[0041] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0042] 1. Frequency Domain Spectral Shaping (FDSS) Technology

[0043] After a discrete time-domain signal passes through a digital-to-analog converter (DAC) module, the peak-to-average ratio of the analog signal output has a certain relationship with the correlation between the discrete time-domain data. Assume that a discrete time-domain data signal y(n) is time-convolved with a discrete time-domain data signal d(n), obtaining yd(n):

[0044] Assume that the peak-to-average power ratios (PAPR1) and PAPR2 of the output signals of y(n) and yd(n) after passing through the DAC are respectively. If d(n) is a set of designed weight coefficients, the correlation between adjacent data points of yd(n) will be better than that of adjacent data points of y(n). The higher the correlation, the lower the peak-to-average power ratio (PAPR), so PAPR2 will be smaller than PAPR1. Convolving a set of discrete time-domain data with a set of designed discrete data can effectively reduce the PAPR.

[0045] According to the convolution theorem, the convolution of two time-domain signals is equivalent to a dot product of the two signals in the frequency domain. Therefore, transforming a set of discrete time-domain data into discrete frequency-domain data after performing the DFT, then performing the dot product with a designed spectrum shaping sequence, and then performing the IDFT on the resulting time-domain signal can effectively reduce PAPR. Because the dot product operation is less complex than the convolution operation, this PAPR reduction technique works better in the frequency domain, hence the name frequency-domain spectrum shaping.

[0046] 2. Regional Division of MPR Resource Block Allocation

[0047] Taking power class 3 as an example, the following parameters are defined to specify the effective range of three different resource block (RB) area divisions in the MPR indicator: outer, inner, and edge: RB start,low =max(1,floor(L CRB / 2)); RB start,high =N RB –RB Start,Low –L CRB ;

[0048] Among them, L CRB Indicates the number of consecutive RB allocations in RB units; N RB Indicates the maximum number of RBs under the transmission channel bandwidth configuration and subcarrier spacing configuration adopted by the terminal; max() represents the maximum value of all parameters, and floor(x) is the largest integer less than or equal to x.

[0049] 1) If the RB allocation meets the following conditions, the allocation belongs to inner RB allocation or inner region: start,low ≤RBstart≤RBstart,high, and L CRB ≤ceil(NRB / 2);

[0050] Among them, RB start is the RB starting position or the lowest RB index of RB allocation; ceil(x) is the smallest integer greater than or equal to x.

[0051] 2) If an RB allocation satisfies the following conditions, the RB allocation belongs to edge RB allocation or edge region:

[0052] L CRB ≤2, and the RB is located at the top or bottom of the channel.

[0053] 3) Other types of RB allocation belong to outer RB allocation or outer area.

[0054] Specifically, the MPR under power category 3 may be as shown in Table 1.

[0055] Table 1 MPR of power category 3

[0056] Note that Table 1 above applies to UEs operating in Time Division Duplex (TDD) mode. When the UE uses Pi / 2BPSK modulation and supports powerboost-pi2bpsk, with powerBoostPi2BPSK set to 1, bands n40, n41, n77, n78, and n79 use less than 40% of the time slots in the radio frame for uplink (UL) transmission. The reference power for 0dB MPR is 26dBm.

[0057] It should also be noted that for the above Table 1, it applies to UEs operating in Frequency Division Duplexing (FDD) mode, or using frequency bands other than n40, n41, n77, n78 and n79 in TDD mode, with Pi / 2BPSK modulation, and IE powerBoostPi2BPSK is set to 0, and more than 40% of the time slots in the radio frame are used for UL transmission in the n40, n41, n77, n78 and n79 frequency bands.

[0058] 3. Maximum Output Power Boosting Mechanism of Related Technologies

[0059] P EMAX,c The maximum output power value of the terminal allowed by the network side is P PowerClass is the maximum output power of the UE specified for the corresponding power level, ΔP PowerClass It is the change value of the maximum output power corresponding to a certain power level under certain conditions, usually 0dB, 3dB or 6dB. c is the maximum power reduction value. ΔMPR c is the maximum power reduction allowed. c The maximum power fallback value is used to meet the additional requirements. P-MPRc is the power fallback value used to meet the electromagnetic radiation requirements using the distance sensor. ΔTC,c is the power relaxation value allowed at the edge of the operating band. ΔT IB,c The maximum configured output power is relaxed due to the support of operations such as inter-band carrier aggregation (CA). RxSRS It is the relaxation value allowed for the Sounding Reference Signal (SRS) antenna switch to transmit on a non-primary transmit (Tx) antenna.

[0060] Specifically, the maximum output power P on the terminal side CMAX,f,c Satisfies the following formula, P CMAX_H,f,c and P CMAX_L,f,c P CMAX,f,c The upper and lower limits of P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c ; P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass )–MAX(MAX(MPR c +ΔMPR c , A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS ,P-MPR c )}; P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass};

[0061] When the terminal supports the pi / 2 binary phase shift keying power boosting (powerBoosting-pi2BPSK) capability and the information element (IE) powerBoostPi2BPSK is set to 1, for terminals using power level 3 of PI / 2BPSK modulation in TDD bands n40, n41, n77, n78, and n79, P EMAX,c Increase 3dB, ΔP PowerClass =-3dB. At this time, the upper limit P CMAX_H,f,c and the lower limit P CMAX_L,f,c are raised accordingly, the maximum output power P CMAX,f,c It also rose accordingly.

[0062] At the same time, the reference power of 0dB MPR also increases with ΔP PowerClass The MPR value of different resource block allocation areas also increases accordingly.

