Those of ordinary skill in the art will know that with an evolution of a systemarchitecture and an occurrence of a new service scenario, the technical solutions provided by theembodiments of the present invention are still applicable to solve similar technical problems.

[0128] A method and apparatus for determining a power parameter provided by the presentinvention will be described in detail below with reference to the accompanying drawings.

[0129] FIG. 2 is a flowchart of a method for determining a power parameter provided byembodiments of the present invention, and the method is performed by a terminal device. As shown inFIG. 2, the method for determining the power parameter includes the following steps.

[0130] In S201, power control information of a physical uplink shared channel (PUSCH) isobtained.

[0131] It should be noted that, in the embodiments of the present invention, a state of the terminaldevice is not limited, for example, the terminal device may be in an idle state or an inactive state.

[0132] It can be understood that the terminal device may send data to the network device via thePUSCH, and a transmitting power of the PUSCH of the terminal device has a relatively large influence onthe reliability of the transmission of the PUSCH, and the power consumption of the terminal device.

[0133] In embodiments of the present invention, the terminal device may obtain the power controlinformation of the PUSCH.

[0134] Optionally, obtaining the power control information of the physical uplink shared channel(PUSCH) includes receiving the power control information of the PUSCH sent by a network device, orobtaining the power control information of the PUSCH according to a protocol agreement.

[0135] It can be understood that the network device may pre-configure the power controlinformation of the PUSCH for the terminal device, and send the configured power control information ofthe PUSCH to the terminal device. Correspondingly, the terminal device may receive the power controlinformation of the PUSCH sent by the network device. Alternatively, a protocol including a content of thepower control information of the PUSCH may be pre-agreed, and the terminal device may obtain thepower control information of the PUSCH according to the protocol agreement.

[0136] Optionally, the PUSCH is a PUSCH for a configure grant small data transmission(CG-SDT).

[0137] Optionally, the power control information includes at least one selected from: signalinformation configured to calculate a path loss compensation power value; configuration information ofan initial power component value; indication information of whether to allow a cumulative poweradjustment; and configuration information of a dynamic power added value.

[0138] Optionally, the signal information configured to calculate the path loss compensationpower value includes at least one selected from: a synchronous signal block (SSB); a reference signalassociated with the PUSCH; and a reference signal having a quasi-colocation (QCL) relationship with thePUSCH.

[0139] In an implementation manner, the signal information configured to calculate the path losscompensation power value includes the SSB. For example, the network device may configure the SSB forthe terminal device, and the SSB is configured to measure a path loss value, which may be configured tocalculate the path loss compensation power value.

[0140] In an implementation manner, the signal information configured to calculate the path losscompensation power value includes the reference signal associated with the PUSCH. It can be understoodthat different PUSCHs may be associated with different reference signals, and the reference signals maybe the SSBs. For example, as shown in FIG. 3, according to the protocol agreement, reference signalsSSB-0, SSB-1, SSB-2, and SSB-3 respectively associated with PUSCH-0, PUSCH-1, PUSCH-2, andPUSCH-3 are obtained. When the terminal device uses the PUSCH-1 to transmit data, the SSB-1associated with the PUSCH-1 is configured to measure the path loss value, and the path loss value isconfigured to calculate the path loss compensation power value.

[0141] In an implementation manner, the signal information configured to calculate the path losscompensation power value includes the reference signal having the quasi-colocation relationship with thePUSCH. It can be understood that the different PUSCHs correspond to different reference signals in thequasi-colocation relationship, and the reference signals may be the SSBs. For example, still referring toFIG. 3, reference signals SSB-0, SSB-1, SSB-2, and SSB-3 respectively having quasi-colocationrelationships with the PUSCH-0, the PUSCH-1, the PUSCH-2, and the PUSCH-3 are obtained. When theterminal device uses the PUSCH-1 to transmit data, the SSB-1 having the quasi-colocation relationshipwith the PUSCH-1 is configured to measure the path loss value, and the path loss value is configured tocalculate the path loss compensation power value.

