Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a measurement method, apparatus, terminal, and network-side equipment. Background Technology

[0002] Terrestrial networks typically employ a cellular networking approach. The widespread adoption of cellular networks stems from a mathematical conclusion: when covering a plane with circles of equal radius, the number of circles required is minimized when their centers are located at the centers of the regular hexagons in a hexagonal grid, or in other words, when their centers are located at the grid points of an equilateral triangular grid.

[0003] The widely adopted cellular network is a planar cell, which provides good service performance for traditional ground terminals. However, for special terminals such as aircraft, providing services to aircraft based on terrestrial network technology involves too much complexity, including handover, access, and neighbor cell management. For example, as the aircraft moves, such as during takeoff or landing, it may quickly pass through multiple cells based on the terrestrial network, resulting in frequent handovers and a decline in system performance.

[0004] One possible deployment approach is a combination of multiple networks. For example, the cell providing services could be a terrestrial network, an airborne network (e.g., a drone), or a space-based network (e.g., a satellite). Due to the different flight characteristics of the aircraft and the different channel models and propagation characteristics resulting from the types of service base stations, this combined network service terminal will encounter many problems. For instance, the different types of networks in the combined network, such as terrestrial, airborne, and space-based networks, have different propagation channels and propagation delays, affecting the measurement performance of the terminal.

[0171] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0172] To address the mobility issues caused by aircraft terminals rapidly traversing multiple cells (including vertical and horizontal dimensions, which can be of the same or different types of base stations) within a short period, this invention introduces a three-dimensional cell. A three-dimensional cell refers to a cell formed by one or more base stations, transmitters, antennas, or satellites using smart antenna technology. Multiple three-dimensional cells can form a three-dimensional cell cluster. The introduction of this three-dimensional cell impacts the terminal's mobility performance. This three-dimensional cell can cover multiple network devices within a single network, or it can cover network devices within at least two networks. These networks include: terrestrial networks, airborne networks, and space-based networks (such as satellites).

[0173] It should be noted that a three-dimensional cell can also be called a cell formed by combining multiple existing ordinary cells (or planar cells) or multiple beams. Compared with ordinary cells, the coverage of a three-dimensional cell is larger (e.g., horizontal coverage and vertical coverage). In addition, space-based network equipment or space-based network equipment may be moved. All of the above factors will affect the terminal's measurement, cell reselection or cell handover.

[0174] Considering that terrestrial base stations, space base station equipment, and satellites can jointly form a three-dimensional cell, even if all three send signals synchronously, the different transmission delays may cause the terminal to receive the reference symbol of the same cell at different times. This situation contradicts the periodic transmission of reference symbols (the transmission of a reference symbol at a certain frequency can be considered to have a fixed period, fixed duration, and fixed offset), which may lead to confusion in terminal measurement behavior. Moreover, for terminals located in different locations, the signal strength received from the three network devices will be different, making it impossible to guarantee measurement performance.

[0175] In response to the above problems, such as Figure 1 As shown, embodiments of the present invention provide a measurement method, including at least one of the following:

[0176] Step 101: The terminal receives the first information;

[0177] Step 102: Measure some or all of the reference symbols at the terminal.

[0178] Step 103: The terminal reports some or all of the measurement results.

[0179] As an optional embodiment, step 101 includes:

[0180] The terminal receives first information from the first cell, wherein the first cell includes multiple network devices located at different altitudes and / or longitudes and / or latitudes and / or different geographical locations and / or different speeds.

[0181] As an optional embodiment, the first information includes: measurement-related measurement information. The aforementioned reference symbols can be obtained from the measurement information.

[0182] As an optional embodiment, the measurement information includes at least one of the following:

[0183] Period of the reference symbol;

[0184] Duration of the reference symbol;

[0185] Offset value of the reference symbol;

[0186] The period of the measurement interval;

[0187] The duration of the measurement interval;

[0188] The offset value of the measurement interval;

[0189] The third indication information includes at least one of the following: a pre-configured measurement interval, a network control interval, and a concurrent measurement interval.

[0190] The third indication information is used to indicate the type of measurement interval. A pre-configured measurement interval can also be described as a pre-configured measurement gap (Pre-MG). This type of measurement interval is configured by RRC and activated / deactivated via network indication or by meeting certain criteria. A network-controlled small gap (NCSG) can also be described as a network-controlled small gap, which has a short measurement duration or a small terminal size. A concurrent measurement interval can also be described as a concurrent measurement gap, meaning that multiple measurement intervals can be configured.

[0191] It should be noted that the above reference symbols are measurement reference symbols, including the Synchronization Signal Block (SSB, which can also be described as SMTC), and / or the Channel State Information Reference Signal (CSI-RS), and / or the Positioning Reference Signal (PRS), etc.

[0192] As an optional embodiment, the method further includes:

[0193] The terminal receives second information, which includes the association between measurement information and a first node and / or beam. This second information can be broadcast or transmitted via Radio Resource Control (RRC) (e.g., configured in the MO). The first node is the first node of the first cell. The terminal can determine the measurement information of the first cell based on the association in the first information.

[0194] Network nodes operating at different altitudes and / or longitudes and / or latitudes have different identifiers, and measurement information can be associated with the relevant identifiers. Measurement information can also be associated with beam identifiers. Beams with different identifiers or different identifier groups (i.e., the group has multiple beams, corresponding to multiple beam IDs, and the beams in the group all belong to the same or the same type of network device) come from different network nodes.

