Technical Field

[0002] The present application relates to the field of communications, and in particular to a measurement method and a measurement device. Background Art

[0003] Non-terrestrial networks (NTNs) introduce distance-based thresholds for measurement initiation strategies for idle and deactivated devices. Specifically, measurements can be categorized as intra-frequency, inter-frequency, and inter-RAT, depending on the relationship between the measurement frequency and the serving cell frequency.

[0004] Terminal devices consume power when performing frequency measurements, especially when measuring different frequencies and frequencies of different systems. The terminal devices waste a lot of power, so how to reduce the power consumption of terminal devices is a problem that needs to be solved.

[0005] Summary of the Invention

[0006] The present application provides a measurement method and a measurement device, which can reduce the measurement power consumption waste of terminal equipment.

[0007] In a first aspect, a measurement method is provided, which is applied to a terminal device, or to an apparatus (such as a chip) in the terminal device, the method comprising: executing or not executing measurement for the target frequency point according to whether the distance between the terminal device and at least one cell under the target frequency point meets a distance condition, the target frequency point is different from a first frequency point, the first frequency point is the frequency point of a service cell of the terminal device, the target frequency point is any one of a plurality of frequency points, and the plurality of frequency points are the frequency points indicated in the system information.

[0008] In the embodiment of the present application, the terminal device performs or does not perform measurement of the target frequency based on whether the distance between the terminal device and at least one cell under the target frequency satisfies a distance condition, and the target frequency is different from the frequency of the serving cell of the terminal device. In other words, for measurement of inter-frequency or inter-system frequencies, the terminal device performs or does not perform measurement of the target frequency based on the relevant distance condition of the cell under the target frequency, and does not perform measurement on other irrelevant frequencies other than the target frequency, thereby reducing measurement power consumption waste of the terminal device.

[0009] In combination with the first aspect, in a possible implementation method, executing or not executing measurement for the target frequency point based on whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition includes: executing or not executing measurement for the target frequency point among the multiple frequency points only based on whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition.

[0010] In the embodiment of the present application, when determining whether to perform measurement on a target frequency, the terminal device may determine whether the distance between the terminal device and at least one cell at the target frequency satisfies a distance condition among multiple frequency points. Because the object compared with the distance condition in the solution of the embodiment of the present application is the at least one cell at the target frequency, rather than the cells at all frequency points, the measurement efficiency of the terminal device at the target frequency can be improved.

[0011] In combination with the first aspect, in a possible implementation method, the execution or non-execution of measurement for the target frequency point based on whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition includes: if the distance condition is met, not performing measurement for the target frequency point; or, if the distance condition is not met, performing measurement for the target frequency point; the distance condition includes: the difference between the first distance and the second distance is less than a first threshold value, the first distance is the distance between the terminal device and the first reference point of the serving cell, and the second distance is the distance between the terminal device and the second reference point of the cell under the target frequency point.

[0012] The distance condition in the embodiment of the present application includes that the difference between the first distance and the second distance is less than the first threshold value. Since the second distance is the distance between the terminal device and the second reference point of the cell under the target frequency point, the terminal device performs or does not perform measurement for the target frequency point according to the distance condition, and does not perform measurement on other irrelevant frequency points other than the target frequency point, thereby reducing the measurement power consumption waste of the terminal device.

[0013] In combination with the first aspect, in a possible implementation method, the second distance is the distance between the terminal device and the second reference point of all cells under the target frequency; or, the second distance is the distance between the terminal device and the second reference point of each cell under the target frequency.

[0014] In combination with the first aspect, in a possible implementation, the first reference point is at least one of the following: the sub-satellite point of the satellite of the service cell, the center point of the service cell, and the first reference point is configured by the network device; the second reference point is at least one of the following: the sub-satellite point of the satellite of the cell under the target frequency, the center point of the cell under the target frequency, and the second reference point is configured by the network device.

[0015] In combination with the first aspect, in a possible implementation method, the execution or non-execution of measurement for the target frequency point based on whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition includes: when a quality condition is met, the execution or non-execution of measurement for the target frequency point based on whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition; the quality condition includes: the reception level value of the serving cell is greater than the second threshold, and the quality value of the serving cell is greater than the third threshold.

[0016] In an embodiment of the present application, when the quality conditions are met, the terminal device further performs or does not perform measurement on the target frequency point based on whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition, which can improve the accuracy of the terminal device in controlling the start of neighboring area measurement, thereby improving the success rate of the terminal device in cell reselection.

[0017] With reference to the first aspect, in a possible implementation, the target frequency is an inter-frequency frequency or an inter-system frequency.

[0018] With reference to the first aspect, in a possible implementation manner, the priority of the first frequency point is greater than or equal to the priority of the target frequency point.

[0019] With reference to the first aspect, in a possible implementation manner, the first threshold is carried in system information.

