Description

Technical Field

[0001] This application belongs to the field of wireless communication technology, specifically relating to an uplink transmission power control method, a terminal, and a network-side device. Background Technology

[0002] Sub-3GHz spectrum offers advantages such as wide coverage and low penetration loss, playing a crucial role in cellular network deployment due to its excellent coverage performance. Currently, however, Sub-3GHz spectrum is fragmented and allocated to different wireless communication systems. Furthermore, competition among mobile operators further exacerbates the fragmentation and discretization of spectrum available to each operator.

[0003] Given the current state of spectrum dispersion or fragmentation, one possible approach is to aggregate multiple discrete spectrums into a single cell.

[0067] Δ TF,b,f,c (i) indicates the power adjustment amount related to the number of bits in the PUCCH, which is determined based on the number of bits occupied per unit symbol or per unit bandwidth. For details, please refer to the relevant NR protocol specifications.

[0071] In this embodiment of the application, the formula for calculating the transmission power of SRS can be expressed as follows:

[0072]

[0073] Among them, P SRS,b,f,c (i,q s ,l) represents the transmission power of SRS, which is the power at time i of the SRS transmission in the l-th state of the serving cell c, carrier f and uplink bandwidth b.

[0081] The uplink transmission power control method, terminal, and network-side equipment provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0082] Figure 2 This diagram illustrates a flowchart of an uplink transmission power control method provided in an embodiment of this application, which can be executed by a terminal. Figure 2 As shown, the method may include the following steps.

[0083] S202: The terminal uses a first method and / or a second method to determine the transmission power of the first uplink transmission for the first serving cell; and / or, the terminal uses a third method to reduce the transmission power of the first uplink transmission for the first serving cell.

[0084] The first serving cell is configured to include at least one frequency part (FP), with a first mode being a control mode based on uplink transmission (per serving cell) and a second mode being a control mode based on FP (per FP) or based on FP combination (per FP combination).

[0085] In this embodiment, FP can be a set of continuous frequency domain resources, and FP can be any of the following: band, carrier, subband, bandwidth part (BWP), or frequency range (FR). The frequency range (FR) can be predefined by the protocol or reported by the terminal to the network-side device.

[0086] 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.

[0087] In the embodiments of this application, a FP union includes at least one FP, which may include one FP or multiple FPs, and can be configured, defined or determined as needed, without specific limitation.

[0088] Figure 3 A schematic diagram of an FP configuration provided in an embodiment of this application is shown. See also... Figure 3 The first serving cell is configured with six frequency bands (FPs), including FP1 through FP6. FP1 and FP2 correspond to band i, FP3 and FP4 to band j, and FP5 and FP6 to band k. For example, the base station can configure FP1 and FP2 to form FP combination 1, FP3 and FP4 to form FP combination 2, and 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 there are no specific limitations.

[0089] In this embodiment of the application, the first uplink transmission may include at least one of the following: PUCCH, PUSCH, SRS, and Physical Random Access Channel (PRACH).

[0090] In this embodiment, the first method does not require control of uplink transmission power based on FP or FP combination, but rather control is based on uplink transmission. The first method may include at least one of the following:

[0091] 1) If the terminal transmits at least one first uplink transmission on at least one FP, the transmission power of each first uplink transmission is determined separately. Optionally, the first power control parameters for each first uplink transmission are the same or determined separately. The first power control parameters for the first uplink transmission include at least one of the following: the terminal's maximum transmission power P. CMAX The nominal power P corresponding to the first uplink transmission O_PUSCH P O_PUCCH or P O_SRS(Representing the target received power under open-loop control), path loss compensation factor, reference signal (RS) for downlink path loss estimation of the first uplink transmission, transmit power control (TPC) command, energy per resource element (EPRE), and power spectral density (PSD). Optionally, a third power control parameter for each first uplink transmission can be determined separately, wherein the third power control parameter for the first uplink transmission includes at least one of the following: TPC command, EPRE, PSD, MCS, PRB number, and power adjustment factor related to the PUCCH format.

[0092] This scenario includes cases where the first uplink transmission is carried out on multiple FPs. Regardless of the number of FPs involved, all FPs can use the same first power control parameters. For example, if the terminal transmits the first uplink on 5 FPs, the terminal determines a transmission power for the first uplink transmission, and the first power control parameters for the first uplink transmission across these 5 FPs are the same. Specifically, the EPRE (Electronic Power Precision) for the first uplink transmission across these 5 FPs is identical. As another example, if the terminal transmits the first uplink on 3 FPs, the nominal power of the first uplink transmission across these 3 FPs is the same, and the first uplink transmission across these 3 FPs corresponds to a single TPC command.

[0093] The reference signals used for downlink path loss estimation in the first uplink transmission include, but are not limited to: SSB, and / or, CSI-RS.

