A method of power management for a mobile station in a multi-carrier wireless network is provided. A primary connection between the mobile station and a serving base station is first established by performing initial ranging over a primary radio frequency (RF) carrier. A secondary connection between the mobile station and the base station is then established by performing periodic ranging over a secondary RF carrier. To achieve efficient power management, the mobile station performs Open Loop Power Control and obtains long-term link measurement (CSI) of the primary carrier. The mobile station then adjusts carrier-specific parameters based on the primary carrier CSI. For RF carriers that convey on-going data traffic, Close Loop Power Control is updated per RF carrier. When the mobile station enters sleep mode operation, it receives traffic indication messages on the primary RF carrier and then dynamically wakes up one or more corresponding RF carriers for data reception.
