[0133] Optionally, the ephemeris information includes at least one of the following:

[0134] (1) Orbital information of satellite equipment.

[0135] In some embodiments, the orbit information is used to indicate the orbit of the satellite equipment during operation. Optionally, the names of the orbit information are not limited in this disclosure, and may include, for example, trajectory information, path information, etc.

[0136] (2) Clock information of satellite equipment.

[0137] In some embodiments, the clock information is used to indicate the time of the satellite equipment.

[0138] (3) GPS ephemeris.

[0139] In some embodiments, the GPS ephemeris is used to indicate the precise location of satellites.

[0140] (4) GPS calendar.

[0141] In some embodiments, the GPS almanac is used to indicate the approximate location of satellites.

[0142] Optionally, the accuracy of the ephemeris in this embodiment of the disclosure is greater than that of the almanac.

[0143] In some embodiments, the satellite device is a satellite or other device, and this disclosure does not limit the specific device.

[0144] In some embodiments, the ephemeris information is carried in satellite access station (SAN) information or in the ground gateway station signal corresponding to the satellite; this disclosure does not limit this.

[0145] It should be noted that, in this embodiment of the present disclosure, if there is an overlap between the first frequency domain resources of the ground equipment and the second frequency domain resources of the satellite equipment, the ground equipment may send a request message to the satellite equipment to request the acquisition of the satellite equipment's ephemeris information. In response to the received request message, the satellite equipment may return the ephemeris information to the ground equipment.

[0146] In some embodiments, the ground equipment receives ephemeris information transmitted by the satellite equipment. In this embodiment of the disclosure, the ground equipment can receive the ephemeris information transmitted by the satellite equipment after the satellite equipment transmits it.

[0147] In step S2102, the first frequency domain resources of the ground equipment overlap with the second frequency domain resources of the satellite equipment, and the ground equipment determines the first maximum transmission power based on the ephemeris information.

[0148] In some embodiments, the first frequency domain resource refers to the frequency domain resource of the ground equipment. Alternatively, it can be understood as the first frequency domain resource referring to the spectrum range of the ground equipment. Or, it can be understood as the first frequency domain resource referring to the frequency domain coverage range of the ground equipment.

[0149] In some embodiments, the second frequency domain resource refers to the frequency domain resource of the satellite equipment. Alternatively, it can be understood as the second frequency domain resource referring to the spectrum range of the satellite equipment. Or, it can be understood as the second frequency domain resource referring to the frequency domain coverage range of the satellite equipment.

[0150] In this embodiment of the disclosure, if the first frequency domain resources of the ground equipment overlap with the second frequency domain resources of the satellite equipment, the ground equipment may interfere with the satellite equipment. Therefore, the ground equipment needs to determine the first maximum transmission power based on the ephemeris information to ensure that the power of the terminal's uplink transmission is not greater than the first maximum transmission power.

[0151] In some embodiments, the first frequency domain resources of the ground equipment and the second frequency domain resources of the satellite equipment overlap. It can also be understood that the first frequency domain resources of the ground equipment and the second frequency domain resources of the satellite equipment have some frequency domain resources that are the same or completely the same. This disclosure does not limit this.

[0152] In some embodiments, the first maximum transmit power is used to indicate the maximum power that the terminal is allowed to use when transmitting signals and / or channels when there is overlap between the first frequency domain resources of the ground equipment and the second frequency domain resources of the satellite equipment. Alternatively, it can be understood as the maximum power that the terminal is allowed to use during uplink transmission.

[0153] In some embodiments, the ground equipment is configured with a correspondence between ephemeris information and a second maximum transmit power; based on the ephemeris information, the correspondence is queried, and the second maximum transmit power is determined as the first maximum transmit power. Alternatively, it can be understood that the correspondence is queried based on the ephemeris information, and the second maximum transmit power corresponding to the ephemeris information is determined as the first maximum transmit power. Optionally, the ephemeris information includes orbital information, and the ground equipment determines the first maximum transmit power based on the correspondence between the orbital distance included in the orbital information and the second maximum transmit power. For example, orbit LEO corresponds to a maximum transmit power P1, orbit MEO corresponds to a maximum transmit power P2, and orbit GEO corresponds to a maximum transmit power P3. If the orbital information of the ground equipment indicates orbit LEO, then the first maximum transmit power is determined to be P1.