[0020] In combination with the first aspect, in a possible implementation manner, the second threshold and / or the third threshold is carried in system information.

[0021] In combination with the first aspect, in a possible implementation method, executing or not executing measurement for the target frequency point based on whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition includes: periodically executing or not executing measurement for the target frequency point based on whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition.

[0022] In an embodiment of the present application, the terminal device periodically performs or does not perform measurement on the target frequency point according to the distance condition, which can reduce the power consumption waste of the terminal device. At the same time, it is also beneficial for the terminal device to select a cell with better signal quality when performing cell reselection.

[0023] In combination with the first aspect, in a possible implementation method, the periodic execution or non-execution of measurement for the target frequency point based on whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition includes: when the measurement for the target frequency point is performed within the first period, if it is determined within the second period that the distance between the terminal device and at least one cell under the target frequency point meets the distance condition, the measurement for the target frequency point is stopped, and the start time of the second period is the end time of the first period.

[0024] In the embodiment of the present application, when the terminal device performs measurement for the target frequency in the first cycle, it is possible that the terminal device has not completed measurement of all cells under the target frequency by the end of the first cycle. At the start of the second cycle, if the terminal device determines that the distance between the terminal device and at least one cell under the target frequency satisfies the distance condition, the terminal device may stop measuring the target frequency, thereby further reducing power consumption waste of the terminal device.

[0025] In combination with the first aspect, in a possible implementation method, the periodic execution or non-execution of measurement for the target frequency point according to the preset distance condition includes: if measurement for the target frequency point is not performed within the third period, if it is determined within the fourth period that the distance between the terminal device and at least one cell under the target frequency point does not meet the distance condition, measurement for the target frequency point is performed, and the start time of the fourth period is the end time of the third period.

[0026] In an embodiment of the present application, if the terminal device does not perform measurement on the target frequency point within the third period, it is possible that at the end of the third period, the terminal device determines that the distance between the terminal device and the cell under the target frequency point does not meet the distance condition. In this case, the terminal device can perform measurement on the target frequency point, which is beneficial for the terminal device to select a cell with better signal quality.

[0039] The technical solution in this application will be described below with reference to the accompanying drawings.

[0040] In order to facilitate understanding of the solutions of this application, the following briefly describes the terms that may be involved.

[0041] There are three radio resource control (RRC) states for a terminal device: RRC idle state (idle), RRC connected state (connected), and RRC inactive state (inactive).

[0042] Among them, for a terminal device in the RRC idle state, it means that no RRC connection is established between the terminal device and the base station, data cannot be transmitted between the terminal device and the base station, there is no RRC context, and there is no core network connection.

[0043] For terminal devices in the RRC connected state and the RRC deactivated state, an RRC connection has been established between the terminal device and the base station. However, data can be transmitted between the terminal device and the base station in the RRC connected state, and the RRC context and core network connection have been established. A terminal device in the RRC deactivated state cannot transmit data to or from the base station, but the RRC context and core network connection have been established.

[0044] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, fifth generation (5G) mobile communication system or new radio (NR) communication system and future mobile communication systems.

[0045] FIG1 is a schematic diagram of a wireless communication system 100 applicable to an embodiment of the present application. As shown in FIG1 , the wireless communication system 100 may include one or more network devices, such as the network device 10 shown in FIG1 .

It should be understood that the embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal devices.

It should be understood that in the embodiment of the present application, the specific technology and specific device form adopted by the network device are not limited. In the present application, the network device can refer to the network device itself or a chip used in the network device to complete the wireless communication processing function.

[0049] It should be understood that in the embodiments of the present application, the terminal device or network device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also known as main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a Windows operating system. The application layer includes applications such as browsers, address books, word processing software, and instant messaging software. In addition, the embodiments of the present application do not specifically limit the specific structure of the execution subject of the method provided in the embodiments of the present application.

[0050] In addition, various aspects or features of the present application can be implemented as a method, apparatus, or article of manufacture using standard programming and / or engineering techniques. The term "article of manufacture" as used in this application encompasses a computer program accessible from any computer-readable device, carrier, or medium. For example, computer-readable storage media can include, but are not limited to: magnetic storage devices (e.g., hard disks, floppy disks, or magnetic tapes), optical disks (e.g., compact discs (CDs), digital versatile discs (DVDs), etc.), smart cards, and flash memory devices (e.g., erasable programmable read-only memories (EPROMs), cards, sticks, or key drives, etc.).

[0052] It should be understood that the methods, situations, categories and divisions of the embodiments in the present application are only for the convenience of description and should not constitute special limitations. The features of various methods, categories, situations and embodiments can be combined without contradiction.

[0053] It should also be understood that the “first”, “second” and “third” in the embodiments of the present application are only for distinction and should not constitute any limitation to the present application.

