Background of the Invention In a non-terrestrial network (NTN) system, the beam is constantly moving or redirected as the satellite moves, so the link quality for uplink signal transmission by the terminal device is constantly changing. Furthermore, beams from different types of satellites have different impacts on the link quality.

If the transmission power is too high, unnecessary power consumption will occur; and if it is too low, the transmission quality of the uplink signal cannot be guaranteed.

Complete Description of the Invention The present invention will be explained further with reference to the drawings and embodiments. In the NTN system, satellites move, and the coverage area of beams or cells moves with the movement of the satellites. The beams are constantly moving or being shifted, so the link quality for the uplink signal transmission by the terminal devices is constantly changing. Furthermore, beams from different types of satellites have different impacts on the link quality. Since the transmission power of the terminal devices cannot dynamically adapt to the movement or shifting of beams, the flexibility of power control is poor, which seriously affects the quality and reliability of communication. According to the case of beam movement and shifting in NTN, the service node preconfigures and displays the power parameter package to the terminal devices, thereby realizing flexible indication and control of the terminal devices' transmission power. Figure 1 is a flowchart of a power control method provided by an embodiment. The power control method, in its implementation, is applied to a service node, for example, a base station. As shown in Figure 1, the method provided in this embodiment includes steps (110) and (120). In step (110), configuration information is transmitted, which is used to indicate the N power parameter packets, where N is a positive integer. In step (120), the uplink data is received, wherein the transmission power of the uplink data is determined by the terminal device according to the configuration information. In this embodiment, the service node preconfigures N power parameter packages and indicates the packages to the terminal device through configuration information. The N power parameter packages are selected and used by the terminal device in the case of different reference signals or corresponding carrier files, becoming the basis for calculating the transmission power of the uplink data. In the process of indicating the N power parameter packages, the correspondence between the N power parameter packages and different files, different reference signals or different carriers can be indicated, for example, the first power parameter package corresponds to the first file and the second power parameter package corresponds to the second file.In response to a terminal device transmitting uplink data using the first beam (using the first beam as the serving beam), the corresponding transmission power on the first beam can be calculated based on the first power parameter packet; and in response to a terminal device transmitting uplink data using the second beam (using the second beam as the serving beam), the corresponding transmission power on the second beam can be calculated based on the second power parameter packet. In addition, if a serving beam switch occurs, for example, the serving beam is switched from the first beam to the second beam, the terminal device can change the power parameter packet used according to the indication of the configuration information, so as to accurately calculate the transmit power and adapt to the movement or switching of the beam. The service node displays the preconfigured power parameter package to the terminal device through configuration information, providing a basis for the terminal device to calculate the transmission power. In this way, the service node realizes flexible indication and control of the transmission power of the terminal device, and improves the reliability of power control. In an embodiment, N power parameter packages are associated with L bundles, where L is a positive integer. In this embodiment, there is a correlation between the N power parameter packets and the L bundle. A bundle, in the L bundle, used to transmit the uplink data is a serving bundle. The terminal device can select the corresponding power parameter packets according to the serving bundle, and calculate the corresponding uplink data transmission power. The N power parameter packets and the L bundle correspond to each other in a certain order, or can have other correlations, which are indicated to the terminal device by the service node. In an embodiment, each beam is represented by one of: one reference signal; one carrier; or one spatial domain transmission resource; wherein the spatial domain transmission resource includes one of: an antenna port; a codebook; or a transport layer. In this embodiment, the service node generates different reference signals or different carriers. The generated carriers include armature carriers and non-armature carriers. The armature carriers are used to transmit narrowband primary synchronization signals, narrowband secondary synchronization signals, narrowband physical broadcast channels, narrowband system information blocks, or the like. Different beams can be distinguished by different correlated reference signals or different carriers. For example, the service node indicates the index values of different reference signals or different carriers to the terminal device to distinguish between different beams, thereby accurately indicating the power parameter packets of different beams. Alternatively, different beams can be distinguished by different spatial domain transmission resources.For example, different files correspond to different antenna ports, different codebooks or different transport layers. In an embodiment, configuration information is transmitted via one of the following signaling: broadcast messages; Radio Resource Controlling (RRC) signaling; Medium Access Control Element (MAC CE) signaling; or Downlink Control Information (DCI). Configuration information is transmitted via the above signaling, so that N power parameter packets can be efficiently indicated. In an embodiment, the power parameter package includes at least one of: a nominal power value; a partial power compensation factor; a downlink reference signal for path loss measurement; a downlink reference signal transmission power; or a power offset. In this embodiment, each power parameter packet includes at least one of: a nominal power value (PO_PUSCH); a partial power compensation factor ( ); a downlink reference signal transmission power (rs-power); a carrier power offset (rsPowerOffsetNonAnchor); or a downlink reference signal for path loss measurement. The terminal device may alternatively obtain these power parameters in other ways, for example, the power parameters are predefined in the protocol and therefore obtained directly, or the power parameters are obtained implicitly according to a mapping relationship between other information indicated by the service node and the defined power parameters. The terminal device may, based on the nominal power values corresponding to these power parameters, compensate the power and adjust the offset, and calculate the corresponding transmission power under the serving file in real time. Here, the downlink reference signals for path loss measurement under different beams are different or the same, but the corresponding transmission power or corrected power balancer is different. By preconfiguring and indicating the downlink reference signals for path loss measurement, the service node can determine which beam is the serving beam, providing a reliable basis for the terminal device to apply the corresponding power parameter package. In some embodiments, the service node may indicate a power parameter packet index to the terminal device via a System Information Block (SIB) or a Physical Broadcast Channel (PBCH), to instruct the terminal device to utilize a power parameter packet among N power parameter packets. In some embodiments, the service node indicates the carrier index value corresponding to the file via a bit field in the SIB. Different carriers are associated with different files. Therefore, the terminal device can determine the power balance of the armature or non-armature carriers on different beams according to the mapping between the carriers (index values) and the beams. In an embodiment, the method further includes step (130) or step (140). In step (130), the power update indication information is transmitted to the terminal device according to the serving file transfer information. In step (140), the power update indication information is transmitted to the terminal device according to the uplink measurement results. In this embodiment, a serving file is a file for data transmission between a service node and a terminal device, and serving file switching means that a serving file, in file L, used for data transmission is switched to another serving file. For example, in response to a serving file being switched from file 1 to file 2, the service node transmits power update indication information to the terminal device, to instruct the terminal device to use the power parameter packet associated with file 2 to calculate the transmission power in the case of serving file switching.Alternatively, in the case of serving beam switching, the service node shall perform measurement for the path loss of the uplink channel for the new serving beam (beam 2), and transmit, according to the uplink measurement results, power update indication information to the terminal device, so as to instruct the terminal device to adjust, in response to the change of path loss, the power parameter package used according to the actual situation. For example, given the partial power compensation factor in the power parameter package α=0.7 , the service node transmits the power update indication information to the terminal device according to the uplink measurement results of the path loss, and the terminal device can adjust the partial power compensation factor to α=1 accordingly. In embodiments, configuration information is also used to indicate the correlation between the power parameter packet N and the L bundle. In this embodiment, through configuration information, the service node can also indicate to the terminal device the correlation between the N power parameter packages and the L bundle, that is, indicate the correlation between the ith(1< i N) power parameter packages and the jth(1< j L) bundle, so that the terminal device can uniquely determine which power parameter packages to use under different serving bundles. In an embodiment, the method further includes step (101). In step (101), the first group indication information is transmitted, wherein the first group indication information includes group reference point information, and each group reference point corresponds to one group. In this embodiment, the terminal devices in the network are divided into at least one group, and then the configuration information is transmitted by the group, thereby saving signaling overhead and network resources, and improving the efficiency of indicating the power parameter packet. The service node transmits the first group indication information to the terminal device, so that the terminal device can determine the group to which the terminal device belongs according to the first group indication information, and determine, according to the indication of the configuration information, which power parameter packet should be used by the group to which the terminal device belongs. In this embodiment, the first group indication information includes group reference point information, which may be a location or terminal identifier of a terminal device considered as a group reference point. For example, there are a plurality of terminal devices in the network coverage area of a service