[0154] It should be noted that this embodiment of the present disclosure uses the determination of the first maximum transmission power based on ephemeris information as an example for illustration. In another embodiment, other methods may be used to determine the first maximum transmission power, and this embodiment of the present disclosure does not limit this method.

[0155] In step S2103, the ground equipment sends the first maximum transmission power to the terminal.

[0156] In some embodiments, the terminal receives a first maximum transmit power sent by ground equipment.

[0157] In this embodiment of the disclosure, after the ground equipment determines the first maximum transmission power, it can indicate the first maximum transmission power to the terminal, and then the terminal can transmit signals and / or channels based on the first maximum transmission power.

[0158] In some embodiments, the terminal transmitting signals and / or channels can also be understood as the terminal transmitting uplink signals or transmitting transmission power, and this disclosure does not limit this.

[0159] In some embodiments, the first maximum transmit power is carried in the p-max IE or in other messages, which is not limited in this disclosure.

[0160] Step S2104: The terminal sends signals and / or channels to the ground equipment.

[0161] In some embodiments, the ground equipment receives signals and / or channels transmitted by the terminal.

[0162] Wherein, the transmission power of the signal and / or channel is not greater than the first maximum transmission power. Alternatively, it can be understood that the transmission power of the signal and / or channel is less than or equal to the first maximum transmission power, and this disclosure does not limit this aspect.

[0163] In this embodiment of the disclosure, the terminal transmits signals or channels according to the transmit power, and this embodiment of the disclosure is not limited in this respect. Optionally, in this embodiment of the disclosure, the signals and / or channels transmitted by the terminal are uplink signals and / or uplink channels.

[0164] It should be noted that the embodiments disclosed herein are illustrated by the example of the ground equipment sending a first maximum transmission power to the terminal, and the terminal performing uplink transmission based on the first maximum transmission power. Alternatively, step S2104 can be understood as an optional step. In another embodiment, the ground equipment may not send the first maximum transmission power to the terminal, but instead adjust the terminal's transmission power based on the first maximum transmission power.

[0165] In some embodiments, the ground equipment receives power information sent by the terminal, determines the current transmission power of the terminal based on the power information, and adjusts the transmission power of the terminal based on the current transmission power and the first maximum transmission power.

[0166] Optionally, the power information includes the terminal's configured fourth maximum transmit power and the terminal's PHR, and the difference between the fourth maximum transmit power and the PHR is determined as the terminal's current transmit power. The fourth maximum transmit power refers to the maximum transmit power supported by the terminal itself.

[0167] In some embodiments, if the current transmit power is greater than the first maximum transmit power, the current transmit power is reduced. Alternatively, it can be understood that if the terminal reports a current transmit power greater than the first maximum transmit power, the ground equipment needs to reduce the current transmit power so that the reduced transmit power does not exceed the first maximum transmit power. Optionally, the ground equipment reduces the terminal's current transmit power by a first value each time. For example, if the ground equipment reduces the current transmit power by a first value, and the reduced transmit power does not exceed the first maximum transmit power, the terminal can use the reduced transmit power. If the reduced transmit power still exceeds the first maximum transmit power, the reduced transmit power continues to be reduced by the first value until the reduced transmit power does not exceed the first maximum transmit power.

[0168] In some embodiments, the current transmit power is less than or equal to a first maximum transmit power, and the current transmit power can be increased or kept unchanged. In this embodiment, if the current transmit power is less than or equal to the first maximum transmit power, it indicates that the transmit power currently used by the terminal meets the requirements, and no adjustment to the current transmit power is necessary. Alternatively, the maximum range by which the ground equipment can increase the current transmit power is the difference between the first maximum transmit power and the current transmit power.

[0169] In some embodiments, the overlapping area may be determined based on the deployment of satellite equipment and ground equipment.

[0170] In some embodiments, ground equipment may determine the overlapping area based on received satellite ephemeris information.

[0171] In one embodiment, the terminal reports its location information to the ground equipment, which then determines whether the terminal is in an overlapping area based on the location information.

[0172] The communication method based on transmission power disclosed in this embodiment may include at least one of steps S2101 to S2104. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, step S2103 may be implemented as an independent embodiment, step S2104 may be implemented as an independent embodiment, steps S2101 and S2102 may be implemented as independent embodiments, steps S2101 and S2103 may be implemented as independent embodiments, steps S2101 and S2104 may be implemented as independent embodiments, steps S2102 and S2103 may be implemented as independent embodiments, steps S2102 and S2104 may be implemented as independent embodiments, and steps S2103 and S2104 may be implemented as independent embodiments, but are not limited thereto.

