Disclosed are a power control method, a UE, a base station, a parameter configuration method and a control method. The power control method comprises: receiving at least one piece of configuration information, where the configuration information comprises at least one sounding reference signal (SRS) resource set, the reference signal resource set comprises at least one SRS resource, the SRS resource set is identified by an SRS resource set index, and the SRS resource is identified by a first SRS resource index; receiving at least one power control parameter set; receiving an association one between the SRS resource set and a power control parameter, or an association two between SRS and the power control parameter; and determining a power control parameter of an SRS corresponding to the SRS resource according to the received configuration information, power control parameter set and one of the association one or the association two.
1. A power control method, comprising:
receiving, by the user equipment, UE, at least part of parameters in an open-loop power control parameter set of an uplink transmission, an association between an open- loop power control parameter identification and a reference signal index, and an association between a closed-loop power control process identification and the reference signal index;
resetting a local closed-loop power adjustment amount corresponding to a closed-loop power control process identification associated with the index of the received open-loop power control parameter set,
wherein the open-loop power control parameter set is indicated by the open-loop power control parameter identification, and the closed-loop power control process is indicated by the closed-loop power control process identification.
2. The method of claim 1 , wherein the uplink transmission comprises at least one of:
