[0199] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0200] Uplink power control is crucial in wireless systems. By controlling uplink power, UEs in a cell can ensure the quality of the data they transmit while minimizing interference to other users in the system, thus extending the UE's battery life.

[0201] The process of UE performing PUCCH power control is shown in the following formula.

[0202]

[0203] Among them, P PUCCH,b,f,c (i,q u ,q d (l) represents the transmission power of the terminal on carrier f within the primary cell c at the i-th transmission time; P CMAX,f,c (i) represents the maximum transmission power at the i-th transmission moment, which is determined by the UE level reported by the user; P O_PUCCH,b,f,c (q u ) represents the target power value, q u Indicates the index of the target power value set; μ represents the carrier spacing configuration; Indicates the number of RBs configured at the i-th transmission time; PL b,f,c (q d ) represents the road loss value, q d Indicates the reference signal RS resource index; Δ F_PUCCH (F) represents the PUCCH format offset value; Δ TF,b,f,c (i) represents the dynamic power adjustment factor at the i-th transmission moment; g b,f,c (i,l) represents the first PUCCH closed-loop power control factor at the i-th transmission time; b represents the index of the bandwidth portion BWP; l represents the index of the PUCCH power control adjustment state.

[0204] For g b，f，c (i, l) is an accumulated value, and the accumulation method is shown in the following formula:

[0205]

[0206] Among them, g b,f,c (i-i0,l) represents the PUCCH closed-loop power control factor at the (i-i0)th transmission time, δ PUCCH,b,f,c This is obtained by receiving information from the Transmission Power Control (TPC) instruction field in the Downlink Control Information (DCI). Specifically, the TPC command field in DCI format is transmitted to δ. PUCCH,b,f,c The mapping relationship is shown in Table 1 below:

[0207] Table 1

[0208] TPC command field delta PUCCH,b,f,c ]] 0 -1 dB 1 0 dB 2 1 dB 3 3 dB

[0209] It is set C i The accumulated value of the TPC command word within, c(C) i ) is the Kth time before the PUCCH transmission time i-i0 PUCCH (i-i0)-1 symbols to the Kth symbol before PUCCH transmission time i PUCCH Between (i) symbols, where i0 is greater than 0, the K symbols before time i-i0 satisfy the condition. PUCCH The (i-i0) symbol positions are earlier than time i by K. PUCCH The smallest integer with (i) sign positions.

[0210] When the UE has reached its maximum power during the i-i0 transmission time, and Then g b,f,c (i,l)=g b,f,c (i-i0,l).

[0211] When the UE has reached its minimum power during the i-i0 transmission time, and Then g b,f,c (i,l)=g b,f,c (i-i0,l).

[0212] If the Radio Resource Control (RRC) layer adjusts the user's target power value P at the current moment... O_PUCCH,b,f,c (q u ), then g b,f,c (i,l)=0,k=0,1,...,i.

[0213] However, since the PUCCH power control is related to the maximum transmission power of the user, the maximum transmission power of the user only depends on the capability of the user (i.e., the UE class reported by the user). But for high frequency, since the transmission power limit is variable when the number of resource blocks (RB) is variable, the maximum transmission power under different numbers of RBs will also change. If the maximum transmission power under the current RB configuration is determined only by the UE class reported by the user, the transmission power on each RB may be higher than the power limit of high frequency for a single RB.

[0214] Since the number of scheduled RBs of the user can be changed by high layer signaling in high frequency, the closed loop power control factor in the above PUCCH power control may change the number of RBs scheduled by the user at this time when accumulated calculation is performed. When the power is calculated, the impact of RB change on the transmission power needs to be considered to avoid the calculated transmission power not meeting the requirements or to avoid power jump.

[0215] Therefore, an embodiment of the present application provides a PUCCH power control method, a terminal, a device and a storage medium, which can determine the maximum transmission power at the target transmission moment according to the first number of RBs configured at the target transmission moment and the terminal UE class, determine the first transmission power at the target transmission moment according to the maximum transmission power at the target transmission moment, and improve the accuracy of PUCCH power control.

[0216] The method and the device are based on the same application concept, and since the principles of the method and the device for solving the problem are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

In some network structures, the network device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be geographically separated.

[0219] The terminal device can be a device providing voice and / or data connectivity to a user, a handheld device having wireless connection capability, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device can also be different, for example, in a 5G system, the terminal device can be called a user equipment (User Equipment, UE).