[0094] In one implementation, the terminal transmits multiple first uplink transmissions on a single FP. The transmission power of each first uplink transmission can be determined separately, and the first power control parameters for each first uplink transmission can be the same or determined separately. For example, the terminal transmits three uplink transmissions within a single FP. These three uplink transmissions may each have their own UE nominal maximum transmission power, path loss compensation factor, and downlink path loss estimation reference signal (wherein the downlink path loss estimation reference signal is mainly applicable to uplink transmissions of the same type).

[0095] 2) If the terminal transmits at least one first uplink transmission on at least one FP alliance, the transmission power of each first uplink transmission is determined separately. Optionally, the first power control parameters for each first uplink transmission are the same or determined separately. The first power control parameters for the first uplink transmission include at least one of the following: the terminal's maximum transmission power, the nominal power corresponding to the first uplink transmission, the path loss compensation factor, the RS, TPC command, EPRE, and PSD used for downlink path loss estimation of the first uplink transmission. Optionally, the third power control parameter for each first uplink transmission can be determined separately, wherein the third power control parameter for the first uplink transmission includes at least one of the following: TPC command, EPRE, PSD, MCS, PRB number, and a power adjustment factor related to the PUCCH format.

[0096] This scenario includes cases where the first uplink transmission is transmitted over multiple FP (Field-Programmable) associations. Regardless of the number of FP associations involved in the uplink transmission, all FP associations can use the same first power control parameter and / or different third power control parameters. For example, if the terminal transmits the first uplink transmission over 5 FP associations, the terminal determines a transmission power for the first uplink transmission, and the first power control parameters corresponding to the first uplink transmissions within these 5 FP associations are the same. Specifically, the EPRE (Electronic Power Control Parameter) of the first uplink transmissions within these 5 FP associations is the same. As another example, if the terminal transmits the first uplink transmission over 3 FP associations, the nominal power of the first uplink transmissions within these 3 FP associations is the same, and the first uplink transmissions within these 3 FP associations correspond to a single TPC (Transmission Control Program) command.

[0097] In one implementation, the terminal transmits multiple first uplink transmissions on a FP association, the transmission power of each first uplink transmission can be determined separately, and the first power control parameters of each first uplink transmission can be the same or determined separately.

[0098] The first method described above does not require distinguishing between controlling the transmission power of FP or FP combined, regardless of the specific scenario, making the control method simpler and more flexible.

[0099] In this embodiment, the second method controls uplink transmission power based on FP or a combination of FP. The second method may include at least one of the following:

[0100] 1) If the terminal transmits the first uplink transmission on at least one FP, the transmission power of the first uplink transmission within each FP is determined separately. In this scenario, the control granularity is FP-based, and the transmission power of the first uplink transmission within each FP is determined individually.

[0101] The transmission power of the first uplink transmission within each FP can be the same or different, without specific limitations. For example, when transmitting the first uplink transmission on four FPs, the transmission power of the first uplink transmission in FP1 and FP2 is the same, while the transmission power of the first uplink transmission in FP3 and FP4 is different, and also different from the transmission power of the first uplink transmission in FP1 and FP2. As another example, when transmitting the first uplink transmission on three FPs, the transmission power of the first uplink transmission in FP1, FP2, and FP3 is different.

[0102] In this FP-based granularity scenario, some control parameters of the first uplink transmission can be the same, such as the terminal's maximum transmission power; while some control parameters can be different, such as the RS and TPC commands used for downlink path loss estimation in the first uplink transmission, the MCS of the first uplink transmission, and the number of PRBs.

[0103] 2) If the terminal transmits the first uplink transmission on at least one FP association, the transmission power of the first uplink transmission within each FP association is determined separately. In this scenario, the control granularity is based on FP associations, and the transmission power of the first uplink transmission within each FP association is determined individually.

[0104] Within each FP alliance, the transmission power of the first uplink transmission can be the same or different, without specific limitations. For example, the first uplink transmission can be transmitted across 5 FP alliances, where the transmission power of the first uplink transmission within each FP alliance is different. Alternatively, the transmission power of the first uplink transmission within FP alliance 1 and FP alliance 3 can be the same, while the transmission power of the first uplink transmission within FP alliance 2, FP alliance 4, and FP alliance 5 can be different.

[0105] In this FP-based joint granularity scenario, some control parameters of the first uplink transmission can be the same, such as the terminal's maximum transmission power; while some control parameters can be different, such as the RS, TPC command, MCS, and PRB number used for downlink path loss estimation in the first uplink transmission.

