Abstract
To enable spectrum shaping also when excess band is used, at least one set of spectral flatness requirements amongst two or more sets comprises at least at least a first parameter value for a first in-band range, at least a second parameter value for a second in-band range and at least a third parameter value for the excess band range, and a set to be used is selected at least based on information on the use of the excess band.
Claims20
An apparatus comprising
- at least one processor;
- and
- at least one memory storing instructions that when executed by the at least one processor, cause the apparatus at least to perform:
- selecting, using at least first information on whether an excess band is used in transmissions from the apparatus, a set of spectral flatness requirements amongst two or more sets of spectral flatness requirements, wherein at least one of the two or more sets comprises at least a first parameter value for a first in-band range, at least a second parameter value for a second in-band range and at least a third parameter value for an excess band range associated with the excess band;
- and
- defining spectrum shaping using at least the set of spectral flatness requirements selected.
An apparatus comprising
- at least one processor;
- and
- at least one memory storing instructions that when executed by the at least one processor, cause the apparatus at least to perform:
- causing informing a first apparatus using in-band and excess band in transmissions from the first apparatus to the apparatus whether a spectrum shaping is performed to received transmissions;
- and
- performing spectrum shaping of received transmissions at least by performing channel estimation on an in-band allocation and an excess band allocation for transmissions from the first apparatus.
A method for an apparatus, the method, when performed by the apparatus, comprising:
- selecting, using at least first information on whether an excess band is used in transmissions from the apparatus, a set of spectral flatness requirements amongst two or more sets of spectral flatness requirements, wherein at least one of the two or more sets comprises at least a first parameter value for a first in-band range, at least a second parameter value for a second in-band range and at least a third parameter value for an excess band range associated with the excess band;
- and
- defining spectrum shaping using at least the set of spectral flatness requirements selected.
A method for an apparatus, the method, when performed by the apparatus, comprising:
- causing informing a first apparatus using in-band and excess band in transmissions from the first apparatus to the apparatus whether a spectrum shaping is performed to received transmissions;
- and
- performing spectrum shaping of received transmissions at least by performing channel estimation on an in-band allocation and an excess band allocation for transmissions from the first apparatus.
A non-transitory computer-readable medium comprising program instructions, which, when run by an apparatus, causes the apparatus to carry out at least one of a first process or a second process,
- wherein the first process comprises:
- selecting, using at least first information on whether an excess band is used in transmissions from the apparatus, a set of spectral flatness requirements amongst two or more sets of spectral flatness requirements, wherein at least one of the two or more sets comprises at least a first parameter value for a first in-band range, at least a second parameter value for a second in-band range and at least a third parameter value for an excess band range associated with the excess band;
- and
- defining spectrum shaping using at least the set of spectral flatness requirements selected;
- wherein the second process comprises:
- causing informing a first apparatus using in-band and excess band in transmissions from the first apparatus to the apparatus whether a spectrum shaping is performed to received transmissions.