[0063] The output power control method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0064] Please refer to FIG2 , which is a flowchart of an output power control method provided in an embodiment of the present application. The method can be executed by a terminal, as shown in FIG2 , and includes the following steps:

[0065] Step 201: The terminal increases the upper limit of the maximum output power of the terminal according to the target power adjustment value;

[0066] The lower limit value of the maximum output power of the terminal remains unchanged, or the target power adjustment value is related to the RB allocation of the terminal.

[0067] In this embodiment, the target power adjustment value may also be referred to as a target power boosting value, which may be expressed as ΔP PowerBoost Exemplarily, the target power adjustment value may be determined by the terminal according to the RB allocation of the terminal, or may be indicated by a network side device. For example, the network side device may determine the target power adjustment value according to the RB allocation of the terminal and indicate it to the terminal.

[0068] The RB allocation of the terminal (ie, RB allocation) is used to indicate the RB resources allocated by the network side device to the terminal.

[0069] The upper limit of the maximum output power of the terminal (i.e. P CMAX_H,f,c ), where the maximum output power on the terminal side (i.e. P CMAX,f,c) needs to be less than or equal to the upper limit of the maximum output power.

[0070] In one embodiment, the terminal increases the upper limit of the maximum output power of the terminal according to the target power adjustment value, and keeps the lower limit of the maximum output power of the terminal unchanged, that is, the terminal only increases the upper limit of the maximum output power of the terminal according to the target power adjustment value. This can reduce the increase in power level caused by the increase in maximum output power, not only simplifying the implementation method of the maximum output power increase, but also reducing the restriction on the output power of the terminal, thereby improving the freedom of terminal implementation.

[0071] It should be noted that, in this embodiment, the target power adjustment value may be a value agreed upon by a protocol, a value indicated by a network-side device, or a value determined according to RB allocation of the terminal, etc., and this embodiment does not limit this.

[0072] In another embodiment, the terminal increases the upper limit of the maximum output power of the terminal according to the target power adjustment value, and the target power adjustment value is related to the RB allocation of the terminal. For example, the above-mentioned target power adjustment value is a power adjustment value determined according to the RB allocation of the terminal. Different RB allocations can correspond to different power adjustment values. This is conducive to increasing the upper limit of the maximum output power of the terminal to different degrees for different RB allocations, thereby improving the flexibility of increasing the maximum output power.

[0073] It should be noted that in this embodiment, the terminal can increase the lower limit of the maximum output power of the terminal according to the target power adjustment value, or can keep the lower limit of the maximum output power of the terminal unchanged, which is not limited in this embodiment.

[0074] In another embodiment, the terminal increases the upper limit of the maximum output power of the terminal according to the target power adjustment value, and keeps the lower limit of the maximum output power of the terminal unchanged, and the target power adjustment value is related to the RB allocation of the terminal. This not only simplifies the implementation method of the maximum output power increase, reduces the restriction on the output power of the terminal, and improves the freedom of terminal implementation, but also helps to increase the upper limit of the maximum output power of the terminal to different degrees for different RB allocations, thereby improving the flexibility of the maximum output power increase.

[0075] Optionally, before the terminal increases the upper limit of the maximum output power of the terminal according to the target power adjustment value, the method further includes:

[0076] The terminal reports capability information of the terminal to the network side device, where the capability information is used to indicate that the terminal has power boost capability;

[0077] The terminal receives instruction information from the network side device, where the instruction information is used to instruct the terminal to increase the maximum output power of the terminal.

[0078] Exemplarily, when the terminal has power boosting (powerBoosting) capability, the terminal reports the capability information of the terminal to the network side device to indicate that the terminal has power boosting capability. For example, the above-mentioned power boosting capability may be the power boosting (powerBoosting-r18) capability under the eighteenth version. When the network side device receives the capability information of the terminal reported by the terminal, it may send an indication information to the terminal when it determines that a specific condition is met (for example, the modulation mode of the terminal is a specific modulation mode, the modulation waveform of the terminal is a specific waveform, or the RB allocation of the terminal is a specific type of RB allocation, etc.), and the indication information is used to instruct the terminal to increase the maximum output power of the terminal, or the indication information is used to instruct the terminal to increase the upper limit value of the maximum output power of the terminal. The above-mentioned indication information may also be referred to as power boost indication (powerBoostIndication). When the terminal receives the indication information, it may increase the upper limit value of the maximum output power of the terminal according to the target power adjustment value.

[0079] The above-mentioned indication information may only include an indication for instructing the terminal to increase the upper limit value of the maximum output power of the terminal, or the above-mentioned indication information may include an indication for instructing the terminal to increase the upper limit value of the maximum output power of the terminal and the above-mentioned target power adjustment value.

[0080] Optionally, the method further includes:

[0081] The terminal determines the target power adjustment value according to RB allocation of the terminal.

[0082] Exemplarily, the target power adjustment value can be calculated based on relevant parameters of the terminal's RB allocation (for example, the lowest RB index, the length of continuous resource blocks in units of RB, etc.); alternatively, a correspondence between different types of RB allocations and power adjustment values ​​can be established in advance, and the terminal determines the type of RB allocation of the terminal, and then uses the power adjustment value corresponding to the type of RB allocation of the terminal as the target power adjustment value.

[0083] In this embodiment, the target power adjustment value is determined by the terminal according to the RB allocation of the terminal, which is not only conducive to increasing the upper limit of the maximum output power of the terminal to different degrees for different RB allocations, thereby improving the flexibility of the maximum output power increase, but also conducive to improving the degree of freedom of the terminal in achieving the maximum output power increase.

