[0053] To facilitate the understanding of the transmit power control method provided in the embodiments of this application, the following related technologies are first explained:

[0054] I. Backscatter Communication (BSC)

[0055] Backscatter communication refers to the backscatter communication device using radio frequency signals in other devices or the environment for signal modulation to transmit its own information.

[0056] In some embodiments, the backscatter communication device may include at least one of the following:

[0057] Device A, which refers to the backscatter communication device in traditional Radio Frequency Identification (RFID). Generally, it is a tag and belongs to a Passive-IoT device.

[0058] Device B, which refers to a semi-passive IoT device. This type of device has a certain amplification ability for downlink reception or uplink reflection.

[0059] Device C, which refers to a device with active transmission ability (active device). This type of IoT device can send signals to a reader without relying on the reflection of the incident signal.

[0060] The energy source of the above backscatter communication device can come from the environment, such as ambient Radio Frequency (RF) signals, thermal energy, kinetic energy, wind energy, etc. It can also be called an Ambient IoT device.

[0061] In some embodiments, as Figure 2 shown, a simple implementation of backscatter communication is as follows: when the tag needs to send '1', the tag reflects the incident carrier signal; when the tag needs to send '0', it does not reflect.

[0062] In some embodiments, as Figure 3 shown, the backscatter communication device controls the reflection coefficient Γ of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve signal modulation. Among them, the reflection coefficient Γ of the signal can be calculated by the following formula:

[0063] Γ = (Z_1 - Z_0) / (Z_1 + Z_0) = |Γ|e^(jθ_T)

[0064] where Z_0 is the antenna characteristic impedance and Z_1 is the load impedance. Assuming the incident signal is S_in(t), the output signal is S_out(t) = S_in(t)|Γ|e^(jθ_T). Therefore, corresponding amplitude modulation, frequency modulation, or phase modulation can be achieved by reasonably controlling the reflection coefficient.

[0065] II. Modulation methods that may be used for low-power signals

[0066] 1) OOK

[0067] For the OOK modulation method, there are two generation methods. One is the multi-carrier (MultiCarrier OOK, MC-OOK) signal based on the OFDM architecture, and the other is the single-carrier OOK signal.

[0068] For the multi-carrier OOK signal based on the OFDM architecture, its design idea is not to change the transmitting end architecture of the existing base station. Therefore, appropriate data is sent on the OFDM subcarriers to make it present a square wave signal in the time domain, and its generation framework is as Figure 4 shown.

[0069] For the single-carrier OOK signal, it controls the turning on and off of the incident carrier or continuous wave (CW) with a unipolar non-return-to-zero code sequence. Its modulation method is simple and suitable for low-power signals.

[0070] 2) O-QPSK or DBPSK

[0071] For the active tag, offset quadrature phase shift keying (O-QPSK) or differential binary phase shift keying (DBPSK) modulation can be used to send data. These two modulation methods belong to the constant envelope modulation technology. The introduction of these two modulation methods is as follows:

[0072] The modulation process of O-QPSK can be described as follows: The serially input binary data stream is divided into two different paths, the I path and the Q path, for transmission. Among them, "I" is the component that is "in-phase" with the data waveform, and "Q" is the part that is "orthogonal" to the data waveform. That is, the even bits of the original input data are assigned to the I path, and the odd bits are assigned to the Q path, and it is ensured that the code streams of the in-phase and orthogonal branches are staggered by half a symbol period in time. Then, the carrier is modulated with the data of the I path and the Q path respectively, that is, one of the four discrete phase changes is used to represent a symbol (a pair of bits) to be transmitted.

[0073] BPSK is similar to QPSK, and both use phase to carry symbol information. For example, when the input symbol is "1", the output of the baseband modulator is 1 (phase 0 degrees); when the input symbol is "0", the output of the baseband modulator is -1 (phase 0 degrees). However, BPSK has a phase ambiguity problem. The so-called phase ambiguity means that the recovered digital information will change from "0" to "1" or from "1" to "0", resulting in an incorrect recovery. This phenomenon of incorrect recovery in the receiving system due to the inversion of the local reference carrier is called the "phase ambiguity" phenomenon. To solve this problem, differential coding is introduced, so that the decoding at the receiving end is judged according to the change of the phase, rather than according to the absolute value of the phase. This is DBPSK.

[0074] It is worth noting that in order to obtain better link performance and anti-interference performance, the original bit information is extended by means of extended sequences and / or coding. Common processing methods include, for example, Figure 5 the O-QPSK transmission and extended sequence shown in Figure 6 , and the DBPSK modulation and extended sequence shown in

[0075] 3) MSK and GMSK Modulation

[0076] Minimum Shift Keying (MSK) is a constant envelope continuous phase modulation, and its modulation method is developed from binary Frequency Shift Keying (FSK) modulation. In FSK, the carrier frequency changes randomly with the modulation signal, which is usually "0" or "1", and the phase after modulation is discontinuous. If the phase is continuous, it is called Continuous Phase Frequency Shift Keying (CP-FSK). The so-called MSK modulation method is a special form of CP-FSK with a modulation index of 0.5. The MSK modulation principle can be expressed by the following formula:

[0077]

[0078] Let where θ k is called the additional phase function to ensure the phase continuity between different symbols, ω c t is the carrier angular frequency, T s is the symbol width; a k is the phase constant of the k-th symbol. The modulation block diagram of MSK is as shown in Figure 7 .

[0079] Since the phase path of MSK is a curve and its power spectrum side lobe deviates from the center frequency when observed on a spectrum analyzer and the attenuation is slow. Therefore, a Gaussian filter is added before MSK modulation to make up for the shortcomings of MSK, so as to achieve the purpose of improving the attenuation performance. Therefore, this modulator is called Gaussian Minimum Shift Keying (GMSK). As can be seen from the GMSK signal modulation principle diagram shown in Figure 8 , GMSK modulation is to add a Gaussian low-pass filter before the MSK modulator, so that the signal is smoother and the side lobe attenuation performance of the power spectrum is significantly improved. After MSK modulation, symbol data, that is, the I channel and the Q channel, come out, and finally the GMSK expression is as follows:

[0080]

[0081] Among them, A represents the signal envelope, ω c represents the carrier angular frequency, represents the information phase.

[0082] III. Classification and Characteristics of AIoT Devices in 3GPP

[0083] In the AIoT research of 3GPP R19, environmental IoT devices are characterized according to their energy storage capacity and the ability to generate radio frequency signals for transmission. The AIoT device has one of the following energy storage capabilities:

[0084] Storage Capacity 1: No ability to store energy;

[0085] Storage Capacity 2: Energy can be stored up to E1 or E2 joules, where it is possible that E1 = E2;

[0086] Storage Capacity 3: Energy can be stored up to E2 joules.

[0087] Relying on these storage capacities, the study considered the following set of environmental IoT devices:

[0088] Device A: No energy storage, no independent signal generation / amplification, i.e., backscatter transmission;

[0089] Device B: Has energy storage, no independent signal generation, i.e., backscatter transmission. The use of stored energy can include amplification of the reflected signal;

[0090] Device C: Has energy storage, has independent signal generation, i.e., active radio frequency components for transmission.

[0091] IV. Connection Topology and Deployment Scenarios of AIoT Devices

[0092] 1) As Figure 9a shown, in the connection topology 1 of the AIoT device, the AIoT device and the Base Station (BS) establish a two-way direct connection.

[0093] 2) As Figure 9b shown, in the connection topology 2 of the AIoT device, the AIoT device and an intermediate node establish a two-way connection. The intermediate node can be a relay node, IAB node, User Equipment (UE), repeater, etc. The intermediate node transmits the data and / or signaling of the AIoT device to the base station, or the intermediate node transmits the data and / or signaling of the base station to the AIoT device.

[0094] 3) As Figure 9c and Figure 9dAs shown in the connection topology 3 of the AIoT device, the AIoT device sends data / signaling to the base station and receives data / signaling from an auxiliary node; or the AIoT device receives data / signaling from the base station and sends data / signaling to an auxiliary node. Among them, the auxiliary node can be a relay, an IAB node, a UE, a repeater, etc.

