[0061] A frequency domain unit can be at least one of the following ways: one or more frequency bands, one or more component carriers, one or more RBs, one or more subcarrier spacings, the frequency domain resources corresponding to a serving cell.
[0062] 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 notify a reference frequency domain unit; the first node and the second node agree on a reference frequency domain unit.
[0063] The first node notifies the second node of the power information of a plurality of frequency-domain units, and the power information includes at least one of the following: Transmitted Power; Power Spectrum Density (PSD for short); Effective Isotropic Radiated Power (EIRP for short); Energy Per Resource Element (EPRE for short).
[0064] The frequency-domain units can be at least one of the following: the defined frequency bands in the wireless spectrum, such as the operating bands in FR1 (Frequency Range 1, with a range of 410 MHz to 7125 MHz) defined in 3gpp TS38101-1 v18.3.0, the operating bands in FR2 (Frequency Range 2, with a range of 24250 MHz to 52600 MHz) defined in TS38101-2 v18.3.0, and other frequency bands and other frequency ranges (such as above 52600 MHz) defined for these frequency ranges in the future; the frequency bands can also be defined by standard organizations such as IEEE, such as K band, S band, etc.

[0066] The first node receives the power request information of a plurality of frequency-domain units from the second node, and the first node notifies the second node of the power information of the aforementioned plurality of frequency-domain units. Alternatively, the first node notifies the power information of a plurality of frequency-domain units. Or the first node receives the power request information of a plurality of frequency-domain units from the second node, and the first node notifies the second node of the power information of a plurality of frequency-domain units. Here, the plurality of frequency-domain units notified by the first node can be the plurality of frequency-domain units requested by the second node or different from the plurality of frequency-domain units requested by the second node.
[0067] Figure 6 is a schematic diagram of the frequency-domain units in this embodiment, as Figure 6As shown, bands b_1, …, b_N are frequency domain units divided by band granularity. The definition of band can refer to the band definition in 3GPP TS 36.104 or 3GPP TS 38.104. CCS c_1, …, c_N are component carriers of one or more bands. RB ranges r_1, …, r_N are several sets of RB resources with RB granularity. SCS ranges s_1, …, s_N are several sets of SCS resources with SCS granularity. Frequency ranges f_1, …, f_N are several frequency domain sets indicating specific frequency domain ranges, such as indicating a start frequency and an end frequency, and the unit can be Hz, kHz, MHz, etc.
[0068] Figure 7 is a schematic diagram of power information notification according to this embodiment Figure 1 , such as Figure 7 As shown, the frequency domain unit can also be the frequency domain resources corresponding to a cell of the second unit.
[0069] The transmit power can be a linear value, such as watt (W), milliwatt (mW), etc., or the transmit power can be a decibel value, such as decibel watt (dBW), decibel milliwatt (dBm), etc. For example, the first node notifies that the transmit power of the first frequency domain unit is P_FU1 = a dBm, and the first node notifies that the transmit power of the second frequency domain unit is P_FU2 = b dBm.
[0070] Figure 8 is a schematic diagram of power information notification according to this embodiment Figure 2 , such as Figure 8 As shown, the first node notifying the second node of the power information of one or more frequency domain units can be notifying the transmit power of one frequency domain unit and notifying the power offset of other frequency domain units relative to the reference frequency domain unit. For example, the first node notifies that the transmit power of the first frequency domain unit is P_FU1 = a dBm, and the first node notifies that the transmit power offset of the second frequency domain unit relative to the reference frequency domain unit is OFFSET_FU1_FU2 = b dB, which means 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.
[0071] Figure 9 is a schematic diagram of power information notification according to this embodiment Figure 3 , such as Figure 9As shown, the first node and the second node agree on a default or reference frequency domain unit, and the first node notifies 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 the synchronization signal and the 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.
[0072] The above does not traverse all the power units and offset units, and the combination of power units and offset units in this application is not limited to the above examples. The above describes that the first node notifies the second node of the power information of two frequency domain units, and the first node notifying the second node of the power information of more than two frequency domain units is also within the protection scope of this application.
[0073] Figure 10 is a schematic diagram of power information notification according to this embodiment Figure 4 , such as Figure 10 As shown, the power information of one or more frequency domain units notified by the first node to the second node may be the power spectral density (PSD) of the frequency domain unit. PSD is the power per unit of a certain bandwidth, where the bandwidth unit can be Hz, kHz, MHz, the bandwidth corresponding to one or several subcarrier spacings (SCS), the bandwidth corresponding to one or several resource blocks (RB). One RB includes several subcarrier spacings, usually taking 12 subcarrier spacings, and other values are not excluded. The subcarrier spacing is 15000Hz*2^u, where u is an integer including 0, such as {0,1,2,3,4,5,6,7,8,9,10}. The power units include watt (W), milliwatt (mW), decibel watt (dBW), and decibel milliwatt (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, etc. The first node notifies the transmitted power spectral density of the first frequency domain unit as PSD_FU1, and the first node notifies the transmitted power spectral density of the second frequency domain unit as PSD_FU2.
