[0063] The PHRs involved in the embodiments of this application include, but are not limited to, the following three types:

[0064] 1) Type 1 PHR

[0065] Specifically, it is the difference between the UE's nominal maximum transmit power and the estimated UL-SCH (or PUSCH) transmission power for each active serving unit. This includes the PH of the actual PUSCH transmission and the PH of the reference (virtual) PUSCH transmission. The calculation method is basically similar to that in LTE, using the configured transmit power P. CMAX (or virtual P) CMAX Subtract the open-loop portion, closed-loop portion, and other adjustments. The index used in the virtual pH calculation formula is always the 0th value.

[0066] The nominal maximum transmit power of the UE is the nominal power defined by the UE power level, which can be replaced with the maximum output power of the UE or the maximum transmit power of the UE.

[0067] If the UE determines the type 1 PHR based on the actual PUSCH transmission, then the UE calculates the type 1 PHR according to the following formula:

[0068] If the UE determines the type 1 PHR based on the reference PUSCH transmission, then the UE calculates the type 1 PHR according to the following formula:

[0069] 2) Type 2 PHR

[0070] Specifically, it is the difference between the UE's nominal maximum transmit power and the estimated power of UL-SCH and / or PUCCH transmissions on the SpCell of other MAC entities (such as E-UTRA MAC entities in the cases of EN-DC, NE-DC, and NGEN-DC).

[0071] 3) Type 3 PHR

[0072] Specifically, it is the difference between the nominal maximum transmit power of the UE in each active serving cell and the estimated SRS transmit power, including the PH of the actual SRS transmission and the PH of the reference (virtual) SRS transmission.

[0073] If the UE determines the type 3PHR based on the actual SRS transmission, the UE calculates the type 3PHR according to the following formula: PH type3b,,f,c (i,q s ) = P CMAX,f,c (i)-{P O_SRSb,,f,c (q s )+10log 10 (2 μ ·M SRS,b,f,c (i))+α SRS,b,f,c (q s )·PL b,f,c (q d )+h b,f,c (i)};

[0074] If the UE determines the type 3PHR based on the reference SRS transmission, the UE calculates the type 3PHR according to the following formula:

[0075] All three types of PHRs mentioned above can be transmitted via a Medium Access Control Element (MAC CE), including a single-entity MAC CE (which obtains the type 1 PH value for the uplink carrier related to the PCell and obtains the P of the PCell). CMAX,f,c ), and multi-entity MAC CE (obtaining the type 1 / 2 / 3PH value for the uplink carrier related to PCell and other Cells, and obtaining the relevant P CMAX,f,c ).

[0076] The following description, in conjunction with the accompanying drawings, details the power margin reporting method, power margin calculation method, terminal, and network-side equipment provided in this application through some embodiments and application scenarios.

[0077] Figure 2 shows a flowchart of a power margin reporting method provided in an embodiment of this application. This method 200 can be executed by a terminal. As shown in Figure 2, the method may include the following steps.

[0080] In this embodiment of the application, when the first serving cell is configured to include multiple FPs, the size of each FP can be the same or different, and there is no specific limitation. For example, the first serving cell may be configured to include four FPs with sizes of 3MHz, 10MHz, 5MHz, and 5MHz, respectively.

[0081] In this embodiment of the application, the first serving cell may also be configured to include an FP combination. An FP combination includes at least one FP, and may include one FP or multiple FPs, which can be configured, defined, or determined as needed, and are not specifically limited.

Referring to Figure 3, the first serving cell is configured with six FPs, including FP1 to FP6. FP1 and FP2 correspond to frequency band i, FP3 and FP4 correspond to frequency band j, and FP5 and FP6 correspond to frequency band k. For example, the base station can configure FP1 and FP2 to form FP combination 1, configure FP3 and FP4 to form FP combination 2, and configure FP5 and FP6 to form FP combination 3. Of course, other methods can also be used to configure FP combinations, such as configuring an FP combination to include only one FP, etc., and the specific method is not limited.

[0083] In this embodiment of the application, when the terminal reports a PH for the first serving cell, the PH may include:

[0084] The difference between the nominal maximum transmission power of the terminal corresponding to the first serving cell and the estimated total uplink transmission power; wherein the estimated total uplink transmission power is the estimated total uplink transmission power on all FPs and / or FP groups configured or activated in the first serving cell.

