Abstract
A method is taught for transmitting message signals in a communication system having a new call entering the communication system and Walsh codes that can be active and inactive. The method includes dividing the Walsh codes into bins and determining the number of active Walsh codes in the bins. Selecting a Walsh code in accordance with the Walsh code number determination and assigning the selected Walsh code to the new call are set forth.
Claims43
An apparatus for transmitting message signals in a communications system having new calls entering the communications system and spreading codes assigned to the new calls, comprising;
- (a) means for dividing the spreading codes into bins according to indices of the spreading codes;
- (b) means for determining a number of active spreading codes in the bins;
- (c) means for selecting a spreading code in accordance with the determination of step (b);
- and
- (d) means for assigning the selected spreading code to the new call.