[0106] 3) If a terminal transmits multiple first uplink transmissions within a single FP, and the transmission power of these multiple first uplink transmissions within a single FP is the same, then the transmission power of each first uplink transmission within the FP should be determined individually. For example, if a terminal transmits three first uplink transmissions within a single FP, their transmission power or EPRE should all be the same.

[0107] 4) If a terminal transmits multiple first uplink transmissions within an FP association, and the transmission power of these multiple first uplink transmissions within an FP association is the same, then the transmission power of the first uplink transmission within the FP association should be determined individually. For example, if a terminal transmits five first uplink transmissions within an FP association, their transmission power or EPRE should all be the same.

[0108] The second method described above can precisely control the uplink transmission power of FP and / or FP combined, regardless of the specific scenario, with higher control precision and finer granularity.

[0109] In this application embodiment, the first method and the second method belong to the control methods based on uplink transmission and FP (per FP per UL or per UL per FP), or the control methods based on uplink transmission and FP combination (per UL per FP combination or per FP combination per UL). The first method and the second method may include at least one of the following:

[0110] 1) If a terminal transmits multiple first uplink transmissions within a FP, the transmission power of the multiple first uplink transmissions within the FP is determined respectively.

[0111] Optionally, the first power control parameters for multiple first uplink transmissions within a single FP can be identical, while the second power control parameters can be determined separately. The first power control parameter may include at least one of the following: UE nominal maximum transmission power, downlink path loss compensation factor, and downlink path loss estimation reference signal. The second power control parameter may include at least one of the following: TPC command, MCS, PRB number, EPRE, and downlink path loss estimation reference signal.

[0112] For example, a terminal transmits three first uplink transmissions within a FP, wherein the transmission power of the three first uplink transmissions within the FP is determined separately and can be different for each.

[0113] 2) If a terminal transmits multiple first uplink transmissions within a single FP association, the transmission power of each of the multiple first uplink transmissions within the single FP association is determined.

[0114] For example, a terminal transmits five first uplink transmissions within a FP association. The transmission power of the five first uplink transmissions within the FP association is determined separately and can all be different; or, three of the first uplink transmissions have the same transmission power, while the other two have different transmission powers, etc., and there is no specific limitation.

[0115] Optionally, the first power control parameters of multiple first uplink transmissions within a single FP alliance can be identical, while the second power control parameters can be determined separately. The first power control parameter may include at least one of the following: UE nominal maximum transmission power, downlink path loss compensation factor, and downlink path loss estimation reference signal. The second power control parameter may include at least one of the following: TPC command, MCS, PRB number, EPRE, and downlink path loss estimation reference signal.

[0116] 3) If the terminal transmits multiple first uplink transmissions in multiple FPs, the transmission power of the multiple first uplink transmissions in the multiple FPs is determined respectively, and the second power control parameters of the multiple first uplink transmissions in any one of the multiple FPs are the same.

[0117] 4) If the terminal transmits multiple first uplink transmissions within multiple FP associations, the transmission power of the multiple first uplink transmissions within the multiple FP associations is determined respectively, and the second power control parameters of the multiple first uplink transmissions within any FP association are the same.

[0118] In this application embodiment, when using the second method, or when using both the first and second methods, various application scenarios can be included in specific implementations, providing multi-scenario solutions for uplink transmission power control. Accordingly, the above method may include at least one of the following:

[0119] 1) Multiple first uplink transmissions within a single FP are of the same type, such as all being PUCCH, PUSCH, or SRS.

[0120] 2) Multiple first uplink transmissions within an FP association have the same type, such as PUCCH, SRS, or PRACH.

[0121] 3) Multiple first uplink transmissions within a FP are multiple uplink transmissions scheduled by a DCI, such as PUCCH, PUSCH, and PRACH scheduled by a DCI.

[0122] 4) Multiple first uplink transmissions within a single FP are multiple repeated transmissions of a single uplink transmission, such as multiple repeated transmissions of a single PUCCH.

[0123] 5) Multiple first uplink transmissions within an FP federation are multiple uplink transmissions scheduled by a DCI, such as PUCCH, PUSCH, SRS, and PRACH scheduled by a DCI.

[0124] 6) Multiple first uplink transmissions within an FP association are multiple repetitions of a single uplink transmission, such as multiple repetitions of an SRS.

[0125] In this embodiment of the application, the method may further include: the terminal reporting capability information to the network-side device. The capability information reported by the terminal may include one of the following:

[0126] 1) The number of power amplifiers (PAs) used by the terminal for the first serving cell.

[0127] 2) FP information covered by the PA used by the terminal for the first serving cell; for example, information on several FPs covered by a PA, and / or information on FPs covered by a PA, such as FP index, number and frequency domain location, etc.

[0128] 3) The FP combination information covered by the PA used by the terminal for the first serving cell; such as how many FPs the PA covers, and which FPs are included in the combination, etc.