[0085] The estimated total uplink transmission power can be any of the following scenarios:

[0089] 4) All FPs activated in the first serving cell;

[0090] 5) All FPs activated in the first serving cell are combined;

[0091] 6) All FPs activated in the first serving cell and all FPs are combined.

[0092] In this embodiment of the application, when the terminal reports multiple PHs for the first serving cell, each of the multiple PHs may include one of the following:

[0094] 2) The difference between the nominal maximum transmission power of the first terminal and the estimated transmission power of the UL-SCH on the corresponding FP;

[0095] 3) The difference between the nominal maximum transmission power of the first terminal and the estimated transmission power of the UL-SCH and / or Physical Uplink Control Channel (PUCCH) on the special cell SpCell of another Medium Access Control (MAC) entity.

[0096] 4) The difference between the nominal maximum transmission power of the first terminal and the estimated transmission power of the UL-SCH and / or PUCCH on a special cell SpCell of another Radio Access Technology (RAT);

[0097] 5) The difference between the nominal maximum transmission power of the first terminal and the estimated transmission power of the sounding reference signal (SRS) on the corresponding FP;

[0098] 6) The difference between the nominal maximum transmission power of the first terminal and the estimated transmission power of the SRS on the corresponding FP;

[0099] 7) Type 1 PHRs, the specific definitions of which can be found in the relevant NR protocols;

[0100] 8) Type 2 PHRs, the specific definition of which can be found in the relevant NR protocols;

[0101] 9) The specific definition of the third type (Type 3) PHR can be found in the relevant NR protocols.

[0102] In the above-mentioned scenarios, the nominal maximum transmission power of the first terminal can include one of the following:

[0103] 1) The nominal maximum transmission power of the terminal corresponding to the first serving cell;

[0104] 2) The nominal maximum transmission power of the terminal corresponding to a FP; wherein, the FP can be any FP configured or activated in the first serving cell;

[0105] 3) The nominal maximum transmission power of the terminal corresponding to an FP association; wherein, the FP association can be any FP association configured or activated in the first serving cell.

[0106] In this embodiment of the application, the above method may further include one of the following:

[0107] 1) The terminal reports its nominal maximum transmission power to the network-side equipment;

[0108] 2) The terminal reports the nominal maximum transmission power of multiple terminals to the network-side equipment, wherein the number of the nominal maximum transmission power of multiple terminals is less than the number of multiple PHs;

[0109] 3) The terminal reports multiple terminal nominal maximum transmission powers to the network-side equipment, where each terminal nominal maximum transmission power corresponds one-to-one with a number of PHs. In this case, the number of terminal nominal maximum transmission powers is equal to the number of PHs.

[0110] In a scenario where a terminal reports its nominal maximum transmission power to the network-side device, the nominal maximum transmission power of the terminal may include one of the following:

[0111] 1) The nominal maximum transmission power of the terminal corresponding to the first serving cell.

[0112] 2) The terminal's nominal maximum transmission power corresponding to the target carrier of the first serving cell; wherein, the target carrier can be any one or more carriers of the first serving cell, without specific limitation.

[0113] 3) The nominal maximum transmission power of the terminal corresponding to the target FP and / or the FP combination in the first serving cell; wherein, the target FP can be any one or more FPs configured or activated in the first serving cell, and the target FP combination can be any one or more FP combinations configured or activated in the first serving cell, without specific limitation.

[0114] In this scenario, the nominal maximum transmission power of the terminal corresponding to the target FP and / or the FP combination may include: the FP and / or the FP combination configured or activated in the first serving cell each corresponding to the same nominal maximum transmission power; or, the FP and / or the FP combination configured or activated in the first serving cell sharing a nominal maximum transmission power.

[0115] 4) The nominal maximum transmission power of the terminal corresponding to the FP or FP association configured or activated in the first serving cell.