[0095] 4) As Figure 9e shown in the connection topology 4 of the AIoT device, the AIoT device and the UE establish a bidirectional direct connection.

[0096] It should be noted that the ultra-low power consumption communication module in the embodiments of the present application is similar to the above-mentioned AIoT device, except that the communication device with the ultra-low power consumption communication module also has a main communication module at the same time. For the convenience of description, the AIoT device mentioned in the following embodiments of the present application refers to the ultra-low power consumption communication module.

[0097] V. Power Control of NR

[0098] The NR protocol defines the power control of the uplink channel or signal (for example: Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Sounding Reference Signal (SRS), and Physical Random Access Channel (PRACH)).

[0099] 1) Power control of PUSCH:

[0100] If the UE configures the parameter set with index j and the PUSCH power control process with index l, and sends PUSCH on the active uplink (UL) bandwidth part (BWP) b of the carrier f in the serving cell c, then the UE will use the PUSCH transmission power P PUSCH,b,d,c (i, j, q d , l) is determined as:

[0101]

[0102] Among them, the parameter j is used to represent the parameter configuration index of open-loop power control (for example, j = 0 represents the PUSCH in RACH, j = 1 represents the PUSCH related to Configured Grant, and j >= 2 represents the PUSCH of dynamic grant), and the parameter l is used to represent the process index of closed-loop power control, q d represents the reference signal index. P CMAX，f，c (i) is the maximum transmit power of the UE at time i, which is defined for the carrier and cell; P O_PUSCH,b,f，c (j) is the target receive power (on a resource block (RB) with a 15 kHz subcarrier spacing (SCS)) of the open-loop control configuration index j, which is defined for the BWP, carrier, and cell; PL b,f，c (q d ) is the estimated downlink path loss of the UE using the reference signal q d , which is defined for the BWP, carrier, and cell; α b，f，c (j) is the partial path loss compensation factor defined by the open-loop control configuration index j, which is defined for the BWP, carrier, and cell; Δ TF，b，f，c (i) defines the transmit power required for each RE of the UE at time i, which is defined for the BWP, carrier, and cell. It is only used for single-layer transmission and is 0 for multi-layer transmission; is the number of RBs of the PUSCH at time i. Combining with the SCS determines the total bandwidth of the PUSCH, which is defined for the BWP, carrier, and cell; f b，f，c (i, l) is the bias value introduced by the closed-loop power control process l at time i, which is the sum of the power adjustment values indicated by the transmit power control (TPC) commands at past times, that is, where, δ PUSCH,b,f,c (m, l) is the mth TPC command indicated power adjustment value of the lth closed-loop power control process, all of which are defined for the BWP, carrier, and cell.

[0103] 2) Power control for PUCCH:

[0104] If the UE uses the PUCCH power control process with index l and sends the PUCCH on the active UL BWP b of the carrier f in the primary cell c, then the UE determines the PUCCH transmit power P PUCCH,b,f,c (i, q u , q d , l) as:

[0105]

[0106] where q u is the index of PUCCH (the UE may need to transmit multiple PUCCHs simultaneously).

[0107] It should be noted that the power control of the above PUCCH and the power control of PUSCH have the following differences:

[0108] i) There is no partial path loss compensation factor;

[0109] ii) P O_PUCCH,b,f,c (q u ) is the target received power of the q u th PUCCH, which is defined for the BWP, carrier, and cell;

[0110] iii) Δ F_PUCCH (F) represents the power control offset that needs to be introduced for different PUCCH formats (F). For example, if the power control offset for different PUCCH formats is introduced, then Δ F_PUCCH (F0) corresponds to PUCCH format 0, Δ F_PUCCH (F1) corresponds to PUCCH format 1, Δ F_PUCCH (F2) corresponds to PUCCH format 2, Δ F_PUCCH (F3) corresponds to PUCCH format 3, Δ F_PUCCH (F4) corresponds to PUCCH format 4; otherwise, Δ F_PUCCH (F) = 0.

[0111] iv) g b，f，c (i, l) is the bias value introduced by the closed-loop power control process / at time i, which is the sum of the power adjustment values indicated by the TPC commands at past times.

[0112] 3) Power control for SRS:

[0113] If the UE uses the SRS power control process with index l and transmits SRS based on the configuration of the SRS resource set on the active UL BWP b of the carrier f in the serving cell c, then the UE determines the SRS transmission power P SRS,b,f,c (i, q s , l) in the SRS transmission opportunity i as:

[0114]

[0115] where PL b,f，c (q d ) represents the estimated downlink path loss based on the reference signal q d .

[0116] It should be noted that the power control of the above SRS and the power control of PUSCH include the following differences:

[0117] i) P O_SRS,b,f，c (q s ) is the target received power of the SRS of the q-th SRS resource set, which is defined for the BWP, carrier, and cell; s

[0118] ii) M SRS,b,f，c (i) is the number of RBs of the SRS at time i. Combining with the SCS determines the total bandwidth of the SRS, which is defined for the BWP, carrier, and cell;

[0119] iii) α SRS,b,f，c (q s ) is the partial path loss compensation factor of the SRS resource set q, which is defined for the BWP, carrier, and cell; s

[0120] iv) h b,f，c (i, l) is the bias value introduced by the closed-loop power control process l at time i, which can be the same as the power control bias value of the PUSCH, or (when there is no PUSCH transmission) is the sum of the power adjustment values indicated by the TPC commands at past times.

[0121] 4) Power control of the PRACH:

[0122] The UE determines the transmission power P of the physical random access channel (PRACH) on the active UL BWP b of the carrier f of cell c based on the downlink (DL) reference signal (RS) of cell c in the transmission occasion i PRACH,b,f，c is defined as:

[0123] P PRACH,b,f,c (i) = min{P CMAX,f,c (i), P PRACH,target,f,c + PL b,f,c}

[0124] It should be noted that the power control of the above PRACH and the power control of PUSCH include the following differences:

[0125] i) P PRACH,target,f,c is the target received power of the PRACH, which is given by the parameter: PREAMBLE_RECEIVED_TARGET_POWER, and is defined for the BWP, carrier, and cell;

[0126] ii) PL b,f，c ​​It is the downlink path loss estimated by the UE using a uniquely associated reference signal (referenceSignalPower - higher layer filtered RSRP in dBm), and is defined for the BWP, carrier, and cell.

[0127] As can be seen from the above, the transmit power control method defined by NR is designed based on the assumption of multi - carrier signals such as OFDM / DFT - S - OFDM and the direct connection topology between the UE - gNB / IAB. However, the ultra - low - power communication module may use single - carrier signals such as OOK / ASK / FSK, and the connection topology is not limited to the simple direct - connection topology. For example, it may be the separated architecture of Topology 3. Therefore, the transmit power control method in the related technology is not applicable to the power control of the ultra - low - power communication module.

[0128] For example: The power control of PUSCH, PUCCH, and SRS needs to consider the signal format, that is, the bandwidth occupied by the signal (number of RBs and SCS), and the number of bits (Bits PerRE) that each resource element (RE) needs to carry. And the occupied bandwidth is calculated based on the assumption of OFDM signals. The ultra - low - power communication module may need to use new signals, and possible signal types include: OOK, ASK, FSK, GMSK, O - QPSK, DBPSK, etc., and these signals are all single - carrier - modulated signals. The actual occupied bandwidth of different signals and the number of bits required for each symbol will affect the calculation of the transmission power. The power calculation formula of NR in the related technology is calculated based on the OFDM signal with a certain sub - carrier spacing (such as 15 kHz), and it cannot be directly used for the power calculation of single - carrier signals. Therefore, there is a lack of a transmit power control method for ultra - low - power communication modules in the related technology.

[0129] Among them, the definition of single - carrier modulation is: a modulation technique that uses only one carrier within a fixed frequency band. For single - carrier modulation, a symbol can carry at most 2 orthogonal signals (divided into I and Q channels). When the symbol rate and transmission pulse are fixed, the bandwidth occupied by the single - carrier signal is also fixed. For example, assuming a double - sideband ASK signal, if the transmission pulse is an ideal time - domain sinc signal, then the bandwidth occupied by the signal is 1 / T s , where, T s is the time width of 1 pulse and also the time length of 1 modulation symbol.