[0054] It should be noted that "and / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0055] As mentioned above, the network equipment can be a satellite network, which offers advantages such as wide coverage and reduced vulnerability to natural disasters. Satellite networks can be deeply integrated with terrestrial mobile communication networks, compensating for the coverage deficiencies of terrestrial mobile networks. This creates a complementary, tightly integrated, and layered fusion network system with terrestrial networks, enabling global information transmission and interaction.

[0056] Satellite communication networks rely on onboard platforms, primarily including low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary Earth orbit (GEO). Based on the relationship between satellites and base stations, they can be categorized into two architectures: transparent payload and regenerative payload.

[0057] In a transparent transmission architecture, satellites only forward signals and lack data processing capabilities. Base stations are located on the ground, and satellites connect to the base stations via a ground-based gateway. Signals between the UE and the base station are transmitted via the satellite, while data processing functions remain at the base station.

[0058] In a regenerative architecture, a satellite has all or part of the base station functionality, meaning it can also perform data processing. This can be categorized into two types: a complete base station located on the satellite, and a base station DU located on the satellite.

[0059] According to the mobility of NTN cells in the ground coverage area, NTN cells can be divided into the following three categories: earth-fixed, quasi-earth-fixed and earth-moving.

[0060] For ground-stationary NTN cells, the coverage area is fixed to a certain area on the ground, i.e., continuous fixed-point coverage. For ground-quasi-stationary NTN cells, the coverage area is fixed to a certain area on the ground for a period of time, and then changes to another area on the ground after a period of time, i.e., fixed-point coverage within a period of time. For ground-mobile NTN cells, the coverage area of ​​this type of NTN cell slides on the ground.

[0061] As mentioned above, for terrestrial quasi-stationary NTN cells and terrestrial mobile NTN cells, the coverage area of ​​the satellite cell may change on the ground, which involves cell reselection of the terminal device.

[0062] For NTN systems, due to the lack of obvious near-far effect of measurement signals, the signal quality-based criteria in satellite systems cannot allow the UE to reasonably control the initiation of measurements. This may result in the UE being unable to select a suitable cell to reside in based on accurate measurement results, affecting the UE's mobility performance.

[0063] NTN introduces distance conditions for the measurement initiation strategy for UEs in idle and deactivated states. Specifically, based on the relationship between the measurement frequency and the serving cell frequency, measurements can be divided into intra-frequency measurement, inter-frequency measurement, and inter-system measurement. Inter-system measurement refers to measurements on systems other than a specific system (for example, for 5G NR systems, measurements on 2G / 3G / 4G (LTE) systems are inter-system measurements). Intra-frequency and inter-frequency measurements are intra-RAT measurements.

[0064] 1. Same frequency measurement

[0065] (1) When the quality condition is met, if the distance condition is met, the UE may not perform measurement on the same-frequency point; if the distance condition is not met, the UE performs measurement on the same-frequency point.

[0066] (2) If the quality condition is not met, the UE performs measurement on the same frequency point.

[0067] 2. Different frequency and different system measurements

[0068] (1) When the quality condition is met, if the cell with different frequencies or different system frequencies meets the distance condition, the UE does not perform measurement on the different frequencies or different system frequencies; if the cell with different frequencies or different system frequencies does not meet the distance condition, the UE performs measurement on all different frequencies or different system frequencies.

[0069] (2) If the quality condition is not met, the UE performs measurements on all inter-frequency points and inter-system frequency points.

[0070] As described above, the condition for measuring inter-frequency points or inter-system points under the quality condition is: if at least one cell does not meet the above distance condition, the terminal device performs signal quality measurement for all cells under inter-frequency points or inter-system points. However, in this case, performing signal quality measurement for all cells under inter-frequency points or inter-system points based only on the distance of a cell under a single inter-frequency point or inter-system point cannot guarantee that the signal quality of all cells under inter-frequency points or inter-system points can be measured, thereby resulting in waste of UE power consumption.

[0071] Based on this, the present application provides a measurement method that divides the measurement granularity into frequency points, and performs or does not perform signal quality measurement of the cell at a certain frequency point based on whether the cell at the frequency point meets the distance condition, which can reduce the measurement power consumption waste of the UE to a certain extent.

[0072] Figure 2 is a schematic diagram of a measurement method provided by an embodiment of the present application. The measurement method can be applied to a terminal device, and the method includes but is not limited to the following steps.

[0073] 210. Execute or not execute measurement on the target frequency point according to whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition. The target frequency point is different from the first frequency point. The first frequency point is the frequency point of the service cell of the terminal device. The target frequency point is any one of multiple frequency points. The multiple frequency points are the frequency points indicated in the system information.

[0074] In the embodiment of the present application, the first frequency is the frequency of the serving cell of the terminal device. The serving cell of the terminal device can be understood as the cell in which the terminal device resides. The frequency of the serving cell of the terminal device can be understood as: the synchronization signal and PBCH block (SSB) frequency of the serving cell of the terminal device or the center frequency of the serving cell of the terminal device.