[0220] Figure 1 Figure 1 is one of the flow diagrams of a PUCCH power control method provided by the embodiments of the present application, which can be applied to a terminal. As shown in the figure, the PUCCH power control method can include the following steps: Figure 1

[0221] Step 101, determining the maximum transmission power at the target transmission time according to the number of first RBs configured at the target transmission time and the UE level.

[0222] Step 102, determining the first transmission power at the target transmission time according to the maximum transmission power at the target transmission time. ​

[0223] Specifically, the UE level can refer to a UE level reported by a user, i.e., a capability of the user, and the first RB number can be a number of sending RBs currently configured by the UE, i.e., a number of RBs configured by the network device through high-layer signaling, so that the maximum sending power is determined in relation to not only the capability of the user but also the number of RBs configured by the high-layer signaling.

[0224] In the formula, since the power of a single physical resource block (PRB) is limited, the high frequency can refer to a number of PRBs being a group of variable consecutive integers configured by high-layer signaling to different UEs, and the maximum value of the PRBs corresponds to the maximum sending power. When the maximum value of the PRBs is not configured by the high-layer signaling, the maximum sending power of the UE does not reach the maximum sending power corresponding to the UE level, and corresponds to the maximum sending power under the PRB, so that the maximum sending power is determined in relation to not only the capability of the user but also the number of RBs configured by the high-layer signaling.

[0225] As can be seen from the above embodiments, in the PUCCH power control, the maximum sending power can be determined according to the first RB number configured at the target transmission moment and the terminal UE level, the maximum sending power at the target transmission moment is determined, and then the first sending power at the target transmission moment is determined according to the maximum sending power at the target transmission moment, so as to improve the accuracy of the PUCCH power control.

[0226] Optionally, the maximum sending power at the target transmission moment is determined according to the first RB number configured at the target transmission moment and the UE level, and the method comprises the following steps.

[0227] A first maximum sending power limit value is determined according to the UE level.

[0228] A second maximum sending power limit value corresponding to the first RB number is obtained.

[0229] The maximum sending power at the target transmission moment is determined according to the first maximum sending power limit value and the second maximum sending power limit value.

[0230] Specifically, the first maximum sending power limit value is determined by the UE level reported by the user, and the second maximum sending power limit value is a maximum sending power limit under the currently configured RB, which is determined by the number of RBs configured by the high-layer signaling.

[0231] As can be seen from the above embodiments, in the determination of the maximum sending power, the first maximum sending power limit value and the second maximum sending power limit value are used for the determination, so as to improve the reliability of the maximum sending power.

[0232] Optionally, the maximum transmission power of the target transmission moment is a minimum value between the first maximum transmission power limit value and the second maximum transmission power limit value.

[0233] Specifically, for the maximum transmission power, the determination manner is as shown in the following formula:

[0234]

[0235] wherein, P, CMAX,f,c (i) represents the maximum transmission power, P CMAX,f,c (i) represents the first maximum transmission power limit value, P CMAX,f,c,RB (i) represents the second maximum transmission power limit value.

[0236] As can be seen from the above embodiments, when determining the maximum transmission power, a minimum value between the first maximum transmission power limit value and the second maximum transmission power limit value can be selected as the maximum transmission power.

[0237] Optionally, the obtaining the second maximum transmission power limit value corresponding to the first RB number comprises:

[0238] Receiving the second maximum transmission power limit value sent by the network device.

[0239] Specifically, the terminal can directly obtain the maximum transmission power limit value from the network device. For example, the network device sends the second maximum transmission power limit value to the terminal through high layer signaling. The high layer signaling can be RRC signaling, medium access control control element (MAC-CE), or other signaling, etc.

[0240] As can be seen from the above embodiments, when obtaining the second maximum transmission power limit value, the second maximum transmission power limit value can be directly obtained from the network device, thereby improving the efficiency of obtaining the second maximum transmission power limit value.

[0241] Optionally, the obtaining the second maximum transmission power limit value corresponding to the first RB number comprises:

[0242] Receiving a third maximum transmission power limit value sent by the network device, the third maximum transmission power limit value being a maximum transmission power limit value of a single PRB;

[0243] According to the third maximum transmission power limit value and the first RB number, the second maximum transmission power limit value is determined.

