1. A method of receiving a Machine Type Communication (MTC) Physical Downlink Control Channel (MPDCCH), by a terminal, in a wireless communication system supporting MTC, the method comprising:
receiving, from a base station, configuration information related to transmission of the MPDCCH; and
receiving, from the base station, the MPDCCH,
wherein a control region includes first L symbols (1≤L≤4, L is a natural number) in a subframe based on the configuration information, and
wherein based on symbol indexes in the subframe being 0, 1, . . . , 13 in a time domain, and
based on L=1, the MPDCCH mapped to a symbol with symbol index 7 is additionally mapped to a symbol with symbol index 0,
based on L=2, the MPDCCH mapped to a symbol with symbol index 7 is additionally mapped to a symbol with symbol index 0, the MPDCCH mapped to a symbol with symbol index 8 is additionally mapped to a symbol with symbol index 1,
based on L=3, the MPDCCH mapped to a symbol with symbol index 7 is additionally mapped to a symbol with symbol index 0, the MPDCCH mapped to a symbol with symbol index 8 is additionally mapped to a symbol with symbol index 1, the MPDCCH mapped to a symbol with symbol index 9 is additionally mapped to a symbol with symbol index 2, and
based on L=4, the MPDCCH mapped to a symbol with symbol index 7 is additionally mapped to a symbol with symbol index 0, the MPDCCH mapped to a symbol with symbol index 8 is additionally mapped to a symbol with symbol index 1, the MPDCCH mapped to a symbol with symbol index 9 is additionally mapped to a symbol with symbol index 2, the MPDCCH mapped to a symbol with symbol index 10 is additionally mapped to a symbol with symbol index 3.