[0129] 4) The terminal uses one PA to cover all FPs of the first serving cell. In this scenario, the terminal has a small number of PAs, but the frequency coverage requirement of the PAs is large.

[0130] 5) The terminal uses multiple PAs to cover all FPs of the first serving cell, and each PA covers one FP. For example, if the first serving cell is configured with 3 FPs, the terminal uses 3 PAs, and each PA covers one FP.

[0131] 6) The terminal uses multiple PAs to cover all FP combinations of the first serving cell, and each PA covers one FP combination. For example, the terminal uses 5 PAs to cover 5 FP combinations of the first serving cell, and each PA covers one FP combination.

[0132] 7) The terminal uses multiple PAs to cover all FPs of the first serving cell and the FP information covered by each PA, such as how many FPs each PA covers, and which FPs are included.

[0133] 8) The terminal uses multiple PAs to cover all FP combinations of the first serving cell and the FP combination information covered by each PA, such as how many FP combinations each PA covers, and which FP combinations are specifically included.

[0134] In this embodiment of the application, the above method may further include at least one of the following:

[0135] 1) Determine whether to use the first or second method based on the terminal's capabilities;

[0136] 2) Determine whether to use the first or second method based on the configuration or instructions of the network-side equipment;

[0137] 3) Determine whether to use the first mode or the second mode based on the type of the first uplink transmission.

[0138] Specifically, determining whether to use the first or second method based on the terminal's capabilities can include:

[0139] 1) If the terminal uses 1 PA for the first serving cell or the terminal uses one PA to cover all FPs of the first serving cell, the terminal determines the transmission power of the first uplink transmission using the first method for the first serving cell.

[0140] In this scenario, there is no need to distinguish between controlling the uplink transmission power on the FP or the FP combination, making the control method simpler.

[0141] 2) If the terminal uses more than 1 PA for the first serving cell or the terminal uses multiple PAs to cover all FPs of the first serving cell and each PA covers one FP, the terminal determines the transmission power of the first uplink transmission for the first serving cell based on the FP.

[0142] This scenario falls under the second approach, where uplink transmission power is controlled at the FP (Power Frame) level, offering higher control precision compared to the first approach.

[0143] 3) If the terminal uses more than 1 PA for the first serving cell or the terminal uses multiple PAs to cover all FP combinations of the first serving cell and each PA covers one FP combination, the terminal determines the transmission power of the first uplink transmission based on the FP combination for the first serving cell.

[0144] This scenario represents another application of the second approach, where uplink transmission power is controlled at the granularity of FP (Feature-Power Consortium) integration, resulting in higher control precision compared to the first approach.

[0145] The method provided in this application embodiment involves a terminal determining the transmission power of a first uplink transmission using a first method and / or a second method for a first serving cell; and / or, a terminal reducing the transmission power of the first uplink transmission using a third method for the first serving cell. The first serving cell is configured to include at least one FP (Feature Function). The first method is an uplink transmission-based control method, and the second method is an FP-based or FP-based combined control method. This provides a solution for uplink transmission power control and transmission power reduction for a single cell that aggregates multiple discrete spectrums, which is beneficial for improving the effectiveness and flexibility of transmission power control association functions.

[0146] Figure 4 This diagram illustrates a flowchart of an uplink transmission power control method provided in an embodiment of this application, which can be executed by a terminal. Figure 4 As shown, the method may include the following steps.

[0147] S402: For the first transmission timing of the first serving cell, if the total power of all first uplink transmissions in the target frequency domain cell exceeds the maximum transmission power corresponding to the target frequency domain cell, the terminal reduces the transmission power of the first uplink transmission according to a preset principle so that the total power of all first uplink transmissions in the target frequency domain cell does not exceed the maximum transmission power corresponding to the target frequency domain cell.

[0148] The first serving cell is configured to include at least one FP. The target frequency domain element includes the first serving cell, or the target frequency domain element includes at least one of the following sub-elements of the first serving cell: FP, FP combination, and frequency range FR.

[0149] 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.

[0150] In this embodiment, FP can be a set of continuous frequency domain resources, and FP can be any of the following: frequency band, carrier, subband, partial bandwidth, or frequency range. The frequency range can be predefined by the protocol or reported by the terminal to the network-side device.

[0151] In this embodiment of the application, a FP union includes at least one FP, which may include one FP or multiple FPs, and can be configured as needed, without specific limitations.

[0152] In this embodiment of the application, the first uplink transmission within the target frequency domain unit may include at least one of the following: PUCCH, PUSCH, SRS, PRACH.

[0153] In this embodiment, the first transmission timing can be defined by the slot index within a frame with a System Frame Number (SFN), such as the first symbol s and the number of consecutive symbols L within the slot corresponding to n_(s,f)^μ. For PUSCH transmissions with repetition type B, the PUSCH transmission timing is nominally repetitive.

