the feasibility of the user equipment to determine the measurement start time and reducing the measurement overhead of the user equipment for the to-be-measured SSB of the second network device.

[0013] Second aspect, an embodiment of the present application provides a measurement processing method. This method can be executed by a network device, or by components of the network device, such as a processor, a chip, or a chip system of the network device, or can also be implemented by a logic module or software that can implement all or part of the functions of the network device. The method provided in the second aspect includes: a first network device obtains a first parameter. The first network device is, for example, a serving 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 a second network device in at least one area. The second network device is, for example, an adjacent satellite. The at least one area includes the coverage area of the second network device. The first network device sends the first parameter to a user equipment. The first parameter is used to determine the measurement start time for measuring the to-be-measured SSB of the second network device.

[0014] In an 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 equipment, so that the user equipment calculates the measurement start time based on the first parameter and only needs to start measuring the to-be-measured SSB of the second network device at the measurement start time, reducing the number of to-be-measured SSBs of the second network device that the user equipment needs to measure and reducing the measurement overhead of the SSB during the handover process of the user from the first network device to the second network device.

[0015] In a possible implementation manner, the first parameter includes a physical cell identifier (PCI) and an offset time. The first configuration information includes: the beam number of at least one area, the mapping relationship between the beam number and the SSB index of the second network device. The at least one area further includes the overlapping coverage area of the first network device and the second network device.

[0016] In an embodiment of the present application, the first configuration information of the adjacent satellite can also be the beam number of the overlapping coverage area of the first network device and the second network device, and the mapping relationship between the beam 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 to obtain the first parameter based on the first configuration information.

[0017] In a possible implementation manner, during the process of the first network device obtaining 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 according to the first configuration information. Specifically, the first network device determines the wave position number corresponding to the location area of the user equipment, and determines the SSB index of the second network device corresponding to the location area of the user based on the wave position number. The first network device determines the SSBs to be measured as the SSB index and the SSB indexes adjacent to the SSB index. The first network device determines the first parameter according to the SSB index of the first network device corresponding to the user equipment and the SSB indexes to be measured of the second network device.

[0018] 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, which improves 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 to interact once to calculate the first parameter, thereby improving the interaction efficiency between the first network device and the second network device.

[0019] In a possible implementation manner, during the process of the first network device obtaining 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.

[0020] 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.

[0021] In a possible implementation manner, before the first network device receives the first parameter sent by the second network device, the first network device sends the 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 the wave position number of the area covered by the first network device and the mapping relationship between the wave position number of the area covered by the first network device and the SSB index of the first network device.

[0022] 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.

[0023] In a possible implementation manner, 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.

[0024] 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.

[0025] In a possible implementation manner, when the second configuration information changes, the first network device sends the changed second configuration information to the second network device, and 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.

[0026] In the 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 measurement start time is used to indicate the time when the user equipment starts to measure the SSB to be measured of the second network device.

[0028] In a possible implementation manner, the first parameter includes a physical cell identifier (PCI) and an offset time. The first configuration information includes: the wave position numbers of at least one area, the mapping relationship between the wave position numbers and the SSB index of the second network device. The at least one area further includes the overlapping coverage area of the first network device and the second network device.

[0029] In a possible implementation manner, the offset time includes a first offset time. The processing unit is specifically configured to determine the measurement start time based on the SSB of the first network device and the first offset time.

[0056] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" aims to present relevant concepts in a specific manner.

[0057] 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.

[0058] A Synchronization Signal Block (SSB) refers to a signal with a specific structure in a certain frequency domain, which is used for a user equipment to synchronize and locate a base station at the physical layer. Each base station has unique identification information in the SSB. The user equipment can detect and identify nearby base stations by decoding the identification information of the SSB, and use the SSB for time synchronization and selecting a suitable cell for connection.

