Abstract: Disclosed are a method and an apparatus for uplink transmission. A method for uplink transmission for a machine-type communication (MTC) terminal comprises: a step of transmitting first uplink (UL) information via a first UL channel in a first terminal-specific frequency band of a first subframe; and a step of transmitting second UL information via a second UL channel in a second terminal-specific frequency band of a second subframe subsequent to the first subframe. The first subframe and the second subframe each include a plurality of orthogonal frequency division multiplexing (OFDM) symbols. If the first terminal-specific frequency band and the second terminal-specific frequency band do not overlap one another, the second UL information may not be transmitted in a first OFDM symbol of the second subframe. Thus, a wireless resource can be efficiently utilized.