[0130] VI. Non - IoT Devices Integrated with Ultra - Low - Power Communication Modules

[0131] A very low-power communication module is generally applied alone to terminals with high requirements for power consumption, complexity, and battery life, such as Internet of Things (IoT) terminals. An extended application scenario is to apply the very low-power communication module to non-IoT devices such as mobile phones, including the terminal and the network-side device. In this way, both the main communication module and the very low-power communication module are available on the device. Among them, the main communication module has high rate and spectral efficiency, but also high power consumption. If it is turned on for a long time, it will reduce the battery life of the device and is suitable for transmitting a large amount of data in a short time. In contrast, the very low-power communication module has relatively low rate and spectral efficiency, but very low power consumption, and is suitable for transmitting a small amount of data for a long time, or for monitoring control plane signaling to avoid or reduce the additional delay caused by Discontinuous Reception (DRX). Figure 10 Figure 10 shows a schematic diagram of information interaction between a terminal with a main communication module and a very low-power communication module and a network-side device. The two devices exchange the first information and the second information through the very low-power communication module, and then perform information interaction with the main communication module within the device, such as waking up the main communication module by the very low-power communication module for further operations, etc.

[0132] In the embodiments of the present application, based on the transmission signal and topology structure characteristics of the non-IoT device integrated with the very low-power communication module, a method for controlling the transmission power of the very low-power communication module and a configuration method for power control of the very low-power communication module and the main communication module are provided.

[0133] For the convenience of description, the following terms in the embodiments of the present application are first explained:

[0134] 1) The first communication module, that is, the main communication module, which is also called MR. The main communication module generally refers to a module that supports traditional communication methods (such as 4G, 5G, etc.), for example, a module that supports OFDM communication (including uplink and / or downlink).

[0135] 2) The second communication module, that is, the very low-power communication module, which is also called or LR. The very low-power communication module refers to a module that supports sending signals in a backscatter manner (such as Device A or Device B in AIoT) or sending signals in a low-power active carrier generation manner (such as Device C in AIoT) and / or supports a low-power receiving module (such as a low-power wake-up receiver).

[0136] Optionally, the very low-power communication module can also support energy harvesting (harvesting energy from light, solar energy, wireless signals, etc.).

[0137] It should be noted that for the way of sending signals by backscatter, the excitation source signal can be generated by the terminal itself with a very low power consumption communication module or by other devices. For example, the excitation source signal is generated by the main communication module on the first device, or the excitation source signal is generated by other devices.

[0138] It is worth noting that the power consumption of the very low power consumption communication module is significantly lower than that of the main communication module. For example, the power consumption of the very low power consumption communication module is generally from dozens of microwatts to hundreds of microwatts, while the power consumption of the main communication module is generally from dozens of milliwatts to thousands of milliwatts; the cost of the very low power consumption communication module is also significantly lower than the cost of the main communication module.

[0139] Next, in conjunction with the accompanying drawings, the transmission power control method, transmission power control device and related equipment provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0140] Refer to Figure 11 , a transmission power control method provided by an embodiment of the present application, the execution subject of which is the first device, such as Figure 11 As shown, the transmission power control method includes the following steps:

[0141] Step 111, the first device obtains first information. The first device includes a first communication module and a second communication module, and the second communication module is a very low power consumption communication module.

[0142] Step 112, the first device determines a first target transmission power of the first communication module and a second target transmission power of the second communication module according to the first information; wherein, the first target transmission power is used for the first communication module to send a first signal, and the second target transmission power is used for the second communication module to send a second signal.

[0143] In some embodiments, after the first device determines the first target transmission power, the first device controls the first communication module to send the first signal according to the first target transmission power.

[0144] Optionally, the first target transmission power may be the transmission power on specified time-frequency resources. At this time, the first device may control the first communication module to send the first signal according to the first target transmission power on the time-frequency resources corresponding to the first target transmission power.

[0145] In some embodiments, after the first device determines the second target transmission power, the first device controls the second communication module to send the second signal according to the second target transmission power.

[0146] Optionally, the second target transmission power may be the transmission power on specified time-frequency resources. In this case, the first device may control the second communication module to transmit a second signal at the second target transmission power on the time-frequency resources corresponding to the second target transmission power.

[0147] The first device in the embodiments of the present application refers to a device equipped with a first communication module and a second communication module, which may specifically be a network-side device or a terminal. For ease of description, in the embodiments of the present application, the first device is usually taken as an example of a terminal for illustration.

[0148] It should be noted that in an actual application scenario, the execution order of the above step 113 and step 114 may be to execute step 113 first and then step 114, or to execute step 114 first and then step 113, or to execute step 113 and step 114 simultaneously. Figure 11 The shown flowchart of the transmission power control method is only an example and does not limit the execution order of step 113 and step 114.

[0149] In some embodiments, the first signal transmitted by the first communication module may be an OFDM signal, and the second signal transmitted by the second communication module may be a single-carrier signal.

[0150] Of course, in addition to OFDM signals and single-carrier signals, the above first signal and second signal may also be a combination of other types of signals, which is not specifically limited herein.

[0151] In some embodiments, the above first information may directly indicate the first target transmission signal and the second target transmission signal, or may indicate the relevant information for determining the first target transmission signal and the second target transmission signal.

[0152] In some embodiments, the ways for the first device to obtain the first information may include at least one of the following:

[0153] Receiving at least part of the first information configured by the network side (second device);

[0154] Obtaining at least part of the first information stored or calculated locally. For example, the terminal obtains the first adjustment amount configured by the network side and knows the first target transmission power of the first communication module locally;

[0155] Obtaining at least part of the first information agreed upon by the protocol.

[0156] In an embodiment of the present application, for a first device that simultaneously has a primary communication module (i.e., the first communication module) and an extremely low-power communication module (i.e., the second communication module), power control can be performed on the two communication modules on the first device based on first information, so that the first target transmit power of the first signal transmitted based on the primary communication module on the first device and the second target transmit power of the second signal transmitted based on the extremely low-power communication module on the first device are more flexible, improving the communication performance of the first device.

[0157] In some embodiments, the first information includes at least one of the following:

[0158] The first target transmit power and the first adjustment amount of the first communication module, and the second target transmit power is determined based on the first target transmit power and the first adjustment amount;

[0159] The first parameter and the second adjustment amount of the first communication module, and the second parameter is determined based on the first parameter and the second adjustment amount;

[0160] The second target transmit power and the third adjustment amount of the second communication module, and the first target transmit power is determined based on the second target transmit power and the third adjustment amount;

[0161] The second parameter and the fourth adjustment amount of the second communication module, and the first parameter is determined based on the second parameter and the fourth adjustment amount;

[0162] The first parameter and the second parameter;

[0163] Wherein, the first parameter includes a parameter for determining the first target transmit power; the second parameter includes a parameter for determining the second target transmit power.

[0164] Embodiment 1: The first information includes the first target transmit power and the first adjustment amount of the first communication module.

[0165] In this embodiment, the difference between the first target transmit power of the first communication module and the second target transmit power of the second communication module and the corresponding first target transmit power can be used as the first adjustment amount. In this way, by indicating the first adjustment amount, the corresponding second target transmit power can be determined with reference to the first target transmit power.

[0166] For example: The network indicates or agrees on a power adjustment amount Δ MR->LR , and the second target transmit power of a certain target transmission channel (such as PUSCH, PRACH, SRS, PUCCH, etc.) of LR is the sum of the first target transmit power of the corresponding channel of the primary communication module and the adjustment amount Δ MR->LR .

