110 may include information associated with a radio resource used to transmit the first data 120 the terminal may receive information associated with the radio resource and receive the first data 120 by referring to the received information associated with the radio resource for example the terminal may be aware of information associated with a time domain or a frequency domain where the first data 120 is transmitted by referring to information associated with the radio resource the terminal may receive the first data 120 in the time domain or the frequency domain where the first data 120 is transmitted the control information 110 may include modulation and coding scheme information associated with the first data 120 or error control scheme information associated with the first data 120 the terminal may receive the modulation and coding scheme information or the error control scheme information and receive the first data 120 using the modulation and coding scheme information or the error control scheme information when the present invention is applied to a 3rd generation partnership project 3gpp long term evolution lte system control information may be transmitted using a physical downlink control channel pdcch also first data or second data may be transmitted using a physical downlink shared channel pdsch referring again to fig1 the base station may transmit data every persistent allocation interval 190 after transmitting the first data 120 the base station may transmit second data 140 to the terminal when control information 130 associated with the second data 140 is different from the control information 110 associated with the first data 120 the base station may transmit the control information 130 associated with the second data 140 to the.