[0195] For example, the second information includes: the association between measurement information and the identifier of the first node; for another example, the second information includes: the association between measurement information and the beam identifier; for yet another example, the second information includes: the association between measurement information and the identifier of the first node and the beam identifier.

[0196] As an optional embodiment, the second information includes at least one of the following:

[0197] At least one set of Synchronization Signal / Physical Broadcast Channel Block Measurement Timing Configuration (SMTC) information corresponding to the Synchronization Signal Block (SSB);

[0198] SMTC offset information; Considering that ground base stations, space base station equipment, and satellites can jointly form a three-dimensional cell, even if all three send signals synchronously, due to different transmission delays, the terminal may receive the reference symbol of the same cell at different times. When a cell only sends one or more fixed sets of SMTCs (multiple sets of SMTCs mean that even if at least two sets of SMTCs are sent, but the SMTCs are not mapped one-to-one with network devices), the terminal can be further instructed to receive the time domain offset of a certain type of network device based on the current SMTC configuration; the SMTC offset information includes the SMTC offset information for different network devices. For different network devices (e.g., network devices at different altitudes and / or longitudes and / or latitudes and / or speeds; or different types of network devices, such as ground networks / base stations, drones, airborne base stations (ATG), hot air balloons, satellites, etc.), the SMTC offset information can be different, and the offset information includes at least one of the following: periodic offset, duration offset, and starting position offset.

[0199] CSI-RS offset information includes the offset information of the CSI-RS configuration for different network devices in the same cell. For different network devices (e.g., network devices at different altitudes and / or longitudes and / or latitudes and / or speeds; or different types of network devices, such as terrestrial networks / base stations, drones, airborne base stations (ATG), hot air balloons, satellites, etc.), the CSI-RS configuration can be different, that is, there are different configurations for different devices, which can also be described as different offset information. The offset information includes at least one of the following: periodic offset, duration offset, and start position offset.

[0200] The relationship between SMTC and altitude; this altitude can be the height of the network device relative to sea level or land level, the angle or direction of the network device relative to sea level or land level, or the coverage area of ​​the network device relative to sea level or land level. A cell or a frequency point can transmit multiple sets of SMTCs, and different SMTCs correspond to different altitude thresholds; this altitude includes a specific altitude threshold as well as a certain altitude range. This relationship can also be described as a correspondence.

[0201] The relationship between Channel State Information Reference Signal (CSI-RS) and altitude; this altitude can be the height of the network device relative to the sea level or land level, the angle or direction of the network device relative to the sea level or land level, or the coverage area of ​​the network device relative to the sea level or land level. A single cell or frequency point can transmit multiple sets of CSI-RS, each corresponding to a different altitude threshold; this altitude includes a specific altitude threshold as well as a certain altitude range. This relationship can also be described as a correspondence.

[0202] The relationship between SMTC and beams; beams here include SSB beams, data receive beams (e.g., PDSCH, PDCCH), and data transmit beams (e.g., PUSCH, PUCCH, SRS). Different beams or beam groups correspond to different network devices. The association between SMTC / CSI-RS / location symbols and beams (e.g., establishing an association between SMTC / CSI-RS / location symbols and beam indices) indirectly establishes the association between SMTC / CSI-RS / location symbols and network devices (e.g., establishing an association between SMTC / CSI-RS / location symbols and network device identifiers). Different beams can be distinguished by beam indices.

[0203] The relationship between CSI-RS and beamlines; specifically, this includes the relationship between the CSI-RS measurement window and the beam index; it also includes the relationship between the CSI-RS resource set ID and the beam index; it also includes the relationship between the CSI-RS resource ID and the beam index.

[0204] The relationship between SMTC and network devices; for example, the relationship between SMTC and network device identifiers; network device identifiers can have multiple values ​​to distinguish between ground-based, air-based, and space-based devices. A cell or frequency point can transmit multiple sets of SMTCs, and different SMTCs correspond to different second identifier values, helping the UE distinguish SMTCs from different network devices from the same cell / frequency point;

[0205] The relationship between CSI-RS and network devices; for example, the relationship between CSI-RS and network device identifiers; network device identifiers can have multiple values ​​to distinguish between ground-based, air-based, and space-based devices. A cell or frequency point can transmit multiple sets of CSI-RS, and different CSI-RS correspond to different third identifier values, helping the UE distinguish CSI-RS from different network devices in the same cell / frequency point;

[0206] The offset information of the positioning symbol includes the offset information of the positioning symbol relative to different network devices in the same cell. For different network devices (e.g., network devices at different altitudes and / or longitudes and / or latitudes and / or speeds; or different types of network devices, such as terrestrial networks / base stations, drones, airborne base stations (ATG), hot air balloons, satellites, etc.), the configuration of the positioning information can be different, that is, there are different configurations for different devices, which can also be described as different offset information. The offset information includes at least one of the following: periodic offset, duration offset, and starting position offset.

[0207] The relationship between the positioning symbol and its height; this height includes a specific height threshold as well as a certain height range. This relationship can also be described as a correspondence.

[0208] The association between location symbols and beams; beams here include SSB beams, data reception beams (e.g., PDSCH, PDCCH), and data transmission beams (e.g., PUSCH, PUCCH, SRS). Different beams or beam groups correspond to different network devices. This association is achieved indirectly through the linking of SMTC / CSI-RS / location symbols to beams (e.g., linking SMTC / CSI-RS / location symbols to beam indices), thus linking SMTC / CSI-RS / location symbols to network devices (e.g., linking SMTC / CSI-RS / location symbols to network device identifiers). Different beams can be distinguished by beam indices.