[0142] Optionally, the configuration information of the initial power component value includes atleast one selected from: a nominal power component value configured by the network device; aterminal-specific power component value configured by the network device; an initial power componentvalue configured by the network device; a nominal power component value used in a previous randomaccess procedure; an initial power component value used in the previous random access procedure; anominal power component value used in a current random access procedure; and an initial powercomponent value used in the current random access procedure.

[0143] In an implementation manner, the terminal device receives a configuration signaling sentby the network device, and the configuration signaling is configured to configure at least one selectedfrom the nominal power component value, the terminal-specific power component value, and the initialpower component value, and thus the configuration information of the initial power component value isobtained according to the configuration signaling.

[0144] In an implementation manner, the terminal device has not received the configurationsignaling sent by the network device, and at this time the terminal device obtains at least one selectedfrom the nominal power component value used in the previous random access procedure, the initial powercomponent value used in the previous random access procedure, the nominal power component valueused in the current random access procedure, and the initial power component value used in the currentrandom access procedure as the configuration information of the initial power component value. It shouldbe noted that, in the embodiments of the present invention, the random access procedure is not limited,for example, it includes, but not limited to, a 2-step random access channel (RACH) procedure, and a4-step RACH procedure.

[0145] Optionally, the indication information of whether to allow the cumulative poweradjustment includes an indication bit, and the indication bit is configured to indicate that a cumulativepower adjustment value or an absolute power adjustment value is adopted. For example, a size of theindication bit may be 1 bit. When the indication bit adopts a value of 0, it indicates that the cumulativepower adjustment value is used, and when the indication bit adopts a value of 1, it indicates that theabsolute power adjustment value is used.

[0146] Optionally, the indication information of whether to allow the cumulative poweradjustment is indication information of allowing the cumulative power adjustment, and the indicationinformation of allowing the cumulative power adjustment is configured to indicate that the cumulativepower adjustment is configured for the PUSCH for the CG-SDT. In this way, the indication informationof allowing the cumulative power adjustment may be defined to be configured to indicate that thecumulative power adjustment is configured for the PUSCH for the CG-SDT.

[0147] Optionally, the configuration information of the dynamic power added value includes atleast one selected from: a power value added per time; and a maximum number of power additions.

[0148] In S202, a power adjustment value corresponding to a transmitting power of the PUSCH isdetermined according to the power control information.

[0149] In the embodiments of the present invention, the terminal device determines the poweradjustment value corresponding to the transmitting power of the PUSCH according to the power controlinformation, so as to adjust the transmitting power of the PUSCH according to the power adjustmentvalue corresponding to the transmitting power of the PUSCH.

[0150] It can be understood that the terminal device may calculate a power target value of thetransmitting power of the PUSCH according to the power control information and a related calculationformula of the transmitting power of the PUSCH, and determines the power adjustment valuecorresponding to the transmitting power of the PUSCH according to a difference value between a currentpower value of the transmitting power of the PUSCH and the power target value of the transmittingpower of the PUSCH. It should be noted that the related calculation formula of the transmitting power ofthe PUSCH may be set according to actual conditions, and is not limited herein.

[0151] According to the method for determining the power parameter provided by theembodiments of the present invention, the power control information of the PUSCH is obtained, and thepower adjustment value corresponding to the transmitting power of the PUSCH is determined accordingto the power control information. Therefore, the terminal device may determine the power adjustmentvalue corresponding to the transmitting power of the PUSCH according to the power control information,so that the transmitting power of the PUSCH may be adjusted according to the power adjustment valuecorresponding to the transmitting power of the PUSCH. The transmitting power of the PUSCH may beflexibly and accurately adjusted, which improves the reliability of the transmission on the PUSCH of theterminal device, and reduces the power consumption of the terminal device.