[0116] In scenarios where a terminal reports multiple terminal nominal maximum transmission powers to the network-side device, each of these multiple terminal nominal maximum transmission powers may include one of the following:

[0117] 1) The nominal maximum transmission power of the terminal corresponding to the first serving cell;

[0118] 2) The nominal maximum transmission power of the terminal corresponding to one carrier in the first serving cell;

[0119] 3) The nominal maximum transmission power of the terminal corresponding to a FP in the first serving cell; optionally, in this case, the PH reported by the terminal and the nominal maximum transmission power of the terminal both correspond to that FP;

[0120] 4) The nominal maximum transmission power of the terminal corresponding to a FP association in the first serving cell; optionally, in this case, the PH reported by the terminal and the nominal maximum transmission power of the terminal both correspond to that FP association.

[0121] In this embodiment of the application, in a scenario where the terminal reports multiple pH values ​​to the network-side device for a first serving cell, these multiple pH values ​​can all be absolute values, such as N absolute pH values. Alternatively, the multiple pH values ​​can be N, corresponding to a specified pH value and the remaining N-1 pH values. Specifically, the multiple pH values ​​include the absolute value of the specified pH value and N-1 differences. The N-1 differences include the differences between the absolute values ​​of the N-1 pH values ​​and the absolute value of the specified pH value, where N is a positive integer.

[0122] The specified PH can be the PH corresponding to the FP or FP combination with the largest or smallest index among the reported PHs (or all configured or activated FPs and / or FP combinations in the first serving cell), or the PH corresponding to the main FP or main FP combination, or the PH corresponding to the default FP or default FP combination.

[0123] This method of reporting PH using a combination of absolute and difference values ​​can save the number of bits reported or improve the accuracy of the report.

[0124] In this embodiment of the application, in a scenario where a terminal reports multiple nominal maximum transmission powers to the network-side device, these multiple nominal maximum transmission powers can all be absolute values, such as the absolute values ​​of N nominal maximum transmission powers. Alternatively, the multiple nominal maximum transmission powers can be N, corresponding to a specified nominal maximum transmission power of one terminal and the nominal maximum transmission powers of the remaining N-1 terminals. Specifically, the multiple nominal maximum transmission powers include the absolute value of the specified nominal maximum transmission power of one terminal and N-1 differences. The N-1 differences include the differences between the absolute values ​​of the N-1 terminal nominal maximum transmission powers and the absolute value of the specified nominal maximum transmission power of one terminal, where N is a positive integer.

[0125] The specified terminal nominal maximum transmission power can be the terminal nominal maximum transmission power corresponding to the FP or FP combination with the largest or smallest index among the reported terminal nominal maximum transmission power corresponding to the FP and / or FP combination (or all configured or activated FP and / or FP combination in the first serving cell), or the terminal nominal maximum transmission power corresponding to the main FP or main FP combination, or the terminal nominal maximum transmission power corresponding to the default FP or default FP combination.

[0126] This method of reporting the terminal's nominal maximum transmission power using a combination of absolute and difference values ​​can save on the number of bits reported or improve the accuracy of the reporting.

[0127] Furthermore, it is worth mentioning that in scenarios where a terminal reports multiple Personal Terminals (PHs) and multiple terminal nominal maximum transmission powers to the network-side equipment for a first serving cell, these multiple PHs can correspond one-to-one with the multiple terminal nominal maximum transmission powers, i.e., the number is equal, and / or the order is the same. In one implementation, multiple PHs and multiple terminal nominal maximum transmission powers can all be reported using a combination of absolute values ​​and differences. Optionally, for PHs reported using absolute values, the corresponding terminal nominal maximum transmission power is also reported using absolute values, and the remaining N-1 PHs are ordered in the same way as the remaining N-1 terminal nominal maximum transmission powers. Alternatively, one PH can be reported entirely using absolute values, while the other can be reported using both absolute values ​​and differences; for example, multiple PHs can be reported using absolute values, and multiple terminal nominal maximum transmission powers can be reported using both absolute values ​​and differences, or vice versa.

[0128] In this embodiment of the application, one or more pH values ​​can be reported via MAC CE.

[0129] The size of a MAC CE carrying multiple PHs can be determined by the number of FPs and / or FP combinations configured or activated in the first serving cell.

[0130] In this embodiment of the application, the uplink transmission within the FP and / or FP federation configured or activated in the first serving cell may include at least one of the following: UL-SCH, PUCCH, SRS.