[0167] Specifically, P LR,PUSCH,b′,f′,c′ (i′, j′, q′ d , l′) = P MR,PUSCH,b,f,c (i, j, q d , l) + Δ MR->LR ;

[0168] P LR,PUCCH,b′,f′,c′ (i′, q u ′, q′ d , l′) = P MR,PUCCH,b,f,c (i, q u , q d , l) + Δ MR->LR ;

[0169] P LR,SRS,b′,f′,c′ (i′, q′ s , l′) = P MR,SRS,b,f,c (i, q s , l) + Δ MR->LR ;

[0170] P LR,PRACH,b′,f′,c′ (i′) = P MR,PRACH,b,f,c (i) + Δ MR->LR ;

[0171] Among them, the parameter i is the symbol / time index; the parameter j is the parameter configuration index for open-loop power control (for example, j = 0 represents PUSCH in RACH, j = 1 represents PUSCH related to Configured Grant, j >= 2 represents PUSCH for dynamic grant); the parameter l is the process index for closed-loop power control; q d is the reference signal index; q u is the index of PUCCH; q s is the SRS resource set index; c is the serving cell index; f is the carrier index; b is the Bandwidth Part (BWP) index.

[0172] The meanings of b′, c′, f′, i′, j′, q′, l′ above are similar to those of b, c, f, i, j, q, l above. The difference is that b′, c′, f′, i′, j′, q′, l′ are used for LR, and b, c, f, i, j, q, l are used for MR.

[0173] In some embodiments, b, c, f, i, j, q, l of MR can be the same as b′, c′, f′, i′, j′, q′, l′ of LR.

[0174] In some other embodiments, at least one of b, c, f, i, j, q, l of MR and b′, c′, f′, i′, j′, q′, l′ of LR may be different. In this case, the first device may obtain the association relationship between b, c, f, i, j, q, l of MR and b′, c′, f′, i′, j′, q′, l′ based on network - side indication or protocol convention, so as to determine the second target transmission power of the associated b′, c′, f′, i′, j′, q′, l′ with reference to the first target transmission power of b, c, f, i, j, q, l, or determine the first target transmission power of the associated b, c, f, i, j, q, l with reference to the second target transmission power of b′, c′, f′, i′, j′, q′, l′.

[0175] In one embodiment, P LR,PUSCH,b′,f′,c′ (i′, j′, q′ d , l′) represents that LR is using the parameter set configuration with index j′ and the PUSCH power control process with index l′ to send PUSCH on the active uplink (UL) bandwidth part (BWP) b′ of the carrier f′ in serving cell c′. Then LR will determine the second target transmission power of the PUSCH at the PUSCH transmission occasion i′;

[0176] P MR,PUSCH,b,f,c (i, j, q d , l) represents that MR is using the parameter set configuration with index j and the PUSCH power control process with index l to send PUSCH on the active uplink (UL) bandwidth part (Bandwidth Part, BWP) b of the carrier f in serving cell c. Then LR will determine the second target transmission power of the PUSCH at the PUSCH transmission occasion i;

[0177] Corresponding to the PUSCH, the above - mentioned P LR,PUCCH,b′,f′,c′ (i′, q′ u , q′ d , l′) represents the second target transmission power of the PUCCH transmitted by LR, and P MR,PUCCH,b,f,c (i, q u , q d , l) represents the first target transmission power of the PUCCH transmitted by MR; the above - mentioned P LR,SRS,b′,f′,c′ (i′, q′ s , l′) represents the second target transmission power of the SRS transmitted by LR, and P MR,SRS,b,f,c (i, q s , l) represents the first target transmission power of the SRS transmitted by MR; the above - mentioned P LR,PRACH,b′,f′,c′(i′) represents the second target transmission power of the PRACH transmitted by LR, P MR,PRACH,b,f,c (i) represents the first target transmission power of the PRACH transmitted by MR, which will not be elaborated here.

[0178] Embodiment 2: The first information includes the second target transmission power of the second communication module and a third adjustment amount.

[0179] The differences between this embodiment and the above Embodiment 1 include: In this Embodiment 2, the second target transmission power is used as a reference, and based on the third adjustment amount, the second target transmission power is adjusted to obtain the corresponding first target transmission power.

[0180] In the above Embodiment 1 and Embodiment 2, the power control method of using one module among the first communication module and the second communication module as a reference module to control the power of the other module is more suitable for incremental power control in the case where one module activates another module during operation, avoiding the first device from re-obtaining all power control parameters and re-performing path loss estimation, saving signaling overhead and delay in the power control process.

[0181] Embodiment 3: The first information includes the first parameter of the first communication module and a second adjustment amount.

[0182] In this embodiment, the first parameter can be adjusted based on the second adjustment amount to obtain a second parameter. Thereafter, the first device can calculate the first target transmission power based on the first parameter, and calculate the second target transmission power based on the second parameter.

[0183] Among them, the first parameter of the first communication module can refer to the parameters in the power control calculation formula of NR in the related art, which will not be elaborated here.

[0184] Among them, the second parameter of the second communication module can be the parameter in the power control calculation formula for the second signal.

[0185] In some embodiments, the first parameter includes at least one or a combination of at least two of the following parameters corresponding to the first communication module:

[0186] The first target receiving power, the first path loss, the first maximum transmission power, the type of the first signal, the bias value of the first closed-loop power control, the number of RBs of the occupied bandwidth of the first signal, the number of subcarriers included in each RB of the first signal, the number of bits carried by each resource element RE on average in the first signal, the first partial path loss compensation factor;

[0187] Wherein, the first path loss is the path loss between the first device and the third device, and the third device is the receiving-end device of the first signal;

[0188] Or,

[0189] The second parameter includes at least one or a combination of at least two of the following parameters corresponding to the second communication module:

[0190] Second target receiving power, second path loss, second maximum transmission power, type of the second signal, time length of one symbol in the second signal, frequency-domain width of one symbol in the second signal, bias value of the second closed-loop power control, number of RBs of the occupied bandwidth of the second signal, number of subcarriers included in each RB of the second signal, number of bits carried on average by each symbol in the second signal, second partial path loss compensation factor;

[0191] Wherein, the second path loss is the path loss between the first device and the fourth device, and the fourth device is the receiving-end device of the second signal.

[0192] In some embodiments, the above fourth device and third device may be the same device or different devices, which is not specifically limited herein.

[0193] Specifically, the above fourth device may be Figure 9a the base station in Figure 9b the relay node in Figure 9c the amplitude node in Figure 9d the base station in Figure 9e and the UE in Figure 9a the base station in Figure 9b the relay node in Figure 9c the base station in Figure 9d the auxiliary node in Figure 9e and the UE in

[0194] In some embodiments, the method for calculating the second target transmission power according to the second parameter includes the following two types:

[0195] Method 1: Convert the relevant parameters of the second signal into the parameters of an OFDM signal, and substitute the converted parameters into the uplink power calculation formula in the related technology to calculate the second target transmission power of the second signal.

[0196] For example: If the second signal is a single-carrier signal, the parameters of the second signal can be converted into the parameters of an equivalent OFDM signal, and the parameters of the equivalent OFDM signal can be substituted into the power control calculation formula of NR in the related technology to obtain the second target transmission power of the single-carrier signal.

[0197] As an alternative implementation, the second parameter represents the parameters of the OFDM signal equivalent to the second signal. At this time, the second target transmit power can be determined based on the following formula according to the second parameter:

[0198]

[0199] where P' represents the second target transmit power; P' CMAX represents the maximum transmit power of the second communication module; P' O represents the target receive power of the equivalent OFDM signal on 1 RB; represents the number of RBs of the occupied bandwidth B of the second signal; PL' represents the path loss of the second signal; Δ' TF represents the transmit power required by the second communication module for each resource element RE; f' represents the bias value for closed-loop power control of the second signal.

[0200] In some implementations, Δ' TF is determined based on the following formula:

[0201]

[0202] where, γ' represents the number of bits carried on average by each symbol of the second signal; γ′' represents the average number of bits carried by the second signal on each RE; represents the number of OFDM subcarriers included in 1 RB of the second signal; β' 0 and β' 1 are bias values.

[0203] It should be noted that γ' obtains the average number of bits on each single-carrier symbol, while Δ in the OFDM power control calculation formula in the related art TF is defined according to the average number of bits carried by 1 RE. Therefore, γ' also needs to be divided by to obtain the average number of bits carried by the second signal on each RE.

