A radio receiving apparatus (40, 80) comprising: a receiver (41, 81) configured to receive an OFDM multicarrier signal including a first plurality of subcarriers assigned to a data channel and a second plurality of subcarriers assigned to a control channel; and a down-converting section (43, 94) configured to down-convert the received OFDM multicarrier signal; and wherein the down-converting section is further configured to use a common local frequency to down-convert the control channel and the data channel; wherein the first plurality of subcarriers is located in two separate parts on a frequency axis, and wherein the second plurality of subcarriers is located between the two separate parts; and wherein a center frequency of the first plurality of subcarriers is the same as a center frequency of the second plurality of subcarriers; characterized in that the second plurality of subcarriers is located at the center frequency so that the control channel can be received at a low sampling rate according to a bandwidth of the control channel; and wherein the data channel is received after the reception of the control channel; and wherein the radio receiving apparatus further comprises: a channel selection section (46, 85) configured to control a band-pass filter (44, 83) to have a pass-band to match the control channel smaller than the pass-band to match the data channel; and further configured to control an analog-digital conversion section (45, 84) to sample the control channel at a sampling rate to match the bandwidth of the control channel, which sampling rate is lower than the sampling rate used to sample the data channel. a receiver (41, 81) configured to receive an OFDM multicarrier signal including a first plurality of subcarriers assigned to a data channel and a second plurality of subcarriers assigned to a control channel; and a down-converting section (43, 94) configured to down-convert the received OFDM multicarrier signal; and wherein the down-converting section is further configured to use a common local frequency to down-convert the control channel and the data channel; wherein the first plurality of subcarriers is located in two separate parts on a frequency axis, and wherein the second plurality of subcarriers is located between the two separate parts; and wherein a center frequency of the first plurality of subcarriers is the same as a center frequency of the second plurality of subcarriers; characterized in that the second plurality of subcarriers is located at the center frequency so that the control channel can be received at a low sampling rate according to a bandwidth of the control channel; and wherein the data channel is received after the reception of the control channel; and wherein the radio receiving apparatus further comprises: a channel selection section (46, 85) configured to control a band-pass filter (44, 83) to have a pass-band to match the control channel smaller than the pass-band to match the data channel; and further configured to control an analog-digital conversion section (45, 84) to sample the control channel at a sampling rate to match the bandwidth of the control channel, which sampling rate is lower than the sampling rate used to sample the data channel. a channel selection section (46, 85) configured to control a band-pass filter (44, 83) to have a pass-band to match the control channel smaller than the pass-band to match the data channel; and further configured to control an analog-digital conversion section (45, 84) to sample the control channel at a sampling rate to match the bandwidth of the control channel, which sampling rate is lower than the sampling rate used to sample the data channel.
