Abstract:
1. A method for assigning Orthogonal Walsh codes from one set of Walsh codes in one of an omni-cell or a cell sector in a code division multiple access network to create communication channels between the mobile stations and a base station, comprising: determining that there is a mobile station that requires a Walsh code and that there are not available codes from the one set of Walsh codes within the omni-cell or cell sector need to reuse a code within a defined cell area; determining an optimal mobile station whose Orthogonal code is to be reused; and assigning the determined Walsh code that is to be re-used to the mobile station that needs the Walsh code to establish a communication channel wherein the determined Walsh code is assigned to two mobile stations within one of the omni-cell or cell sector at the same time.