[0204] Optionally, the above second target transmit power may specifically refer to the second target transmit power of the second signal calculated based on the i'-th symbol / transmission time, the j'-th open-loop control configuration, the reference signal q', and the l'-th closed-loop power control process. For simplicity, the above i', j', q', and l' parameters are omitted in the calculation formula of the target transmit power in the embodiments of the present application.

[0205] For example: At the i'-th symbol / transmission time, the j'-th open-loop control configuration, and based on the reference signal q', the second target transmit power on the l'-th closed-loop power control process of the second signal can be calculated based on the following formula:

[0206]

[0207] where P' O (j') is defined in the same way as NR in the related art and is the target received power of the equivalent OFDM signal assumed on an RB with a 15 kHz SCS.

[0208] The above β' 0 and β' 1 are two bias values related to the transmission channel (data / signaling), modulation method, etc., which can be constants or functions of j' and l'. Here, l' is the power control process index; j' is the open-loop control configuration index; β' 0 and β' 1 are optional parameters. In the embodiments of the present application, an optional parameter means that the power adjustment does not change with this parameter (for example: when the values of β' 0 and β' 1 are 1, it is equivalent to not taking effect).

[0209] f'(i', l') is the bias value introduced by the closed-loop power control process l' at time i', which can be indicated by signaling with an absolute value or by the network side with a differential value, and the UE obtains the absolute value through cumulative summation. Optionally, if the closed-loop power control has not taken effect, such as when the TPC signaling has not been received or before the connection is established, f'(i', l')f(i, l) may not exist, and only open-loop power control is available at this time.

[0210] Optionally, the above target transmit power can also be defined for BWP b', carrier f' and cell c'. For simplicity, the parameters b', f', c' are also omitted in the formula for calculating the target transmit power in the embodiments of the present application.

[0211] In this embodiment, by converting the parameters of the second signal into the parameters of the equivalent OFDM signal, the second target transmit power of the second communication module for the second signal can be calculated based on the power control calculation formula for NR in the related art.

[0212] Method 2: Design an uplink power calculation formula for the second signal and substitute the second parameter corresponding to the second signal into this formula to calculate the second target transmit power of the second signal.

[0213] As an alternative embodiment, the second signal is a single-carrier signal, and the second parameter represents a parameter in the power control calculation formula defined for the second signal. At this time, the second parameter can be substituted into the following formula to obtain the second target transmit power:

[0214] P' = min{P' CMAX , P' O,S + PL' + Δ' TF,S + f'};

[0215] Wherein, P' O,S represents the target receive power on one single-carrier symbol; Δ' TF,S represents the transmit power required by the second communication module for each single-carrier symbol.

[0216] In some embodiments, since the single-carrier signals that may be modulated at each moment are different, therefore, P' O,S can take the average power of the second signal, or take the total power accumulated over a fixed bandwidth from the power spectral density of the second signal as P' O,S .

[0217] For example: Assume the second signal is an OOK / ASK signal. If there are two modulation symbols, 0 and 1, which appear with equal probability, then the average power is 0.5.

[0218] For another example: Calculate according to the calculated / measured power spectral density (PSD) of the random signal. For example, according to a certain criterion, the total power accumulated over a selected region within a certain bandwidth can be used as P O,S , such as only selecting the region within the first main lobe for power accumulation.

[0219] In some embodiments, Δ' TF,S is determined based on the following formula:

[0220]

[0221] Wherein, T' s represents the time length of a single-carrier symbol in the second signal; B' represents the frequency-domain width of a single-carrier symbol in the second signal; β' 2 and β' 3 are two offset values.

[0222] Optionally, the above-mentioned second target transmission power may specifically refer to the second target transmission power of the second signal calculated based on the i'-th symbol / transmission time, the j'-th open-loop control configuration, the reference signal q', and the l'-th closed-loop power control process. For simplicity, the i', j', q', and l' parameters are omitted in the formula for calculating the target transmission power in the embodiments of the present application.

[0223] For example, the second target transmission power of the second signal at the i'-th symbol / transmission time, the j'-th open-loop control configuration, based on the reference signal q', and the l'-th closed-loop power control process can be calculated based on the following formula:

[0224] P'(i', j', q', l') = min{P' CMAX (i'), P' O,S (i') + PL'(q') + Δ' TF,S + f'(i', l')}

[0225] Wherein, P' O,S (i') is defined as the second target reception power on one single-carrier symbol, which is independent of the bandwidth but related to the modulation mode. For example, it is defined as the average power under a certain modulation mode, the 3dB bandwidth power of the average power spectral density, etc.;

[0226] Generally, T s B = 1, but in high spectral efficiency communications, it may be set that T s B < 1;

[0227] β' 2 and β' 3 are two bias values related to the transmission channel (data / signaling) of the second signal, the modulation mode, etc., which can be constants or functions of j' and l', and are defined by the network side or the protocol. β' 2 and β' 3 are optional parameters. In the embodiments of the present application, the fact that a certain parameter is optional means that the power adjustment does not change with this parameter (for example: when the values of β' 2 and β' 3 are 1, it is equivalent to not taking effect).

[0228] In this embodiment, when the second signal is a single-carrier signal, based on the characteristics of the single-carrier signal, a formula for calculating the uplink transmission power applicable to the single-carrier signal is defined. In this way, the second parameters of the single-carrier signal can be directly substituted into the above formula to calculate the second target transmission power of the second communication module for the single-carrier signal.

[0229] Embodiment 4: The first information includes the second parameters of the second communication module and the fourth adjustment amount.

[0230] The differences between this embodiment and the above Embodiment 3 include: In this Embodiment 4, taking the second parameter as a reference, the second parameter is adjusted based on the fourth adjustment amount to obtain the first parameter.

[0231] The above Embodiment 3 and Embodiment 4 can perform joint power control on the first communication module and the second communication module, so as to configure the power control parameters of the two communication modules through one power parameter configuration process. For example: If it is necessary to turn on two communication modules simultaneously when the first device is powered on, the power control parameters of the two communication modules can be obtained based on the above Embodiment 3 and Embodiment 4 at this time.

[0232] Embodiment 5: The first information can directly indicate the first parameter and the second parameter.

[0233] In this embodiment, the first device can directly obtain the first parameter and the second parameter, and respectively calculate the first target transmit power and the second target transmit power based on the first parameter and the second parameter.

[0234] In some embodiments, the method further includes:

[0235] The first device obtains first association information;

[0236] When the first information includes the first target transmit power and the first adjustment amount, the first association information is used to indicate the association relationship between the first target transmit power, the first adjustment amount, and the second target transmit power;

[0237] When the first information includes the first parameter and the second adjustment amount, the first association information is used to indicate the association relationship between the first parameter, the second adjustment amount, and the second parameter;

[0238] When the first information includes the second target transmit power and the third adjustment amount, the first association information is used to indicate the association relationship between the second target transmit power, the third adjustment amount, and the first target transmit power;

[0239] When the first information includes the second parameter and the fourth adjustment amount, the first association information is used to indicate the association relationship between the second parameter, the fourth adjustment amount, and the first target transmit power.

[0240] In some embodiments, the first association information may be the b, f, c, i, j, q, l of the first signal and the association information of the b′, f′, c′, i’, j’, q’, l’ of the second signal.

[0241] Optionally, if b, f, c, i, j, q, l have the same values as the associated b′, f′, c′, i′, j′, q′, l′, it indicates that the two are associated with each other.

[0242] Alternatively, the association relationship between b, f, c, i, j, q, l and b′, f′, c′, i′, j′, q′, l′ can be indicated by means of network - side indication or protocol agreement.

[0243] For the first embodiment described above, the first association information is used to indicate the association relationship between the first target transmit power, the first adjustment amount, and the second target transmit power. In this way, the first target transmit power can be adjusted using the first adjustment amount to obtain the second target transmit power associated with the first adjustment amount and the first target transmit power.

[0244] For the second embodiment described above, the first association information is used to indicate the association relationship between the first parameter, the second adjustment amount, and the second parameter. In this way, the first parameter can be adjusted using the second adjustment amount to obtain the second parameter associated with the second adjustment amount and the first parameter.

