Classification: CPC H | IPC H

Claim 0:
1. A communication device comprising:
a receiver, which, in operation,
receives a modulation symbol set mapped to a Orthogonal Frequency Division Multiplexing (OFDM) symbol, to which a type of reference signal is also mapped, in a first subframe, and
receives the modulation symbol set mapped to another OFDM symbol, which is different from the OFDM symbol and to which the type of reference signal is also mapped, in a second subframe that is different from the first subframe; and

circuitry, which is coupled to the receiver and which, in operation,
processes the modulation symbol set received in the first subframe and in the second subframe, and
processes the type of reference signal received in the first subframe and in the second subframe.
