A method is provided for checking whether information on a request for a mode change is received for a prescribed channel time such that a device configuring a network enters a power save mode when not performing data transmission/reception and a modem enters an awake state from a sleep state for the prescribed channel time. The prescribed channel time is determined to correspond to a time for transmitting a beacon. The modem of a device in a power save mode enters an awake state for a channel time period for broadcasting a beacon and then checks whether information on a power management mode change is received. If the information is not received, a sleep state is reentered. If the power management mode change information is received, power is managed by performing data transmission/reception by switching to a normal mode. |
