[0055] Optionally, the terminal device can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; can be deployed on the water surface (such as ships, etc.); can be deployed in the air (such as airplanes, balloons and satellites, etc.).

[0056] Optionally, the terminal device may include a device with wireless communication function, such as a chip system, a chip, or a chip module. For example, the chip system may include a chip and may also include other discrete devices.

[0057] Optionally, the terminal device of the embodiment of the present application can be a chip, a chip module, a device, a unit, etc., and there is no specific limitation on this.

[0059] A network device may be a device with transceiver functions and may be used to communicate with a terminal device.

[0060] Optionally, the network device may be responsible for radio resource management (RRM), quality of service (QoS) management, data compression and encryption, data transmission and reception, etc. on the air interface side.

[0061] Optionally, the network device may include a base station (BS) in a communication system or a device deployed in a radio access network (RAN) for providing wireless communication functions, that is, the network device may include a device in the RAN.

[0062] For example, the devices in the RAN may include an evolved node B (eNB or eNodeB) in an LTE communication system, a next generation evolved node B (ng-eNB) in an NR communication system, a next generation node B (gNB) in an NR communication system, a master node (MN) in a dual-connection architecture, a second node or secondary node (SN) in a dual-connection architecture, etc., without specific limitation.

[0063] Optionally, the network device may include a device in a core network (CN).

Furthermore, in other embodiments, the network device may also include an active antenna unit (AAU). The CU implements a portion of the network device's functions, while the DU implements another portion of the network device's functions.

In addition, the AAU may implement some physical layer processing functions, RF processing, and related functions of the active antenna. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this network deployment, high-layer signaling (such as RRC signaling) can be considered to be generated by the CU and sent by the DU, or sent jointly by the DU and AAU. It is understood that network devices may include at least one of the CU, DU, and AAU. Furthermore, the CU may be classified as a RAN device, or as a core network device, without specific limitation.

[0073] Optionally, the network device described in the embodiments of the present application may be a chip, a chip module, a device, a unit, etc., and there is no specific limitation on this.

[0074]

NTN system

[0075] The technical solutions of the embodiments of the present application can be applied to NTN systems, for example, satellite communication systems. In satellite communication systems, network devices usually communicate with ground terminal devices via satellites.

[0076] Currently, 5G NR has entered the commercial deployment phase after moving from standardization. The NR standard was designed based on the characteristics of terrestrial communications and provides high-speed, high-reliability, and low-latency communications for user terminals. Compared to terrestrial communication systems, NTN systems offer a wider coverage area and flexible networking.

[0077] The NTN system utilizes equipment such as drones, high-altitude platforms (HAPS), and satellites to form a network, providing data transmission, voice communication, and other services to terminal devices. High-altitude platform equipment typically operates at an altitude of 8 to 50 km above the ground. Satellite communication systems can be categorized into three types based on the satellite's orbital altitude: geostationary Earth orbit (GEO) satellite communication systems, also known as synchronous orbit satellite systems; medium Earth orbit (MEO) satellite communication systems; and low Earth orbit (LEO) satellite communication systems.

[0078] A satellite may be a spacecraft that is a transmitter of a transparent payload (also known as a bent pipe payload) or a regenerative payload signal, that is, a transparent satellite or a regenerative satellite.

[0079] Satellites can be divided into transparent (also known as bent pipe payload) mode and regenerative mode according to their operating mode or payload.

[0080] When the satellite works in transparent transmission mode, it is a spacecraft that is a transmitter of transparent transmission payload signals and has the function of relaying and forwarding.

[0081] When the satellite operates in regeneration mode, it has data processing capabilities, base station (such as gNB) functions or partial base station functions. At this time, the satellite can be regarded as a base station.

[0082] It should be noted that satellites can be divided into GEO satellites, MEO satellites, LEO satellites and high elliptical orbit (HEO) satellites according to the different orbital altitudes.

[0083] The orbital altitude of GEO satellite is 35786km. Its main advantage is that it can remain stationary relative to the ground and provide a large coverage area.

[0084] However, GEO satellite communications also have obvious disadvantages:

[0085] 1) GEO satellite orbits are far from the Earth, resulting in high free-space propagation losses, which limits the communication link budget. To increase transmit / receive gain, satellites need to be equipped with larger antennas.

[0086] 2) The communication transmission delay is large, reaching a round-trip delay of around 500ms, which cannot meet the needs of real-time services;

[0087] 3) GEO orbital resources are relatively limited, launch costs are high, and it cannot provide coverage for the Earth's polar regions.

[0088] MEO satellites orbit at altitudes between 2,000 and 35,786 km. Their advantage is that they can achieve global coverage with a relatively small number of satellites. However, their orbital altitude is higher than that of LEO satellites, and transmission latency is still greater than that of LEO satellite communications. Considering the advantages and disadvantages of MEO satellite communications, MEO satellites are primarily used for positioning and navigation.