[0245] For the third embodiment described above, the first association information is used to indicate the association relationship between the second target transmit power, the third adjustment amount, and the first target transmit power. In this way, the second target transmit power can be adjusted using the third adjustment amount to obtain the first target transmit power associated with the third adjustment amount and the second target transmit power.

[0246] For the fourth embodiment described above, the first association information is used to indicate the association relationship between the second parameter, the fourth adjustment amount, and the first target transmit power. In this way, the second parameter can be adjusted using the fourth adjustment amount to obtain the first parameter associated with the fourth adjustment amount and the second parameter.

[0247] In some embodiments, the second adjustment amount includes at least one of the following:

[0248] Adjustment amount of the target received power: ΔP MR->LR,O,b′,f′,c′ ;

[0249] Adjustment amount of the partial path loss compensation factor: Δα MR->LR,b′,f′,c′ ;

[0250] Adjustment amount of the path loss: ΔPL MR->LR,b′,f′,c′ ;

[0251] Adjustment amount of the power control bias value: Δf MR->LR,b′,f′,c′ ;

[0252] Other adjustment amount: For example, when the LR only supports the uplink (UpLink only, UL only), the power control of the LR can refer to the reference signal received power (RSRP) of the MR downlink to measure the path loss. However, the downlink path loss cannot be directly used as the UL path loss because the MR and LR may use different frequency points and different signal formats, and an additional path loss offset value needs to be added to compensate for these factors.

[0253] It should be noted that the above second adjustment amount can be associated with parameters such as i, j, q, l, for example, ΔP MR->LR,O,b′,f′,c′ (i′, j′, q′, l′).

[0254] As an optional implementation manner, the method further includes:

[0255] The first device measures the reference signal from the fourth device by using the first communication module to obtain a third path loss;

[0256] The first device determines a path loss offset value according to the difference between the reference signal and the second signal;

[0257] The first device determines the second path loss according to the third path loss and the path loss offset value.

[0258] Among them, the third path loss may be the path loss between the first device and the fourth device measured based on the reference signal corresponding to the first communication module. The second path loss is the path loss caused by transmitting the second signal between the first device and the fourth device.

[0259] It should be noted that the signals transmitted by the first communication module and the second communication module may be signals of different transmission formats or different bandwidths. Therefore, it is necessary to determine the path loss offset value between the path losses measured based on these two signals according to the difference between the reference signal measured by the first communication module and the second signal, and adjust the third path loss measured by the first communication module for the reference signal between the first device and the fourth device based on this path loss offset value to obtain the second path loss between the second communication module and the fourth device.

[0260] It is worth noting that the above path loss offset value can be independently indicated without passing through the second adjustment amount, but can be included in the second path loss or the offset value of the second closed-loop power control.

[0261] In this implementation manner, the path loss measurement function of the first communication module can be used to determine the second path loss between the second communication module and the fourth device.

[0262] It should be noted that in some embodiments, when the second communication module has a reference signal measurement function, the path loss measurement function of the second communication module can also be used to measure the second path loss between the second communication module and the fourth device.

[0263] In some embodiments, when the signal transmission bandwidths of the first communication module and the second communication module are different:

[0264] The second adjustment amount includes a first power adjustment amount, and the first power adjustment amount is used to indicate the power adjustment caused by the conversion of the signal transmission bandwidth of the first communication module to the signal transmission bandwidth of the second communication module; or,

[0265] The fourth adjustment amount includes a second power adjustment amount, and the second power adjustment amount is used to indicate the power adjustment caused by the conversion of the signal transmission bandwidth of the second communication module to the signal transmission bandwidth of the first communication module.

[0266] Wherein, the above first power adjustment amount and second power adjustment amount are used to indicate the power adjustment caused by different signal transmission bandwidths.

[0267] For example: when the first signal is an orthogonal frequency division multiplexing (OFDM) signal, the second signal is a single-carrier signal, and the second target transmission power of the second signal is calculated using the signal transmission bandwidth definition of OFDM:

[0268] The first power adjustment amount is:

[0269] The second power adjustment amount is:

[0270] Wherein, The number of resource blocks (RBs) of the occupied bandwidth B of the second signal; The number of resource blocks (RBs) of the occupied bandwidth B of the first signal.

[0271] In some embodiments, the second signal uses the bandwidth definition of OFDM to calculate the second target transmission power, which may be to convert the parameters of the second signal into the second parameters of an equivalent OFDM signal, and calculate the second target transmission power by substituting the second parameters into the following formula:

[0272] Or,

[0273]

[0274] Taking the calculation of the second target transmission power based on the following formula as an example:

[0275]

[0276] In the second embodiment above, for the parameter item corresponding to the signal bandwidth in MR Since the signal bandwidth of LR is RB (SCS is 2 μ′ ×15 kHz), then the first power adjustment amount to be added is That is Equal to

[0277] In the fourth embodiment above, assume the parameter item corresponding to the signal bandwidth in LR Since the signal bandwidth of LR is RB (SCS is 2 μ′ ×15 kHz), if the signal bandwidth of MR is (for 2 μ ×15 kHz), then the second power adjustment amount to be added is That is Equal to

[0278] In some embodiments, when the first signal is an orthogonal frequency division multiplexing OFDM signal, the second signal is a single - carrier signal, and the second signal uses the bandwidth definition of a single - carrier to calculate the second target transmission power:

[0279] The first power adjustment amount is:

[0280] The second power adjustment amount is:

[0281] Wherein, represents the number of RBs of the occupied bandwidth B of the first signal.

[0282] In some embodiments, that the second signal uses the bandwidth definition of a single - carrier to calculate the second target transmission power may be substituting a second parameter into the following formula defined for a single - carrier signal to calculate the second target transmission power:

[0283] P' = min{P' CMAX , P' O,S + PL'+ Δ' TF,S + f'}; or

[0284] P'(i', j', q', l') = min{P' CMAX (i'), P' O,S (i') + PL'(q') + Δ' TF,S + f'(i', l')};

[0285] Taking the calculation of the second target transmission power based on the following formula as an example:

[0286] P'(i', j', q', l') = min{P' CMAX (i'), P' O,S (i') + PL'(q') + Δ' TF,S + f'(i', l')};

[0287] In the second embodiment above, for the parameter item corresponding to the signal bandwidth in MR Since there is no parameter item corresponding to the signal bandwidth in the power control calculation formula of LR, therefore, the first power adjustment amount to be added is

[0288] In the fourth embodiment above, since there is no parameter item corresponding to the signal bandwidth in the power control calculation formula of LR, if the signal bandwidth of MR is (being 2 μ × 15 kHz), then the second power adjustment amount to be added is

[0289] In some embodiments, when the signal transmission formats of the first communication module and the second communication module are different:

[0290] The second adjustment amount includes a third power adjustment amount, and the third power adjustment amount is used to indicate the power adjustment caused by the conversion of the signal transmission format of the first communication module to the signal transmission format of the second communication module; or,

[0291] The fourth adjustment amount includes a fourth power adjustment amount, and the fourth power adjustment amount is used to indicate the power adjustment caused by the conversion of the signal transmission format of the second communication module to the signal transmission format of the first communication module.

[0292] Among them, the above third power adjustment amount and fourth power adjustment amount are used to indicate the power adjustment caused by different signal transmission formats.

[0293] For example: The third power adjustment amount includes: Δ LR,TF -Δ MR,TF ;

[0294] The fourth power adjustment amount includes: Δ MR,TF -Δ LR,TF ;

[0295] Among them, Δ MR,TF represents the transmission power required by the first communication module for each resource element RE; Δ LR,TFIndicates the transmission power required for each RE of the second communication module;

[0296] When the first signal is an orthogonal frequency division multiplexing (OFDM) signal, the second signal is a single - carrier signal, and the second target transmission power is calculated using the bandwidth definition of OFDM:

[0297] When the first signal is an orthogonal frequency division multiplexing (OFDM) signal, the second signal is a single - carrier signal, and the second target transmission power is calculated using the bandwidth definition of single - carrier:

[0298] Where γ' represents the number of bits carried on average by each symbol in the second signal; Indicates the number of OFDM sub - carriers included in one RB; Indicates the number of RBs, β', of the occupied bandwidth B of the second signal; 0 and β' 1 Are two bias values; T s Indicates the time length of a single - carrier symbol; B represents the frequency - domain width of a single - carrier symbol; β' 2 and β' 3 Are two bias values.

