ABSTRACT:
Physical channels of a user service experiencing high interference levels are to be reassigned in a hybrid time division multiple access/code division multiple access communication system. Time slots of the user service are ordered in a descending order of the measured interference. The user service physical channels in each time slot are sequentially evaluated and reassigned in the time slot order in a descending order of a desired reception quality of each physical channel of the user service.