[0209] The relationship between location symbols and network devices; for example, the relationship between location symbols and network device identifiers; network device identifiers can have multiple values ​​to distinguish between ground-based devices, air-based devices, and space-based devices.

[0210] The second information may include multiple sets of SMTC information, each corresponding to different network devices in the first cell. Different SMTCs correspond to terrestrial network devices and / or space network base station devices and / or satellites, respectively. Furthermore, it may indicate which network device(s) a particular SMTC corresponds to.

[0211] Optionally, the first node includes at least one of the following:

[0212] Network units operating at different heights;

[0213] Network units operating at different longitudes;

[0214] Network units operating at different latitudes.

[0215] It should be noted that a network unit can also be described as a network node. Here, a network unit includes at least one of the following: a ground base station, a satellite, a drone, or a hot air balloon.

[0216] As an optional embodiment, the method further includes:

[0217] The terminal receives third information, which indicates at least one of the following:

[0218] The correlation between the measurement information and different heights;

[0219] The correlation between the measurement information and different longitudes;

[0220] The correlation between the measurement information and different latitudes;

[0221] The correlation between the measurement information and different speeds;

[0222] The measurement information is correlated with different time thresholds. These time thresholds include the terminal receiving time meeting a certain threshold, and / or the terminal receiving time difference meeting a certain threshold. Meeting a certain threshold for the terminal receiving time takes into account the different arrival times of reference symbols sent by network units with different longitudes, latitudes, altitudes, and speeds at the terminal; therefore, correlation is needed to distinguish them and assist the terminal in measurement. Meeting a certain threshold for the terminal receiving time difference takes into account the different arrival times of reference symbols sent by network units with different longitudes, latitudes, altitudes, and speeds at the terminal; measurement information where the arrival time difference meets a certain threshold can be measured. Network units with different longitudes, latitudes, altitudes, and speeds can belong to the same cell and be associated with the same PCI.

[0223] The terminal can determine the measurement information of the first cell based on the correlation in the third information.

[0224] In at least one embodiment of the present invention, step 102 includes:

[0225] Reference symbols for matching terminal measurements with the terminal's altitude and / or longitude and / or latitude and / or speed and / or terminal trajectory;

[0226] And / or, step 103 includes:

[0227] The terminal reports the measurement results of a reference symbol that matches the terminal's altitude and / or longitude and / or latitude and / or speed and / or terminal trajectory.

[0228] It should be noted that "matching the altitude and / or longitude and / or latitude and / or speed and / or trajectory of the terminal" includes the network device being at the same altitude and / or longitude and / or latitude and / or speed as the terminal, or within a certain range. It also includes reference symbols received by the terminal that meet a certain time range, or reference symbols received by the terminal within a certain time window.

[0229] As another optional embodiment, the method further includes:

[0230] Receive a fourth message, which includes at least one of the following:

[0231] First indication information indicating whether the terminal measures reference symbols of network elements from the same cell or frequency point;

[0232] A second indication message indicating whether the terminal needs to report the measurement results of network units in the same cell or frequency.

[0233] It should be noted that the first indication information includes multiple indication units, where the i-th indication unit indicates whether to measure the reference symbol of the i-th network unit. The first indication information also includes whether to measure all reference symbols, i.e., to measure the reference symbols of all network units. This can be indicated by one bit; for example, if the bit is 1 or true, it indicates that the terminal needs to measure all received reference symbols. If the bit is 0 or false, the network can further indicate which one or more network units' reference symbols to measure.

[0234] It should be noted that the second indication information includes multiple indication units, with the i-th indication unit indicating whether to report the measurement results of the i-th network unit. The second indication information also includes whether to report all measurement results, i.e., whether to report the measurement results of all network units. This can be indicated by a single bit; for example, the bit can be set to 1 or true, indicating that the terminal needs to report the measurement results of all network units. The reported measurement results can be those that meet a certain quality threshold.

[0235] For example, if the first instruction information instructs the terminal to measure all reference symbols from different network devices in the same cell or frequency point, then the terminal measures all reference symbols sent by each network device in the first cell respectively; or, for another example, if the first instruction information instructs the terminal not to measure all reference symbols from different network devices in the same cell or frequency point, then the terminal selects a portion of the reference symbols in the first cell for measurement based on the first information.

[0236] For example, if the second instruction information indicates that the terminal needs to report the measurement results of different network devices in the same cell or frequency point, then the terminal will report the measurement results of each network device after completing the reference symbol measurement; or if the second instruction information indicates that the terminal does not need to report the measurement results of different network devices in the same cell or frequency point, then the terminal will report the measurement results of some reference symbols that match its own height or motion trajectory after completing the reference symbol measurement.

[0237] In at least one embodiment of the present invention, to address the issue of how to identify whether a terminal is an aircraft terminal or a regular terminal during cell handover in a stereo cell, the present invention further provides a method comprising:

[0238] The terminal sends fifth information to the network-side device, the fifth information indicating whether the terminal supports first terminal capability information; the first terminal capability information includes at least one of the following:

[0239] The terminal's altitude meets the first altitude threshold;

[0240] The terminal's trajectory meets the first horizontal movement speed threshold;

[0241] The terminal's trajectory satisfies the first vertical movement speed threshold;

[0242] The terminal's trajectory satisfies the first angle movement speed threshold;

[0243] The terminal's transmission power meets the first transmission power threshold;

[0244] The duration of the terminal's stay at the first geographical location within the target time meets the first time threshold; it can be greater than or equal to the first time threshold, or it can be less than or equal to the first time threshold.