[0152] FIG. 4 is a flowchart of a method for determining a power parameter provided by furtherembodiments of the present invention, and the method is performed by a terminal device. As shown inFIG. 4, the method for determining the power parameter includes the following steps.

[0153] In S401, power control information of a physical uplink shared channel (PUSCH) isobtained.

[0154] In the embodiments of the present invention, step S401 may be implemented in any one ofthe embodiments of the present invention, which is not limited in the embodiments of the presentinvention, and will not be repeated here.

[0155] In S402, a power adjustment value corresponding to a transmitting power of the PUSCH isdetermined according to the power control information. The power adjustment value includes at least oneselected from: a path loss compensation power value; an initial power component value; a dynamic poweradjustment value, the dynamic power adjustment value including an accumulated power value or anabsolute power value; and a dynamic power added value.

[0156] In an implementation manner, the determined power adjustment value corresponding to thetransmitting power of the PUSCH includes the path loss compensation power value. At this time, thepower control information includes signal information configured to calculate the path loss compensationpower value, and the path loss compensation power value may be determined according to the signalinformation configured to calculate the path loss compensation power value.

[0157] Optionally, the path loss compensation power value may be determined according to a pathloss value measured by a reference signal corresponding to an identifier of a reference signal configuredto calculate the path loss compensation power value. It can be understood that the reference signalconfigured to calculate the path loss compensation power value is configured to measure the path lossvalue, and the path loss value is configured to calculate the path loss compensation power value. Anidentifier may be preset for the reference signal configured to calculate the path loss compensation powervalue, and thus different reference signals configured to calculate the path loss compensation powervalues can be distinguished from each other. The identifier of the reference signal configured to calculatethe path loss compensation power value includes at least one of: an SSB identifier; and a channel stateinformation reference signal (CSI-RS) identifier.

[0158] Optionally, determining the path loss compensation power value according to the path lossvalue measured by the reference signal includes determining a product value of the path loss valuemeasured by the reference signal and a path loss compensation factor as the path loss compensationpower value. The path loss compensation factor may be set according to actual conditions, and is notlimited herein.

[0159] In an implementation manner, the determined power adjustment value corresponding to thetransmitting power of the PUSCH includes the initial power component value. At this time, the powercontrol information includes the configuration information of the initial power component value, and theinitial power component value may be determined according to the configuration information of theinitial power component value. Optionally, the initial power component value included in theconfiguration information of the initial power component value may be determined as the initial powercomponent value. Alternatively, a sum value of the nominal power component value and theterminal-specific power component value included in the configuration information of the initial powercomponent value may be determined as the initial power component value.

[0160] In an implementation manner, the determined power adjustment value corresponding to thetransmitting power of the PUSCH includes the dynamic power adjustment value, and the dynamic poweradjustment value includes the accumulated power value or the absolute power value. At this time, thepower control information includes the indication information of whether to allow a cumulative poweradjustment, and the dynamic power adjustment value may be determined according to the indicationinformation of whether to allow the cumulative power adjustment.

[0161] Optionally, when the dynamic power adjustment value is determined to be the absolutepower value according to the indication information of whether to allow the cumulative power adjustment,the absolute power value may be determined according to a transmit power control (TPC) command of anetwork device. It can be understood that the network device may send the TPC command to the terminaldevice, and correspondingly, the terminal device may receive the TPC command and determine theabsolute power value according to the TPC command. For example, the TPC command may carry theindication information of the absolute power value, and the indication information includes, but is notlimited to, an adjustment value of the absolute power value, and the absolute power value may bedetermined according to the adjustment value of the absolute power value included in the TPC command.

[0162] Optionally, when the dynamic power adjustment value is determined to be the accumulatedpower value according to the indication information of whether to allow the cumulative power adjustment,the accumulated power value is determined according to a sum value of a dynamic power adjustmentvalue of a previous transmission and an absolute power value of a current transmission.