[0154] In one implementation, multiple FPs in the first serving cell may use the same PA. In this case, different uplink transmissions on the first serving cell share a single PA. When the total power of all uplink transmissions on the first serving cell exceeds the maximum transmission power of the UE, the UE reduces its power.

[0155] In another implementation, multiple FPs in the first serving cell correspond to multiple PAs. In this case, different FPs on the first serving cell can be divided into different frequency domain ranges or FP combinations, such as a frequency domain range or a FP combination sharing a single PA. In this situation, if the total uplink transmission power of the UE exceeds the maximum power of that frequency domain range or FP combination within a frequency domain range or FP combination, the uplink transmission power of the UE within that frequency domain range or FP combination will be reduced.

[0156] In this embodiment of the application, the preset principle used by the terminal to reduce the transmission power of the first uplink transmission may include at least one of the following:

[0157] 1) First principle: Prioritize allocating the transmission power of the first uplink transmission in the first sub-unit of the target frequency domain unit, and then allocate the transmission power of the first uplink transmission in other sub-units besides the first sub-unit. The first sub-unit includes at least one of the following: main FP, default FP, main FP combination, and default FP combination.

[0158] The first sub-unit can be one or more sub-units of the target frequency domain unit. For example, the first sub-unit includes the main FP and the main FP combination, while the FP, FP combination and frequency range other than the main FP and the main FP combination are other sub-units.

[0159] At least one of the above-mentioned primary FP, default FP, primary FP combination, and default FP combination can be configured by network-side devices or determined by a predefined method.

[0160] For example, the FP with the smallest FP index is the primary FP or the default FP; the FP union with the smallest FP union index is the primary FP union or the default FP union; the FP configured for SSB transmission is the primary FP or the default FP; the FP union configured for SSB transmission is the primary FP union or the default FP union, etc.

[0161] This approach prioritizes the transmission power of uplink transmissions within a specified sub-unit, provided that the total power of all first uplink transmissions within the target frequency domain unit does not exceed the maximum transmission power corresponding to the target frequency domain unit.

[0162] 2) Second principle: Divide the terminal’s maximum transmission power into multiple parts (hard split) and allocate them one by one to each sub-unit in the target frequency domain unit, and determine the maximum transmission power corresponding to each sub-unit.

[0163] The maximum transmission power of the terminal can be divided in any of the following ways: divided into multiple parts proportionally according to each sub-unit, or divided into multiple parts according to the bandwidth of each sub-unit.

[0164] For example, for the first transmission timing of the first serving cell, the target frequency domain unit includes the four FPs configured in the first serving cell. If the total power of all first uplink transmissions within the target frequency domain unit exceeds the maximum transmission power corresponding to the target frequency domain unit, then the maximum transmission power P of the terminal can be reduced. CMAX Each of the four photonic units (FPs) is allocated 25% of the total power, therefore the maximum transmission power for each FP is 25% of the total power. CMAX .

[0165] For example, regarding the first transmission timing of the first serving cell, the target frequency domain unit includes the three FPs configured in the first serving cell. If the total power of all first uplink transmissions within the target frequency domain unit exceeds the maximum transmission power corresponding to the target frequency domain unit, then the terminal's maximum transmission power P can be set to... CMAX The bandwidth is divided according to the three process nodes (FPs). The number of backhaul blocks (PRBs) within each of the three FPs are M1, M2, and M3, respectively, or their frequency domain bandwidths are M1, M2, and M3 MHz. Therefore, the maximum transmission power for each of the three FPs is: M1 / (M1+M2+M3)*P. CMAX M2 / (M1+M2+M3)*P CMAX M3 / (M1+M2+M3)*P CMAX .

[0166] 3) Third principle: Reduce the transmission power of each first uplink transmission within the target frequency domain unit proportionally.

[0167] For example, if the target frequency domain unit includes 5 sub-units, the transmission power of the first uplink transmission of each sub-unit can be reduced by X%, so that the total power of all first uplink transmissions in the target frequency domain unit after the reduction does not exceed the maximum transmission power corresponding to the target frequency domain unit.

[0168] In this embodiment of the application, the first principle may further include at least one of the following:

[0169] 1) The transmission power of the first uplink transmission within the first sub-unit does not exceed the first threshold.

[0170] The first threshold can be set as needed or configured by higher-level parameters, and the specific value is not limited.

[0171] 2) If the transmission power of the specified uplink transmission is lower than the second threshold, the terminal will not perform the specified uplink transmission.

