[0119] In some embodiments, data, information, etc. may be obtained with the user's consent.

[0120] In addition, each element, each row, or each column in the table of the embodiment of the present disclosure can be implemented as an independent embodiment, and the combination of any elements, any rows, and any columns can also be implemented as an independent embodiment.

[0121] In some embodiments, the E-UTRAN TN, such as long term evolution (LTE), provides information about NR frequencies and NR neighbor cells through system information block (SIB) 24, so that the terminal can perform inter-system cell reselection, that is, reselect from NR cell to NR cell.

[0122] In some embodiments, when a terminal reselects from an E-UTRAN TN to another cell, the following measurement principles are followed:

[0123] The UE shall apply the following rules to the E-UTRAN inter-frequency and inter-RAT frequency indicated in the system information with the priority defined in 5.2.4.1:

[0124] - For reselection of an E-UTRAN inter-frequency or inter-RAT frequency with a higher priority than the current E-UTRA frequency, the UE shall perform measurements on the higher priority E-UTRAN inter-frequency or RAT frequency.

[0125] - For E-UTRAN inter-frequencies with a reselection priority equal to or lower than the current E-UTRA frequency, and for inter-RAT frequencies with a reselection priority lower than the current E-UTRAN frequency:

[0126] If measurement is performed using RSS and the serving cell satisfies Srxlev>SnonInterSearchP, where Srxlev represents the received strength of the reference signal of the serving cell and SnonInterSearchP represents the received strength of the reference signal of the neighboring cell:

[0127] The UE may choose not to perform measurements on E-UTRAN inter-frequency or inter-RAT frequency cells of the same or lower priority unless the UE is triggered to measure an E-UTRAN inter-frequency configured with reallocated different inter-frequency handover information (InterFreqInfo).

[0128] Otherwise, if the serving cell satisfies Srxlev>SnonIntraSearchP and Squal>SnonInterSearchQ, where Squal represents the received quality of the reference signal of the serving cell and SnonInterSearchQ represents the received quality of the reference signal of the neighboring cell:

[0129] The UE may choose not to perform measurements on E-UTRAN inter-frequency or inter-RAT frequency cells of the same or lower priority unless the UE is triggered to measure an E-UTRAN inter-frequency configured with reallocated InterFreqInfo.

[0130] - Otherwise, the UE shall perform measurements on E-UTRAN inter-frequency or inter-RAT frequency cells with equal or lower priority.

[0131] Currently, 3GPP has standardized IoT NTN and NR NTN. Technologies related to terminal migration from terrestrial networks to non-terrestrial networks are also being widely researched. For example, the terrestrial network is the evolved universal terrestrial radio access network technology node (E-UTRAN TN). For example, the non-terrestrial network is the IoT NTN or NR NTN.

[0132] In some embodiments, the E-UTRAN TN needs to provide satellite information of the NR NTN. From the perspective of the UE, the NR NTN is the neighboring cell of the UE, that is, the E-UTRAN TN needs to provide satellite information of the neighboring cell NR NTN, for example, satellite ephemeris information. The UE can measure the NR NTN based on the information of the NR NTN satellite, thereby enabling the UE to perform cell reselection, for example, the UE reselects from the EUTRAN TN to the NR NTN.

[0133] In some embodiments, when a UE performs cell reselection, if the measurement conditions are met, the UE may perform inter-frequency measurements, i.e., measurements of neighboring cells with a different frequency from the serving cell; or intra-frequency measurements, i.e., measurements of neighboring cells with the same frequency as the serving cell; or inter-RAT frequency measurements, i.e., measurements of neighboring cells of different systems. Regarding inter-RAT frequency, considering the satellite mobility of NR NTN, there are not always NR NTN neighboring cells. If the UE still measures the NR NTN frequency, unnecessary measurements will result, increasing the power consumption of the UE.

[0134] Therefore, the present disclosure provides a communication method, which receives reference location information and / or distance threshold values ​​sent by a terrestrial network so that a non-terrestrial network can be subsequently measured based on the reference location information and / or distance threshold values, that is, measurement is performed only when the reference location information and / or distance threshold values ​​meet the conditions, so as to avoid unnecessary measurements and power consumption of the terminal caused by direct measurement.

[0146] FIG2 is a schematic diagram illustrating an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to a communication method for use in a communication system 100, the method comprising:

[0147] In step S2101 , the network device 102 sends reference location information and / or a distance threshold of a non-terrestrial network to the terminal 101 .