node, where terminal device A, terminal device B, and terminal device C are used as group reference points, and the first group indication information includes the location of terminal device A, terminal device B, and terminal device C. The service node transmits the first group indication information to each target terminal device, so that the target terminal device can determine, according to the first group indication information, that it belongs to terminal device group A, terminal device group B, or terminal device group C.For example, if the target terminal device determines, according to the first group indication information received, that terminal device B is the terminal device in the reference point group closest to the target terminal device, the target terminal device determines that it belongs to terminal device group B. After receiving the configuration information, the target terminal device can utilize the power parameter package corresponding to terminal device group B to calculate the transmission power. In an embodiment, the method further includes step (102). In step (102), the second group indication information is transmitted, wherein the second group indication information includes region identifiers, and each region corresponds to one group. In this embodiment, the terminal devices in the network are divided into at least one group, and then the configuration information is transmitted by the group, thereby saving signaling overhead and network resources, and improving the efficiency of indicating the power parameter packet. The service node transmits the first and second group indication information to the terminal devices, so that the terminal devices can determine the group to which the terminal devices belong according to the second group indication information, and determine, according to the indication of the configuration information, which power parameter packet should be used by the group to which the terminal devices belong. In this embodiment, the second group indication information includes a region identifier. For example, the network coverage area of a service node is divided into region A, region B, and region C, and terminal devices in each region are grouped into the same group. The second group indication information includes a region identifier of region A, region B, or region C. The service node transmits the second group indication information to each target terminal device, so that the target terminal device can determine, according to the second group indication information, that it belongs to region group A, region group B, or region group C. For example, if the target terminal device determines, according to the received second group indication information, that it is in region B, the target terminal device determines that it belongs to region group B.After receiving the configuration information, the target terminal device can use the power parameter packet corresponding to the region group B to calculate the transmission power. In an embodiment, step 120 includes: transmitting, to each group, each power parameter packet associated with each group of terminal devices. In this embodiment, the service node transmits configuration information to each group according to the reference point of the group or region, to indicate the respective power parameter packets associated with each group, without transmitting the configuration information to each terminal device in the network coverage area, thereby saving signaling overhead and network resources and improving the efficiency of indicating the power parameter packets. Figure 2 is a schematic diagram of power control for a single beam of LEO satellites provided by an embodiment. As illustrated in Figure 2, a single beam of LEO satellites is moving, and the power control process includes the following steps. The service node configures the power parameter packages corresponding to different power control regions (region 1, region 2, region 3,..., region N) in the case of single-beam movement, where the path loss in the case of single-beam movement has a deviation. Before the beam moves to a certain region, the service node transmits configuration information (by group) to the terminal device, where the configuration information may include the index value of the power parameter package and various power parameters therein. The terminal device receives the configuration information and calculates the transmission power according to the power parameter packet indicated by the configuration information. The difference between the path loss in different regions can be adjusted by the partial power compensation factor α . Figure 3 is a schematic diagram of power control for a fixed beam of a LEO satellite provided by an embodiment. As illustrated in Figure 3, the beam is fixed during the movement of the LEO satellite, and the power control process includes the following steps. The service node pre-configures the beam power parameter packets in different directions (power parameter packet 1, power parameter packet 2,..., power parameter packet N). The service node transmits the first group indication information according to the satellite ephemeris and the trajectory motion of the group reference point, to indicate the location of the group reference point to the terminal device. The terminal device calculates the distance between the terminal device and each neighboring group reference point, and selects the nearest group reference point to determine the group to which the terminal device belongs. Before the beam changes its orientation, the service node transmits configuration information to each group via the SIB or PBCH, where the configuration information may include index values of power parameters set to distinguish between beams in different orientations. The terminal device receives the configuration information and calculates the transmission power according to the appropriate power parameter package used by the group to which the terminal device