An MBMS-GW 202 delivers multicast data from a contents management server 201 respectively to base stations 203, includes an MD coding unit 202-1 configured to partition and code the multicast data into a plurality of pieces of multiple description code data, and delivers the plurality of pieces of MD-code data respectively to the base stations 203. The base stations 203 respectively include a transmission frequency setting unit 203-1 configured to arbitrarily set a plurality of transmission carrier frequencies for respectively transmitting the plurality of pieces of MD code data, and concurrently transmit the plurality of pieces of MD code data delivered from the MBMS-GW 202 by respectively using the plurality of transmission carrier frequencies set by the transmission frequency setting unit 203-1. An LTE terminal 204 or an LTE-A terminal 205 receives, from a corresponding base station 203, any one or more of the plurality of pieces of MD code data transmitted by using the plurality of transmission carrier frequencies, and decodes and reproduces the multicast data from the received MD-code data. |