[0148] In some embodiments, terminal 101 receives reference location information and / or a distance threshold value of a non-terrestrial network sent by network device 102. The reference location information may be satellite location information, or cell location information. Alternatively, the reference location information may be location information of a frequency of the non-terrestrial network. It is understood that there may be satellites or cells on the frequency of the non-terrestrial network, and the location information of the frequency of the non-terrestrial network may be understood as the location information of the satellites or cells on that frequency. The reference location information may be a relative value or an absolute value. The reference location information may be represented by coordinates, but is not limited thereto.

[0149] In some embodiments, the network device 102 may be a terrestrial network device or a non-terrestrial network device. This disclosure uses the network device 102 as an example of a terrestrial network device, but is not limited thereto.

[0150] In some embodiments, reference location information and / or distance threshold value is used for the terminal to measure the non-terrestrial network.

[0151] In some embodiments, the terrestrial network may be, for example, an E-UTRAN TN, and the non-terrestrial network may be an IoT NTN or an NR NTN. However, this example is merely exemplary, and the terrestrial network and the non-terrestrial network are not limited thereto.

[0152] In some embodiments, the reference location information and / or distance threshold value of the non-terrestrial network can be received via system information used to receive the ephemeris information of the non-terrestrial network. Specifically, the reference location information and / or distance threshold value can be included in the system information that transmits the ephemeris information of the non-terrestrial network, and the reference location information and / or distance threshold value do not need to be transmitted separately, thereby reducing signaling consumption. Of course, the reference location information and / or distance threshold value can also be transmitted via other information or can be transmitted separately, and this disclosure is not limited thereto.

[0153] In some embodiments, the reference location information and / or the distance threshold value may be sent by other devices, or may be determined by the terminal in other ways. For example, the terminal may determine the distance threshold value based on a predefined value, or the terminal may determine the distance threshold value based on the rules specified in the protocol. For another example, the network device may pre-configure the distance threshold value without dynamically configuring the distance threshold value each time. In some embodiments, the reference location information and / or the distance threshold value corresponds to a cell. That is, the reference location information is the reference location information of a cell on a satellite, and the cell corresponds to a distance threshold value. The reference location information and / or the distance threshold value in this embodiment can be used to measure the cell. That is, when the reference location information and / or the distance threshold value meet the conditions, the corresponding cell is measured, otherwise it is not measured.

[0154] In some embodiments, the reference position information and / or the distance threshold value corresponds to a single satellite. That is, the reference position information may be the reference position information of a single satellite, and the satellite corresponds to a single distance threshold value. The reference position information and / or the distance threshold value in this embodiment can be used to measure the satellite. Specifically, the corresponding satellite is measured only when the reference position information and / or the distance threshold value meet the conditions; otherwise, the measurement is not performed.

[0155] In some embodiments, the reference location information and / or distance threshold value corresponds to a frequency of a non-terrestrial network. The reference location information and example threshold value in this embodiment can be used to measure the frequency of the non-terrestrial network. It will be appreciated that a frequency of a non-terrestrial network may have one or more satellites. Alternatively, a frequency of a non-terrestrial network may have one or more cells. The terminal measures the frequency of the non-terrestrial network to determine whether to reselect to a satellite or cell on that frequency.

[0156] In some embodiments, the reference location information and / or distance threshold value may include multiple sets of reference location information and / or distance threshold values. Each set of reference location information and / or distance threshold value includes one reference location information and one distance threshold value. Each set of reference location information and / or distance threshold value corresponds to one cell, or each set of reference location information and / or distance threshold value corresponds to one satellite, or each set of reference location information and / or distance threshold value corresponds to one frequency of a non-terrestrial network.

[0157] It is understood that the terminal may receive a reference location information and a distance threshold value sent by a network device, and use this to measure the cell, satellite, or frequency corresponding to the reference location information and / or distance threshold value. The terminal may also receive multiple sets of reference location information and / or distance threshold values ​​sent by the network device. Each set of reference location information is used to measure a corresponding cell, satellite, or frequency.

[0158] In some embodiments, the frequency of a satellite-associated non-terrestrial network. For example, when the reference location information and / or distance threshold value received by the terminal corresponds to a satellite, or when one set of reference location information and / or distance threshold values ​​received by the terminal corresponds to a satellite, the terminal may measure the frequency of the non-terrestrial network associated with the satellite based on the reference location information and / or distance threshold value corresponding to the satellite. If the measurement result meets the cell reselection conditions, the terminal may choose to reselect to the satellite.

[0159] In some embodiments, a cell is associated with a frequency of a non-terrestrial network. For example, when the reference location information and / or distance threshold received by the terminal corresponds to a cell, or when one set of reference location information and / or distance threshold received by the terminal corresponds to a cell, the terminal may measure the frequency of the non-terrestrial network associated with the satellite based on the reference location information and / or distance threshold corresponding to the cell. If the measurement result meets the cell reselection conditions, the terminal may choose to reselect to the satellite.