[0084] Optionally, the target power adjustment value is a power adjustment value corresponding to the RB allocation of the terminal, wherein different types of RB allocations correspond to different power adjustment values.

[0085] In this embodiment, different power adjustment values ​​are set for different types of RB allocations, so that the type of RB allocation of the terminal can be determined, and the power adjustment value corresponding to the type of RB allocation is used as the power adjustment value corresponding to the RB allocation of the terminal.

[0086] It is understandable that this embodiment sets different power adjustment values ​​based on the granularity of RB allocation type, which is conducive to increasing the upper limit of the maximum output power of the terminal to different degrees for different types of RB allocation, thereby improving the flexibility of increasing the maximum output power.

[0087] It should be noted that the type of RB allocation in the embodiment of the present application may also be referred to as a region of RB allocation.

[0088] Optionally, the terminal increasing an upper limit of a maximum output power of the terminal according to the target power adjustment value includes:

[0089] When the first condition is met and the RB allocation of the terminal is a specific type of RB allocation, the terminal increases the upper limit of the maximum output power of the terminal according to the target power adjustment value;

[0090] The first condition includes at least one of the following: the modulation waveform of the terminal is a specific waveform, and the modulation mode of the terminal is a specific modulation mode.

[0091] Optionally, the specific waveform includes one of the following: Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM), Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM);

[0092] Alternatively, the specific modulation mode includes one of the following: Quadrature Phase-Shift Keying (QPSK) and Quadrature Amplitude Modulation (QAM).

[0093] Exemplarily, the above-mentioned specific type of RB allocation may be an RB allocation whose corresponding power adjustment value is greater than 0.

[0094] The following is an example to illustrate this embodiment:

[0095] When the modulation waveform and modulation mode of the terminal are DFT-s-OFDM QPSK, and the terminal has the powerBoosting-r18 capability, the terminal reports the powerBoosting-r18 capability to the network side device. When the network side device receives the powerBoosting-r18 capability reported by the terminal, it allocates RBs to the terminal and determines the type of RB allocation of the terminal. When the power adjustment value corresponding to the type of RB allocation of the terminal is equal to 0 (i.e., ΔP PowerBoost =0), the network side device does not issue an instruction for instructing to increase the maximum output power of the terminal. In this case, the upper limit of the maximum output power of the terminal remains unchanged, for example, it can be maintained at P CMAX_H,f,c =MIN{P EMAX,c ,P PowerClass –ΔP PowerClass}; The power adjustment value corresponding to the RB allocation type of the terminal is greater than 0 (ie, ΔP PowerBoost >0), the network side device sends a powerBoostIndication instruction to the terminal to instruct the terminal to increase the maximum output power of the terminal. In this case, the terminal can increase the upper limit of the maximum output power of the terminal according to the target power adjustment value.

[0096] In this embodiment, when the first condition is met and the RB allocation of the terminal is a specific type of RB allocation, the terminal increases the upper limit of the maximum output power of the terminal according to the target power adjustment value, which can reduce some unnecessary increases in the upper limit of the maximum output power.

[0097] Optionally, the specific type of RB allocation is an RB allocation whose corresponding power adjustment value is greater than 0.

[0098] Exemplarily, when the power adjustment value corresponding to the RB allocation of the terminal is greater than 0, the terminal may increase the upper limit of the maximum output power of the terminal according to the power adjustment value corresponding to the RB allocation of the terminal (ie, the target power adjustment value).

[0099] Optionally, the method further includes:

[0100] The terminal determines, based on a lowest RB index of the RB allocation of the terminal and a resource block length of the RB allocation of the terminal, whether the RB allocation of the terminal is an RB allocation of a specific type;

[0101] The resource block length is the length of the allocated continuous resource blocks in units of RB.

[0102] In this embodiment, the terminal can determine the type of RB allocation of the terminal based on the lowest RB index of the RB allocation of the terminal and the resource block length of the RB allocation of the terminal, and further can determine whether the RB allocation is a specific type of RB allocation based on the type of RB allocation of the terminal. It should be noted that the lowest RB index of the RB allocation of the terminal can be expressed as RB start , the above resource block length can be expressed as L CRB。 In addition, the length of the continuous resource blocks allocated in units of RBs may also be referred to as the number of continuous resource blocks allocated in units of RBs.

[0103] Optionally, when the RB allocation of the terminal satisfies the second condition, the RB allocation of the terminal is a first type of RB allocation;

[0104] The specific type of RB allocation includes the first type of RB allocation;

[0105] The second condition includes: CRB ≤a1 and b1≤RB start ≤c1;a1≤N RB , 0≤b1≤c1≤N RB -L CRB ;

[0106] L CRB Indicates the resource block length, RB start Represents the lowest RB index, N RB Indicates the maximum number of RBs under the transmission channel bandwidth configuration and subcarrier spacing configuration adopted by the terminal.

[0107] In this embodiment, the above a1 can be less than or equal to N RB Any value of b1 and c1 is greater than or equal to 0 and less than or equal to N RB -L CRB Any value of .

[0108] In practical applications, the above a1, b1 and c1 can be reasonably set according to actual needs. In some optional embodiments, at least one of the above a1, b1 and c1 can be a value agreed upon in the protocol.

[0109] It can be understood that since the above-mentioned specific type of RB allocation includes the first type of RB allocation, when the RB allocation of the terminal is the first type of RB allocation, it means that the RB allocation of the terminal is a specific type of RB allocation. In this case, the terminal can increase the upper limit value of the maximum output power of the terminal according to the target power adjustment value; otherwise, the terminal may not increase the upper limit value of the maximum output power of the terminal.

