An apparatus and method of reducing power consumption in a station on a wireless LAN is provided. Included is a cumulative lead time frame receiver, a self lead time frame production transmission unit, an inactive state cumulative lead time count unit, and an active state converter. When a predetermined station is in an active state, the cumulative lead time frame receiver receives a cumulative lead time frame including a cumulative lead time value from a coordinator. If the cumulative lead time value included in the cumulative lead time frame received by the cumulative lead time frame receiver is effective, the inactive state cumulative lead time count unit converts the active state of the predetermined station into an inactive state, in which less power is consumed. If the inactive state cumulative lead time count unit completes counting, the active state converter converts the inactive state into the active state.