[0089] LEO satellites operate at orbital altitudes between 300 and 2000 km. These altitudes are lower than those of MEO and GEO satellites, offering advantages such as reduced data transmission latency, minimal transmission loss, and relatively low launch costs. Consequently, LEO satellite communications have garnered widespread attention in recent years.

[0090] The orbital altitude of HEO satellites ranges from 400km to 50,000km.

[0091] A non-terrestrial network gateway (NTN gateway), which can be an earth station or gateway located on the ground, provides sufficient radio frequency (RF) power and RF sensitivity to connect ground-based equipment (such as network equipment) with satellites. The NTN gateway is a node in the transport network layer (TNL).

[0092] For example, an NTN system according to an embodiment of the present application is as follows: Figure 2As shown in FIG. NTN communication system 20 may include terminal device 210, satellite 230, non-terrestrial network gateway 240, and network device 250. Terminal device 210, non-terrestrial network gateway 240, and network device 250 may be located on the surface of the Earth, while satellite 230 is located in Earth orbit. Satellite 230 may provide communication services to the geographic area covered by its signal and may communicate with terminal device 210 located within its signal coverage area.

[0093] In addition, terminal device 210 is located within the coverage area of a beam or a cell, and the coverage area of the beam or the cell includes a reference point 220. Furthermore, the communication link between terminal device 210 and satellite 230 is called a service link. The communication link between satellite 230 and non-terrestrial network gateway 240 is called a feeder link.

[0094] It should be noted that the non-terrestrial network gateway 240 and the network device 250 can be integrated into the same device or can be independent devices, and there is no specific limitation on this.

[0095] Beam Hopping

[0096] Beam-hopping (BH) is a new communication technology based on adaptive beamforming, significantly different from traditional fixed-beam communication methods. For satellite communications, this technology operates through time division, dynamically adjusting the direction of the satellite beam based on service demands within the satellite's coverage area. This is done to rationally allocate beam resources and ensure that the maximum traffic demand can be met in different areas. Specifically, when traffic in a region is high, more time slots are allocated to support communications in that area; when traffic is low, beam time slots in that area are correspondingly reduced, thereby improving resource utilization efficiency across the entire system.

[0097] Synchronization Signal Block (SSB)

[0098] The SSB is a physical signal block used for cell identification, time synchronization, and frequency offset compensation. In the 5G NR system, each cell periodically broadcasts SSBs. The UE receives and decodes these SSBs to obtain information such as the current cell ID, clock, and frequency synchronization.

[0099] The SSB power configuration can be based on the transmit power level used when broadcasting the SSB in each cell. This ensures that the terminal device can accurately detect and identify the cell in which it is located, and establish correct clock and frequency synchronization. The downlink SSB per resource unit power (Energy Per Resource Element, EPRE) can be given by the parameter ss-PBCH-BlockPower provided by the upper layer. The downlink secondary synchronization signals (SSS) transmit power is defined as the linear average of the power contributions (in W) of all resource elements carrying the SSS within the operating bandwidth.

[0100] Channel State Information Reference Signal (CSI-RS)

[0101] CSI-RS is a reference signal used to measure and estimate channel state information. UEs can use received CSI-RS signals to assess wireless channel quality and perform adaptive modulation and coding based on this feedback. CSI-RS can also be used for advanced technical solutions such as beamforming and interference mitigation.

[0102] The downlink CSI-RS EPRE can be derived from the SSB downlink transmit power given by the parameter ss-PBCH-BlockPower and the CSI-RS power offset given by the parameter powerControlOffsetSS provided by the higher layer. The CSI-RS power offset represents the power offset value of the CSI-RS resource unit relative to the SSB resource unit in dB. The downlink reference signal transmit power is defined as the linear average of the power contribution (unit W) of the resource elements carrying the configured CSI-RS within the operating bandwidth.

[0103] Physical Downlink Shared Channel (PDSCH)

[0104] PDSCH is a physical channel that carries downlink data transmission.

[0105] The downlink PDSCH EPRE can be derived from the SSB downlink transmit power given by the parameter ss-PBCH-BlockPower provided by the upper layer, the CSI-RS power offset given by the parameter powerControlOffsetSS provided by the upper layer, and the PDSCH power offset given by the parameter powerControlOffset provided by the upper layer. The PDSCH power offset represents the power offset value of the PDSCH resource unit relative to the non-zero state (Non Zero Power, NZP) CSI-RS resource unit in dB, that is, the power ratio of the demodulation reference signal (DMRS) / CSI-RS.

[0106] The following embodiment specifically illustrates how to adjust downlink signal / channel transmit power using beam hopping technology through the following schemes. These schemes may be related to or independent of each other, and the same contents between different schemes may be referenced by each other, which is not described in detail here.

