Classification: CPC H | IPC H

Claim 4:
5. A receiving apparatus comprising:
a scheduler configured to assign discontinuous frequency bands and transmission times within a predetermined period to at least one transmitting apparatus,
wherein the scheduler sets, in the predetermined period, a first transmission period for orthogonal frequency division multiplex transmission and a second transmission period for single carrier block transmission,
wherein the scheduler assigns the first transmission period for transmitting a known signal that is a reference signal used for demodulating the first signal in the second transmission period and is from the at least one transmitting apparatus, discontinuous frequency bands used for transmitting the known signal being arranged so as not to be overlapped among at least one transmitting apparatus, and
wherein the scheduler assigns the second transmission period fhr transmitting data from the at least one transmitting apparatus;

a transmitter configured to transmit, to the at least one transmitting apparatus, assignments by the scheduler; and
a receiver configured to receive the known signal and the data from the at least one transmitting apparatus.