[0244] Specifically, the terminal can obtain a third maximum transmission power limit value from the network device, and calculate the second maximum transmission power limit value according to the third maximum transmission power limit value. The implementation process is shown in the following formula:

[0245]

[0246] wherein, P CMAX,f,c,1RB represents the third maximum transmission power limit value, P CMAX,f,c,RB (i) represents the second maximum transmission power limit value, represents the number of RBs configured at the i th transmission moment, i.e., the number of first RBs.

[0247] As can be seen from the above embodiment, when obtaining the second maximum transmission power limit value, the maximum transmission power limit value of a single PRB can also be obtained from the network device, and then the second maximum transmission power limit value is calculated, thereby improving the flexibility of obtaining the second maximum transmission power limit value.

[0248] Optionally, the obtaining of the second maximum transmission power limit value corresponding to the number of first RBs comprises:

[0249] receiving a fourth maximum transmission power limit value sent by the network device, the fourth maximum transmission power limit value being a maximum transmission power limit value under a unit bandwidth;

[0250] determining the second maximum transmission power limit value according to the fourth maximum transmission power limit value and the number of first RBs.

[0251] Specifically, after the terminal obtains the fourth maximum transmission power limit value, i.e., the transmission power limit value under a unit bandwidth (1 MHZ), the specific process of determining the second maximum transmission power limit value can comprise:

[0252] (1) calculating the occupied bandwidth size according to the number of first RBs and the sub-carrier spacing (SCS) size. That is:

[0253] occupied bandwidth size = number of first RBs x number of SCS per RB.

[0254] The number of SCS can be notified to the terminal by the network device in advance.

[0255] (2) calculating the second maximum transmission power limit value according to the occupied bandwidth size and the fourth maximum transmission power limit value. That is:

[0256] second maximum transmission power limit value = occupied bandwidth size x fourth maximum transmission power limit value.

[0257] From the above embodiments, when the second maximum transmission power limit value is acquired, the maximum transmission power limit value under the unit bandwidth can also be acquired from the network device, and the second maximum transmission power limit value is calculated, thereby improving the flexibility of acquiring the second maximum transmission power limit value.

[0258] Optionally, the first sending power of the target transmission time is determined according to the maximum sending power of the target transmission time, including:

[0259] According to the first RB number and the second RB number configured at the last transmission time of the target transmission time, the first PUCCH closed loop power control factor of the target transmission time is determined.

[0260] The first sending power of the target transmission time is determined according to the maximum sending power of the target transmission time and the first PUCCH closed loop power control factor.

[0261] Specifically, the first RB number can be the RB number configured at the i-th transmission time (i.e., the target transmission time), and the second RB number can be the RB number configured at the i-i0 transmission time (i.e., the last transmission time of the target transmission time). When determining the first PUCCH closed loop power control factor, the second RB number and the first RB number can be determined, so that the first PUCCH closed loop power control factor can be determined in combination with the RB change state.

[0262] For example, the RB change state can include the following four change states:

[0263] State 1: The second RB number is equal to the first RB number.

[0264] State 2: The second RB number is less than the first RB number.

[0265] State 3: The second RB number is greater than the first RB number.

[0266] State 4: The second RB number is not equal to the first RB number.

[0267] From the above embodiments, the second RB number and the first RB number can be determined, so that the first PUCCH closed loop power control factor can be determined in combination with the RB change state, thereby avoiding the influence of RB change on the sending power and avoiding the occurrence of power jump.

[0268] Optionally, in the case where the second RB number is equal to the first RB number, the first PUCCH closed loop power control factor of the target transmission time is determined, including:

[0269] If the second transmit power of the previous transmission time of the target transmission time has reached the maximum transmit power of the previous transmission time of the target transmission time, and the cumulative transmit power control (TPC) value corresponding to the target transmission time is greater than or equal to 0, then the first PUCCH closed-loop power control factor is determined to be the same as the second PUCCH closed-loop power control factor of the previous transmission time of the target transmission time; or,

[0270] If the second transmit power has reached the minimum transmit power of the previous transmission time before the target transmission time, and the TPC accumulated value is less than or equal to 0, then it is determined that the first PUCCH closed-loop power control factor is the same as the second PUCCH closed-loop power control factor; or,

[0271] If the target power value at the target transmission time is adjusted, then the first PUCCH closed-loop power control factor is determined to be 0.

