A scheduling method and apparatus in a wireless communication system. The scheduling method for a node B in a wireless communication system supporting a plurality of carriers includes determining a delay weight for each of a plurality of user equipment (UEs) according to a preset weight application time point. The method also includes determining a scheduling metric value of each UE per carrier using the delay weight, and determining a priority of each UE per carrier using the scheduling metric value.

A handover method in a plurality of wireless networks includes selecting one or more candidate networks from the plurality of wireless networks available to a mobile terminal of a user; calculating the latest connection time with a serving network currently serving the mobile terminal; deriving a history utility function based on the latest connection time; deriving system utility functions of the candidate networks in consideration of user and system environments; deriving selection functions for the candidate networks using the history utility function and the system utility functions; and selecting one of the candidate networks as a target network for handover using the selection functions. A target network for handover is selected using not only a system utility function reflecting user and system parameters but also a history utility function reflecting history information, thereby reducing the number of handovers and enhancing service quality.

A cognitive radio communication apparatus and method to control a sensing operation. The cognitive radio communication apparatus includes an information receiver to receive channel state information associated with a channel occupancy state of a primary system from at least one sensing node of a secondary system; a sensing control unit to control a sensing period of the at least one sensing node according to a change pattern of the channel occupancy state, based on the channel state information; and a control information transmitter to transmit control information associated with the controlled sensing period to at least one member node of the secondary system.