[0075] The frequency point in the embodiment of the present application can also be understood as frequency. Frequency point refers to a way of expressing the carrier frequency used in radio communication, which can clearly give the numerical value of a specific frequency. Frequency refers to the measure of the number of electromagnetic oscillations contained in a complete cycle of a waveform, usually expressed in Hz. The frequency point is the label of a fixed frequency. For example, for the GSM900 system, the frequency interval of 880~915MHz is 200KHz. According to the frequency interval of 200KHz, 880~915MHz is divided into 125 wireless frequency segments. These 125 wireless frequency segments include 890MHz, 890.2MHz, 890.4MHz, 890.6MHz, 890.8MHz, 891MHz, ..., 915MHz. The numbers of these 125 wireless frequency segments are 1, 2, 3, 4, 5, ..., 124, 125 respectively. These numbers of fixed frequencies are the frequency points.

[0076] The target frequency in the embodiment of the present application is different from the first frequency. The target frequency in the embodiment of the present application can be an inter-frequency frequency or an inter-system frequency. For example, assuming that the frequency indicated by the system information includes 5 frequency points, namely frequency 1, frequency 2, frequency 3, frequency 4, and frequency 5, and the frequency of the service cell of the terminal device is frequency 1, the target frequency in the embodiment of the present application is the frequency point other than frequency 1 among the 5 frequency points, such as frequency 2, frequency 3, frequency 4, and frequency 5. In the embodiment of the present application, the terminal device can perform or not perform measurement on frequency 1 based on the distance condition of the cell under frequency 1.

[0077] In the embodiment of the present application, the measurement of the target frequency point may be to measure the signal quality of the cell of the target frequency point, for example, reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), signal to interference plus noise ratio (SINR), receiving level value (Rx level value) of the serving cell, quality value (quality value) of the serving cell, etc. The reference signal may be an SSB or other signal without limitation.

[0078] The reception level value of the serving cell is abbreviated as Srxlev, and the quality value of the serving cell is abbreviated as Squal.

[0079] Srxlev=Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation-Qoffsettemp

[0080] Squal=Qqualmeas–(Qqualmin+Qqualminoffset)–Qoffsettemp

[0081] Where Qrxlevmeas represents the measured cell RX level value, or the measured cell received power value. Qrxlevmin represents the minimum required RX level in the cell, or the minimum required received power value in the cell. Qrxlevminoffset represents the offset from Qrxlevmin, Pcompensation represents the power compensation value, and Qoffsettemp represents the offset temporarily applied to the cell.

[0082] Qqualmin represents a measured cell RX quality value, Qqualmin represents a minimum required quality level in the cell, and Qqualminoffset represents an offset to Qqualmin.

[0083] In the embodiment of the present application, the terminal device performs or does not perform measurement of the target frequency based on whether the distance between the terminal device and at least one cell under the target frequency satisfies a distance condition, and the target frequency is different from the frequency of the serving cell of the terminal device. In other words, for measurement of inter-frequency or inter-system frequencies, the terminal device performs or does not perform measurement of the target frequency based on the relevant distance condition of the cell under the target frequency, and does not perform measurement on other irrelevant frequencies other than the target frequency, thereby reducing measurement power consumption waste of the terminal device.

[0084] In one embodiment, performing or not performing measurement on the target frequency point according to whether the distance between the terminal device and at least one cell at the target frequency point meets the distance condition includes:

[0085] Among multiple frequency points, measurement of the target frequency point is performed or not performed only according to whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition.

[0086] In an embodiment of the present application, the condition for the terminal device to perform or not perform measurement on the target frequency point is: the terminal device satisfies the distance condition only based on the distance between the terminal device and at least one cell under the target frequency point among multiple frequency points.

[0087] For example, it is still assumed that the frequency points indicated by the system information include five frequency points, namely frequency point 1, frequency point 2, frequency point 3, frequency point 4, and frequency point 5. The frequency point of the serving cell of the terminal device is frequency point 1, and the target frequency point is frequency point 2. If the terminal device needs to determine whether to perform a measurement on frequency point 2, the terminal device only needs to determine whether the distance between itself and at least one cell under frequency point 2 meets the distance condition, without having to determine whether the distance between itself and cells under other frequency points (such as frequency point 3, frequency point 4, and frequency point 5) meets the distance condition. This can reduce power consumption waste of the terminal device and improve the measurement efficiency of the terminal device for the target frequency point.

[0088] In the embodiment of the present application, when determining whether to perform measurement on a target frequency, the terminal device may determine whether the distance between the terminal device and at least one cell at the target frequency satisfies a distance condition among multiple frequency points. Because the object compared with the distance condition in the solution of the embodiment of the present application is the at least one cell at the target frequency, rather than the cells at all frequency points, the measurement efficiency of the terminal device at the target frequency can be improved.

[0089] The above describes whether the terminal device performs or does not perform measurement on the target frequency point based on whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition. The following will specifically introduce the distance condition and the corresponding judgment process.