[0110] Optionally, the power adjustment value corresponding to the first type of RB allocation is a first power adjustment value, and the first power adjustment value is greater than 0;

[0111] Wherein, when the RB allocation of the terminal is the first type of RB allocation, the target power adjustment value is the first power adjustment value.

[0112] Exemplarily, the first power adjustment value may be agreed upon by a protocol.

[0113] In some optional embodiments, when the RB allocation of the terminal does not satisfy the second condition, or the RB allocation of the terminal is not the first type of RB allocation, the RB allocation of the terminal is the tenth type of RB allocation, and the power adjustment value corresponding to the tenth type of RB allocation is 0.

[0114] The present embodiment is described below with reference to examples:

[0115] In this embodiment, RB can be allocated based on RB start and L CRB RB allocation is divided into the following two types or regions. Specifically, if the RB allocation meets the following conditions, the RB allocation belongs to type 1 (i.e. the first type mentioned above) or region 1 (Region 1), and the ΔP corresponding to this type or region is PowerBoost The size is x1(x1>0)dB, that is, the maximum output power limit can be increased by x1dB:

[0116] L CRB ≤a1 and b1≤RB start ≤c1;a1≤N RB , 0≤b1≤c1≤N RB -L CRB ;

[0117] If the RB allocation does not meet the above conditions or does not belong to type 1 or region 1, then the RB allocation belongs to type 2 (i.e. the tenth type mentioned above) or region 2 (Region 2), and the ΔP corresponding to this type or region is PowerBoost The value is 0dB, that is, the upper limit of the maximum output power remains unchanged, which can be shown in Table 2 for example.

[0118] Table 2

[0119] Optionally, when the RB allocation of the terminal satisfies the third condition, the RB allocation of the terminal is the second type of RB allocation;

[0120] When the RB allocation of the terminal satisfies the fourth condition, the RB allocation of the terminal is the third type of RB allocation;

[0121] The specific type of RB allocation includes the second type of RB allocation and the third type of RB allocation;

[0122] The third condition includes: a2≤L CRB ≤b2 and c2≤RB start ≤d2;a2≤b2≤N RB , 0≤c2≤d2≤N RB -L CRB ;

[0123] The fourth condition includes: a3≤L CRB ≤b3 and c3≤RB start ≤d3;a3≤b3≤N RB , 0≤c3≤d3≤N RB -L CRB ;

[0124] L CRB Indicates the resource block length, RB start Represents the lowest RB index, N RB Indicates the maximum number of RBs under the transmission channel bandwidth configuration and subcarrier spacing configuration adopted by the terminal.

[0125] In this embodiment, the above a2, b2, a3 and b3 can be less than or equal to N RB The above c2, d2, c3 and d3 can be greater than or equal to 0 and less than or equal to N RB -L CRB It is understood that at least one pair of a2 and a3, b2 and b3, c2 and c3, and d2 and d3 is different. For example, a2 and a3 are different, or b2 and b3 are different, or c2 and c3 are different, or d2 and d3 are different.

[0126] In practical applications, the above a2, a3, b2, b3, c2, c3, d2 and d3 can be reasonably set according to actual needs. In some optional embodiments, at least one of the above a2, a3, b2, b3, c2, c3, d2 and d3 can be a value agreed upon in the protocol.

[0127] It can be understood that since the above-mentioned specific type of RB allocation includes the second type of RB allocation and the third type of RB allocation, when the RB allocation of the terminal is any one of the second type of RB allocation and the third type of RB allocation, it means that the RB allocation of the terminal is a specific type of RB allocation. In this case, the terminal can increase the upper limit value of the maximum output power of the terminal according to the target power adjustment value; otherwise, the terminal may not increase the upper limit value of the maximum output power of the terminal.

[0128] Optionally, the power adjustment value corresponding to the second type of RB allocation is a second power adjustment value, and the power adjustment value corresponding to the third type of RB allocation is a third power adjustment value;

[0129] The second power adjustment value and the third power adjustment value are both greater than 0. When the RB allocation of the terminal is the second type of RB allocation, the target power adjustment value is the second power adjustment value. When the RB allocation of the terminal is the third type of RB allocation, the target power adjustment value is the third power adjustment value.

[0130] In this embodiment, the second power adjustment value and the third power adjustment value are different. Exemplarily, the second power adjustment value and the third power adjustment value can both be agreed upon by a protocol.

[0131] In actual applications, when it is determined that the RB allocation of the terminal is the second type of RB allocation, the terminal can increase the upper limit of the maximum output power of the terminal according to the second power adjustment value; when it is determined that the RB allocation of the terminal is the third type of RB allocation, the terminal can increase the upper limit of the maximum output power of the terminal according to the third power adjustment value.

[0132] In some optional embodiments, when the RB allocation of the terminal does not satisfy the third condition and does not satisfy the fourth condition, or the RB allocation of the terminal is neither the second type of RB allocation nor the third type of RB allocation, the RB allocation of the terminal is the eleventh type of RB allocation, and the power adjustment value corresponding to the eleventh type of RB allocation is 0.

