Method for controlling uplink power in wireless communication system and device therefor

摘要

The present invention relates to a wireless communication system and, more specifically, provides a method for controlling uplink power and a device therefor. The method whereby user equipment controls uplink transmission power in a wireless communication system according to one embodiment of the present invention may comprise the steps of: receiving configuration information regarding a plurality of subframe sets from a base station; receiving, in the subframe index j, transmission power control (TPC) information from the base station; and determining transmission power for an uplink channel in the subframe index i on the basis of the TPC information. The TPC information may be applied to a power control process related to a first subframe set, to which the subframe index i belongs, among the plurality of subframe sets.

1. A method for performing uplink transmit power control by
a user equipment in a wireless communication system, the method comprising: receiving configuration information about a plurality of subframe sets from a base station; receiving transmit power control (TPC) information from the base station in a subframe #j; and determining a transmit power for an uplink channel in a subframe #i based on the TPC information, wherein the TPC information is applied to a power control process associated with a first subframe set including the subframe #i among the subframe sets, wherein the TPC information is not applied to a power control process associated with a second subframe set among the subframe sets, wherein the first subframe set includes at least one subframe whose purpose of use is flexibly changeable from the configuration information, and wherein the second subframe set includes at least one subframe whose purpose of use is statically set according to the configuration information.