[0090] In one embodiment, measurement of the target frequency is performed or not performed based on whether the distance between the terminal device and at least one cell under the target frequency satisfies a distance condition, including: if the distance condition is met, measurement of the target frequency is not performed; or, if the distance condition is not met, measurement of the target frequency is performed.

[0091] Among them, the distance conditions include: the difference between the first distance and the second distance is less than the first threshold, the first distance is the distance between the terminal device and the first reference point of the service cell, and the second distance is the distance between the terminal device and the second reference point of the cell under the target frequency.

[0092] The distance condition in the embodiment of the present application includes that the difference between the first distance and the second distance is less than a first threshold. The distance condition can be specifically understood as: the difference between the first distance and the second distance is less than the first threshold.

[0093] In the embodiment of the present application, taking the first distance d1 and the second distance d2 as an example, if the distance condition is met, that is, if d1-d2 < the first threshold, the terminal device does not perform measurement on the target frequency. If the distance condition is not met, that is, d1-d2 ≥ the first threshold, the terminal device performs measurement on the target frequency.

[0094] In the embodiment of the present application, if the distance condition is met, the terminal device does not perform measurement on the target frequency point. This can be understood as: the terminal device may not perform measurement on the target frequency point, or the terminal device is allowed not to perform measurement, and whether to perform measurement is ultimately determined by the terminal device itself.

[0095] The first threshold in the embodiment of the present application may be carried in system information, such as system information block (SIB) 2.

[0096] In one embodiment, the second distance is the distance between the terminal device and the second reference point of all cells at the target frequency; or, the second distance is the distance between the terminal device and the second reference point of each cell at the target frequency.

[0097] In the embodiment of the present application, "all cells" can be understood as cells detected, measured, or indicated by the UE at the target frequency point, and not necessarily all cells deployed at the target frequency point. All cells mentioned here refer to all cells known to the UE.

[0098] "Each cell" can be understood as every cell detected, measured, or indicated by the UE on the target frequency, and is not necessarily the cell deployed on the target frequency. Each cell mentioned here refers to every cell known to the UE.

[0099] As shown in Figure 3, a schematic diagram of a terminal device provided in this application determining whether to measure quality based on a distance condition is provided. Assume that the initial location of the terminal device is in cell 1 at frequency 1. At this time, the serving cell of the terminal device is cell 1, and the frequency of the serving cell of the terminal device is frequency 1. As the terminal device moves, the terminal device approaches or even resides in cell 2 at frequency 2. The terminal device can determine whether to perform a measurement for frequency 2 based on whether the distance between the terminal device and the cell at frequency 2 meets the distance condition.

[0100] Specifically, the cells under frequency point 2 include cell 2 and cell 2'. If the distance between the terminal device and the first reference point of cell 1 is d1, the distance between the terminal device and the second reference point of cell 2 is d2, and the distance between the terminal device and the second reference point of cell 2' is d2', if d1-d2<the first threshold and if d1-d2'<the first threshold, the terminal device does not perform measurement for frequency point 2. If d1-d2≥the first threshold and / or d1-d2'≥the first threshold, the terminal device performs measurement for frequency point 2.

[0101] For example, assuming that the first threshold is 0, d1 is 85, d2 is 90, and d2' is 100, since d1-d2=85-90=-5<0, and d1-d2'=85-100=-15<0, that is, the distances between the terminal device and the reference points of the two cells of frequency point 2 meet the distance conditions, the terminal device does not perform measurements for frequency point 2.

[0102] For another example, assuming that the first threshold is 0, d1 is 100, d2 is 70, and d2' is 90, since d1-d2=100-70=30>0, that is, the distance between the terminal device and the reference point of at least one cell of frequency point 2 does not meet the distance condition, the terminal device performs measurement for frequency point 2.

[0103] The first reference point shown in Figure 3 is the center point of the serving cell, and the second reference point is the center point of the cell at the target frequency. The embodiment of the present application does not limit the positions of the first reference point and the second reference point.

[0104] In one embodiment, the first reference point is at least one of the following: a sub-satellite point of a satellite of a serving cell, a center point of a serving cell, or a first reference point configured by a network device. The second reference point is at least one of the following: a sub-satellite point of a satellite of a cell at a target frequency, a center point of a cell at a target frequency, or a second reference point configured by a network device.

[0105] In this embodiment of the present application, the first reference point can be the sub-satellite point of the satellite serving the cell, and the second reference point can be the sub-satellite point of the satellite serving the cell at the target frequency. The sub-satellite point of a satellite refers to the intersection of the satellite's radial path and the Earth's surface. The sub-satellite point is the projection of the satellite's motion on the Earth's surface, and its trajectory is a line drawn from the satellite's projection on the Earth over a period of time.

[0106] In an embodiment of the present application, the terminal device can obtain the sub-satellite point of the satellite based on the satellite's ephemeris information.