[0131] The method provided in this application embodiment reports one or more power margins to the network-side device via a terminal for a first serving cell. The first serving cell is configured to include at least one power field (FP). For a single cell that aggregates multiple discrete spectrums, it provides a solution for power margin reporting, which can reduce network-side operation and maintenance overhead and improve the flexibility and efficiency of resource utilization.

[0132] Figure 4 shows a flowchart of a power margin reporting method provided in an embodiment of this application. This method 400 can be executed by a terminal. As shown in Figure 4, the method may include the following steps.

[0133] S402: The terminal reports one or more PHs to the network-side equipment for the first serving cell, wherein the first serving cell is configured to include at least one FP.

[0134] In this embodiment, the plurality of pH values ​​can all be absolute values, such as N absolute pH values. Alternatively, the plurality of pH values ​​can be N, corresponding to a specified pH value and the remaining N-1 pH values. Specifically, the plurality of pH values ​​includes the absolute value of the specified pH value and N-1 differences. The N-1 differences include the differences between the absolute values ​​of the N-1 pH values ​​and the absolute value of the specified pH value, where N is a positive integer.

[0135] This method of reporting PH using a combination of absolute and difference values ​​can save the number of bits reported or improve the accuracy of the report.

[0136] In this embodiment of the application, one or more PHs can be reported via a MAC CE. The size of the MAC CE carrying multiple PHs can be determined by the number of FPs configured or activated in the first serving cell and / or the number of FP associations.

[0137] In this embodiment of the application, the uplink transmission within the FP and / or FP federation configured or activated in the first serving cell may include at least one of the following: UL-SCH / PUSCH, PUCCH, SRS.

[0138] S404: The terminal reports one or more terminal nominal maximum transmission power to the network-side equipment.

[0139] The number of terminals with nominal maximum transmission power can be less than or equal to the number of PHs, and there is no specific limitation.

Or, the nominal maximum transmission power P of the multiple terminals. CMAX It can also be M, specifically including one P. CMAX The absolute value and M-1 differences. These M-1 differences include M-1 P values. CMAX The absolute values ​​of P are respectively related to the P CMAX The difference in absolute values. M is the number of terminal nominal maximum transmission powers reported by the terminal, M≤N, where N is the number of multiple PHs reported by the terminal, and both M and N are positive integers.

[0141] This method of reporting the terminal's nominal maximum transmission power using a combination of absolute and difference values ​​can save on the number of bits reported or improve the accuracy of the reporting.

[0142] In this embodiment of the application, the scenario in which a terminal reports multiple terminal nominal maximum transmission powers to the network-side device may include one of the following:

[0143] 1) The number of terminals reporting multiple nominal maximum transmission powers is less than the number of multiple PHs;

[0144] 2) The multiple terminal nominal maximum transmission power reported by the terminal corresponds one-to-one with these multiple PHs.

[0145] In this embodiment, the nominal maximum transmission power of one or more terminals reported by the terminal can also be reported via MAC CE. This will be explained in detail below with reference to Figures 5 and 6.

[0146] Figure 5 illustrates a scenario where a terminal reports multiple power phony (PH) values ​​and a terminal's nominal maximum transmission power to the network-side equipment. The MAC CE (Configuration Entity CE) consists of multiple 8-bit bytes of variable size, determined by the number of active power ciphers (FPs) configured or activated in the first serving cell. The first to Nth bytes of the MAC CE are used to report PH 1 to PH N, a total of N PHs. These N PHs correspond one-to-one with the N FPs, i.e., FP 0 to FP(N-1). The (N+1)th byte of the MAC CE is used to report the terminal's nominal maximum transmission power P. CMAX,c .

[0147] In Figure 5, FP can also be replaced by FP associations, where N PHs correspond one-to-one with N FP associations, and the terminal reports the N PHs corresponding to the N FP associations to the network-side equipment. Accordingly, the size of MAC CE can be determined by the number of FP associations configured or activated in the first serving cell, which will not be discussed further here.

