The present disclosure relates to a communication method and system for converging a 5-Generation (5G) communication system for supporting higher data rates beyond a 4-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for controlling a terminal in a base station of a mobile communication system, according to an embodiment of the present application, comprises the steps of: selecting at least one candidate terminal for offloading; obtaining information on a neighbor cell of at least one of the candidate terminals; obtaining throughput improvement information according to offloading on the basis of information on the candidate terminal and load information of the neighbor cell of the candidate terminal; obtaining information on a target cell corresponding to the candidate terminal on the basis of the throughput improvement information; selecting a target terminal to be offloaded from the candidate terminals on the basis of the throughput improvement information corresponding to the target cell; and transmitting, to the target terminal, a message instructing offloading to the target cell corresponding to the target terminal.

Method and apparatus for selecting carrier in mobile communication system

The present disclosure is to effectively perform coordinated transmission in a wireless communication system. A base station includes a controller for providing control to generate control information including channel state information and buffer occupancy state related information of terminals, and a communication unit for transmitting the control information. In addition, the present disclosure also includes other exemplary embodiments different from the aforementioned exemplary embodiments.

Apparatus and method for transmitting control information for coordinated transmission in wireless communication system

A centrifugal fan includes: an impeller configured to suction or discharge air; a motor configured to rotate the impeller; a housing configured to accommodate the impeller and have a suction port through which air is suctioned by rotation of the impeller and a discharge port through which air is discharged by rotation of the impeller; and a cut-off portion formed on one side of the discharge port. A flow cross-sectional area of air flowing in the housing is gradually increased from the cut-off portion to the discharge port in an air flow direction, and a distance from a lower portion of the impeller to an inner peripheral surface of the housing in a rotational axis direction of the impeller is gradually increased in at least a portion from the cut-off portion to the discharge port in the air flow direction.

Centrifugal fan

A centrifugal fan includes: a housing; an impeller which is mounted in the housing; a hub which is provided in the impeller and is rotated by a driving force of a motor; and a plurality of blades which radially extend at the hub. Each of the plurality of blades is formed to have a shape curved from a leading edge to a trailing edge in a rotational direction of the impeller in each of the plurality of blades. A farthest point from a plane connecting the leading edge and the trailing edge is defined as a peak portion. The peak portion is placed closer to the leading edge than the trailing edge.

A method and an apparatus for controlling coverage of a base station in a wireless communication system are provided. The method includes determining a coverage control target terminal among terminals within a service radius of the base station and increasing a coverage of the coverage control target terminal.
