[0036] The present application is described below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. It should also be noted that, for ease of description, only the parts related to the present application rather than all structures are shown in the accompanying drawings.

[0037] In the NTN system, satellites are mobile, and the coverage area of ​​beams or cells moves with the movement of satellites. The beams are constantly moving or switching, which causes the link quality of the uplink signal sent by the terminal to change continuously, and the influence of different types of satellite beams on the link quality is also different. Since the terminal's transmit power cannot dynamically adapt to the moving or switching beams and the power control flexibility is poor, the communication quality and reliability are seriously affected. In this embodiment, the service node preconfigures a power parameter set and indicates it to the terminal in response to the beam movement and switching in NTN, and on this basis, flexible indication and control of the terminal transmit power is achieved.

[0038] Figure 1 FIG. 1 is a flow chart of a power control method provided by an embodiment. The power control method can be applied to a service node, for example, a base station. Figure 1 As shown, the method provided in this embodiment includes step 110 and step 120.

[0039] In step 110, configuration information is sent, where the configuration information is used to indicate N groups of power parameter sets, where N is a positive integer.

[0040] In step 120, uplink data is received, and the transmission power of the uplink data is determined by the terminal according to the configuration information.

[0041] In this embodiment, the service node preconfigures N sets of power parameter sets and indicates them to the terminal through configuration information. These N sets of power parameter sets are selected and applied by the terminal under different reference signals or beams associated with carriers as the basis for calculating the uplink data transmission power. In the process of indicating the N sets of power parameter sets, the correspondence between the N sets of power parameter sets and different beams, different reference signals or different carriers can also be indicated. For example, the first set of power parameter sets corresponds to the first beam, and the second set of power parameter sets corresponds to the second beam. In the case where the terminal uses the first beam (the first beam is used as the service beam) to send uplink data, the corresponding transmit power on the first beam can be calculated based on the first set of power parameter sets; in the case where the terminal uses the second beam (the second beam is used as the service beam) to send uplink data, the corresponding transmit power on the second beam can be calculated based on the second set of power parameter sets. In addition, if the service beam switching occurs, for example, the service beam is switched from the first beam to the second beam, the terminal can also change the adopted power parameter set according to the indication of the configuration information to accurately calculate the transmit power and adapt to the movement or switching of the beam.

[0042] The service node indicates the pre-configured power parameter set to the terminal through configuration information, providing a basis for the terminal to calculate the transmit power. On this basis, it realizes flexible indication and control of the terminal transmit power and improves the reliability of power control.

[0043] In one embodiment, N groups of power parameters are associated with L beams, where L is a positive integer.

[0044] In this embodiment, there is an association relationship between the N groups of power parameters and the L beams. Among the L beams, the one used to transmit uplink data is the service beam. The terminal can select a corresponding set of power parameters according to the service beam, and calculate the transmission power of the uplink data accordingly. The N groups of power parameters and the L beams can correspond to each other in a certain order, or have other associations, and are indicated to the terminal by the service node.

[0045] In one embodiment, each beam is represented by one of the following: a reference signal; a carrier; a spatial transmission resource; wherein the spatial transmission resource includes one of the following: an antenna port; a codebook; a transmission layer.

[0046] In this embodiment, the service node generates different reference signals or different carriers, wherein the generated carriers may include anchor carriers (Anchor Carrier) and non-anchor carriers (Non-Anchor Carrier), and the anchor carrier is used to send narrowband primary synchronization signals, narrowband secondary synchronization signals, narrowband physical broadcast channels or narrowband system information blocks, etc. Different beams can be distinguished by different associated reference signals or different carriers. For example, the service node indicates the index values ​​of different reference signals or different carriers to the terminal to distinguish different beams, thereby achieving accurate indication of power parameter sets for different beams. Different beams can also be distinguished by different spatial transmission resources. For example, different beams correspond to different antenna ports, different codebooks or different transmission layers.

[0047] In one embodiment, the configuration information is sent through one of the following signaling: broadcast message; Radio Resource Control (RRC) signaling; Medium Access Control, Control Element (MAC CE) signaling; Downlink Control Information (DCI). By sending the configuration information through the above signaling, efficient indication of N sets of power parameter sets is achieved.

