[0122] A terminal device can transmit data to a network device via a physical uplink shared channel (PUSCH), and the transmission power of the terminal device on the PUSCH significantly affects the transmission reliability of the PUSCH and the energy consumption of the terminal device.

[0123] In an embodiment of the present application, a terminal device can obtain power control information on a PUSCH.

[0124] Optionally, obtaining power control information on a physical uplink shared channel (PUSCH) may include receiving power control information on a PUSCH transmitted from a network device, or obtaining power control information on a PUSCH based on a protocol convention.

[0125] In addition, the network device can set the power control information in the PUSCH in the terminal device in advance, and transmit the set power control information in the PUSCH to the terminal device, and the terminal device can receive the power control information in the PUSCH transmitted from the network device accordingly. Alternatively, a protocol including the content of the power control information in the PUSCH is predefined, and the terminal device can obtain the power control information in the PUSCH based on the protocol definition.

[0126] Optionally, the PUSCH can be used for configured grant small data transmission. d The PUSCH is a PUSCH for Grant Small Data Transmission (CG-SDT).

[0127] Optionally, the power control information includes at least one of signal information for calculating a path loss compensation power value, setting information for an initial power component value, instruction information for whether to allow cumulative power adjustment, and setting information for a dynamic power add-on value.

[0128] Optionally, the signal information for calculating the path loss compensation power value includes at least one of a Synchronous Signal Block (SSB), a reference signal related to the PUSCH, and a reference signal having a Quasi-CoLocation (QCL) relationship with the PUSCH.

[0129] In one implementation, the signal information for calculating the path loss compensation power value may include an SSB, e.g., the network device may configure an SSB in the terminal device, the SSB may be used to measure the path loss value, and the path loss value may be used to calculate the path loss compensation power value.

[0130] In one implementation, the signal information for calculating the path loss power compensation value may include a reference signal associated with the PUSCH. It should be noted that different PUSCHs may be associated with different reference signals, and the reference signal may be an SSB. For example, as shown in FIG. 3, according to the protocol rules, reference signals SSB-0, SSB-1, SSB-2, and SSB-3 are obtained that are associated with PUSCH-0, PUSCH-1, PUSCH-2, and PUSCH-3, respectively, and when the terminal device adopts PUSCH-1 to transmit, the SSB-1 associated with PUSCH-1 is used to measure the path loss value, and the path loss value can be used to calculate the path loss compensation power value.

[0131] In one implementation, the signal information for calculating the path loss power compensation value may include a reference signal having a quasi-collocated relationship with PUSCH. Note that the reference signals having a quasi-collocated relationship corresponding to different PUSCHs are different, and the reference signal may be an SSB. For example, still taking FIG. 3 as an example, obtain reference signals SSB-0, SSB-1, SSB-2, and SSB-3 having a quasi-collocated relationship with PUSCH-0, PUSCH-1, PUSCH-2, and PUSCH-3, respectively, and when the terminal device adopts PUSCH-1 to transmit, the SSB-1 having a quasi-collocated relationship with PUSCH-1 is used to measure the path loss value, and the path loss value can be used to calculate the path loss compensation power value.

[0132] Optionally, the setting information of the initial power component value includes at least one of a nominal power component value set by the network device, a terminal-specific power component value set by the network device, an initial power component value set by the network device, a nominal power component value used in a previous random access process, an initial power component value used in a previous random access process, a nominal power component value used in a current random access process, and an initial power component value used in the current random access process.

[0133] In one implementation, the terminal device can receive configuration signaling transmitted from the network device, and the configuration signaling is used to set at least one of a nominal power component value, a terminal-specific power component value, and an initial power component value, thereby obtaining configuration information for the initial power component value based on the configuration signaling.

[0134] In one implementation, the terminal device does not receive the configuration signaling sent from the network device, and at this time, the terminal device can obtain at least one of the nominal power component value used in the previous random access process, the initial power component value used in the previous random access process, the nominal power component value used in the current random access process, and the initial power component value used in the current random access process as the configuration information of the initial power component value. Note that, in the embodiment of the present application, the random access process is not limited to much, for example, includes, but is not limited to, 2-step Random Access Channel (RACH), 4-step RACH, etc.

[0135] Alternatively, the indication information of whether to allow the cumulative power adjustment may include an indication bit for instructing the adoption of the cumulative power adjustment value or the absolute power adjustment value. For example, the size of the indication bit may be 1 bit, and when the value of the indication bit is 0, it indicates the adoption of the cumulative power adjustment value, and when the value of the indication bit is 1, it indicates the adoption of the absolute power adjustment value.