[0299] In some embodiments, at least one of the above - mentioned first power adjustment amount, second power adjustment amount, third power adjustment amount, and fourth power adjustment amount can be indicated by the network side or agreed upon by the protocol.

[0300] In other embodiments, at least one of the above - mentioned first power adjustment amount, second power adjustment amount, third power adjustment amount, and fourth power adjustment amount can be determined by the first device according to the difference between the first signal sent by the first communication module and the second signal sent by the second communication module.

[0301] It should be noted that when the adjustment amount (such as at least one of the first adjustment amount, second adjustment amount, third adjustment amount, and fourth adjustment amount) in the above - mentioned first information is configured by the network side (such as the second device), the configuration method of this adjustment amount can include at least one of the following:

[0302] Configuration method 1: Directly configure the adjustment amount. Among them, BWP, carrier, serving cell, i (occasion), j (parameter set configuration index), q (associated reference signal), and l (power control adjustment state index) can be adjusted. For example: Using the first target receiving power of MR's BWP 1 as a reference, adjust the second target receiving power value of LR's BWP 2. Then directly indicate that the first adjustment amount regarding P MR,O,1,f,c is ΔP MR->LR,O,2 , then the second target receiving power value of LR on any f and c can be obtained as P LR,O,2,f,c = P MR,O,1,f,c + ΔP MR->LR,O,2 .

[0303] Configuration method 2: Pre-define or configure at least two sets of possible adjustment amount correspondence relationships, and the network side indicates to activate one set of adjustment values.

[0304] For example: Configure at least two sets of possible adjustment amounts based on Table 1 below:

[0305] Table 1

[0306]

[0307] As shown in Table 1 above, each set of adjustment amounts is uniquely indicated by its respective index (0, 1). Thereafter, the network side can indicate this index so that the first device uses the set of adjustment amounts corresponding to this index.

[0308] Configuration method 3: Configure the static power control parameters in the first parameter and the second parameter respectively, and indicate the dynamic power control parameters in the first parameter and the second parameter through TPC signaling.

[0309] In some embodiments, when the first information includes the first parameter and the second parameter, the first device obtaining the first information includes:

[0310] The first device obtains the first configuration information;

[0311] The first device receives the transmission power control TPC signaling;

[0312] Among them, the first configuration information is used to configure the first static power control parameter and the second static power control parameter; the TPC signaling indicates the first dynamic power control parameter and the second dynamic power control parameter;

[0313] The first parameter includes the first static power control parameter and the first dynamic power control parameter; the second parameter includes the second static power control parameter and the second dynamic power control parameter.

[0314] In some embodiments, the above first configuration information represents static power control parameters, such as: target received power, reference signal, partial path loss compensation factor, etc.

[0315] Optionally, the target static power control parameter includes at least one of the following:

[0316] Target received power;

[0317] Partial path loss compensation factor;

[0318] A parameter set composed of the target received power and the partial path loss compensation factor;

[0319] Reference signal for estimating path loss;

[0320] Maximum number of retransmissions;

[0321] Step size of power ramping;

[0322] Wherein, the target static power control parameter includes at least one of the first static power control parameter and the second static power control parameter.

[0323] In some embodiments, when the first communication module and the second communication module have the same type of channel / signal, the first configuration information may be the configuration information of the power control parameter of the OFDM communication module in the related art. For example: add fields to the configuration information of the power control parameter of the OFDM communication module to indicate the first static power control parameter through the existing fields and indicate the second static power control parameter through the added fields.

[0324] For example: for at least one of the channels or signals such as PRACH, PUSCH, SRS, PUCCH, the network side can indicate at least one of the following parameter groups to the first device through the first configuration information:

[0325] 1) The target received power p0-MR of MR, the target received power p0-LR of LR;

[0326] Optionally, the first configuration information can indicate the bias value of the target received power of MR compared to a given threshold, and the bias value of the target received power of LR compared to a given threshold. For example, the target received power of Msg3 PUSCH can be the bias value compared to the target received power of PRACH.

[0327] 2) The partial path loss compensation factor alpha-MR of MR and the partial path loss compensation factor alpha-LR of LR;

[0328] 3) The parameter set composed of the target receiving power of MR and LR and the partial path loss compensation factor;

[0329] 4) The reference signal for MR to estimate the first path loss and the reference signal for LR to estimate the second path loss;

[0330] 5) The maximum number of retransmissions of MR and the maximum number of retransmissions of LR;

[0331] 6) The step size of power ramping of MR and the step size of power ramping of LR.

[0332] It should be noted that each of the above parameter groups may include an absolute value and a relative value. For example, the absolute value directly indicates the parameter value of MR, while the parameter value of LR is indicated in the form of an offset value (Offset). Then, the actual parameter value adopted by LR is the sum / difference / product / quotient of the MR parameter value and the Offset.

[0333] In some embodiments, when at least one of the channels / signals of the first communication module and the second communication module is inconsistent, the first configuration information may indicate at least one first static power control parameter of a channel / signal of MR and at least one second static power control parameter of a channel / signal of LR.

[0334] It should be noted that in this embodiment, although the power control parameters of MR and LR are configured separately and their signal / channel types are different, the parameters of one channel / signal of MR or LR can still be used as the reference parameters of a certain channel / signal of the other module. Then, the first configuration information only needs to indicate the static power control parameters of the reference channel / signal and the offset value of the static power control parameters of the other module relative to the reference channel / signal.

[0335] In some embodiments, the above TPC signaling is used to indicate dynamic power control parameters, such as power control offset values.

[0336] Optionally, the TPC signaling may be the TPC field in DCI.

[0337] In this embodiment, the power of PUSCH, SRS or PUCCH can be dynamically adjusted through the TPC signaling. And according to different usage scenarios, the TPC signaling can indicate an absolute power offset value or a relative power offset value. The latter needs to accumulate all the relative power offset values to perform power control.

[0338] Optionally, the target dynamic power control parameters include at least one of the following:

[0339] A first power offset value and a first scaling factor, and a second power offset value is determined based on the first power offset value and the first scaling factor;

[0340] A second power offset value and a second scaling factor, and a first power offset value is determined based on the second power offset value and the second scaling factor;

[0341] A first identifier that associates the first power offset value and the second power offset value;

[0342] The first power offset value and the second power offset value;

[0343] A target power offset value and first indication information, where the first indication information is used to indicate that the target power offset value is the power offset value of the first communication module or the second communication module;

[0344] Wherein, the target dynamic power control parameter includes at least one of the first dynamic power control parameter and the second dynamic power control parameter; the first power offset value is the offset value of the first target transmit power; the second power offset value is the offset value of the second target transmit power.

[0345] In some embodiments, in order to use the TPC signaling to adjust the power of two modules, at least one of the following methods can be adopted to redesign and interpret the TPC field:

[0346] Method 1: The network side indicates which one of the first communication module and the second communication module the power offset value carried in the TPC field is applied to. The first device interprets the scaling factor s from the TPC field and performs at least one of operations such as summation / difference / product / quotient on the power offset value in the TPC field and the scaling factor s to obtain the power offset value of the other communication module among the first communication module and the second communication module.

[0347] Optionally, the power offset value carried in the above TPC field may indicate an absolute power offset value or a relative power offset value, which is not specifically limited herein.

[0348] Method 2: The network side can associate the first identifier with the first power offset value and the second power offset value in advance through network side configuration or protocol agreement, and carry the first identifier through the TPC field. In this way, the first device can obtain two-dimensional information based on the one-dimensional TPC field based on the new interpretation method, that is, interpret the first power offset value and the second power offset value.