[0272] Specifically, the first PUCCH closed-loop power control factor is an accumulated value, and the accumulation method is shown in the following formula:

[0273]

[0274] Among them, g b,f,c (i-i0,l) represents the PUCCH closed-loop power control factor at the (i-i0)th transmission time, δ PUCCH,b,f,c This is obtained by receiving information from the TPC instruction field in the DCI. For example, the TPC command field in DCI format is sent to δ. PUCCH,b,f,c δ PUCCH,b,f,c The mapping relationship is shown in Table 2 below:

[0275] Table 2

[0276] TPC command field delta PUCCH,b,f,c ]] 0 -1 dB 1 0 dB 2 1 dB 3 3 dB

[0277] It is set C i The accumulated value of the TPC command word within (i.e., the TPC accumulated value), c(C i ) is the Kth time before the PUCCH transmission time i-i0 PUCCH (i-i0)-1 symbols to the Kth symbol before PUCCH transmission time i PUCCH Between (i) symbols, where i0 is greater than 0, the K symbols before time i-i0 satisfy the condition. PUCCH The (i-i0) symbol positions are earlier than time i by K. PUCCH The smallest integer with (i) sign positions.

[0278] When determining the first PUCCH closed-loop power control factor, the following implementation methods may be included, but are not limited to:

[0279] Manner 1-1: when the UE has reached the maximum power at the i-i0transmission moment, the number of RBs configured by high layer signaling at the transmission moment i and the transmission moment i-i0is unchanged, and then g b,f,c (i, l) = g b,f,c (i-i0, l).

[0280] Manner 1-2: when the UE has reached the minimum power at the i-i0transmission moment, the number of RBs configured by high layer signaling at the transmission moment i and the transmission moment i-i0is unchanged, and then g b,f,c (i, l) = g b,f,c (i-i0, l).

[0281] Manner 1-3: if the target power value P O_PUCCH,b,f,c (q u ) of the UE is adjusted by the RRC layer at the current moment, then g b,f,c (i, l) = 0, k = 0, 1,..., i.

[0282] It should be noted that the target power value can refer to the signal power required to be received by the network device. It is related to the detection performance of the network device, that is, the network device needs to receive a signal reaching this power to meet the detection performance requirement

[0283] As can be seen from the above embodiments, in the case where the second number of RBs is equal to the first number of RBs, the first PUCCH closed loop power control factor can be determined according to the size of the second transmission power at the previous transmission moment or whether the target power value is adjusted, thereby improving the accuracy of determining the first PUCCH closed loop power control factor.

[0284] Optionally, in the case where the second number of RBs is less than the first number of RBs, the determining the first PUCCH closed loop power control factor at the target transmission moment comprises:

[0286] or,

[0287] if the first set condition is satisfied, the first PUCCH closed loop power control factor is determined as the first difference value, the first difference value is a difference value between a second PUCCH closed loop power control factor at a last transmission time of the target transmission time and a second difference value, the second difference value is a difference value between a transmission power calculated according to the second RB number and a transmission power calculated according to the first RB number when the second RB number is less than the first RB number; if the first set condition is not satisfied, the first PUCCH closed loop power control factor is determined as a sum of the second PUCCH closed loop power control factor and a TPC accumulated value corresponding to the target transmission time; wherein the first set condition includes that a second transmission power at the last transmission time of the target transmission time has reached a maximum transmission power at the last transmission time of the target transmission time;

[0288] or,

[0289] if the first set condition is satisfied, the first PUCCH closed loop power control factor is equal to the second PUCCH closed loop power control factor; if the first set condition is not satisfied, the first PUCCH closed loop power control factor is determined as a sum of the second PUCCH closed loop power control factor and the TPC accumulated value; wherein the first set condition includes that a second transmission power at the last transmission time of the target transmission time has reached a maximum transmission power at the last transmission time of the target transmission time;

[0290] or,

[0291] the first PUCCH closed loop power control factor is determined as the first difference value;

[0292] or,

[0293] if the first set condition is satisfied, the first PUCCH closed loop power control factor is determined as the first difference value; if the first set condition is not satisfied, the first PUCCH closed loop power control factor is determined as a sum of the first difference value and the TPC accumulated value; wherein the first set condition includes that a second transmission power at the last transmission time of the target transmission time has reached a maximum transmission power at the last transmission time of the target transmission time.

