1. A communication apparatus comprising:

  • a receiver which, in operation, receives a signal including downlink control information;

    a controller which, in operation, sets a division number based on a number of OFDM symbols used for an Enhanced Physical Downlink Control CHannel (EPDCCH), the division number being a number of Control Channel Elements (CCEs) per resource block pair, and, in operation, specifies a plurality of resource region candidates by using the division number, each resource region candidate including at least one CCE, wherein the controller, in operation, sets the division number such that the division number for a subframe having a Normal cyclic prefix length is larger than the division number for a subframe having an Extended cyclic prefix length; and

    a decoder which, in operation, decodes the plurality of resource region candidates to obtain the downlink control information.
