[0022] In conjunction with the first aspect, in some possible implementations of the first aspect, the measurement relaxation criterion is also used to indicate first time information, which indicates the time at which the measurement relaxation is performed.

[0023] Optionally, the first time information includes: a first time point, which is used to indicate that the measurement relaxation was performed before the first time point.

[0024] Optionally, the first time information includes: a first duration and a second time point, the first duration and the second time point being used to indicate that a measurement of relaxation is performed within the first duration starting from the second time point;

[0025] Optionally, the first time information includes a third time point and a fourth time point, the third time point being earlier than the fourth time point, the third time point and the fourth time point being used to indicate that a measurement relaxation was performed between the third time point and the fourth time point.

[0026] By combining real-time information, the terminal can determine whether the measurement relaxation criteria are met within a specific time period based on its time with satellite service, and determine the time period within which measurement relaxation should be performed. This not only reduces the terminal's power consumption, but also avoids starting the judgment on whether the measurement relaxation criteria are met from the start time of satellite service to the terminal, thus improving the effectiveness of measurement relaxation.

[0027] In conjunction with the first aspect, in some possible implementations of the first aspect, the measurement relaxation criterion is further used to indicate first parameter information and / or second parameter information; wherein the first parameter information is used to assess whether the serving cell where the terminal is located meets the good cell service quality criterion or the non-cell edge criterion, and the second parameter information is used to assess whether the low mobility criterion is met; and the measurement relaxation based on the measurement relaxation criterion includes performing measurement relaxation on one or more of the following: RLM, BFD, or RRM.

[0028] In conjunction with the first aspect, in some possible implementations of the first aspect, the measurement relaxation criterion is further used to indicate first parameter information and / or second parameter information; wherein the first parameter information is used to assess whether the serving cell where the terminal is located meets the good cell service quality criterion or the non-cell edge criterion, and the second parameter information is used to assess whether the low mobility criterion is met; and the measurement relaxation based on the measurement relaxation criterion, performing measurement relaxation on one or more of the following: RLM, BFD, or RRM, includes: performing measurement relaxation on one or more of the following: RLM, BFD, or RRM based on the reference location and first time information, and the first parameter information and / or the second parameter information.

[0029] By combining good cell service quality standards or non-cell edge standards, and / or low mobility standards, the terminal can not only reduce its power consumption, but also improve the effectiveness of measurement relaxation.

[0030] In conjunction with the first aspect, in some possible implementations of the first aspect, the method further includes: reporting one or more of the following measured relaxation states: RLM, BFD, or RRM.

[0031] The measurement relaxation state can be understood as whether the measurement relaxation criteria are met. As an example and not a limitation, 1 can be used to indicate that the measurement relaxation criteria are met, or that the measurement relaxation state is in place, or that measurement relaxation is being performed; 0 can be used to indicate that the measurement relaxation criteria are not met, or that the measurement relaxation state is not in place, or that measurement relaxation is not being performed. This application does not limit this.

[0032] Secondly, a method for measuring relaxation in an NTN is provided. This method can be executed by a communication device, which can be a terminal, a component configured in the terminal (such as a chip, chip system, etc.), or a logic module or software capable of realizing all or part of the terminal functions. This application does not limit the scope of this application.

[0034] Based on the above scheme, by using the first-time information, the terminal can determine whether the measurement relaxation criteria are met within a specific time period based on its time with the satellite service, and determine within what time period to perform measurement relaxation. This not only reduces the terminal's power consumption, but also avoids starting the judgment on whether the measurement relaxation criteria are met from the start time of the satellite service to the terminal, thereby improving the effectiveness of measurement relaxation.

[0035] In conjunction with the second aspect, in some possible implementations of the first aspect, the first time information includes: a first time point, which is used to indicate that a measurement of relaxation was performed prior to that first time point.

[0036] This first time point is earlier than the time when the serving satellite associated with the NTN serving cell ceased service.

[0037] In conjunction with the second aspect, in some possible implementations of the first aspect, the first time information includes: a first duration and a second time point, the first duration and the second time point being used to indicate that a measurement of relaxation is performed within the first duration starting from the second time point.

[0038] The second time point plus the first duration is earlier than the time when the serving satellite associated with that NTN serving cell ceased service.

[0039] In conjunction with the second aspect, in some possible implementations of the first aspect, the first time information includes a third time point and a fourth time point, the third time point being earlier than the fourth time point, the third time point and the fourth time point being used to indicate that a measurement of relaxation is performed between the third time point and the fourth time point.

[0040] The fourth time point is earlier than the time when the serving satellite associated with the NTN serving cell ceased service.

[0043] Optionally, the device further includes a communication interface, to which the processor is coupled. The communication interface is used to receive signals from other communication devices outside the device and transmit them to the processor, or to send signals from the processor to other communication devices outside the device. Exemplarily, the communication interface may be a transceiver, circuit, bus, module, pin, or other type of communication interface.

[0044] Optionally, the device further includes a memory, to which the processor is coupled. The memory stores program instructions and data. The memory is coupled to the processor, which, when executing the instructions stored in the memory, can implement the methods described in the preceding aspects.

[0045] Fifthly, this application provides a computer-readable storage medium storing a computer program or instructions that, when executed, implement the methods described in the first aspect, the second aspect, and any possible implementation of the first aspect and the second aspect.

[0064] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0065] To facilitate understanding of the technical solution provided in this application, the following points are made first:

[0066] First, in this application, the terms “comprising” and “having” and any variations thereof are intended to cover non-exclusive inclusion, for example, an apparatus, system, product or device that includes a series of modules, units or units is not necessarily limited to those modules, units or units that are explicitly listed, but may include other modules, units or units that are not explicitly listed or that are inherent to such apparatus, system, product or device.

[0067] Second, in this application, "at least one (type or quantity)" refers to one or more items, and "multiple items" refers to two or more items. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates an "or" relationship between the preceding and following related objects, but it does not exclude the possibility of indicating an "and" relationship; the specific meaning can be understood in context. "At least one (type) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (type) of a, b, or c can represent: a, b, c; a and b; a and c; b and c; or a and b and c. Here, a, b, and c can be single or multiple.

[0068] Third, in this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to a terminal" can be understood as the destination of the information being the terminal, which may include direct transmission via the air interface or indirect transmission via the air interface from other units or modules. "Receive information from a base station" can be understood as the source of the information being the base station, which may include direct reception from the base station via the air interface or indirect reception from the base station via the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0069] In other words, sending and receiving can be done between devices, such as between an NTN device and a terminal; or it can be done within a device, such as between components, modules, chips, software modules, or hardware modules within a device via a bus, wiring, or interface.

[0070] Fourth, in this application, "when," "under the circumstances," "if," and "if" all refer to the device making a corresponding action under certain objective circumstances, and are not time-limited, nor do they require the device to make a judgment action when it is implemented, nor do they mean that there are other limitations.

[0071] Fifth, in this application, the words "example," "exemplarily," "for example," or "such as" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "example," "exemplarily," "for example," or "such as" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "example," "exemplarily," "for example," or "such as" is intended to present the relevant concepts in a specific manner.

[0072] Sixth, the terms "first," "second," "third," and "fourth" are used to distinguish identical or similar items with essentially the same function and purpose. For example, "first preset threshold" and "second preset threshold" are used to distinguish different preset thresholds; "first parameter information" and "second parameter information" are used to distinguish different parameter information; "first distance threshold," "second distance threshold," "third distance threshold," and "fourth distance threshold" are used to distinguish different thresholds; and "first time point," "second time point," "third time point," and "fourth time point" are used to distinguish different time points, without specifying their order. Those skilled in the art will understand that the terms "first," "second," "third," and "fourth" do not limit the quantity or execution order, and that the terms "first," "second," "third," and "fourth" do not necessarily imply that they are different.

[0073] Seventh, in this application, "preset" can be understood as predefined, defined, pre-defined, stored, pre-stored, pre-negotiated, or pre-configured, etc.

[0074] Eighth, in this application, the indication may include explicit indication (also known as direct indication) and implicit indication (also known as indirect indication). Explicit indication information A means including information A; implicit indication information A means indicating information A through the correspondence between information A and information B and direct indication information B. The correspondence between information A and information B may be predefined, pre-stored, pre-burned, or pre-configured; or it may refer to indicating information A through information B and preset rules.

[0075] Ninth, in this application, a terminal may also be referred to as a terminal device, terminal equipment, user equipment (UE), mobile station, mobile terminal, etc. A terminal may include, but is not limited to: mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) device, augmented reality (AR) device, mixed reality (MR) device, extended reality (XR) device, wireless terminal in industrial control, vehicle-mounted equipment, wireless terminal in autonomous driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, wearable device, video player, full-range projector, etc. This application does not limit the specific type of terminal.

[0076] Tenth, in this application, the NTN equipment can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a gNB, or a base station in a future mobile communication system, etc. This application does not limit the type of NTN equipment.

[0077] Eleventh, in this application, the ephemeris information and epoch time of the serving satellite associated with the NTN serving cell can also be understood as the movement trajectory and epoch time of the NTN equipment (e.g., satellite, UAV, or high-altitude platform) associated with the NTN serving cell. Furthermore, in this application, the terminal performing RRM measurement relaxation on the NTN serving cell and / or its neighboring cells can be understood as the terminal being able to perform RRM measurement relaxation on the same frequency and / or different frequencies.

[0078] To better understand the methods provided in the embodiments of this application, the technical terms related to NTN will be explained in detail below with reference to the accompanying drawings.

[0079] 1. NTN: Compared to terrestrial network communication (or land-based communication), NTN communication has advantages such as large coverage area and flexible networking. NTN communication involves networking using equipment such as drones, high-altitude platform stations, and satellites to provide terminals with data transmission, voice communication, and other services. High-altitude platform station (HAPS) equipment is generally located at an altitude of 8–50 kilometers above the ground.

[0080] 2. NTN payload: A network node carried on a satellite or high-altitude platform station, providing connectivity between the service link and the feeder link. An NTN payload can be a transparent payload or a regenerative payload.

[0081] 3. Feeder link: The wireless link between the NTN gateway and the NTN payload.

[0082] 4. Service Link: Also known as the business link, it is the wireless link between the NTN payload and the terminal.

[0083] The following will combine Figure 1 and Figure 2 This section explains common network architectures used in NTN communication.

[0084] Figure 1 This is a schematic diagram of a network architecture for NTN provided in an embodiment of this application.

[0085] Figure 1 This paper illustrates a non-regenerative satellite NTN network architecture, which may include core network (CN) elements (e.g., access and mobility management function (AMF) elements / user plane function (UPF) elements), ground stations, satellites, and terminals. In this NTN network architecture, non-terrestrial NR access is provided to terminals through NTN payloads and NTN gateways. The NTN gateway is located at a ground station on the Earth's surface, providing connectivity to the NTN payload via a feeder link. The NTN payload is carried by network nodes on a satellite (or high-altitude platform station), providing connectivity between the service link and the feeder link, i.e., as shown... Figure 1The satellite and ground station shown can be combined to have base station (e.g., gNB) capabilities. In other words, in this network architecture, the satellite and ground station constitute a base station. During communication between the base station and the terminal, the base station interconnects with the terminal via the NR Uu interface and with AMF / UPF network elements via the next-generation (NG) interface. The NTN payload can forward the radio protocol received from the terminal via the serving link to the NTN gateway via the feeder link. The NTN payload supports the following connections: one NTN gateway can serve multiple NTN payloads; or, one NTN payload can be served by multiple NTN gateways.

[0086] Figure 2 This is a schematic diagram of another network architecture of NTN provided in the embodiments of this application.

[0087] Figure 2 An NTN network architecture for a regenerating satellite is shown, which may include CN network elements (e.g., AMF network elements / UPF network elements), ground stations, satellites, and terminals.

[0088] like Figure 2 As shown, when a satellite operates in regenerative mode, it possesses data processing capabilities and functions as a base station, or partially as one. In this mode, the satellite can be considered a base station; that is, a base station can be deployed on the satellite, or the functions of a base station, or some functions, are integrated onto the satellite. The satellite can communicate with terminals via the NR Uu interface, with the CN via the NG interface, and with other satellites via the Xn interface. The NTN gateway is located at a ground station on the Earth's surface, using a feeder link to provide connectivity to the NTN payload. The NTN payload is carried by network nodes on the satellite (or high-altitude platform station), providing connectivity between different satellites through inter-satellite links. In this network architecture, the satellite can be viewed as an NG-RAN node.

[0089] exist Figure 1 or Figure 2 In the network architecture shown, the satellites can be geostationary earthorbit (GEO) satellites, medium earth orbit (MEO) satellites, or low earth orbit (LEO) satellites. The satellites can also be replaced by other NTN devices such as HAPS equipment and drones. This application does not limit the type of satellites.

[0090] Figure 1 and Figure 2 This is merely an example and should not be construed as limiting the scope of this application.

[0091] 5. Non-geosynchronous orbit (NGSO): An orbit centered on the Earth whose period does not match the Earth's rotation. NGSO can include LEO and MEO.

[0092] 6. Geosynchronous orbit: Also known as a geostationary orbit, it is an orbit centered on the Earth, located approximately 35,786 km above the Earth's surface, and synchronized with the Earth's rotation. More precisely, a geosynchronous orbit is a non-inclined geosynchronous orbit, meaning it lies within the Earth's equatorial plane.

[0093] 7. GEO satellite: also known as geostationary orbit satellite. The orbital altitude of GEO satellite is 35,786 km. The advantage of GEO satellite communication is that it can remain relatively stationary with respect to the ground and provide a large coverage area.

[0094] 8. MEO satellites: For example, MEO satellites orbit at altitudes ranging from 2000km to 35786km. The advantage of MEO satellite communication is that global coverage can be achieved with a relatively small number of satellites. MEO satellites are mainly used for positioning and navigation.

[0095] 9. LEO satellites: For example, LEO satellites have an orbital altitude of 300km to 2000km. LEO satellites have a lower orbital altitude than MEO and GEO satellites, and have the advantages of low data transmission delay, low transmission loss and relatively low launch cost.

[0096] The NTN network architecture can support the following types of service links: fixed earth service links, quasi-earth-fixed service links, and earth-moving service links.

[0097] Earth-based fixed service links are provided by beams, continuously covering the same geographical area, such as in the case of geostationary orbit satellites. Quasi-Earth-based fixed service links are provided by beams, covering one geographical area in one time period and a different geographical area in another time period, such as in the case of NGSO satellites generating steerable beams. Earth-based mobile service links are provided by beams whose coverage area slides across the Earth's surface, such as in the case of NGSO satellites generating fixed or non-steerable beams.

[0098] Understandably, gNBs using NGSO satellites can provide quasi-Earth fixed service links or Earth mobile service links, while gNBs operating using GSO satellites can provide Earth fixed service links.

[0099] 10. RLM: The terminal monitors downlink radio link quality based on the reference signal configured as an RLM-reference signal (RS) resource, and detects the downlink radio link quality of the primary cell (PCell) or primary serving cell (PSCell) in NR. When no RLM-RS resource is configured, the terminal can monitor the downlink radio link quality of the synchronization signal block (SSB).

[0100] In discontinuous reception (DRX) mode operation, the terminal evaluates the radio link quality once per indication period. The terminal can determine the indication period as the maximum of the shortest period for radio link monitoring resources and the DRX period.

[0101] In non-DRX mode operation, the terminal evaluates the radio link quality once per indication period. The terminal can determine the indication period as the maximum of the shortest period for monitoring radio link resources and 10 milliseconds (ms).

[0102] 11. BFD: gNB configures the beam failure detection reference signal on each serving cell to the terminal. When the number of beam failure instances indicated from the physical layer reaches the configured threshold value before the configured timer expires, the terminal announces a beam failure.

[0103] 12. RRM: Under limited bandwidth conditions, it provides quality of service assurance for wireless user terminals within the network. In situations such as uneven distribution of network traffic and fluctuations in channel characteristics due to channel attenuation and interference, it flexibly allocates and dynamically adjusts the available resources of the wireless transmission part and the network to maximize the utilization of the wireless spectrum, prevent network congestion, and maintain the minimum possible signaling load.

[0104] 13. Connected terminal: The terminal is in connected state. A radio resource control (RRC) connection has been established between the terminal and the NTN device (e.g., a satellite base station), allowing data transmission and / or signaling interaction between the terminal and the NTN device.

