A method implemented by a base station (4a-05-4a-20, 5a-05-5a-20, 6a-05-6a-20) to perform communication in a wireless communication system, the method comprising: determining whether a carrier of a plurality of carriers is a normal carrier or a carrier dedicated for multimedia broadcast multicast services, MBMS, wherein the carrier dedicated for the MBMS provides a MBMS service via a frequency-time resource defined as the entire time interval of a corresponding subframe; creating system information including, for each carrier of the plurality of carriers, carrier frequency information of the each carrier, a service area identity, SAI, list of the each carrier, and a condition information indicating whether the each carrier of the plurality of carriers is the normal carrier or the carrier dedicated for the MBMS; and transmitting the created system information to a terminal; determining whether multicast control channel, MCCH, information is changed corresponding to the MBMS when data for the MBMS is transmitted to the terminal via the carrier dedicated for the MBMS; and transmitting, if the MCCH information is changed, information regarding the change of the MCCH information, wherein transmitting the information regarding the change of the MCCH comprises transmitting downlink control information, DCI, containing the information regarding the change of the MCCH, based on a radio network temporary identifier, RNTI, wherein the RNTI is transmitted via a preset frequency-time resource of a preset subframe (1e-10), wherein the preset frequency-time resource is defined as the entire time interval of the preset subframe and as frequency bands of the preset subframe except for a specific frequency around the center frequency of the preset subframe, and wherein the RNTI comprises an MBMS-RNTI, M-RNTI. determining whether a carrier of a plurality of carriers is a normal carrier or a carrier dedicated for multimedia broadcast multicast services, MBMS, wherein the carrier dedicated for the MBMS provides a MBMS service via a frequency-time resource defined as the entire time interval of a corresponding subframe; creating system information including, for each carrier of the plurality of carriers, carrier frequency information of the each carrier, a service area identity, SAI, list of the each carrier, and a condition information indicating whether the each carrier of the plurality of carriers is the normal carrier or the carrier dedicated for the MBMS; and transmitting the created system information to a terminal; determining whether multicast control channel, MCCH, information is changed corresponding to the MBMS when data for the MBMS is transmitted to the terminal via the carrier dedicated for the MBMS; and transmitting, if the MCCH information is changed, information regarding the change of the MCCH information, wherein transmitting the information regarding the change of the MCCH comprises transmitting downlink control information, DCI, containing the information regarding the change of the MCCH, based on a radio network temporary identifier, RNTI, wherein the RNTI is transmitted via a preset frequency-time resource of a preset subframe (1e-10), wherein the preset frequency-time resource is defined as the entire time interval of the preset subframe and as frequency bands of the preset subframe except for a specific frequency around the center frequency of the preset subframe, and wherein the RNTI comprises an MBMS-RNTI, M-RNTI. <EOS>