[0148] Among them, the nominal maximum transmission power P of the above-mentioned terminal CMAX,c This may include: the nominal maximum transmission power of the terminal corresponding to the first serving cell; or, the nominal maximum transmission power of the terminal corresponding to the target carrier (such as all carriers) of the first serving cell; or, the nominal maximum transmission power of the terminal corresponding to the target FP (such as all configured or activated FPs) or the combination of target FPs (such as the combination of all configured or activated FPs) of the first serving cell; the specifics are not limited.

[0149] Figure 6 illustrates a scenario where a terminal reports multiple Personal Notices (PHs) and multiple terminal nominal maximum transmission powers to the network-side equipment. The MAC CE consists of multiple 8-bit bytes, with a variable size determined by the number of Front Serving Cells (FPs) configured or activated in the first serving cell. The first to the 2Nth bytes of the MAC CE are used to report the PHs corresponding to the N FPs and the terminal's nominal maximum transmission power, respectively, including: PH1, P... CMAX,f,c 0, pH 2, P CMAX,f,c 1, ..., PH N, P CMAX,f,c N-1. These N FPs include FP0 to FP(N-1).

[0150] In Figure 6, FP can also be replaced by FP combinations, where N PHs correspond one-to-one with N FP combinations. The terminal reports the N PHs corresponding to the N FP combinations and the N terminal nominal maximum transmission power to the network-side equipment. Accordingly, the size of MAC CE can be determined by the number of FP combinations configured or activated in the first serving cell, which will not be discussed further here.

[0151] Among them, the nominal maximum transmission power P of the above-mentioned terminal CMAX,f,c This may include: different FPs or FP combinations in the first serving cell may correspond to the same terminal nominal maximum transmission power; or, they may correspond to different terminal nominal maximum transmission powers; the specifics are not limited.

[0152] The following explanation is provided regarding the various parameters in the MAC CE shown in Figures 5 and 6 above.

[0153] In MAC CE, the P field indicates whether the P-MPR applied to meet MPE requirements satisfies a specific threshold (e.g., P-MPR_00), or indicates the corresponding P... CMAX,c or P CMAX,f,c This value indicates whether power rollback occurred due to power management. For example, a value of 1 in this field indicates that power rollback resulted in P... CMAX,c or P CMAX,f,c The value changes, with 0 indicating no power backoff. Specifically, its definition can follow existing NR protocols. For example, if the UE is configured to report MPE P-MPR in the PHR MAC CE (e.g., the parameter mp-reporting-FR2 is configured), and the serving cell is operating on FR2, then to meet the MPE requirements specified in the relevant protocols, if the applied P-MPR value is less than a predefined value (e.g., P-MPR_00 specified in the relevant protocols), the MAC entity sets this field to 0; otherwise, it sets it to 1. If MPE P-MPR reporting in the PHR MAC CE is not configured (e.g., the parameter mpe-reporting-FR2 is not configured), or the serving cell is operating on FR1, then this field indicates whether power backoff has been applied due to power management. For another example, if the corresponding P... CMAX,c or P CMAX,f,c M has different values ​​because power management does not have power backoff. The MAC entity sets the P field to 1 if the corresponding P... CMAX,c or P CMAX,f,c field would have had a different value if no power backoff due to power management had been applied).

[0154] In MAC CE, the V field indicates whether the corresponding PH value is based on actual transmission or a reference format. For example, for Type 1 PHR, a V field of 0 indicates actual transmission on PUSCH, and a V field of 1 indicates the use of the PUSCH reference format. For Type 2 PHR, a V field of 0 indicates actual transmission on PUCCH, and a V field of 1 indicates the use of the PUCCH reference format. For Type 3 PHR, a V field of 0 indicates actual transmission on SRS, and a V field of 1 indicates the use of the SRS reference format.

[0155] In MAC CE, the R field is a reserved bit, for example, it can be set to 0.

[0156] In the MAC CE, the power margin i (PH i, i = 1, ..., N) field represents the power margin level, indicating the PH value corresponding to the i-th configured or activated FP or FP union. The PH fields of the first serving cell are arranged in ascending order of i, and the field length is X, which can be less than or equal to 8 bits, such as 6 bits, etc., without specific limitation. The relationship between the reported PH value and the corresponding power margin level can be predefined, as shown in Table 1. The PH reported by the terminal can be Type 1 / 2 / 3 PH or other types.

