Abstract
A reference signal multiplexing method for multiple mobile stations includes: grouping together control signals for the multiple mobile stations; and multiplexing reference signals corresponding to the control signals by CDM over the same bandwidth as that of grouped control signals.
Claims6
A base station comprising:
- a receiver configured to receive a first control signal and a second control signal in a first transmission interval, the first control signal and the second control signal being multiplexed in a first transmission bandwidth, wherein
- the first control signal is Fourier transformed, mapped, inverse Fourier transformed and transmitted by a first mobile station, and the second control signal is Fourier transformed, mapped, inverse Fourier transformed and transmitted by a second mobile station;
- the receiver further configured to receive a first reference signal and a second reference signal in a second transmission interval, the first reference signal and the second reference signal being code multiplexed in the first transmission bandwidth, wherein the first reference signal is transmitted by the first mobile station and the second reference signal is transmitted by the second mobile station;
- and
- a demodulator configured to demodulate the received first control signal by using the first reference signal and the received second control signal by using the second reference signal.