[0172] Specifically, it may include one of the following:

[0173] If the total power of the first uplink transmission in the sub-units other than the first sub-unit is lower than the second threshold, the terminal will not perform the first uplink transmission in the other sub-units; or,

[0174] In subunits other than the first subunit, if the transmission power of the first uplink transmission in the second subunit is lower than the second threshold, the terminal will not transmit the first uplink transmission in the second subunit.

[0175] In this embodiment, the preset principle of reducing uplink transmission power of the terminal can be combined with the original principle of reducing uplink transmission power of the terminal, and the order of combination is not limited.

[0176] The original principles for reducing uplink transmission power in terminals include several principles in the following order:

[0177] 1) PRACH transmission on PCell;

[0178] 2) Transmission of PUCCH or PUSCH with higher priority index;

[0179] 3) For PUCCH or PUSCH transmissions with the same priority index;

[0180] 31) PUCCH transmission with HARQ-ACK information, and / or SR, and / or LRR transmission, or PUSCH transmission with HARQ-ACK information with this priority index;

[0181] 32) PUCCH transmission with CSI or PUSCH transmission with CSI;

[0182] 33) PUSCH transmission without HARQ-ACK information or without CSI, or PUSCH transmission on PCell for Type-2 random access procedures.

[0183] 4) If the terminal is configured to prioritize PRACH transmission on the SCell over semi-persistent and / or periodic SRS transmission, for example, if the UE is configured with the parameter priorocellprach-overspperiodicsr;

[0184] 41) Perform aperiodic SRS or PRACH transmissions on serving cells other than PCell;

[0185] 42) Semi-persistent and / or periodic SRS transmission;

[0186] 5) If the terminal is not configured to prioritize PRACH transmissions on the Scell ​​over semi-persistent / periodic CSI transmissions; 51) SRS transmissions, non-periodic SRS have higher priority than semi-persistent and / or periodic SRS, or PRACH transmissions on the serving cell outside the PCell.

[0187] Furthermore, under the same priority order and carrier aggregation operation, the transmission power allocation on the primary cell of the MCG or SCG takes precedence over the transmission power allocation on the secondary cell. When there are two UL carriers with the same priority order, transmission power is preferentially allocated on the carrier configured to transmit PUCCH. If neither of the two UL carriers is configured with PUCCH, the transmission power of the non-supplementary UL carrier is preferentially allocated.

[0188] The following example illustrates how the preset principle of reducing uplink transmission power in the terminal is combined with the original principle of reducing uplink transmission power in the terminal.

[0189] In one example, the principle for a terminal to reduce uplink transmission power may include the following order:

[0190] 1) PRACH transmission on PCell;

[0191] 2) Transmission of PUCCH or PUSCH with higher priority index;

[0192] 3) For PUCCH or PUSCH transmissions with the same priority index;

[0193] 31) PUCCH or PUSCH transmission on the primary FP or the primary FP assembly;

[0194] 32) PUCCH transmission with HARQ-ACK information, and / or SR, and / or LRR transmission, or PUSCH transmission with HARQ-ACK information with this priority index;

[0195] 33) PUCCH transmission with CSI or PUSCH transmission with CSI;

[0196] 34) PUSCH transmission without HARQ-ACK information or without CSI for Type-2 random access procedures, PUSCH transmission on PCell.

[0197] 4) If the terminal is configured to prioritize PRACH transmission on the SCell over semi-persistent and / or periodic SRS transmission, for example, if the UE is configured with the parameter priorscellprach-oversp-periodicsr;

[0198] 41) Perform aperiodic SRS or PRACH transmissions on serving cells other than PCell;

[0199] 42) Semi-persistent and / or periodic SRS transmission;

[0200] 5) If the terminal is not configured to prioritize PRACH transmissions on the Scell ​​over semi-persistent / periodic CSI transmissions; 51) SRS transmissions, non-periodic SRS have higher priority than semi-persistent and / or periodic SRS, or PRACH transmissions on the serving cell outside the PCell.

[0201] In another example, the principle for a terminal to reduce uplink transmission power can include the following order:

[0202] 1) PRACH transmission on PCell;

[0203] 2) PUCCH or PUSCH transmission on the primary FP or the primary FP assembly;

[0204] 3) Transmission of PUCCH or PUSCH with higher priority index;

[0205] 4) For PUCCH or PUSCH transmissions with the same priority index;

[0206] 41) PUCCH transmission with HARQ-ACK information, and / or SR, and / or LRR transmission, or PUSCH transmission with HARQ-ACK information with this priority index;

[0207] 42) PUCCH transmission with CSI or PUSCH transmission with CSI;

[0208] 43) PUSCH transmission without HARQ-ACK information or without CSI for Type-2 random access procedures, PUSCH transmission on PCell.