[0107] [Scheme 1]

[0108] a. Description

[0109] In "Solution 1," a terminal device or network device obtains beam information, which indicates the beams within a cell. The terminal device or network device then adjusts the SSB transmission power based on the beam information.

[0110] In some examples, beam information can be used to indicate that some beams are activated within the cell.

[0111] Below, this application explains the beam information from the following three situations.

[0112] First case:

[0113] In the first case, the beam information includes that half of the beams in the cell are activated. Thus, when the terminal device or network device obtains the beam information, the terminal device or network device increases the SSB transmission power by 3dB.

[0114] For example, in Figure 3 In Cell A, there are eight beams. For easy identification, the eight beams are numbered 0, 1, 2, 3, 4, 5, 6, and 7. The standard SSB power for each beam is configured using the parameter ss-PBCH-BlockPower provided by higher layers. If beams 0-3 are currently activated in Cell A and beams 4-7 are activated at a later time, the number of active beams in the cell at each moment is half the number of beams in the cell. The terminal device or network equipment increases the SSB transmit power by 3 dB.

[0115] Second case:

[0116] In the second case, the beam information includes M beams activated in the cell. Thus, when the terminal device or network device obtains the beam information, the terminal device or network device increases the SSB transmission power by X dB.

[0117] Among them, the SSB transmission power is directly configured by the parameter ss-PBCH-BlockPower provided by the upper layer. For example, if the parameter ss-PBCH-BlockPower provided by the upper layer is 20, the SSB transmission power is 20dB; then, when the terminal device or network device obtains the beam information, the terminal device or network device increases the SSB transmission power by XdB, so that the SSB transmission power changes from 20dB to 20+XdB.

[0118] Where M is a positive integer, and the value of X is determined according to the total number of beams in the cell and the value of M.

[0119] For example, the value of X satisfies the following formula:

[0120] X = 101gN / M;

[0121] Where N represents the total number of beams in the cell.

[0122] The third case:

[0123] In the third case, the beam information includes the currently activated beam combination. Thus, when the terminal device or network device obtains the beam information, it determines the current SSB transmit power adjustment value based on the currently activated beam combination and the first mapping relationship, and then increases the SSB transmit power by the current SSB transmit power adjustment value.

[0124] For example, as shown in Table 1, different beam combinations correspond to different SSB transmit power adjustment values. If the beam information includes currently activated beams 0-3 in cell A, and the beam combination in Table 1 is beams 0-3, the SSB transmit power adjustment value is 0, and the terminal device or network device does not change the SSB transmit power.

[0125] Table 1

[0126]

[0127]

[0128] b. Mapping relationship

[0129] When a terminal device or network device obtains partial beam activation information and obtains the currently activated beam combination, it needs to determine the transmit power adjustment value of the currently activated beam combination. Therefore, in order to determine the SSB transmit power adjustment values corresponding to different activated beam combinations, this application introduces a "first mapping relationship." The first mapping relationship can be a table of different activated beam combinations and their corresponding SSB transmit power adjustment values, or a function or equation for different activated beam combinations, or can also be referred to as a "mapping rule," "mapping method," "corresponding relationship," "configuration table," and the like.

[0130] In this way, for different activation beam combinations, the terminal device or network device can determine the adjustment value of the current SSB transmission power, thereby adjusting the SSB transmission power.

[0131] [Scheme 2]

[0132] a. Description

[0133] The terminal device or network device obtains beam information, which is used to indicate the beam in the cell, and then adjusts the CSI-RS transmission power according to the beam information.

[0134] In some examples, beam information can be used to indicate that some beams are activated within the cell.

[0135] The following four scenarios describe the beam information:

[0136] First case:

[0137] In the "first case", the beam information includes that half of the beams in the cell are activated. In this way, when the terminal device or the network device obtains the first beam partial activation information, the terminal device or the network device increases the CSI-RS transmission power by 3dB.

[0138] For example, in Figure 3 In cell A, there are eight beams. For easy identification, the eight beams are numbered 0, 1, 2, 3, 4, 5, 6, and 7. The standard CSI-RS transmit power for each beam is configured using the ss-PBCH-BlockPower and powerControlOffsetSS parameters provided by higher layers. If beams 0-3 are currently activated in cell A and beams 4-7 are activated at a later time, the number of active beams in the cell at each moment is half the number of beams in the cell. The terminal device or network equipment increases the SSB transmit power by 3 dB.

[0139] Second case:

[0140] In the second case, the beam information includes M beams activated in the cell. Thus, when the terminal device or network device obtains the beam information, the terminal device or network device increases the CSI-RS transmit power by X dB.