[0157] Table 1

[0158] In Table 1, the pH values ​​0 to 63 are the values ​​of the pH field in Figure 5 or Figure 6, and the corresponding power margin levels POWER_HEADROOM_0 to POWER_HEADROOM_63 are the actual values ​​of the power margin.

[0159] Among them, P in MAC CE CMAX,c and P CMAX,f,c The field represents the terminal's nominal maximum transmission power used to calculate the aforementioned PH field. The relationship between the terminal's nominal maximum transmission power and the corresponding terminal nominal maximum transmission power level can be predefined, P CMAX,c or P CMAX,f,c The relationship between the corresponding terminal's nominal maximum transmission power level can be shown in Table 2.

[0160] Table 2

[0161] Among them, P is shown in Table 2. CMAX,c or P CMAX,f,c Values ​​0-63 represent P in Figure 5. CMAX,c The value of the field or P in Figure 6 CMAX,f,cThe value of the field corresponds to the terminal's nominal maximum transmission power level PCMAX_C_0~PCMAX_C_63, which is the actual value of the terminal's nominal maximum transmission power.

[0162] For example, a serving cell is configured to include 5 FPs, FP#0-FP#4. The UE uses one PA to cover 3 FPs, FP#0-FP#2, and the other two FPs are covered by two other PAs respectively. In one implementation, the UE reports capability information to the base station, and the base station determines FP combinations based on the reported capability information, specifically as follows: FP combination 0 includes FP#0-FP#2, FP combination 1 includes FP#3, and FP combination 2 includes FP#4. The UE reports its corresponding PA for each FP combination in FP combination 0-2. CMAX,f,c In another implementation, the base station can explicitly configure FP combinations or determine FP combinations using predefined rules. For example, FP combination 0 includes FP#0-FP#2, while FP#3 and FP#4 remain independent FPs. In this case, the UE can report the corresponding FPs for FP combination 0, FP#3, and FP#4 respectively. CMAX,f,c .

[0163] The MPE (Maximum Permissible Exposure) field in the MAC CE indicates whether the applied power backoff meets predefined requirements or whether power backoff has been applied. For example, its definition can follow existing NR protocols. If the UE is configured to report MPE P-MPR in the PHR MAC CE (e.g., with parameter mp-reporting-FR2 configured), and the serving cell is operating on FR2, then with the P field set to 1, the MPE field indicates that the applied power backoff meets the MPE requirements, and this field is 2 bits long. If the UE is not configured to report MPE P-MPR in the PHR MAC CE (e.g., without parameter mp-reporting-FR2 configured), or the serving cell is operating on FR1, or the P field is set to 0, then the MPE field has R bits (if the P field is set to 0, R bits are present instead). The MPE field and the corresponding measured values ​​of the P-MPR level in dB are shown in Table 3.

[0164] Table 3

[0165] In Table 3, the MPE values ​​0 to 3 are the values ​​of the MPE field in Figure 5 or Figure 6, and the corresponding P-MPR measurement values ​​P-MPR_00 to P-MPR_03 are the actual measured values ​​of P-MPR.

[0166] In this embodiment, the UE may simultaneously perform multiple UL transmissions on different FPs within a serving cell. For example, each FP / FP alliance may transmit one PUCCH, PUSCH, or SRS, and the UL types (such as PUCCH, PUSCH, SRS, PTRS, etc. UL channels or signals) transmitted between different FP / FP alliances can be independent. Alternatively, the UE may transmit more than one UL type (such as PUCCH or PUSCH, and also SRS) on different FP / FP alliances. For example, if a serving cell is configured and activated with 3 FPs, the UE may simultaneously perform at least one of the following transmission combinations on the 3 FPs:

[0167] 1) PUCCH, PUCCH, PUCCH;

[0168] 2) PUSCH, PUSCH, PUSCH;

[0169] 3) SRS, SRS, SRS;

[0170] 4) PUCCH, PUSCH, PUSCH;

[0171] 5) PUCCH, SRS, SRS;

[0172] 6) PUSCH, PUSCH, SRS;

[0173] 7) PUCCH, PUSCH, SRS;

[0174] 8) PUCCH, PUCCH, PUSCH;

[0175] 9) PUCCH, PUCCH, SRS;

[0176] 10) PUSCH, SRS, SRS.

