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:
- receiving, by an apparatus from a network device, a first signal in a first sub-band of a carrier using a first subcarrier spacing, the carrier having a carrier bandwidth;
- wherein the carrier comprises at least a second sub-band associating with a value of a second subcarrier spacing different than a value of the first subcarrier spacing, and the first sub-band and the second sub-band are within the carrier;
- wherein the carrier having a first guard band at a first edge of the carrier bandwidth adjacent to the first sub-band, and the carrier having a second guard band at a second edge of the carrier bandwidth adjacent to the second sub-band;
- 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;
- the method further comprising receiving a scheduling to indicate a third width in frequency of a third guard band between the first sub-band and the second sub-band or between the first sub-band and a third sub-band of the carrier, wherein the scheduling indicates resource information defined by resource unit of any one of resource block, partial resource block, resource block group or sub-carrier spacing.