[0059] Synchronization Signal Block-based Measurement Timing Configuration (SMTC) is a configuration method for measurement and timing using synchronization signal blocks. By reasonably configuring the SMTC parameters, the user equipment can effectively measure and time the SSB signals of surrounding cells, so that the user equipment can select a suitable access cell.

[0060] To make the technical solutions of this application clearer and easier to understand, the system architecture of this application will be introduced below with reference to the accompanying drawings.

[0061] Please refer to Figure 1a , Figure 1a which is a schematic diagram of the system architecture of a measurement processing system provided by an embodiment of this application. In Figure 1a the example shown, the measurement processing system 10 is a non-terrestrial communication network system. The measurement processing system 10 includes a user equipment 100, a network equipment 200, and a core network 300. The specific functions of each part of the measurement processing system 10 will be introduced below.

[0062] The user equipment 100 refers to the mobile communication device used by the end user, also known as the terminal device. The user equipment 100 has a wireless transceiver function and is used to communicate with the network equipment 200. The user equipment 100 can be a mobile phone, a tablet computer, a computing device with a wireless transceiver function, a virtual reality (VR) device, an augmented reality (AR) device, a vehicle-mounted device, etc. The user equipment 100 can also be a wireless terminal in industrial control, a wireless terminal in remote medical treatment, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc.

[0063] In the embodiments of this application, the deployment method of the user equipment 100 is not limited either. The user equipment 100 can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted, etc., or can be deployed on the water surface, such as the terminal device on a ship, or can be deployed in the air, such as the terminal device in a drone and the terminal device in a balloon.

[0064] The network device 200 can be a device with wireless transceiver functions. The network device 200 is used to provide wireless coverage to the user equipment 100 and connect the user equipment 100 to the core network 203. The network device 200 can be a base station in a non-terrestrial network. For example, it can be an evolved base station in LTE carried on a satellite, a base station or a transceiver point in 5G NR, and base stations evolved by 3GPP later, including macro base stations, micro base stations, pico base stations, small stations, or relay stations, etc. The network device 200 can also be a wireless access node, a wireless relay node, or a wireless backhaul node in a WiFi system, etc.

[0065] In the embodiments of this application, the network device 200 includes a first network device and a second network device. Among them, the first network device refers to the network device that has established a connection with the user equipment 100, and the second network device refers to the network device that the user equipment needs to perform synchronization signal block measurement when switching from the first network device. When the network device 200 is a satellite base station, the first network device is the serving satellite, and the second network device is the adjacent satellite. Among them, the serving satellite is the satellite that is currently providing services to the user equipment 100, and is also called the home satellite. The adjacent satellite refers to the satellite adjacent to the serving satellite, and is also called the neighbor satellite.

[0066] The satellite in the embodiments of this application can be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, or a geostationary earth orbit (GEO) satellite, and is not specifically limited.

[0067] It can be understood that in addition to being a satellite base station, the network device 200 can also be a balloon station, an unmanned aerial vehicle (UAV) platform, or a high altitude platform station (HAPS), etc., and is not specifically limited.

[0068] The core network 300 is used to be responsible for processing and managing the core functions and services in the mobile communication system, including completing functions such as registration, connection, and session management. The core network 300 includes modules such as a network exposure function (NEF) module, a policy and charging function (PCF) module, a session management function (SMF) module, and a user plane function (UPF) module.

[0069] Among them, the Network Exposure Function (NEF) is used to expose the services and capabilities of 3GPP network functions to the Application Function (AF), and at the same time, it also enables the AF to provide information to 3GPP network functions. The Policy and Charging Function (PCF) is used for policy management of charging policies and Quality of Service (QoS) policies. The Session Management Function (SMF) is used to complete session management functions such as IP address allocation for user equipment, UPF selection, charging, and QoS policy control. The User Plane Function (UPF) is used for specific data forwarding on the user plane and generating call detail records based on traffic conditions.

