Patent ID: 7949343

Claim:
Method performed by a processor, comprising: dynamically varying a carrier separation or guard band between two carriers in a wireless communication system in response to a triggering of or a periodic dynamic change request of the guard band; determining, in response to the triggering of or the periodic dynamic change request, a number of users and a respective Quality of Service associated with each user of the number of users; calculating a tolerable overlap of the guard bands between the two carriers; selecting in response to the tolerable overlap a lowest Quality of Service data or user requirement criteria and a highest Quality of Service data or user requirement criteria; positioning the lowest Quality of Service data or user requirement criteria to the edge of one of the carriers, and positioning the highest Quality of Service data or user requirement criteria towards the middle of one of the carriers; determining an amount of frequency spectrum available for usage in the guard band; expanding or reducing bandwidth of the two carriers to increase or decrease the separation between the two carriers, and calculating an Adjacent Channel Interference level between the two carriers.