[0160] In step S2102, the terminal 101 measures the non-terrestrial network based on the reference location information and / or the distance threshold.

[0161] In some embodiments, a terminal may measure a non-terrestrial network based on reference location information and / or a distance threshold. For example, the terminal may determine the distance between itself and the non-terrestrial network based on its own location information and the received reference location information of the non-terrestrial network. When the distance is greater than the distance threshold, the non-terrestrial network is not measured. When the distance is not greater than the distance threshold, the non-terrestrial network is measured. In other words, when the distance is less than or equal to the distance threshold, the non-terrestrial network may be measured.

[0162] In some embodiments, when reference location information and / or a distance threshold value corresponds to a cell, or when a set of reference location information and / or distance threshold values ​​corresponds to a cell, the distance between the terminal and the cell corresponding to the reference location information can be determined. That is, the distance between the terminal's location information and the cell's reference location information is calculated. When the distance is not greater than the corresponding distance threshold value, the frequency associated with the cell is measured. Conversely, when the distance is greater than the distance threshold value, the frequency associated with the cell is not measured. The corresponding threshold value can be understood as the threshold value corresponding to the reference location information or the distance threshold value corresponding to the cell. That is, when there are multiple sets of reference location information and / or distance threshold values, the distance threshold values ​​in each set can be the same or different. For example, if the first set of reference location information X1 and distance threshold value Y1 corresponds to cell A, and the second set of reference location information X2 and distance threshold value corresponds to cell B, the distance between the terminal and cell A should be compared with the corresponding distance threshold value Y1. When the distance between the terminal and cell A is not greater than Y1, the frequency associated with cell A is measured. Accordingly, the distance between the terminal and cell B should be compared with the corresponding distance threshold value Y2. When the distance between the terminal and cell B is not greater than Y2, the frequency associated with cell B is measured. The distance threshold values ​​corresponding to the frequencies of different cells, different satellites, and different non-terrestrial networks can be the same or different.

[0163] In some embodiments, when the reference position information and / or the distance threshold value corresponds to a satellite, or a set of reference position information and / or the distance threshold value corresponds to a satellite, the distance between the terminal and the satellite corresponding to the reference position information can be determined. That is, the distance between the terminal's position information and the reference position information corresponding to the satellite is calculated. When the distance is not greater than the corresponding distance threshold value, the frequency associated with the satellite is measured. Conversely, when the distance is greater than the distance threshold value, the frequency associated with the satellite is not measured. The corresponding threshold value can be understood as a threshold value corresponding to the reference position information, or as a distance threshold value corresponding to the satellite, which will not be further described in this disclosure.

[0164] In some embodiments, when reference location information and / or a distance threshold value corresponds to a frequency of a non-terrestrial network, or when a set of reference location information and / or distance threshold values ​​corresponds to a frequency of a non-terrestrial network, the distance between the terminal and the reference location information corresponding to the frequency of the non-terrestrial network can be determined. When the distance is not greater than the corresponding distance threshold value, the frequency of the non-terrestrial network is measured. Conversely, when the distance is greater than the distance threshold value, the frequency of the non-terrestrial network is not measured. The corresponding threshold value can be understood as a threshold value corresponding to the reference location information, or as a distance threshold value corresponding to the frequency of the non-terrestrial network, which will not be further described in this disclosure.

[0165] In some embodiments, when the measurement results meet conditions, the terminal can reselect to a non-terrestrial network. For example, when the frequency associated with the measured cell meets conditions, the terminal can reselect to that cell. When the frequency associated with the measured satellite meets conditions, the terminal can reselect to that satellite. When the frequency of the measured non-terrestrial network meets conditions, the terminal can reselect to the satellite or cell on that frequency.

[0166] In some embodiments, if the frequency of a non-terrestrial network is associated with multiple satellites, that is, when multiple sets of reference position information and / or satellites corresponding to distance thresholds received by the terminal are associated with the same frequency of a non-terrestrial network, then when the distance between any satellite and the terminal is not greater than the corresponding distance threshold, the frequency of the non-terrestrial network is measured.

[0167] In some embodiments, if the frequency of a non-terrestrial network is associated with multiple cells, that is, when the terminal receives multiple sets of reference location information and / or cells corresponding to distance thresholds associated with the same non-terrestrial network frequency, then when the distance between any satellite and the terminal is not greater than the corresponding distance threshold, the frequency of the non-terrestrial network is measured.

