[0047] In one embodiment, the method further includes: receiving a third request message for the reference frequency domain unit sent by the second node, and notifying the second node of the reference frequency domain unit, wherein the third request message carries identification information of the reference frequency domain unit; or receiving a fourth request message for the reference frequency domain unit sent by the second node, wherein the fourth request message carries identification information of the reference frequency domain unit, that is, the second node does not need to be notified after receiving the fourth request message; or informing the second node of the reference frequency domain unit.

[0048] In another embodiment, the method further includes: receiving capability information sent by the second node, wherein the capability information indicates whether the second node needs time-frequency resources to perform power adjustment training on one or more frequency domain units before power adjustment on the one or more frequency domain units.

[0049] The power information in this embodiment is power information associated with at least one of the following: beam, time unit, modulation scheme, waveform, signal channel, MIMO order, and transmission mode.

[0050] The modulation scheme in this embodiment includes at least one of the following: Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), 16QAM, 64QAM, 256QAM, 1024QAM, and 4096QAM; the waveform includes at least one of the following: Orthogonal Time-Frequency-Space (OTFS), Discrete Fourier Transform Spread Spectrum Orthogonal Frequency Division Multiplexing (DFT-s-OFDM), Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM), and other OFDM-based waveforms; the time unit includes at least one of the following: one or more time slots, one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols, one or more subframes, one or more radio frames, a time period, or one or more time units in a frame structure definition; the transmission mode includes at least one of the following: diversity transmission, multiplexing transmission, single-user MIMO (SU-MIMO) transmission, multi-user MIMO (MU-MIMO) transmission, and multi-user MIMO (MU-MU) transmission.

[0052] The one or more frequency domain units in this embodiment are the frequency domain units in the request message sent by the second node; and / or the power information is grouped information, the grouped information includes one or more frequency domain unit groups, each frequency domain unit group includes one or more frequency domain units, the power of the frequency domain units in the group is the same, or the power difference between every two frequency domain units in the group is less than the first preset value; and / or the path loss information is grouped information, the grouped information includes one or more frequency domain unit groups, each frequency domain unit group includes one or more frequency domain units, the path loss of the frequency domain units in the group is the same, or the path loss difference between every two frequency domain units in the group is less than the second preset value.

[0053] In the related art, automatic gain control (AGC) is adjusted separately on one or several carriers. The problem with this approach is that it takes a certain amount of wireless resources and time to adjust the AGC for each of the one or several carriers. The power information in the embodiment of the present disclosure is used to instruct the second node to perform automatic gain control AGC configuration on one or more frequency domain units, which can solve the problem in the related art that it takes a certain amount of wireless resources and time to adjust the AGC for each of the one or several carriers. The AGC configuration of the frequency domain unit can be performed more quickly with an appropriate power setting, without consuming or reducing the consumption of time-frequency resources for determining the AGC setting, thereby saving energy consumption and spectrum resources, and improving spectrum efficiency and processing speed.

[0054] Figures 3-5 show the nodes and transmission directions in the network. As shown in Figures 3-5, the two nodes from top to bottom are called the first node and the second node, respectively. The first node and the second node are any of the following in the communication network: a user terminal (UE), an intermediate node that performs a relay function, a base station (BS), an access network (RAN), a mobility management entity (MME), a CU, a core network (CN), or a node for device-to-device (D2D) communication. The second node is any of the following in the communication network: a user terminal (UE), an intermediate node that performs a relay function, a base station (BS), an intermediate node that performs a relay function, or a node for device-to-device (D2D) communication.

The power information may include at least one of the following: transmitted power; transmit power spectrum density (PSD); effective isotropic radiated power (EIRP); and energy per resource element (EPRE).

[0056] Furthermore, the power information is power information associated with at least one of the following: beam; time unit; modulation scheme; waveform; signal, channel; MIMO order; SU / MU transmission mode.

[0057] A beam is at least one of the following: a beam associated with an SSB (SS / PBCH block), a beam associated with a pilot RS (Reference signal), and a beam associated with a channel. The pilot RS can be one of the following: a measurement pilot (e.g., CSI-RS, Channel-State Information-Reference Signal of LTE or NR system), a demodulation pilot (e.g., DMRS of LTE or NR system), a phase tracking pilot (e.g., PTRS, Phase Tracking Reference Signal of NR system), and a positioning pilot (e.g., PRS, Positioning Reference Signals of NR system). The measurement pilot is a pilot used for measuring the serving cell or adjacent cell or for measuring the sum of interference and noise of other cells other than the main interference, the demodulation pilot is a pilot used for demodulating data, the phase tracking pilot is a pilot used for phase estimation, and the positioning pilot is a pilot used to locate the position of the device. The way of dividing pilots varies in different communication systems. For example, the CRS of LTE can complete the above-mentioned demodulation and measurement functions. A channel can be one of the following: a control channel and a traffic channel.

[0058] A frequency domain unit can be at least one of the following: one or more frequency bands, one or more component carriers, one or more RBs, one or more subcarrier spacings, and frequency domain resources corresponding to a serving cell.

[0059] Furthermore, the first node determines a reference frequency domain unit for the second node in at least one of the following ways: the first node sends a message to the second node to inform a reference frequency domain unit; the first node and the second node agree on a reference frequency domain unit.

[0060] The first node informs the second node of power information of several frequency domain units, where the power information includes at least one of the following: transmitted power (Transmitted Power); transmitted power spectrum density (Power Spectrum Density, abbreviated as PSD); effective isotropic radiated power (EIRP); and energy per resource element (EPRE).