[0163] Optionally, when a first preset condition is satisfied, a rollback process is performed on thedynamic power adjustment value. Performing the rollback process on the dynamic power adjustmentvalue refers to adjusting a dynamic power adjustment value of the current transmission to the dynamicpower adjustment value of the previous transmission. The first preset condition may be set according tothe actual conditions. For example, the first preset condition includes at least one selected from: receivinga connection release message; receiving a connection refused message; receiving indication informationof entering an idle state; and receiving feedback information of successfully receiving data sent by thenetwork device. Therefore, the method may perform the rollback process on the dynamic poweradjustment value when the first preset condition is satisfied.

[0164] Optionally, when the first preset condition is satisfied, an initialization process isperformed on the dynamic power adjustment value. Performing the initialization process on the dynamicpower adjustment value refers to setting the dynamic power adjustment value as an initial value. Theinitial value may be set according to the actual conditions, for example, may be set to 0. Therefore, themethod may perform the initialization process on the dynamic power adjustment value when the firstpreset condition is satisfied.

[0165] For example, as shown in FIG. 5, a terminal device sends uplink data to a network devicevia PUSCH-1 at a moment t1, and starts a feedback receiving timer (such as a feedback timer), and theterminal device receives retransmission scheduling downlink control information (DCI) signaling fromthe network device for the PUSCH-1 at a moment t2. The DCI signaling carries indication information ofa dynamic power adjustment value, and the terminal device determines the dynamic power adjustmentvalue according to the indication information of the dynamic power adjustment value included in the DCIsignaling, adopts the determined dynamic power adjustment value to retransmit the data (which has beentransmitted via the PUSCH-1) at a moment t3, and adopts the determined dynamic power adjustmentvalue to send uplink data to the network device via PUSCH-5 at a moment t4. At a moment t5, theterminal device receives a connection release message of a radio resource control (RRC) signaling, andperforms a rollback process or an initialization process on the dynamic power adjustment value.

[0166] In an implementation manner, the determined power adjustment value corresponding to thetransmitting power of the PUSCH includes the dynamic power added value. At this time, the powercontrol information includes the configuration information of the dynamic power added value, and thedynamic power added value may be determined according to the configuration information of thedynamic power added value.

[0167] Optionally, the dynamic power added value is determined according to a product of apower value added per time and a number of power additions in the configuration information of thedynamic power added value.

[0168] Optionally, when a second preset condition is satisfied, the dynamic power added value isdetermined. Therefore, the method may only determine the dynamic power added value when the secondpreset condition is satisfied, and at this time, the power adjustment value corresponding to thetransmitting power of the PUSCH includes the dynamic power added value. Otherwise, when the secondpreset condition is not satisfied, the dynamic power added value is not determined, and at this time, thepower adjustment value corresponding to the transmitting power of the PUSCH does not include thedynamic power added value.

[0169] The second preset condition may be set according to actual conditions, for example, thesecond preset condition includes retransmitting transmitted data.

[0170] Optionally, retransmitting the transmitted data includes at least one selected from:retransmitting the transmitted data on a PUSCH with a same configure grant (CG) resource as a previoustransmission; retransmitting the transmitted data by using a same hybrid automatic repeat request (HARQ)process as the previous transmission; and retransmitting the transmitted data by using the same HARQprocess as the previous transmission on the PUSCH with the same CG resource as the previoustransmission.

[0171] Optionally, when a third preset condition is satisfied, a rollback process is performed onthe dynamic power added value. Performing the rollback process on the dynamic power added valuerefers to adjusting a dynamic power added value of a current transmission to a dynamic power addedvalue of a previous transmission. The third preset condition includes at least one selected from: receivinga connection release message; receiving a connection refused message; receiving indication informationof entering an idle state; and receiving feedback information of successfully receiving data sent by thenetwork device. Therefore, the method may perform the rollback process on the dynamic power addedvalue when the third preset condition is satisfied.