[0074] Figure 11 is a schematic diagram of power information notification according to this embodiment Figure 5 , such as Figure 11As shown, the first node notifies the transmit power spectral density PSD_FU1 of the first frequency domain unit. The first node notifies that the offset of the transmit power spectral density of the second frequency domain unit relative to the transmit power spectral density of the reference frequency domain unit is OFFSET_FU1_FU2. In this example, the reference frequency domain unit is the first frequency domain unit. In actual implementation, the reference frequency domain unit can be other frequency domain units other than the first frequency domain unit. The unit of the offset of its transmit power spectral density can be in decibel value or linear value. For example, the first node notifies that the transmit power spectral density of the first frequency domain unit is a dBm / RB, and the first node notifies that the power spectral 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 the corresponding transmit power spectral density of the second frequency domain unit is a + delta dBm / RB. Another example, the first node notifies that the transmit power spectral density of the first frequency domain unit is a mW / Hz, and the first node notifies that the power spectral 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 transmit power spectral density of the first node in the second frequency domain unit is a + delta mW / Hz.
[0075] The above does not traverse all the units of power spectral density and offset. Combinations of other units of power spectral density and offset are also within the protection scope of this application.
[0076] Furthermore, the power information is power information associated with one or more beams.
[0077] Figure 12 is a schematic diagram of the correspondence between the frequency domain unit and the power information according to this embodiment. As Figure 12 shown, 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 notifies the second node of the power information corresponding to one or more beams of one or more frequency domain units. Or, the first node notifies the second node of the power information corresponding to one or more beams of one or more frequency domain units associated with a certain signal or channel. In NR, the beams associated with a signal are associated with the beam in the form of Transmission Configuration Indicator (abbreviated as TCI) or Sounding Reference Signal Resource Indicator (abbreviated as SRI) (Sounding Reference Signal, abbreviated as SRS) to notify 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 Figure 12 does not give more relationships between the beams and power information of the frequency domain units.
[0078] Furthermore, the power information is power information related to one or more modulation schemes.
[0079] Common modulation schemes in current communication systems include BPSK, QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, and higher modulation schemes such as 4096QAM may be supported in the future.
[0080] Figure 13 Schematic of power information notification according to this embodiment Figure 6 , such as Figure 13 As shown, the first node notifies a plurality of frequency domain units of the power information corresponding to one or more modulation sets. When the first node classifies all modulation schemes into the same set, it means that the first node notifies the second node of the power information corresponding to all modulation schemes of a 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 the power information corresponding to one or more of several modulation schemes of a frequency domain unit.
[0081] The above does not traverse all combinations of modulation scheme sets, and other combinations of modulation scheme sets are also within the protection scope of this application.
[0082] Furthermore, the power information is power information related to waveforms.
[0083] Common waveforms in communication systems include Orthogonal Time and Frequency Space (abbreviated as OTFS), Discrete Fourier Transform-spread-Orthogonal Frequency Division Multiplexing (abbreviated as DFT-s-OFDM), Cyclic Prefix Orthogonal Frequency Division Multiplexing (abbreviated as CP-OFDM), or other OFDM-based waveforms.
[0084] The first node notifies the second node of the power information of one or more waveforms. Figure 14 Schematic of power information notification according to this embodiment Figure 7 , such as Figure 14As shown, the first node divides the waveform into sets, and the first node informs a plurality of 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 one frequency domain unit. When the first node divides each waveform into a separate set, it means that the first node informs the second node of the power information corresponding to each of a plurality of waveforms of one frequency domain unit.
[0085] Furthermore, the power information is power information related to a time pattern.
[0086] The first node informs the second node of the information that the power information is associated with specific time units. For example, the first node unit informs the power information of one or more time units. The time unit can be one or several time slots, one or several Orthogonal Frequency Division Multiplexing (OFDM) symbols, one or several sub-frames, one or several radio frames, or a combination of the foregoing time units. The time unit can also be several seconds or several milliseconds in units of seconds (s), milliseconds (ms), etc. The time unit can also be one or more time units defined in a frame structure, for example, within one frame structure period, there are several uplink sub-frames (or time slots), several downlink sub-frames (or time slots), several flexible sub-frames (or time slots, or OFDM symbols), and the first node can inform the power information of several sub-frames or time slots or OFDM symbols or their combination within the frame structure period.
