Power Saving Class I Sleep Mode in IEEE802.16e System

This paper investigates energy saving of MS (mobile subscriber) at power saving class I sleep mode in IEEE 802.16e system. In order to minimize the MS power consumption and decrease the occupation of interface resources in serving BS (base station), the sleep mode mechanism is introduced. This paper models the energy consumption of power saving class I sleep mode under the consideration of sleep interval of variable power rather than a constant power, and two-type-returning from sleep mode. Simulation results show that the effect of power saving class I sleep mode varies depending on different parameter configurations.