[0048] In one embodiment, the power parameter set includes at least one of the following: a power reference value; a partial power compensation factor; a downlink reference signal for measuring path loss; a downlink reference signal transmission power; and a power offset.

[0049] In this embodiment, each power parameter set may include one or more of the following parameters: power reference value (PO_PUSCH); partial power compensation factor (α); downlink reference signal transmit power (rs-power); carrier power offset (rs-PowerOffsetNonAnchor); downlink reference signal for measuring path loss. The terminal may also obtain these power parameters in other ways, such as those predefined in the protocol, implicitly obtained based on the mapping relationship between other information indicated by the service node and the power parameter set, etc. Based on these power parameters, the terminal may compensate the power, adjust the offset, etc. on the basis of the power reference value, and calculate the corresponding transmit power under the service beam in real time.

[0050] Among them, under different beams, the downlink reference signal used to measure the path loss may be different, or it may be the same, but the corresponding transmit power or fixed power offset is different. The service node can specify which beam is used as the service beam by pre-configuring and indicating the downlink reference signal used to measure the path loss, providing a reliable basis for the terminal to apply the corresponding power parameter set.

[0051] In some embodiments, the service node may indicate the index of the power parameter set to the terminal via a system information block (SIB) or a physical broadcast channel (PBCH), thereby indicating which power parameter set the terminal needs to adopt from among N power parameter sets.

[0052] In some embodiments, the service node can indicate the carrier index value corresponding to the beam through the bit field in the SIB. Different carriers are associated with different beams. Therefore, the terminal can determine the power offset value of the Anchor or Non-Anchor carrier on different beams based on the mapping between the carrier (index value) and the beam.

[0053] In one embodiment, it further includes:

[0054] Step 130: Send power update indication information to the terminal according to the serving beam switching information; or,

[0055] Step 140: Send power update indication information to the terminal according to the uplink measurement result.

[0056] In this embodiment, the service beam may be a beam used for data transmission between the service node and the terminal, and the service beam switching refers to the switching of the service beam used for data transmission among the L beams. For example, if the service beam is switched from beam 1 to beam 2, the service node sends power update indication information to the terminal to indicate that the terminal should apply the power parameter set associated with beam 2 to calculate the transmit power when the service beam is switched. Alternatively, in the case of service beam switching, the service node measures the path loss of the uplink channel for the new service beam (beam 2), and sends power update indication information to the terminal based on the uplink measurement result to indicate that the terminal needs to adjust the adopted power parameter set according to the actual situation when the path loss changes. For example, the partial power compensation factor α in the power parameter set is 0.7, and the service node sends power update indication information to the terminal based on the uplink measurement result of the path loss, and the terminal can adjust the partial power compensation factor to α=1 accordingly.

[0057] In one embodiment, the configuration information is also used to indicate the association relationship between N groups of power parameters and L beams.

[0058] In this embodiment, the service node can also indicate to the terminal through configuration information the association relationship between N groups of power parameters and L beams, that is, the association relationship between the i-th (1≤i≤N) group of power parameter sets and the j-th (1≤j≤L) beam, so that the terminal can uniquely determine which group of power parameter sets to use under different service beams.

[0059] In one embodiment, it further includes:

[0060] Step 101: Send first grouping indication information, where the first grouping indication information includes grouping reference point information, and each grouping reference point corresponds to a group.

[0061] In this embodiment, the terminals in the network can be divided into one or more groups, and then the configuration information is sent according to the groups, thereby saving signaling overhead and network resources and improving the efficiency of indicating the power parameter set. The service node sends the first group indication information to the terminal, and the terminal can determine the group to which it belongs according to the first group indication information, and determine which set of power parameter sets should be used for the group to which it belongs according to the indication of the configuration information.

[0062] In this embodiment, the first grouping indication information includes grouping reference point information, and the grouping reference point information is, for example, the location of the terminal serving as the grouping reference point, the terminal identifier, etc. For example, there are multiple terminals within the coverage of the service node network, wherein terminal A, terminal B, and terminal C serve as grouping reference points, and the first grouping indication information includes the locations of terminal A, terminal B, and terminal C. The service node sends the first grouping indication information to each target terminal, and the target terminal can determine that it belongs to the group of terminal A, the group of terminal B, or the group of terminal C. For example, the target terminal determines that the terminal closest to the grouping reference point is terminal B according to the received first grouping indication information, and the target terminal determines that it belongs to the group of terminal B; after receiving the configuration information, the target terminal can use the power parameter set corresponding to the group of terminal B to calculate the transmit power.