[0136] Alternatively, the instruction information on whether to permit cumulative power adjustment is instruction information for permitting cumulative power adjustment, and the instruction information for permitting cumulative power adjustment is an instruction information for permitting cumulative power adjustment when the cumulative power adjustment is a configured grant small data transmission (Configure dIn this case, the accumulated power adjustment indication information indicates that the accumulated power adjustment is to be used for the PUSCH of the CG-SDT.

[0137] Optionally, the setting information of the dynamic power addition value includes at least one of a power value added each time and a maximum number of times of power addition.

[0138] In step S202, a power adjustment value corresponding to the transmission power in the PUSCH is determined based on the power control information.

[0139] In an embodiment of the present application, the terminal device can determine a power adjustment value corresponding to the transmission power in the PUSCH based on the power control information, and adjust the transmission power in the PUSCH based on the power adjustment value corresponding to the transmission power in the PUSCH.

[0140] In addition, the terminal device can calculate the power target value of the transmission power of the PUSCH according to the power control information and the calculation formula related to the transmission power of the PUSCH, and further determine the power adjustment value corresponding to the transmission power of the PUSCH according to the difference between the current power value of the transmission power of the PUSCH and the power target value of the transmission power of the PUSCH. In addition, the calculation formula related to the transmission power of the PUSCH can be set according to the actual situation, but is not limited here.

[0141] According to the method for determining power parameters according to the embodiment of the present application, power control information on a physical uplink shared channel (PUSCH) is obtained, and a power adjustment value corresponding to the transmission power on the PUSCH is determined according to the power control information, so that the terminal device determines a power adjustment value corresponding to the transmission power on the PUSCH according to the power control information, and adjusts the transmission power on the PUSCH according to the power adjustment value corresponding to the transmission power on the PUSCH, thereby enabling the terminal device to flexibly and accurately adjust the transmission power on the PUSCH, which is helpful in ensuring the transmission reliability of the terminal device on the PUSCH and saving the energy consumption of the terminal device.

[0142] FIG. 4 is a schematic flowchart of a method for determining another power parameter provided by an embodiment of the present application, which is performed by a terminal device. As shown in FIG. 4, the method for determining a power parameter includes the following steps S401 to S402.

[0143] In step S401, power control information on a physical uplink shared channel (PUSCH) is obtained.

[0144] In the embodiments of the present application, step S401 can be implemented using any of the methods in each embodiment of the present application, and the embodiments of the present application are not limited thereto, and no description will be given here.

[0145] In step S402, determine a power adjustment value corresponding to the transmission power of the PUSCH based on the power control information, where the power adjustment value includes at least one of a path loss compensation power value, an initial power component value, a dynamic power adjustment value including an accumulated power value or an absolute power value, and a dynamic power addition value.

[0146] In one implementation, it is determined that a power adjustment value corresponding to a transmission power on a PUSCH includes a path loss compensation value, where the power control information includes signal information for calculating the path loss compensation power value, and the path loss compensation value can be determined based on the signal information for calculating the path loss compensation power value.

[0147] Alternatively, the path loss compensation power value may be determined based on a path loss value measured in a reference signal corresponding to an identifier of the reference signal for calculating the path loss compensation power value. The reference signal for calculating the path loss compensation power value is used to measure the path loss value, and the path loss value can be used to calculate the path loss compensation power value. Different reference signals for calculating the path loss compensation power value may be distinguished by presetting an identifier in the reference signal for calculating the path loss compensation power value. Here, the identifier of the reference signal for calculating the path loss compensation power value includes at least one of an SSB identifier and a Channel State Information Reference Signal (CSI-RS) identifier.

[0148] Optionally, determining a path loss compensation power value based on a path loss value measured by a reference signal may include determining a product value of a path loss value measured by a reference signal and a path loss compensation factor as a path loss compensation power value, where the path loss compensation factor may be set according to an actual situation and is not particularly limited herein.

[0149] In one implementation, it is determined that a power adjustment value corresponding to a transmission power in the PUSCH includes an initial power component value. At this time, the power control information includes setting information of the initial power component value, and the initial power component value can be determined based on the setting information of the initial power component value. Alternatively, the initial power component value can be determined as the initial power component value by using the initial power component value setting information. Alternatively, the sum of the nominal power component value and the terminal-specific power component value in the setting information of the initial power component value can be determined as the initial power component value.

[0150] In one implementation, it is determined that the power adjustment value corresponding to the transmission power in the PUSCH includes a dynamic power adjustment value including an accumulated power value or an absolute power value, where the power control information includes an indication of whether the accumulated power adjustment is allowed, and the dynamic power adjustment value can be determined based on the indication of whether the accumulated power adjustment is allowed.