[0168] In some embodiments, if the frequency of the non-terrestrial network is associated with a satellite and a cell. That is, when the terminal receives multiple sets of reference position information and / or distance threshold values, the satellite corresponding to one or more sets of reference position information and / or distance threshold values ​​is associated with the same frequency as the cell corresponding to one or more sets of reference position information and / or distance threshold values. Then when the distance between any satellite or cell and the terminal is not greater than the corresponding distance threshold value, the frequency of the terrestrial network is measured. For example, a cell and a satellite are associated with the frequency of the same non-terrestrial network, then when the distance between any one of the cell and the satellite and the terminal is not greater than the corresponding distance threshold value, the frequency of the non-terrestrial network can be measured. For another example, multiple cells and multiple satellites are associated with the frequency of the same non-terrestrial network, then when the distance between any one of the cells or any one of the satellites and the terminal is not greater than the corresponding distance threshold value, the frequency of the non-terrestrial network can be measured.

[0169] In some embodiments, when a cell reselection measurement criterion is met, the frequency of a non-terrestrial network is measured based on the reference location information and / or a distance threshold. That is, before measuring the frequency of a non-terrestrial network based on the reference location information and / or the distance threshold, it may be determined whether the cell reselection measurement criterion is met. When the reselection criterion is met, the non-terrestrial network is measured based on the reference location information and / or the distance threshold. For example, when the cell reselection measurement criterion is met and the distance between the terminal and the cell corresponding to the reference location information is not greater than the corresponding distance threshold, the frequency of the non-terrestrial network associated with the cell is measured. For another example, when the cell reselection measurement criterion is met and the distance between the terminal and the satellite corresponding to the reference location information is not greater than the corresponding distance threshold, the frequency of the non-terrestrial network associated with the satellite is measured. For another example, when the cell reselection measurement criterion is met and the distance between the terminal and the reference location information corresponding to the frequency of the non-terrestrial network is not greater than the corresponding distance threshold, the frequency of the non-terrestrial network is measured. It will be understood that this embodiment can be used in combination with any of the above embodiments, and the present disclosure does not provide examples one by one, but is not limited to these.

[0170] The cell reselection measurement criteria in the present disclosure may also be neighboring cell measurement criteria, which are not described one by one in this disclosure.

[0171] In some embodiments, the cell reselection measurement criterion or the neighbor cell measurement criterion is a criterion related to the signal strength and / or quality of the serving cell. That is, when the signal strength and / or quality of the serving cell meet certain criteria, the UE needs to initiate neighbor cell measurement. For example, it can be that the reference signal reception strength of the serving cell is less than that of the neighbor cell, that is, Srxlev < SintraSearchP. Another example can be that the reference signal reception strength of the serving cell is less than that of the neighbor cell, and the reference signal reception quality of the serving cell is less than that of the neighbor cell, that is, Srxlev < SIntraSearchP and Squal < SIntraSearchQ.

[0172] In some embodiments, when a non-terrestrial network is configured for redirection or a frequency of a non-terrestrial network is configured, the frequency of the non-terrestrial network is measured based on reference location information and / or a distance threshold value. That is, before measuring the frequency of the non-terrestrial network based on reference location information and / or a distance threshold value, it can be determined whether a non-terrestrial network is configured or a frequency of a non-terrestrial network is configured. When a non-terrestrial network is configured or a frequency of a non-terrestrial network is configured, the frequency of the non-terrestrial network is measured based on reference location information and / or a distance threshold value. For example, when a non-terrestrial network is configured or a frequency of a non-terrestrial network is configured, and the distance between the terminal and the cell corresponding to the reference location information is not greater than the corresponding distance threshold value, the frequency of the non-terrestrial network associated with the cell is measured. Another example, when a non-terrestrial network is configured or a frequency of a non-terrestrial network is configured, and the distance between the terminal and the satellite corresponding to the reference location information is not greater than the corresponding distance threshold value, the frequency of the non-terrestrial network associated with the satellite is measured. Another example, when a non-terrestrial network is configured or a frequency of a non-terrestrial network is configured, and the distance between the terminal and the reference location information corresponding to the frequency of the non-terrestrial network is not greater than the corresponding distance threshold value, the frequency of this non-terrestrial network is measured. It can be understood that this embodiment can be used in combination with any of the above embodiments, and the present disclosure does not list them one by one, but is not limited thereto.

[0173] In some embodiments, it can be determined that the frequency priority of the non-terrestrial network is lower than or equal to the frequency priority of the terminal's serving cell. That is, when the frequency priority of the non-terrestrial network is lower than or equal to the frequency priority of the terminal's serving cell, the frequency of the non-terrestrial network is measured based on reference location information and / or a distance threshold value.

[0174] In some embodiments, when the frequency priority of the non-terrestrial network is lower than or equal to the frequency priority of the terminal's serving cell, and the cell reselection measurement criterion is satisfied, the frequency of the non-terrestrial network is measured based on reference location information and / or a distance threshold value.
