Abstract
Methods of bandwidth utilization are provided. Within a scheduling bandwidth, which may be an entire carrier bandwidth or a sub-band, scheduling is used to reserve a guard zone at the edge of the scheduled bandwidth. This can be based on the frequency localization capabilities of a transmitter that is to be scheduled. The guard zone may be defined to a resolution that is the same as the scheduling resolution in which case the guard zone is defined entirely through scheduling. Alternatively, the guard zone may be defined to a resolution smaller than the scheduling resolution in which case scheduling and further signaling may be employed to define the guard zone.

A method comprising:
- communicating, by an apparatus with a transmission and reception point(TRP), a first signal in a first sub-band of a carrier, wherein the first sub-band has a first subcarrier spacing;
- the carrier comprises a second sub-band, the second sub-band has a second subcarrier spacing different from the first subcarrier spacing;
- and the carrier having a first guard band at a first edge of the carrier and a second guard band at a second edge of the carrier, wherein there is no guard band defined between the first sub-band and the second sub-band;
- wherein the first guard band at the first edge of the carrier is adjacent to the first sub-band, and the second guard band at the second edge of the carrier is adjacent to the second sub-band, and wherein a first width in frequency of the first guard band is defined by the first subcarrier spacing, a second width in frequency of the second guard band is defined by the second subcarrier spacing, and the second guard band has a different width in frequency than the first guard band.