[0245] This invention introduces first terminal capability information, enabling terminals that meet the first terminal capability information to operate in a stereo cell or beam. The terminal reports whether the network supports the first terminal capability information. For stereo cells / beams, if the terminal reports support for the first terminal capability information, the terminal can access the network; if the terminal does not support the first terminal capability information, the network can prohibit the terminal from accessing. For ordinary cells, if the terminal reports support for the first terminal capability information, the network can prohibit the terminal from accessing. If an ordinary cell allows terminals supporting the first terminal capability information to access, during handover, among multiple candidate cells / beams, the terminal can be preferentially switched to a stereo cell.

[0246] As another optional embodiment, regarding the question of how the terminal selects the corresponding three-dimensional cell during cell selection or cell reselection, which can also be referred to as the question of how the terminal distinguishes between three-dimensional cells and ordinary cells, the first information in this embodiment of the invention further includes at least one of the following:

[0247] A first identifier indicating whether a cell and / or beam belongs to a first cell;

[0248] Horizontal coverage information for cells and / or beams;

[0249] Vertical coverage information for cells and / or beams;

[0250] Cell and / or beam velocity information;

[0251] The operating frequency of the cell and / or beam;

[0252] Frequency priority of the operating frequencies of cells and / or beams.

[0253] The first cell is also called a three-dimensional cell or a dynamic cell. The first cell includes multiple network devices located at different altitudes and / or latitudes and / or different geographical locations. When a terminal performs cell reselection, if it is an aircraft-type terminal, it will preferentially reselect to the cell / beam with the first identifier. Specifically, Implementation 1: When multiple cells have the same cell quality, the terminal preferentially reselects to the cell with the first identifier; Implementation 2: For cells within a certain quality threshold range, such as cells with cell quality higher than a certain threshold and / or multiple cells whose cell quality differs from the best quality cell by a certain threshold, the terminal will preferentially reselect to the cell with the first identifier; Implementation 3: When multiple beams have the same beam quality, the terminal will preferentially reselect to the beam with the first identifier; Implementation 4: For beams within a certain quality threshold range, such as beams with beam quality higher than a certain threshold and / or multiple beams whose beam quality differs from the best quality beam by a certain threshold, the terminal will preferentially reselect to the beam with the first identifier.

[0254] The horizontal coverage information includes indications of the presence of horizontal coverage enhancement and / or the level of horizontal coverage enhancement (which may include N levels, such as first horizontal coverage, second horizontal coverage, ..., Nth horizontal coverage), and / or horizontal coverage radius information. When a terminal performs cell reselection, if it is an aircraft-type terminal and is moving horizontally, it will preferentially reselect to a cell or beam with a horizontal coverage enhancement indication. Furthermore, based on its own movement trajectory, the terminal can preferentially select a cell or beam with a suitable coverage enhancement level from among multiple cells or beams with horizontal coverage enhancement indications. Specifically, in implementation method 1: when multiple cells have the same cell quality, or multiple cells with cell quality above a certain threshold, or multiple cells whose cell quality differs from the best-quality cell by a certain threshold, the terminal will preferentially reselect to a cell with a horizontal coverage enhancement indication. Further, if multiple cells have horizontal coverage enhancement indications but different coverage enhancement levels, the terminal can select the cell corresponding to the suitable coverage enhancement level according to its own needs. For example, the terminal will move horizontally for a considerable period of time. If there are two cells corresponding to two horizontal coverage levels, and the coverage area of ​​the first coverage level is smaller than that of the second coverage level, then the terminal can preferentially reselect the cell corresponding to the second coverage level.

[0255] The vertical coverage information includes indications of the presence of vertical coverage enhancement, and / or the coverage level of vertical coverage (which may include N coverage enhancement levels, such as first vertical coverage, second vertical coverage, ..., Nth vertical coverage), and / or vertical coverage radius information, etc. When the terminal performs cell reselection, if it is an aircraft-type terminal and is moving in the vertical dimension, it will preferentially reselect to a cell or beam with a vertical coverage enhancement indication. Furthermore, based on its own movement trajectory, the terminal can preferentially select a cell or beam with a suitable coverage enhancement level from multiple cells or beams with vertical coverage enhancement indications. Specifically, in implementation method 1: when multiple cells have the same cell quality, or multiple cells with cell quality higher than a certain threshold, or multiple cells whose cell quality differs from the best-quality cell by a certain threshold, the terminal will preferentially reselect to a cell with a vertical coverage enhancement indication. Further, if multiple cells have vertical coverage enhancement indications but different coverage enhancement levels, the terminal can select the cell corresponding to the suitable coverage enhancement level according to its own needs. For example, if the terminal will continue vertical movement for a considerable period, and there are two cells corresponding to two vertical coverage levels, with the coverage area of ​​the first coverage level being smaller than that of the second, the terminal can preferentially reselect the cell corresponding to the second coverage level. Implementation Method 2: When the terminal's subsequent movement trajectory is uncertain, or when there is a need for both horizontal and vertical movement within a certain period, the terminal can preferentially reselect a cell that has both horizontal and vertical coverage enhancement indicators. Optionally, suitable cells can be further selected for reselection based on the horizontal and vertical coverage enhancement levels.