[0105] 14. Idle Terminal: The terminal is in an idle state, and no RRC connection has been established between the terminal and NTN equipment (such as a satellite base station). Although in an idle state, the terminal still maintains basic communication with the network in order to quickly respond to network calls or data transmission requests.

[0106] 15. Inactive Terminal: The terminal is in an inactive state. The RRC connection between the terminal and the NTN device (e.g., a satellite base station) is suspended, but certain context information is still maintained to facilitate quick connection recovery. It can be understood that the inactive state is a state between the connected state and the idle state.

[0107] 16. Low Mobility Standard: The quality of the serving cell changes within a certain threshold range over a given period of time. The low mobility standard can also be called the stationary standard or the stability standard; in other words, the principle behind the stationary standard or the stability standard is the same as that of the low mobility standard.

[0108] For example, the time period threshold is T threshold The threshold for the change in serving cell quality (dB) or serving cell received level (RX level value (dB)) is S. threshold If, in T threshold The internal judgment determines that the change in the quality of the serving cell is less than the threshold S. threshold If so, it can be considered that the low mobility criterion is met.

[0109] 17. Good Serving Cell Quality Criteria: For connected terminals, when the downlink radio link quality on the configured RLM-RS resources is evaluated to be better than a preset threshold (e.g., threshold Qin + X dB), it is considered to meet the relaxed measurement criteria for good serving cell quality of RLM. Similarly, when the downlink radio link quality on the configured BFD-RS resources is evaluated to be better than a preset threshold (e.g., threshold Qin + X dB), it is considered to meet the relaxed measurement criteria for good serving cell quality of BFD. Wherein: TS 38.133 specifies that Qin,X is the parameter offset of the serving cell being evaluated.

[0110] 18. RRM Measurement: Connected-state terminals measure multiple beams (at least one) of the serving or non-serving cell and average the measurement results (power values) to obtain cell quality. Idle-state terminals and inactive terminals select a suitable cell when the measured cell attributes meet the cell selection criteria; idle-state terminals and inactive terminals measure the attributes of the serving cell and neighboring cells to initiate the reselection process.

[0111] For idle or inactive terminals, the good serving cell quality standard can be referred to as the "not at cell edge" standard. That is, when a terminal determines that its serving cell's received signal level is higher than a preset threshold, or that the serving cell's received quality value is higher than a preset threshold, the terminal can determine that it meets the not at cell edge standard.

[0112] In NTN, the terminal performs RLM, BFD, and RRM. However, the terminal consumes a relatively large amount of power when performing RLM, BFD, or RRM. To address this issue, embodiments of this application provide a method for measurement relaxation in NTN. The terminal can obtain a measurement relaxation standard, which can be used to indicate the reference position associated with the NTN cell to be measured. The terminal performs measurement relaxation of RLM, BFD, or RRM for the NTN cell to be measured based on the measurement relaxation standard, thereby reducing the terminal's power consumption.

[0113] The method for measuring relaxation in NTN provided in this application will be described in detail below with reference to the accompanying drawings.

[0114] For the sake of brevity, a satellite base station will be used as an example of an NTN device in the following description. It is understood that the base station mentioned later can also be understood as a satellite base station.

[0115] Figure 3 This is a schematic flowchart of a method for measuring relaxation in NTN provided in an embodiment of this application.

[0116] like Figure 3 The method 300 shown may include steps 310 and 320. This method 300 can be executed by a communication device, which may be a terminal, a component configured in the terminal (such as a chip, chip system, etc.), or a logic module or software capable of implementing all or part of the terminal's functions; this application does not limit this. The following uses a terminal as an example to describe each step of this method 300 in detail.

[0117] In step 310, the terminal acquires a measurement relaxation criterion, which is used to indicate a reference location associated with the NTN cell to be measured.

[0118] The reference location is associated with the NTN cell to be measured. It can be understood that each NTN cell to be measured corresponds to a reference location, and the reference locations of different NTN cells to be measured can be different.

[0119] In the embodiments of this application, the reference location may be a point on the Earth's surface, or it may be an ellipsoidal point close to the Earth's surface. The reference location may include latitude and longitude, and the specific format and definition of the reference location can refer to the format and definition of an ellipsoidal point in the TS 37.355 protocol.

[0120] In one possible implementation, the reference location can be a fixed reference location. This implementation is applicable to quasi-fixed cells.

[0121] In another possible implementation, the reference location could be a reference location corresponding to a specific time reference, indicated by epoch time. This implementation could be applied to earth-moving cells.

[0122] The terminal acquiring measurement relaxation criteria can be understood as the terminal receiving all or part of the measurement relaxation criteria from other devices (such as base stations), and some measurement relaxation criteria can be configured on the terminal.

[0123] For example, the measurement relaxation standard can be carried in an NTN cell broadcast message, and the terminal can receive the NTN cell broadcast message to obtain the measurement relaxation standard. Alternatively, the measurement relaxation standard can be carried in an RRC-specific message, such as an RRC reconfiguration message or an RRC release message, and the terminal can receive the RRC-specific message to obtain the measurement relaxation standard.

[0124] For example, a base station or NTN cell can send a measurement relaxation standard carrying the aforementioned reference location to a terminal via an NTN cell broadcast message or an RRC proprietary message. Accordingly, the terminal can receive the measurement relaxation standard from the base station via the NTN cell.

[0125] In step 320, the terminal performs measurement relaxation on one or more of the following based on the measurement relaxation criteria: RLM, BFD, or RRM.

[0126] After obtaining the measurement relaxation standard, the terminal can perform one or more of the measurement relaxations of RLM, BFD, or RRM of the NTN cell to be measured based on the measurement relaxation standard.

[0127] In the embodiments of this application, the measurement relaxation of the RLM of the NTN cell to be measured can be implemented in several possible ways, including but not limited to the following:

[0128] In one possible implementation, the connected terminal can enable a longer measurement period (or evaluation period, or sampling interval) to measure the air interface service quality of the NTN cell under test based on the RLM reference signal, namely channel-state information (CSI)-RS (CSI-RS) and / or SSB.

[0129] In another possible implementation, the connected terminal may not perform air interface link detection on the NTN cell to be measured within a preset time period (e.g., 10 minutes, 30 minutes, 1 hour, 2 hours, etc.). That is, the connected terminal may stop air interface link detection on the NTN cell to be measured within the preset time period.

[0130] In the embodiments of this application, the measurement relaxation of BFD for the NTN cell to be measured can include, but is not limited to, the following possible implementations:

[0131] In one possible implementation, the connected terminal can enable a longer measurement period (or evaluation period, or sampling interval) to measure the air interface service quality or beam service quality of the NTN cell to be measured based on CSI-RS and / or SSB and / or RLM-RS.

[0132] In another possible implementation, the connected terminal may not perform beam failure detection measurement on the NTN cell to be measured within a preset time period (e.g., 10 minutes, 30 minutes, 1 hour, 2 hours, etc.). That is, the connected terminal may stop performing beam failure detection on the NTN cell to be measured within the preset time period.

[0133] In the embodiments of this application, for idle or inactive terminals, the relaxation of RRM measurement for neighboring cells of the NTN serving cell can include, but is not limited to, the following possible implementations:

[0134] In one possible implementation, an idle or inactive terminal can enable a longer measurement period (or evaluation period, or sampling interval) to perform RRM measurements on neighboring cells of the NTN serving cell, such as RRM measurements for inter-frequency or inter-air access technology (RAT). As an example, and not a limitation, if the service quality or received signal level of the NTN serving cell is below a first preset threshold but above a second preset threshold (the second preset threshold is lower than the first preset threshold, which can be understood as the minimum preset threshold), the idle or inactive terminal can extend the measurement period to a fixed value, such as 60 seconds, 70 seconds, 80 seconds, 90 seconds, etc. Alternatively, if the service quality or received signal level of the NTN serving cell is above the second preset threshold, the idle or inactive terminal can extend the measurement period to a fixed value, such as 60 seconds, 70 seconds, 80 seconds, 90 seconds, etc. Alternatively, if the service quality or received signal level of the NTN serving cell is lower than the first preset threshold, the idle or inactive terminal can extend the measurement period to a certain value, such as 60s, 70s, 80s, 90s, ...

[0135] In another possible implementation, during a preset time period (e.g., 10 minutes, 30 minutes, 1 hour, 2 hours, etc.), an idle or inactive terminal may not perform RRM measurements on neighboring cells of the NTN serving cell. That is, during the preset time period, an idle or inactive terminal may stop performing RRM measurements on neighboring cells of the NTN serving cell.

[0136] It should be noted that in this application, idle or inactive terminals can also perform RRM measurement relaxation on the NTN serving cell based on the above-mentioned possible implementation methods. For the sake of brevity, these will not be elaborated here.

[0137] It should also be noted that for idle or inactive terminals, when the requirement to perform RRM measurement relaxation on the NTN serving cell and / or on neighboring cells of the NTN serving cell is met, the idle or inactive terminal does not directly initiate the execution of RRM measurement relaxation. As an example, and not a limitation, in one possible implementation, the idle or inactive terminal may first report to the base station, informing the base station that it needs to perform RRM measurement relaxation on the NTN serving cell and / or on neighboring cells of the NTN serving cell. Then, the base station may send a cell broadcast message or an RRC release message to the idle or inactive terminal to instruct it to perform RRM measurement relaxation on the NTN serving cell and / or on neighboring cells of the NTN serving cell.

[0138] In the embodiments of this application, for connected terminals, the measurement relaxation of RRM for the NTN serving cell and / or neighboring cells can include, but is not limited to, the following possible implementations:

[0139] In one possible implementation, the connected terminal can enable a longer measurement period (or evaluation period, or sampling interval) to measure the RRM of the NTN serving cell and / or neighboring cells. As an example, and not a limitation, if the service quality or received signal level of the NTN serving cell is higher than a third preset threshold, the measurement period for the RRM of the NTN serving cell and / or neighboring cells can be extended to a fixed value, such as 60s, 70s, 80s, 90s, ...

[0140] In another possible implementation, the connected terminal may not perform RRM measurements on the NTN serving cell and / or neighboring cells within a preset time period (e.g., 10 minutes, 30 minutes, 1 hour, 2 hours, etc.). That is, the connected terminal may stop performing RRM measurements on the NTN serving cell and / or neighboring cells within the preset time period.

[0141] In some other possible implementations, the connected terminal may not perform RRM measurements on the specified NTN serving cell and / or neighboring cells; or, the connected terminal may not perform RRM measurements on the specified frequency point; or, the connected terminal may not perform RRM measurements on the specified measurement object. The specified NTN serving cell and / or neighboring cells, the specified frequency point, and the specified measurement object may be indicated to the connected terminal by the base station in the RRC reconfiguration message.

[0142] It is understandable that, for a connected terminal, when the requirement to perform RRM measurement relaxation for the NTN serving cell and / or its neighboring cells is met, the connected terminal does not directly initiate the execution of RRM measurement relaxation. As an example, and not a limitation, in one possible implementation, the connected terminal may first report to the base station that it needs to perform RRM measurement relaxation for the NTN serving cell and / or its neighboring cells. Then, the base station may send an RRC reconfiguration message to the connected terminal to instruct it to perform RRM measurement relaxation for the NTN serving cell and / or its neighboring cells.

[0143] Based on the above technical solutions, in NTN, the measurement relaxation mechanism of RLM, BFD or RRM based on the reference position of the NTN cell to be measured can not only reduce the power consumption of the terminal, but also better adapt to the characteristic that the air interface signal quality under NTN is not significantly different between the cell center and the cell edge, and can more effectively measure RLM, BFD or RRM.

[0144] In one possible implementation, the terminal is in a connected state, the NTN cell to be measured includes the terminal's NTN serving cell and / or the neighboring cells of the NTN serving cell, and, based on the measurement relaxation standard, one or more of the following measurement relaxations are performed: RLM, BFD, or RRM, including: based on the measurement relaxation standard, performing one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or, performing measurement relaxations for the RRM of the neighboring cells.

[0145] In other words, when the terminal is in connected state, and provided the measurement relaxation criteria are met, the terminal can perform RLM, BFD, or RRM measurements on its NTN serving cell and / or the neighboring cells of the NTN serving cell. The following detailed description, in conjunction with implementations A to F, focuses on connected state terminals. In implementations A to F, the measurement relaxation criteria can be carried in the NTN cell broadcast message, or in the RRC proprietary message.

[0146] In one possible implementation A, the measurement relaxation criterion is further used to indicate a first distance threshold associated with the NTN serving cell; and the measurement relaxation based on the measurement relaxation criterion performs one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or performs measurement relaxation for the RRM of the neighboring cell, including: when the distance between the terminal and the NTN serving cell is less than or equal to the first distance threshold, performing one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or performs measurement relaxation for the RRM of the neighboring cell; wherein the distance between the terminal and the NTN serving cell is determined based on the reference location. This implementation can be applied to quasi-fixed cells.

[0147] Here, the first distance threshold is associated with the NTN serving cell. This can be understood as each NTN serving cell corresponding to a first distance threshold, and different NTN serving cells may have different first distance thresholds. Without loss of generality, the explanation of "the first distance threshold is associated with the NTN serving cell" in the following text is the same as here. When this content appears again in the following text, please refer to this section. For the sake of brevity, it will not be repeated here.

[0148] For a detailed description of the reference position, please refer to the relevant description of the reference position in step 310 above. For the sake of brevity, it will not be repeated here.

[0149] Example 1: The measurement relaxation standard can be used to indicate the reference location of the terminal's NTN serving cell and the first distance threshold Thresh1. In addition, the terminal can know its own location, so the terminal can calculate the distance Ml1 between the terminal and its NTN serving cell based on the reference location and its own location.

[0150] When the distance between the terminal and the serving NTN cell is less than or equal to the first distance threshold Thresh1, that is, when Ml1≤Thresh1 (for ease of description, this condition is referred to as condition 1), the terminal may perform one or more of the following measurement relaxations for the serving NTN cell: RLM, BFD, or RRM, and / or, the terminal may perform measurement relaxations for the RRM of the neighboring cell.

[0151] As an example rather than a limitation, in practical application scenarios, the first distance threshold can be 20 meters (m), 50m, 100m, 150m, 200m, ..., 1000m, ..., 2000m, ..., 3000m, ... etc.

[0152] The first distance threshold can be an integer between 0 and 65525, or an integer between 0 and 65535. Each step can represent 50m. For example, a first distance threshold of 1 is equivalent to a first distance threshold of 50m (obtained by multiplying 50m by 1); a first distance threshold of 5 is equivalent to a first distance threshold of 250m (obtained by multiplying 50m by 5); a first distance threshold of 10 is equivalent to a first distance threshold of 500m (obtained by multiplying 50m by 10); and so on. For simplicity, these details are not elaborated here. In practical applications, this application does not impose any restrictions on the specific value of the first distance threshold.

[0153] In one possible implementation B, the measurement relaxation criterion is further used to indicate a first distance threshold, the ephemeris information of the serving satellite, and the satellite epoch time, the first distance threshold and the serving satellite being associated with the NTN serving cell; and, based on the measurement relaxation criterion, performing one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or performing RRM measurement relaxation for the neighboring cell, including: when the distance between the terminal and the NTN serving cell is less than or equal to the first distance threshold, performing one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or performing RRM measurement relaxation for the neighboring cell; wherein the distance between the terminal and the NTN serving cell is determined based on the reference position, the satellite epoch time, and the ephemeris information. This implementation can be applied to Earth mobile cells.

[0154] The first distance threshold and the serving satellite associated with the NTN serving cell can be understood as follows: each NTN serving cell can correspond to a first distance threshold and a serving satellite, and different NTN serving cells can have different first distance thresholds and / or serving satellites. Without loss of generality, the explanation of "the first distance threshold and the serving satellite associated with the NTN serving cell" in the following text is the same as here. When this content appears again in the following text, please refer to this explanation. For the sake of brevity, it will not be repeated here.

[0155] Example 2: The measurement relaxation criterion can be used to indicate the reference position and first distance threshold Thresh1 of the terminal's NTN serving cell, as well as the ephemeris information and satellite epoch time of the serving satellite associated with the NTN serving cell. In this case, the terminal can determine the position of the NTN serving cell when the measurement relaxation criterion is acquired based on the indicated reference position of the terminal's NTN serving cell, the ephemeris information and satellite epoch time of the serving satellite associated with the NTN serving cell, and then calculate the distance Ml1 between the terminal and the terminal's NTN serving cell based on the determined position of the NTN serving cell and the terminal's position. If Ml1 ≤ Thresh1, the terminal can perform one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or, the terminal can perform measurement relaxation for the RRM of the neighboring cell.

