Communication apparatus and method of receiving downlink control information and data and transmitting uplink control information

Abstract

An integrated circuit includes receiving circuitry and transmitting circuitry. The receiving circuitry, in operation, controls reception of a downlink control information on one or more consecutive control channel elements (CCEs) in a search space, and controls reception of downlink data on a downlink resource that is indicated by the downlink control information, the search space being comprised of a plurality of CCEs that includes the one or more consecutive CCEs, and the plurality of CCEs starting on a CCE that is determined from both a number of the one or more consecutive CCEs, and a total number of CCEs configured in a subframe. The transmitting circuitry, in operation, controls transmission of uplink control information on an uplink resource, which is associated with a CCE index of a first CCE of the one or more consecutive CCEs.
