A method performed by a network device, the method comprising: • determining a reference service type, and determining, based on the reference service type (S 201), a value of a first type power control parameter of physical uplink shared channel, PUSCH, transmit power based on the reference service type, wherein the reference service type is: a service type used by the network device, the service type being one service type among a first service type and a further second service type, wherein services that require uplink transmission authorization are grouped into the first service type, and services that do not require uplink transmission authorization are grouped into the second service type; • when determining that a user equipment, UE, sends data with each service type, determining, for each service type, a compensation value of the PUSCH transmit power of the UE based on a quality of service requirement of the service type, thereby determining compensation values, wherein each service type means all service types among the first and second service type (S 202); • sending the value of the first-type power control parameter and the compensation values to the UE (S 203); • determining a second-type power control parameter of the PUSCH transmit power based on a target service type, wherein the target service type is a service type, among the first and second service type, whose data currently need to be transmitted by the UE to the network device on the PUSCH, and the second-type power control parameter is a transmit power control, TPC, value (S 205); • sending the second-type power control parameter to the UE (S 206); • receiving the data on the PUSCH from the user equipment. • determining a reference service type, and determining, based on the reference service type (S 201), a value of a first type power control parameter of physical uplink shared channel, PUSCH, transmit power based on the reference service type, wherein the reference service type is: a service type used by the network device, the service type being one service type among a first service type and a further second service type, wherein services that require uplink transmission authorization are grouped into the first service type, and services that do not require uplink transmission authorization are grouped into the second service type; • when determining that a user equipment, UE, sends data with each service type, determining, for each service type, a compensation value of the PUSCH transmit power of the UE based on a quality of service requirement of the service type, thereby determining compensation values, wherein each service type means all service types among the first and second service type (S 202); • sending the value of the first-type power control parameter and the compensation values to the UE (S 203); • determining a second-type power control parameter of the PUSCH transmit power based on a target service type, wherein the target service type is a service type, among the first and second service type, whose data currently need to be transmitted by the UE to the network device on the PUSCH, and the second-type power control parameter is a transmit power control, TPC, value (S 205); • sending the second-type power control parameter to the UE (S 206); • receiving the data on the PUSCH from the user equipment.