[0256] This speed information includes indications of whether the cell / beam will move, and / or the direction of movement of the cell / beam (horizontal, vertical, or angular information relative to sea level / land level), and / or the horizontal movement speed or range of the cell / beam, and / or the vertical movement speed or range of the cell / beam, and / or the movement speed or range along a certain angle. If the terminal is currently stationary and detects a cell / beam with good signal quality, but the speed indicator of that cell indicates it is a moving cell / beam (horizontal or vertical), the terminal will not reselect that cell / beam. Alternatively, among multiple candidate cells / beams, if the terminal itself is stationary or moving at low speed, a cell / beam identified as moving has a lower priority for reselection. If the terminal is moving, it can prioritize reselecting a cell / beam whose movement direction and / or speed is more compatible with or closer to its own.

[0257] The frequency priority refers to the fact that for aircraft-type terminals, the operating frequency of stereo dynamic cell / beam is given higher priority than the operating frequency of other cell types. For ordinary terminals, the operating frequency of stereo dynamic cell / beam is given lower priority than the operating frequency of other cell / beam types.

[0258] The velocity information of the cell and / or beam includes at least one of the following:

[0259] The cell and / or beam velocity information includes at least one of the following:

[0260] Fourth indication information indicating whether the cell and / or beam will move;

[0261] The direction of movement of the cell and / or beam; for example, horizontal, vertical, and angular information relative to sea level / land level (such as a first angle);

[0262] Horizontal movement speed information of the cell and / or beam;

[0263] Vertical movement speed information of the cell and / or beam;

[0264] Information on the movement speed of the cell and / or beam along the first angle.

[0265] In summary, in this embodiment of the invention, for a three-dimensional network composed of a ground-based network, an air-based network, and a space-based network, the terminal measures some or all of the reference symbols according to the network configuration, pre-configuration, or pre-agreement, and reports some or all of the measurement results. This can effectively ensure the terminal measurement performance in the three-dimensional network and improve system performance.

[0266] like Figure 2 As shown, this embodiment of the invention also provides a measurement method applied to a network-side device, comprising:

[0267] Step 201: Send the first information to the terminal;

[0268] Step 202: After the receiving terminal measures some or all of the reference symbols, it reports some or all of the measurement results.

[0269] Optionally, in embodiments of the present invention, the first information includes: measurement-related measurement information. The aforementioned reference symbols can be obtained through the measurement information.

[0270] As an optional embodiment, the measurement information includes at least one of the following:

[0271] Period of the reference symbol;

[0272] Duration of the reference symbol;

[0273] Offset value of the reference symbol;

[0274] The period of the measurement interval;

[0275] The duration of the measurement interval;

[0276] The offset value of the measurement interval;

[0277] The third indication information includes at least one of the following: a pre-configured measurement interval, a network control interval, and a concurrent measurement interval.

[0278] The third indication information is used to indicate the type of measurement interval. A pre-configured measurement interval can also be described as a pre-configured measurement gap (Pre-MG). This type of measurement interval is configured by RRC and activated / deactivated via network indication, or activated / deactivated according to certain criteria. A network-controlled small gap (NCSG) can also be described as a network-controlled small gap. This type of measurement interval has a short measurement duration or a small terminal size. Concurrent measurement intervals can also be described as concurrent measurement gaps, meaning that multiple measurement intervals can be configured.

[0279] It should be noted that the above reference symbols are measurement reference symbols, including the Synchronization Signal Block (SSB, which can also be described as SMTC), and / or the Channel State Information Reference Signal (CSI-RS), and / or the Positioning Reference Signal (PRS), etc.

[0280] As an optional embodiment, the method further includes:

[0281] The terminal sends second information, which includes the association between measurement information and a first node and / or beam. This second information can be broadcast or transmitted via Radio Resource Control (RRC) (e.g., configured in the MO). The first node is the first node of the first cell. The terminal can determine the measurement information of the first cell based on the association in the first information.

[0282] Network nodes operating at different altitudes and / or longitudes and / or latitudes have different identifiers, and measurement information can be associated with the relevant identifiers. Measurement information can also be associated with beam identifiers. Beams with different identifiers or different identifier groups (i.e., the group has multiple beams, corresponding to multiple beam IDs, and the beams in the group all belong to the same or the same type of network device) come from different network nodes.

[0283] For example, the second information includes: the association between measurement information and the identifier of the first node; for another example, the second information includes: the association between measurement information and the beam identifier; for yet another example, the second information includes: the association between measurement information and the identifier of the first node and the beam identifier.

[0284] As an optional embodiment, the second information includes at least one of the following:

[0285] At least one set of Synchronization Signal / Physical Broadcast Channel Block Measurement Timing Configuration (SMTC) information corresponding to the Synchronization Signal Block (SSB);

[0286] SMTC offset information; Considering that terrestrial base stations, space base station equipment, and satellites can jointly form a three-dimensional cell, even if all three send signals synchronously, due to different transmission delays, the terminal may receive the reference symbol of the same cell at different times. When the cell only sends one or more fixed sets of SMTCs (multiple sets of SMTCs mean that even if at least two sets of SMTCs are sent, but the SMTCs are not mapped one-to-one with network devices), it can further instruct the terminal to receive the time domain offset of a certain type of network device based on the current SMTC configuration;

[0287] CSI-RS offset information includes the offset information of the CSI-RS configuration for different network devices in the same cell. For different network devices (e.g., network devices at different altitudes and / or longitudes and / or latitudes and / or speeds; or different types of network devices, such as terrestrial networks / base stations, drones, airborne base stations (ATG), hot air balloons, satellites, etc.), the CSI-RS configuration can be different, that is, there are different configurations for different devices, which can also be described as different offset information. The offset information includes at least one of the following: periodic offset, duration offset, and start position offset.

