Abstract
Abstract A radio communication system that utilizes an available frequency spectrum that is divided up into a plurality of channels to be used by the radio communication system is operated in accordance with a frequency hopping strategy that permits a user to simultaneously utilize more than one channel during each hop period, wherein it is permissible, but not mandatory, for at least one of the channels utilized by the user during a first hop period to again be used by the user during an immediately following second hop period, so long as at least one of the channels utilized by the user during the second hop period is different from all of the channels utilized by the user during the first hop period. In some embodiments, the number of channels simultaneously utilized by any one user need not be the same as the number of channels simultaneously utilized by any other user.