[0173] In some embodiments, at least one of steps S2101-S2104 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0174] In some embodiments, other alternative implementations may be described before or after the specification corresponding to FIG2A.

[0175] Figure 2B is an interactive schematic diagram of a communication method based on transmission power according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiments of the present disclosure relate to a communication method based on transmission power, the method including:

[0176] Step S2201: The satellite equipment sends an interference indication.

[0177] In some embodiments, the interference indication is used to indicate the degree of interference between ground equipment and satellite equipment. Alternatively, it can be understood as indicating whether the satellite equipment is being interfered with by ground equipment.

[0178] Optionally, the satellite equipment may transmit interference instructions via broadcast or other means, and this disclosure does not limit the specific methods used.

[0179] Optionally, the interference indication includes at least one of the following:

[0180] (1) Information used to indicate whether there is interference from ground equipment to satellite equipment.

[0181] For example, information used to indicate whether interference exists between ground equipment and satellite equipment includes a first identifier or a second identifier. The first identifier indicates that interference exists between ground equipment and satellite equipment, or can be understood as indicating that interference exists between ground equipment and satellite equipment. The second identifier indicates that interference does not exist between ground equipment and satellite equipment, or can be understood as indicating that interference does not exist between ground equipment and satellite equipment.

[0182] (2) Interference level.

[0183] In some embodiments, a higher interference level indicates a greater degree of interference between the ground equipment and the satellite equipment. For example, the interference level may include three levels: low, medium, and high, or it may include other levels, which are not limited in this disclosure.

[0184] In some embodiments, the ground equipment receives an interference indication sent by the satellite equipment. In this embodiment of the disclosure, the ground equipment can receive the interference indication sent by the satellite equipment after the satellite equipment sends it.

[0185] It should be noted that, in this embodiment of the present disclosure, if the first frequency domain resources of the ground equipment and the second frequency domain resources of the satellite equipment overlap, the ground equipment may send a request message to the satellite equipment to request to obtain the interference indication of the satellite equipment. In response to the received request message, the satellite equipment may return an interference indication to the ground equipment.

[0186] In step S2202, the first frequency domain resources of the ground equipment overlap with the second frequency domain resources of the satellite equipment, and the ground equipment determines the first maximum transmit power based on the interference indication.

[0187] In some embodiments, the first frequency domain resource refers to the frequency domain resource of the ground equipment. Alternatively, it can be understood as the first frequency domain resource referring to the spectrum range of the ground equipment. Or, it can be understood as the first frequency domain resource referring to the frequency domain coverage range of the ground equipment.

[0188] In some embodiments, the second frequency domain resource refers to the frequency domain resource of the satellite equipment. Alternatively, it can be understood as the second frequency domain resource referring to the spectrum range of the satellite equipment. Or, it can be understood as the second frequency domain resource referring to the frequency domain coverage range of the satellite equipment.

[0189] In this embodiment of the disclosure, if the first frequency domain resources of the ground equipment overlap with the second frequency domain resources of the satellite equipment, the ground equipment may interfere with the satellite equipment. Therefore, the ground equipment needs to determine the first maximum transmission power based on the interference indication, so as to ensure that the power of the terminal for uplink transmission is not greater than the first maximum transmission power.

[0190] In some embodiments, the first frequency domain resources of the ground equipment and the second frequency domain resources of the satellite equipment overlap. It can also be understood that the first frequency domain resources of the ground equipment and the second frequency domain resources of the satellite equipment have some frequency domain resources that are the same or completely the same. This disclosure does not limit this.

[0191] In some embodiments, the first maximum transmit power is used to indicate the maximum power that the terminal is allowed to use when transmitting signals and / or channels when there is overlap between the first frequency domain resources of the ground equipment and the second frequency domain resources of the satellite equipment. Alternatively, it can be understood as the maximum power that the terminal is allowed to use during uplink transmission.

[0192] In some embodiments, the ground equipment is configured with a correspondence between interference levels and a third maximum transmit power. By querying this correspondence, the third maximum transmit power is determined as the first maximum transmit power. Alternatively, it can be understood as querying the correspondence based on the interference level to determine the third maximum transmit power corresponding to the interference level as the first maximum transmit power. Optionally, the interference indication includes the interference level, and the ground equipment determines the first maximum transmit power according to the correspondence between the interference level and the third maximum transmit power. For example, a low interference level corresponds to a maximum transmit power P1, a medium interference level corresponds to a maximum transmit power P2, and a high interference level corresponds to a maximum transmit power P3. If the ground equipment indicates a low interference level, then the first maximum transmit power is determined to be P1.