[0141] The SSB transmit power is directly configured by the parameter ss-PBCH-BlockPower provided by the upper layer. For example, if the parameter ss-PBCH-BlockPower provided by the upper layer is 20, the SSB transmit power is 20dB. The CSI-RS transmit power offset is directly configured by the parameter powerControlOffsetSS provided by the upper layer. For example, if the parameter powerControlOffsetSS provided by the upper layer is 10, the CSI-RS transmit power offset is 10dB. At this time, the CSI-RS transmit power is 20dB + 10dB = 30dB. Then, when the terminal device or network device obtains the beam information, the terminal device or network device increases the CSI-RS transmit power by XdB, so that the CSI-RS transmit power changes from 30dB to 30 + XdB.

[0142] Where M is a positive integer, and the value of X is determined according to the total number of beams in the cell and the value of M.

[0143] For example, the value of X satisfies the following formula:

[0144] X = 101gN / M;

[0145] Where N represents the total number of beams in the cell.

[0146] The third case:

[0147] In the third case, the beam information includes the currently activated beam combination. Thus, when the terminal device or network device obtains the beam information, it determines the current CSI-RS transmit power offset adjustment value based on the currently activated beam combination and the second mapping relationship, and then increases the CSI-RS transmit power by the current CSI-RS transmit power offset adjustment value.

[0148] For example, as shown in Table 2, different beam combinations correspond to different CSI-RS transmit power offset adjustment values. If the beam information includes currently activated beams 0-3 in cell A, and the beam combination in Table 2 is beams 0-3, the CSI-RS transmit power offset adjustment value is 0, and the terminal device or network device does not change the CSI-RS transmit power.

[0149] Table 2

[0150] CSI-RS transmit power offset adjustment value (dB) Beam combining 0 Beam 0, 1, 2, 3 0 Beams 4, 5, 6, 7 +3 Beam 0, 1 +3 Beam 2, 3 +4 Beam 4, 5 +4 Beam 6, 7

[0151] The fourth case:

[0152] In the "fourth case", the beam information includes the currently activated beam combination. When the terminal device or the network device obtains the beam information, the terminal device or the network device determines the adjustment value of the current SSB transmit power and the adjustment value of the current CSI-RS transmit power offset based on the currently activated beam combination and the third mapping relationship, and then increases the SSB transmit power by the adjustment value of the current SSB transmit power and the adjustment value of the current CSI-RS transmit power offset.

[0153] For example, as shown in Table 3, different beam combinations correspond to different CSI-RS transmit power offset adjustment values and SSB transmit power adjustment values. If the beam information includes currently activated beams 0-3 in cell A, and the beam combination in Table 3 is beams 0-3, the CSI-RS transmit power offset adjustment value is 0, the SSB transmit power adjustment value is 0, and the terminal device or network device does not change the CSI-RS transmit power.

[0154] Table 3

[0155]

[0156] b. Mapping relationship

[0157] When a terminal device or network device obtains partial beam activation information and obtains the currently activated beam combination, it needs to determine the transmit power adjustment value of the currently activated beam combination. Therefore, in order to determine the SSB transmit power adjustment values corresponding to different activated beam combinations, this application introduces a "second mapping relationship" and a "third mapping relationship." The second mapping relationship and the third mapping relationship can be a table of different activated beam combinations and their corresponding SSB transmit power adjustment values, or a function or equation for different activated beam combinations, or can be referred to as a "mapping rule," "mapping method," "corresponding relationship," "configuration table," and the like.

[0158] In this way, for different activation beam combinations, the terminal device or network device can determine the adjustment value of the current SSB transmit power and the adjustment value of the current CSI-RS transmit power offset, thereby adjusting the CSI-RS transmit power.

[0159] [Scheme 3]

[0160] a. Description

[0161] The terminal device or network device obtains beam information, which is used to indicate the beam in the cell, and then adjusts the transmit power of the PDSCH according to the beam information.

[0162] In some examples, beam information can be used to indicate that some beams are activated within the cell.

[0163] The following four scenarios describe the beam information:

[0164] First case:

[0165] In the first case, the beam information includes that half of the beams in the cell are activated. Thus, when the terminal device or network device obtains the beam information, the terminal device or network device increases the PDSCH transmit power by 3dB.

[0166] For example, in Figure 3 In cell A, there are eight beams. For easy identification, the eight beams are numbered 0, 1, 2, 3, 4, 5, 6, and 7. The standard PDSCH transmit power for each beam is configured by the parameters ss-PBCH-BlockPower, powerControlOffsetSS, and powerControlOffset, provided by higher layers. If beams 0-3 are currently activated in cell A and beams 4-7 are activated at a later time, the number of active beams in the cell at each moment is half the number of beams in the cell. The terminal device or network equipment increases the PDSCH transmit power by 3 dB.

[0167] Second case:

[0168] In the second case, the beam information includes M beams activated in the cell. Thus, when the terminal device or network device obtains the beam information, the terminal device or network device increases the transmit power of the PDSCH by X dB.