[0070] Please refer to Figure 1b , Figure 1b which is a schematic diagram of the application scenario of a measurement processing method provided by an embodiment of this application. In Figure 1b the example shown, the application scenario of the measurement processing system 10 includes a transparent forwarding scenario and a regeneration mode scenario. Among them, in the transparent forwarding scenario, the network device 200 plays the role of frequency conversion and forwarding, that is, the network device 200 amplifies and forwards the received signal without any processing or decoding of the signal. For example, in Figure 1b the example transparent forwarding scenario shown in (a), the satellite receives the radio frequency signal of the user equipment from the ground station and directly forwards the radio frequency signal through the satellite to the ground receiving station without any processing or operation on the signal. Among them, the ground receiving station includes a 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 transmit radio frequency signals based on multiple radio protocols, such as transmitting radio frequency signals based on Non-3GPP radio protocols or NR radio protocols, which is not specifically limited.

[0071] In the regeneration mode scenario, after receiving the signal, the network device 200 decodes, processes, and re-encodes the signal, and then transmits the signal. At this time, the network device 200 includes a gNB device or a digital processing unit (DU). For example, in Figure 1bIn the example regeneration mode scenario shown in Fig. (b), the satellite receives the radio frequency signal from the ground user equipment, then demodulates, denoises, and corrects the error code of the radio frequency signal, and regenerates a compensation signal. Then, the compensation signal is retransmitted by the satellite to the ground receiving station through the F1 interface. Among them, the ground receiving station includes a gNB base station or a centralized unit (CU). Among them, the F1 interface refers to a protocol interface based on the Internet Protocol (IP). The F1 interface usually uses the physical layer protocol of the satellite link as the transmission medium, such as satellite signals in the Ka band or Ku band.

[0072] In Figure 1b Figs. (a) and Figure 1b In the examples shown in Fig. (b), the NG interface is the information interaction interface between the ground receiving station and the core network. The NG interface includes the N2 interface and the N3 interface. Among them, 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.

[0073] Based on Figure 1a the measurement processing system 10 shown, the present application also provides a measurement processing method. The measurement processing method provided by the embodiments of the present application will be introduced below in conjunction with the embodiments.

[0074] Please refer to Figure 2a , Figure 2a which is a schematic flowchart of an interaction method for measurement information provided by an embodiment of the present application. In Figure 2a the example shown, the method includes the following steps:

[0075] 201. The first network device obtains a first parameter, which is determined based on first configuration information for configuring the synchronization signal block (SSB) index of the second network device in at least one area.

[0076] The first network device obtains a first parameter, which includes a measurement timing configuration for synchronization signal block (SMTC4) parameter for determining the starting measurement time of the user equipment for the synchronization signal block (SSB). The first parameter is determined based on first configuration information, where the first configuration information is used to indicate the configuration of the 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.

[0077] It should be noted that the SMTC4 parameter is a measurement timing configuration parameter defined in the New Radio (NR) protocol. There are 4 measurement timing configuration parameters defined in the NR protocol, including the SMTC1 parameter, the SMTC2 parameter, the SMTC3 parameter, and the SMTC4 parameter. Among them, the SMTC1 parameter is the main measurement timing configuration parameter, including the period, offset time, and duration. The period is used to determine the frequency at which the user equipment measures the Synchronization Signal Block (SSB), the offset time is used to determine the starting time position at which the user equipment measures the SSB, and the duration is used to determine the time window length for the user equipment to measure the SSB.

[0078] The SMTC2 parameter is an auxiliary measurement timing configuration parameter. The SMTC2 parameter mainly includes the cell list (pci-list) and the period. Compared with the SMTC1 parameter, the SMTC2 parameter is a measurement timing configuration parameter for SSB measurement for specific cells, and the period in the SMTC2 parameter is generally shorter than the period in the SMTC1 parameter, and it reuses the same offset time and duration as the SMTC1 parameter.

