COMMUNICATION SYSTEM, BASE STATION APPARATUS, MOBILE TERMINAL APPARATUS AND COMMUNICATION METHOD

摘要

The present invention is designed to use frequency resources effectively, even in the situation where a plurality of mobile terminal apparatuses of varying capabilities coexist. A communication system, in which a mobile terminal apparatus (10) and a base station apparatus (20) communicate using a basic carrier and an extended carrier that is additionally allocated to the basic carrier, in which: the base station apparatus has a setting section (310) that sets, in the extended carrier, a subframe of a first carrier type which can be received in each of a plurality of mobile terminal apparatuses of varying capabilities and a subframe of a second carrier type which can be received in part of the plurality of mobile terminal apparatuses, and a transmission section (203) that transmits the basic carrier and the extended carrier to the mobile terminal apparatus, and the mobile terminal apparatus has a receiving section (103) that receives the basic carrier and the extended carrier from the base station apparatus.