[0169] The SSB transmit power is directly configured by the parameter ss-PBCH-BlockPower provided by the higher layers. For example, if the parameter ss-PBCH-BlockPower provided by the higher layers is 20, the SSB transmit power is 20dB. The CSI-RS transmit power offset is directly configured by the parameter powerControlOffsetSS provided by the higher layers. For example, if the parameter powerControlOffsetSS provided by the higher layers is 10, the CSI-RS transmit power offset is 10dB. The PDSCH transmit power offset is directly configured by the parameter powerControlOffset provided by the higher layers. For example, if the parameter powerControlOffsetSS provided by the higher layers is 5, the PDSCH transmit power offset is 5dB. At this point, the PDSCH transmit power is 20dB + 10dB + 5dB = 35dB. Then, when the terminal device or network device obtains beam information, it increases the PDSCH transmit power by XdB, increasing the PDSCH transmit power from 35dB to 35 + XdB.

[0170] Where M is a positive integer, and the value of X is determined according to the total number of beams in the cell and the value of M.

[0171] For example, the value of X satisfies the following formula:

[0172] X = 101gN / M;

[0173] Where N represents the total number of beams in the cell.

[0174] The third case:

[0175] In the third case, the beam information includes the currently activated beam combination. Thus, when the terminal device or network device obtains the beam information, it determines the current PDSCH transmit power offset adjustment value based on the currently activated beam combination and the fourth mapping relationship, and then increases the PDSCH transmit power by the current PDSCH transmit power offset adjustment value.

[0176] For example, as shown in Table 4, different beam combinations correspond to different PDSCH transmit power offset adjustment values. If the beam information includes currently activated beams 0-3 in cell A, and the beam combination in Table 4 is beams 0-3, the PDSCH transmit power offset adjustment value is 0, and the terminal device or network device does not change the PDSCH transmit power.

[0177] Table 4

[0178] PDSCH transmit power offset adjustment value (dB) Beam combining 0 Beam 0, 1, 2, 3 0 Beams 4, 5, 6, 7 +3 Beam 0, 1 +3 Beam 2, 3 +4 Beam 4, 5 +4 Beam 6, 7

[0179] The fourth case:

[0180] In the "fourth case", the beam information includes the currently activated beam combination. In this way, when the terminal device or network device obtains the beam information, the terminal device or network device determines the adjustment value of the current SSB transmit power, the adjustment value of the current CSI-RS transmit power offset, and the adjustment value of the current PDSCH transmit power offset based on the currently activated beam combination and the fifth mapping relationship, and then increases the SSB transmit power by the adjustment value of the current SSB transmit power, the adjustment value of the current CSI-RS transmit power offset, and the adjustment value of the current PDSCH transmit power offset.

[0181] For example, as shown in Table 5, different beam combinations correspond to different CSI-RS transmit power offset adjustment values, SSB power adjustment values, and PDSCH transmit power offset adjustment values. If the beam information includes currently activated beams 0 and 1 in cell A, and the beam combination in Table 5 is beams 0 and 1, the CSI-RS transmit power offset adjustment value is +1dB, the SSB power adjustment value is +1dB, and the PDSCH transmit power offset adjustment value is +1dB. The terminal device or network device increases the PDSCH transmit power by +1+1+1=+3dB.

[0184]

[0185] b. Mapping relationship

[0186] When a terminal device or network device obtains partial beam activation information and obtains the currently activated beam combination, it needs to determine the transmit power adjustment value of the currently activated beam combination. Therefore, in order to determine the SSB transmit power adjustment values corresponding to different activated beam combinations, this application introduces a "fourth mapping relationship" and a "fifth mapping relationship." The fourth mapping relationship and the fifth mapping relationship can be a table of different activated beam combinations and their corresponding SSB transmit power adjustment values, or a function or equation for different activated beam combinations, or can be referred to as a "mapping rule," "mapping method," "corresponding relationship," "configuration table," and the like.

[0187] In this way, for different activation beam combinations, the terminal device or network device can determine the adjustment value of the current SSB transmit power, the adjustment value of the current CSI-RS transmit power offset, and the adjustment value of the current PDSCH transmit power offset, thereby adjusting the PDSCH transmit power.

[0188] [Scheme 4]

[0189] The terminal device or network device obtains indication information, which is used to indicate the adjustment value corresponding to the downlink signal / channel transmission power, and then adjusts the SSB transmission power according to the indication information. The indication information can be carried by DCI or MAC CE.

[0190] The following four situations are described below:

[0191] First case:

[0192] In the "first case", the indication information includes the SSB transmit power adjustment value corresponding to the SSB index. In this way, when the terminal device or the network device obtains the indication information, the terminal device or the network device increases the transmit power of the current SSB by the SSB transmit power adjustment value corresponding to the SSB index of the current SSB.