[0079] The SMTC3 parameter is a measurement timing configuration parameter applied in the Integrated Access and Backhaul (IAB) scenario. The SMTC3 parameter configures the period, offset time, duration, and cell list separately, and the SMTC3 parameter specifies the SSB index to be measured.

[0080] The SMTC4 parameter is a measurement timing configuration parameter applied in the Non-Terrestrial Network (NTN) scenario. In the NTN scenario, since the time delays from different network devices (such as satellites) to the user equipment are different, if the first network device and the second network device adopt the same offset time configuration, it may be impossible to measure the SSB of the second network device within the configured duration, resulting in a measurement failure.

[0081] Therefore, the SMTC4 parameter mainly includes the list of Physical Cell Identifiers (PCI) and the offset time. Among them, the list of Physical Cell Identifiers (PCI) is used to determine the cells for which the user equipment performs SSB measurement, and each list of Physical Cell Identifiers (PCI) corresponds to a type of offset time. The SMTC4 parameter allows configuring 3 lists of Physical Cell Identifiers (PCI).

[0082] Compared with the SMTC1 parameters, the network device side can calculate the SSB arrival time delays of different network devices (such as satellites) according to the positions of each network device (such as satellites) 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. For the period and duration, the SMTC4 parameters are reused with the SMTC1 parameters.

[0083] In an example of step 201, when the first network device is a serving satellite and the second network device is an adjacent satellite. The serving satellite obtains a first parameter, which is used for the user equipment 100 in the overlapping coverage area of the two satellites to determine the measurement start time for the SSB of the adjacent satellite. The first parameter is determined by the serving satellite based on the first configuration information of the adjacent satellite, where the first configuration information is used to indicate the synchronization signal block SSB index of the adjacent 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.

[0084] In a possible implementation, the first parameter includes a physical cell identifier (physical cell ID, PCI) and an offset time. Among them, the physical cell identifier PCI is an identifier for identifying different physical cells in the LTE or 5G network, and the offset time is used to determine the measurement start time for measuring the SSB to be measured of the second network device.

[0085] It should be noted that a wave position refers to the position and range of a satellite beam on the ground, and is a minimum unit for dividing the beam coverage range on the ground in satellite communication. A wave position corresponds to a certain coverage range on the ground, and the size of the wave position is related to the beam width of the used beam. For a broadcast beam, the size of a wave position can be the same as the coverage range of an SSB beam on the ground.

[0086] The wave position number represents the identification of each wave position, and the SSB index represents the number of the synchronization signal block. A physical cell is a basic unit that provides communication services within a specific area. A physical cell may contain multiple beams in different directions, that is, it can cover multiple wave positions. As the satellite moves, the same satellite physical cell will cover different numbered wave positions at different times.

[0087] Please refer to Figure 2b , Figure 2b which is a schematic diagram of the relationship between the wave position number and the SSB index provided for the embodiments of this application. In Figure 2bIn the example shown, the ground control center can divide the overall ground area covered by the satellite into several regions with a fixed size. Each region is called a wave position, and a unique number is assigned to all wave positions. The size of each wave position can be set to be the same as the coverage size of the SSB beam, which is convenient for the satellite to perform periodic scanning. The specific position and number of each wave position can be preset in the satellite and the user equipment chip, or can be periodically sent by the control center and the core network.

[0088] In Figure 2b the example shown, within a period of time, a satellite will cover the same number of ground wave positions as the number of SSB beams. Therefore, there is a one-to-one mapping relationship between the SSB index and the ground beam number. As the satellite moves, this mapping relationship will also change. During a certain period, the coverage area of the satellite includes the arrangement of the SSB indexes of the satellite. The arrangement of the SSB indexes in the coverage area of the satellite is also called the SSB pattern of the satellite.

