[0080] Figure 2 It is a schematic flowchart of a power determination method provided by the embodiments of the present application. It should be noted that the method is applied to a terminal.

[0081] As Figure 2 shown, the power determination method may include the following steps:

[0082] Step 201: Obtain the first boundary value corresponding to the current power level of the terminal, where the maximum transmission power of the terminal is less than or equal to the first boundary value.

[0083] In the embodiments of the present application, the terminal can obtain a first boundary value corresponding to the current power class, and this first boundary value is the boundary value of the maximum transmission power of the terminal.

[0084] Among them, the maximum transmission power of the terminal is less than or equal to this first boundary value. That is, this first boundary value is the upper boundary value of the maximum transmission power of the terminal.

[0085] In some embodiments, different power classes correspond to different first boundary values.

[0086] In some embodiments, the terminal can also obtain a second boundary value corresponding to the current power class, and this second boundary value is also the boundary value of the maximum transmission power of the terminal.

[0087] Among them, the maximum transmission power of the terminal is greater than or equal to this second boundary value. That is, this second boundary value is the lower boundary value of the maximum transmission power of the terminal.

[0088] In some embodiments, different power classes correspond to different second boundary values.

[0089] In some embodiments, the first boundary value obtained by the terminal can be represented by P CMAX_H,f,c and P CMAX_H,f,c can be calculated using the following formula:

[0090] P CMAX_H,f,c = MIN{P EMAX,c , P PowerClass - ΔP PowerClass}.

[0091] Among them, P EMAX,c is the maximum allowable UE output power notified by the higher layer signaling sent by the serving cell c of the terminal, P PowerClass is the nominal UE power of the current power class, and ΔP PowerClass is the maximum output power adjustment of the current power class.

[0092] In some embodiments, the second boundary value obtained by the terminal can be represented by P CMAX_L,f,c and P CMAX_L,f,c can be calculated using the following formula:

[0093] 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 + ΔTC,c +ΔT RxSRS , P-MPR c )}。

[0094] Wherein, P EMAX,c is the maximum allowable terminal (UE) output power notified by the high-layer signaling sent by serving cell c, ΔT C,c is the relaxation of the transmission power at the edge of the operating frequency band allowed by serving cell c, P PowerClass is the nominal terminal (UE) power of the current power level, ΔP PowerClass is the maximum output power adjustment of the current power level, MPR c is the maximum power back-off allowed by serving cell c, ΔMPR c is the relaxation of the maximum power back-off allowed by serving cell c, A-MPR c is the additional maximum power back-off notified by the high-layer signaling sent by serving cell c, ΔT IB,c is the maximum configured output power relaxation allowed for serving cell c due to supporting inter-band carrier aggregation (CA) operation, inter-band NR dual connection (NR-DC) operation, and due to supporting supplementary uplink (SUL) operation, ΔT RxSRS is related to the sounding reference signal (SRS) and the operating frequency band, P-MPR c is the power management maximum power back-off of serving cell c.

[0095] In some embodiments, the maximum transmission power of the terminal can be represented by P CMAX,f,c as follows.

[0096] Wherein, P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c .

[0097] Step 202, obtain the maximum power back-off MPR corresponding to the terminal.

[0098] In the embodiments of the present application, the terminal can obtain the maximum power back-off MPR corresponding to its own current conditions.

[0099] In some embodiments, the terminal can determine the MPR corresponding to the terminal based on its current power level, modulation method, and resource allocation situation.

[0100] In some embodiments, the terminal can allow the relaxation of the above MPR based on the agreement of the protocol.

[0101] Step 203: Obtain the additional maximum power reduction A-MPR of the terminal.

[0102] In the embodiments of the present application, the terminal can obtain the corresponding additional maximum power reduction A-MPR under the current conditions.

[0103] In some embodiments, the terminal can receive network signaling sent by a network device, and the network signaling is used to indicate the A-MPR of the terminal.

[0104] Step 204: Determine that the first power reduction value is equal to the larger value between the maximum power reduction MPR and the additional maximum power reduction A-MPR.

[0105] In the embodiments of the present application, the terminal can determine the first power reduction value based on the obtained MPR and A-MPR.

[0106] Wherein, the first power reduction value is equal to MAX(MPR, A-MPR).

[0107] In some embodiments, in some embodiments, the terminal can allow the relaxation of the above MPR based on the agreement of the protocol, and the first power reduction value is equal to MAX(MPR + ΔMPR, A-MPR), where ΔMPR is the allowed relaxation of the maximum power reduction.

[0108] In some embodiments, the above power reduction values corresponding to different serving cells may be different.

[0109] Step 205: Determine that the maximum transmission power of the terminal is equal to the difference between the above first boundary value and the above first power reduction value.

[0110] In the embodiments of the present application, the terminal can perform power reduction based on the above first boundary value and the above first power reduction value, and then determine the maximum transmission power of the terminal.

[0111] In some embodiments, when the radio frequency device of the terminal is at the edge of the operating band (band), the actual transmission power of the device cannot reach the maximum transmission power specified by this power level, and additional maximum power reduction A-MPR is required.

[0112] In some embodiments, the terminal determines that the maximum transmission power is equal to the difference between the above first boundary value and the above first power reduction value.

[0113] In some embodiments, determine the maximum transmission power P of the terminal CMAX,f,c =P CMAX_H,f,c -MAX(MPR + ΔMPR, A-MPR).

[0114] In some embodiments, after the terminal determines the maximum transmit power, it may send an uplink signal to the network device based on the maximum transmit power.

[0115] In the embodiments of the present application, by obtaining a first boundary value corresponding to the current power level of the terminal, where the maximum transmit power of the terminal is less than or equal to the first boundary value; obtaining the maximum power reduction (MPR) corresponding to the terminal; receiving network signaling sent by the network device, the network signaling being used to indicate the additional maximum power reduction (A-MPR) of the terminal; determining that the first power reduction value is equal to the larger value of the maximum power reduction (MPR) and the additional maximum power reduction (A-MPR); determining that the maximum transmit power of the terminal is equal to the difference between the first boundary value and the first power reduction value; enabling the terminal to determine the maximum transmit power based on the obtained upper boundary value of the transmit power during the communication process, and then using the maximum transmit power to send the uplink signal, while meeting the power reduction requirements of the radio frequency device, effectively enhancing the performance of the terminal, improving the uplink coverage of the terminal, and ensuring that the uplink signal of the terminal can be correctly received.