[0172] Optionally, when the third preset condition is satisfied, an initialization process isperformed on the dynamic power added value. Performing the initialization process on the dynamicpower added value refers to setting the dynamic power added value as an initial value. The initial valuemay be set according to the actual conditions, for example, may be set to 0. Therefore, the method mayperform the initialization process on the dynamic power added value when the third preset condition issatisfied.

[0173] According to the method for determining the power parameter in the embodiments of thepresent invention, the power control information of the PUSCH is obtained, and the power adjustmentvalue corresponding to the transmitting power of the PUSCH is determined according to the powercontrol information. The power adjustment value includes at least one selected from: the path losscompensation power value; the initial power component value; the dynamic power adjustment value, thedynamic power adjustment value including the accumulated power value or the absolute power value; andthe dynamic power added value. Therefore, the terminal device may determine the power adjustmentvalue corresponding to the transmitting power of the PUSCH according to the power control information,so that the transmitting power of the PUSCH may be adjusted according to the power adjustment valuecorresponding to the transmitting power of the PUSCH. The transmitting power of the PUSCH may beflexibly and accurately adjusted, which improves the reliability of the transmission on the PUSCH of theterminal device, and reduces the power consumption of the terminal device.

[0174] FIG. 6 is a flowchart of a method for determining a power parameter provided byembodiments of the present invention, which is performed by a network device. As shown in FIG. 6, themethod for determining the power parameter includes the following step.

[0175] In S601, power control information of a physical uplink shared channel (PUSCH) is sentto a terminal device, in which the power control information is configured to determine a poweradjustment value corresponding to a transmitting power of the PUSCH.

[0181] In an implementation manner, the signal information configured to calculate the path losscompensation power value includes the reference signal associated with the PUSCH. It can be understoodthat different PUSCHs may be associated with different reference signals, and the reference signals maybe the SSBs. For example, as shown in FIG. 3, reference signals SSB-0, SSB-1, SSB-2, and SSB-3 arerespectively associated with PUSCH-0, PUSCH-1, PUSCH-2, and PUSCH-3. When the terminal deviceuses the PUSCH-1 to transmit data, the SSB-1 associated with the PUSCH-1 is configured to measure thepath loss value, and the path loss value may be configured to calculate the path loss compensation powervalue.

[0182] In an implementation manner, the signal information configured to calculate the path losscompensation power value includes the reference signal having the quasi-colocation relationship with thePUSCH. It can be understood that the different PUSCHs correspond to different reference signals in thequasi-colocation relationship, and the reference signals may be the SSBs. For example, still referring toFIG. 3, reference signals SSB-0, SSB-1, SSB-2, and SSB-3 respectively have quasi-colocationrelationships with the PUSCH-0, the PUSCH-1, the PUSCH-2, and the PUSCH-3. When the terminaldevice uses the PUSCH-1 to send, the SSB-1 having the quasi-colocation relationship with the PUSCH-1is configured to measure the path loss value, and the path loss value is configured to calculate the pathloss compensation power value.

[0183] Optionally, the configuration information of the initial power component value includes atleast one selected from: a configured nominal power component value; a configured terminal-specificpower component value; a configured initial power component value; a nominal power component valueused in a previous random access procedure; an initial power component value used in the previousrandom access procedure; a nominal power component value used in a current random access procedure;and an initial power component value used in the current random access procedure.

[0184] In an implementation manner, the network device sends a configuration signaling to theterminal device, and the configuration signaling is configured to configure at least one selected from thenominal power component value, the terminal-specific power component value, and the initial powercomponent value, and thus the configuration signaling is configured to obtain the configurationinformation of the initial power component value.

[0185] In an implementation manner, the network device does not send the configurationsignaling to the terminal device, and at this time the terminal device obtains at least one selected from thenominal power component value used in the previous random access procedure, the initial powercomponent value used in the previous random access procedure, the nominal power component valueused in the current random access procedure, and the initial power component value used in the currentrandom access procedure as the configuration information of the initial power component value. It shouldbe noted that, in the embodiments of the present invention, the random access procedure is not limited,for example, it includes, but not limited to, a 2-step random access channel (RACH), and a 4-step RACH.