[0156] For a detailed description of the reference position and the first distance threshold, please refer to the relevant description in Implementation Method A above. For the sake of brevity, it will not be repeated here.

[0157] Optionally, based on the above implementation methods A and B, the measurement relaxation criterion is also used to indicate the hysteresis location (or hysteresis parameter) (for ease of description, the hysteresis location is denoted as Hys in this application). When Ml1-Hys≤Thresh1 (for ease of description, this condition is denoted as condition 2), the terminal may perform measurement relaxation for one or more of the following for the serving NTN cell: RLM, BFD, or RRM, and / or, the terminal may perform measurement relaxation for the RRM of the neighboring cell.

[0158] As an example, not a limitation, the value of Hys can be 10m, 20m, 30m, 40m, 50m, ..., 100m, ..., 150m, 200m, ..., 1000m, ..., 2000m, ..., 3000m, ... etc. The value of Hys can also be an integer between 0 and 32768, where each step can represent 10m. For example, a Hys value of 1 is equivalent to Hys equaling 10m (derived from 10m × 1); a Hys value of 2 is equivalent to Hys equaling 20m (derived from 10m × 2); a Hys value of 10 is equivalent to Hys equaling 100m (derived from 10m × 10); and so on. For simplicity, these will not be elaborated further here. In practical applications, this application does not impose any limitations on the specific value of the lag position.

[0159] It is understood that in the above implementation methods A and B, if the distance between the terminal and the NTN serving cell is greater than the first distance threshold, the terminal may not perform one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or, the terminal may not perform measurement relaxations for the RRM of the neighboring cell.

[0160] In one possible implementation C, the reference location includes the reference location of the NTN serving cell and the reference location of at least one first neighboring cell, the first neighboring cell being any one of the neighboring cells of the NTN serving cell. The measurement relaxation parameter is further used to indicate a first distance threshold and at least one second distance threshold, the first distance threshold being associated with the NTN serving cell and the at least one second distance threshold being associated with at least one of the first neighboring cells. Furthermore, based on the measurement relaxation criterion, one or more of the following measurement relaxations are performed on the NTN serving cell: RLM, BFD, or RRM, and / or, measurement relaxations are performed on the neighboring cells. The measurement relaxation of the RRM of the cell includes: when the distance between the terminal and the NTN serving cell is less than or equal to the first distance threshold, and the distance between the terminal and the first neighboring cell is greater than or equal to the second distance threshold, performing one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or performing measurement relaxation of the RRM of the neighboring cell; wherein the distance between the terminal and the NTN serving cell is determined based on the reference location of the NTN serving cell, and the distance between the terminal and the first neighboring cell is determined based on the reference location of the first neighboring cell.

[0161] Here, the at least one second distance threshold is associated with at least one first neighboring cell. This can be understood as one first neighboring cell corresponding to one second distance threshold, and different first neighboring cells may correspond to different second distance thresholds. A detailed description of the second distance threshold can be found in the relevant description in Implementation Method A above; for brevity, it will not be repeated here. Without loss of generality, the explanation of "the at least one second distance threshold is associated with at least one first neighboring cell" in the following text is the same as here. When this content appears again in the following text, please refer to here; for brevity, it will not be repeated here.

[0162] Example 3: The measurement relaxation standard can be used to indicate the reference location of the terminal's NTN serving cell and a first distance threshold Thresh1, as well as the reference location of at least one first neighboring cell and a second distance threshold corresponding to the first neighboring cell. Thus, the terminal can calculate the distance Ml1 between itself and its NTN serving cell based on the reference location of the NTN serving cell and its own location, and the terminal can calculate the distance between itself and each first neighboring cell based on the reference location of each first neighboring cell and its own location.

[0163] Taking three first neighbor cells as an example, the distance between the first neighbor cell 1 and the terminal can be denoted as Ml2, and the second distance threshold corresponding to the first neighbor cell 1 is Thresh2; the distance between the first neighbor cell 2 and the terminal can be denoted as Ml3, and the second distance threshold corresponding to the first neighbor cell 2 is Thresh3; the distance between the first neighbor cell 3 and the terminal can be denoted as Ml4, and the second distance threshold corresponding to the first neighbor cell 3 is Thresh4.

[0164] In a possible implementation manner, when the following conditions are met, the terminal can perform measurement relaxation for one or more of the following for the NTN service cell: RLM, BFD or RRM, and / or perform measurement relaxation for RRM of the neighbor cell: Ml1 ≤ Thresh1, and, Ml2 ≥ Thresh2, Ml3 ≥ Thresh3, Ml4 ≥ Thresh4 (for ease of description, this condition is denoted as condition 3).

[0165] In another possible implementation manner, when the following conditions are met, the terminal can perform measurement relaxation for one or more of the following for the NTN service cell: RLM, BFD or RRM, and / or perform measurement relaxation for RRM of the neighbor cell: Ml1 ≤ Thresh1, and at least n (0 < n ≤ m, n and m are integers, and m is the number of first neighbor cells) in the first neighbor cells satisfy that the distance from the terminal is greater than or equal to the corresponding second distance threshold (for ease of description, this condition is denoted as condition 4). Optionally, in a possible implementation manner, the n can be configured by the base station for the terminal in cell broadcast or RRC dedicated signaling.

[0166] As an example, when n = 1, for example, when the following conditions are met, the terminal can perform measurement relaxation for one or more of the following for the NTN service cell: RLM, BFD or RRM, and / or perform measurement relaxation for RRM of the neighbor cell 1: Ml1 ≤ Thresh1, and, Ml2 ≥ Thresh2; for another example, when the following conditions are met, the terminal can perform measurement relaxation for one or more of the following for the NTN service cell: RLM, BFD or RRM, and / or perform measurement relaxation for RRM of the neighbor cell 2: Ml1 ≤ Thresh1, and, Ml3 ≥ Thresh3; for yet another example, when the following conditions are met, the terminal can perform measurement relaxation for one or more of the following for the NTN service cell: RLM, BFD or RRM, and / or perform measurement relaxation for RRM of the neighbor cell 3: Ml1 ≤ Thresh1, and, Ml4 ≥ Thresh4.

[0167] Alternatively, when n=1, for example, when Ml1≤Thresh1 and Ml2≥Thresh2, the terminal may perform one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or, perform measurement relaxations for the RRM of m neighboring cells, including neighboring cell 1; as another example, when Ml1≤Thresh1 and Ml3≥Thresh3, the terminal may perform one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or, perform measurement relaxations for the RRM of m neighboring cells, including neighboring cell 2; as yet another example, when Ml1≤Thresh1 and Ml4≥Thresh4, the terminal may perform one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or, perform measurement relaxations for the RRM of m neighboring cells, including neighboring cell 3.

[0168] Another example, when n=2, for instance, the terminal may perform one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or, perform measurement relaxations for the RRM of neighboring cell 1 and neighboring cell 2: Ml1≤Thresh1, and Ml2≥Thresh2, Ml3≥Thresh3; For another example, the terminal may perform one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, if the following conditions are met. RM, and / or, perform measurement relaxation of RRM for neighboring cell 2 and neighboring cell 3: Ml1≤Thresh1, and Ml3≥Thresh3, Ml4≥Thresh4; For example, the terminal may perform measurement relaxation of one or more of the following for the NTN serving cell if the following conditions are met: RLM, BFD or RRM, and / or, perform measurement relaxation of RRM for neighboring cell 1 and neighboring cell 3: Ml1≤Thresh1, and Ml2≥Thresh2, Ml4≥Thresh4.

[0169] Alternatively, when n=2, for example, when Ml1≤Thresh1, and Ml2≥Thresh2, Ml3≥Thresh3, the terminal may perform measurement relaxation of one or more of the following for the serving cell of the NTN: RLM, BFD, or RRM, and / or, perform measurement relaxation of RRM for m neighboring cells including neighboring cell 1 and neighboring cell 2; for example, when Ml1≤Thresh1, and Ml3≥Thresh3, Ml4≥Thresh4, the terminal may perform measurement relaxation of the NTN serving cell. The terminal may perform one or more of the following measurement relaxations for the TN serving cell: RLM, BFD, or RRM, and / or perform measurement relaxations for the RRM of m neighboring cells, including neighboring cell 2 and neighboring cell 3; for example, if Ml1≤Thresh1, and Ml2≥Thresh2, Ml4≥Thresh4, the terminal may perform one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or perform measurement relaxations for the RRM of m neighboring cells, including neighboring cell 1 and neighboring cell 3.

[0170] In another possible implementation, the terminal may perform one or more of the following measurement relaxations for the serving NTN cell: RLM, BFD, or RRM, and / or perform RRM measurement relaxation for the neighboring cell, provided that the following conditions are met: Ml1 ≤ Thresh1, and the target neighboring cell (one or more designated neighboring cells) in the first neighboring cell satisfies that the distance to the terminal is greater than or equal to the corresponding second distance threshold (for ease of description, this condition is referred to as condition 5). For example, if first neighboring cell 1 and first neighboring cell 2 are designated as target neighboring cells, that is, if Ml1 ≤ Thresh1, and Ml2 ≥ Thresh2, Ml3 ≥ Thresh3, the terminal may perform one or more of the following measurement relaxations for the serving NTN cell: RLM, BFD, or RRM, and / or perform RRM measurement relaxation for the neighboring cell.

[0171] In one possible implementation D, the reference location includes the reference location of the NTN serving cell and the reference location of at least one first neighboring cell, which is any one of the neighboring cells of the NTN serving cell; the measurement relaxation parameter is further used to indicate a first distance threshold, the ephemeris information and satellite epoch time of the serving satellite, and the ephemeris information of at least one neighboring satellite of the serving satellite and at least one second distance threshold, the first distance threshold being associated with the serving satellite and the at least one second distance threshold being associated with at least one of the first neighboring cells; and, based on the measurement relaxation criterion, performing one or more of the following measurement relaxations on the NTN serving cell: RLM, BFD, or RRM, and / or, performing The measurement relaxation of RRM for the neighboring cell includes: when the distance between the terminal and the NTN serving cell is less than or equal to the first distance threshold, and the distance between the terminal and the first neighboring cell is greater than or equal to the second distance threshold, performing one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or performing measurement relaxation of RRM for the neighboring cell; wherein the distance between the terminal and the NTN serving cell is determined based on the reference position of the NTN serving cell, the satellite epoch time, and the ephemeris information of the serving satellite, and the distance between the terminal and the first neighboring cell is determined based on the reference position of the first neighboring cell, the satellite epoch time, and the ephemeris information of the neighboring satellite.

[0172] Example 4: The measurement relaxation criterion can be used to indicate the reference location of the NTN serving cell of the terminal, the first distance threshold Thresh1, the reference location of at least one first neighboring cell and the second distance threshold corresponding to the first neighboring cell, as well as the ephemeris information and satellite epoch time of the serving satellite, and the ephemeris information of at least one neighboring satellite of the serving satellite. Therefore, the terminal can determine the location of the NTN serving cell when the measurement relaxation standard is acquired based on the reference location of the terminal's NTN serving cell, the ephemeris information of the serving satellite associated with the NTN serving cell, and the satellite epoch time. Then, based on the determined location of the NTN serving cell and the terminal's location, the distance Ml1 between the terminal and the terminal's NTN serving cell can be calculated. The terminal can also determine the location of each first neighboring cell when the measurement relaxation standard is acquired based on the reference location of each first neighboring cell, the ephemeris information of the serving satellite corresponding to each first neighboring cell (i.e., the neighboring satellite of the serving satellite corresponding to the terminal's serving cell). Then, based on the determined location of each first neighboring cell and the terminal's location, the distance between the terminal and each first neighboring cell can be calculated.

[0173] Taking three first neighboring cells as an example, the distance between the terminal and the first neighboring cell 1 can be denoted as Ml2, and the second distance threshold corresponding to the first neighboring cell 1 is Thresh2; the distance between the terminal and the first neighboring cell 2 can be denoted as Ml3, and the second distance threshold corresponding to the first neighboring cell 2 is Thresh3; the distance between the terminal and the first neighboring cell 3 can be denoted as Ml4, and the second distance threshold corresponding to the first neighboring cell 3 is Thresh4. When Ml1, Ml2, Ml3, and Ml4 meet certain conditions, the terminal can perform one or more of the following measurement relaxations for the serving cell of that NTN: RLM, BFD, or RRM, and / or, perform RRM measurement relaxation for that neighboring cell. For the conditions that Ml1, Ml2, Ml3, and Ml4 need to be met, please refer to the relevant descriptions of conditions 3 to 5 in Example 3 above; for brevity, they will not be repeated here.

[0174] Optionally, based on implementations C and D above, this measurement relaxation criterion is also used to indicate hysteresis location 1 (denoted as Hys1 for ease of description) and at least one hysteresis location 2. Each first neighboring cell can correspond to one hysteresis location 2. Detailed descriptions of hysteresis location 1 and hysteresis location 2 can be found in the relevant descriptions of hysteresis location Hys in implementations A and B above, and will not be repeated here for the sake of brevity.

[0175] Taking three first neighboring cells as an example, the lag position 2 corresponding to first neighboring cell 1 can be Hys2, the lag position 2 corresponding to first neighboring cell 2 can be Hys3, and the lag position 2 corresponding to first neighboring cell 3 can be Hys4.

[0176] In one possible implementation, the terminal may perform one or more of the following measurement relaxations for the serving cell of the NTN: RLM, BFD, or RRM, and / or perform measurement relaxations for the RRM of the neighboring cell, provided that the following conditions are met: Ml1 - Hys1 ≤ Thresh1, and Ml2 + Hys2 ≥ Thresh2 (or Ml2 - Hys2 ≥ Thresh2), Ml3 + Hys3 ≥ Thresh3 (or Ml3 - Hys3 ≥ Thresh3), Ml4 + Hys4 ≥ Thresh4 (or Ml4 - Hys4 ≥ Thresh4) (for ease of description, this condition is referred to as condition 6).

[0177] In another possible implementation, the terminal may perform one or more of the following measurement relaxations for the serving NTN cell: RLM, BFD, or RRM, and / or perform measurement relaxations for the RRM of the neighboring cell, provided that the following conditions are met: Ml1 - Hys1 ≤ Thresh1, and at least n (n is an integer greater than 0 and less than or equal to the number of the first neighboring cells) of the first neighboring cells satisfy a distance greater than or equal to the corresponding second distance threshold with respect to the terminal (for ease of description, this condition is referred to as condition 7).

[0178] In another possible implementation, the terminal may perform one or more of the following measurement relaxations for the serving NTN cell: RLM, BFD, or RRM, and / or perform measurement relaxations for the RRM of the neighboring cell, provided that the following conditions are met: Ml1 - Hys1 ≤ Thresh1, and the target neighboring cell (one or more designated neighboring cells) in the first neighboring cell satisfies that the distance to the terminal is greater than or equal to the corresponding second distance threshold (for ease of description, this condition is referred to as condition 8). For example, if the first neighboring cell 1 and the first neighboring cell 2 are designated as target neighboring cells, that is, if Ml1-Hys1≤Thresh1, and Ml2+Hys2≥Thresh2 (or Ml2-Hys2≥Thresh2), Ml3+Hys3≥Thresh3 (or Ml3-Hys3≥Thresh3), the terminal may perform one or more of the following measurement relaxations for the serving NTN cell: RLM, BFD, or RRM, and / or perform measurement relaxations for the RRM of the neighboring cell.

[0179] It is understood that in the above implementations C and D, if the distance between the terminal and the NTN serving cell is greater than the first distance threshold, or if the distance between the terminal and the first neighboring cell is less than the second distance threshold, the terminal may not perform one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or, the terminal may not perform RRM measurement relaxations for the neighboring cell.

[0180] In one possible implementation E, the measurement relaxation criterion is further used to indicate a distance change threshold and a duration threshold, which are associated with the NTN serving cell; and the measurement relaxation based on the measurement relaxation criterion is performed to apply one or more of the following to the NTN serving cell: RLM, BFD, or RRM, and / or to apply RRM to the neighboring cell, including: within the duration threshold, if the change in distance between the terminal and the NTN serving cell is less than or equal to the distance change threshold, performing one or more of the following measurement relaxations to the NTN serving cell: RLM, BFD, or RRM, and / or to apply RRM to the neighboring cell; wherein the distance between the terminal and the NTN serving cell is determined based on the reference location.