[0061] The frequency domain unit can be at least one of the following: a defined frequency band in the wireless spectrum, such as the operating bands in FR1 (Frequency Range 1, which ranges from 410MHz to 7125MHz) defined in 3gpp TS38101-1v18.3.0, the operating bands in FR2 (Frequency Range 2, which ranges from 24250MHz to 52600MHz) defined in TS38101-2 v18.3.0, and other frequency bands defined subsequently for these frequency ranges and frequency bands defined in other frequency ranges (for example, above 52600MHz); the frequency bands can also be defined by standard organizations such as IEEE, such as K band, S band, etc.

[0062] A component carrier with a certain bandwidth within the frequency band, for example, the commonly used bandwidths are 5MHz, 10MHz, 15MHz, 20MHz, 25MHz, 30MHz, 35MHz, 40MHz, 45MHz, 50MHz, 55MHz, 60MHz, 70MHz, 80MHz, 90MHz, 100MHz corresponding to FR1 and other bandwidths introduced subsequently; a BWP (Bandwidth Part) composed of a certain resource block (RB).

[0063] The first node receives power request information for several frequency domain units from the second node, and the first node informs the second node of the power information for the aforementioned several frequency domain units. Alternatively, the first node informs the second node of the power information for several frequency domain units. Alternatively, the first node receives power request information for several frequency domain units from the second node, and the first node informs the second node of the power information for several frequency domain units. Here, the several frequency domain units informed by the first node may be the several frequency domain units requested by the second node or the several frequency domain units different from the several frequency domain units requested by the second node.

[0064] Figure 6 is a schematic diagram of the frequency domain unit of this embodiment. As shown in Figure 6, band b_1,…,band b_N are frequency domain units divided with band as the granularity. The definition of band can refer to the band definition in 3gpp TS 36.104 or 3gpp TS 38.104. CC c_1,…,CC c_N are component carriers of one or more bands. RB range r_1,…,RB range r_N are several RB resource sets with RB as the granularity. SCS range s_1,…,SCS range s_N are several SCS resource sets with SCS as the granularity. frequency range f_1,…,frequency range f_N are several frequency domain sets indicating specific frequency domain ranges, for example, indicating a starting frequency and an ending frequency, and the units can be Hz, kHz, MHz, etc.

[0065] FIG7 is a first schematic diagram of power information notification according to this embodiment. As shown in FIG7 , the frequency domain unit may also be a frequency domain resource corresponding to a cell of the second unit.

[0066] The transmit power may be a linear value, such as watts (W), milliwatts (mW), etc., and the transmit power may be a decibel value, such as decibel watts (dBW), decibel milliwatts (dBm), etc. For example, the first node notifies the transmit power of the first frequency domain unit as P_FU1 = a dBm, and the first node notifies the transmit power of the second frequency domain unit as P_FU2 = b dBm.

[0067] Figure 8 is a second schematic diagram of power information notification according to this embodiment. As shown in Figure 8, the power information of one or more frequency domain units notified to the second node by the first node may be the transmit power of one frequency domain unit, and the power offset of other frequency domain units relative to a reference frequency domain unit. For example, the first node notifies the first frequency domain unit that the transmit power is P_FU1 = a dBm, and the first node notifies the second frequency domain unit of the transmit power offset OFFSET_FU1_FU2 = b dB relative to the reference frequency domain unit, indicating that the transmit power corresponding to the second frequency domain unit is a + b dBm. In this embodiment, the reference frequency domain unit is the first frequency domain unit.

[0068] FIG9 is a third schematic diagram of power information notification according to this embodiment. As shown in FIG9 , the first node and the second node agree on a default or reference frequency domain unit, and the first node informs the second node of the offset of one or more frequency domain units relative to the reference frequency domain unit. For example, the primary cell (PCell) of the second node, the primary secondary cell (PSCell) of the second node, or the cell that transmits a synchronization signal and a physical broadcast channel block (SSB) to the second node, or the cell with the smallest or largest index value in the cell group where the second node is located.

[0069] The above does not traverse all power units and offset units, and the power unit and offset unit combinations disclosed in this disclosure are not limited to the above examples. The above describes a first node notifying a second node of power information of two frequency domain units. The first node notifying a second node of power information of more than two frequency domain units is also within the scope of protection of this disclosure.

[0070] FIG10 is a fourth schematic diagram of power information notification according to this embodiment. As shown in FIG10 , the power information of one or more frequency domain units notified to the second node by the first node may be the power spectral density (PSD) of the frequency domain units. PSD is the power in a certain bandwidth unit, where the bandwidth unit may be Hz, kHz, MHz, the bandwidth corresponding to one or more subcarrier spacings (SCS), the bandwidth corresponding to one or more RBs, one RB including several subcarrier spacings, generally 12 subcarrier spacings, and other values ​​are not excluded. The subcarrier spacing is 15000 Hz*2^u, where u is an integer including 0, such as {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. Power units include watts (W), milliwatts (mW), decibel watts (dBW), and decibel milliwatts (dBm). Therefore, the units of power spectral density include W / Hz, W / kHz, W / MHz, mW / Hz, mW / kHz, mW / MHz, dBm / SCS, dBm / RB, and the like. The first node notifies that the transmit power spectral density of the first frequency domain unit is PSD_FU1, and the first node notifies that the transmit power spectral density of the second frequency domain unit is PSD_FU2.