[0193] It should be noted that the embodiments disclosed herein are illustrated using the example of determining the first maximum transmit power based on interference indication. In another embodiment, other methods may be used to determine the first maximum transmit power, and the embodiments disclosed herein do not limit this method.

[0194] In step S2203, the ground equipment sends the first maximum transmission power to the terminal.

[0195] In some embodiments, the terminal receives a first maximum transmit power sent by ground equipment.

[0196] In this embodiment of the disclosure, after the ground equipment determines the first maximum transmission power, it can indicate the first maximum transmission power to the terminal, and then the terminal can perform uplink transmission based on the first maximum transmission power.

[0197] In some embodiments, the first maximum transmit power is carried in MAC CE or DCI, or in other messages, which is not limited in this disclosure.

[0198] Step S2204: The terminal sends signals and / or channels to the ground equipment.

[0199] In some embodiments, the ground equipment receives signals and / or channels transmitted by the terminal.

[0200] Wherein, the transmission power of the signal and / or channel is not greater than the first maximum transmission power. Alternatively, it can be understood that the transmission power of the signal and / or channel is less than or equal to the first maximum transmission power, and this disclosure does not limit this aspect.

[0201] In this embodiment of the disclosure, the terminal transmits signals or channels according to the transmit power, and this embodiment of the disclosure is not limited in this respect. Optionally, in this embodiment of the disclosure, the signals and / or channels transmitted by the terminal are uplink signals and / or uplink channels.

[0202] It should be noted that the embodiments disclosed herein are illustrated by the example of the ground equipment sending a first maximum transmission power to the terminal, and the terminal performing uplink transmission based on the first maximum transmission power. Alternatively, step S2204 can be understood as an optional step. In another embodiment, the ground equipment may not send the first maximum transmission power to the terminal, but instead adjust the terminal's transmission power based on the first maximum transmission power.

[0203] In some embodiments, the ground equipment receives power information sent by the terminal, determines the current transmission power of the terminal based on the power information, and adjusts the transmission power of the terminal based on the current transmission power and the first maximum transmission power.

[0204] Optionally, the power information includes the terminal's configured fourth maximum transmit power and the terminal's PHR, and the difference between the fourth maximum transmit power and the PHR is determined as the terminal's current transmit power. The fourth maximum transmit power refers to the maximum transmit power supported by the terminal itself.

[0205] In some embodiments, if the current transmit power is greater than the first maximum transmit power, the current transmit power is reduced. Alternatively, it can be understood that if the terminal reports a current transmit power greater than the first maximum transmit power, the ground equipment needs to reduce the current transmit power so that the reduced transmit power does not exceed the first maximum transmit power. Optionally, the ground equipment reduces the terminal's current transmit power by a first value each time. For example, if the ground equipment reduces the current transmit power by a first value, and the reduced transmit power does not exceed the first maximum transmit power, the terminal can use the reduced transmit power. If the reduced transmit power still exceeds the first maximum transmit power, the reduced transmit power continues to be reduced by the first value until the reduced transmit power does not exceed the first maximum transmit power.

[0206] In some embodiments, the current transmit power is less than or equal to a first maximum transmit power, and the current transmit power can be increased or kept unchanged. In this embodiment, if the current transmit power is less than or equal to the first maximum transmit power, it indicates that the transmit power currently used by the terminal meets the requirements, and no adjustment to the current transmit power is necessary. Alternatively, the maximum range by which the ground equipment can increase the current transmit power is the difference between the first maximum transmit power and the current transmit power.

[0207] In some embodiments, the terminal in this disclosure may refer only to terminals in the overlapping area, rather than all terminals within the cell. That is, terminals outside the overlapping area are not subject to the maximum allowed power limit.

[0208] In some embodiments, the overlapping area may be determined based on the deployment of satellite equipment and ground equipment.

[0209] In some embodiments, ground equipment may determine the overlapping area based on received satellite ephemeris information.

[0210] In one embodiment, the terminal reports its location information to the ground equipment, which then determines whether the terminal is in an overlapping area based on the location information.