[0193] It should be noted that the transmission power adjustment values of SSBs corresponding to different SSB indexes may be the same or different.

[0194] Taking the indication information carried by MAC CE as an example, Figure 6 In the MAC CE, a MAC subheader is identified by a MAC subheader, whose LCID is a specific value. The MAC CE may include the following fields:

[0195] BWP ID field: This field can be used to indicate the BWP to which the MAC CE applies, and the length of this field is 2 bits;

[0196] Serving Cell ID field: This field can be used to indicate the identifier of the serving cell, and the length of this field is 2 bits;

[0197] R field: This field indicates reservation;

[0198] As shown in the figure, MAC-CE is used as indication information to indicate the adjustment value of each SSB in the cell. There are 8 SSBs in the cell. RRC first configures candidate values for SSB power adjustment, such as 4, represented as {x1, x2, x3, x4}. MAC-CE indicates the power adjustment value for each SSB separately, and each SSB occupies 2 bits.

[0199] certainly, Figure 6 This is only an example of the structure of the MAC CE, and this embodiment does not limit the structure of the MAC CE.

[0200] Taking the indication information carried by DCI as an example, Figure 7In the figure, the notification method for receiving the indication information by the terminal device or the network device can be DCI. As shown in the figure, DCI is used as indication information to indicate the adjustment value of each SSB in the cell. There are 8 SSBs in the cell. RRC first configures the candidate values of SSB power adjustment, such as 4, expressed as {x1, x2, x3, x4}. DCI uses 2 bits to indicate the power adjustment value for each SSB. This DCI can be a new DCI format or an existing DCI format, and can contain scheduling data or not.

[0201] certainly, Figure 7 This is only an example of the structure of DCI, and this embodiment does not limit the structure of DCI.

[0202] Second case:

[0203] In the second case, the indication information includes the SSB transmit power adjustment value corresponding to the SSB combination. Thus, when the terminal device or network device obtains the indication information, the terminal device or network device increases the transmit power of each SSB in the current SSB combination by the SSB transmit power adjustment value corresponding to the current SSB combination.

[0204] It should be noted that the SSB transmission power adjustment values corresponding to different SSB combinations may be the same or different.

[0205] Taking the indication information carried by MAC CE as an example, Figure 8 In the MAC CE, a MAC subheader is identified by a MAC subheader, whose LCID is a specific value. The MAC CE may include the following fields:

[0206] BWP ID field: This field can be used to indicate the BWP to which the MAC CE applies, and the length of this field is 2 bits;

[0207] Serving Cell ID field: This field can be used to indicate the identifier of the serving cell, and the length of this field is 2 bits;

[0208] R field: This field indicates reservation;

[0209] As shown in the figure, MAC-CE is used as an indication to indicate the adjustment value for each SSB in the cell. There are eight SSBs in the cell. RRC groups one or more SSBs into a group and indicates the power adjustment value for each SSB group. For example, SSB1 to SSB3, SSB4 to SSB6, and SSB7 to SSB8 are divided into three groups, or the non-contiguous SSB indices {1, 2, 5}, {3, 8}, and {4, 7} are divided into three groups. RRC first configures candidate SSB power adjustment values, such as four, represented as {x1, x2, x3, x4}. There are three SSB groups in the cell. MAC-CE indicates the power adjustment value for each SSB group, with each SSB group occupying 2 bits.

[0210] certainly, Figure 8 This is only an example of the structure of the MAC CE, and this embodiment does not limit the structure of the MAC CE.

[0211] Taking the indication information carried by DCI as an example, Figure 9 In the example, the terminal device or network device can receive the indication information through DCI. As shown in the figure, DCI is used as indication information to indicate the adjustment value for each SSB in the cell. There are 8 SSBs in the cell. RRC groups one or more SSBs into a group and indicates the power adjustment value for each SSB group. For example, SSB1 to SSB3, SSB4 to SSB6, and SSB7 to SSB8 are divided into three groups, or the non-contiguous SSB indices {1, 2, 5}, {3, 8}, and {4, 7} are divided into three groups. RRC first configures candidate SSB power adjustment values, such as 4, represented as {x1, x2, x3, x4}. There are 3 SSB groups in the cell. DCI uses 2 bits to indicate the power adjustment value for each SSB group. This DCI can be a new DCI format or an existing DCI format and can contain or not contain scheduling data.

[0212] certainly, Figure 9 This is only an example of the structure of DCI, and this embodiment does not limit the structure of DCI.

[0213] The third case:

[0214] In the third case, the indication information includes SSB transmit power adjustment values corresponding to SSB indexes in multiple time windows. Thus, when the terminal device or network device obtains the indication information, the terminal device or network device increases the transmit power of the current SSB in the current time window by the SSB transmit power adjustment value corresponding to the SSB index of the current SSB.