[0107] The first reference point and / or the second reference point may also be configured by the network device or specified by a protocol. For example, the network device configures the terminal device to use a sub-satellite point, or the protocol specifies that the terminal device use a sub-satellite point.

[0108] The first reference point and / or the second reference point configured in the network device may be fixed or dynamically changed.

[0109] It should be noted that the reference points obtained based on different criteria may be the same or different, without limitation. For example, taking the first reference point as an example, the sub-satellite point of the satellite of the terminal device's serving cell and the center point of the terminal device's serving cell may be the same point or different points.

[0110] If the sub-satellite point of the satellite of the service cell of the terminal device and the center point of the service cell are the same point, the terminal device calculates the first distance based on this point.

[0111] If the sub-satellite point of the satellite of the service cell of the terminal device is different from the center point of the service cell, in one implementation, the terminal device can calculate the first distance at any point, such as the terminal device can calculate the first distance at the sub-satellite point of the satellite of the service cell, or the terminal device can calculate the first distance at the center point of the service cell. In another implementation, the terminal device can calculate the first distances based on these two points respectively, such as the terminal device can calculate a first distance at the sub-satellite point of the satellite of the service cell, and at the same time, the terminal device calculates a first distance at the center point of the service cell. Specifically, when making a judgment, the terminal device can judge both of the first distances with the second distance. If the difference between the two first distances and the second distance is less than the first threshold, the terminal device does not perform measurement on the target frequency point.

[0112] It should also be noted that, for multiple cells at the target frequency, the second reference points of the multiple cells may be the same or different.

[0113] For example, still using FIG. 3 as an example, the second reference point of cell 2 at frequency 2 may be the center point of cell 2. The second reference point of cell 2' at frequency 2 may be the center point of cell 2', the sub-satellite point of the satellite of cell 2', or a point configured by a network device.

[0114] The distance condition in the embodiment of the present application includes that the difference between the first distance and the second distance is less than the first threshold value. Since the second distance is the distance between the terminal device and the second reference point of the cell under the target frequency point, the terminal device performs or does not perform measurement for the target frequency point according to the distance condition, and does not perform measurement on other irrelevant frequency points other than the target frequency point, thereby reducing the measurement power consumption waste of the terminal device.

[0115] As shown in FIG4 , it is a schematic diagram of a measurement method provided in an embodiment of the present application.

[0116] The measurement method includes steps 410 to 418 .

[0117] 410, whether the system information broadcasts the first threshold.

[0118] If so, proceed to step 412.

[0119] If not, execute 418.

[0120] 412. Calculate the distance d1 between the UE and the serving cell reference point, and the distance d2 between the UE and the reference points of cells at different frequencies or different system frequencies.

[0121] 414. Whether each cell at the frequency satisfies d1-d2<first threshold.

[0122] If so, execute 416. In 416, measurement of the frequency point is not performed.

[0123] If not, execute 418. 418, perform measurement for the frequency point.

[0124] In an embodiment of the present application, if the first threshold is broadcast in the system information, the terminal device calculates the reference point distance d1 between itself and the serving cell, and calculates the reference point distance d2 between the terminal device and cells in an inter-frequency point or an inter-system frequency point. If all cells in a certain frequency point in the inter-frequency point or the inter-system frequency point satisfy d1-d2<the first threshold, the terminal device does not perform measurement for the frequency point; if at least one cell in the frequency point satisfies d1-d2≥the first threshold, the terminal device performs measurement for the frequency point.

[0125] It should be noted that, if the terminal device needs to execute the method shown in FIG4 , the terminal device may also obtain the satellite ephemeris of the serving cell, and the satellite ephemeris corresponding to different frequency points or different system frequency points.

[0126] It should also be noted that the terminal device may not execute step 410. The terminal device may execute step 412 based on the first threshold broadcast by the system information, or the terminal device may execute step 418 based on the first threshold not broadcast by the system.

[0127] Similarly, the terminal device may not perform step 414, and may perform step 416 based on the distance condition that each cell at the frequency point satisfies d1-d2<the first threshold. Alternatively, the terminal device may perform step 418 based on the condition that at least one cell at the frequency point satisfies d1-d2≥the first threshold.

[0128] In one implementation of the embodiment of the present application, the terminal device may execute steps 412 , 414 , and 416 .

[0129] In another implementation of the embodiment of the present application, the terminal device may execute steps 412 , 414 , and 418 .

[0130] The above embodiment only involves the determination of the distance condition. In some embodiments, the measurement of the target frequency point may be performed or not performed in combination with the quality condition and the distance condition.

[0131] In one embodiment, measurement of the target frequency is performed or not performed based on whether the distance between the terminal device and at least one cell under the target frequency satisfies a distance condition, including: when a quality condition is met, measurement of the target frequency is performed or not performed based on whether the distance between the terminal device and at least one cell under the target frequency satisfies a distance condition.