[0186] Optionally, the indication information of whether to allow the cumulative poweradjustment includes an indication bit, and the indication bit is configured to indicate that a cumulativepower adjustment value or an absolute power adjustment value is adopted. For example, a size of theindication bit may be 1 bit. When the indication bit adopts a value of 0, it indicates that the cumulativepower adjustment value is used, and when the indication bit adopts a value of 1, it indicates that theabsolute power adjustment value is used.

[0187] Optionally, the indication information of whether to allow the cumulative poweradjustment is indication information of allowing the cumulative power adjustment, and the indicationinformation of allowing the cumulative power adjustment is configured to indicate that the cumulativepower adjustment is configured for the PUSCH for the configure grant small data transmission (CG-SDT).In this way, the indication information of allowing the cumulative power adjustment may be defined to beconfigured to indicate that the cumulative power adjustment is configured for the PUSCH for theCG-SDT.

[0188] Optionally, the configuration information of the dynamic power added value includes atleast one selected from: a power value added per time; and a maximum number of power additions.

[0189] Optionally, the determined power adjustment value corresponding to the transmittingpower of the PUSCH includes at least one selected from: a path loss compensation power value; an initialpower component value; a dynamic power adjustment value, the dynamic power adjustment valueincluding an accumulated power value or an absolute power value; and a dynamic power added value.

[0190] In an implementation manner, the determined power adjustment value corresponding to thetransmitting power of the PUSCH includes the path loss compensation power value. At this time, thepower control information includes the signal information configured to calculate the path losscompensation power value, and the path loss compensation power value may be determined according tothe signal information configured to calculate the path loss compensation power value.

[0191] Optionally, the path loss compensation power value may be determined according to a pathloss value measured by a reference signal corresponding to an identifier of a reference signal configuredto calculate the path loss compensation power value. It can be understood that the reference signalconfigured to calculate the path loss compensation power value is configured to measure the path lossvalue, and the path loss value is configured to calculate the path loss compensation power value. Anidentifier may be preset for the reference signal configured to calculate the path loss compensation powervalue, and thus different reference signals configured to calculate the path loss compensation powervalues can be distinguished from each other. The identifier of the reference signal configured to calculatethe path loss compensation power value includes at least one of: an SSB identifier; and a channel stateinformation reference signal (CSI-RS) identifier.

[0192] Optionally, the path loss compensation power value is determined according to a productvalue of the path loss value (measured by the reference signal corresponding to the identifier of thereference signal configured to calculate the path loss compensation power value) and a path losscompensation factor. The path loss compensation factor may be set according to actual conditions, and isnot limited herein.

At this time, the powercontrol information includes the configuration information of the initial power component value, and theinitial power component value may be determined according to the configuration information of theinitial power component value. Optionally, the initial power component value is determined according tothe initial power component value included in the configuration information of the initial powercomponent value. Alternatively, the initial power component value may be determined according to a sumvalue of the nominal power component value and the terminal-specific power component value includedin the configuration information of the initial power component value.

[0194] In an implementation manner, the determined power adjustment value corresponding to thetransmitting power of the PUSCH includes the dynamic power adjustment value, and the dynamic poweradjustment value includes the accumulated power value or the absolute power value. At this time, thepower control information includes the indication information of whether to allow a cumulative poweradjustment, and the dynamic power adjustment value may be determined according to the indicationinformation of whether to allow the cumulative power adjustment.

[0195] Optionally, when the dynamic power adjustment value is the absolute power value, theabsolute power value is determined according to a transmit power control (TPC) command of a networkdevice. It can be understood that the network device may send the TPC command to the terminal device,and the TPC command is configured to determine the absolute power value. For example, the TPCcommand may carry the indication information of the absolute power value, and the indicationinformation includes, but is not limited to, an adjustment value of the absolute power value, and theabsolute power value may be determined according to the adjustment value of the absolute power valueincluded in the TPC command.