[0087] Figure 15 It is a schematic diagram of the power information indication according to this embodiment Figure 1 , such as Figure 15 As shown, within one frame structure period, several time units are indicated. The power information of several time units marked as D is a1, the power information of several time units marked as D is a2, the power information of several time units marked as F is a1, the power information of several time units marked as F is a2, and the time units marked as U have no power information. Figure 15 This is only an example, without traversing all combinations of frame structure configurations, nor traversing the power information of each frame structure combination. For example, the power information of some time units marked as D can also be configured, or the power information of some or all time units marked as U can be configured.
[0088] Figure 16 It is the process of the power information indication according to this embodiment Figure 2 , such asFigure 16 As shown, the first node notifies the second node about the power information for several time units according to time units. 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. In the legend, the total time is N ms. Optionally, N takes values such as 20, 40, 80, 160, 320, 640, etc.
[0089] The time unit can 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.
[0090] Furthermore, the power information is power information related to signals and channels. Signals and channels are divided into synchronization signals, broadcast channels, pilot signals, traffic 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 notifies the second node about the power information of signal channel 1 in the first frequency domain unit, and the first node notifies the second node about the power information of signal channel 2 in the second frequency domain unit. Signal channel 1 and signal channel 2 are each at least one of the above signals and channels.
[0091] Furthermore, the power information is power information related to transmission modes. Transmission modes can be divided into diversity transmission, multiplexing transmission, SU-MIMO transmission, MU-MIMO transmission, large CDD transmission, small CDD transmission, and non-CDD transmission.
[0092] The first node notifies the second node about the power information related to one or more transmission modes in one or more frequency domain units. For example, the first node notifies the second node about the power information of transmission mode 1 in the first frequency domain unit, and the first node notifies the second node about the power information of transmission mode 2 in the second frequency domain unit. Transmission mode 1 and transmission mode 2 are each at least one of the above transmission modes.
[0093] Furthermore, the power information is power information that groups powers according to power ranges. For example, the power information of several frequency domain units belongs to the range of group 1 (group_1), the power information of several frequency domain units belongs to the range of group 2 (group_2), and so on.
[0094] The first node divides the power information into several levels according to the step value. Let the transmission power of the first node be p_min dBm to p_max dBm, where p_min is the minimum transmission power and p_max is the maximum transmission power. The first node divides the transmission power into N levels according to 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. Here, the groups are denoted as p_level_1, p_level_2,..., p_level_N respectively. The minimum transmission power, the maximum transmission power, and the step value can be implemented in one of the following ways to achieve the same understanding between the first node and the second node: The first node and the second node agree on the values of the above variables, the first node tells the second node the values of the above variables, or the first node and the second node determine the values of the above variables through a negotiation process. The negotiation process includes at least one of the following: The second node sends 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.
[0095] The above takes the transmission power as an example to illustrate that the first node tells the second node the power information of one or more frequency domain units in the form of grouping.
[0096] The power information of one or more frequency domain units sent by the first node to the second node can also be the EIRP of the frequency domain unit. EIRP is the equivalent radiated power considering the beam gain. For the first frequency domain unit, the first node can tell the power information of one or more EIRPs.
[0097] Figure 17 It is a schematic diagram of the power information indication according to this embodiment Figure 3 , such as Figure 17 shown, the first node tells the second node the power information of one or more frequency domain units. 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, which is the explicitly defined beam index number of 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 the implicit indication is the EIRP of the beam associated with the first node through the Transmission Configuration Indicator (TCI) or the SRI of the sounding reference signal resource.
[0098] The first node uses at least one of the following signaling to inform the second node of the power information of one or more frequency domain units: Radio Resource Control (RRC); Media Access Control - Control Element (MAC CE); Downlink Control Information (DCI).
[0099] In this embodiment, a method for obtaining power information is also provided, Figure 18 which is a flowchart of the method for obtaining power information according to the embodiment of the present application, as Figure 18 shown, applied to the second node. The process includes the following steps:
[0100] Step S1802, receiving the power information of one or more frequency domain units notified by the first node; and / or
[0101] Step S1804, receiving the path loss information of one or more frequency domain units notified by the first node.
[0102] Through the above steps S1802 to S1804, the problem that the receiver in the related art needs additional time-frequency resources to adjust the power setting can be solved. By directly notifying the second node of the power information and / or path loss information, it is ensured that the data of one or several carriers can be correctly received without consuming additional time-frequency resources for power setting.
