Abstract
A first orthogonal codeset, obtainable in various manners, is used in a first cell to provide orthogonal spreading codes for traffic signals originating within the first cell. A second orthogonal code set for use in a second cell is obtained that has at least a first code in common with the first orthogonal code set by selecting any code in the first codeset to be the first common code. The plural orthogonal codesets can be utilized in various ways and in various environments. For example, the plural orthogonal codesets can be used for operation of a user equipment unit in a code division multiple access (CDMA) network.