[0133] The present embodiment is described below with reference to examples:

[0134] In this embodiment, RBstart and L can be allocated based on RB CRB RB allocation is divided into the following three types or regions. Specifically, if the RB allocation meets the following conditions, the RB allocation belongs to type 3 (i.e. the second type mentioned above) or region 3 (Region 3), and the corresponding ΔP of this type or region is PowerBoost The size is x2(x2>0)dB, that is, the maximum output power limit can be increased by x 2dB:

[0137] a3≤L CRB ≤b3 and c3≤RB start ≤d3;a3≤b3≤N RB , 0≤c3≤d3≤N RB -L CRB ;

[0138] If the RB allocation does not meet the above conditions or does not belong to the above two types or regions, the RB allocation belongs to type 5 (i.e. the eleventh type mentioned above) or region 5 (Region 5), and the ΔP corresponding to this type or region is PowerBoost The value is 0dB, that is, the upper limit of the maximum output power remains unchanged. For example, it can be shown in Table 3.

[0139] Table 3

[0140] Optionally, when the RB allocation of the terminal satisfies the fifth condition, the RB allocation of the terminal is internal RB allocation (ie, inner RB allocation);

[0141] Alternatively, when the RB allocation of the terminal satisfies the sixth condition, the RB allocation of the terminal is edge RB allocation (i.e., edge RB allocation);

[0142] Alternatively, when the RB allocation of the terminal does not satisfy the fifth condition and the sixth condition, or the RB allocation of the terminal is neither inner RB allocation nor edge RB allocation, the RB allocation is outer RB allocation (i.e., outer RB allocation);

[0143] Wherein, the fifth condition includes: L CRB ≤ceil(N RB / 2), and RB start,low ≤RB start ≤RB start,high ;

[0144] The sixth condition includes: L CRB ≤2, and the RB position allocated by the RB allocation is at the uppermost or lowermost end of the channel; RB start,low =max(1,floor(L CRB / 2)), RB start,high =N RB –RB Start,Low –L CRB ;

[0145] L CRB Indicates the resource block length, RB start Represents the lowest RB index, N RB It represents the maximum number of RBs under the transmission channel bandwidth configuration and subcarrier spacing configuration adopted by the terminal, max represents the maximum value function, floor represents the floor function, and ceil represents the ceiling function.

[0146] Optionally, the specific type of RB allocation includes the internal RB allocation;

[0147] The power adjustment value corresponding to the internal RB allocation is a fourth power adjustment value, and the fourth power adjustment value is greater than 0; when the RB allocation of the terminal is the internal RB allocation, the target power adjustment value is the fourth power adjustment value.

[0148] Exemplarily, the fourth power adjustment value may be agreed upon by a protocol.

[0149] It can be understood that since the above-mentioned specific type of RB allocation includes the internal RB allocation, when the RB allocation of the terminal is the internal RB allocation, it means that the RB allocation of the terminal is a specific type of RB allocation. In this case, the terminal can increase the upper limit value of the maximum output power of the terminal according to the fourth power adjustment value; otherwise, the terminal may not increase the upper limit value of the maximum output power of the terminal.

[0150] In some optional embodiments, the power adjustment value corresponding to the edge RB allocation and the power adjustment value corresponding to the external RB allocation may both be 0.

[0151] For example, as shown in Table 4, the corresponding ΔP of the internal RB allocation PowerBoost = x4(x4>0)dB, ΔP corresponding to external RB allocation and edge RB allocation PowerBoost Both are 0.

[0152] Table 4

[0153] Optionally, when the RB allocation of the terminal is the internal RB allocation, if the RB allocation of the terminal meets the seventh condition, the RB allocation of the terminal is the fourth type of RB allocation; wherein, the specific type of RB allocation includes the fourth type of RB allocation, and the seventh condition includes: a4 ≤ L CRB ≤ b4, and c4 ≤ RB start ≤ d4; a4 ≤ b4 ≤ ceil(N RB / 2), RB start,low ≤ c4 ≤ d4 ≤ RB start,high ;

[0154] Or,

[0155] when the RB allocation of the terminal is the edge RB allocation or the external RB allocation, if the RB allocation of the terminal meets the eighth condition, the RB allocation of the terminal is the fifth type of RB allocation; wherein, the specific type of RB allocation includes the fifth type of RB allocation, and the eighth condition includes: e1 ≤ L CRB ≤ f1 and g1 ≤ RB start ≤ h1; ceil(N RB / 2) < e1 ≤ f1 and 0 ≤ g1 ≤ h1 ≤ N RB -L[[ID=2⑤]] CRB , or, e1 ≤ f1 ≤ ceil(N RB / 2) and RB start,high < g1 ≤ h1, or, e1 ≤ f1 ≤ ceil(N RB / 2) and g1 ≤ h1 < RB start,low .

[0156] In this embodiment, both a4 and b4 can be any values less than or equal to ceil(N RB / 2), both c4 and d4 can be any values greater than or equal to RB start,low and less than or equal to RB start,high . Both e1 and f1 can be any values greater than ceil(N RB / 2), and both g1 and h1 can be any values greater than or equal to 0 and less than or equal to N RB -L CRB ; or, both e1 and f1 can be any values less than or equal to ceil(N RB / 2), and both g1 and h1 can be any values greater than RB start,high ; or, both e1 and f1 can be any values less than or equal to ceil(N RB / 2), and both g1 and h1 can be any values less than or equal to RB start,low .

[0157] In practical applications, the above a4, b4, c4, d4, e1, f1, g1 and h1 can be reasonably set according to actual needs. In some optional embodiments, at least one of the above a4, b4, c4, d4, e1, f1, g1 and h1 can be a value agreed upon in the protocol.

[0158] It can be understood that since the above-mentioned specific type of RB allocation includes the fourth type of RB allocation and the fifth type of RB allocation, when the RB allocation of the terminal is any one of the fourth type of RB allocation and the fifth type of RB allocation, it means that the RB allocation of the terminal is a specific type of RB allocation. In this case, the terminal can increase the upper limit value of the maximum output power of the terminal according to the target power adjustment value; otherwise, the terminal may not increase the upper limit value of the maximum output power of the terminal.