[0103] In this embodiment, the above step S1802 may specifically include: sending a first request message to the first node and receiving the power information of one or more frequency domain units returned by the first node; or receiving the power information of one or more frequency domain units sent by the first node.
[0104] 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.
[0105] 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.
[0106] In one embodiment, the reference frequency domain unit is a frequency domain unit for transmitting and receiving data with the second node; or the reference frequency domain unit is a frequency domain unit of the primary cell of the second node; or the reference frequency domain unit is a frequency domain unit of the cell with the smallest or largest component carrier index among the multiple frequency domain units.
[0107] In one embodiment, the method further includes: sending a third request message for a reference frequency domain unit to the first node, and receiving the reference frequency domain unit notified by the first node, where identification information of the reference frequency domain unit is carried in the third request message; or sending a fourth request message for a reference frequency domain unit to the first node, where identification information of the reference frequency domain unit is carried in the fourth request message; or receiving the reference frequency domain unit informed by the first node.
[0108] In one embodiment, the method further includes: sending capability information to the first node, where 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 performing power adjustment on one or more frequency domain units.
[0109] 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, transmission mode.
[0110] 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 at least: 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, other OFDM-based waveforms; the time unit includes at least one of the following: one or several time slots, one or several orthogonal frequency division multiplexing OFDM symbols, one or several subframes, one or several radio frames, time period, 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, non-CDD transmission.
[0111] 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 per resource element EPRE; 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, frequency domain resources corresponding to one serving cell.
[0112] In an embodiment of the present application, after receiving 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 art that one or several carriers need to spend certain resources and time for AGC adjustment, and can perform AGC configuration on the frequency domain units with more appropriate power information faster, without the need for dedicated time-frequency resources to determine the AGC setting, saving energy consumption and spectrum resources and improving spectrum efficiency.
[0113] The second node informs the first node of the second node's capability information, and 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 for one or more frequency domain units.
[0114] The second node requests the first node for power information of one or more frequency domain units.
[0115] Further, the second node's request to the first node for power information of one or more frequency domain units includes a reference frequency domain unit. The reference frequency domain unit can also be a reference frequency domain unit agreed upon by the first node and the second node.
[0116] The second node reports a capability to the first node, and the capability indicates that the second node can set AGC for one or more frequency domain units according to the power information of different frequency domain units.
[0117] The second node reports capability information to the first node. The second node can set AGC for one or more frequency domain units according to 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 for one or more frequency domain units. For example, the second node can determine the AGC setting of the second frequency domain unit according to the AGC setting of the first frequency domain unit or the default frequency domain unit or the reference frequency domain unit and the offset value of the power information between the second frequency domain unit and the first frequency domain unit. For example, the power information of the first frequency domain unit is p_1 dBm, the power information of the second frequency domain unit relative to the first frequency domain unit is p_2 dBm, and the AGC setting of the first frequency domain unit received by the first node is 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 operations, the second node can ensure that the ADC input levels of one or more frequency domain units are roughly at the same level.
[0118] The second node sends a request message to the first node, and 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 other nodes (referred to as the third node here).
[0119] The second node receives one or more power information and sets the AGC of the frequency domain unit. Compared with the situation where the second node does not receive the power information of one or more frequency domain units of the first node, when the second node receives the power information of one or more frequency domain units of the first node, the second node can receive data of multiple frequency domain units faster.
[0120] If the second node does not receive the power information of one or more frequency domain units, the second node needs to use additional 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.
[0121] For example, the second node maintains a connection with the first frequency domain unit of the first node, and the second node receives the power information of the second frequency domain unit. The second frequency domain unit is a frequency domain unit for communication between the first node and the second node. Since the first frequency domain unit and the second frequency domain unit are used for communication between the first node and the second node, the second node determines the AGC setting of the second frequency domain unit according to the power information of the first frequency domain unit and the second frequency domain unit. 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 from that of the first frequency domain unit by 3 dB. Let the value of the AGC setting of the second node for the first frequency domain unit be AGC_1. If AGC_1 is in decibel value, then the AGC setting value of the second node for the second frequency domain unit is AGC_1+(30 - 33). If AGC_1 is in linear value, then 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 converting the decibel value to a linear value. Similarly, if AGC_1 is in linear value, and the power information of the first frequency domain unit and the second frequency domain unit are in decibel value, when calculating the AGC setting value of the second frequency domain unit, the power information also needs to be converted to a linear value first and then the AGC of the second power unit is adjusted, which will not be elaborated here.
[0122] Furthermore, the power information of one or more frequency domain units received by the second node can also be the frequency domain units of other nodes that communicate with the second node other than the first node.
