Abstract
A method and apparatus that allows a telecommunications system using cdma2000 1× to easily migrate to using cdma2000 3×. In other embodiments, the invention provides for better spectrum management, allows concurrent usage of a standard cdma2000 1× reverse link with a cdma2000 1× time-division-duplexing (TDD) reverse link, and provides for hardware supplementation—as opposed to total replacement—when additional services are added to an existing code-division-multiple-access (CDMA) system.