[0181] The distance change threshold and the duration threshold are associated with the NTN serving cell. This can be understood as each NTN serving cell corresponding to one distance change threshold and one duration threshold, and different NTN serving cells may have different distance change thresholds and / or duration thresholds. Without loss of generality, the explanation of "the distance change threshold and the duration threshold are associated with the NTN serving cell" in the following text is the same as here. When this content appears again in the following text, please refer to this explanation. For the sake of brevity, it will not be repeated here.

[0182] Example 5: This measurement relaxation criterion can be used to indicate the reference location, distance change threshold (location-delta-threshold), and duration threshold (T-threshold) of the terminal's NTN serving cell. The terminal can calculate the distance Ml1 between itself and its NTN serving cell based on the reference location and its own location. If Ml1 ≤ location-delta-threshold within the duration threshold (T-threshold) (for ease of description, this condition is referred to as condition 9), the terminal can perform measurement relaxation for one or more of the following for the NTN serving cell: RLM, BFD, or RRM, and / or, the terminal can perform measurement relaxation for the RRM of the neighboring cell.

[0183] In one possible implementation F, the measurement relaxation parameter is further used to indicate the ephemeris information, satellite epoch time, distance change threshold, and duration threshold of the serving satellite, the distance change threshold, and the duration threshold associated with the NTN serving cell; and, based on the measurement relaxation criterion, performing one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or performing measurement relaxation of the RRM of the neighboring cell, including: within the duration threshold, if the change in distance between the terminal and the NTN serving cell is less than or equal to the distance change threshold, performing one or more of the following measurement relaxations for the NTN serving cell: RLM, BFD, or RRM, and / or performing measurement relaxation of the RRM of the neighboring cell; wherein the distance between the terminal and the NTN serving cell is determined based on the reference position, the satellite epoch time, and the ephemeris information.

[0184] Example 6: The measurement relaxation criterion can be used to indicate the reference location of the terminal's NTN serving cell, the ephemeris information of the serving satellite, the satellite epoch time, the distance change threshold location-delta-threshold, and the duration threshold T-threshold. The terminal can determine the location of the NTN serving cell when the measurement relaxation criterion is acquired based on the reference location, the ephemeris information of the serving satellite, and the satellite epoch time. Then, based on the determined location of the NTN serving cell and the terminal's location, the distance Ml1 between the terminal and its NTN serving cell is calculated. Within the duration threshold T-threshold, if Ml1 – the reference distance value MlRef ≤ location-delta-threshold (for ease of description, this condition is denoted as condition 9), the terminal can perform measurement relaxation for one or more of the following for the NTN serving cell: RLM, BFD, or RRM, and / or, the terminal can perform measurement relaxation for the RRM of the neighboring cell.

[0185] In implementations E and F, the distance change threshold (location-delta-threshold) received by the terminal from the base station can be a fixed value. The value of this distance change threshold can be found in the description of the first distance threshold; for brevity, it will not be repeated here.

[0186] The reference distance value MlRef can change depending on the distance between the terminal and the NTN serving cell.

[0187] It is understood that the reference distance value MlRef is the reference distance between the terminal and the NTN serving cell at the current time (i.e., when the terminal acquires the measurement relaxation standard). In one possible implementation, the reference distance value MlRef can be set in a way that includes, but is not limited to, the following:

[0188] When a terminal switches from a previous NTN serving cell to the current NTN serving cell, the reference distance value MlRef can be assigned the current Ml1; or,

[0189] In subsequent measurements, if Ml1 > MlRef, the reference distance value MlRef can be updated to the larger current Ml1; or,

[0190] In subsequent measurements, if Ml1≤MlRef is satisfied, but the duration threshold T-threshold is not maintained, the reference distance value MlRef can be updated to the current Ml1.

[0191] In implementation methods E and F, the duration threshold T-threshold can take values ​​of 5s, 10s, 20s, 30s, 60s, 120s, 180s, 240s, 300s, ... In practical application scenarios, this application does not impose any restrictions on the specific value of the duration threshold T-threshold.

[0192] In implementations E and F, the base station can be configured with a first preset threshold, which is a distance change threshold (which can be a fixed value) received by the terminal from the base station. Within the duration threshold, if the distance between the terminal and the NTN serving cell is less than the first preset threshold, and the distance change between the terminal and the NTN serving cell is less than the distance change threshold, the terminal can be considered to have met the measurement relaxation state. Figure 4 This is a schematic diagram of entering and exiting the measurement relaxation state provided in this application.

[0193] For example, such as Figure 4 As shown, the terminal is within the duration threshold T threshold The internal judgment determines whether the change in distance between the terminal and the NTN serving cell is less than or equal to the distance change threshold L. threshold As shown in the figure, at the duration threshold T threshold Within this period, if the change in distance between the terminal and the NTN serving cell is less than or equal to the distance change threshold (location-delta-threshold), the terminal enters a measurement relaxation state starting from point P1 and continuously meets the measurement relaxation criteria between P1 and P2. After P2, the distance between the terminal and the NTN cell (MlRef) exceeds the distance change threshold (L). thresholdThat is, if the measurement relaxation criteria are not met after P2, the terminal can exit the measurement relaxation state starting from P2.

[0194] It is understood that in the above implementation methods E and F, if the change in distance between the terminal and the NTN serving cell is greater than the distance change threshold within the time limit, or if the time for which the change in distance between the terminal and the NTN serving cell is less than or equal to the distance change threshold does not last for the duration threshold, the terminal may not perform measurement relaxation of one or more of the following for the NTN serving cell: RLM, BFD, or RRM, and / or, the terminal may not perform measurement relaxation of RRM for the neighboring cell.

[0195] In the above implementation methods A to F, the detailed description of the terminal performing measurement relaxation of RLM, BFD or RRM of the NTN serving cell, or the detailed description of the terminal performing measurement relaxation of RRM of the neighboring cell, can be found in the relevant description of measurement relaxation of RLM, BFD or RRM of the NTN cell to be measured in step 320 above. For the sake of brevity, it will not be repeated here.

[0196] In one possible implementation, the terminal is in an idle or inactive state, the NTN cell to be measured includes the NTN serving cell where the terminal is located and / or the neighboring cells of the NTN serving cell, and, based on the measurement relaxation standard, measurement relaxation is performed on one or more of the following: RLM, BFD, or RRM, including: based on the measurement relaxation standard, performing measurement relaxation of the RRM of the neighboring cell, and / or performing measurement relaxation of the RRM of the NTN serving cell.

[0197] In other words, when the terminal is in an idle or inactive state, it can perform RRM measurements on neighboring cells of its NTN serving cell, provided that the measurement relaxation criteria are met. The following detailed explanation, using implementations A1 to F1, addresses idle or inactive terminals. In implementations A1 to F1, the measurement relaxation criteria can be included in the NTN cell broadcast message.

[0198] In one possible implementation A1, the measurement relaxation criterion is further used to indicate a third distance threshold associated with the NTN serving cell; and the measurement relaxation of the RRM of the neighboring cell and / or the RRM of the NTN serving cell, based on the measurement relaxation criterion, includes: performing measurement relaxation of the RRM of the neighboring cell and / or the RRM of the NTN serving cell when the distance between the terminal and the NTN serving cell is less than or equal to the third distance threshold; wherein the distance between the terminal and the NTN serving cell is determined based on the reference location. This implementation can be applied to quasi-fixed cells.

[0199] The third distance threshold is associated with the NTN serving cell. This can be understood as each NTN serving cell corresponding to a third distance threshold, and different NTN serving cells may have different third distance thresholds. Without loss of generality, the explanation of "the third distance threshold is associated with the NTN serving cell" in the following text is the same as here. When this content appears again in the following text, please refer to this section. For the sake of brevity, it will not be repeated here.

[0200] It is understandable that in practical applications, the value of the third distance threshold can be the same as or different from the value of the first distance threshold in implementations A to D. This application does not impose any restrictions on this. For a detailed description of the third distance threshold, please refer to the relevant description of the first distance threshold in implementation A above. For the sake of brevity, it will not be repeated here.

[0201] For a detailed description of the reference position, please refer to the relevant description of the reference position in step 310 above. For the sake of brevity, it will not be repeated here.

[0202] Example 7: The measurement relaxation standard can be used to indicate the reference location of the terminal's NTN serving cell and the third distance threshold Thresh5. In addition, the terminal can know its own location, so the terminal can calculate the distance Ml1 between the terminal and its NTN serving cell based on the reference location and its own location.

[0203] When the distance between the terminal and the serving NTN cell is less than or equal to the third distance threshold Thresh5, that is, when Ml1≤Thresh5 (for ease of description, this condition is referred to as condition 10), the terminal may perform measurement relaxation of RRM for the neighboring cell and / or perform measurement relaxation of RRM for the serving NTN cell.

[0204] In one possible implementation B1, the measurement relaxation criterion is further used to indicate a third distance threshold, the ephemeris information of the serving satellite, and the satellite epoch time, the third distance threshold and the serving satellite being associated with the NTN serving cell; and, based on the measurement relaxation criterion, performing measurement relaxation of the RRM of the neighboring cell, and / or performing measurement relaxation of the RRM of the NTN serving cell, includes: performing measurement relaxation of the RRM of the neighboring cell, and / or performing measurement relaxation of the RRM of the NTN serving cell, when the distance between the terminal and the NTN serving cell is less than or equal to the third distance threshold; wherein the distance between the terminal and the NTN serving cell is determined based on the reference position, the satellite epoch time, and the ephemeris information. This implementation can be applied to Earth-mobile cells.

[0205] The third distance threshold and the serving satellite are associated with the NTN serving cell. This can be understood as each NTN serving cell corresponding to one third distance threshold and one serving satellite. Different NTN serving cells may correspond to different third distance thresholds and / or serving satellites. Without loss of generality, the explanation of "the third distance threshold and the serving satellite are associated with the NTN serving cell" in the following text is the same as here. When this content appears again in the following text, please refer to this text. For the sake of brevity, it will not be repeated here.

[0206] Example 8: The measurement relaxation criterion can be used to indicate the reference position and third distance threshold Thresh5 of the terminal's NTN serving cell, as well as the ephemeris information and satellite epoch time of the serving satellite associated with the NTN serving cell. In this case, the terminal can determine the position of the NTN serving cell when the measurement relaxation criterion is acquired based on the indicated reference position of the terminal's NTN serving cell, the ephemeris information and satellite epoch time of the serving satellite associated with the NTN serving cell, and then calculate the distance Ml1 between the terminal and the terminal's NTN serving cell based on the determined position of the NTN serving cell and the terminal's position. If Ml1 ≤ Thresh5, the terminal can perform measurement relaxation of the RRM of the neighboring cell, and / or perform measurement relaxation of the RRM of the NTN serving cell.

[0207] For a detailed description of the reference position and the third distance threshold, please refer to the relevant description in implementation method A1 above. For the sake of brevity, it will not be repeated here.

[0208] Optionally, based on implementation methods A1 and B1 described above, this measurement relaxation criterion is also used to indicate the hysteresis position Hys. When Ml1 - Hys ≤ Thresh5 (for ease of description, this condition is denoted as Condition 11), the terminal can perform measurement relaxation of the RRM for the neighboring cell, and / or, perform measurement relaxation of the RRM for the NTN serving cell. A description of the hysteresis position Hys can be found in the relevant descriptions in implementation methods A and B above; for brevity, it will not be repeated here.

[0209] It is understandable that in the above implementation methods A1 and B1, if the distance between the terminal and the NTN serving cell is greater than the first distance threshold, the terminal may not perform the measurement relaxation of RRM for the NTN serving cell and / or neighboring cells.

[0210] In one possible implementation C1, the reference location includes a reference location of the NTN serving cell and a reference location of at least one first neighboring cell, the first neighboring cell being any one of the neighboring cells of the NTN serving cell; the measurement relaxation parameter is further used to indicate a third distance threshold and at least one fourth distance threshold, the third distance threshold being associated with the NTN serving cell and the at least one fourth distance threshold being associated with at least one of the first neighboring cells; and the measurement relaxation of the RRM of the neighboring cell and / or the measurement relaxation of the RRM of the NTN serving cell based on the measurement relaxation criterion includes: performing measurement relaxation of the RRM of the neighboring cell and / or the measurement relaxation of the RRM of the NTN serving cell when the distance between the terminal and the NTN serving cell is less than or equal to the third distance threshold and when the distance between the terminal and the first neighboring cell is greater than or equal to the fourth distance threshold; wherein the distance between the terminal and the NTN serving cell is determined based on the reference location of the NTN serving cell and the distance between the terminal and the first neighboring cell is determined based on the reference location of the first neighboring cell.

[0211] Here, the at least one fourth distance threshold is associated with at least one first neighboring cell. This can be understood as one fourth distance threshold corresponding to one first neighboring cell, and different first neighboring cells may correspond to different fourth distance thresholds. A detailed description of the fourth distance threshold can be found in the relevant description in Implementation Method A above; for brevity, it will not be repeated here. Without loss of generality, the explanation of "the at least one fourth distance threshold is associated with at least one first neighboring cell" in the following text is the same as here. When this content appears again in the following text, please refer to here; for brevity, it will not be repeated here.

[0212] Example 9: The measurement relaxation standard can be used to indicate the reference location of the terminal's NTN serving cell and the third distance threshold Thresh5, as well as the reference location of at least one first neighboring cell and the fourth distance threshold corresponding to the first neighboring cell. Thus, the terminal can calculate the distance Ml1 between the terminal and its NTN serving cell based on the reference location of the NTN serving cell and the terminal's own location, and the terminal can calculate the distance between each first neighboring cell and the terminal based on the reference location of each first neighboring cell and the terminal's own location.

[0213] Taking three first neighboring cells as an example, the distance between the terminal and the first neighboring cell 1 can be denoted as Ml2, and the fourth distance threshold corresponding to the first neighboring cell 1 is Thresh6; the distance between the terminal and the first neighboring cell 2 can be denoted as Ml3, and the fourth distance threshold corresponding to the first neighboring cell 2 is Thresh7; the distance between the terminal and the first neighboring cell 3 can be denoted as Ml4, and the fourth distance threshold corresponding to the first neighboring cell 3 is Thresh8.

[0214] In one possible implementation, the terminal may perform measurement relaxation of the RRM of the neighboring cell and / or measurement relaxation of the RRM of the serving cell of the NTN, provided that the following conditions are met: Ml1≤Thresh5, and Ml2≥Thresh6, Ml3≥Thresh7, Ml4≥Thresh8 (for ease of description, this condition is referred to as condition 12).

[0215] In another possible implementation, the terminal may perform measurement relaxation of the RRM of the neighboring cell and / or measurement relaxation of the RRM of the serving NTN cell, provided that the following conditions are met: Ml1≤Thresh5, and at least n (n is an integer greater than 0 and less than or equal to the number of the first neighboring cells) of the first neighboring cells satisfy that the distance to the terminal is greater than or equal to the corresponding fourth distance threshold (for ease of description, this condition is referred to as condition 13).

[0216] In another possible implementation, the terminal may perform measurement relaxation of the RRM of the neighboring cell and / or the RRM of the serving NTN cell, provided that the following conditions are met: Ml1 ≤ Thresh5, and the target neighboring cell (one or more designated neighboring cells) in the first neighboring cell has a distance from the terminal greater than or equal to the corresponding fourth distance threshold (for ease of description, this condition is referred to as condition 14). For example, if first neighboring cell 1 and first neighboring cell 2 are designated as target neighboring cells, that is, if Ml1 ≤ Thresh5, and Ml2 ≥ Thresh6, Ml3 ≥ Thresh7, the terminal may perform measurement relaxation of the RRM of the neighboring cell and / or the RRM of the serving NTN cell.

