Abstract

An uplink power control parameter configuration method, a terminal, and a network device are provided. The method includes: receiving a power control parameter set sent by a network device; determining a target parameter configuration index or a target parameter value for a first power control parameter item from the parameter set of the power control parameter item of the power control parameter set; and determining 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.

Claims (40)

1 . A computer readable storage medium, wherein a computer program is stored in the computer readable storage medium, and a processor executes the computer program to perform:

receiving more than one power control parameter sets sent by a network device, wherein the power control parameter set comprises a parameter set of at least one parameter configuration index or parameter value;

determining a target parameter configuration index or a target parameter value according to Downlink Control Information (DCI) for an uplink channel;

wherein the determining the target parameter configuration index or the target parameter value according to the DCI comprises:

when a target indication field is detected in the DCI, then determining the target parameter configuration index or the target parameter value according to the target indication field, from the power control parameter set;

when the target indication field is not detected in the DCI, then determining the default parameter configuration index or the default parameter value of a first power control parameter set as the target parameter configuration index or the target parameter value;

transmitting the uplink channel according to the target parameter configuration index or the target parameter value, wherein the uplink channel comprises a Physical Uplink Shared Channel (PUSCH);