[0209] 5) If the terminal is configured to prioritize PRACH transmission on the SCell over semi-persistent and / or periodic SRS transmission, for example, if the parameter prioricellprach-oversp-periodicsr is configured;

[0210] 51) Perform aperiodic SRS or PRACH transmissions on serving cells other than PCell;

[0211] 52) Semi-persistent and / or periodic SRS transmission;

[0212] 6) If the terminal is not configured to prioritize PRACH transmissions on the Scell ​​over semi-persistent / periodic CSI transmissions; 61) SRS transmissions, non-periodic SRS have higher priority than semi-persistent and / or periodic SRS, or PRACH transmissions on the serving cell outside the PCell.

[0213] The above are just two possible examples. In practical applications, any combination of sequences can be selected as needed to determine the principle of reducing uplink transmission power of the terminal. This application does not impose any specific limitations on this.

[0214] The method provided in this application embodiment, for the first transmission timing of the first serving cell, if the total power of all first uplink transmissions in the target frequency domain unit exceeds the maximum transmission power corresponding to the target frequency domain unit, the terminal reduces the transmission power of the first uplink transmission according to a preset principle, so that the total power of all first uplink transmissions in the target frequency domain unit does not exceed the maximum transmission power corresponding to the target frequency domain unit. This provides a solution for reducing transmission power for a single cell that aggregates multiple discrete spectrums, which is beneficial to improving the effectiveness and flexibility of the transmission power control association function.

[0215] Figure 5 This diagram illustrates a flowchart of an uplink transmission power control method provided in an embodiment of this application. This method 500 can be executed by a network-side device. Figure 5 As shown, the method may include the following steps.

[0216] S502: The network-side device uses a first method to control the transmission power of the first uplink transmission for the first serving cell; and / or, the network-side device uses a second method to control the transmission power of the first uplink transmission for the first serving cell.

[0217] The first serving cell is configured to include at least one FP, the first mode is an uplink transmission-based control mode, and the second mode is a FP-based or FP-based combined control mode.

[0218] 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.

[0219] In this embodiment, a frequency field (FP) can be a set of continuous frequency domain resources. An FP can include any of the following: frequency band, carrier, subband, partial bandwidth, or frequency range. The frequency range can be predefined by a protocol or reported by the terminal to the network-side device.

[0220] In this embodiment of the application, a FP union includes at least one FP, which may include one FP or multiple FPs, and can be configured as needed, without specific limitations.

[0221] In this embodiment of the application, the first uplink transmission may include at least one of the following: PUCCH, PUSCH, SRS, PRACH.

[0222] In this embodiment of the application, the network-side device uses a first method to control the transmission power of the first uplink transmission for the first serving cell, which may include at least one of the following:

[0223] 1) The first power control parameters for the first uplink transmission transmitted per carrier per serving cell are the same for the network-side equipment.

[0224] This approach can encompass various scenarios. For example, in one scenario, the base station configures a first power control parameter for each carrier of each serving cell; in this case, the base station sets a single parameter. In another scenario, the base station uses a finer-grained configuration of the first power control parameter, configuring a separate first power control parameter for each FP of each carrier in each serving cell, and setting the same value for the first power control parameter for each FP; in this case, the base station sets multiple parameters with the same value.

[0225] 2) For at least one first uplink transmission transmitted on at least one FP of the first serving cell, the network-side equipment determines the transmission power of each first uplink transmission.

[0226] For example, multiple first uplink transmissions are transmitted on the six FPs of the first serving cell, and the base station determines the transmission power of each first uplink transmission within these six FPs.

[0227] 3) For at least one first uplink transmission of at least one FP joint uplink of the first serving cell, the network-side equipment determines the transmission power of each first uplink transmission.

[0228] For example, the three FPs of the first serving cell jointly transmit multiple first uplink transmissions, and the base station determines the transmission power of each first uplink transmission within these three FPs.

[0229] In this embodiment of the application, whether the scenario of transmitting at least one first uplink transmission on at least one FP or the scenario of transmitting at least one first uplink transmission jointly on at least one FP, the first power control parameter of each first uplink transmission can be the same or determined separately. The first power control parameter includes at least one of the following: the maximum transmission power of the terminal, the nominal power of the first uplink transmission, the path loss compensation factor, the RS used for downlink path loss estimation of the first uplink transmission, the power offset adjustment value, the TPC command, and the EPRE.

[0230] In this embodiment of the application, the network-side device uses a second method to control the transmission power of the first uplink transmission for the first serving cell, which may include at least one of the following:

[0231] 1) For the first uplink transmission transmitted on at least one FP of the first serving cell, the network-side equipment controls the transmission power of the first uplink transmission in each FP.

[0232] In this case, the network-side device can control the transmission power of the first uplink transmission within each FP to be the same or different, without being limited to any specific power level.