[0089] In a possible implementation manner, the first configuration information includes the wave position numbers of at least one region and the mapping relationship between the wave position numbers and the SSB indexes of the second network device, where at least one region further includes the overlapping coverage region of the first network device and the second network device. That is, the second network device can determine the overlapping coverage region in advance and send the mapping relationship between the wave position numbers of the overlapping coverage region, the wave position numbers, and the SSB indexes of the second network device to the first network device.

[0090] In a possible implementation manner, the wave position number can also be the position coordinates of the beam center point. Subsequently, the beam center point coordinates and the beam coverage range can determine the range of the wave position. At this time, the first configuration information includes the position coordinates of the wave position center point of at least one region and the mapping relationship between the position coordinates of the wave position center point and the SSB indexes of the second network device.

[0091] Please refer to Figure 2c , Figure 2c which is a schematic diagram of the overlapping coverage region of the satellite provided by the embodiment of the present application. In Figure 2c the example shown, the first network device is a serving satellite, and the second network device is an adjacent satellite. There is an overlapping coverage region between the serving satellite and the adjacent satellite. When the user equipment is in the overlapping coverage region, the user equipment needs to measure the SSB indexes of the adjacent satellite.

[0092] In the embodiment of the present application, the first network device can obtain the first parameter in multiple 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 introduces the above two ways for the first network device to obtain the first parameter respectively:

[0093] In the first method of obtaining 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 according to the first configuration information. Specifically, the first network device determines the overlapping coverage area based on the coverage area of the second network device and the coverage area of the first network device, determines the wave position number corresponding to the overlapping coverage area, and the SSB index corresponding to the wave position number.

[0094] 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.

[0095] After that, the first network device determines the SSB index of the second network device corresponding to the user equipment 100 and one or more SSB indexes adjacent to the SSB index as the SSBs to be measured of the second network device. The first network device calculates the offset time based on the SSBs to be measured of the second network device. There are two ways to calculate the offset time, which are introduced separately below:

[0096] In the first calculation method, the calculation of the offset time is based on the SSB of the first network device corresponding to the user equipment 100. At this time, the offset 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 equipment 100, and this offset time is called the first offset time.

[0097] In the second calculation method, the calculation of the offset time is based on the start time of the measurement period of the user equipment 100. At this time, the offset 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 period of the user equipment 100, and this offset time is called the second offset time.

[0098] Please refer to Figure 3a , Figure 3a which is a schematic flowchart of a process for a first network device to obtain a first parameter provided by an embodiment of this application. In the example shown in Figure 3a , the first network device takes the serving satellite as an example, and the second network device takes the adjacent satellite as an example. In steps 301 to 302 of the serving satellite obtaining the first parameter, the serving satellite receives the first configuration information sent by the adjacent satellite. The first configuration information includes the wave position number of the coverage area of the adjacent satellite and the SSB index of the adjacent satellite corresponding to the wave position number. The serving satellite calculates the first parameter according to the first configuration information, and the first parameter includes the offset time.

[0099] Please refer to Figure 3b , Figure 3bThis is a schematic diagram of the SSB pattern of a serving satellite and adjacent satellites in the overlapping coverage area provided by an embodiment of the present application. In Figure 3b In the example shown, 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.

[0100] In Figure 3b In the example shown, the first configuration information includes the wave position numbers of the coverage areas of the adjacent satellites and the SSB indexes of the adjacent satellites corresponding to the wave position numbers. The mapping relationship between the wave position numbers and the SSB indexes of the adjacent satellites is shown in Table 1, for example.