[0071] FIG11 is a fifth schematic diagram of power information notification according to this embodiment. As shown in FIG11 , the first node notifies the transmit power spectrum density PSD_FU1 of the first frequency domain unit, and the first node notifies the transmit power spectrum density of the second frequency domain unit, and the offset of the transmit power spectrum density relative to the transmit power spectrum density of the reference frequency domain unit is OFFSET_FU1_FU2. The reference frequency domain unit in this example is the first frequency domain unit. In actual implementation, the reference frequency domain unit may be a frequency domain unit other than the first frequency domain unit. The unit of the offset of its transmit power spectrum density may be a decibel value or a linear value. For example, if the first node notifies the transmit power spectrum density of the first frequency domain unit as a dBm / RB, and the first node notifies the second frequency domain unit as delta relative to the reference frequency domain unit (the first frequency domain unit in this example), then the transmit power spectrum density corresponding to the second frequency domain unit is a+delta dBm / RB. For another example, the first node informs that the transmission power spectrum density of the first frequency domain unit is a mW / Hz, and the first node informs that the power spectrum density of the second frequency domain unit relative to the reference frequency domain unit (the first frequency domain unit in this example) is delta, then it means that the transmission power spectrum density of the first node in the second frequency domain unit is a+delta mW / Hz.

[0072] The above does not traverse all power spectrum density units and offset units, and other combinations of power spectrum density units and offset units are also within the protection scope of the present disclosure.

[0073] Furthermore, the power information is power information associated with one or more beams.

[0074] Figure 12 is a schematic diagram of the correspondence between frequency domain units and power information according to this embodiment. As shown in Figure 12, there are several corresponding beams for the first frequency domain unit, the beams of two frequency domain units and the corresponding power information. Specifically, the first node informs the second node of the power information corresponding to one or more beams of one or more frequency domain units. Alternatively, the first node informs the second node of the power information corresponding to one or more beams associated with a certain signal or channel of one or more frequency domain units. The beam associated with a signal in NR uses a transmission configuration indicator (TCI) or a sounding reference signal resource indicator (SRS Resource Indicator, SRI) (Sounding Reference Signal, SRS) to associate the beam to inform the second node of the power information corresponding to one or more beams of one or more frequency domain units. It should be noted that the relationship between the beams and power information of more frequency domain units is not given in Figure 12.

[0075] Furthermore, the power information is power information related to one or more modulation schemes.

[0076] The modulation schemes commonly used in current communication systems include BPSK, QPSK, 16QAM, 64QAM, 256QAM, and 1024QAM. In the future, higher modulation schemes such as 4096QAM may be supported.

[0077] Figure 13 is a sixth schematic diagram of power information notification according to this embodiment. As shown in Figure 13, the first node notifies the second node of power information corresponding to one or more modulation sets for multiple frequency domain units. When the first node classifies all modulation schemes into the same set, it means that the first node notifies the second node of power information corresponding to all modulation schemes for one frequency domain unit. When the first node classifies each modulation scheme into a separate set, it means that the first node notifies the second node of power information corresponding to one or more modulation schemes of multiple modulation schemes for one frequency domain unit.

[0078] The above does not traverse all sets of combinations of modulation schemes, and other sets of combinations of modulation schemes are also within the protection scope of this disclosure.

[0079] Furthermore, the power information is power information related to the waveform.

[0080] Commonly used waveforms in communication systems include Orthogonal Time and Frequency Space (OTFS), Discrete Fourier Transform-spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM), Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM), or other OFDM-based waveforms.

[0081] The first node informs the second node of the power information of one or more waveforms. Figure 14 is a schematic diagram of the power information notification according to the present embodiment. As shown in Figure 14, the first node divides the waveforms into sets, and the first node informs several frequency domain units of the power information corresponding to one or more waveform sets. When the first node classifies all waveforms into the same set, it means that the first node informs the second node of the power information corresponding to all waveforms of a frequency domain unit. When the first node classifies each waveform into a separate set, it means that the first node informs the second node of the power information corresponding to each of the several waveforms of a frequency domain unit.

[0082] Furthermore, the power information is power information related to a time pattern.

[0083] The first node informs the second node of information associated with the power information and a specific time unit. For example, the first node unit informs the power information of one or more time units. The time unit can be one or more time slots, one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols, one or more sub-frames, one or more radio frames, or a combination of the foregoing time units. The time unit can also be a number of seconds or milliseconds in units such as seconds (s) or milliseconds (ms). The time unit can also be one or more time units in the definition of a frame structure. For example, a frame structure period includes several uplink subframes (or time slots), several downlink subframes (or time slots), and several flexible subframes (or time slots, or OFDM symbols). The first node can inform the power information of several subframes or time slots or OFDM symbols or a combination thereof within the frame structure period.

[0084] FIG15 is a first schematic diagram of power information notification according to this embodiment. As shown in FIG15 , several time units are indicated within a frame structure period. The power information for several time units marked as D is a1, the power information for several time units marked as D is a2, the power information for several time units marked as F is a1, the power information for several time units marked as F is a2, and there is no power information for time units marked as U. FIG15 is merely an example and does not traverse all frame structure configuration combinations, nor does it traverse the power information for each frame structure combination. For example, the power information for some time units marked as D can be configured, or the power information for some or all time units marked as U can be configured.

[0085] Figure 16 is the second flowchart of power information notification according to this embodiment. As shown in Figure 16, the first node notifies the second node about the power information of several time units according to the time unit. The time corresponding to one or several time units is M ms. Optionally, M takes values ​​such as 1, 1 / 2, 1 / 4, 1 / 8, 1 / 16, etc. The total time in the figure is N ms. Optionally, N takes values ​​such as 20, 40, 80, 160, 320, 640, etc.

