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.
Claims12
A method for reassigning physical channels of a user service experiencing high interference levels in a hybrid wireless time division multiple access/code division multiple access communication system, the method comprising:
- checking a measured interference of each potential reassignment time slot not belonging to the user service to determine whether any potential reassignment time slot has a lower interference than the highest measured interference for a time slot of the user service;
- ordering the time slots of the user service in a descending order of measured interference if there is at least one potential reassignment time slot having a lower interference than the highest measured interference for a time slot of the user service;
- and
- sequentially evaluating and reassigning the user service physical channels in each time slot in the time slot order in a descending order of a desired reception quality of each physical channel of the user service.
A radio network controller (RNC) for use in a hybrid wireless time division multiple access/code division multiple access communication system, the RNC comprising:
- a radio resource management (RRM) device for a user service experiencing high interference levels, for checking a measured interference of each potential reassignment time slot not belonging to the user service to determine whether any potential reassignment time slot has a lower interference than the highest measured interference for a time slot of the user service, for ordering the time slots of the user service in a descending order of measured interference, and sequentially evaluating and reassigning the user service physical channels in each time slot in the time slot order in a descending order of a desired reception quality of each physical channel of the user service.
A radio network controller (RNC) for use in a hybrid wireless time division multiple access/code division multiple access communication system, the RNC comprising:
- means for a user service experiencing high interference levels, for checking a measured interference of each potential reassignment time slot not belonging to the user service to determine whether any potential reassignment time slot has a lower interference than the highest measured interference for a time slot of the user service;
- means for ordering the time slots of the user service in a descending order of measured interference;
- and
- means for sequentially evaluating and reassigning the user service physical channels in each time slot in the time slot order in a descending order of a desired reception quality of each physical channel of the user service.