[0288] The relationship between SMTC information and altitude; this altitude range can be the height of the network device relative to sea level or land level, the angle or direction of the network device relative to sea level or land level, or the coverage area of ​​the network device relative to sea level or land level. A single cell or frequency point can transmit multiple sets of SMTCs, and different SMTCs correspond to different altitude thresholds; this altitude includes a specific altitude threshold as well as a certain altitude range. This relationship can also be described as a correspondence.

[0289] The relationship between Channel State Information Reference Signal (CSI-RS) and altitude; this altitude can be the height of the network device relative to the sea level or land level, the angle or direction of the network device relative to the sea level or land level, or the coverage area of ​​the network device relative to the sea level or land level. A single cell or frequency point can transmit multiple sets of CSI-RS, each corresponding to a different altitude threshold; this altitude includes a specific altitude threshold as well as a certain altitude range. This relationship can also be described as a correspondence.

[0290] The relationship between SMTC and beams; beams here include SSB beams, data receive beams (e.g., PDSCH, PDCCH), and data transmit beams (e.g., PUSCH, PUCCH, SRS). Different beams or beam groups correspond to different network devices. The association between SMTC / CSI-RS / location symbols and beams (e.g., establishing an association between SMTC / CSI-RS / location symbols and beam indices) indirectly establishes the association between SMTC / CSI-RS / location symbols and network devices (e.g., establishing an association between SMTC / CSI-RS / location symbols and network device identifiers). Different beams can be distinguished by beam indices.

[0291] The relationship between CSI-RS and beamlines; specifically, this includes the relationship between the CSI-RS measurement window and the beam index; it also includes the relationship between the CSI-RS resource set ID and the beam index; it also includes the relationship between the CSI-RS resource ID and the beam index.

[0292] The relationship between CSI-RS and beamlines includes: specifically, the relationship between the CSI-RS measurement window and the beam index; the relationship between the CSI-RS resource set ID and the beam index; and the relationship between the CSI-RS resource ID and the beam index. Network device identifiers can have multiple values ​​to distinguish between ground-based, airborne, and space-based devices. A single cell or frequency point can transmit multiple SMTCs, each corresponding to a different second identifier value, helping the UE distinguish SMTCs from different network devices within the same cell / frequency point.

[0293] The relationship between CSI-RS and network devices; for example, the relationship between CSI-RS and network device identifiers; network device identifiers can have multiple values ​​to distinguish between ground-based, air-based, and space-based devices. A cell or frequency point can transmit multiple sets of CSI-RS, and different CSI-RS correspond to different third identifier values, helping the UE distinguish CSI-RS from different network devices in the same cell / frequency point;

[0294] The offset information of the positioning symbol includes the offset information of the positioning symbol relative to different network devices in the same cell. For different network devices (such as network devices at different altitudes and / or longitudes and / or latitudes and / or speeds; or different types of network devices, such as terrestrial networks / base stations, drones, airborne base stations (ATG), hot air balloons, satellites, etc.), the configuration of the positioning information can be different, that is, there are different configurations for different devices, which can also be described as different offset information. The offset information includes at least one of the following: periodic offset, duration offset, and starting position offset.

[0295] The relationship between the positioning symbol and its height; this height includes a specific height threshold as well as a certain height range. This relationship can also be described as a correspondence.

[0296] The association between location symbols and beams; beams here include SSB beams, data reception beams (e.g., PDSCH, PDCCH), and data transmission beams (e.g., PUSCH, PUCCH, SRS). Different beams or beam groups correspond to different network devices. This association is achieved indirectly through the linking of SMTC / CSI-RS / location symbols to beams (e.g., linking SMTC / CSI-RS / location symbols to beam indices), thus linking SMTC / CSI-RS / location symbols to network devices (e.g., linking SMTC / CSI-RS / location symbols to network device identifiers). Different beams can be distinguished by beam indices.

[0297] The relationship between location symbols and network devices; for example, the relationship between location symbols and network device identifiers; network device identifiers can have multiple values ​​to distinguish between ground-based devices, air-based devices, and space-based devices.

[0298] The second information may include multiple sets of SMTC information, each corresponding to different network devices in the first cell. Different SMTCs correspond to terrestrial network devices and / or space network base station devices and / or satellites, respectively. Furthermore, it may indicate which network device(s) a particular SMTC corresponds to.

[0299] Optionally, the first node includes at least one of the following:

[0300] Network units operating at different heights;

[0301] Network units operating at different longitudes;

[0302] Network units operating at different latitudes;

[0303] Network units operating at different speeds.

[0304] It should be noted that a network unit can also be described as a network node. Here, a network unit includes at least one of the following: a ground base station, a satellite, a drone, or a hot air balloon.

[0305] As an optional embodiment, the method further includes:

[0306] Send a third message to the terminal, the third message indicating at least one of the following:

[0307] The correlation between the measurement information and different heights;

[0308] The correlation between the measurement information and different longitudes;

[0309] The correlation between the measurement information and different latitudes;

[0310] The correlation between the measurement information and different speeds;

[0311] The measurement information is correlated with different time thresholds. These time thresholds include the terminal receiving time meeting a certain threshold, and / or the terminal receiving time difference meeting a certain threshold. Meeting a certain threshold for the terminal receiving time takes into account the different arrival times of reference symbols sent by network units with different longitudes, latitudes, altitudes, and speeds, thus requiring correlation to distinguish them and assist the terminal in measurement. Meeting a certain threshold for the terminal receiving time difference takes into account the different arrival times of reference symbols sent by network units with different longitudes, latitudes, altitudes, and speeds, allowing measurement information where the arrival time difference meets a certain threshold. Network units with different longitudes, latitudes, altitudes, and speeds can belong to the same cell and be associated with the same PCI.