[0196] Optionally, when the dynamic power adjustment value is the accumulated power value, theaccumulated power value may be determined according to a sum value of a dynamic power adjustmentvalue of a previous transmission and an absolute power value of a current transmission.

[0197] Optionally, the terminal device satisfies a first preset condition, and the dynamic poweradjustment value is a value after performing a rollback process. The dynamic power adjustment valuebeing the value after performing the rollback process refers to that a dynamic power adjustment value of acurrent transmission is a dynamic power adjustment value of the previous transmission. The first presetcondition may be set according to the actual conditions. For example, the first preset condition includes atleast one selected from: receiving a connection release message; receiving a connection refused message;receiving indication information of entering an idle state; and receiving feedback information ofsuccessfully receiving data sent by the network device. Therefore, the dynamic power adjustment value isthe value after performing the rollback process when the terminal device satisfies the first presetcondition.

[0198] Optionally, the terminal device satisfies the first preset condition, and the dynamic poweradjustment value is a value after performing an initialization process. The dynamic power adjustmentvalue being the value after performing the initialization process refers to that a dynamic power adjustmentvalue of a current transmission is an initial value. The initial value may be set according to the actualconditions, for example, may be set to 0. Therefore, the dynamic power adjustment value is the valueafter performing the initialization process when the terminal device satisfies the first preset condition.

[0199] In an implementation manner, the determined power adjustment value corresponding to thetransmitting power of the PUSCH includes the dynamic power added value. At this time, the powercontrol information includes the configuration information of the dynamic power added value, and thedynamic power added value may be determined according to the configuration information of thedynamic power added value.

[0200] Optionally, the dynamic power added value is determined according to a product of thepower value added per time and the number of the power additions.

[0201] Optionally, the dynamic power added value is determined when the terminal devicesatisfies a second preset condition. Therefore, the method may only determine the dynamic power addedvalue when the terminal device satisfies the second preset condition, and at this time, the poweradjustment value corresponding to the transmitting power of the PUSCH includes the dynamic poweradded value. Otherwise, when the second preset condition is not satisfied, the dynamic power added valueis not determined, and at this time, the power adjustment value corresponding to the transmitting power ofthe PUSCH does not include the dynamic power added value.

[0202] The second preset condition may be set according to the actual conditions, for example,the second preset condition includes retransmitting transmitted data.

[0203] Optionally, retransmitting the transmitted data includes at least one selected from:retransmitting the transmitted data on a PUSCH with a same configure grant (CG) resource as a previoustransmission; retransmitting the transmitted data by using a same hybrid automatic repeat request (HARQ)process as the previous transmission; and retransmitting the transmitted data by using the same HARQprocess as the previous transmission on the PUSCH with the same CG resource as the previoustransmission.

[0204] Optionally, when the terminal device satisfies a third preset condition, the dynamic poweradded value is a value after performing the rollback process. The dynamic power added value being thevalue after performing the rollback process refers to that a dynamic power added value of a currenttransmission is a dynamic power added value of a previous transmission. The third preset condition maybe set according to the actual conditions, for example, the third preset condition includes at least oneselected from: receiving a connection release message; receiving a connection refused message; receivingindication information of entering an idle state; and receiving feedback information of successfullyreceiving the data sent by the network device. Therefore, the dynamic power added value is the valueafter performing the rollback process when the terminal device satisfies the third preset condition.

[0205] Optionally, when the terminal device satisfies the third preset condition, the dynamicpower added value is a value after performing the initialization process. The dynamic power added valuebeing the value after performing the initialization process refers to that a dynamic power added value of acurrent transmission is an initial value. The initial value may be set according to the actual conditions, forexample, may be set to 0.
