Method for controlling uplink transmission power in wireless communication system and device therefor
First Claim
1. A method of controlling uplink transmission power by a user equipment in a wireless communication system, the method comprising:
- receiving an uplink power control configuration by high layer signaling;
determining whether the uplink power control configuration indicates two uplink subframe sets for uplink power control for a same serving cell; and
if the uplink power control configuration indicates the two uplink subframe sets, resetting an accumulation corresponding to the two uplink subframe sets, respectively.

Abstract
A method is provided for controlling uplink transmission power by a user equipment in a wireless communication system. An uplink signal is transmitted according to a predetermined uplink-downlink configuration to a serving cell. First transmission power control information is received on a first uplink subframe set and second transmission power control information is received on a second uplink subframe set from the serving cell. An uplink data channel is transmitted in a specific subframe contained in the second uplink subframe set according to the second transmission power control information. The uplink data channel is a physical uplink shared channel (PUSCH). The second uplink subframe set comprises at least one or more uplink subframes designated by higher layer signaling among a plurality of uplink subframes according to the predetermined uplink-downlink configuration.