[0086] The time unit may also be the time corresponding to one or several time slots, the time corresponding to one or several subframes, the time corresponding to one or several OFDM symbols, or the time corresponding to one or more radio frames.

[0087] Furthermore, the power information is power information related to signals and channels. Signals and channels are divided into synchronization signals, broadcast channels, pilot signals, service channels, and control channels. Pilot signals are further divided into pilot signals for measurement, pilot signals for demodulation, pilot signals for measurement, and pilot signals for estimating phase noise. For example, the first node informs the second node of the power information of signal channel 1 of the first frequency domain unit, and the first node informs the second node of the power information of signal channel 2 of the second frequency domain unit. Signal channel 1 and signal channel 2 are at least one of the above-mentioned signals and channels respectively.

[0088] Furthermore, the power information is power information related to a transmission mode, which can be classified into diversity transmission, multiplexing transmission, SU-MIMO transmission, MU-MIMO transmission, large CDD transmission, small CDD transmission, and no CDD transmission.

[0089] The first node notifies the second node of power information related to one or more transmission modes of one or more frequency domain units. For example, the first node notifies the second node of power information of transmission mode 1 of the first frequency domain unit, and the first node notifies the second node of power information of transmission mode 2 of the second frequency domain unit. The transmission mode 1 and transmission mode 2 are respectively at least one of the above transmission modes.

[0090] Furthermore, the power information is power information that groups power according to power ranges. For example, power information of several frequency domain units belongs to the range of group 1 (group_1), power information of several frequency domain units belongs to the range of group 2 (group_2), and so on.

[0091] The first node divides power information into several levels based on step values. Assume that the transmit power of the first node is p_min dBm ˉ p_max dBm, where p_min is the minimum transmit power and p_max is the maximum transmit power. The first node divides the transmit power into N levels based on the step value p_step. N = ceil((p_max - p_min) / p_step), where ceil() represents rounding up. Preferably, p_step is an integer greater than 0. The groups are denoted as p_level_1, p_level_2, ..., p_level_N. The minimum transmit power, maximum transmit power, and step value can be achieved by the first and second nodes reaching a consensus in one of the following ways: the first and second nodes agree on the values ​​of these variables, the first node informs the second node of the values ​​of these variables, and the first and second nodes determine the values ​​of these variables through negotiation. The negotiation process includes at least one of: the second node initiates a request for at least one of the desired minimum power, maximum power, and step value to the first node, and the first node replies to the second node with the values ​​of the minimum power, maximum power, and step value.

[0092] The above description uses transmit power as an example to illustrate that the first node notifies the second node of power information of one or more frequency domain units in a grouped manner.

[0093] The first node may send power information of one or more frequency domain units to the second node, or the EIRP of the frequency domain units. EIRP is the equivalent radiated power that takes into account beam gain. For the first frequency domain unit, the first node may provide power information of one or more EIRPs.

[0094] Figure 17 is a third schematic diagram of power information notification according to this embodiment. As shown in Figure 17, the first node notifies the second node of the power information of one or more frequency domain units, and the power information of one frequency domain unit includes the EIRP of one or more beams. The beam index here is the beam identified by the first node and the second node through beam training, the beam index number explicitly specified by the first node and the second node, or the implicit indication of the beam index by the first node and the second node. An example of implicit indication is the EIRP of the beam associated with the transmission configuration indicator (TCI) or the sounding reference signal resource indication SRI by the first node.

[0095] The first node uses at least one of the following signaling to inform the second node of power information of one or more frequency domain units: Radio Resource Control signaling (Radio Resource Control, abbreviated as RRC); Media Access Control-Control Element (Media Access Control-Control Element, abbreviated as MAC CE); Downlink Control Information (Downlink Control Information, abbreviated as DCI).

[0096] This embodiment also provides a method for obtaining power information. FIG18 is a flow chart of the method for obtaining power information according to an embodiment of the present disclosure. As shown in FIG18 , the method is applied to the second node. The flow chart includes the following steps:

[0097] Step S1802: receiving power information of one or more frequency domain units notified by the first node; and / or

[0098] Step S1804: Receive path loss information of one or more frequency domain units notified by the first node.

[0099] Through the above steps S1802 to S1804, the problem in the related art that the receiver needs time-frequency resources to adjust the power setting can be solved. By notifying the second node of the power information and / or path loss information, the second node does not need to consume time-frequency resources for power setting when receiving data from one or several carriers.

[0100] In this embodiment, the above step S1802 may specifically include: sending a first request message to the first node, and receiving power information of one or more frequency domain units returned by the first node; or receiving power information of one or more frequency domain units sent by the first node.

[0101] In this embodiment, the above step S1804 may specifically send a second request message to the first node and receive the path loss information of one or more frequency domain units returned by the first node; or receive the path loss information of one or more frequency domain units sent by the first node.

[0102] In one embodiment, the power information is actual power information or a power offset relative to a reference frequency domain unit; and / or the path loss information is actual path loss information or a path loss offset relative to a reference frequency domain unit.

[0103] In one embodiment, the reference frequency domain unit is a frequency domain unit for sending and receiving data with the second node; or the reference frequency domain unit is a frequency domain unit of a primary cell of the second node; or the reference frequency domain unit is a frequency domain unit of a cell with the smallest or largest component carrier index among the multiple frequency domain units.