[0063] In one embodiment, it further includes:

[0064] Step 102: Send second grouping indication information, where the second grouping indication information includes an area identifier, and each area corresponds to a group.

[0065] In this embodiment, the terminals in the network can be divided into one or more groups, and then the configuration information is sent according to the groups, thereby saving signaling overhead and network resources and improving the efficiency of indicating the power parameter set. The service node sends the second group indication information to the terminal, and the terminal can determine the group to which it belongs according to the second group indication information, and determine which set of power parameter sets should be used for the group to which it belongs according to the indication of the configuration information.

[0066] In this embodiment, the second grouping indication information includes an area identifier. For example, the network coverage of the service node is divided into area A, area B, and area C, and the terminals in each area are divided into the same group. The second grouping indication information includes the area identifier of area A, area B, or area C. The service node sends the second grouping indication information to each target terminal, and the target terminal can determine that it belongs to the group of domain A, area B, or area C. For example, the target terminal determines that it is in area B based on the received second grouping indication information, and the target terminal determines that it belongs to the group of area B; after receiving the configuration information, the target terminal can use the power parameter set corresponding to the group of area B to calculate the transmission power.

[0067] In one embodiment, step 120 specifically includes: sending a power parameter set associated with the corresponding group to each of the groups respectively.

[0068] In this embodiment, the service node sends configuration information to each group according to the group reference point or area, thereby indicating the power parameter set associated with each group, without sending configuration information to each terminal within the network coverage area, thereby saving signaling overhead and network resources and improving the efficiency of indicating the power parameter set.

[0071] Before the beam moves to a specific area, the service node sends configuration information to the terminal (in groups), and the configuration information may include the index value of the power parameter set and various power parameters;

[0093] The service node divides the beam coverage into multiple areas, and sends the area identifier to the terminal in the corresponding area through the second grouping indication information;

[0094] Before the serving beam is switched, the serving node indicates the power parameter set to the terminal through configuration information;

[0095] The terminal receives configuration information according to the group, and calculates the transmission power using the power parameter set corresponding to the area to which it belongs, thereby achieving power control of all groups under service beam switching.

[0098] Figure 7 A flowchart of a power control method provided in another embodiment is shown in FIG. Figure 7 As shown, the method provided in this embodiment includes step 210 and step 220.

[0099] In step 210, configuration information is received, where the configuration information is used to indicate N groups of power parameter sets, where N is a positive integer.

[0100] In step 220, the transmit power is determined according to the configuration information, and uplink data is sent according to the transmit power.

[0101] In this embodiment, the service node preconfigures N sets of power parameter sets and indicates them to the terminal through configuration information.

[0109] In this embodiment, the service beam may be a beam used for data transmission between the service node and the terminal, and the service beam switching refers to the switching of the service beam used for data transmission among the L beams. When the terminal receives the power update indication information, it may update the transmit power by adjusting the parameters in the power parameter set (for example, adjusting the power compensation factor α from 0.7 to 1); or, when the service beam switching occurs, the transmit power may be recalculated using the power parameter set associated with the switched service beam, thereby realizing real-time update and adjustment of the transmit power, improving the flexibility and reliability of power control, and ensuring the quality of data transmission.

[0115] In this embodiment, the terminal can determine the group to which it belongs according to the first group indication information, and determine which set of power parameter sets should be used for the group to which it belongs according to the indication of the configuration information. For example, the terminal can determine the closest group reference point according to the first group indication information, and use the group corresponding to the group reference point as the group described by itself. On this basis, it can determine which set of power parameter sets to use from the configuration information according to the group, and the service node does not need to indicate the power parameter set to each terminal, which effectively reduces the signaling overhead and improves the efficiency of indication and power control.

For example, the terminal can determine the area in which it is located according to the second group indication information, and use the group corresponding to the area as the group described by itself. On this basis, it can determine which set of power parameter sets to use from the configuration information according to the group.