[0159] Optionally, the power adjustment value corresponding to the fourth type of RB allocation is a fifth power adjustment value, or the power adjustment value corresponding to the fifth type of RB allocation is a sixth power adjustment value;

[0160] Among them, the fifth power adjustment value and the sixth power adjustment value are both greater than 0. When the RB allocation of the terminal is the fourth type of RB allocation, the target power adjustment value is the fifth power adjustment value. When the RB allocation of the terminal is the fifth type of RB allocation, the target power adjustment value is the sixth power adjustment value.

[0161] In this embodiment, the fifth power adjustment value is different from the sixth power adjustment value. Exemplarily, the fifth power adjustment value and the sixth power adjustment value may be agreed upon by a protocol.

[0162] In actual applications, when it is determined that the RB allocation of the terminal is the fourth type of RB allocation, the terminal can increase the upper limit of the maximum output power of the terminal according to the fifth power adjustment value; when it is determined that the RB allocation of the terminal is the fifth type of RB allocation, the terminal can increase the upper limit of the maximum output power of the terminal according to the sixth power adjustment value.

[0163] In some optional embodiments, when the RB allocation of the terminal is the internal RB allocation, if the RB allocation of the terminal does not satisfy the seventh condition or the RB allocation is not the fourth type of RB allocation, the RB allocation is a twelfth type of RB allocation, and the power adjustment value corresponding to the twelfth type of RB allocation is 0;

[0164] or,

[0165] When the RB allocation is the edge RB allocation or the external RB allocation, if the RB allocation does not meet the eighth condition or the RB allocation is not the fifth type of RB allocation, then the RB allocation is the thirteenth type of RB allocation, and the power adjustment value corresponding to the thirteenth type of RB allocation is 0.

[0166] The following is an example to illustrate this embodiment:

[0167] This embodiment can be based on RBstart and L of the RB allocation CRB First, divide the RB allocation into internal RB allocation, external RB allocation, and edge RB allocation, and further divide the internal RB allocation into two types or two regions, and divide the external RB allocation and edge RB allocation into two types or two regions.

[0168] Specifically, when the RB allocation is an internal RB allocation, if the RB allocation meets the following conditions, then the RB allocation belongs to type 6 or region 6 (Region6), and the corresponding ΔP of this type or region PowerBoost has a size of x5 (x5>0) dB, that is, the maximum output power upper limit can be increased by x5 dB:

[0169] a4 ≤ L CRB ≤ b4, and c4 ≤ RB start ≤ d4; a4 ≤ b4 ≤ ceil(N RB / 2), RB start,low ≤ c4 ≤ d4 ≤ RB start,high ;

[0170] If the RB allocation does not meet the above conditions or does not belong to the above type 6 or region 6, then the RB allocation belongs to type 7 or region 7 (Region7), and the corresponding ΔP of this type or region PowerBoost has a size of 0 dB, that is, the maximum output power upper limit remains unchanged.

[0171] When the RB allocation is an edge RB allocation or an external RB allocation, if the RB allocation meets the following conditions, then the RB allocation belongs to type 8 or region 8 (Region8), and the corresponding ΔP of this type or region PowerBoost has a size of x6 (x6>0) dB, that is, the maximum output power upper limit can be increased by x6 dB:

[0172] e1 ≤ L CRB ≤ f1 and g1 ≤ RB start ≤ h1; ceil(N RB / 2) < e1 ≤ f1 and 0 ≤ g1 ≤ h1 ≤ N RB -L CRB ,or, e1 ≤ f1 ≤ ceil(N RB / 2) and RB start,high <g1 ≤ h1, or, e1 ≤ f1 ≤ ceil(N RB / 2) and g1 ≤ h1 < RB start,low .

[0173] If the RB allocation does not meet the above conditions or does not belong to the above type 8 or region 8, then the RB allocation belongs to type 9 or region 9 (Region9), and the corresponding ΔP PowerBoost has a magnitude of 0 dB, that is, the maximum output power upper limit remains unchanged. Exemplarily, the ΔP corresponding to the RB allocation of each type or region PowerBoost can be as shown in Table 5.

[0174] Table 5

[0175] Optionally, when the RB allocation of the terminal is the internal RB allocation, if the RB allocation of the terminal meets the ninth condition, then the RB allocation is the RB allocation of the sixth type; if the RB allocation of the terminal meets the tenth condition, then the RB allocation is the RB allocation of the seventh type;

[0176] where, the RB allocation of the specific type includes the RB allocation of the sixth type and the RB allocation of the seventh type;

[0177] The ninth condition includes: a5 ≤ L CRB ≤ b5 and c5 ≤ RB start ≤ d5; a5 ≤ b5 ≤ ceil(N RB / 2), and RB start,low ≤ c5 ≤ d5 ≤ RB start,high ;

[0178] The tenth condition includes: a6 ≤ L CRB ≤ b6, and c6 ≤ RB start ≤ d6; a6 ≤ b6 ≤ ceil(N RB / 2), RB start,low ≤ c6 ≤ d6 ≤ RB start,high .

[0179] In this embodiment, the above a5, b5, a6, and b6 can be any values less than or equal to ceil(N RB / 2), and the above c5, d5, c6, and d6 can be greater than or equal to RB start,low and less than or equal to RB start,highIt is understood that at least one pair of a5 and a6, b5 and b6, c5 and c6, and d5 and d6 is different. For example, a5 and a6 are different, or b5 and b6 are different, or c5 and c6 are different, or d5 and d6 are different.