[0132] The quality condition includes: a reception level value of the serving cell is greater than a second threshold, and a quality value of the serving cell is greater than a third threshold.

[0133] In the embodiment of the present application, the quality condition includes: a reception level value of the serving cell of the terminal device is greater than a second threshold, and a quality value of the serving cell of the terminal device is greater than a third threshold. The reception level value of the serving cell of the terminal device may be Srxlev above, and the quality value of the serving cell of the terminal device may be Squal above.

[0134] The second threshold and the third threshold in the embodiment of the present application are used to control whether the terminal device starts the measurement of the cell with different frequency points or different system frequency points. The second threshold and the third threshold can be carried in the system information, such as SIB2.

[0135] In the embodiment of the present application, when the quality condition is met, that is, the reception level value of the serving cell of the terminal device is greater than the second threshold value, and the quality value of the serving cell of the terminal device is greater than the third threshold value, the terminal device determines whether to perform measurement for the target frequency point based on the distance condition. When the quality condition is not met, that is, the reception level value of the serving cell of the terminal device is less than or equal to the second threshold value, and / or the quality value of the serving cell of the terminal device is less than or equal to the third threshold value, the measurement for the target frequency point is performed.

[0136] For example, taking the second threshold value of -120dBm and the third threshold value of -80dB as an example, if the reception level value of the service cell of the terminal device is -100dBm, and the quality value of the service cell of the terminal device is -70dB, since -100dBm>-120dBm, and -70dB>-80dB, that is, the service cell of the terminal device meets the above quality conditions, therefore, the terminal device can further perform or not perform measurements on the target frequency point according to the distance condition.

[0137] For another example, still taking the second threshold value of -120dBm and the third threshold value of -80dB as an example, if the reception level value of the service cell of the terminal device is -100dBm, and the quality value of the service cell of the terminal device is -90dB, since -100dBm>-120dBm, but -90dB<-80dB, that is, the service cell of the terminal device does not meet the above quality conditions, therefore, the terminal device performs measurement for the target frequency point.

[0138] In an embodiment of the present application, when the quality conditions are met, the terminal device further performs or does not perform measurement on the target frequency point based on whether the distance between the terminal device and at least one cell under the target frequency point meets the distance condition, which can improve the accuracy of the terminal device in controlling the start of neighboring area measurement, thereby improving the success rate of the terminal device in cell reselection.

[0139] As shown in FIG5 , it is a schematic diagram of a measurement method provided in an embodiment of the present application.

[0140] The measurement method includes steps 408 to 418 .

[0141] 408. The UE determines whether the quality of the serving cell meets the quality condition.

[0142] If yes, go to step 410 ; if no, go to step 418 .

[0143] For the contents of steps 410 to 418 , please refer to the relevant description of FIG. 4 and will not be repeated here.

[0144] In an embodiment of the present application, a terminal device determines whether the signal quality of a serving cell satisfies a quality condition. If the quality condition is satisfied, the terminal device further calculates a reference point distance d1 between itself and the serving cell, and a distance d2 between the terminal device and a reference point of a cell at an inter-frequency point or an inter-system frequency point, based on a first threshold value broadcast in the system information. If all cells at a certain frequency point in the inter-frequency point or inter-system frequency point satisfy d1-d2<the first threshold value, the terminal device does not perform measurement for the frequency point; if at least one cell at the frequency point satisfies d1-d2≥the first threshold value, the terminal device performs measurement for the frequency point.

[0145] It should be noted that the terminal device may not execute step 408. The terminal device may execute step 410 based on whether the terminal device's service cell meets the quality condition, or the terminal device may execute step 418 based on whether the terminal device's service cell does not meet the quality condition.

[0146] In one embodiment, the priority of the first frequency point is greater than or equal to the priority of the target frequency point.

[0147] In an embodiment of the present application, the frequency of the service cell of the terminal device is the first frequency. When the priority of the first frequency is greater than or equal to the priority of the target frequency, the terminal device can execute or not execute the measurement of the target frequency based on whether the distance between the terminal device and at least one cell under the target frequency meets the distance condition.

[0148] When the serving cell frequency priority is lower than the neighboring cell frequency priority, the neighboring cell frequency is called a high-priority frequency; when the serving cell frequency priority is equal to the neighboring cell frequency priority, the neighboring cell frequency is called an equal-priority frequency; when the serving cell frequency priority is higher than the neighboring cell frequency priority, the neighboring cell frequency is called a low-priority frequency. Since the priority of the first frequency in the embodiment of the present application is greater than or equal to the priority of the target frequency, the target frequency can be an equal-low-priority frequency.

[0149] In other words, if the target frequency is a frequency of equal lower priority than the first frequency, the terminal device may perform or not perform measurement of the target frequency according to the distance condition.