[0217] In one possible implementation D1, the reference location includes the reference location of the NTN serving cell and the reference location of at least one first neighboring cell, which is any one of the neighboring cells of the NTN serving cell; the measurement relaxation parameter is further used to indicate a third distance threshold, the ephemeris information and satellite epoch time of the serving satellite, and the ephemeris information of at least one neighboring satellite of the serving satellite and at least one fourth distance threshold, the third distance threshold being associated with the serving satellite and the NTN serving cell, and the at least one fourth distance threshold being associated with at least one of the first neighboring cells; and, based on the measurement relaxation criterion, the measurement relaxation of the RRM of the neighboring cell is performed, and / or, the measurement relaxation of the NTN is performed. The measurement relaxation of RRM for the TN serving cell includes: performing measurement relaxation of RRM for the neighboring cell when the distance between the terminal and the NTN serving cell is less than or equal to the third distance threshold, and the distance between the terminal and the first neighboring cell is greater than or equal to the fourth distance threshold, and / or performing measurement relaxation of RRM for the NTN serving cell; wherein the distance between the terminal and the NTN serving cell is determined based on the reference position of the NTN serving cell, the satellite epoch time, and the ephemeris information of the serving satellite, and the distance between the terminal and the first neighboring cell is determined based on the reference position of the first neighboring cell, the satellite epoch time, and the ephemeris information of the neighboring satellite.

[0218] Example 10: The measurement relaxation criterion can be used to indicate the reference location of the NTN serving cell of the terminal, the third distance threshold Thresh5, the reference location of at least one first neighboring cell and the fourth distance threshold corresponding to the first neighboring cell, as well as the ephemeris information and satellite epoch time of the serving satellite, and the ephemeris information of at least one neighboring satellite of the serving satellite. Therefore, the terminal can determine the location of the NTN serving cell when the measurement relaxation standard is acquired based on the reference location of the terminal's NTN serving cell, the ephemeris information of the serving satellite associated with the NTN serving cell, and the satellite epoch time. Then, based on the determined location of the NTN serving cell and the terminal's location, the distance Ml1 between the terminal and the terminal's NTN serving cell can be calculated. The terminal can also determine the location of each first neighboring cell when the measurement relaxation standard is acquired based on the reference location of each first neighboring cell, the ephemeris information of the serving satellite corresponding to each first neighboring cell (i.e., the neighboring satellite of the serving satellite corresponding to the terminal's serving cell). Then, based on the determined location of each first neighboring cell and the terminal's location, the distance between the terminal and each first neighboring cell can be calculated.

[0219] Taking three first neighboring cells as an example, the distance between the terminal and the first neighboring cell 1 can be denoted as Ml2, and the fourth distance threshold corresponding to the first neighboring cell 1 is Thresh6; the distance between the terminal and the first neighboring cell 2 can be denoted as Ml3, and the fourth distance threshold corresponding to the first neighboring cell 2 is Thresh7; the distance between the terminal and the first neighboring cell 3 can be denoted as Ml4, and the fourth distance threshold corresponding to the first neighboring cell 3 is Thresh8. When Ml1, Ml2, Ml3, and Ml4 meet the conditions, the terminal can perform measurement relaxation of the RRM of the neighboring cell, and / or perform measurement relaxation of the RRM of the NTN serving cell. The conditions that Ml1, Ml2, Ml3, and Ml4 need to be met can be found in the descriptions of conditions 12 to 14 in Example 9 above; for brevity, they will not be repeated here.

[0220] Optionally, based on the above implementations C1 and D1, this measurement relaxation criterion is also used to indicate hysteresis location 1 (denoted as Hys1 for ease of description) and at least one hysteresis location 2. Each first neighboring cell can correspond to one hysteresis location 2. Detailed descriptions of hysteresis location 1 and hysteresis location 2 can be found in the relevant descriptions of hysteresis location Hys in implementations A and B above, and will not be repeated here for the sake of brevity.

[0221] Taking three first neighboring cells as an example, the lag position 2 corresponding to first neighboring cell 1 can be Hys2, the lag position 2 corresponding to first neighboring cell 2 can be Hys3, and the lag position 2 corresponding to first neighboring cell 3 can be Hys4.

[0222] In one possible implementation, the terminal may perform measurement relaxation of the RRM of the neighboring cell and / or the RRM of the serving cell of the NTN, provided that the following conditions are met: Ml1-Hys1≤Thresh5, and Ml2+Hys2≥Thresh6 (or Ml2-Hys2≥Thresh6), Ml3+Hys3≥Thresh7 (or Ml3-Hys3≥Thresh7), Ml4+Hys4≥Thresh8 (or Ml4-Hys4≥Thresh8) (for ease of description, this condition is referred to as condition 15).

[0223] In another possible implementation, the terminal may perform measurement relaxation of the RRM of the neighboring cell and / or the RRM of the serving NTN cell, provided that the following conditions are met: Ml1-Hys1≤Thresh5, and at least n (n is an integer greater than 0 and less than or equal to the number of the first neighboring cells) of the first neighboring cells satisfy that the distance to the terminal is greater than or equal to the corresponding fourth distance threshold (for ease of description, this condition is referred to as condition 16).

[0224] In another possible implementation, the terminal may perform measurement relaxation of the RRM of the neighboring cell and / or the RRM of the serving NTN cell, provided that the following conditions are met: Ml1 - Hys1 ≤ Thresh5, and the target neighboring cell (one or more designated neighboring cells) in the first neighboring cell satisfies that the distance to the terminal is greater than or equal to the corresponding fourth distance threshold (for ease of description, this condition is referred to as condition seventeen). For example, if the first neighboring cell 1 and the first neighboring cell 2 are designated as target neighboring cells, that is, if Ml1 - Hys1 ≤ Thresh5, and Ml2 + Hys2 ≥ Thresh6 (or Ml2 - Hys2 ≥ Thresh6), Ml3 + Hys3 ≥ Thresh7 (or Ml3 - Hys3 ≥ Thresh7), the terminal may perform measurement relaxation of the RRM of the neighboring cell and / or the RRM of the serving NTN cell.

[0225] It is understood that in the above implementations C1 and D1, if the distance between the terminal and the NTN serving cell is greater than the first distance threshold, or if the distance between the terminal and the first neighboring cell is less than the second distance threshold, the terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0226] In one possible implementation E1, the measurement relaxation criterion is further used to indicate a distance change threshold and a duration threshold, which are associated with the NTN serving cell; and the measurement relaxation of the RRM of the neighboring cell and / or the RRM of the NTN serving cell based on the measurement relaxation criterion includes: within the duration threshold, if the change in the distance between the terminal and the NTN serving cell is less than or equal to the distance change threshold, performing measurement relaxation of the RRM of the neighboring cell and / or performing measurement relaxation of the RRM of the NTN serving cell; wherein the distance between the terminal and the NTN serving cell is determined based on the reference location.

[0227] Example 11: The measurement relaxation criterion can be used to indicate the reference location, distance change threshold (location-delta-threshold), and duration threshold (T-threshold) of the terminal's NTN serving cell. The terminal can calculate the distance Ml1 between itself and its NTN serving cell based on the reference location and its own location. If Ml1 ≤ location-delta-threshold within the duration threshold (T-threshold) (for ease of description, this condition is referred to as condition 9), the terminal can perform measurement relaxation of the RRM of the neighboring cell and / or perform measurement relaxation of the RRM of the NTN serving cell.

[0228] In one possible implementation F1, the measurement relaxation parameter is further used to indicate the ephemeris information, satellite epoch time, distance change threshold, and duration threshold of the serving satellite, the serving satellite, the distance change threshold, and the duration threshold are associated with the NTN serving cell; and, based on the measurement relaxation criterion, the measurement relaxation of the RRM of the neighboring cell, and / or the measurement relaxation of the RRM of the NTN serving cell, includes: within the duration threshold, if the change in the distance between the terminal and the NTN serving cell is less than or equal to the distance change threshold, performing the measurement relaxation of the RRM of the neighboring cell, and / or performing the measurement relaxation of the RRM of the NTN serving cell; wherein the distance between the terminal and the NTN serving cell is determined based on the reference position, the satellite epoch time, and the ephemeris information.

[0229] Example 12: This measurement relaxation criterion can be used to indicate the reference location of the terminal's NTN serving cell, the ephemeris information of the serving satellite, the satellite epoch time, the distance change threshold (location-delta-threshold), and the duration threshold (T-threshold). The terminal can determine the location of the NTN serving cell when the measurement relaxation criterion is acquired based on the reference location, the ephemeris information of the serving satellite, and the satellite epoch time. Then, based on the determined location of the NTN serving cell and the terminal's location, the distance Ml1 between the terminal and its NTN serving cell is calculated. Within the duration threshold T-threshold, if Ml1 - reference distance value MlRef ≤ location-delta-threshold (for ease of description, this condition is denoted as condition 9), the terminal can perform measurement relaxation of the RRM of the neighboring cell, and / or perform measurement relaxation of the RRM of the NTN serving cell.

[0230] In implementations E1 and F1, the distance change threshold (location-delta-threshold) received by the terminal from the base station can be a fixed value. The value of this distance change threshold can be found in the description of the first distance threshold value; for brevity, it will not be repeated here.

[0231] The reference distance value MlRef can change depending on the distance between the terminal and the NTN serving cell. A detailed description of the reference distance value MlRef can be found in Example Six above; for brevity, it will not be repeated here.

[0232] It is understood that in the above implementation methods E1 and F1, if the change in distance between the terminal and the NTN serving cell is greater than the distance change threshold within the time limit, or if the time for which the change in distance between the terminal and the NTN serving cell is less than or equal to the distance change threshold does not last for the duration threshold, the terminal may not perform the measurement relaxation of RRM for the NTN serving cell and / or neighboring cells.

[0233] For a detailed description of the duration threshold T-threshold in implementation methods E1 and F1, please refer to the relevant descriptions in implementation methods E and F above. For the sake of brevity, it will not be repeated here.

[0234] In the above implementation methods A1 to F1, the detailed description of the terminal performing measurement relaxation of the RRM of the neighboring cell and / or performing measurement relaxation of the RRM of the NTN serving cell can be found in step 320 above regarding the relevant description of measurement relaxation of the RRM of the NTN serving cell and the neighboring cell. For the sake of brevity, it will not be repeated here.

[0235] For ease of description, conditions 1 to 16 above can be collectively referred to as location conditions in this application. In some possible implementations, the base station can include the above location conditions in the measurement relaxation criteria and instruct the terminal. In other possible implementations, the above location conditions can be directly deployed on the terminal, and when the base station indicates the corresponding reference position and threshold, the terminal can determine whether to perform measurement relaxation based on the reference position and threshold indicated by the base station and the location conditions deployed on the terminal.

[0236] Optionally, the measurement relaxation criterion is also used to indicate first-time information, which indicates the time at which the measurement relaxation is performed.

[0237] In other words, the measurement relaxation standard can be used to indicate the content indicated in any of the above-described implementations A to F and A1 to F1, and can also be used to indicate first time information, which can be used to indicate when the terminal performs measurement relaxation of RLM, BFD or RRM.

[0238] In one possible implementation, the first time information includes: a first time point, which is used to indicate that a measurement of relaxation was performed prior to that first time point.

[0239] Example 13: The measurement relaxation criterion can also be used to indicate the first time point t1-Threshold. Under the aforementioned positional conditions, and before this first time point t1-Threshold, the terminal can perform measurement relaxation on RLM, BFD, or RRM. That is, under the aforementioned positional conditions, the terminal can perform measurement relaxation on RLM, BFD, or RRM before the first time point t1-Threshold, and after the first time point t1-Threshold, the terminal can choose not to perform measurement relaxation on RLM, BFD, or RRM. Specifically, the time Mt during which the terminal performs measurement relaxation on RLM, BFD, or RRM satisfies: Mt ≤ t1-Threshold (for ease of description, this condition is denoted as Condition 17).

[0240] In practical applications, the value of the first time point t1-Threshold can be Coordinated Universal Time (UTC). For example, the value of the first time point t1-Threshold can be an integer between 0 and 549755813887, where each step can represent 10ms. For instance, if the value of the first time point t1-Threshold is 1, it is equivalent to the first distance threshold being 10ms (obtained by 10ms × 1); if the value of the first time point t1-Threshold is 5, it is equivalent to the first distance threshold being 50ms (obtained by 10ms × 5); if the value of the first time point t1-Threshold is 10, it is equivalent to the first distance threshold being 100ms (obtained by 10ms × 10), and so on. For the sake of simplicity, these will not be elaborated further here. In practical applications, this application does not impose any restrictions on the specific value of the first time point.

[0241] It is understandable that the first time point t1-Threshold is earlier than the time T-service when the serving satellite associated with the NTN serving cell ceases service. For example, if the service time of serving satellite 1 to region 1 is 8:00-10:00 (24-hour system), then the first time point t1-Threshold can be any time point between 8:00-10:00 that is earlier than the service end time of 10:00.

[0242] In another possible implementation, the first time information includes a first duration and a second time point, the first duration and the second time point being used to indicate that a measurement of relaxation is performed within the first duration starting from the second time point.

[0243] Example 14: The measurement relaxation criterion can also be used to indicate the first duration T-Duration and the second time point t2-Threshold. Under the aforementioned location conditions, the terminal can perform measurement relaxation of RLM, BFD, or RRM during the period from the second time point t2-Threshold to t2-Threshold+T-Duration; however, before the second time point t2-Threshold, or after t2-Threshold+T-Duration, the terminal may not perform measurement relaxation of RLM, BFD, or RRM. That is, the time Mt during which the terminal performs measurement relaxation of RLM, BFD, or RRM satisfies: 2-Threshold ≤ Mt ≤ t2-Threshold+T-Duration (for ease of description, this condition is referred to as Condition 18).

[0244] It is understood that condition 18 above can be transformed into Mt∈[t2-Threshold,t2-Threshold+T-Duration], and this application does not limit it in this way.

[0245] It is also understandable that t2-Threshold+T-Duration is earlier than the time T-service when the serving satellite associated with the NTN serving cell ceases service. For example, if the service time of serving satellite 1 to region 1 is 8:00-10:00 (24-hour system), then t2-Threshold+T-Duration can be a point in time between 8:00-10:00 that is earlier than the service end time of 10:00.

[0246] In another possible implementation, the first time information includes a third time point and a fourth time point, the third time point being earlier than the fourth time point, the third time point and the fourth time point being used to indicate that a measurement of relaxation is performed between the third time point and the fourth time point.

[0247] Example 15: The measurement relaxation criterion can also be used to indicate the third time point t3-Threshold and the fourth time point t4-Threshold. The terminal can relax the measurement of RLM, BFD, or RRM between the third time point t3-Threshold and the fourth time point t4-Threshold, provided the above location conditions are met. That is, the time Mt during which the terminal performs the measurement relaxation of RLM, BFD, or RRM satisfies: Mt∈[t3-Threshold, t4-Threshold] (for ease of description, this condition is denoted as Condition 19).

[0248] It is understood that condition 19 above can be transformed into t3-Threshold≤Mt≤t4-Threshold, and this application does not limit it in this way.

[0249] It is also understandable that the fourth time point t4-Threshold is earlier than the service end time T-service of the serving satellite associated with the NTN serving cell. For example, if the service time of serving satellite 1 to region 1 is 8:00-10:00 (24-hour system), then the fourth time point t4-Threshold can be any time point between 8:00-10:00 that is earlier than the service end time of 10:00.

[0250] For ease of description, conditions 17 to 19 above can be collectively referred to as time conditions. In some possible implementations, the base station can include the above time conditions in the measurement relaxation criteria and instruct the terminal. In other possible implementations, the above time conditions can be directly deployed on the terminal, and the terminal can determine whether to perform measurement relaxation and at what time to perform measurement relaxation based on the reference position, threshold, first time information indicated by the base station, and the time conditions deployed on the terminal.

[0251] In Examples 13 to 15 above, the detailed description of the terminal performing measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, or the detailed description of the terminal performing measurement relaxation of RRM for the neighboring cell, and / or the detailed description of performing measurement relaxation of RRM for the NTN serving cell can be found in step 320 above regarding the relevant description of measurement relaxation of RRM for the NTN serving cell and neighboring cells. For the sake of brevity, it will not be repeated here.

[0252] By combining real-time information, the terminal can determine whether the measurement relaxation criteria are met within a specific time period based on its time with satellite service, and determine the time period within which measurement relaxation should be performed. This not only reduces the terminal's power consumption, but also avoids starting the judgment on whether the measurement relaxation criteria are met from the start time of satellite service to the terminal, thus improving the effectiveness of measurement relaxation.