[0215] It should be noted that the durations of multiple time windows may be the same or different, multiple time windows may be repeated periodically, and the transmission power adjustment values of SSBs corresponding to different SSB indexes may be the same or different.

[0216] Taking the indication information carried by MAC CE as an example, Figure 10 In the MAC CE, a MAC subheader is identified by a MAC subheader, whose LCID is a specific value. The MAC CE may include the following fields:

[0217] BWP ID field: This field can be used to indicate the BWP to which the MAC CE applies, and the length of this field is 2 bits;

[0218] Serving Cell ID field: This field can be used to indicate the identifier of the serving cell, and the length of this field is 2 bits;

[0219] R field: This field indicates reservation;

[0220] As shown in the figure, MAC-CE is used as indication information to indicate the adjustment value of each SSB in the cell. There are 8 SSBs in the cell. RRC first configures candidate values for SSB power adjustment, such as 4, represented as {x1, x2, x3, x4}. MAC-CE indicates the power adjustment value for each SSB separately, and each SSB occupies 2 bits.

[0221] certainly, Figure 10 This is only an example of the structure of the MAC CE, and this embodiment does not limit the structure of the MAC CE.

[0222] Taking the indication information carried by DCI as an example, Figure 11 In the figure, the notification method for receiving the indication information by the terminal device or the network device can be DCI. As shown in the figure, DCI is used as indication information to indicate the adjustment value of each SSB in the cell. There are 8 SSBs in the cell. RRC first configures the candidate values of SSB power adjustment, such as 4, expressed as {x1, x2, x3, x4}. DCI uses 2 bits to indicate the power adjustment value for each SSB. This DCI can be a new DCI format or an existing DCI format, and can contain scheduling data or not.

[0223] certainly, Figure 11 This is only an example of the structure of DCI, and this embodiment does not limit the structure of DCI.

[0224] The fourth case:

[0225] In the fourth case, the indication information includes SSB transmit power adjustment values corresponding to SSB combinations within multiple time windows. Thus, when the terminal device or network device obtains the indication information, the terminal device or network device increases the transmit power of each SSB in the current SSB combination within the current time window by the SSB transmit power adjustment value corresponding to the current SSB combination.

[0226] It should be noted that the durations of multiple time windows may be the same or different, multiple time windows may be repeated periodically, and the transmission power adjustment values of SSBs corresponding to different SSB combinations may be the same or different.

[0227] Taking the indication information carried by MAC CE as an example, Figure 12 In the MAC CE, a MAC subheader is identified by a MAC subheader, whose LCID is a specific value. The MAC CE may include the following fields:

[0229] Serving Cell ID field: This field can be used to indicate the identifier of the serving cell, and the length of this field is 2 bits;

[0230] R field: This field indicates reservation;

[0231] As shown in the figure, MAC-CE is used as an indication to indicate the adjustment value for each SSB in the cell. There are eight SSBs in the cell. RRC groups one or more SSBs into a group and indicates the power adjustment value for each SSB group. For example, SSB1 to SSB3, SSB4 to SSB6, and SSB7 to SSB8 are divided into three groups, or the non-contiguous SSB indices {1, 2, 5}, {3, 8}, and {4, 7} are divided into three groups. RRC first configures candidate SSB power adjustment values, such as four, represented as {x1, x2, x3, x4}. There are three SSB groups in the cell. MAC-CE indicates the power adjustment value for each SSB group, with each SSB group occupying 2 bits.

[0233] Taking the indication information carried by DCI as an example, Figure 13In the example, the terminal device or network device can receive the indication information through DCI. As shown in the figure, DCI is used as indication information to indicate the adjustment value for each SSB in the cell. There are 8 SSBs in the cell. RRC groups one or more SSBs into a group and indicates the power adjustment value for each SSB group. For example, SSB1 to SSB3, SSB4 to SSB6, and SSB7 to SSB8 are divided into three groups, or the non-contiguous SSB indices {1, 2, 5}, {3, 8}, and {4, 7} are divided into three groups. RRC first configures candidate SSB power adjustment values, such as 4, represented as {x1, x2, x3, x4}. There are 3 SSB groups in the cell. DCI uses 2 bits to indicate the power adjustment value for each SSB group. This DCI can be a new DCI format or an existing DCI format and can contain or not contain scheduling data.

[0234] certainly, Figure 13 This is only an example of the structure of DCI, and this embodiment does not limit the structure of DCI.

[0235] [Scheme 5]

[0236] The terminal device or network device obtains indication information, which is used to indicate the adjustment value corresponding to the downlink signal / channel transmission power. Then, the terminal device or network device adjusts the transmission power of the CSI-RS according to the indication information, wherein the indication information can be carried by DCI or MAC CE.