belongs. And the difference between the path losses in different directions can be adjusted by the partial power compensation factor α . Figure 4 is a schematic diagram of the power control for multi-beam switching of a LEO satellite provided by an embodiment. As shown in Figure 4, using multi-beam switching during the movement of a LEO satellite as an example, the power control process includes the following steps. The service node pre-configures different power parameter packages (power parameter package 1, power parameter package 2,..., power parameter package N), and different power parameter packages correspond to different files, which are distinguished by different operators. The service node broadcasts the index values of different carriers (Anchor or Non-Anchor) to the terminal devices via SIB or PBCH to distinguish between different beams. The service node transmits the first group indication information according to the satellite ephemeris and the trajectory motion of the reference point, to indicate the location of the group reference point to the terminal device. The terminal device calculates the distance between the terminal device and each neighboring group reference point, and selects the nearest group reference point to determine the group to which the terminal device belongs. Before the serving file transfer, the node service transmits configuration information to each group to indicate the power parameter package includes the nominal power value, partial power compensation factor, transmission power of the downlink reference signal, and the downlink reference signal for path loss measurement. The terminal device can obtain the power offset from the carrier (rs-PowerOffsetNonAnchor) by mapping the corresponding carrier index value. The terminal device, according to the group to which the terminal device belongs, receives the configuration information and calculates the transmission power to realize the power control of all groups under the serving beam switching. Figure 5 is a schematic diagram of power control for a single beam of a GEO satellite provided by an embodiment. As shown in Figure 5, using a single beam during the movement of a GEO satellite as an example, the coverage area of the beam is always fixed, and the power control process includes the following steps. The service node divides the beam coverage area into several regions, and transmits the region identifier to the terminal device in the corresponding region through the second group indication information. The service node broadcasts a reference signal, and indicates the power parameter packet to the terminal device through configuration information. The terminal device receives configuration information according to the group to which it belongs, and calculates the transmission power using the power parameter package corresponding to the region to which it belongs. The difference between the transmission power of different terminal devices can be adjusted by a partial power compensation factor α. The deviation of the terminal device power under the anchor carrier or the non-anchor carrier is adjusted by utilizing the power offset of the carrier (rs-PowerOffsetNonAnchor). Figure 6 is a schematic diagram of power control for GEO satellite multi-beam switching provided by an embodiment. As shown in Figure 6, using beam switching during GEO satellite movement as an example, the beam coverage area is always fixed, and the power control process includes the following steps. The service node pre-configures different power parameter packages (power parameter package 1, power parameter package 2,..., power parameter package N), and different power parameter packages correspond to different files. The service node generates different reference signals to distinguish between different files. The service node divides the beam coverage area into several regions, and transmits the region identifier to the terminal device in the corresponding region through the second group indication information. Before the presentation file transfer, the service node indicates the power parameter package to the terminal device through configuration information. The terminal device receives configuration information according to the group to which the terminal device belongs, and calculates the transmission power using the power parameter package corresponding to the region to which the terminal device belongs, so as to realize the power control of all groups under the serving beam switching. In the above embodiment, by pre-configuring and indicating the power parameters set under beam movement and beam switching, the service node can realize the indication and control of the transmission power of the terminal device, improve the flexibility of power control, and ensure communication quality. The service node generates different reference signals or broadcasts different carriers to distinguish between the beams, thereby accurately indicating the corresponding power parameter packets. According to the satellite ephemeris and the trajectory movement of the reference point, the service node broadcasts the group reference point or indicates the region identifier, to group the terminal device, and then performs power indication and control according to the group, thereby saving signaling overhead and improving the efficiency of power indication and control. In an embodiment of the present invention, a power control method is also provided, which is applied to a terminal device, for example, a user equipment (UE). It should be noted that, in this embodiment, the operations performed by the terminal device correspond one-to-one to the operations performed by the service node in the above embodiment, and reference may be made to any of the above embodiments for technical details not described in this embodiment. Figure 7 is a flowchart of a power control method provided by another embodiment. As shown in Figure 7, the method provided in this embodiment includes steps (210) and (220). In step (210), configuration information is received, which is used to indicate the N power parameter packages, where N is a positive integer. In step (220), the transmission power is determined according to the configuration information, and the uplink data is transmitted with the transmission power. In this embodiment, the service node preconfigures N power parameter packages, and indicates the packages to the terminal device through the configuration information of the N power parameter packages to provide a reliable basis for the selection and application of the terminal device in the case of different beams, different reference signals or different carriers. According to the indication of the configuration information, the terminal device uses the corresponding power parameter packages to calculate the transmission power, which can adapt to the movement or switching of the beam and realize flexible power control. In an embodiment, N power parameter packages are associated with L bundles, where L is a positive integer. In an embodiment, each beam is represented by one of: one reference signal; one carrier; or one spatial domain transmission resource; wherein the spatial domain transmission resource includes one of: an antenna port; a codebook; or a transport layer. In an embodiment, configuration information is received via one of the following signaling: broadcast messages; RRC signaling; CE MAC signaling; or DCI. In an embodiment, the power parameter package includes at least one of: a nominal power value; a partial power compensation factor; a downlink reference signal for path loss measurement; a downlink reference signal transmission power; or a power balancer. In an embodiment, the method further comprises step S230 or step S240. In step S230, the power update indication information is received and the transmission power is adjusted according to the power update indication information. In step S240, the transmission power is adjusted based on the power parameter packet associated with the serving file after switching according to the serving file switching information. In this embodiment, the serving file is a file for data transmission between the service node and the terminal device, and serving file switching means that the serving file, in the L file, used for data transmission is switched to another serving file. In the case of receiving power update indication information, the terminal device can update the transmission power by adjusting the parameters in the power parameter package (for example, the power compensation factor α is adjusted from 0.7 to 1). Alternatively, in the case of serving file switching, the terminal device can recalculate the transmission power using the power parameter package associated with the serving file after switching, so as to realize real-time transmission power update and adjustment, improve the flexibility and reliability of power control, and ensure the quality of data transmission. In an embodiment, the method further includes step S211. In step S211, the correlation between the power parameter packet N and the beam L is determined according to the configuration information. In an embodiment, the method further includes steps S250 and S251. In step S250, the first group indication information is received, where the first group indication information includes group reference point information, and each group reference point corresponds to one group. In step S251, the group to which the terminal device belongs is determined according to the first group indication information. In this embodiment, a terminal device can determine the group to which the terminal device belongs according to the first group indication information, and determine, according to the indication from the configuration information, which power parameter package should be used by the group to which the terminal device belongs. For example, the terminal device can determine the nearest group reference point according to the first group indication information, and use the group corresponding to the group reference point as the group to which the terminal device belongs. Then, the terminal device can determine the power parameter set to be used from the configuration information according to the group, and the service node does not need to indicate the power parameter package to each terminal device, thereby effectively reducing the signaling overhead and improving the efficiency of power indication and control. In an embodiment, the method further comprises steps S260 and S261. In step S260, the second group indication information is received, where the second group indication information includes region identifiers, and each region corresponds to one group. In step S261, the group to which the terminal device belongs is determined according to the second group indication information. In this embodiment, a terminal device can determine the group to which the terminal device belongs according to the second group indication information, and determine, according to the indication from the configuration information, which power parameter package should be used by the group to which the terminal device belongs. For example, a terminal device can determine, according to the second group indication information, a region to which the terminal device belongs, and use a group corresponding to that region as the group to which the terminal device belongs. Then, the terminal device can determine the power parameter set to be used from the configuration information according to the group, and the service node does not need to indicate the power parameter package to each terminal device, thereby effectively reducing signaling overhead and improving the efficiency of power indication and control. In an embodiment, the method further comprises step S270. In step S270, a power parameter packet, in the configuration information, associated with the group to which the terminal device belongs is determined according to the group to which the terminal device belongs.