[0253] Optionally, the measurement relaxation criterion is further used to indicate first parameter information and / or second parameter information; wherein the first parameter information is used to assess whether the serving cell where the terminal is located meets the good cell service quality criterion or the non-cell edge criterion, and the second parameter information is used to assess whether the terminal meets the low mobility criterion; and the measurement relaxation based on the measurement relaxation criterion includes performing measurement relaxation on one or more of the following: RLM, BFD, or RRM.

[0254] Example 16: The measurement relaxation criterion is also used to indicate the first parameter information. That is, the measurement relaxation criterion can be used to indicate the reference position, the aforementioned position-related thresholds and / or the aforementioned position conditions, and can also be used to indicate the first parameter information. Based on the aforementioned position conditions and the first parameter information, the terminal can determine whether to perform measurement relaxation on RLM, BFD, or RRM.

[0255] In one possible implementation, for a connected terminal, the connected terminal can determine whether the location conditions and the good cell service quality criteria are met. If both the location conditions and the good cell service quality criteria are met, the connected terminal can perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal can perform measurement relaxation of RRM for the neighboring cells of the NTN serving cell. If only the location conditions are met, or only the good cell service quality criteria are met, or neither the location conditions nor the good cell service quality criteria are met, the terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0256] For idle or inactive terminals, the idle or inactive terminal can determine whether the location conditions and non-cell edge criteria are met. If both the location conditions and the non-cell edge criteria are met, the idle or inactive terminal can perform measurement relaxation of RRM for the NTN serving cell and / or neighboring cells. If only the location conditions are met, or only the non-cell edge criteria are met, or neither the location conditions nor the good cell service quality criteria are met, the idle or inactive terminal may not perform measurement relaxation of RRM for the NTN serving cell and / or neighboring cells.

[0257] In another possible implementation, for the connected terminal, the connected terminal initiates an evaluation based on the first parameter information to determine whether the good cell service quality standard is met only if the location conditions described above are met. If both the location conditions and the good cell service quality standard are met, the connected terminal may perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal may perform measurement relaxation of RRM for the neighboring cells of the NTN serving cell. If only the location conditions are met, or only the good cell service quality standard is met, or neither the location conditions nor the good cell service quality standard are met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0258] For idle or inactive terminals, the idle or inactive terminal will only initiate an assessment based on the first parameter information to determine whether it meets the non-cell edge criterion if the location conditions are met. If both the location conditions and the non-cell edge criterion are met, the idle or inactive terminal may perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells. If only the location conditions are met, or only the good cell service quality criterion is met, or neither the location conditions nor the non-cell edge criterion are met, the idle or inactive terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0259] Example 17: The measurement relaxation criterion can be used to indicate the reference position, the aforementioned position-related threshold and / or the aforementioned position conditions, as well as the aforementioned first time information and / or the aforementioned time conditions, and can also be used to indicate the first parameter information. Furthermore, the terminal can determine whether to perform measurement relaxation on RLM, BFD, or RRM based on this information.

[0260] In one possible implementation, for a connected terminal, the connected terminal can determine whether location conditions, time conditions, and good cell service quality criteria are met. If all three are met, the connected terminal can perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal can perform measurement relaxation of RRM for the neighboring cells of the NTN serving cell. If at least one of the three is not met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0261] For idle or inactive terminals, the idle or inactive terminal can determine whether the location condition, time condition, and non-cell edge criterion are met. If all three conditions are met, the idle or inactive terminal can perform measurement relaxation of RRM for the NTN serving cell and / or neighboring cells. If at least one of the three conditions is not met, the idle or inactive terminal may not perform measurement relaxation of RRM for the NTN serving cell and / or neighboring cells.

[0262] In another possible implementation, for the connected terminal, the determination of whether the above location conditions are met, and the evaluation of whether the good cell service quality standard is met based on the first parameter information, only occur when the above time conditions are satisfied. If all three conditions are met, the connected terminal can perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal can perform measurement relaxation of RRM for the neighboring cells of the NTN serving cell; if at least one of the three conditions is not met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0263] For idle or inactive terminals, the terminal will only initiate the determination of whether the location conditions are met, and the assessment of whether the non-cell edge criterion is met based on the first parameter information, provided that the aforementioned time conditions are satisfied. If all three conditions are met, the idle or inactive terminal can perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells; if at least one of the three conditions is not met, the idle or inactive terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0264] In another possible implementation, for the connected terminal, the assessment based on the first parameter information to determine whether the good cell service quality standard is met only occurs if the aforementioned location and time conditions are satisfied. If all three conditions are met, the connected terminal may perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal may perform measurement relaxation of RRM for neighboring cells of the NTN serving cell; if at least one of the three conditions is not met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0265] For idle or inactive terminals, the terminal will only initiate an assessment based on the first parameter information to determine whether it meets the non-cell edge criterion if the aforementioned location and time conditions are met. If all three conditions are met, the idle or inactive terminal can perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells; if at least one of the three conditions is not met, the idle or inactive terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0266] In another possible implementation, for a connected terminal, the determination of whether the aforementioned time conditions are met only begins if the location conditions and the good cell service quality standard are satisfied. If all three conditions are met, the connected terminal may perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal may perform measurement relaxation of RRM for neighboring cells of the NTN serving cell; if at least one of the three conditions is not met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0267] For idle or inactive terminals, the aforementioned location conditions and non-cell edge criteria must be met before the terminal initiates the process of checking whether the aforementioned time conditions are met. If all three conditions are met, the idle or inactive terminal can perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells; if at least one of the three conditions is not met, the idle or inactive terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0268] In another possible implementation, for a connected terminal, the determination of whether the above-mentioned location conditions are met only begins if the aforementioned time conditions and good cell service quality criteria are satisfied. If all three conditions are met, the connected terminal may perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal may perform measurement relaxation of RRM for neighboring cells of the NTN serving cell; if at least one of the three conditions is not met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0269] For idle or inactive terminals, the terminal will only initiate the process of checking whether the above location conditions are met if the aforementioned time conditions and non-cell edge criteria are satisfied. If all three conditions are met, the idle or inactive terminal can perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells; if at least one of the three conditions is not met, the idle or inactive terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0270] Example 18: The measurement relaxation criterion is also used to indicate the second parameter information. That is, the measurement relaxation criterion can be used to indicate the reference position, the aforementioned position-related thresholds and / or the aforementioned position conditions, and can also be used to indicate the second parameter information. Based on the aforementioned position conditions and the second parameter information, the terminal can determine whether to perform measurement relaxation for RLM, BFD, or RRM.

[0271] In one possible implementation, for a connected terminal, the connected terminal can determine whether the location conditions and the low mobility criterion are met. If both the location conditions and the low mobility criterion are met, the connected terminal can perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal can perform measurement relaxation of RRM for the neighboring cells of the NTN serving cell. If only the location conditions are met, or only the low mobility criterion is met, or neither the location conditions nor the low mobility criterion are met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0272] For idle or inactive terminals, the idle or inactive terminal can determine whether the location conditions and low mobility criteria are met. If both the location conditions and the low mobility criteria are met, the idle or inactive terminal can perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells. If only the location conditions are met, or only the low mobility criteria are met, or neither the location conditions nor the low mobility criteria are met, the idle or inactive terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0273] In another possible implementation, for a connected terminal, the connected terminal initiates an evaluation based on the second parameter information to determine whether the low mobility criterion is met only if the location conditions described above are met. If both the location conditions and the low mobility criterion are met, the connected terminal may perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal may perform measurement relaxation of RRM for neighboring cells of the NTN serving cell. If only the location conditions are met, or only the low mobility criterion is met, or neither the location conditions nor the low mobility criterion is met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0274] For idle or inactive terminals, the idle or inactive terminal will only initiate an assessment based on the second parameter information to determine whether it meets the low mobility criterion if the location conditions described above are met. If both the location conditions and the low mobility criterion are met, the idle or inactive terminal may perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells. If only the location conditions are met, or only the low mobility criterion is met, or neither the location conditions nor the low mobility criterion are met, the idle or inactive terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0275] Example 19: The measurement relaxation criterion can be used to indicate the reference position, the aforementioned position-related threshold and / or the aforementioned position conditions, as well as the aforementioned first time information and / or the aforementioned time conditions, and can also be used to indicate the second parameter information. Furthermore, the terminal can determine whether to perform measurement relaxation on RLM, BFD, or RRM based on this information.

[0276] In one possible implementation, for a connected terminal, the connected terminal can determine whether location conditions, time conditions, and low mobility criteria are met. If all three are met, the connected terminal can perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal can perform measurement relaxation of RRM for neighboring cells of the NTN serving cell. If at least one of the three is not met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0277] For idle or inactive terminals, the idle or inactive terminal can determine whether the location condition, time condition, and low mobility criterion are met. If all three are met, the idle or inactive terminal can perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells. If at least one of the three is not met, the connected terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0278] In another possible implementation, for the connected terminal, the determination of whether the location condition is met and the evaluation of whether the low mobility criterion is met are initiated only if the aforementioned time condition is satisfied. If all three conditions are met, the connected terminal may perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal may perform measurement relaxation of RRM for neighboring cells of the NTN serving cell; if at least one of the three conditions is not met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0279] For idle or inactive terminals, the terminal will only initiate the determination of whether the location conditions are met, and the assessment of whether the low mobility criterion is met based on the second parameter information, provided that the aforementioned time conditions are satisfied.

[0283] For idle or inactive terminals, the aforementioned location conditions and low mobility conditions must be met before the idle or inactive terminal can initiate the process of checking whether the aforementioned time conditions are met. If all three conditions are met, the idle or inactive terminal can perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells; if at least one of the three conditions is not met, the idle or inactive terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0284] In another possible implementation, for a connected terminal, the determination of whether the aforementioned location conditions are met only occurs if the aforementioned time conditions and low mobility criteria are satisfied. If all three conditions are met, the connected terminal may perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal may perform measurement relaxation of RRM for neighboring cells of the NTN serving cell; if at least one of the three conditions is not met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0295] Example 21: The measurement relaxation criterion can be used to indicate the reference position, the aforementioned position-related threshold and / or the aforementioned position conditions, as well as the aforementioned first time information and / or time conditions. It can also be used to indicate the first parameter information and the second parameter information. Based on this information, the terminal can determine whether to perform measurement relaxation on RLM, BFD, or RRM.

[0296] In one possible implementation, for a connected terminal, the connected terminal can determine whether location conditions, time conditions, good cell service quality criteria, and low mobility criteria are met. If all four are met, the connected terminal can perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal can perform measurement relaxation of RRM for neighboring cells of the NTN serving cell. If at least one of the four is not met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0309] For idle or inactive terminals, the terminal only initiates an assessment based on the second parameter information to determine whether the low mobility criterion is met, and whether the location condition is met, provided that the aforementioned time conditions and non-cell edge criteria are satisfied. If all four conditions are met, the idle or inactive terminal can perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells; if at least one of the four conditions is not met, the idle or inactive terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0310] In another possible implementation, for the connected terminal, only after the aforementioned time conditions and low mobility criteria are met will the connected terminal initiate an assessment based on the first parameter information to determine whether the good cell service quality criteria are met, and whether the aforementioned location conditions are met.

[0311] For idle or inactive terminals, the terminal only initiates an assessment based on the first parameter information to determine whether it meets the non-cell edge criterion and the location condition, provided that the aforementioned time conditions and low mobility criteria are met. If all four conditions are met, the idle or inactive terminal can perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells; if at least one of the four conditions is not met, the idle or inactive terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0312] In another possible implementation, for a connected terminal, the assessment of whether the low mobility criterion is met based on the second parameter information only occurs if the aforementioned location conditions, time conditions, and good cell service quality criteria are satisfied.

[0313] For idle or inactive terminals, the low mobility criterion is only assessed based on the second parameter information if the aforementioned location conditions, time conditions, and non-cell edge criteria are met. If all four conditions are met, the idle or inactive terminal can perform measurement relaxation of neighboring cells and / or RRM for the NTN serving cell; if at least one of the four conditions is not met, the idle or inactive terminal may not perform measurement relaxation of RRM for the NTN serving cell and / or neighboring cells.

[0314] In another possible implementation, for a connected terminal, the assessment of whether the good cell service quality standard is met based on the first parameter information only occurs if the aforementioned location conditions, time conditions, and low mobility criteria are satisfied. If all four conditions are met, the connected terminal may perform measurement relaxation of RLM, BFD, or RRM for the NTN serving cell, and / or, the connected terminal may perform measurement relaxation of RRM for neighboring cells of the NTN serving cell; if at least one of the four conditions is not met, the connected terminal may not perform measurement relaxation of RLM, BFD, or RRM.

[0315] For idle or inactive terminals, the assessment based on the first parameter information to determine whether the non-cell edge criterion is met only occurs if the aforementioned location conditions, time conditions, and low mobility criteria are satisfied. If all four conditions are met, the idle or inactive terminal can perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells; if at least one of the four conditions is not met, the idle or inactive terminal may not perform RRM measurement relaxation for the NTN serving cell and / or neighboring cells.

[0316] Optionally, the terminal reports one or more of the following measurement relaxation states: RLM, BFD, or RRM.

[0317] Measuring relaxation state can be understood as whether the relaxation criteria are met.

[0318] As an example and not a limitation, the terminal can report the measurement relaxation state to the base station through the first auxiliary information; that is, the measurement relaxation state can be carried in the first auxiliary information.

[0319] As an example and not a limitation, 1 can be used to indicate that the measurement relaxation criteria are met, or that the measurement relaxation state is in effect, or that measurement relaxation is being performed; and 0 can be used to indicate that the measurement relaxation criteria are not met, or that the measurement relaxation state is not in effect, or that measurement relaxation is not being performed. This application does not limit this. Alternatively, the terminal can report a Boolean variable to the base station, where "true" indicates that measurement relaxation needs to be performed, and "false" indicates that measurement relaxation is not performed.

[0320] For example, for RLM, the terminal reports to the base station that the value of the Boolean variable for the NTN serving cell is "true" to inform the base station that the terminal needs to perform RLM measurement relaxation for the NTN serving cell; the terminal reports to the base station that the value of the Boolean variable for the NTN serving cell is "false" to inform the base station that the terminal does not perform RLM measurement relaxation for the NTN serving cell.

[0321] For example, for BFD, the terminal reports to the base station that the value of the Boolean variable for the NTN serving cell is "true" to inform the base station that the terminal needs to perform BFD measurement relaxation for the NTN serving cell; the terminal reports to the base station that the value of the Boolean variable for the NTN serving cell is "false" to inform the base station that the terminal does not perform BFD measurement relaxation for the NTN serving cell.

[0322] For example, for RRM, the terminal reports a Boolean variable value of "true" to the base station to inform the base station that the terminal needs to perform RRM measurement relaxation or RRM measurement relaxation conditions; the terminal reports a Boolean variable value of "false" to the base station to inform the base station that the terminal does not perform RRM measurement relaxation or does not meet RRM measurement relaxation conditions.

[0323] In one possible implementation, the terminal may first report to the base station that measurement relaxation needs to be performed, and if the conditions are not met, then report that measurement relaxation does not need to be performed (or exited). This application does not impose any limitations on this implementation.

[0324] For example, when the terminal is a connected terminal, if the terminal meets the measurement relaxation criteria, or in other words, if the terminal meets the conditions for performing measurement relaxation on RLM, BFD, or RRM, the terminal may report to the base station that it meets the measurement relaxation criteria; if the terminal does not meet the measurement relaxation criteria, or in other words, if the terminal does not meet the conditions for performing measurement relaxation on RLM, BFD, or RRM, the terminal may report to the base station that it does not meet the measurement relaxation criteria, or the terminal may choose not to report whether it meets the measurement relaxation criteria. For ease of description, this content is referred to as the reporting condition in this application. In one possible implementation, the reporting condition can be directly deployed on the terminal. In another possible implementation, the base station indicates the reporting condition to the terminal. This application does not limit this aspect.

[0325] Optionally, the measurement relaxation criterion, in addition to indicating one or more of the aforementioned reference position, position-related threshold, position conditions, first time information, time conditions, first parameter information, and second parameter information, can also be used to indicate under what circumstances the terminal performs measurement relaxation for RLM, BFD, or RRM, and / or whether the terminal needs to report the measurement relaxation status to the base station. If the base station instructs the terminal to report the measurement relaxation status, the terminal can report to the base station whether it needs to perform or not perform (or exit) measurement relaxation for RLM, BFD, or RRM. If the base station does not instruct the terminal to report the measurement relaxation status, the terminal can report the measurement relaxation status or not. In this case, whether to report the measurement relaxation status depends on the terminal's own configuration information. That is, if the terminal is configured to report the measurement relaxation status, then the terminal can report the measurement relaxation status to the base station; if the terminal is configured not to report the measurement relaxation status, or if the terminal is not configured to report the measurement relaxation status, then the terminal can not report the measurement relaxation status.

