Uplink power control parameter configuration method, terminal and network device

A terminal, comprising a processor, a memory and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to:

• receive a power control parameter set sent by a network device, wherein the power control parameter set comprises a parameter set of at least one power control parameter item, and the parameter set of each power control parameter item comprises at least one parameter configuration index or parameter value;
• determining the target parameter configuration index or the target parameter value for the first power control parameter item according to Downlink Control Information (DCI);
• and
• determine a target transmit power of an uplink channel or an uplink reference signal according to the target parameter configuration index or the target parameter value;
• wherein the processor executes the computer program to perform
• detecting whether the DCI comprises a target indication field;
• when the target indication field is detected, determining the target parameter configuration index or the target parameter value for the first power control parameter item according to the target indication field, from the parameter set of the power control parameter item of the power control parameter set;
• when the target indication field is not detected, determining the default parameter configuration index or the default parameter value as the target parameter configuration index or the target parameter value of the first power control parameter item;
• or determining the target parameter configuration index or target parameter value of the first power control parameter item based on the second power control parameter item whose parameter configuration index or parameter value is determined.

An uplink power control parameter configuration method, applied to a network device side, comprising:

• sending a power control parameter set to a terminal, wherein the power control parameter set comprises a parameter set of at least one power control parameter item, and the parameter set of each power control parameter item comprises at least one parameter configuration index or parameter value;
• sending Downlink Control Information (DCI) carrying a target indication field to the terminal, to enable the terminal to:
• detect whether the DCI comprises a target indication field;
• when the target indication field is detected, then determine the target parameter configuration index or the target parameter value for the first power control parameter item according to the target indication field, from the parameter set of the power control parameter item of the power control parameter set;
• when the target indication field is not detected, then determine the default parameter configuration index or the default parameter value as the target parameter configuration index or the target parameter value of the first power control parameter item;
• or then determine the target parameter configuration index or target parameter value of the first power control parameter item based on the second power control parameter item whose parameter configuration index or parameter value is determined;
• and
• receiving an uplink channel or an uplink reference signal sent by the terminal at a target transmit power, wherein the target transmit power is determined by the terminal according to a target parameter configuration index or a target parameter value of a first power control parameter item in the power control parameter set.
