1. A system comprising:
a transmitting apparatus comprising:
circuitry, which, in operation, maps first reference signals on a plural resource elements in a resource block, and maps second reference signals on a same one resource element in the resource block, the second reference signals having a polarity opposite to each other, and the first reference signals being associated with mobile stations of a first type and the second reference signals being associated with mobile stations of a second type; and
a transmitter, which, in operation, transmits the mapped first reference signals, and transmits the mapped second reference signals via a pair of antenna ports; and
a receiving apparatus comprising:
a receiver, which, in operation, receives the first reference signals and the second reference signals; and
circuitry, which, in operation, estimates one or more channel values using one or more of: the first reference signals and the second reference signals.