[0326] For example, the base station can instruct the terminal through measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first-time information, and that the terminal can perform measurement relaxation for RLM, BFD, or RRM if both location and time conditions are met. Furthermore, the terminal needs to report the measurement relaxation status to the base station. In other words, if both location and time conditions are met simultaneously, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it needs to perform measurement relaxation for RLM, BFD, or RRM; if only the location condition or only the time condition is met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it has not performed (or withdrawn) measurement relaxation for RLM, BFD, or RRM.

[0327] For example, the base station can instruct the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first-time information, and that the terminal can perform measurement relaxation for RLM, BFD, or RRM if either the location condition or the time condition is met (i.e., not necessarily both the location and time conditions must be met simultaneously). The terminal also needs to report the measurement relaxation status to the base station. In other words, if only the location condition is met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it needs to perform measurement relaxation for RLM, BFD, or RRM; if only the time condition is met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it needs to perform measurement relaxation for RLM, BFD, or RRM. If neither the location nor the time condition is met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it has not performed (or withdrawn) measurement relaxation for RLM, BFD, or RRM.

[0328] For example, the base station can instruct the terminal through measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first-time information, and that, provided the location conditions are met (i.e., it is not necessary to meet both location and time conditions simultaneously; that is, the location condition is a necessary condition, while the time condition is not), the terminal can perform measurement relaxation for RLM, BFD, or RRM, and the terminal needs to report the measurement relaxation status to the base station. In other words, if only the location conditions are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it needs to perform measurement relaxation for RLM, BFD, or RRM; if only the time conditions are met, or if neither the location nor the time conditions are met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it has not performed (or withdrawn) measurement relaxation for RLM, BFD, or RRM. For example, the base station can instruct the terminal through measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first-time information, and, provided that the time condition is met (i.e., it is not necessary to meet both the location and time conditions simultaneously; that is, the time condition is a necessary condition, while the location condition is not), the terminal can perform measurement relaxation for RLM, BFD, or RRM, and the terminal needs to report the measurement relaxation status to the base station. In other words, if only the time condition is met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it needs to perform measurement relaxation for RLM, BFD, or RRM; if only the location condition is met, or if neither the location nor the time condition is met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it has not performed (or withdrawn) measurement relaxation for RLM, BFD, or RRM.

[0329] For example, the base station can instruct the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, and first parameter information; and that the terminal can perform measurement relaxation for RLM, BFD, or RRM if the location conditions, good cell service quality criteria, or non-cell edge criteria are met. Alternatively, the terminal may only initiate an evaluation based on the first parameter information to determine whether the good cell service quality criteria or non-cell edge criteria are met if the aforementioned location conditions are met, and the terminal can perform measurement relaxation for RLM, BFD, or RRM if the location conditions, good cell service quality criteria, or non-cell edge criteria are met. In other words, the terminal does not perform measurement relaxation for RLM, BFD, or RRM if only the location conditions, or only the good cell service quality criteria or non-cell edge criteria are met. In this example, the base station does not instruct the terminal whether it needs to report the measurement relaxation status to the base station; the terminal can report the measurement relaxation status or not, depending on its own configuration.

[0330] For example, the base station can instruct the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first parameter information, and, provided that the location conditions are met, or that the good cell service quality criteria or non-cell edge criteria are met (it is not necessary to meet both the location conditions and the good cell service quality criteria or non-cell edge criteria simultaneously), the terminal can perform measurement relaxation for RLM, BFD, or RRM, and the terminal needs to report the measurement relaxation status to the base station. In other words, if only the location conditions are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that the terminal needs to perform measurement relaxation for RLM, BFD, or RRM; if only the good cell service quality criteria or non-cell edge criteria are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that the terminal needs to perform measurement relaxation for RLM, BFD, or RRM. If the location conditions, good cell service quality standards, or non-cell edge standards are not met, the terminal may choose not to perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it has not performed (or withdrawn) measurement relaxation for RLM, BFD, or RRM.

[0331] For example, the base station can instruct the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first parameter information, and, provided that the location conditions are met (i.e., it is not necessary to simultaneously meet the location conditions and the good cell service quality standard or the non-cell edge standard; that is, the location conditions are necessary, while the good cell service quality standard or the non-cell edge standard are not necessary), the terminal can perform measurement relaxation for RLM, BFD, or RRM, and the terminal needs to report the measurement relaxation status to the base station. In other words, if only the location conditions are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that the terminal needs to perform measurement relaxation for RLM, BFD, or RRM; if only the good cell service quality standard or the non-cell edge standard is met, or if neither the location conditions nor the good cell service quality standard or the non-cell edge standard is met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it has not performed (or withdrawn) measurement relaxation for RLM, BFD, or RRM.

[0332] For example, the base station can instruct the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first parameter information, and, provided that the good cell service quality criterion or non-cell edge criterion is met (i.e., it is not necessary to simultaneously meet both the location condition and the good cell service quality criterion or non-cell edge criterion; that is, the good cell service quality criterion or non-cell edge criterion is a necessary condition, while the location condition is not a necessary condition), the terminal can perform measurement relaxation for RLM, BFD, or RRM, and the terminal needs to report the measurement relaxation status to the base station. In other words, if only the good cell service quality criterion or non-cell edge criterion is met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that the terminal needs to perform measurement relaxation for RLM, BFD, or RRM; if only the location condition is met, or if neither the location condition nor the good cell service quality criterion or non-cell edge criterion is met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it has not performed (or withdrawn) measurement relaxation for RLM, BFD, or RRM.

[0333] For example, the base station can instruct the terminal through measurement relaxation criteria: the aforementioned reference location, location-related thresholds, and second parameter information; and that, if the location conditions and low mobility criteria are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM, and the terminal needs to report the measurement relaxation status to the base station; or, if the aforementioned location conditions are met, the terminal will initiate an assessment based on the second parameter information to determine whether the low mobility criteria are met, and if the location conditions and low mobility criteria are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM, and the terminal needs to report the measurement relaxation status to the base station. In other words, if both the location conditions and the low mobility criteria are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that measurement relaxation for RLM, BFD, or RRM is required; if only the location conditions or only the low mobility criteria are met, the terminal will not perform measurement relaxation for RLM, BFD, or RRM and will report that it has not performed (or withdrawn) measurement relaxation for RLM, BFD, or RRM.

[0334] For example, the base station can instruct the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, second parameter information, and that the terminal can perform measurement relaxation for RLM, BFD, or RRM if the location condition or the low mobility criterion is met (not necessarily both). In other words, the terminal can perform measurement relaxation for RLM, BFD, or RRM if only the location condition is met; it can also perform measurement relaxation for RLM, BFD, or RRM if only the low mobility criterion is met. If neither the location condition nor the low mobility criterion is met, the terminal may not perform measurement relaxation for RLM, BFD, or RRM. In this example, the base station does not instruct the terminal whether it needs to report the measurement relaxation status to the base station; therefore, the terminal may or may not report the measurement relaxation status, depending on its own configuration.

[0335] For example, the base station can instruct the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, second parameter information, and, provided that the location conditions are met (i.e., it is not necessary to simultaneously meet both the location conditions and the low mobility criterion; that is, the location conditions are a necessary condition, while the low mobility criterion is not), the terminal can perform measurement relaxation for RLM, BFD, or RRM, and the terminal needs to report the measurement relaxation status to the base station. In other words, if only the location conditions are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it needs to perform measurement relaxation for RLM, BFD, or RRM; if only the low mobility criterion is met, or if neither the location conditions nor the low mobility criterion are met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it has not performed (or withdrawn) measurement relaxation for RLM, BFD, or RRM.

[0336] For example, the base station can indicate to the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, second parameter information, and, provided that the low mobility criterion is met (i.e., it is not necessary to simultaneously meet both the location condition and the low mobility criterion; that is, the low mobility criterion is a necessary condition, while the location condition is not), that the terminal can perform measurement relaxation for RLM, BFD, or RRM, and the terminal needs to report the measurement relaxation status to the base station. In other words, if only the low mobility criterion is met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that the terminal needs to perform measurement relaxation for RLM, BFD, or RRM; if only the location condition is met, or if neither the location condition nor the low mobility criterion is met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM and report to the base station that it has not performed (or withdrawn) measurement relaxation for RLM, BFD, or RRM.

[0337] For example, the base station can instruct the terminal through measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first parameter information, and second parameter information; and, if the location conditions, good cell service quality criteria or non-cell edge criteria, and low mobility criteria are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM; and the terminal needs to report the measurement relaxation status to the base station. That is, if the location conditions, good cell service quality criteria or non-cell edge criteria, and low mobility criteria are all met simultaneously, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that measurement relaxation for RLM, BFD, or RRM is required; if at least one of these three criteria is not met, the terminal will not perform measurement relaxation for RLM, BFD, or RRM and will report that it has not performed (or withdrawn) measurement relaxation for RLM, BFD, or RRM.

[0338] For example, the base station can instruct the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first parameter information, and second parameter information. Furthermore, the terminal can perform measurement relaxation for RLM, BFD, or RRM if the location conditions are met (i.e., the location conditions are necessary, while the Good Cell Service Quality (GSS) standard, Non-Cell Edge (NOC) standard, and Low Mobility (LRM) standard are not necessary). In other words, as long as the location conditions are met, regardless of whether the GSS standard, NOC standard, or LRM standard is met, the terminal can perform measurement relaxation for RLM, NOC, or RRM; however, if the location conditions are not met, regardless of whether the GSS standard, NOC standard, or LRM standard is met, the terminal may not perform measurement relaxation for RLM, NOC, or RRM. In this example, the base station does not instruct the terminal whether it needs to report the measurement relaxation status to the base station; therefore, the terminal may or may not report the measurement relaxation status, depending on its own configuration.

[0339] For example, the base station can instruct the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first parameter information, and second parameter information. Furthermore, if the location conditions and low mobility criteria are met (i.e., location conditions and low mobility criteria are necessary conditions, while good cell service quality criteria or non-cell edge criteria are not necessary conditions), the terminal can perform measurement relaxation for RLM, BFD, or RRM. In other words, as long as both location conditions and low mobility criteria are met simultaneously, regardless of whether the good cell service quality criteria or non-cell edge criteria are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM; if the location conditions are not met, or the low mobility criteria are not met, regardless of whether the good cell service quality criteria or non-cell edge criteria are met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM. In this example, the base station does not instruct the terminal whether it needs to report the measurement relaxation status to the base station; therefore, the terminal can report the measurement relaxation status or not, depending on its own configuration.

[0340] For example, the base station can instruct the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first time information, first parameter information, and second parameter information. Furthermore, the terminal will only initiate an assessment based on the first parameter information to determine whether it meets the Good Cell Service Quality (GSS) or Non-Cell Edge (NOC) criteria, and based on the second parameter information to determine whether it meets the Low Mobility (LRM) criteria, provided that both location and time conditions are met. The terminal can only perform measurement relaxation for RLM, BFD, or RRM if the location, time, GSS, NOC, and LRM criteria are all met. In other words, the terminal can only perform measurement relaxation for RLM, BFD, or RRM if all four criteria are simultaneously met; if at least one of these criteria is not met, the terminal can choose not to perform (or exit) measurement relaxation for RLM, BFD, or RRM. In this example, the base station does not instruct the terminal whether it needs to report the measurement relaxation status to the base station; therefore, the terminal can report the measurement relaxation status or not, depending on its own configuration.

[0341] For example, the base station can instruct the terminal via measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first time information, first parameter information, and second parameter information. Furthermore, if the location conditions are met (i.e., the location conditions are necessary, while the Good Cell Service Quality (GSS) or Non-Cell Edge (NOC) standard, Low Mobility (LMC) standard, and time conditions are not necessary), the terminal can perform measurement relaxation for RLM, BFD, or RRM. In other words, as long as the location conditions are met, regardless of whether the time conditions, GSS or NOC standard, and LMC standard are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM; however, if the location conditions are not met, regardless of whether the time conditions, GSS or NOC standard, and LMC standard are met, the terminal may not perform measurement relaxation for RLM, BFD, or RRM. In this example, the base station does not instruct the terminal whether it needs to report the measurement relaxation status to the base station; therefore, the terminal may or may not report the measurement relaxation status, depending on its own configuration.

[0342] For example, the base station can instruct the terminal through measurement relaxation criteria: the aforementioned reference location, location-related thresholds, first time information, first parameter information, and second parameter information. Furthermore, if the location and time conditions are met (i.e., the location and time conditions are necessary, while the Good Cell Service Quality Standard, Non-Cell Edge Standard, and Low Mobility Standard are not necessary), the terminal can perform measurement relaxation for RLM, BFD, or RRM. The terminal also needs to report the measurement relaxation status to the base station. In other words, as long as both the location and time conditions are met, regardless of whether the Good Cell Service Quality Standard, Non-Cell Edge Standard, and Low Mobility Standard are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM and report to the base station that measurement relaxation for RLM, BFD, or RRM is required. However, if the location or time conditions are not met, regardless of whether the Good Cell Service Quality Standard, Non-Cell Edge Standard, and Low Mobility Standard are met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM and report that it has not performed (or withdrawn from) measurement relaxation for RLM, BFD, or RRM.

[0343] For the sake of brevity, examples will not be provided here.

[0344] Optionally, when the terminal is in a connected state, the base station can instruct the terminal to report a measurement result. If the terminal reports to the base station that it meets the measurement relaxation criteria and initiates measurement relaxation for RLM, BFD, or RRM, the terminal starts the measurement result reporting timer. During the timer's execution, the terminal can perform measurement relaxation for RLM, BFD, or RRM but does not report the measurement result to the base station. After the timer expires, the terminal can report the measurement result to the base station.

[0345] Optionally, for idle or inactive terminals, the result of whether the measurement relaxation criteria are met may not be reported before normal communication with the base station is restored. When normal communication with the base station is required to be restored, the result of whether the measurement relaxation criteria are met may be reported to the base station.

[0346] For example, for an idle-state terminal, the idle-state terminal can report to the base station whether the measurement relaxation criteria for RRM are met in the RRC Setup Complete message or UE Assistance Information. Alternatively, the idle-state terminal can report to the base station in the RRC Setup Complete message that the terminal has saved an availability indication for measurement relaxation. After security activation, the base station can request the terminal to report whether the measurement relaxation criteria for RRM are met. After sending the transmission security mode command (i.e., before the base station receives the security mode completion message from the terminal), the base station can immediately send a request to the terminal to report whether the measurement relaxation criteria for RRM are met.

[0347] For example, for an inactive terminal, the base station can request the terminal to provide measurement relaxation criteria for RRM in the RRC Resume message, and the inactive terminal can report whether the measurement relaxation criteria for RRM are met in the RRC Resume Complete message. Alternatively, the inactive terminal can provide the base station with an indication that the terminal has saved the availability of measurement relaxation in the RRC Resume Complete message, and then the base station can request the terminal to report whether the measurement relaxation criteria for RRM are met.

[0348] Based on the above technical solutions, firstly, in NTN, the measurement relaxation mechanism for RLM, BFD, or RRM based on the reference location of the NTN cell to be measured not only reduces the terminal's power consumption but also better adapts to the characteristic that the air interface signal quality in NTN does not differ significantly between the cell center and cell edge, enabling more effective RLM, BFD, or RRM measurements. Secondly, by combining first-time information, the terminal can determine whether the measurement relaxation criteria are met within a specific time period based on its time with satellite service and determine the time period for performing measurement relaxation. This not only reduces the terminal's power consumption but also avoids starting the judgment on whether the measurement relaxation criteria are met from the start time of satellite service to the terminal, thus improving the effectiveness of measurement relaxation. Furthermore, by combining good cell service quality criteria or non-cell edge criteria, and / or low mobility criteria, the terminal can not only reduce its power consumption but also improve the effectiveness of measurement relaxation.

[0349] Figure 5 This is a schematic flowchart of another method for measuring relaxation in NTN provided in the embodiments of this application.