[0104] In one embodiment, the method further includes: sending a third request message for the reference frequency domain unit to the first node, and receiving the reference frequency domain unit notified by the first node, wherein the third request message carries identification information of the reference frequency domain unit; or sending a fourth request message for the reference frequency domain unit to the first node, wherein the fourth request message carries identification information of the reference frequency domain unit; or receiving the reference frequency domain unit notified by the first node.

[0105] In one embodiment, the method further includes: sending capability information to the first node, wherein the capability information indicates whether the second node needs time-frequency resources to perform power adjustment training on one or more frequency domain units before power adjustment on the one or more frequency domain units.

[0106] The power information in this embodiment is power information associated with at least one of the following: beam, time unit, modulation scheme, waveform, signal channel, MIMO order, and transmission mode.

[0107] The modulation scheme in this embodiment includes at least one of the following: BPSK, QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, 4096QAM; the waveform includes at least one of the following: orthogonal time-frequency-space OTFS, discrete Fourier transform spread spectrum orthogonal frequency division multiplexing DFT-s-OFDM, cyclic prefix orthogonal frequency division multiplexing CP-OFDM, and other OFDM-based waveforms; the time unit includes at least one of the following: one or more time slots, one or more orthogonal frequency division multiplexing OFDM symbols, one or more subframes, one or more radio frames, time periods, and one or more time units in the frame structure definition; the transmission mode includes at least one of the following: diversity transmission, multiplexing transmission, SU-MIMO transmission, MU-MIMO transmission, CDD transmission, and CDD-free transmission.

[0108] The power information in this embodiment includes at least one of the following: transmit power TP; transmit power spectral density PSD, effective isotropic radiated power EIRP, energy EPRE of each resource unit; and / or the frequency domain unit includes at least one of the following: one or more frequency bands, one or more component carriers, one or more resource blocks RB, one or more subcarrier spacings, and frequency domain resources corresponding to a service cell.

[0109] In the embodiment of the present disclosure, after receiving the power information, the second node can perform automatic gain control AGC configuration on one or more frequency domain units according to the power information, which can solve the problem in the related technology that one or several carriers need to spend a certain amount of wireless resources and time to adjust the AGC. The AGC configuration of the frequency domain unit can be performed more quickly with appropriate power information, and time-frequency resources are not required to determine the AGC settings, thereby saving energy consumption and spectrum resources, and improving spectrum efficiency and processing speed.

[0110] The second node informs the first node of its capability information, where the capability information includes at least one of the following: the second node receives power information of one or more frequency domain units; the second node configures AGC of one or more frequency domain units.

[0111] The second node requests the first node for power information of one or more frequency domain units.

[0112] Furthermore, the second node requests the first node for power information of one or more frequency domain units, including a reference frequency domain unit, wherein the reference frequency domain unit may also be a reference frequency domain unit agreed upon by the first node and the second node.

[0113] The second node reports a capability to the first node, where the capability indicates that the second node can set the AGC of one or more frequency domain units according to power information of different frequency domain units.

[0114] The second node reports capability information to the first node, and the second node can set the AGC of one or more frequency domain units based on the power information of one or more frequency domain units. When the second node learns the power information of one or more frequency domain units informed by the first node, the second node sets the AGC of one or more frequency domain units. For example, the second node can determine the AGC setting of the second frequency domain unit based on the AGC setting of the first frequency domain unit, the AGC setting of the default frequency domain unit, or the AGC setting of the reference frequency domain unit, and the offset value of the power information of the second frequency domain unit and the first frequency domain unit. For example, the power information of the first frequency domain unit is p_1dBm, and the power information of the second frequency domain unit relative to the first frequency domain unit is p_2dBm. The first node receives the AGC setting of the first frequency domain unit as AGC_FU1, then the second node sets the AGC of the second frequency domain unit according to AGC_FU1+(p_1-p_2). After the above operation, the second node can ensure that the ADC input levels of one or more frequency domain units are roughly the same level.

[0115] The second node sends a request message to the first node, where the request message includes power information of one or more frequency domain units. The one or more frequency domain units are frequency domain units used for communication between the second node and the first node, or frequency domain units used for communication between the second node and another node (referred to herein as a third node).

[0116] The second node receives the one or more power information and sets the AGC for the frequency domain unit. Compared to when the second node does not receive the power information of the one or more frequency domain units from the first node, when the second node receives the power information of the one or more frequency domain units from the first node, the second node can receive data of the multiple frequency domain units more quickly.

[0117] If the second node does not receive the power information of one or more frequency domain units, the second node needs to use time-frequency resources to adjust the AGC. When the second node receives the power information of one or more frequency domain units, the second node can set the AGC of one or more frequency domain units as soon as possible.

[0118] For example, a second node maintains a connection with a first frequency domain unit of a first node and receives power information from the second frequency domain unit. The second frequency domain unit is a frequency domain unit for communication between the first and second nodes. Since the first and second frequency domain units are used for communication between the first and second nodes, the second node determines the AGC setting of the second frequency domain unit based on the power information of the first and second frequency domain units. For example, the power information of the first frequency domain unit is 30 dBm, and the power information of the second frequency domain unit is 33 dBm. The power information of the second frequency domain unit differs by 3 dB from the power information of the first frequency domain unit. Let the value of the AGC setting of the second node for the first frequency domain unit be AGC_1. If AGC_1 is a decibel value, the AGC setting value of the second node for the second frequency domain unit is AGC_1+(30-33). If AGC_1 is a linear value, the AGC setting value of the second node for the second frequency domain unit is AGC_2=AGC_1+db2lin(30-33), where the db2lin() operator represents the conversion of a decibel value to a linear value. Similarly, if AGC_1 is a linear value, and the power information of the first frequency domain unit and the power information of the second frequency domain unit are decibel values, when calculating the AGC setting value of the second frequency domain unit, the power information must first be converted into a linear value and then the AGC of the second power unit is adjusted. This will not be repeated here.

