Abstract
The present invention is a method and apparatus for providing orthogonal frequency hopping for users in a communication system. The users have user bandwidths allocated on a frequency band. A jitter space is provided with a jitter bandwidth on the allocated frequency band. If at least one of the user bandwidths is larger than the jitter space, a skip zone is determined for at least one of the user bandwidths. The skip zone is unoccupied by a starting hop of the user bandwidths when the user bandwidths are shifted in a frequency hopping.