[0123] Figure 19 is a schematic diagram of path loss measurement according to this embodiment, as Figure 19As shown in the figure, the second node measures the path loss between the second node and the third node, and the path loss between the second node and the first node. Let the path loss between the second node and the first node be PL_21 (in dB), and the path loss between the second node and the third node be PL_23 (in dB). The power information of the frequency domain unit between the second node and the first node is p_1 dBm. Let the AGC setting value of the second node receiving the first frequency domain unit be AGC_1 (linear value). Then, the second node can calculate that the AGC setting of the second frequency domain unit of the second node receiving the third node is AGC_1 + db2lin(p_1 - p_2 + PL_21 - PL_23) according to the power information p_2 dBm of the third node informed by the first node, where db2lin() represents converting the dB value to a linear value. If AGC, p_1, p_2, PL_21, and PL_23 are all in dB, then the AGC setting of the second frequency domain unit of the second node receiving the third node is AGC_1 + (p_2 - p_1 + PL_21 - PL_23). The conversion combinations between dB values and linear values in other cases will not be elaborated here.
[0124] The second node reports its capabilities to the first node through at least one of the following signaling: Radio Resource Control signaling, Media Access Control - Control Element (MAC CE for short), Uplink Control Information (UCI for short), and Non-Access Stratum (NAS) signaling.
[0125] The first node sends one or more packet information to the second node, and the power information of the frequency domain units within the group is equal or similar.
[0126] Similar power information means that the difference in the power information of the frequency domain units within the packet is less than a threshold value, which can be agreed upon or negotiated through signaling.
[0127] The second node sends a request message to the first node, requesting the packet situation of the frequency domain node power information from the first node.
[0128] The first node sends one or more packet information to the second node, and the path loss information of the frequency domain units within the group is equal or similar.
[0129] Similar path loss information means that the difference in the path loss between the frequency domain unit within the packet and the notified node is less than a threshold value, which can be agreed upon or negotiated through signaling.
[0130] The second node sends a request message to the first node, requesting the packet situation of the frequency domain node path loss information from the first node.
[0131] A signaling example for capability reporting is as follows:
[0132]
[0133] Among them, RAT indicates radio access technology, such as access technologies like UTRA (UMTS), EUTRA (LTE), NR, etc.
[0134] -vabcd indicates that the protocol version corresponding to the accessed radio access technology is abcd.
[0135] RAT_DC-Parameters-vabcd indicates an example of dual connectivity (DC) parameters for RAT technology.
[0136] RAT_DC-Parameters-vabcd::=SEQUENCE{
[0137] AGC-without-traning ENUMERATED{supported}OPTIONAL,
[0138] }
[0139] The above AGC-without-traning indicates that when receiving multiple carriers, the AGC of one or more carriers can be set without dedicated AGC training resources.
[0140] RAT_CA-Parameters-vabcd is an example of carrier aggregation (CA) parameters for 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 (abbreviated as CA) parameters for RAT technology.
[0145] Furthermore, the above signaling can also be associated with a specific carrier combination, which will not be elaborated here. The above signaling is a form of signaling for carrier aggregation or dual connectivity. Different forms of splitting or merging of UE-RAT-Capability-vabcd, RAT_DC-Parameters-vabcd, and RAT_CA-Parameters-vabcd can also be considered. 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 another example,
[0153] UE-RAT-Capability-AGC-without-traning::=SEQUENCE{
[0154] agc-without-traning ENUMERATED{supported}OPTIONAL,
[0155] }
[0156] An example of a 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 above CCPowerEnquiry-IEs carries power request information of one or more frequency domain units
[0161] The above CCPower-RequestList is a request list that lists the power information of one or more frequency domain units to be learned.
[0162] An example of the signaling for requesting power grouping information is as follows:

[0164] cc-PowerGroup-RequestList CCPowerGroup-RequestList
[0165] }
[0166] The above CCPowerGroupEnquiry-IEs carries the request information for the power grouping situation of one or more frequency domain units, where the CCPowerGroup-RequestList is a request list that lists the power grouping information of one or more frequency domain units to be learned.
[0167] Alternatively, the second node only submits a power grouping request message, and the request message itself does not carry a specific list of frequency domain units, requesting 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 the signaling for requesting path loss grouping information is as follows:
[0172] CCPathlossGroupEnquiry-IEs::= SEQUENCE{
[0173] cc-PathlossGroup-RequestList CCPowerGroup-RequestList
[0174] }
[0175] The above CCPathlossGroupEnquiry-IEs carry the request information of the path loss grouping situation of one or more frequency domain units. The CCPathlossGroup-RequestList in it is a request list, and this request list lists the path loss grouping information of one or more frequency domain units to be learned.
