Claim:
1. A wireless terminal, comprising: an antenna; and, a processor, coupled to the antenna, the processor configured to receive, through the antenna, a common reference signal transmitted from a base station at a first timing at a frequency which is selected in accordance with identification information of a cell corresponding to the base station, wherein the common reference signal mapping is restricted to a resource element other than a resource element were a common reference signal of an adjacent cell is mapped, to receive, through the antenna, a wireless-terminal-specific reference signal and a control signal both of which are concurrently transmitted by the base station at different frequencies, at a second timing that is different from the first timing, wherein the control signal is mapped to a resource element other than a resource element to which the common reference signal is mapped, and wherein the second timing is a timing when the common reference signal of the adjacent cell is not transmitted; and, to demodulate the received control signal, based on the received wireless-terminal-specific reference signal.