[0177] The above combinations are merely illustrative examples. In actual applications, various other combinations can be used as needed, which will not be elaborated here.

[0178] In this embodiment, the PH reported by the terminal can be calculated based on different estimated transmission powers. Specifically, the estimated uplink transmission power of each FP or FP group configured or activated in the first serving cell can be calculated in at least one of the following ways:

[0179] 1) If there is uplink transmission on a FP, determine the estimated uplink transmission power based on the actual transmission of the FP;

[0180] 2) If there is uplink transmission on an FP alliance, determine the estimated uplink transmission power based on the actual transmission of the FP alliance;

[0181] 3) If there is no uplink transmission on a FP, determine the estimated uplink transmission power based on the FP's reference format;

[0182] 4) If there is no uplink transmission on an FP union, determine the estimated uplink transmission power based on the reference format of the FP union.

[0183] In this embodiment of the application, if there is no uplink transmission on a FP, determining the estimated uplink transmission power based on the FP's reference format can include one of the following:

[0184] 1) If there is no uplink transmission on a FP, determine the estimated uplink transmission power based on the reference PUSCH transmission.

[0185] 2) If there is no uplink transmission on a FP, but the FP is configured with PUCCH resources or configured to transmit PUCCH, determine the estimated uplink transmission power based on the reference PUCCH transmission.

[0186] 3) If there is no uplink transmission on a FP, the estimated uplink transmission power is determined based on the configuration information of the network-side device to determine which type of uplink transmission reference format to use.

[0187] In this embodiment of the application, if there is no uplink transmission on a FP alliance, determining the estimated uplink transmission power based on the reference format of the FP alliance may include one of the following:

[0188] 1) If there is no uplink transmission on a FP federation, the estimated uplink transmission power is determined based on the reference UL-SCH transmission.

[0189] 2) If there is no uplink transmission on an FP alliance, but the FP alliance is configured with PUCCH resources or configured to transmit PUCCH, determine the estimated uplink transmission power based on the reference PUCCH transmission.

[0190] 3) If an FP federation has no uplink transmission, the estimated uplink transmission power P is determined based on the configuration information of the network-side devices to determine the reference format for which type of uplink transmission is used. i .

[0191] In this embodiment of the application, there may be multiple FPs or FP associations configured or activated in the first serving cell. The following describes the process of calculating the estimated transmission power by taking one of them, such as the i-th one, as an example.

[0192] If there is PUSCH transmission on an FP or FP alliance, the estimated uplink transmission power is determined based on the actual PUSCH transmission of that FP or FP alliance as follows:

[0193] If there is no PUSCH transmission on an FP or FP alliance, the estimated uplink transmission power is determined based on the reference format of that FP or FP alliance as follows: P i =P O_PUSCH,f,c (j)+α f,c (j)·PL f,c (q d )+f f,c (i,l).

[0194] If there is PUCCH transmission on an FP or FP alliance, the estimated uplink transmission power is determined based on the actual PUCCH transmission of that FP or FP alliance as follows:

[0195] If an FP or FP alliance has no PUCCH transmission, the estimated uplink transmission power is determined based on the reference PUCCH transmission of that FP or FP alliance as follows: P i =P O_PUCCH,f,c (q u )+10log 10 (PL f,c (q d )+g f,c (i,l)).

[0196] If there is SRS transmission on a FP or FP alliance, the estimated uplink transmission power is determined based on the actual SRS transmission of that FP or FP alliance as follows: P i =P O_SRS,f,c (q s )+10log 10 (2 μ ·M SRS,f,c (i))+α SRS,f,c (q s ) · PL f,c (q d )+h f,c (i).

[0197] If there is no SRS transmission on a FP or FP alliance, the estimated uplink transmission power is determined based on the reference SRS transmission of that FP or FP alliance as follows: P i =P O_SRS,f,c (q s )+α SRS,f,c (q s )·PL f,c (q d)+h f,c (i).

[0198] The parameters involved in the above formulas are explained as follows:

[0199] P O_PUSCH,f,c P O_PUCCH,f,c P O_SRS,f,c This represents the target received power under open-loop control, which can be configured or specified by the base station.
