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 first uplink-downlink (UL-DL) configuration information from a base station through a system information block; receiving second UL-DL configuration information for a downlink hybrid automatic repeat and request (HARQ) operation from the base station; receiving a transmission power control (TPC) order from the base station; and determining uplink transmission power for a first uplink channel on the basis of the first UL-DL configuration information and the TPC order and determining uplink transmission power for a second uplink channel on the basis of the second UL-DL configuration information and the TPC order.