[0176] Alternatively, the second node only submits a path loss grouping request message, and the request message itself does not carry a specific list of frequency domain units, 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 a signaling for requesting information of a reference frequency domain unit is as follows:
[0181] PowerReferenceCCRequest ::= SEQUENCE {
[0182] cc-SetIndex INTEGER(0..M)
[0183] cc-IndexInOneCC-Set INTEGER(0..N)
[0184] }
[0185] Through the above signaling, a node can request a reference frequency domain unit. Specifically, it includes a CCset (component carrier set) index and a cc-IndexInOneCC-Set (component carrier index within the component carrier set), where M and N are integers greater than 0.
[0186] An example of a signaling for notifying the 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 above CCPowerInfo-IEs contains a list that includes the power information of one or more frequency domain units. The following is an implementation form of this list.

[0200] }
[0201] The above cc-SetIndex is the index of a set of frequency domain units, taking integer values from 0 to M, where M is greater than 0.
[0202] The above cc-IndexInOneCC-Set is the index of a frequency domain unit within a set of frequency domain units, taking integer values from 0 to N, where N is greater than 0.
[0203] The above powerInfo is the specific power information. The power information can be power quantities such as the aforementioned power value, power spectral density, EPRE, EIRP, etc., or can also be the offset relative to a reference frequency domain unit.
[0204] A notification signaling for the power grouping information of frequency domain units is as follows:
[0205] CCPowerGroupInfo-IEs ::= SEQUENCE {

[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. The grouping information in the list is specifically indicated by PowerGroupList, and PowerGroupList includes a group index. Optionally, PowerGroupList can also include a component carrier set index to indicate the component carrier set included in a power group.

Optionally, PowerGroupList can also include a power deviation delta_power, and this field 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 type of capability reporting, for example, capability reporting is performed through the signaling of MAC CE.
[0218] The MAC CE reports that a node has the capability to set one or more carriers without performing AGC training as shown in Table 1.
[0219] Table 1
[0220] AGC setting without AGC training True
[0221] A request message, for example, requests the path loss information of one or more frequency domain units through signaling of MAC CE, as shown in Table 2.
[0222] Table 2
[0223] CCset index1 CC_index1 CCset_index1 CC_index2 … … CCset_indexM CC_index1 … … CCset_indexM CC_indexN
[0224] MAC CE requests the power information of one or more frequency domain units, as shown in Table 3.
[0225] Table 3
[0226] CCset index1 CC_index1 CCset_index1 CC_index2 … … CCset_indexM CC_index1 … … CCset_indexM CC_indexN
[0227] A row in Table 3 is divided into two fields. The first field indicates the CCset (component carrier set) index, and the second field indicates the CC (component carrier) index within a CCset.
[0228] Another request method is to carry only the CCset, as shown in Table 4.
[0229] Table 4
[0230] CCset index1 CCset_index2 … CCset_indexM
[0231] Alternatively, the request carries only the CC_index. For example, there is only one CCset between the first node and the second node, and at this time, the CC_index is the CC_index of this CCset.
[0232] The above-mentioned signaling form requests the power information of several CCsets. A CCset contains one or more CCs, which is a specific embodiment of the frequency domain unit described in the text.
[0233] Another request method is to carry a reference frequency domain unit, as shown in Table 5.
[0234] Table 5
[0235] CCset index1 CC_indexI CCset_index1 CC_index2 … … CCset_indexM CC_index1 … … CCset_indexM CC_indexN CCset_indexM_Ref CC_index_Ref
[0236] The power request information carrying the reference frequency domain unit can be to carry only the CCset index or the CC_index.
[0237] MAC CE is a signaling for a node to inform another node of the reference frequency domain unit, as shown in Table 6.
[0238] Table 6
[0239] CCset index1 CC_index1
[0240] Alternatively, a node only notifies another node of the set index where the reference frequency domain unit is located as shown in Table 7.
[0241] Table 7
[0242] CCset index1
[0243] The reference frequency domain units notified in Table 7 carry only one component carrier set. The two nodes can agree that the CC with the smallest CCindex in the CCset is the reference frequency domain unit, or agree that the primary serving cell in the CCset is the reference frequency domain unit. The MAC CE is a signaling for a node to inform another node of the power information of one or more frequency domain units, as shown in Table 8.
[0244] Table 8
[0245] CCset index_1 CC_index_1 Power_info_1 CCset_index_1 CC_index_2 Power_info_2 … … … CCset_index_M CC_index_1 … … … … CCset_index_M CC_index_N Power_info_K
[0246] Power_info1ˉPower_infoK in Table 9 is a power value or power spectral density or EPRE or EIRP. Further, the power information may also be power information associated with a beam, a time unit, a modulation scheme, a waveform, and a transmission mode. The power information may also be an index value of a power level. For example, the power value is divided into several levels according to a step value, and each power level corresponds to an index.