[0237] The following eight situations are described below.

[0238] First case:

[0239] In the first case, the indication information includes the adjustment value of the CSI-RS transmit power offset corresponding to the CSI-RS index. Thus, when a terminal device or network device obtains the indication information, it increases the transmit power of the current CSI-RS by the adjustment value of the CSI-RS transmit power offset corresponding to the CSI-RS index of the current CSI-RS.

[0240] It should be noted that the adjustment values of the CSI-RS transmit power offsets corresponding to different CSI-RS indexes may be the same or different.

As shown in the figure, DCI is used as indication information to indicate the adjustment value of the power offset of each CSI-RS in the cell. There are 8 CSI-RSs in the cell. RRC first configures candidate values for the CSI-RS power offset adjustment, such as 4, expressed as {x1, x2, x3, x4}. DCI uses 2 bits to indicate the adjustment value of the power offset for each CSI-RS. This DCI can be a new DCI format or an existing DCI format, and can contain scheduling data or not.

[0248] certainly, Figure 7 This is only an example of the structure of DCI, and this embodiment does not limit the structure of DCI.

[0249] Second case:

[0250] In the second case, the indication information includes a first adjustment value combination corresponding to the CSI-RS index. The first adjustment value combination refers to the CSI-RS transmit power offset adjustment value and the SSB transmit power adjustment value. Thus, when a terminal device or network device obtains the indication information, it increases the transmit power of the current CSI-RS by the first adjustment value combination corresponding to the CSI-RS index of the current CSI-RS.

[0251] It should be noted that the first adjustment value combinations corresponding to different CSI-RS indexes may be the same or different.

This DCI can be a new DCI format or an existing DCI format, and can include scheduling data or not.

[0259] certainly, Figure 7 This is only an example of the structure of DCI, and this embodiment does not limit the structure of DCI.

[0260] The third case:

[0261] In the third case, the indication information includes the adjustment value of the CSI-RS transmit power offset corresponding to the CSI-RS combination. Thus, when the terminal device or network device obtains the indication information, it increases the transmit power of each CSI-RS in the current CSI-RS combination by the adjustment value of the CSI-RS transmit power offset corresponding to the current CSI-RS combination.

[0262] It should be noted that the adjustment values of the CSI-RS transmit power offsets corresponding to different CSI-RS combinations may be the same or different.

[0267] As shown in the figure, MAC-CE serves as indication information to indicate the transmit power offset adjustment value for each CSI-RS in a cell. A cell contains eight CSI-RSs. RRC groups one or more CSI-RSs into a group and indicates the power adjustment value for each CSI-RS group. For example, CSI-RS1 to CSI-RS3, CSI-RS4 to CSI-RS6, and CSI-RS7 to CSI-RS8 are grouped into three groups, or the discontinuous CSI-RS indices {1, 2, 5}, {3, 8}, and {4, 7} are grouped into three groups. RRC first configures candidate CSI-RS transmit power offset adjustment values, such as four, represented as {x1, x2, x3, x4}. There are three CSI-RS groups in a cell. MAC-CE indicates the CSI-RS transmit power offset adjustment value for each CSI-RS group, with each CSI-RS group occupying two bits.

As shown in the figure, the DCI serves as indication information to indicate the transmit power offset adjustment value for each CSI-RS in the cell. A cell contains eight CSI-RSs. RRC groups one or more CSI-RSs into a group and indicates the power adjustment value for each CSI-RS group. For example, CSI-RS1 to CSI-RS3, CSI-RS4 to CSI-RS6, and CSI-RS7 to CSI-RS8 are grouped into three groups, or the discontinuous CSI-RS indices {1, 2, 5}, {3, 8}, and {4, 7} are grouped into three groups.

Thus, when a terminal device or network device obtains the indication information, it increases the transmit power of each CSI-RS in the current CSI-RS combination by the second adjustment value combination corresponding to the CSI-RS index of the current CSI-RS.

[0273] It should be noted that the second adjustment value combinations corresponding to different CSI-RS combinations may be the same or different.

Thus, when the terminal device or network device obtains the indication information, the terminal device or network device increases the transmit power of the current PDSCH by the adjustment value of the PDSCH transmit power offset corresponding to the PDSCH index of the current PDSCH.

[0331] It should be noted that the adjustment values of the PDSCH transmit power offsets corresponding to different PDSCH indices may be the same or different.

Thus, when the terminal device or network device obtains the indication information, the terminal device or network device increases the transmit power of each PDSCH in the current PDSCH combination within the current time window by the eighth combination of adjustment values corresponding to the current PDSCH combination.

[0408] It should be noted that the durations of the multiple time windows may be the same or different, the multiple time windows may be repeated periodically, and the eighth adjustment value combinations corresponding to different PDSCH combinations may be the same or different.