[0349] For example: The network side configures the association information between the first identifier and the first power offset value and the second power offset value through Table 2 below:

[0350] Table 2

[0351]

[0352] As shown in Table 2 above, the TPC field carries a first identifier (i.e., 0 or 1), and the first device determines the LR absolute power offset value and the MR absolute power offset value indicated by the network side, or the LR relative power offset value and the MR relative power offset value, or the LR absolute power offset value and the MR relative power offset value, or the LR relative power offset value and the MR absolute power offset value according to the first identifier carried by the TPC field.

[0353] Method 3: Designing the TPC field means being able to indicate two TPC values, which are the TPC values of the first communication module and the second communication module respectively.

[0354] Optionally, the TPC includes two fields, namely {TPC 1, TPC 2}, where TPC 1 acts on MR or LR, and TPC2 acts on the other module.

[0355] Optionally, the interpretation tables of the above TPC 1 and TPC 2 can be the same or different, and no specific limitation is made here.

[0356] Optionally, what TPC 2 indicates can be the offset value relative to TPC 1.

[0357] Method 4: The TPC field can act on only one or both of MR and LR, and can indicate the communication module on which the TPC field acts in an explicit or implicit manner.

[0358] An implicit indication method is: assuming that the DCI where the TPC is located is the DCI that only schedules one of MR and LR, then the TPC value only acts on this module.

[0359] An explicit indication method is: another field different from the TPC field in the DCI indicates the module on which the TPC value acts. For example, this other field is: TPC_module, TPC_module = 00 means it acts on LR, TPC_module = 01 means it acts on MR, and TPC_module = 10 means it acts on LR and MR.

[0360] In this embodiment, the target dynamic power control parameter can be interpreted from the TPC field through the design or interpretation method of the TPC field.

[0361] It should be noted that in the existing NR protocol, the maximum transmission power is determined by the Radio Resource Control (RRC) parameter P-Max, but NR has only one communication module. In the embodiments of the present application, the first device has two communication modules. At this time, it is necessary to limit the maximum transmission power of the two communication modules.

[0362] As an alternative implementation, the first target transmission power and the second target transmission power satisfy at least one of the following conditions:

[0363] First condition: The first target transmission power is less than or equal to the first maximum transmission power, and the second target transmission power is less than or equal to the second maximum transmission power;

[0364] Second condition: The sum of the first target transmission power and the second target transmission power is less than or equal to the target maximum transmission power, and the target maximum transmission power is the maximum total transmission power of the first communication module and the second communication module.

[0365] In some embodiments, independent maximum transmission powers can be set for the MR and the LR. At this time, the target transmission power of the MR and the target transmission power of the LR need to be less than or equal to their respective corresponding maximum transmission powers.

[0366] Optionally, the network side can indicate a maximum transmission power P-Max and a scaling value P-Scale. At this time, P-Max can be used as the maximum transmission power of one of the MR and the LR, and the maximum transmission power of the other of the MR and the LR can be obtained by performing an operation (such as at least one of addition / subtraction / multiplication / division) on P-Scale and P-Max.

[0367] In some other embodiments, a maximum transmission power can be set for the first device. At this time, the sum of the target transmission powers of the MR and the LR is less than or equal to the maximum transmission power of the first device.

[0368] In some embodiments, when the first target transmission power and the second target transmission power do not satisfy the second condition, the method further includes:

[0369] The first device obtains second indication information, and the second indication information is used to indicate the transmission power allocation method of the first communication module and the second communication module;

[0370] The first device updates the first target transmission power and the second target transmission power according to the second indication information and the target maximum transmission power, wherein the updated first target transmission power and second target transmission power satisfy the second condition.

[0371] In this embodiment, a method for indicating the transmission power allocation of the LR and the MR through the second indication information is used to prevent the sum of the target transmission powers of the LR and the MR from exceeding the maximum transmission power of the first device.

[0372] Optionally, the second indication information is used to indicate any one of the following:

[0373] The proportions of the first target transmission power and the second target transmission power in the total transmission power of the first device respectively; or,

[0374] When the sum of the target transmission powers of the first communication module and the second communication module is greater than the target maximum transmission power, the target transmission power of the first communication module or the second communication module is preferentially reduced so that the sum of the first target transmission power and the second target transmission power is less than or equal to the target maximum transmission power.

[0375] In this embodiment, the second indication information can be used to constrain the target transmission power of at least one of the MR and the LR in any of the following ways:

[0376] 1) Define the power proportion of at least one of the MR and the LR. In this way, the proportion of the transmission power of at least one of the MR and the LR in the maximum transmission power of the first device can be determined according to the power proportion. For example: limit the maximum transmission power of the LR to be less than or equal to 20% of the maximum transmission power of the first device, and the remaining 80% of the maximum transmission power of the first device is the maximum transmission power of the MR.

[0377] 2) When the sum of the target transmission powers of the MR and the LR calculated based on the power control calculation formula is greater than the maximum transmission power of the first device, the second indication information can be used to indicate how to reduce the transmission power of the first device. For example: scale the target transmission powers of the MR and the LR so that the sum of the target transmission powers of the MR and the LR is less than or equal to the target maximum transmission power, or, the transmission power of the MR or the LR can be preferentially guaranteed to remain unchanged, and only the transmission power of the other communication module is reduced so that the total transmission power of the first device is less than or equal to the target maximum transmission power.

[0378] Optionally, the relevant parameters of the maximum transmission power of at least one of the above MR and LR (such as the maximum transmission power of the MR, the maximum transmission power of the LR, the scaling value P-Scale, the maximum transmission power P-Max, the second indication information, etc.) can be indicated based on RRC or other signaling.

[0379] In the embodiments of the present application, for a first device that simultaneously has a main communication module (i.e., the first communication module) and a very low power consumption communication module (i.e., the second communication module), power control can be performed on the two communication modules on the first device based on the first information, so that the first target transmission power of the first signal transmitted based on the main communication module on the first device and the second target transmission power of the second signal transmitted based on the very low power consumption communication module on the first device are more flexible, improving the communication performance of the first device.

[0380] Refer to Figure 12 , the embodiments of the present application also provide another transmission power control method, and the execution subject of this another transmission power control method is a second device. As Figure 12 shown, the another transmission power control method executed by this second device includes the following steps:

[0381] Step 121, the second device sends the first information to the first device. The first device includes a first communication module and a second communication module, and the second communication module is a very low power consumption communication module; the first information is used to determine the first target transmission power of the first signal by the first communication module and the second target transmission power of the second signal by the second communication module.

[0382] In some embodiments, the second device may be a device for configuring or indicating the first information to the first device. For example: a network-side device. This network-side device may be an access network device or a core network device. Among them, in the case where the fourth device includes a core network device, demand information such as the target reception power can be obtained by using an application server in the core network, or the target transmission power can be calculated by using the computing function in the core network.

[0383] It should be noted that the above first information, first device, first parameter, first communication module, second communication module, first signal, first target transmission power, second signal, and second target transmission power have the same meaning and function as the first information, first device, first parameter, first communication module, second communication module, first signal, first target transmission power, second signal, and second target transmission power in the method embodiments on the first device side, and will not be elaborated here.

[0384] The embodiments of the present application correspond to the method embodiments on the first device side. Among them, the method embodiments on the first device side are used to determine the target transmission power of the two communication modules on the first device, and the method embodiments on the second device side can control the transmission power of the two communication modules on the first device based on the first information.

[0385] In some embodiments, the first information includes at least one of the following:

[0386] The first target transmission power and the first adjustment amount of the first communication module, and the second target transmission power is determined based on the first target transmission power and the first adjustment amount;

[0387] The first parameter and the second adjustment amount of the first communication module, and the second parameter is determined based on the first parameter and the second adjustment amount;

[0388] The second target transmission power and the third adjustment amount of the second communication module, and the first target transmission power is determined based on the second target transmission power and the third adjustment amount;

[0389] The second parameter and the fourth adjustment amount of the second communication module, and the first parameter is determined based on the second parameter and the fourth adjustment amount;

[0390] The first parameter and the second parameter;

[0391] Wherein, the first parameter includes a parameter for determining the first target transmission power; the second parameter includes a parameter for determining the second target transmission power.