[0294] Specifically, if the RB number configured by the high layer signaling changes, such as: the second RB number is less than the first RB number, that is, the RB number becomes larger, at this time, the following determination modes can be included but are not limited to:

[0295] Mode 2-1: the accumulated value is zero, that is, the first PUCCH closed loop power control factor is determined as 0. That is, g b,f,c (k, l) = 0, k = 0, 1, …, i.

[0296] Since the second term in formula (5) will become larger if the number of RBs increases, it is not reasonable to superimpose the same accumulated value at this time. At this time, the way 2-1 of restarting accumulation can be used, which is less efficient but can ensure that the power of the UE will not suddenly become too large.

[0297] Way 2-2: The maximum power is reached at the previous transmission time, the power value is ensured to be unchanged, and the current accumulated value is equal to the previous accumulated value minus the power difference (positive number) caused by the increase of the number of RBs. That is:

[0298] If the UE has reached the maximum power P' at the transmission time i-i0 CMAX,f,c (i-i0), and the TPC accumulated value is Then:

[0299]

[0300] The rest of the case is:

[0301]

[0302] Where g b,f,c (i-i0, l) is the second PUCCH closed-loop power control factor; g b,f,c (i, l) is the first difference, is the second difference, represents the number of RBs configured at the i-i0th transmission time (i.e., the second number of RBs); represents the number of RBs configured at the i-th transmission time (i.e., the first number of RBs).

[0303] In the above way 2-2, the first difference and the second difference are used to ensure that the output power value is consistent with the output power value of the previous time, and the granularity of TPC cannot be guaranteed to be accumulated by 1 RB. That is, if the number of RBs changes by 1, the TPC may actually be less than 1 dB, so it still needs to be adjusted based on the number of RBs.

[0304] Way 2-3: The maximum power is reached at the previous transmission time, the accumulation is stopped at the target transmission time, and the accumulated value remains unchanged. That is:

[0305] If the UE has reached the maximum power P' at the transmission time i-i0 CMAX,f,c (i-i0), and Then:

[0306] g b,f,c (i, l) = g b,f,c (i-i0, l)

[0307] The rest of the case is:

[0308]

[0309] Method 2-4: Ensure that the sending power of the target transmission moment is equal to the power of the previous transmission moment, that is, the current accumulated value is equal to the previous accumulated value minus the power difference (positive number) caused by the increase of the number of RBs. That is:

[0310]

[0311] Method 2-5: Ensure that the sending power of the current moment is equal to the power of the previous moment plus the accumulated value this time, that is, the current accumulated value is equal to the previous accumulated value minus the power difference (positive number) caused by the increase of the number of RBs, plus the accumulated value this time. That is:

[0312] If the UE has reached the maximum power P' at the i-i0 transmission moment CMAX,f,c (i-i0), and Then:

[0313]

[0314] In other cases:

[0315]

[0316] As can be seen from the above embodiments, in the case where the second number of RBs is less than the first number of RBs, any of the above methods can be used to determine the first PUCCH closed loop power control factor, which improves the accuracy of determining the first PUCCH closed loop power control factor and avoids power jump.

[0317] Optionally, the method further comprises:

[0318] determining the first PUCCH closed loop power control factor as 0;

[0319] or,

[0320] if the second configured condition is met, the first PUCCH closed loop power control factor is determined as a third difference value, the third difference value is a difference value between a second PUCCH closed loop power control factor of a previous transmission time of the target transmission time and a fourth difference value, the fourth difference value is a difference value between a transmission power calculated according to the second RB number and a transmission power calculated according to the first RB number when the second RB number is greater than the first RB number; if the second configured condition is not met, the first PUCCH closed loop power control factor is determined as a sum of the second PUCCH closed loop power control factor and a TPC accumulated value corresponding to the target transmission time; wherein the second configured condition includes that a second transmission power of the previous transmission time of the target transmission time has reached a minimum transmission power of the previous transmission time of the target transmission time;

[0321] or,

[0322] the first PUCCH closed loop power control factor is determined as the third difference value;

[0323] or,

[0325] Specifically, if the RB number configured by the high layer signaling changes, such as: the second RB number is greater than the first RB number, that is, the RB number becomes smaller, at this time, the following determination methods can be included but are not limited to:

[0326] Method 3-1: the accumulated value is zero, that is, the first PUCCH closed loop power control factor is determined as 0. That is, g b,f,c (k, l) = 0, k = 0, 1, …, i.