[0312] As another optional embodiment, before reporting some or all of the measurement results after the receiving terminal has measured some or all of the reference symbols, the method further includes:

[0313] Send a fourth message to the terminal, the fourth message including at least one of the following:

[0314] First indication information indicating whether the terminal measures reference symbols of network elements from the same cell or frequency point;

[0315] A second indication message indicating whether the terminal needs to report the measurement results of network units in the same cell or frequency.

[0316] It should be noted that the first indication information includes multiple indication units, where the i-th indication unit indicates whether to measure the reference symbol of the i-th network unit. The first indication information also includes whether to measure all reference symbols, i.e., to measure the reference symbols of all network units. This can be indicated by one bit; for example, if the bit is 1 or true, it indicates that the terminal needs to measure all received reference symbols. If the bit is 0 or false, the network can further indicate which one or more network units' reference symbols to measure.

[0317] It should be noted that the second indication information includes multiple indication units, with the i-th indication unit indicating whether to report the measurement results of the i-th network unit. The second indication information also includes whether to report all measurement results, i.e., whether to report the measurement results of all network units. This can be indicated by a single bit; for example, the bit can be set to 1 or true, indicating that the terminal needs to report the measurement results of all network units. The reported measurement results can be those that meet a certain quality threshold.

[0318] For example, if the first instruction information instructs the terminal to measure all reference symbols from different network devices in the same cell or frequency point, then the terminal measures all reference symbols sent by each network device in the first cell respectively; or, for another example, if the first instruction information instructs the terminal not to measure all reference symbols from different network devices in the same cell or frequency point, then the terminal selects a portion of the reference symbols in the first cell for measurement based on the first information.

[0319] For example, if the second instruction information indicates that the terminal needs to report the measurement results of different network devices in the same cell or frequency point, then the terminal will report the measurement results of each network device after completing the reference symbol measurement; or if the second instruction information indicates that the terminal does not need to report the measurement results of different network devices in the same cell or frequency point, then the terminal will report the measurement results of some reference symbols that match its own height or motion trajectory after completing the reference symbol measurement.

[0320] In at least one embodiment of the present invention, to address the issue of how to identify whether a terminal is an aircraft terminal or a regular terminal during cell handover in a stereo cell, the present invention further provides a method comprising:

[0321] The receiving terminal sends a fifth piece of information, which is used to indicate whether the terminal supports first terminal capability information; the first terminal capability information includes at least one of the following:

[0322] The terminal's altitude meets the first altitude threshold;

[0323] The terminal's trajectory meets the first horizontal movement speed threshold;

[0324] The terminal's trajectory satisfies the first vertical movement speed threshold;

[0325] The terminal's trajectory satisfies the first angle movement speed threshold;

[0326] The terminal's transmission power meets the first transmission power threshold;

[0327] The duration of the terminal's stay at the first geographical location within the target time meets the first time threshold; it can be greater than or equal to the first time threshold, or it can be less than or equal to the first time threshold.

[0328] This invention introduces first terminal capability information, enabling terminals that meet the first terminal capability information to operate in a stereo cell or beam. The terminal reports whether the network supports the first terminal capability information. For stereo cells / beams, if the terminal reports support for the first terminal capability information, the terminal can access the network; if the terminal does not support the first terminal capability information, the network can prohibit the terminal from accessing. For ordinary cells, if the terminal reports support for the first terminal capability information, the network can prohibit the terminal from accessing. If an ordinary cell allows terminals supporting the first terminal capability information to access, during handover, among multiple candidate cells / beams, the terminal can be preferentially switched to a stereo cell.

[0329] As another optional embodiment, in the cell selection or cell reselection process, to address the issue of how to distinguish between multi-level cells and ordinary cells, the method further includes:

[0330] The sixth information is exchanged with the second cell, and the sixth information includes at least one of the following:

[0331] Does the terminal support the first terminal capability information?

[0332] The first identifier indicating whether a cell and / or beam belongs to a three-dimensional dynamic cell;

[0333] Horizontal coverage information of the cell and / or beam; this horizontal coverage information includes an indication of whether horizontal coverage enhancement exists, the level of horizontal coverage enhancement (first horizontal coverage, second horizontal coverage, etc.), horizontal coverage radius information, etc.

[0334] Vertical coverage information of cells and / or beams; this vertical coverage information includes an indication of whether vertical coverage enhancement exists, the coverage level of vertical coverage (first vertical coverage, second vertical coverage, etc.), vertical coverage radius information, etc.

[0335] Cell and / or beam speed information.

[0336] The second cell can be a regular cell, i.e., a ground network cell, or a three-dimensional cell or a dynamic cell. A three-dimensional cell or a dynamic cell includes multiple network devices located at different altitudes and / or latitudes and / or different geographical locations.

[0337] As another optional embodiment, regarding the question of how the terminal selects the corresponding three-dimensional cell during cell selection or cell reselection, which can also be referred to as the question of how the terminal distinguishes between three-dimensional cells and ordinary cells, the first information in this embodiment of the invention further includes at least one of the following:

[0338] A first identifier indicating whether a cell and / or beam belongs to a first cell;

[0339] Horizontal coverage information of the cell and / or beam; this horizontal coverage information includes an indication of whether horizontal coverage enhancement exists, the level of horizontal coverage enhancement (first horizontal coverage, second horizontal coverage, etc.), horizontal coverage radius information, etc.