[0119] Furthermore, the power information of the one or more frequency domain units received by the second node may also be frequency domain units of other nodes other than the first node that communicate with the second node.

[0120] Figure 19 is a schematic diagram of path loss measurement according to this embodiment. As shown in Figure 19, the second node measures the path loss between the second and third nodes, and the path loss between the second and first nodes. Assuming the path loss between the second and first nodes is PL_21 (decibel value), the path loss between the second and third nodes is PL_23 (decibel value), the power information of the frequency domain units of the second and first nodes is p_1dBm, and the AGC setting value of the first frequency domain unit received by the second node is AGC_1 (linear value). Based on the power information p_2dBm of the third node reported by the first node, the second node can infer that the AGC setting of the second frequency domain unit received by the second node from the third node is AGC_1+db2lin(p_1-p_2+PL_21-PL_23), where db2lin() represents the conversion of decibel values ​​into linear values. If AGC, p_1, p_2, PL_21, and PL_23 are all decibel values, the AGC of the second frequency domain unit received by the second node from the third node is set to AGC_1+(p_2-p_1+PL_21-PL_23). The conversion combinations between decibel values ​​and linear values ​​in other cases are not repeated here.

[0121] The second node notifies the first node of the capability through at least one of the following signaling: radio resource control signaling, media access control-control element (MAC CE), uplink control information (UCI), and non-access stratum (NAS) signaling.

[0122] The first node sends one or more grouping information to the second node, and the power information of the frequency domain units in the group is equal or similar.

[0123] Similar power information means that the difference in power information of frequency domain units within a group is less than a threshold value, and the threshold value may be agreed upon or negotiated through signaling.

[0124] The second node sends a request message to the first node, requesting the first node for grouping of frequency domain node power information.

[0125] The first node sends one or more grouping information to the second node, and the path loss information of the frequency domain units in the group is equal or similar.

[0126] The path loss information being similar means that the difference in path loss between the frequency domain unit in the group and the notified node is less than a threshold value, and the threshold value may be agreed upon or negotiated through signaling.

[0127] The second node sends a request message to the first node, requesting the first node for grouping of frequency domain node path loss information.

[0128] An example of signaling for reporting a capability is as follows:

[0129] UE-RAT-Capability-vabcd::=SEQUENCE{

[0130] rat_dc-Parameters-vabcd RAT_DC-Parameters-vabcd

[0131] rat_ca-Parameters-vabcd RAT_CA-Parameters-vabcd

[0132] }

[0133] RAT indicates radio access technology, such as UTRA (UMTS), EUTRA (LTE), NR and other access technologies.

[0134] -vabcd indicates that the protocol version corresponding to the access wireless access technology is abcd.

[0135] RAT_DC-Parameters-vabcd indicates an example of dual connectivity (DC) parameters of the RAT technology.

[0136] RAT_DC-Parameters-vabcd::=SEQUENCE{

[0137] AGC-without-traning ENUMERATED{supported}OPTIONAL,

[0138] }

[0139] The above-mentioned AGC-without-training indicates that AGC of one or more carriers can be set without dedicated AGC training resources when performing reception of multiple carriers.

[0140] RAT_CA-Parameters-vabcd is an example of carrier aggregation (CA) parameters indicating the RAT technology.

[0141] RAT_CA-Parameters-vabcd::=SEQUENCE{

[0142] AGC-without-traning ENUMERATED{supported}OPTIONAL,

[0143] }

[0144] RAT_CA-Parameters-vabcd indicates the carrier aggregation (CA) parameters of the RAT technology.

[0145] Furthermore, the above signaling can also be associated with a specific carrier combination, which will not be repeated here. The above signaling is a signaling form for carrier aggregation or dual connectivity. It is also possible to consider splitting or merging UE-RAT-Capability-vabcd, RAT_DC-Parameters-vabcd, and RAT_CA-Parameters-vabcd in different forms. For example:

[0146] UE-RAT-Capability::=SEQUENCE{

[0147] rat_cadc-Parameters RAT_DC-Parameters

[0148] }

[0149] RAT_CADC-Parameters::=SEQUENCE{

[0150] AGC-without-traning ENUMERATED{supported}OPTIONAL,

[0151] }

[0152] For example,

[0153] UE-RAT-Capability-AGC-without-traning::=SEQUENCE{

[0154] agc-without-traningENUMERATED{supported}OPTIONAL,

[0155] }

[0156] An example of signaling for requesting power information of one or more frequency domain units is as follows:

[0157] CCPowerEnquiry-IEs::=SEQUENCE{

[0158] cc-Power-RequestList CCPower-RequestList

[0159] }

[0160] The CCPowerEnquiry-IEs mentioned above carry the power request information of one or more frequency domain units.

[0161] The CCPower-RequestList is a request list that lists power information of one or more frequency domain units to be acquired.

[0162] An example of signaling for a power grouping information request is as follows:

[0163] CCPowerGroupEnquiry-IEs::=SEQUENCE{

[0164] cc-PowerGroup-RequestList CCPowerGroup-RequestList

[0165] }

[0166] The CCPowerGroupEnquiry-IEs carries request information about the power grouping of one or more frequency domain units, wherein the CCPowerGroup-RequestList is a request list that lists the power grouping information of one or more frequency domain units to be obtained.