[0327] Method 3-2: when the previous transmission time reaches the minimum power value, the power value is ensured to be unchanged, and the current accumulated value is equal to the previous accumulated value minus the power difference value (negative number) caused by the RB number becoming smaller.

[0328] If the UE has reached the minimum power at i-i0transmission time, then:

[0329]

[0330] Otherwise:

[0333] The third difference and the fourth difference in the above manner 3-2 are used to ensure that the output power value is consistent with the previous output power value, and the granularity of the TPC cannot be ensured to be accumulated by 1 RB. Even if the number of RBs changes by 1, the TPC may actually be less than 1 dB, so adjustment based on the number of RBs is still needed.

[0334] Manner 3-3: Ensure that the transmission power at the current moment is equal to the power at the previous moment, that is, the current accumulated value is equal to the previous accumulated value minus the power difference (negative number) caused by the decrease in the number of RBs. That is:

[0335]

[0336] Manner 3-4: Ensure that the transmission power at the current moment is equal to the power at the previous moment plus the accumulated value this time, that is, the current accumulated value is equal to the previous accumulated value minus the power difference (negative number) caused by the decrease in the number of RBs, and then plus the accumulated value this time. That is:

[0337] If the UE has reached the minimum power at the i-i0th transmission moment, then

[0338]

[0339] In other cases, then:

[0340]

[0341] As can be seen from the above embodiments, in the case where the second number of RBs is greater than the first number of RBs, any of the above manners can be used to determine the first PUCCH closed loop power control factor, which improves the accuracy of determining the first PUCCH closed loop power control factor and avoids power jumps.

[0344] or,

[0345] if the third setting condition is satisfied, determining the first PUCCH closed loop power control factor as a fifth difference value, the fifth difference value being a difference value between a second PUCCH closed loop power control factor at a last transmission time of the target transmission time and a sixth difference value, the sixth difference value being a difference value between a transmission power calculated according to the second RB number and a transmission power calculated according to the first RB number if the second RB number and the first RB number are different; if the third setting condition is not satisfied, determining the first PUCCH closed loop power control factor as a sum of the second PUCCH closed loop power control factor and a TPC accumulation value corresponding to the target transmission time; wherein the third setting condition comprises that a second transmission power at the last transmission time of the target transmission time has reached a maximum transmission power or a minimum transmission power at the last transmission time of the target transmission time;

[0352] or,

[0353] determining the first PUCCH closed loop power control factor as a sum of the fifth difference value and the TPC accumulation value.

[0354] Specifically, if the RB number configured by the high layer signaling is changed, i.e., the second RB number and the first RB number are not equal, at this time, the following determination modes can be included but are not limited to:

[0355] Method 4-1: the accumulated value is zero, i.e. the first PUCCH closed loop power control factor is determined as 0. That is, g b,f,c (k, l) = 0, k = 0, 1, …, i.

That is,

[0360] wherein g b,f,c (i-i0, l) is the second PUCCH closed loop power control factor; g b,f,c (i, l) is the fifth difference, is the sixth difference, represents the number of RBs configured at the i-i0 transmission time (i.e. the second number of RBs); represents the number of RBs configured at the i transmission time (i.e. the first number of RBs).

[0361] The fifth difference and the sixth difference are used in the above method 4-2 in order to guarantee that the output power value is consistent with the output power value of the previous time, and the granularity of the TPC cannot be guaranteed to be accumulated by 1 RB, that is, if the number of RBs changes by 1, the TPC may actually be less than 1 dB, so adjustment based on the number of RBs is still needed.

[0362] Method 4-3: the maximum power is reached at the previous time, and the accumulation is stopped at the current time, and the accumulated value remains unchanged. That is,

[0363] If the UE has reached the maximum power at the i-i0 transmission time,

[0364] g b,f,c (i, l) = g b,f,c (i-i0, l);

[0365] Otherwise, then:

[0366]

[0367] Method 4-4: the minimum power is reached at the previous time, and the output power is guaranteed to be unchanged, i.e. the current accumulated value is equal to the previous accumulated value minus the power difference (negative number) caused by the decrease of the number of RBs. That is,

[0368] If the UE has reached the minimum power at the i-i0 transmission moment,

[0369]

[0370] Otherwise:

[0371]

That is:

[0374]

[0375] As can be seen from the above embodiments, in the case where the second number of RBs and the first number of RBs are not equal, any of the above methods can be used to determine the first PUCCH closed loop power control factor, which improves the accuracy of determining the first PUCCH closed loop power control factor and avoids power jump.

