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.

Claims

1. A method of controlling uplink transmission power by a user equipment in a wireless communication system, the method comprising:

transmitting an uplink signal according to a predetermined uplink-downlink configuration to a serving cell;

receiving first transmission power control information on a first uplink subframe set and second transmission power control information on a second uplink subframe set from the serving cell; and

transmitting an uplink data channel in a specific subframe contained in the second uplink subframe set according to the second transmission power control information,

wherein the uplink data channel is a physical uplink shared channel (PUSCH), and

wherein 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.