[0247] As shown in Table 9, the power ranges corresponding to different indexes are given.
[0248] Table 9
[0249] Power_info_1 Power_Range_1 <= power < Power_Range_2 Power_info_2 Power_Range_2 <= power < Power_Range_3 … … Power_info_K Power_Range_K <= power < Power_Range_K + 1
[0250] The signaling for notifying the power information of one or more frequency domain units of a beam is shown in Table 10. Each row corresponds to the power information of one frequency domain unit of a beam.
[0251] Table 10
[0252] CCset index_1 CC_index_1 TCI_state_ID1 Power_info_1 CCset_index_1 CC_index_2 TCI_state_ID2 Power_info_2 … … … … CCset_index_M CC_index_1 … … … … … … CCset_index_M CC_index_N TCI_state_IDJ Power_info_K
[0253] The MAC CE requests the power grouping of one or more frequency domain units as shown in Table 11.
[0254] Table 11
[0255] CCset index1 CC_index1 CCset_index1 CC_index2 … … CCset_indexM CC_index1 … … CCset_indexM CC_indexN
[0256] One row in Table 11 is divided into two fields. The first field indicates the CCset (component carrier set) index, and the second field indicates the CC (component carrier) index within a CCset.
[0257] Another request method is to carry only the CCset, for querying the power group information of one or more frequency units, as shown in Table 12. Or the request signaling carries only the CC_index. For example, if there is only one CCset between the first node and the second node, then the CC_index is the CC_index of this CCset. Or if the first node and the second node do not define a CCset, then the CC_index is the CC_index without considering the CCset.
[0258] Table 12
[0259] CCset index1 CCset_index2 … CCset_indexM
[0260] The above-mentioned signaling form requests the power information of several CCsets. One CCset contains one or more CCs, which is a specific implementation of the frequency domain units described in the text.
[0261] The MAC CE is a signaling for a node to inform another node of the power grouping of one or more frequency domain units, as shown in Table 13. The power grouping in Table 13 can also be a power grouping associated with a beam, a time unit, a modulation scheme, a waveform, and a transmission mode.
[0262] Table 13
[0263] CCset index_1 CC_index_1 Group_1 CCset_index_1 CC_index_2 Group_2 … … … CCset_index_M CC_index_1 … … … … CCset_index_M CC_index_N Group_K
[0264] The power grouping of one or more frequency domain units can also be a power grouping indicating a component carrier set. This notification method notifies the power grouping of frequency domain units according to the component carrier set, as shown in Table 14.
[0265] Table 14
[0266] CCset index_1 Group_1 CCset_index_2 Group_2 … … CCset_index_M Group_K
[0267] In Table 14, the correspondence between the CCset_index and the Group is an example. In actual situations, different CCset_indexes may correspond to the same Group.
[0268] The above Tables 1-14 only give the fields related to this application. In actual implementation, there may also be placeholder bits.
[0269] For the above-mentioned ability reporting, power information request, path loss information request, etc., the MAC CE introduces LCIDvalue for the MAC CE transmission involved in the above Tables 1-14.
[0270] Table 15 is for the MAC CE LCIDvalue of ability reporting, power request, power information notification, reference frequency domain unit request, and reference frequency domain unit notification.

[0272] Codepoint / index LCID values Index1 Capability reporting Index2 Power request Index3 Path loss request Index4 Reference frequency domain unit request Index5 Reference frequency domain unit notification Index6 Power information notification Index7 Path loss information notification
[0273] The second node sends a capability reporting message to the first node via UCI and reports the capability via the PUCCH of 5G NR.
[0274] The second node uses one cyclic shift (CS, Cyclic Shift) of the PUCCH to inform the first node of the capability of setting the AGC that supports one or more frequency domain units.
[0275] The second node requests the power information of one or more frequency domain units from the first node via UCI.
[0276] The second node transmits the power information of one or more frequency domain units to the first node via one cyclic shift of the PUCCH. Specifically, the cyclic shift of the PUCCH can indicate the frequency domain unit. An example is as follows. The signaling for requesting the power information of one or more frequency domain units using different cyclic shifts is shown in Table 16.
[0277] Table 16
[0278] Cyclic shift (CS)1 Cyclic shift (CS)2 … Cyclic shift (CS)N CC_set1 CC_set2 CC_setN
[0279] Furthermore, the second node can use two or more sequences to report the power information of one or more frequency domain units to the first node. For example, different cyclic shifts of the first sequence are used to indicate CC_set, and the cyclic shift of the second sequence is used to indicate CC_index.