[0340] Vertical coverage information of cells and / or beams; this vertical coverage information includes an indication of whether vertical coverage enhancement exists, the coverage level of vertical coverage (first vertical coverage, second vertical coverage, etc.), vertical coverage radius information, etc.

[0341] Cell and / or beam velocity information;

[0342] The operating frequency of the cell and / or beam;

[0343] Frequency priority of the operating frequencies of cells and / or beams.

[0344] The first cell is also called a three-dimensional cell or a dynamic cell. The first cell includes multiple network devices located at different altitudes and / or latitudes and / or different geographical locations. When a terminal performs cell reselection, if it is an aircraft-type terminal, it will preferentially reselect to the cell / beam with the first identifier. Specifically, Implementation 1: When multiple cells have the same cell quality, the terminal preferentially reselects to the cell with the first identifier; Implementation 2: For cells within a certain quality threshold range, such as cells with cell quality higher than a certain threshold and / or multiple cells whose cell quality differs from the best quality cell by a certain threshold, the terminal will preferentially reselect to the cell with the first identifier; Implementation 3: When multiple beams have the same beam quality, the terminal will preferentially reselect to the beam with the first identifier; Implementation 4: For beams within a certain quality threshold range, such as beams with beam quality higher than a certain threshold and / or multiple beams whose beam quality differs from the best quality beam by a certain threshold, the terminal will preferentially reselect to the beam with the first identifier.

[0345] The horizontal coverage information includes indications of the presence of horizontal coverage enhancement, the level of horizontal coverage enhancement (which may include N levels, such as first horizontal coverage, second horizontal coverage, ..., Nth horizontal coverage), and horizontal coverage radius information. When a terminal performs cell reselection, if it is an aircraft-type terminal and is moving horizontally, it will preferentially reselect to a cell or beam with a horizontal coverage enhancement indication. Furthermore, based on its own movement trajectory, the terminal can preferentially select a cell or beam with a suitable coverage enhancement level from among multiple cells or beams with horizontal coverage enhancement indications. Specifically, in implementation method 1: when multiple cells have the same cell quality, or multiple cells with cell quality above a certain threshold, or multiple cells whose cell quality differs from the best-quality cell by a certain threshold, the terminal will preferentially reselect to a cell with a horizontal coverage enhancement indication. Further, if multiple cells have horizontal coverage enhancement indications but different coverage enhancement levels, the terminal can select the cell corresponding to the suitable coverage enhancement level according to its own needs. For example, the terminal will move horizontally for a considerable period of time. If there are two cells corresponding to two horizontal coverage levels, and the coverage area of ​​the first coverage level is smaller than that of the second coverage level, then the terminal can preferentially reselect the cell corresponding to the second coverage level.

[0346] The vertical coverage information includes indications of the presence of vertical coverage enhancement, the coverage level of vertical coverage (which may include N coverage enhancement levels, such as first vertical coverage, second vertical coverage, ..., Nth vertical coverage), and vertical coverage radius information. When the terminal performs cell reselection, if it is an aircraft-type terminal and is moving vertically, it will preferentially reselect to a cell or beam with a vertical coverage enhancement indication. Furthermore, based on its own movement trajectory, the terminal can preferentially select a cell or beam with a suitable coverage enhancement level from multiple cells or beams with vertical coverage enhancement indications. Specifically, in implementation method 1: when multiple cells have the same cell quality, or multiple cells with cell quality above a certain threshold, or multiple cells whose cell quality differs from the best-quality cell by a certain threshold, the terminal will preferentially reselect to a cell with a vertical coverage enhancement indication. Further, if multiple cells have vertical coverage enhancement indications but different coverage enhancement levels, the terminal can select the cell corresponding to the suitable coverage enhancement level according to its own needs. For example, if the terminal will continue vertical movement for a considerable period, and there are two cells corresponding to two vertical coverage levels, with the coverage area of ​​the first coverage level being smaller than that of the second, the terminal can preferentially reselect the cell corresponding to the second coverage level. Implementation Method 2: When the terminal's subsequent movement trajectory is uncertain, or when there is a need for both horizontal and vertical movement within a certain period, the terminal can preferentially reselect a cell that has both horizontal and vertical coverage enhancement indicators. Optionally, suitable cells can be further selected for reselection based on the horizontal and vertical coverage enhancement levels.

[0347] This speed information includes indications of whether the cell / beam will move, the direction of movement (horizontal, vertical, or angle relative to sea level / land level), the horizontal movement speed or range, the vertical movement speed or range, and the movement speed or range along a certain angle. If the terminal is stationary and detects a cell / beam with good signal quality, but the speed indicator of that cell / beam indicates it is moving (horizontal or vertical), the terminal will not reselect that cell / beam. Alternatively, among multiple candidate cells / beams, if the terminal itself is stationary or moving at low speed, cells / beams identified as moving have a lower priority for reselection. If the terminal is moving, it can prioritize reselecting a cell / beam whose movement direction and / or speed are more compatible with or closer to its own.

[0348] The frequency priority refers to the fact that for aircraft-type terminals, the operating frequency of stereo dynamic cell / beam is given higher priority than the operating frequency of other cell types. For ordinary terminals, the operating frequency of stereo dynamic cell / beam is given lower priority than the operating frequency of other cell / beam types.

[0349] The velocity information of the cell and / or beam includes at least one of the following:

[0350] Fourth indication information indicating whether the cell and / or beam will move;

[0351] The direction of movement of the cell and / or beam;
