METHOD AND APPARATUS FOR CONTROLLING UPLINK TRANSMISSION POWER IN WIRELESS COMMUNICATION SYSTEM SUPPORTING MACHINE-TYPE COMMUNICATION

摘要

The present invention relates to a wireless communication system. Specifically, the present invention may comprise: a step of a terminal calculating a first maximum power reduction value to be applied to a first uplink channel; and a step of transmitting, from a plurality of subframes, the first uplink channel at the maximum transmission power by applying the first maximum power reduction value. The first uplink channel is transmitted through different frequency resources within the plurality of subframes. The maximum transmission power value has different values according to frequency resources through which specific channels are transmitted. The first maximum power reduction value is a predetermined value applied during the transmission of the first uplink channel.
