setting, by the UE, an initial power adjustment value of the Scell according to the configuration parameter of the Scell in the configuration information if the UE meets a setting condition that the UE receives a random access response, RAR, message; and controlling, by the UE, transmit power on the Scell according to the set initial power adjustment value of the Scell; wherein the Scell comprises a secondary access carrier, SRCell, the configuration parameter of the SRCell comprises random access, RA, configuration information, the RA configuration information comprises any one or more of physical random access channel, PRACH, configuration information, preamble initial received target power, preamble format information, and an RA power ramping step; wherein the configuration information further comprises grouping information of the at least one Scell, wherein the grouping information is used to indicate that the at least one Scell is subordinate to at least one Scell group; wherein the RAR message is used to respond to an RA initiated by the UE on any one SRCell in one Scell group; wherein the setting, by the UE, an initial power adjustment value of the Scell according to the configuration parameter of the Scell in the configuration information comprises: if the UE initiates the RA on any one SRCell in one Scell group, setting, by the UE, an uplink data channel, PUSCH, initial power adjustment value of the SRCell where the RA is initiated in the Scell group to ƒ c = Δ P rampup + δ msg 2; and/or if the UE initiates the RA on any one SRCell in one Scell group, setting, by the UE, an uplink control channel, PUCCH, initial power adjustment value of the SRCell where the RA is initiated in the Scell group to g c = Δ P rampup + δ msg 2; wherein Δ P rampup is a total power ramping value of the UE that is obtained according to the RA configuration information of the SRCell in the RA process; and δ msg 2 is a power adjustment value represented by a transmit power control command, TPC, Command comprised in the RAR message received by the UE from the base station in the RA process. obtaining, by a user equipment, UE, configuration information, wherein the configuration information comprises a configuration parameter of at least one secondary carrier, Scell, configured by a base station for the UE, the UE is served by a primary carrier, Pcell and the at least one Scell;