[0180] In practical applications, the above a5, b5, a6, b6, c5, d5, c6 and d6 can be reasonably set according to actual needs. In some optional embodiments, at least one of the above a5, b5, a6, b6, c5, d5, c6 and d6 can be a value agreed upon in the protocol.

[0181] It can be understood that since the above-mentioned specific type of RB allocation includes the sixth type of RB allocation and the seventh type of RB allocation, when the RB allocation of the terminal is any one of the sixth type of RB allocation and the seventh type of RB allocation, it means that the RB allocation of the terminal is a specific type of RB allocation. In this case, the terminal can increase the upper limit value of the maximum output power of the terminal according to the target power adjustment value; otherwise, the terminal may not increase the upper limit value of the maximum output power of the terminal.

[0182] Optionally, the power adjustment value corresponding to the sixth type of RB allocation is a seventh power adjustment value, and the power adjustment value corresponding to the seventh type of RB allocation is an eighth power adjustment value;

[0183] Among them, the seventh power adjustment value and the eighth power adjustment value are both greater than 0. When the RB allocation of the terminal is the sixth type of RB allocation, the target power adjustment value is the seventh power adjustment value. When the RB allocation of the terminal is the seventh type of RB allocation, the target power adjustment value is the eighth power adjustment value.

[0184] In this embodiment, the seventh power adjustment value and the eighth power adjustment value are different. Exemplarily, the seventh power adjustment value and the eighth power adjustment value can both be agreed upon by a protocol.

[0185] In actual applications, when the RB allocation of the terminal is the internal RB allocation, if it is determined that the RB allocation of the terminal is the sixth type of RB allocation, the terminal can increase the upper limit of the maximum output power of the terminal according to the seventh power adjustment value; if it is determined that the RB allocation of the terminal is the seventh type of RB allocation, the terminal can increase the upper limit of the maximum output power of the terminal according to the eighth power adjustment value.

[0186] In some optional embodiments, when the RB allocation of the terminal is the internal RB allocation, if the RB allocation of the terminal does not meet the ninth condition and does not meet the tenth condition, or the RB allocation of the terminal is not the sixth type of RB allocation and not the seventh type of RB allocation, then the RB allocation of the terminal is the fourteenth type of RB allocation, and the power adjustment value corresponding to the fourteenth type of RB allocation is 0.

[0187] Optionally, when the RB allocation of the terminal is the edge RB allocation or the external RB allocation, if the RB allocation of the terminal meets the eleventh condition, then the RB allocation of the terminal is the eighth type of RB allocation; if the RB allocation of the terminal meets the twelfth condition, then the RB allocation of the terminal is the ninth type of RB allocation;

[0188] Among them, the specific type of RB allocation includes the eighth type of RB allocation and the ninth type of RB allocation;

[0189] The eleventh condition includes: e2 ≤ L CRB ≤ f2 and g2 ≤ RB start ≤ h2; ceil(N RB / 2) < e2 ≤ f2 and 0 ≤ g2 ≤ h2 ≤ N RB -L CRB , or, e2 ≤ f2 ≤ ceil(N RB / 2) and RB start,high < g2 ≤ h2, or, e​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Alternatively, the above e2, f2, e3 and f3 can all be less than or equal to ceil(N RB / 2), and g2, h2, g3, and h3 can all be greater than RB start,high Alternatively, the above e2, f2, e3 and f3 can all be less than or equal to ceil(N RB / 2), and g2, h2, g3, and h3 can all be less than or equal to RB start,low Any value of .

[0192] It can be understood that at least one pair among the above e2 and e3, the above f2 and f3, the above g2 and g3, and the above h2 and h3 are different, for example, the above e2 and e3 are different, or the above f2 and f3 are different, or the above g2 and g3 are different, or the above h2 and h3 are different.

[0193] In practical applications, the above e2, e3, f2, f3, g2, g3, h2 and h3 can be reasonably set according to actual needs. In some optional embodiments, at least one of the above e2, e3, f2, f3, g2, g3, h2 and h3 can be a value agreed upon in the protocol.

[0194] It can be understood that since the above-mentioned specific type of RB allocation includes the eighth type of RB allocation and the ninth type of RB allocation, when the RB allocation of the terminal is any one of the eighth type of RB allocation and the ninth type of RB allocation, it means that the RB allocation of the terminal is a specific type of RB allocation. In this case, the terminal can increase the upper limit value of the maximum output power of the terminal according to the target power adjustment value; otherwise, the terminal may not increase the upper limit value of the maximum output power of the terminal.

[0195] Optionally, the power adjustment value corresponding to the eighth type of RB allocation is a ninth power adjustment value, and the power adjustment value corresponding to the ninth type of RB allocation is a tenth power adjustment value;

[0196] Among them, the ninth power adjustment value and the tenth power adjustment value are both greater than 0. When the RB allocation of the terminal is the eighth type of RB allocation, the target power adjustment value is the ninth power adjustment value. When the RB allocation of the terminal is the ninth type of RB allocation, the target power adjustment value is the tenth power adjustment value.

[0197] In this embodiment, the ninth power adjustment value and the tenth power adjustment value are different. Exemplarily, the ninth power adjustment value and the tenth power adjustment value can both be agreed upon by a protocol.

[0198] In actual applications, when the RB allocation of the terminal is the external RB allocation or the edge RB allocation, if it is determined that the RB allocation of the terminal is the eighth type of RB allocation, the terminal can increase the upper limit of the maximum output power of the terminal according to the ninth power adjustment value; if it is determined that the RB allocation of the terminal is the ninth type of RB allocation, the terminal can increase the upper limit of the maximum output power of the terminal according to the tenth power adjustment value.