[0101] Table 1

[0102] Wave position number SSB index of adjacent satellites A1 255 A2 239 A3 223 … …

[0103] In Figure 3b In the example shown, when the serving satellite calculates the first parameter according to the first configuration information, the serving satellite can determine the overlapping coverage area and the wave position numbers of the overlapping coverage area based on the coverage range of the SSB of the adjacent satellite and the coverage range of the SSB of the serving satellite. When the user equipment is in the overlapping coverage area and needs to measure the SSB of the adjacent satellite, the serving satellite first determines the wave position number corresponding to the user equipment according to the SSB index of the serving satellite corresponding to the current user equipment, and then determines the SSB index of the adjacent satellite according to the wave position number. For example, the SSB index of the serving satellite corresponding to the user equipment is SSB#16, the wave position number corresponding to the SSB index of the serving satellite SSB#16 is A2, and the SSB index of the adjacent satellite corresponding to the wave position number A2 is SSB#239. This SSB#239 is the SSB to be measured of the adjacent satellite.

[0104] In Figure 3b In the example shown, considering the movement of the adjacent satellite and the user equipment and the influence of the earth's rotation, after the user equipment enters the coverage range of the adjacent satellite, it needs to measure SSB#239 and the SSBs around it. It can be seen from the SSB pattern of the adjacent satellite that 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 range of SSB#16 of the serving satellite, the SSBs of the adjacent satellite that the user equipment needs to measure include SSB#{223, 238, 239, 255}.

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

[0106] Please continue to refer to Figure 3b , in the example shown in Figure 3b , taking the above first calculation method of the offset time as an example, the calculation of the offset time is based on the time of SSB#16 corresponding to the user equipment, that is, based on the 40th ms after the transmission of the 2nd group of SSBs. The calculated offset time corresponding to the SSB#223 to be measured is 500 ms. Correspondingly, the offset times corresponding to the SSB#238 and SSB#239 to be measured are 540 ms, and the offset time corresponding to the SSB#255 to be measured is 580 ms.

[0107] In the example shown in Figure 3b , taking the above second calculation method of the offset time as an example, the calculation of the offset time is based on the start time of the measurement period, that is, based on the 0th ms at the start of the measurement period. Then the calculated offset time corresponding to the SSB#223 to be measured is 540 ms. Correspondingly, the offset times corresponding to the SSB#238 and SSB#239 to be measured are 580 ms. The offset time corresponding to the SSB#255 to be measured is 620 ms.

[0108] The following introduces the second method for obtaining the first parameter:

[0109] In the second method of obtaining the first parameter, the first network device receives the first parameter sent by the second network device. Specifically, the first network device sends the second configuration information to the second network device. The second configuration information includes the wave position numbers in the area covered by the first network device, and the mapping relationship between the wave position numbers and the SSB indexes of the first network device. The second network device determines the first parameter based on the first configuration information and the second configuration information.

[0110] Please refer to Figure 4 , Figure 4 which is another schematic flowchart of the first network device obtaining the first parameter provided for the implementation of this application. In Figure 4 the example shown, the first network device takes the serving satellite as an example, and the second network device takes the adjacent satellite as an example. In steps 401 to 404 of the serving satellite obtaining the first parameter, the serving satellite sends the second configuration information to the adjacent satellite. The second configuration information includes the wave position numbers in the area covered by the serving satellite, and the SSB indexes of the serving satellite corresponding to the wave position numbers. The adjacent satellite calculates the first parameter based on the first configuration information and the second configuration information. The first parameter includes the offset time.

[0111] In Figure 4 the example shown, the calculation process of the first parameter is completed in the adjacent satellite. After the serving satellite sends the second configuration information to the adjacent satellite, during the process of the adjacent satellite calculating the first parameter according to the second configuration information, the adjacent satellite can determine the overlapping coverage area and the wave position numbers in the overlapping coverage area according to the coverage range of the serving satellite's SSB and the coverage range of the adjacent satellite's SSB.

[0112] When the user equipment is in the overlapping coverage area and needs to measure the SSB of the adjacent satellite, the serving satellite first determines the SSB index of the serving satellite corresponding to the user equipment according to the area where the user equipment is located, and the wave position number corresponding to the SSB index. The adjacent satellite determines the SSB index of the adjacent satellite corresponding to the user equipment according to the wave position number. Further, the adjacent satellite determines multiple SSBs adjacent to the SSB index corresponding to the user equipment as the SSBs to be measured of the adjacent satellite based on the SSB index of the adjacent satellite corresponding to the user equipment.