[0151] Alternatively, if it is determined that the dynamic power adjustment value is an absolute power value based on the indication information of whether to allow the cumulative power adjustment, the absolute power value may be determined based on a transmit power control (TPC) command of the network device. Note that the network device may send a TPC command to the terminal device, and in response, the terminal device may receive the TPC command and determine the absolute power value based on the TPC command. For example, the TPC command may carry indication information of the absolute power value, and the indication information may include, but is not limited to, an adjustment value of the absolute power value, and the absolute power value may be determined based on the adjustment value of the absolute power value in the TPC command.

[0152] Alternatively, if the dynamic power adjustment value is determined to be a cumulative power value based on the instruction information on whether or not cumulative power adjustment is allowed, the cumulative power value can be determined based on the sum of the previously transmitted dynamic power adjustment value and the currently transmitted absolute power value.

[0153] Optionally, if a first preset condition is met, a rollback process may be performed on the dynamic power adjustment value. Here, performing the rollback process on the dynamic power adjustment value means adjusting the currently transmitted dynamic power adjustment value to the previously transmitted dynamic power adjustment value. Here, the first preset condition may be set based on an actual situation, and for example, the first preset condition may include at least one of: a disconnection message is received; a connection rejection message is received; instruction information to enter an idle state is received; and feedback information transmitted from a network device indicating successful reception of data is received. Thus, the method may perform a rollback process on the dynamic power adjustment value if the first preset condition is met.

[0154] Optionally, an initialization process can be performed on the dynamic power adjustment value when the first preset condition is met. Here, the initialization process on the dynamic power adjustment value means setting the dynamic power adjustment value to an initial value. Here, the initial value can be set based on an actual situation, for example, can be set to 0. Thus, the method can perform an initialization process on the dynamic power adjustment value when the first preset condition is met.

[0155] For example, as shown in FIG. 5, at time t1, the terminal device transmits uplink data to the network device via PUSCH-1 and starts a feedback reception timer (e.g., FeedbackTimer); at time t2, the network device receives retransmission scheduling downlink control information (DCI) signaling for PUSCH-1, where the DCI signaling carries indication information of a dynamic power adjustment value, and the terminal device can determine a dynamic power adjustment value based on the indication information of the dynamic power adjustment value in the DCI signaling; at time t3, the terminal device retransmits data transmitted on PUSCH-1 by adopting the determined dynamic power adjustment value; at time t4, the terminal device transmits uplink data to the network device via PUSCH-5 by adopting the determined dynamic power adjustment value; and at time t5, the terminal device receives a Radio Resource Control (RRC) signaling disconnection message and performs a rollback process or an initialization process on the dynamic power adjustment value.

[0156] In one implementation, it is determined that the power adjustment value corresponding to the transmission power on the PUSCH includes a dynamic power addition value, and the power control information includes setting information of the dynamic power addition value, and the dynamic power addition value can be determined based on the setting information of the dynamic power addition value.

[0157] Alternatively, the dynamic power addition value can be determined based on the product of the power value added each time and the number of times power is added, in the setting information of the dynamic power addition value.

[0158] Optionally, a dynamic power charge-up value is determined if a second preset condition is met, whereby the method can determine a dynamic power charge-up value if the second preset condition is met, where the power adjustment value corresponding to the transmission power in the PUSCH includes the dynamic power charge-up value, and conversely, not determine a dynamic power charge-up value if the second preset condition is not met, where the power adjustment value corresponding to the transmission power in the PUSCH does not include the dynamic power charge-up value.

[0159] Here, the second preset condition can be set based on an actual situation, for example, the second preset condition includes retransmitting the transmitted data.

[0160] Optionally, retransmitting a transmission may be done using the same configured grant as the previous transmission. d retransmitting the transmitted data on a PUSCH of the same CG resources as the previous transmission using the same Hybrid Automatic Repeat ReQuest (HARQ) process as the previous transmission; and retransmitting the transmitted data on a PUSCH of the same CG resources as the previous transmission using the same HARQ process as the previous transmission.

[0161] Alternatively, a rollback process may be performed on the dynamic power charge value when a third preset condition is satisfied. Here, performing the rollback process on the dynamic power charge value means adjusting the currently transmitted dynamic power charge value to the previously transmitted dynamic power charge value. Here, the third preset condition includes at least one of receiving a disconnection message, receiving a connection rejection message, receiving an instruction to enter an idle state, and receiving feedback information transmitted from a network device indicating successful reception of data. Thus, the method may perform a rollback process on the dynamic power charge value when the third preset condition is satisfied.

