Abstract

A spectral arrangement for radio resources is usable for transmitting radio data within a telecommunication network. The spectral arrangement includes (a) a first radio resource usable for transmitting radio data in a first data flow direction, wherein the first data flow direction is either an uplink direction or a downlink direction, (b) a second radio resource usable for transmitting radio data in a second data flow direction, wherein the second data flow direction is opposite to the first data flow direction, (c) a third radio resource usable for transmitting radio data in the second data flow direction and (d) a guard band, which on the frequency scale is located between the first radio resource and the second radio resource such that the first radio resource is separated from the second radio resource Between the second radio resource and the third radio resource there is provided no guard band.

Claims

a third radio resource being usable for transmitting radio data in the second data flow direction and

a guard band, which on the frequency scale is located between the first radio resource and the second radio resource such that the first radio resource is separated from the second radio resource,

wherein between the second radio resource and the third radio resource on the frequency scale there is provided no guard band such that the second radio resource the third radio resource.

2. The spectral arrangement as set forth in claim 1, wherein

the first radio resource is usable for transmitting radio data by employing a frequency division duplex radio transmission scheme.

3. The spectral arrangement as set forth in claim 1, wherein

the second radio resource is usable for transmitting radio data by employing a frequency division duplex or a time division duplex radio transmission scheme and the third radio resource is usable for transmitting radio data by employing a frequency division duplex or a time division duplex radio transmission scheme.

4. The spectral arrangement as set forth in claim 1, wherein

the first radio resource timely extends within a predefined full time interval (T) and

the second radio resource is timely limited to a predefined reduced time interval (Tr) being included in the full time interval (T).

5. The spectral arrangement as set forth in claim 4, further comprising

a fourth radio resource being usable for transmitting radio data in a first data flow direction adjoins the first radio resource,

wherein the guard band is timely limited to the reduced time interval (Tr),

wherein with respect to the full time interval (T) the fourth radio resource is timely limited to a complementary reduced time interval (Tc) of the reduced time interval (Tr) and

wherein on the frequency scale the forth radio resource adjoins the first radio resource.

6. The spectral arrangement as set forth in claim 5, further comprising
