Method And Device For Controlling Uplink Power

Abstract: The present invention proposes a method and device for controlling uplink power. A central processing unit firstly determines a path loss generation mode for a user equipment according to a predetermined rule and then transmits an instruction to the user equipment the instruction including the determined path loss generation mode so that the user equipment determines uplink power of fee user equipment according to the path loss generation mode. A user equipment acquires an instruction from a central processing unit to indicate a path loss generation mode of the user equipment. then determines a path loss of the user equipment according to the path loss generation mode indicated by the central processing unit. and then acquires uplink transmission power of the user equipment according to the determined path loss of the user equipment. With the inventive solution a central processing unit may configure a path loss generation mode flexibly for a user equipment to accommodate different uplink CoMP scenarios and thereby achieve better CoMP performance.