[0162] Optionally, the dynamic power add-on value may be initialized when a third preset condition is met. Here, the initialization of the dynamic power add-on value means setting the dynamic power add-on value to an initial value. Here, the initial value may be set based on an actual situation, for example, may be set to 0. Thus, the method may be configured to initialize the dynamic power add-on value when a third preset condition is met.

[0163] According to the method for determining power parameters according to the embodiment of the present application, power control information on a physical uplink shared channel (PUSCH) is obtained, and a power adjustment value corresponding to the transmission power on the PUSCH is determined according to the power control information, where the power adjustment value includes at least one of a path loss compensation power value, an initial power component value, a dynamic power adjustment value including an accumulated power value or an absolute power value, and a dynamic power supplement value. Thus, the terminal device determines a power adjustment value corresponding to the transmission power on the PUSCH according to the power control information, and adjusts the transmission power on the PUSCH according to the power adjustment value corresponding to the transmission power on the PUSCH, so that the transmission power on the PUSCH can be flexibly and accurately adjusted, which is helpful to ensure the transmission reliability of the terminal device on the PUSCH and save the energy consumption of the terminal device.

[0171] In one implementation, the signal information for calculating the path loss power compensation value may include a reference signal associated with the PUSCH. It should be noted that different PUSCHs may be associated with different reference signals, and the reference signal may be an SSB. For example, as shown in Figure 3, there are reference signals SSB-0, SSB-1, SSB-2, and SSB-3 associated with PUSCH-0, PUSCH-1, PUSCH-2, and PUSCH-3, respectively, and when the terminal device employs PUSCH-1 to transmit, the SSB-1 associated with PUSCH-1 is used to measure the path loss value, and the path loss value can be used to calculate the path loss compensation power value.

[0172] In one implementation, the signal information for calculating the path loss power compensation value may include a reference signal having a quasi-collocated relationship with the PUSCH. Note that the reference signals having a quasi-collocated relationship corresponding to different PUSCHs are different, and the reference signal may be an SSB. For example, still taking FIG. 3 as an example, there are reference signals SSB-0, SSB-1, SSB-2, and SSB-3 having a quasi-collocated relationship with PUSCH-0, PUSCH-1, PUSCH-2, and PUSCH-3, respectively, and when the terminal device adopts PUSCH-1 to transmit, the SSB-1 having a quasi-collocated relationship with PUSCH-1 is used to measure the path loss value, and the path loss value can be used to calculate the path loss compensation power value.

[0173] Optionally, the setting information of the initial power component value includes at least one of a set nominal power component value, a set terminal-specific power component value, a set initial power component value, a nominal power component value used in a previous random access process, an initial power component value used in a previous random access process, a nominal power component value used in a current random access process, and an initial power component value used in the current random access process.

[0174] In one implementation, the network device can send configuration signaling to the terminal device, where the configuration signaling is used to configure at least one of a nominal power component value, a terminal-specific power component value, and an initial power component value, whereby the configuration signaling is used to obtain configuration information for the initial power component value.

[0175] In one implementation, the network device does not send configuration signaling to the terminal device, and at this time the terminal device can obtain at least one of the nominal power component value used in the previous random access process, the initial power component value used in the previous random access process, the nominal power component value used in the current random access process, and the initial power component value used in the current random access process as the configuration information of the initial power component value. Note that, in the embodiment of the present application, the random access process is not particularly limited, and includes, for example, 2-step Random Access Channel (RACH), 4-step RACH, etc., but is not limited thereto.

[0176] Alternatively, the indication information of whether to allow the cumulative power adjustment may include an indication bit for instructing the adoption of the cumulative power adjustment value or the absolute power adjustment value. For example, the size of the indication bit may be 1 bit, and when the value of the indication bit is 0, it indicates the adoption of the cumulative power adjustment value, and when the value of the indication bit is 1, it indicates the adoption of the absolute power adjustment value.

[0177] Alternatively, the instruction information on whether to permit cumulative power adjustment is instruction information for permitting cumulative power adjustment, and the instruction information for permitting cumulative power adjustment is an instruction information for permitting cumulative power adjustment when the cumulative power adjustment is a configured grant small data transmission (Configure dIn this case, the accumulated power adjustment indication information indicates that the accumulated power adjustment is to be used for the PUSCH of the CG-SDT.

[0178] Optionally, the setting information of the dynamic power addition value includes at least one of a power value added each time and a maximum number of times of power addition.

[0179] Optionally, determine that the power adjustment value corresponding to the transmission power on the PUSCH includes at least one of a path loss compensation power value, an initial power component value, a dynamic power adjustment value including an accumulated power value or an absolute power value, and a dynamic power addition value.