[0376] Optionally, the first transmission power at the target transmission moment is determined according to the maximum transmission power at the target transmission moment and the first PUCCH closed loop power control factor, comprising:

[0377] A fifth maximum transmission power limit value is determined according to the first PUCCH closed loop power control factor;

[0378] The first transmission power at the target transmission moment is determined according to the fifth maximum transmission power limit value and the maximum transmission power at the target transmission moment.

[0379] Specifically, after determining the first PUCCH closed loop power control factor at the target transmission moment according to the second number of RBs and the first number of RBs configured at the previous transmission moment of the target transmission moment, a fifth maximum transmission power limit value can be calculated according to the first PUCCH closed loop power control factor, and the calculation process is shown in the following formula

[0380]

[0381] Wherein, P1 represents the fifth maximum transmission power limit value at the i-th transmission moment; P O_PUCCH,b,f,c (q u) represents a target power value, q u represents a target power value set index; μ represents a carrier spacing configuration; represents the number of RBs configured at the i-th transmission moment; PL b,f,c (q d ) represents a path loss value, q d represents a reference signal RS resource index; Δ F_PUCCH (F) represents a PUCCH format offset value; Δ TF,b,f,c (i) represents a dynamic power adjustment factor at the i-th transmission moment; g b,f,c (i, l) represents a first PUCCH closed loop power control factor at the i-th transmission moment; b represents an index of a bandwidth part BWP; and l represents a PUCCH power control adjustment state index.

[0382] As can be seen from the above embodiments, after determining the first PUCCH closed loop power control factor at the target transmission moment according to the second number of RBs and the first number of RBs configured at the last transmission moment of the target transmission moment, the fifth maximum transmission power limit value can be calculated according to the first PUCCH closed loop power control factor, and the first transmission power at the target transmission moment can be determined according to the fifth maximum transmission power limit value and the maximum transmission power at the target transmission moment, thereby improving the accuracy of PUCCH power control.

[0383] Optionally, the determining the first transmission power at the target transmission moment according to the fifth maximum transmission power limit value and the maximum transmission power at the target transmission moment comprises:

[0388] As can be seen from the above examples, the first sending power of the target transmission moment can be calculated by the first formula, and the efficiency of determining the first sending power of the target transmission moment is improved.

[0389] The implementation process of the above PUCCH power control will be specifically described below through five examples:

[0390] Example 1: determining the maximum sending power of UE

[0391] (1) The standard protocol determines the maximum sending power value of different UE levels.

[0392] (2) The terminal reports the UE level, and the base station determines the P CMAX,f,c (i) according to the UE level.

[0393] (3) The base station configures the number of RBs occupied by the PUCCH of the UE through high layer signaling.

[0394] (4) The base station calculates the maximum sending power value of the UE under the current number of RBs according to the transmission power limit value P CMAX,1RB of a single PRB of the UE access frequency band and the number of occupied RBs, that is:

[0395]

[0396] The UE is informed of the P CMAX,f,c,RB (i) through high layer signaling.

[0397] (5) The terminal calculates the maximum sending power of the UE, that is

[0398]

[0399] Example 2: determining the maximum sending power of UE

[0400] (1) The standard protocol determines the maximum sending power value of different UE levels.

[0401] (2) The terminal reports the UE level, and the base station determines the P CMAX,f,c (i) according to the UE level.

[0402] (3) The base station configures the number of RBs occupied by the PUCCH of the UE through high-layer signaling.

[0403] (4) The base station informs the UE of the transmission power limit value P CMAX,1RB of a single PRB in the access frequency band through high-layer signaling.

[0404] (5) The terminal calculates the maximum transmission power value P CMAX,1RB of the UE under the current number of RBs according to P

[0405]

[0406] (6) The terminal calculates the maximum transmission power of the UE according to P

[0407]

[0408] Example Three: Determining the Maximum Transmission Power of the UE

[0409] (1) The standard protocol determines the maximum transmission power value of different UE grades.

[0410] (2) The terminal reports the UE grade, and the base station determines P CMAX,f,c (i) according to the UE grade.

