Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the present disclosure, in a wireless communication system, a base station comprises: at least one transceiver, and at least one processor coupled to the at least one transceiver. The at least one processor may be configured to: control the at least one transceiver to transmit first data based on a first hybrid automatic request (HARQ) process; control the at least one transceiver to transmit second data based on the first HARQ process; based on transmitting the second data, generate third databased on the result of the first data being received; and control the at least one transceiver to transmit the third data based on a second HARQ process.

Abstract: An electronic device includes a camera module, wherein the camera module includes a lens assembly including lenses aligned along an optical axis, an actuator, a first magnet disposed on a first surface of the lens assembly, a first coil configured to move the lens assembly along the optical axis, a metal shield structure disposed on an outer surface of the actuator to face the first coil, and a fixing structure disposed on a third surface perpendicular to the first surface of the lens assembly, wherein at least a portion of the fixing structure has a magnetic property. When one end of the fixing structure is inserted into an opening of a housing, the fixing structure is fixed in an optical axis direction by the opening and is fixed in the first direction by a magnetic force acting on the metal shield structure.

Abstract: A scheduling apparatus and a method for interference control in a mobile communication system supporting a carrier aggregation or dual connectivity or multi-connectivity technology in which a terminal uses a plurality of frequency resources at the same time are provided. Specifically, a first base station in a wireless communication system includes a transceiver and a processor connected to the transceiver and configured to obtain resource information of a second base station transmitted by the second base station, determine a resource assignment pattern based on the resource information of the second base station, assign uplink (UL) resources of the LTE base station for an UL channel based on the resource assignment pattern to reduce interference, and assign uplink (UL) resources of the first base station for an UL channel based on the resource assignment pattern to reduce interference.