[0246] Figure 6A is a flowchart illustrating a communication method based on transmission power according to an embodiment of the present disclosure. As shown in Figure 6A, the present disclosure relates to a communication method based on transmission power, the method including:

[0247] In step S6101, when a ground cellular base station needs to share satellite spectrum, the ground cellular base station receives ephemeris information from satellite communication. Based on the ephemeris information, the base station estimates the maximum allowable transmission power of the terminal and notifies the terminal of the maximum allowable transmission power.

[0248] In some embodiments, when a ground cellular base station needs to share satellite spectrum, the ground cellular base station receives ephemeris information from satellite communication. Based on the ephemeris information, the base station estimates the maximum allowable transmit power of the terminal and sets the maximum allowable transmit power P. smax The terminal is notified. When the terminal is transmitting uplink, the maximum transmit power shall not exceed the maximum allowable transmit power.

[0249] In some embodiments, the ground cellular base station receives ephemeris information from satellite communication, satellite access station (SAN) information from airborne satellite communication, and ground gateway station signals corresponding to the satellite.

[0250] In some embodiments, the ephemeris information may include satellite orbit information, clock information, and GPS-specific ephemeris and almanac information, which are used by the base station to determine the satellite's orbital altitude and / or trajectory.

[0251] In some embodiments, the base station estimates the maximum allowable transmit power P of the terminal based on ephemeris information. smax In one embodiment, the base station can determine the terminal's maximum transmit power P based on satellite orbit information. smax In one embodiment, a lookup table may be built-in, as shown in the table below. Note: More tracks can be built-in.

[0252] In some embodiments, the maximum allowable transmit power P smax The notification to the terminal can, in one embodiment, be indicated using an existing p-max IE. In another embodiment, it can also be sent to the terminal via other messages.

[0253] In some embodiments, when the terminal is making an uplink transmission, the maximum transmission power does not exceed the maximum allowable transmission power.

[0254] In another embodiment, the base station may not display the maximum permissible transmit power P. smax The terminal is notified, but when controlling the terminal's power, it is necessary to ensure that the terminal's maximum power is lower than the maximum allowable transmit power. For example, the terminal's current transmit power is determined by reporting its PHR, and based on the current transmit power P... current The maximum allowed transmit power is used to determine how to adjust the terminal's transmit power. For example: when P... current Greater than P smax Reduce transmission power, P current Less than or equal to P smax At that time, the terminal can also adjust the power to a maximum of: P smax -P current

[0255] In another embodiment, the terminals in this disclosure may refer only to terminals in the overlapping area, rather than all terminals within the cell. That is, terminals outside the overlapping area are not subject to the maximum allowed power limit.

[0256] In another embodiment, the overlapping area may be determined based on the deployment of satellite and terrestrial cellular base stations. In one embodiment, the base station may determine the overlapping area based on received satellite ephemeris information.

[0257] In one embodiment, the terminal reports its location information to the base station, which then determines whether the terminal is in an overlapping area based on the location information.

[0258] Figure 6B is a flowchart illustrating a communication method based on transmission power according to an embodiment of the present disclosure. As shown in Figure 6B, the present disclosure relates to a communication method based on transmission power, the method including:

[0259] In step S6201, the terrestrial cellular base station can also receive interference indications from satellites. Based on the received interference indications, the terrestrial cellular base station determines the maximum allowable transmission power of the terminal and notifies the terminal of the maximum allowable transmission power. When the terminal performs uplink transmission, the maximum transmission power does not exceed the maximum allowable transmission power.

[0260] In some embodiments, the interference indication may include whether interference exists, and the amount or level of interference. The level of interference may include low, medium, or high. Based on the above information, the base station determines the maximum allowable transmit power of the terminal.

[0261] In some embodiments, the terminal can be dynamically notified. In one embodiment, the maximum allowed transmit power of the terminal can be indicated via MAC CE or DCI.

[0262] In another embodiment, the base station may not display the maximum permissible transmit power P. smax The terminal is notified, but when controlling the terminal's power, it is necessary to ensure that the terminal's maximum power is lower than the maximum allowable transmit power. For example, the terminal's current transmit power is determined by reporting its PHR, and based on the current transmit power P... current The maximum allowed transmit power is used to determine how to adjust the terminal's transmit power. For example: when P... current Greater than P smax Reduce transmission power, P current Less than or equal to P smax At that time, the terminal can also adjust the power to a maximum of: P smax -P current