[0180] In one implementation, it is determined that a power adjustment value corresponding to a transmission power on the PUSCH comprises a pathloss power compensation value, where the power control information comprises signal information for calculating the pathloss compensation power value, and the pathloss power compensation value is determined based on the signal information for calculating the pathloss compensation power value.

[0181] Optionally, the path loss compensation power value is determined based on a path loss value measured by a reference signal corresponding to an identifier of the reference signal for calculating the path loss compensation power value. Note that the reference signal for calculating the path loss compensation power value is used to measure the path loss value, and the path loss value can be used to calculate the path loss compensation power value. By presetting an identifier to the reference signal for calculating the path loss compensation power value, different reference signals for calculating the path loss compensation power value can be distinguished. Here, the identifier of the reference signal for calculating the path loss compensation power value includes at least one of an SSB identifier and a Channel State Information Reference Signal (CSI-RS) identifier.

[0182] Optionally, the path loss compensation power value is determined based on a product value of a path loss value measured in a reference signal corresponding to an identifier of the reference signal for calculating the path loss compensation power value and a path loss compensation factor, where the path loss compensation factor can be set according to an actual situation and is not particularly limited herein.

[0183] In one implementation, it is determined that a power adjustment value corresponding to a transmission power in the PUSCH includes an initial power component value. At this time, the power control information includes setting information of an initial power component value, and the initial power component value can be determined based on the setting information of the initial power component value. Alternatively, the initial power component value can be determined based on an initial power component value in the setting information of the initial power component value. Or, the initial power component value can be determined based on a sum value of a nominal power component value and a terminal-specific power component value in the setting information of the initial power component value.

[0185] Alternatively, when the dynamic power adjustment value is an absolute power value, the absolute power value can be determined based on a Transmit Power Control (TPC) command of the network device. The network device can send a TPC command to the terminal device, and the TPC command is used to determine the absolute power value. For example, the TPC command can carry indication information of the absolute power value, and the indication information includes, but is not limited to, an adjustment value of the absolute power value, and the absolute power value can be determined based on the adjustment value of the absolute power value in the TPC command.

[0186] Alternatively, if the dynamic power adjustment value is an accumulated power value, the accumulated power value is determined based on the sum of a previously transmitted dynamic power adjustment value and a currently transmitted absolute power value.

[0187] Optionally, the terminal device satisfies a first preset condition, and the dynamic power adjustment value is a value after performing a rollback process. Here, the dynamic power adjustment value being a value after performing a rollback process means that the dynamic power adjustment value currently transmitted is the dynamic power adjustment value previously transmitted. Here, the first preset condition can be set based on an actual situation, and for example, the first preset condition includes at least one of: a disconnection message is received; a connection rejection message is received; instruction information to enter an idle state is received; and feedback information transmitted from a network device indicating successful data reception is received. Thus, when the terminal device satisfies the first preset condition, the dynamic power adjustment value is a value after performing a rollback process.

[0188] Optionally, when the terminal device meets the first preset condition, the dynamic power adjustment value is a value after performing an initialization process. Here, the dynamic power adjustment value being a value after performing an initialization process means that the dynamic power adjustment value currently transmitted is an initial value. Here, the initial value can be set based on an actual situation, for example, can be set to 0. Thus, when the terminal device meets the first preset condition, the dynamic power adjustment value is a value after performing an initialization process.

[0189] In one implementation, it is determined that the power adjustment value corresponding to the transmission power on the PUSCH includes a dynamic power addition value, where the power control information includes setting information of the dynamic power addition value, and the dynamic power addition value can be determined based on the setting information of the dynamic power addition value.

[0194] Optionally, the terminal device satisfies a third preset condition, and the dynamic power charge-up value is a value after performing a rollback process. Here, the dynamic power charge-up value being a value after performing a rollback process means that the dynamic power charge-up value currently transmitted is the dynamic power charge-up value previously transmitted. Here, the third preset condition can be set based on an actual situation, and for example, the third preset condition includes at least one of: a disconnection message is received; a connection rejection message is received; instruction information to enter an idle state is received; and feedback information transmitted from a network device indicating successful reception of data is received. Thus, when the terminal device satisfies the third preset condition, the dynamic power charge-up value is a value after performing a rollback process.

[0195] Alternatively, when the terminal device satisfies a third preset condition, the dynamic power charge-on value is a value after the initialization process. Here, the dynamic power charge-on value being a value after the initialization process means that the dynamic power charge-on value currently transmitted is an initial value. Here, the initial value can be set based on the actual situation, for example, can be set to 0. Thus, when the terminal device satisfies the third preset condition, the dynamic power charge-on value is a value after the initialization process.