[0233] 2) For the first uplink transmission of at least one FP association in the first serving cell, the network-side equipment controls the transmission power of the first uplink transmission in each FP association.

[0234] In this case, the network-side device can control the transmission power of the first uplink transmission within each FP association to be the same or different, without being limited to any specific power level.

[0235] 3) For multiple first uplink transmissions within a FP of the first serving cell, the network-side equipment controls the transmission power of the multiple first uplink transmissions within a FP to be the same.

[0236] In this context, the network-side device controls the transmission power of multiple first uplink transmissions within a single FP to be the same, and the specific value is not limited.

[0237] 4) For multiple first uplink transmissions within a FP association of the first serving cell, the network-side equipment controls the transmission power of the multiple first uplink transmissions within a FP association to be the same.

[0238] In this context, the network-side device controls the transmission power of multiple first uplink transmissions within a single FP association to be the same, and the specific value is not limited.

[0239] In this embodiment of the application, the network-side device performs transmission power control on the first uplink transmission using a first method for the first serving cell; and the network-side device performs transmission power control on the first uplink transmission using a second method for the first serving cell, including at least one of the following:

[0240] 1) For multiple first uplink transmissions transmitted within a FP of the first serving cell, the network-side equipment controls the transmission power of each of the multiple first uplink transmissions within the FP.

[0241] 2) For multiple first uplink transmissions transmitted within a FP association of the first serving cell, the network-side equipment controls the transmission power of each of the multiple first uplink transmissions within the FP association;

[0242] 3) For multiple first uplink transmissions transmitted within multiple FPs of the first serving cell, the network-side equipment controls the transmission power of the multiple first uplink transmissions within the multiple FPs respectively, and the second power control parameters of the multiple first uplink transmissions within any one of the multiple FPs are the same.

[0243] 4) For multiple first uplink transmissions transmitted within multiple FP associations of the first serving cell, the network-side equipment controls the transmission power of the multiple first uplink transmissions within the multiple FP associations respectively, and the second power control parameters of the multiple first uplink transmissions within any FP association are the same.

[0244] The second power control parameter includes at least one of the following: the terminal's maximum transmission power, the nominal power corresponding to the first uplink transmission, the path loss compensation factor, and the RS used for downlink path loss estimation of the first uplink transmission.

[0245] In the embodiments of this application, when using the second method, or when using the first and second methods in combination, the above method may further include at least one of the following:

[0246] 1) Multiple first uplink transmissions within a single FP are of the same type;

[0247] 2) Multiple first uplink transmissions within an FP federation are of the same type;

[0248] 3) Multiple first uplink transmissions within a single FP are multiple uplink transmissions scheduled by a single DCI;

[0249] 4) Multiple first uplink transmissions within a single FP constitute multiple repetitions of a single uplink transmission;

[0250] 5) Multiple first uplink transmissions within an FP federation are multiple uplink transmissions scheduled by a DCI;

[0251] 6) Multiple first uplink transmissions within an FP union are multiple repetitions of a single uplink transmission.

[0252] In this embodiment of the application, the above method may further include at least one of the following:

[0253] 1) The network-side device configures, indicates or determines the first power control parameters of the first uplink transmission based on FP or FP joint configuration, wherein the first power control parameters include at least one of the following: terminal nominal maximum transmission power, nominal power of the first uplink transmission, path loss compensation factor, RS, EPRE, PSD for downlink path loss estimation of the first uplink transmission, MCS used for the first uplink transmission, and number of physical resource blocks (PRBs) for the first uplink transmission;

[0254] 2) Network-side devices configure, indicate, or determine the maximum transmission power of each FP based on the FP;

[0255] 3) Network-side devices configure, indicate, or determine the maximum transmission power of each FP alliance based on FP alliances;

[0256] 4) The network-side equipment, based on FP or FP combination, determines the power offset adjustment value according to the MCS used for the first uplink transmission;

[0257] 5) The first uplink transmission occurs on at least one FP, and the network-side device configures, instructs, or determines the TPC command according to any of the following: based on PUCCH, based on PUSCH, based on SRS, based on FP, based on FP combination, or based on the first serving cell.

[0258] When the network-side device configures, indicates, or determines a TPC command based on PUCCH, PUSCH, SRS, or the first serving cell, the number of bits of the TPC command included in the DCI that schedules the first uplink transmission can be represented as X1*M1. Here, X1 is the number of bits of the TPC command corresponding to one first uplink transmission, and M1 is the maximum number of first uplink transmissions that the DCI can schedule.

[0259] In this embodiment of the application, in the first mode, the number of RBs for the first uplink transmission is the number of RBs occupied by the first uplink transmission within the first serving cell. In the second mode, the number of RBs for the first uplink transmission is the number of RBs occupied by the first uplink transmission within a FP or a FP association.