[0167] Alternatively, the second node only submits a power grouping request message, which does not carry a specific frequency domain unit list, and requests the first node to inform the power grouping information of the frequency domain units.

[0168] CCPowerGroupEnquiry-IEs::=SEQUENCE{

[0169] cc-PowerGroup-Request ENUMERATED{true}OPTIONAL,

[0170] }

[0171] An example of signaling for a path loss packet information request is as follows:

[0172] CCPathlossGroupEnquiry-IEs::=SEQUENCE{

[0173] cc-PathlossGroup-RequestList CCPowerGroup-RequestList

[0174] }

[0175] The CCPathlossGroupEnquiry-IEs carries the request information about the path loss grouping of one or more frequency domain units, wherein the CCPathlossGroup-RequestList is a request list that lists the path loss grouping information of one or more frequency domain units to be obtained.

[0176] Alternatively, the second node only submits a path loss grouping request message, which does not carry a specific frequency domain unit list, and requests the first node to inform the path loss grouping information of the frequency domain units.

[0177] CCPathlossGroupEnquiry-IEs::=SEQUENCE{

[0178] cc-PathlossGroup-Request ENUMERATED{true}OPTIONAL,

[0179] }

[0180] An example of signaling request information for a reference frequency domain unit is as follows:

[0181] PowerReferenceCCRequest::=SEQUENCE{

[0182] cc-SetIndexINTEGER(0..M)

[0183] cc-IndexInOneCC-SetINTEGER(0..N)

[0184] }

[0185] Through the above signaling, a node can request a reference frequency domain unit, specifically, including a CCset (component carrier set) index and a cc-IndexInOneCC-Set (component carrier index within a component carrier set index), where M and N are integers greater than 0.

[0186] A notification signaling of power information of one or more frequency domain units is as follows:

[0187] CCPowerInfo-IEs::=SEQUENCE{

[0188] cc-Power-InfoList CCPower-InfoList

[0189] }

[0190] The CCPowerInfo-IEs contains a list that includes power information of one or more frequency domain units. The following is an implementation of this list.

[0191] CCPowerInfoList::=SEQUENCE{

[0192] cc-SetIndexINTEGER(0..M)

[0193] cc-IndexInOneCC-SetINTEGER(0..N)

[0194] powerInfo PowerInfo

[0195] powerReferenceCC PowerReferenceCC

[0196] }

[0197] PowerReferenceCCR::=SEQUENCE{

[0198] cc-SetIndexINTEGER(0..M)

[0199] cc-IndexInOneCC-SetINTEGER(0..N)

[0200] }

[0201] The above cc-SetIndex is an index of a frequency domain unit set, and its value is an integer of 0ˉM, where M is greater than 0.

[0202] The above cc-IndexInOneCC-Set is a frequency domain unit index in a frequency domain unit set, and its value is an integer of 0ˉN, where N is greater than 0.

[0203] The powerInfo is specific power information, which may be the aforementioned power value, power spectrum density, EPRE, EIRP and other power quantities, or an offset relative to a reference frequency domain unit.

[0204] A notification signaling of frequency domain unit power grouping information is as follows:

[0205] CCPowerGroupInfo-IEs::=SEQUENCE{

[0206] cc-PowerGroup-List CCPowerGroup-List

[0207] }

[0208] The CCPowerGroupInfo-IEs contains a list including one or more frequency domain unit power grouping information. The following is a signaling example of this list.

[0209] CCPowerGroupList::=SEQUENCE(SIZE(1..maxNrofPowerGroup))OFPowerGroupList

[0210] PowerGroupList::=SEQUENCE{

[0211] groupIndex INTEGER(0..M)

[0212] cc-SetIndexSEQUENCE(SIZE(1..maxNrofCCperGroup))INTEGER(0..N)OPTIONAL

[0213] cc-IndexInOneCC-Set SEQUENCE(SIZE(1..maxNrofCCperGroup))INTEGER(0..J)OPTIONAL

[0214] delta_power INTEGER(0..J)OPTIONAL

[0215] }

[0216] CCPowerGroupList contains a list of one or more power groups, and the grouping information in the list is specifically indicated by PowerGroupList, which includes a group index. Optionally, PowerGroupList may also include a component carrier set index to indicate the component carrier set included in a power group. Optionally, PowerGroupList may also include a component carrier index within a component carrier set to indicate the component carrier index included in a power group or the component carrier index within a component carrier set. Optionally, PowerGroupList may also include a power deviation delta_power, which is used to indicate that the difference in power information of frequency domain units within a group is less than or equal to delta_power.

[0217] A capability report, for example, capability reporting through MAC CE signaling.

[0218] MAC CE reports that a node has the ability to set one or more carriers without AGC training as shown in Table 1.

[0219] Table 1

[0220] A request message, for example, requesting path loss information of one or more frequency domain units through MAC CE signaling, as shown in Table 2.

[0221] Table 2

[0222] The MAC CE requests the power information of one or more frequency domain units, as shown in Table 3.

[0223] Table 3

[0224] A row in Table 3 is divided into two fields, the first field indicates a CCset (component carrier set) index, and the second field indicates a CC (component carrier) index within a CCset.

[0225] Another request method is to carry only CCset, as shown in Table 4.

[0226] Table 4

[0227] Alternatively, the request only carries the CC_index. For example, there is only one CCset between the first node and the second node. In this case, the CC_index is the CC_index of this CCset.

[0228] The above signaling form requests power information of several CCsets. A CCset includes one or more CCs and is a specific embodiment of the frequency domain unit described in the article.