[0415] (7) The terminal calculates the maximum transmission power of the UE according to P

[0416]

[0417] Example Four: Determining the Closed-Loop Power Control Factor (Handling When the Number of RBs Increases and Decreases Respectively)

[0418] (1) The terminal stores the transmission power P PUCCH,b,f,c (i-i0, q u , q d , l) of the previous moment i-i0, and stores the number of RBs at the previous moment i-i0.

[0419] (2) If the number of RBs is unchanged, i.e. then when the UE has reached the maximum power P' at the i-i0 transmission moment, and CMAX,f,c (i-i0), and then g b,f,c (i,1) = g b,f,c (i-i0,1).

[0420] When the UE has reached the minimum power at the i-i0 transmission moment, and then g b,f,c (i,1) = g b,f,c (i-i0,1).

[0421] If the RRC layer adjusts the target power value P O_PUCCH,b,f,c (q u ) of the user at the current moment, then g b,f,c (k,1) = 0, k = 0,1,...,i.

[0422] (3) If the number of RBs is increased, i.e. then one of the following methods can be used to calculate the closed loop power control factor:

[0423] Method one: the accumulated value is set to zero.

[0424] Method two: the maximum power is reached at the previous moment, and the accumulation is stopped at the current moment, and the accumulated value remains unchanged.

[0425] Method three: the transmission power at the current moment is ensured to be equal to the power at the previous moment, i.e. the current accumulated value is equal to the previous accumulated value minus the power difference (positive number) caused by the increase in the number of RBs.

[0426] Method four: the transmission power at the current moment is ensured to be equal to the power at the previous moment plus the accumulated value this time, i.e. the current accumulated value is equal to the previous accumulated value minus the power difference (positive number) caused by the increase in the number of RBs, plus the accumulated value this time.

[0427] (4) If the number of RBs is decreased, i.e. then one of the following methods can be used to calculate the closed loop power control factor:

[0428] Method one: the accumulated value is set to zero.

[0429] Method two: when the minimum power value is reached at the previous moment, the power value is ensured to be unchanged.

[0430] Method three: the transmission power at the current moment is ensured to be equal to the power at the previous moment, i.e. the current accumulated value is equal to the previous accumulated value minus the power difference (negative number) caused by the decrease in the number of RBs.

[0431] Method four: ensure that the sending power at the current time is equal to the power at the previous time plus the accumulated value this time, that is, the current accumulated value is equal to the previous accumulated value minus the power difference (negative number) due to the decrease in the number of RBs, plus the accumulated value this time.

[0432] Example five: determine the closed loop power control factor (the number of RBs is increased and decreased uniformly)

[0433] (1) The terminal stores the sending power P at the previous time i-i0 PUCCH,b,f,c (i-i0,q u ,q d ,l) and the number of RBs at the previous time i-i0

[0434] (2) If the number of RBs does not change, that is, then

[0435] When the UE has reached the maximum power P' at the i-i0 transmission time CMAX,f,c (i-i0), and then g b,f,c (i,l) = g b,f,c (i-i0,l).

[0436] When the UE has reached the minimum power at the i-i0 transmission time, and then g b,f,c (i,l) = g b,f,c (i-i0,l).

[0437] If the RRC layer adjusts the target power value P of the user at the current time O_PUCCH,b,f,c (q u ), then g b,f,c (k,l) = 0, k = 0, 1,..., i.

[0438] (3) If the number of RBs changes, that is, then one of the following methods can be used to calculate the closed loop power control factor:

[0439] Method one: the accumulated value is zero.

[0440] Method two a: the maximum power or the minimum power is reached at the previous time, ensure that the output power does not change, that is, the current accumulated value is equal to the previous accumulated value minus the power difference due to the decrease in the number of RBs.

[0441] Method two b: the maximum power is reached at the previous time, the accumulation is stopped at the current time, and the accumulated value remains unchanged; the minimum power is reached at the previous time, and the output power is ensured to be unchanged, that is, the current accumulated value is equal to the previous accumulated value minus the power difference (negative number) due to the decrease in the number of RBs.

[0442] Method three: ensure that the sending power at the current time is equal to the power at the previous time, that is, the current cumulative value is equal to the previous cumulative value minus the power difference caused by the change of the number of RBs.

[0443] Method four: ensure that the sending power at the current time is equal to the power at the previous time plus the cumulative value this time, that is, the current cumulative value is equal to the previous cumulative value minus the power difference caused by the change of the number of RBs, plus the cumulative value this time.