[0199] In some optional embodiments, when the RB allocation of the terminal is the external RB allocation or the edge RB allocation, if the RB allocation of the terminal does not satisfy the eleventh condition and does not satisfy the twelfth condition, or the RB allocation of the terminal is not the eighth type of RB allocation and is not the ninth type of RB allocation, then the RB allocation of the terminal is the fifteenth type of RB allocation, and the power adjustment value corresponding to the fifteenth type of RB allocation is 0.

[0200] The present embodiment is described below with reference to examples:

[0201] In this embodiment, RBstart and L can be allocated based on RB CRB First, RB allocation is divided into internal RB allocation, external RB allocation, and edge RB allocation. The internal RB allocation is further divided into three types or three areas, and the external RB allocation and edge RB allocation are divided into three types or three areas.

[0202] Specifically, when the RB allocation is internal RB allocation, if the RB allocation satisfies the following conditions, the RB allocation belongs to type 10 or region 10 (Region 10), and the ΔP corresponding to the type or region is PowerBoost The size is x7 (x7>0)dB, that is, the maximum output power limit can be increased by x7dB:

[0203] a5≤L CRB ≤b5 and c5≤RB start ≤d5;a5≤b5≤ceil(N RB / 2), and RB start,low ≤c5≤d5≤RB start,high ;

[0204] If the RB allocation satisfies the following conditions, the RB allocation belongs to type 11 or region 11 (Region 11), and the ΔP corresponding to this type or region is PowerBoost The size is x8 (x8>0) dB, that is, the maximum output power limit can be increased by x8dB:

[0205] a6≤L CRB ≤b6, and c6≤RB start ≤d6;a6≤b6≤ceil(NRB / 2), RB start,low ≤ c6 ≤ d6 ≤ RB start,high ;

[0206] If the RB allocation does not meet the above conditions or does not belong to the above two types or regions, then this RB allocation belongs to type 12 or region 12 (Region12), and the corresponding ΔP for this type or region PowerBoost has a magnitude of 0 dB, that is, the maximum output power upper limit remains unchanged.

[0207] In the case where the RB allocation is a marginal RB allocation or an external RB allocation, if this RB allocation meets the following conditions, then this RB allocation belongs to type 13 or region 13 (Region13), and the corresponding ΔP for this type or region PowerBoost has a magnitude of x9 (x9 > 0) dB, that is, the maximum output power upper limit can be increased by x9 dB:

[0208] e2 ≤ L CRB ≤ f2 and g2 ≤ RB start ≤ h2; ceil(N RB / 2) < e2 ≤ f2 and 0 ≤ g2 ≤ h2 ≤ N RB -L CRB , or, e2 ≤ f2 ≤ ceil(N RB / 2) and RB start,high < g2 ≤ h2, or, e2 ≤ f2 ≤ ceil(N RB / 2) and g2 ≤ h2 < RB<s start,low [[ID=�]];

[0209] If this RB allocation meets the following conditions, then this RB allocation belongs to type 14 or region 14 (Region14), and the corresponding ΔP for this type or region PowerBoost has a magnitude of x 10 (x 10 > 0) dB, that is, the maximum output power upper limit can be increased by x<000024��>dB:

[0210] e3 ≤ L CRB ≤ f3 and g3 ≤ RB start ≤ h3; ceil(N RB / 2) < e3 ≤ f3 and 0 ≤ g3 ≤ h3 ≤ N RB -L CRB , or, e3 ≤ f3 ≤ ceil(N RB / 2) and RB start,high < g3 ≤ h3, or, e3 ≤ f3 ≤ ceil(N RB / 2) and g3 ≤ h3 < RB start,low ;

[0211] If the RB allocation does not meet the above conditions or does not belong to the above two types or regions, the RB allocation belongs to type 15 or region 15 (Region 15), and the corresponding ΔP PowerBoost The value is 0dB, which means that the upper limit of the maximum output power remains unchanged.

[0212] For example, the ΔPPowerBoost corresponding to the RB allocation of each type or area may be as shown in Table 6.

[0213] Table 6

[0214] It should be noted that the above examples are all illustrated using the DFT-s-OFDM QPSK modulation waveform and modulation mode combination as an example, but do not limit the modulation waveforms and modulation modes that can be used in the embodiments of the present application. Exemplarily, the combinations of modulation waveforms and modulation modes that can be used in the embodiments of the present application may include, but are not limited to, at least one of the following: DFT-s-OFDM and QPSK, CP-OFDM and QPSK, and DFT-s-OFDM and 16QAM.

[0215] Optionally, the upper limit value of the maximum output power of the terminal after the increase is as follows: MIN{P EMAX,c , P PowerClass –ΔP PowerClass +ΔP PowerBoost}; MIN{P EMAX,c +ΔP PowerBoost , P PowerClass –ΔP PowerClass +ΔP PowerBoost};

[0216] Among them, P EMAX,c The maximum output power value of the terminal configured by the network side device, P PowerClass is the maximum output power of the terminal at the first power level agreed upon in the protocol, ΔP PowerClass is the adjustment value of the maximum output power of the terminal at the first power level, ΔP PowerBoost is the target power adjustment value, the first power level is the power level used by the terminal, and MIN represents the minimum value function

[0217] In summary, the output power control method provided in the embodiment of the present application can appropriately raise the upper limit of the maximum output power without raising it to another power level when the output power improvement on the terminal side is relatively limited.