[0113] In Figure 4 the example shown, after the adjacent satellite determines the SSBs to be measured, it calculates the offset time based on the SSBs to be measured of the adjacent satellite. The adjacent satellite calculates the offset time based on each SSB to be measured. The method for the adjacent satellite to calculate the offset time based on the SSBs to be measured is the same as the method for the serving satellite to calculate the offset time based on the SSBs to be measured in the embodiment shown in Figure 3b above, and will not be elaborated 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 Figure 3a In steps 303 to 304 of the example shown, when the first configuration information of an 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 a 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 equipment.

[0117] Please continue to refer to Figure 4 , in Figure 4 In steps 405 to 408 of the example shown, when the second configuration information of the serving satellite changes, the serving satellite sends the changed second configuration information to the adjacent satellite. The adjacent satellite updates the first parameter based on the changed second configuration information and sends the updated first parameter to the serving satellite. After receiving the updated first parameter, the serving satellite sends the updated first parameter to the user equipment.

[0118] The following specifically introduces the update method of the configuration information in the embodiments of the present application. Since the coverage area of the satellite changes with the movement of the satellite, that is, the SSB pattern of the satellite changes with the movement of the satellite. There are two ways for the SSB pattern to change with the satellite, which are introduced separately below:

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

[0120] Please refer to Figure 5 , Figure 5 which is a schematic diagram of the positional relationship between the user equipment and the SSB pattern provided by the embodiments of the present application. In Figure 5In Figure (a) of the shown example, the SSB pattern of the satellite is bound to the ground. As the satellite moves, only when the user equipment is within the coverage of the satellite, the SSB index corresponding to the location of the user equipment will not change. For example, at time t1, the SSB index corresponding to the location of the user equipment is SSB#17. When the satellite moves, at time t2, the SSB index corresponding to the location of the user equipment is still SSB#17.

[0121] In the second way of changing the SSB pattern, the SBB index of the satellite is not bound to the ground. After the satellite moves, the complete SSB pattern of the satellite needs to 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 In Figure (b) of the shown example, the SSB pattern of the satellite is not bound to the ground. As the satellite moves, the SSB index corresponding to the location of the user equipment will change. For example, at time t1, the SSB index corresponding to the location of the user equipment is SSB#17. When the satellite moves, at time t2, the SSB index corresponding to the location of the user equipment becomes 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 the first parameter to the user equipment.

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

[0125] For example, in an example of step 202, after the serving satellite obtains the first parameter, it 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. Among them, "pci-List" is the list of physical cell identifiers, and "offset" is the offset time.

[0126] SSB-MTC4::={

[0127] pci-List{adjacent satellite PCI}

[0128] offset-List{sf500, sf540, sf580} (offset time obtained by the first calculation method)

[0129] or offset-List{sf540, sf580, sf620} (offset time obtained by the second calculation method)

[0130] }

[0131] 203. The user equipment measures the to-be-measured synchronization signal block (SSB) of the second network device based on the first parameter.

[0132] After receiving the first parameter sent by the first network device, the user equipment calculates the measurement start time based on the first parameter. The measurement start time is used to indicate the time when the user equipment starts to measure the to-be-measured SSB of the second network device. The user equipment measures the to-be-measured SSB of the second network device based on the measurement start time.

[0133] In a possible implementation manner, the offset time in the first parameter includes a first offset time. The first offset time is the offset time calculated in the first calculation method described above. When the user equipment calculates 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 offset time. The SSB of the first network device is the SSB corresponding to the area where the user equipment is currently located.