[0350] like Figure 5 The method 500 shown may include steps 510 and 520. This method 500 can be executed by a communication device, which may be a terminal, a component configured in the terminal (such as a chip, chip system, etc.), or a logic module or software capable of implementing all or part of the terminal's functions; this application does not limit this. The following uses a terminal as an example to describe each step of this method 500 in detail.

[0351] In step 510, the terminal acquires a measurement relaxation standard, which is used to indicate first time information, which is used to indicate the time for performing measurement relaxation.

[0352] This first-time information is associated with the NTN cell to be measured. It can be understood that each NTN cell to be measured corresponds to a first-time information, and the reference location of different NTN cells to be measured can be different.

[0353] The terminal acquiring measurement relaxation criteria can be understood as the terminal receiving all or part of the measurement relaxation criteria from other devices (such as base stations), and some measurement relaxation criteria can be configured on the terminal.

[0354] For example, the measurement relaxation standard can be carried in an NTN cell broadcast message, and the terminal can receive the NTN cell broadcast message to obtain the measurement relaxation standard. Alternatively, the measurement relaxation standard can be carried in an RRC proprietary message, and the terminal can receive the RRC proprietary message to obtain the measurement relaxation standard.

[0355] For example, a base station or NTN cell can send a measurement relaxation standard carrying the aforementioned first-time information to a terminal via an NTN cell broadcast message or an RRC proprietary message. Accordingly, the terminal can receive the measurement relaxation standard from the base station via the NTN cell.

[0356] In step 520, the terminal performs measurement relaxation on one or more of the following based on the measurement relaxation criteria: RLM, BFD, or RRM.

[0357] After obtaining the measurement relaxation standard, the terminal can perform one or more of the measurement relaxations of RLM, BFD, or RRM of the NTN cell to be measured based on the measurement relaxation standard.

[0358] For a detailed description of the measurement relaxation of RLM, BFD, or RRM performed by the terminal, please refer to the relevant description of the measurement relaxation of RLM, BFD, or RRM of the NTN cell to be measured in step 320 of method 300 above. For the sake of brevity, it will not be repeated here.

[0359] Optionally, the first time information includes: a first time point, which is used to indicate that the measurement relaxation was performed before the first time point.

[0360] As an example, this measurement relaxation criterion can be used to indicate a first time point t1-Threshold before which the terminal can perform measurement relaxation on RLM, BFD, or RRM. That is, the terminal can perform measurement relaxation on RLM, BFD, or RRM before the first time point t1-Threshold, but after the first time point t1-Threshold, the terminal can choose not to perform measurement relaxation on RLM, BFD, or RRM. Specifically, the time Mt during which the terminal performs measurement relaxation on RLM, BFD, or RRM satisfies: Mt ≤ t1-Threshold (for ease of description, this condition is denoted as Condition 17).

[0361] In practical applications, as an example rather than a limitation, the value of the first time point t1-Threshold can be Coordinated Universal Time (UTC). A detailed description of the possible values ​​for the first time point can be found in Example Thirteen above, and for the sake of brevity, it will not be repeated here. In practical applications, this application does not impose any limitations on the specific value of the first time point.

[0362] It is understandable that the first time point t1-Threshold is earlier than the time T-service when the serving satellite associated with the NTN serving cell ceases service. For example, if the service time of serving satellite 1 to region 1 is 8:00-10:00 (24-hour system), then the first time point t1-Threshold can be any time point between 8:00-10:00 that is earlier than the service end time of 10:00.

[0363] Optionally, the first time information includes: a first duration and a second time point, the first duration and the second time point being used to indicate that a measurement of relaxation is performed within the first duration starting from the second time point.

[0364] As an example, this measurement relaxation criterion can be used to indicate a first duration T-Duration and a second time point t2-Threshold. The terminal can perform measurement relaxation on RLM, BFD, or RRM during the period from the second time point t2-Threshold to t2-Threshold+T-Duration; however, before the second time point t2-Threshold, or after t2-Threshold+T-Duration, the terminal may not perform measurement relaxation on RLM, BFD, or RRM. That is, the time Mt during which the terminal performs measurement relaxation on RLM, BFD, or RRM satisfies: 2-Threshold ≤ Mt ≤ t2-Threshold+T-Duration (for ease of description, this condition is referred to as Condition 18).

[0365] It is understood that condition 18 above can be transformed into Mt∈[t2-Threshold,t2-Threshold+T-Duration], and this application does not limit it in this way.

[0366] It is also understandable that t2-Threshold+T-Duration is earlier than the time T-service when the serving satellite associated with the NTN serving cell ceases service. For example, if the service time of serving satellite 1 to region 1 is 8:00-10:00 (24-hour system), then t2-Threshold+T-Duration can be a point in time between 8:00-10:00 that is earlier than the service end time of 10:00.

[0367] Optionally, the first time information includes a third time point and a fourth time point, the third time point being earlier than the fourth time point, the third time point and the fourth time point being used to indicate that a measurement relaxation was performed between the third time point and the fourth time point.

[0368] As an example, this measurement relaxation criterion can be used to indicate the third time point t3-Threshold and the fourth time point t4-Threshold, during which the terminal can relax the measurement of RLM, BFD, or RRM between the third time point t3-Threshold and the fourth time point t4-Threshold. That is, the time Mt during which the terminal performs measurement relaxation of RLM, BFD, or RRM satisfies: Mt∈[t3-Threshold, t4-Threshold] (for ease of description, this condition is denoted as condition 19).

[0369] It is understood that condition 19 above can be transformed into t3-Threshold≤Mt≤t4-Threshold, and this application does not limit it in this way.

[0370] It is also understandable that the fourth time point t4-Threshold is earlier than the service end time T-service of the serving satellite associated with the NTN serving cell. For example, if the service time of serving satellite 1 to region 1 is 8:00-10:00 (24-hour system), then the fourth time point t4-Threshold can be any time point between 8:00-10:00 that is earlier than the service end time of 10:00.

[0371] For ease of description, conditions 17 to 19 above can be collectively referred to as time conditions. In some possible implementations, the base station can include the above time conditions in the measurement relaxation criteria and instruct the terminal. In other possible implementations, the above time conditions can be directly deployed on the terminal, and the terminal can determine whether to perform measurement relaxation and at what time to perform measurement relaxation based on the reference position, threshold, first time information indicated by the base station, and the time conditions deployed on the terminal.

[0372] By using real-time information, the terminal can determine whether the measurement relaxation criteria are met within a specific time period based on its time with the satellite service, and determine the time period within which to perform measurement relaxation. This not only reduces the terminal's power consumption, but also avoids starting the judgment on whether the measurement relaxation criteria are met from the start time of the satellite service to the terminal, thereby improving the effectiveness of measurement relaxation.

[0373] In one possible implementation, the measurement relaxation criterion may also indicate one or more of the aforementioned reference position, position-related threshold, position conditions, time conditions, first parameter information, and / or second parameter information.

[0374] In other words, the terminal can determine whether the conditions for performing the measurement relaxation for RLM, BFD, or RRM are met based on one or more of the reference position, position-related threshold, position conditions, first time information, time conditions, first parameter information, and second parameter information configured by the base station to the terminal.

[0375] For example, the base station can use this measurement relaxation standard to indicate first-time information to the terminal, as well as the reference location and location-related thresholds.

[0376] For a detailed explanation of the reference position and the position-related thresholds, please refer to the relevant explanation in Method 300 above. For the sake of brevity, it will not be repeated here.

[0377] In one possible implementation, the terminal can determine whether the time condition is met based on the first time information, and whether the position condition is met based on the reference position and the position-related threshold; if both the time condition and the position condition are met, the terminal can perform measurement relaxation on RLM, BFD, or RRM; if only the time condition is met, or only the position condition is met, or neither the time condition nor the position condition is met, the terminal can choose not to perform measurement relaxation on RLM, BFD, or RRM.

[0378] In another possible implementation, the terminal can first determine whether the time condition is met based on the first time information. If the time condition is met, the terminal will then initiate a determination of whether the position condition is met based on the parameter position and the position-related threshold. If both the time condition and the position condition are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM. If only the time condition is met, or only the position condition is met, or neither the time condition nor the position condition is met, the terminal may not perform measurement relaxation for RLM, BFD, or RRM.

[0379] For example, the base station can use this measurement relaxation standard to indicate the first time information and the first parameter information to the terminal.

[0380] For a detailed explanation of the first parameter information, please refer to the relevant explanation in Method 300 above. For the sake of brevity, it will not be repeated here.

[0381] In one possible implementation, the terminal can determine whether the time condition is met based on the first time information, and whether the good cell service quality standard or the non-cell edge standard is met based on the first parameter information; if both the time condition and the good cell service quality standard are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM; if only the time condition is met, or only the good cell service quality standard is met, or neither the time condition nor the good cell service quality standard is met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM.

[0382] In another possible implementation, the terminal can first determine whether the time condition is met based on the first time information. If the time condition is met, the terminal will then initiate an evaluation based on the first parameter information to determine whether the good cell service quality standard is met. If both the time condition and the good cell service quality standard are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM. If only the time condition is met, or only the good cell service quality standard is met, or neither the time condition nor the good cell service quality standard is met, the terminal may not perform measurement relaxation for RLM, BFD, or RRM.

[0383] For example, the base station can use this measurement relaxation standard to indicate first time information and second parameter information to the terminal.

[0384] In one possible implementation, the terminal can determine whether the time condition is met based on the first time information, and whether the low mobility criterion is met based on the second parameter information; if both the time condition and the low mobility criterion are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM; if only the time condition is met, or only the low mobility criterion is met, or neither the time condition nor the low mobility criterion is met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM.

[0385] In another possible implementation, the terminal can first determine whether the time condition is met based on the first time information. If the time condition is met, the terminal will then initiate an evaluation based on the second parameter information to determine whether the low mobility criterion is met. If both the time condition and the low mobility criterion are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM. If only the time condition is met, or only the low mobility criterion is met, or neither the time condition nor the low mobility criterion is met, the terminal may not perform measurement relaxation for RLM, BFD, or RRM.

[0386] For example, the base station can use this measurement relaxation standard to indicate first time information, first parameter information and second parameter information to the terminal.

[0387] In one possible implementation, the terminal can determine whether the time condition is met based on the first time information, and whether the good cell service quality standard or the non-cell edge standard is met based on the first parameter information, and whether the low mobility standard is met based on the second parameter information; if all three are met, the terminal can perform measurement relaxation for RLM, BFD or RRM; if at least one of the three is not met, the terminal can not perform measurement relaxation for RLM, BFD or RRM.

[0388] In another possible implementation, the terminal can first determine whether the time condition is met based on the first time information. If the time condition is met, the terminal will then initiate a determination based on the first parameter information to determine whether the good cell service quality standard or the non-cell edge standard is met, and to assess whether the low mobility standard is met based on the second parameter information. If all three conditions are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM. If at least one of the three conditions is not met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM.

[0389] In another possible implementation, the terminal can first determine whether the time condition is met based on the first time information, and then assess whether the low mobility standard is met based on the second parameter information. If the time condition and the low mobility standard are met, the terminal will then initiate a determination based on the first parameter information to determine whether the good cell service quality standard or the non-cell edge standard is met. If all three are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM. If at least one of the three is not met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM.

[0390] In another possible implementation, the terminal can first determine whether the time condition is met based on the first time information, and then determine whether the good cell service quality standard or the non-cell edge standard is met based on the first parameter information. Only when the above time condition and the good cell service quality standard or the non-cell edge standard are met will the terminal initiate an assessment based on the second parameter information to determine whether the low mobility standard is met. If all three conditions are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM. If at least one of the three conditions is not met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM.

[0391] In another possible implementation, the terminal can first determine whether it meets the good cell service quality standard or the non-cell edge standard based on the first parameter information, and assess whether it meets the low mobility standard based on the second parameter information. Only when the good cell service quality standard, the non-cell edge standard, and the low mobility standard are met will the terminal initiate a determination based on the first time information to determine whether the time condition is met. If all three are met, the terminal can perform measurement relaxation for RLM, BFD, or RRM. If at least one of the three is not met, the terminal can choose not to perform measurement relaxation for RLM, BFD, or RRM.

[0392] For a detailed explanation of the combined use of more first-time information and / or time conditions with other content (e.g., reference location, location-related thresholds, location conditions, first parameter information and / or second parameter information), please refer to the relevant description of the first-time information and / or time conditions involved in Method 300 above. For the sake of brevity, it will not be repeated here.

[0393] Optionally, the terminal reports one or more of the following measurement relaxation states: RLM, BFD, or RRM.

[0394] Measuring relaxation state can be understood as whether the relaxation criteria are met.

[0395] As an example and not a limitation, the terminal can report the measurement relaxation state to the base station through the first auxiliary information; that is, the measurement relaxation state can be carried in the first auxiliary information.

[0396] For a detailed description of how the terminal reports the measured relaxation state, please refer to the relevant description in Method 300 above. For the sake of brevity, it will not be repeated here.

[0397] Optionally, the measurement relaxation criterion, in addition to indicating one or more of the aforementioned reference position, position-related threshold, position conditions, first time information, time conditions, first parameter information, and second parameter information, can also be used to indicate under what circumstances the terminal performs measurement relaxation for RLM, BFD, or RRM, and / or whether the terminal needs to report the measurement relaxation status to the base station. If the base station instructs the terminal to report the measurement relaxation status, the terminal can report to the base station whether it needs to perform or not perform (or exit) measurement relaxation for RLM, BFD, or RRM. If the base station does not instruct the terminal to report the measurement relaxation status, the terminal can report the measurement relaxation status or not. In this case, whether to report the measurement relaxation status depends on the terminal's own configuration information. That is, if the terminal is configured to report the measurement relaxation status, then the terminal can report the measurement relaxation status to the base station; if the terminal is configured not to report the measurement relaxation status, or if the terminal is not configured to report the measurement relaxation status, then the terminal can not report the measurement relaxation status. For a detailed description of this section, please refer to the relevant description in Method 300 above. For the sake of brevity, it will not be repeated here.

[0398] In methods 300 and 500, for connected terminals, before the base station instructs the terminal on the measurement relaxation criteria, the base station needs to know whether the terminal has the ability to perform measurement relaxation based on location conditions and / or time conditions.

[0399] In one possible implementation, the terminal can proactively report to the base station whether it has the capability to perform measurement relaxation based on location and / or time conditions.

[0400] In another possible implementation, the base station may query the terminal to determine whether it has the capability to perform measurement relaxation based on location and / or time conditions. Accordingly, the terminal may respond to the base station's query to inform the base station whether it has the capability to perform measurement relaxation based on location and / or time conditions.

[0401] In another possible implementation, when the terminal switches to an NTN serving cell, the base station associated with the current NTN serving cell can obtain information from the base station associated with the NTN serving cell before the switch whether the terminal has the ability to perform measurement relaxation based on location and / or time conditions.

[0402] Figure 6 This is a schematic diagram illustrating the interaction between a base station and a terminal provided in an embodiment of this application.

[0403] In step 610, the base station sends a first message to the terminal. Accordingly, the terminal receives the first message.

[0404] The first message (e.g., UECapabilityEnquiry) is used to instruct the terminal to report whether it has the ability to perform measurement relaxation based on location and / or time conditions.

[0405] In step 620, the terminal sends a second message to the base station. Correspondingly, the base station receives the second message.

[0406] The second message (e.g., UECapabilityInformation) is used to inform the base station whether the terminal has the ability to perform measurement relaxation based on location and / or time conditions.

[0407] The following combination Figure 7 and Figure 8 The method for measuring relaxation in NTN provided in this application will be briefly explained again.

[0408] Figure 7 This is a schematic diagram of the interaction between a base station and a terminal for the method of measuring relaxation in NTN provided in the embodiments of this application.

[0409] In step 710, the base station sends a broadcast message or RRC proprietary signaling to the terminal, which indicates a measurement relaxation standard carrying a reference position. Accordingly, the terminal receives the broadcast message or RRC proprietary signaling.

[0410] For connected terminals, the base station can indicate to the terminal, via broadcast message or RRC proprietary signaling, that a measurement relaxation standard carrying a reference location is required; for idle terminals, the base station can indicate to the terminal, via broadcast message, that a measurement relaxation standard carrying a reference location is required.

[0411] For detailed explanations of the reference location and measurement relaxation criteria, please refer to the relevant explanations in Method 300 above. For the sake of brevity, they will not be repeated here.