[0280] The second node requests the power information of one or more frequency domain units using several bits of UCI.
[0281] For example, the bits of UCI are divided into two types of fields. One type of field indicates the carrier set CCset index, and the other type of field indicates the CC index within the carrier set CCset.
[0282] Two fields are used to indicate the CCset index and the CC index within CCset respectively, as shown in Table 17.
[0283] Table 17
[0284] CCset index bit combination CC index bit combination within CCset aN-1,…,a1,a0 bM-1,…,b1,b0
[0285] Where ai (i ∈ [0, 1,..., N - 1]) and bj (j ∈ [0, 1,..., M - 1]) take values of 0 or 1, which represent 2^N set index values and 2^N component carrier or cell (frequency domain unit) index values within the set.
[0286] The second node sends the desired reference frequency domain unit to the first node via UCI.
[0287] The second node sends at least one of CC_set and CC_index to the first node by using the cyclic shift of UCI or several bits of UCI. 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 different component carriers or cells (frequency domain units) indexed by cc_index, 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 the desired reference frequency domain unit is located, and 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 by a pre-agreed method.
[0288] The first node notifies the power information of one or more frequency domain units through DCI.
[0289] Among them, one field of DCI is used to notify the frequency domain unit index, and another field of DCI is used to notify the power information of the frequency domain unit.
[0290] Furthermore, the field for notifying the frequency domain unit index can be further divided into a set index and a frequency domain unit index within the set.
[0291] Furthermore, the first node notifies the reference frequency domain unit through a field of DCI. Specifically, it can notify at least one of the following: the index of the reference frequency domain unit, the frequency domain unit index where the reference frequency domain unit is located, and the cell group.
[0292] The power information of the frequency domain unit is notified by the index value. For example, the index value is represented by N bits, and the number of power levels that these N bits can represent is 2 to the power of N (2^N). These 2^N power levels can be pre-agreed power levels or power levels reached through interaction between nodes, as shown in Table 10 for example.
[0293] The power range of the power levels is shown in Table 18.
[0294] Table 18
[0295] Power_level_1 Power_Range_1 <= power < Power_Range_2 Power_level_2 Power_Range_2 <= power < Power_Range_3 … … Power_level_K Power_Range_K <= power < Power_Range_K + 1
[0296] The second node sends a power grouping request for one or more frequency domain units to the first node by using the cyclic shift (CS, Cyclic Shift) of PUCCH.
[0297] Table 19 shows the signaling for requesting one or more frequency domain unit power groups using different cyclic shifts.
[0298] Table 19
[0299] Cyclic shift (CS)1 Cyclic shift (CS)2 … Cyclic shift (CS)N CC_set1 CC_set2 CC_setN
[0300] Furthermore, the second node may use two or more sequences to request the first node for power grouping information of one or more frequency domain units, 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.
[0301] The second node sends one or more frequency-domain unit path loss grouping requests to the first node by using a cyclic shift (CS) of the PUCCH.
[0302] Table 20 shows the signaling for requesting one or more frequency domain unit path loss groups using cyclic shift.
[0303] Table 20
[0304] Cyclic shift (CS)1 Cyclic shift (CS)2 … Cyclic shift (CS)N CC_set1 CC_set2 CC_setN
[0305] Furthermore, the second node may use two or more sequences to request path loss grouping information of one or more frequency domain units from 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.
[0306] The first node notifies power grouping information of one or more frequency domain units via DCI, wherein one field of the DCI is used to notify the frequency domain unit index, and another field of the DCI is used to notify the power grouping information of the frequency domain unit.
[0307] Furthermore, the field used to notify the frequency domain unit index can be divided into a set index and an intra-set frequency domain unit index.
[0308] Furthermore, the first node notifies a reference power deviation delta_power through a field of the DCI, to indicate that the power deviation in a group is smaller than the aforementioned power deviation delta_power.
[0309] The first node notifies the path loss grouping information of one or more frequency domain units through DCI.
[0310] Among them, one field of the DCI is used to notify the frequency domain unit index, and another field of the DCI is used to notify the path loss grouping information of the frequency domain unit.
[0311] Further, the field for notifying the frequency-domain unit index can be further divided into a set index and a frequency-domain unit index within the set.
[0312] Further, the first node notifies the path loss deviation delta_pathloss of the path loss group through a field of the DCI, indicating that the path loss deviation amount within a group is less than the aforementioned path loss deviation delta_pathloss.
[0313] The names and formats of the above signaling are only examples for illustrating the specific information used for application or notification in this embodiment, and do not impose any limitation on this application.