[0134] For example, in an example of step 203, the first offset times in the first parameter sent by the serving satellite received by the user equipment are 500 ms, 540 ms, and 580 ms. Since the first offset time is based on the SSB#16 of the serving satellite corresponding to the user equipment (i.e., the 40th ms of the measurement period), and since the measurement duration of the user equipment is configured to be 5 ms, therefore, starting from the 40th ms of the measurement period, the user equipment starts three measurements of the SSBs of adjacent satellites with a duration of 5 ms at the 500th ms, the 540th ms, and the 580th ms respectively, and can measure the SSBs#{223, 238, 239, 255}, and at most only need to measure 24 SSBs.

[0135] In a possible implementation manner, the offset time includes a second offset time. The second offset time is the offset time calculated in the second calculation method described above. When the user equipment calculates 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 offset time. The measurement period is the measurement period shared by the SSB of the first network device and the to-be-measured SSB of the second network device.

[0136] In another example of step 203, the second bias times in the first parameter sent by the serving satellite received by the user equipment are 540 ms, 580 ms, and 620 ms. Since the second bias time is based on the start time of the measurement period, the user equipment starts from the 0 ms of the measurement period and respectively starts three measurements of the SSBs of adjacent satellites with a duration of 5 ms at the 540th ms, the 580th ms, and the 620th ms, and then can measure the SSBs #{223, 238, 239, 255}.

[0137] As can be seen from the above embodiments, in the embodiments 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 measurement start time, reducing the number of SSBs that the user equipment needs to measure and reducing the measurement overhead of the SSB during the handover process of the user equipment from the first network device to the second network device.

[0138] Based on the above method embodiments, the embodiments of the present application further provide a measurement processing device, and the measurement processing device provided by the embodiments of the present application will be specifically introduced below.

[0139] Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of a measurement processing device provided by the embodiments of the present application.

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

[0140] Among them, the transceiver unit 601 is used to receive the first parameter sent by the first network device. The first parameter is determined based on the first configuration information, and the first configuration information is used to configure 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. The processing unit 602 is used to calculate the measurement start time based on the first parameter, and 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 processing unit 602 is also used to measure the SSB to be measured of the second network device based on the measurement start time.

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

[0142] In a possible implementation, the offset time includes a first offset time. Specifically, the processing unit 602 is configured to determine the measurement start time based on the SSB of the first network device and the first offset time, where the SSB of the first network device is the SSB corresponding to the area where the user equipment is currently located.

[0143] In a possible implementation, the offset time includes a second offset time. Specifically, the processing unit 602 is configured to determine the measurement start time based on the start time of the measurement period and the second offset time, where the measurement period is the measurement period shared by the SSB of the first network device and the SSB to be measured of the second network device.

[0144] Please refer to Figure 7 , Figure 7 which is a schematic structural diagram of a measurement processing device provided by an embodiment of the present application.

[0145] Among them, the acquisition unit 701 is configured to acquire a first parameter, where the first parameter is determined based on first configuration information, and the first configuration information is used to configure 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. The transceiver unit 702 is configured to send the first parameter to the user equipment, and the first parameter is used to determine the measurement start time for measuring the SSB to be measured of the second network device.

[0146] In a possible implementation, the first parameter includes a physical cell identifier (PCI) and an offset time, and the first configuration information includes: the wave position numbers of at least one area, the mapping relationship between the wave position numbers and the SSB index of the second network device, and the at least one area further includes the overlapping coverage area of the first network device and the second network device.

[0147] In a possible implementation, the acquisition unit 701 is specifically configured to receive the first configuration information sent by the second network device and determine the first parameter according to the first configuration information.

[0148] In a possible implementation, the acquisition unit 701 is specifically configured to receive the first parameter sent by the second network device.

[0149] In a possible implementation, the transceiver unit 702 is further configured to send second configuration information to the second network device, where the second configuration information is used to determine the first parameter, and the second configuration information includes the wave position numbers of the area covered by the first network device and the mapping relationship between the wave position numbers of the area covered by the first network device and the SSB index of the first network device.

[0150] 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.
