ABSTRACT:
The guard band between two carriers of the same or different operators is reduced or dynamically adjusted by initiating a dynamic change request of the guard band between the two carriers to allow for flexible spectrum use by adjusting the tolerable guard band overlap. The data is distributed or positioned in the carrier spectrum band as a function of the Quality of Service so that the lowest Quality of Service constrained data are positioned at the edges of the carrier spectrum band and the highest Quality of Service constrained data are positioned in the middle of the carrier spectrum band to minimize any impact from the increased adjacent channel interference due to the guard band overlap and narrower guard band.