[0150] In another embodiment, the priority of the first frequency point is lower than the priority of the target frequency point and is not restricted. In this scenario, the target frequency point is a high-priority frequency point. In other words, when the target frequency point is a high-priority frequency point, the terminal device can still perform or not perform measurement on the target frequency point based on the distance condition.

[0151] Generally, the system information will broadcast the priority of the frequency. In the embodiment of the present application, the target frequency is different from the first frequency. The priority of the first frequency can be carried in SIB2, and the priority of the target frequency can be carried in SIB4 or SIB5.

[0152] The above embodiment points out that the terminal device may perform or not perform measurement for the target frequency point according to the distance condition. The time when the terminal device performs or does not perform measurement for the target frequency point according to the distance condition is described in detail below.

[0153] In one embodiment, measurement of the target frequency is performed or not performed based on whether the distance between the terminal device and at least one cell under the target frequency satisfies a distance condition, including: periodically performing or not performing measurement of the target frequency based on whether the distance between the terminal device and at least one cell under the target frequency satisfies a distance condition.

[0154] In an embodiment of the present application, a terminal device may periodically perform or not perform measurement on a target frequency point based on a distance condition. For example, assuming that the duration of a cycle in an embodiment of the present application is a preset duration, the terminal device may perform or not perform measurement on a target frequency point based on a distance condition every other cycle, or may perform or not perform measurement on a target frequency point based on a distance condition every other cycle.

[0155] The preset duration in the embodiment of the present application can be configured by the network device or determined by the terminal device itself, without limitation.

[0156] In one embodiment, measurement of the target frequency is periodically performed or not performed based on whether the distance between the terminal device and at least one cell under the target frequency satisfies a distance condition, including: when measurement of the target frequency is performed within a first period, if it is determined within a second period that the distance between the terminal device and at least one cell under the target frequency satisfies the distance condition, measurement of the target frequency is stopped, and the start time of the second period is the end time of the first period.

[0157] In the embodiment of the present application, it is assumed that the duration corresponding to the first period is the first preset duration, and the duration corresponding to the second period is the second preset duration. Taking Figure 3 above as an example, assuming that the target frequency is frequency 2, the first preset duration and the second preset duration are 1s. For example, the terminal device performs measurement on frequency 2 according to the distance condition within the first preset duration from 9:00:00 to 9:00:01. Within the first preset duration, the terminal device needs to perform measurement on multiple cells under frequency 2. It is possible that the terminal device has not completed the measurement of multiple cells under frequency 2 until the end of the first preset duration. Therefore, for the second preset duration, the terminal device can still confirm whether to perform measurement on frequency 2 according to the distance condition. If the terminal device confirms that it does not perform measurement on frequency 2 according to the distance condition at 9:00:01, the terminal device can stop measuring frequency 2, thereby reducing the power consumption waste of the terminal device.

[0158] The embodiment of the present application does not impose any specific restrictions on the duration corresponding to the first period and the duration corresponding to the second period. The duration corresponding to the first period and the duration corresponding to the second period may be equal or different.

[0159] For example, the first cycle includes a duration of N cycles, and the second cycle includes a duration of M cycles, where N may be equal to M, or may be less than M, or may be greater than M.

[0160] In one embodiment, measurement of the target frequency is periodically performed or not performed based on whether the distance between the terminal device and at least one cell under the target frequency satisfies a distance condition, including: if measurement of the target frequency is not performed within the third period, if it is determined within the fourth period that the distance between the terminal device and at least one cell under the target frequency does not satisfy the distance condition, measurement of the target frequency is performed, and the start time of the fourth period is the end time of the third period.

[0161] In the embodiment of the present application, it is assumed that the duration corresponding to the third period is the third preset duration, and the duration corresponding to the fourth period is the fourth preset duration. Still taking Figure 3 above as an example, assuming that the third preset duration and the fourth preset duration are 1s, for example, the terminal device does not perform measurement on frequency 2 according to the distance condition in the time period of 10:00:00 to 10:00:01. Within the third preset duration, the terminal device does not need to perform measurement on frequency 2. It is possible that at the end moment of the third preset duration, that is, the initial moment of the fourth preset duration, the terminal device needs to perform measurement on frequency 2. For the time period of the fourth preset duration, the terminal device can still confirm whether to perform measurement on frequency 2 according to the distance condition. If the terminal device confirms to perform measurement on frequency 2 according to the distance condition at 10:00:01, the terminal device can perform measurement on frequency 2, which is beneficial for the terminal device to select a cell with better signal quality.

[0162] Similarly, the embodiment of the present application does not impose any specific restrictions on the duration corresponding to the third period and the duration corresponding to the fourth period. The duration corresponding to the third period and the duration corresponding to the fourth period may be equal or different.

[0163] In summary, the terminal device can periodically perform or not perform measurement on the target frequency point according to the distance condition to reduce the power consumption waste of the terminal device. At the same time, it is beneficial for the terminal device to select a cell with relatively good signal quality when performing cell reselection.