[0229] Another request method is to carry a reference frequency domain unit, as shown in Table 5.

[0230] Table 5

[0231] The power request information carrying the reference frequency domain unit may only carry the CCset index or CC_index.

[0232] MAC CE is the signaling used by one node to inform another node of the reference frequency domain unit, as shown in Table 6.

[0233] Table 6

[0234] Alternatively, one node only notifies another node of the set index where the reference frequency domain unit is located as shown in Table 7.

[0235] Table 7

[0236] The reference frequency domain unit notified in Table 7 carries only one component carrier set. Two nodes can agree that the CC with the smallest CCindex within the CCset is the reference frequency domain unit, or agree that the primary serving cell within the CCset is the reference frequency domain unit. MAC CE is signaling from one node to another to inform the power information of one or more frequency domain units, as shown in Table 8.

[0237] Table 8

[0238] In Table 9, Power_info1 and Power_infoK represent power values, power spectral density, EPRE, or EIRP. Furthermore, the power information may be power information associated with a beam, time unit, modulation scheme, waveform, or transmission mode. The power information may also be an index value of a power level. For example, the power value may be divided into several levels according to a step value, with each power level corresponding to an index.

[0239] As shown in Table 9, the power ranges corresponding to different indexes are given.

[0240] Table 9

[0241] The signaling for notifying the power information of one or more frequency domain units of a beam is shown in Table 10, where each row corresponds to a frequency domain unit and the power information of a beam.

[0242] Table 10

[0243] The MAC CE requests the power grouping of one or more frequency domain units as shown in Table 11.

[0244] Table 11

[0245] A row in Table 11 is divided into two fields, the first field indicates a CCset (component carrier set) index, and the second field indicates a CC (component carrier) index within a CCset.

[0246] Another request method is to carry only the CCset, querying the power group information for one or more frequency units, as shown in Table 12. Alternatively, the request signaling only carries the CC_index. For example, if there is only one CCset between the first and second nodes, the CC_index is the CC_index of this CCset. If no CCset is defined between the first and second nodes, the CC_index is the CC_index regardless of the CCset.

[0247] Table 12

[0248] The above signaling form requests power information of several CCsets. A CCset includes one or more CCs and is a specific embodiment of the frequency domain unit described in the article.

[0249] MAC CE is the signaling that one node uses to inform another node of one or more frequency domain unit power groups as shown in Table 13. The power groups in Table 13 can also be power groups associated with beams, time units, modulation schemes, waveforms, and transmission modes.

[0250] Table 13

[0251] One or more frequency domain unit power groups may also indicate power groups of component carrier sets. This notification method notifies the power groups of frequency domain units according to component carrier sets, as shown in Table 14.

[0252] Table 14

[0253] In Table 14, the correspondence between CCset_index and Group is an example. In actual situations, different CCset_index may correspond to the same Group.

[0254] Tables 1-14 above only provide fields related to the present disclosure, and may also include placeholder bits in actual implementation.

[0255] LCID values ​​are introduced for the MAC CEs such as capability reporting, power information request, and path loss information request, and are used for the MAC CE transmission mentioned in Table 1-14.

[0256] Table 15 MAC CE LCID value for capability reporting, power request, power information notification, reference frequency domain unit request, and reference frequency domain unit notification.

[0257] Table 15

[0258] The second node sends a capability reporting message to the first node through UCI and reports the capability through the PUCCH of 5G NR.

[0259] The second node uses a cyclic shift (CS) of the PUCCH to inform the first node of its capability of supporting AGC settings of one or more frequency domain units.

[0260] The second node requests the first node for power information of one or more frequency domain units through the UCI.

[0261] The second node transmits power information of one or more frequency domain units to the first node via a cyclic shift of the PUCCH. Specifically, the cyclic shift of the PUCCH may indicate the frequency domain unit. An example is as follows: the signaling for requesting power information of one or more frequency domain units using different cyclic shifts is shown in Table 16.

[0262] Table 16

[0263] Furthermore, the second node may use two or more sequences to report power information of one or more frequency domain units to the first node, for example, using different cyclic shifts of the first sequence to indicate CC_set and using cyclic shifts of the second sequence to indicate CC_index.

[0264] The second node requests power information of one or more frequency domain units using several bits of the UCI.

[0265] For example, the UCI bits are divided into two types of fields, one type of field indicates a carrier set CCset index, and the other type of field indicates a CC index within the carrier set CCset.

[0266] Two fields are used to indicate the CCset index and the CC index within the CCset, as shown in Table 17.

[0267] Table 17

[0268] Where ai(i∈[0,1,…,N-1]), bj(j∈[0,1,…,M-1]) takes the value of 0 or 1, which represents 2^N set index values, 2^N component carriers or cell (frequency domain unit) index values ​​within the set.

[0269] The second node sends the desired reference frequency domain unit to the first node through the UCI.

[0270] The second node uses the cyclic shift of UCI or several bits of UCI to send at least one of CC_set and CC_index to the first node. When there is a CC_set between the second node and the first node (network side) or the first node and the second node use cc_index to index different component carriers or cells (frequency domain units), the second node sends a cc_index to the first node to indicate a desired reference frequency domain unit. When there are two or more CC_sets between the second node and the first node, the second node sends a cc_set to the first node to indicate the cc_set (frequency domain unit set) where a desired reference frequency domain unit is located. The first node and the second node determine the component carrier (frequency domain unit) with the smallest CC_index in the CC_set as the reference frequency domain unit through an agreed method.

[0271] The first node notifies power information of one or more frequency domain units through DCI.
