The integrated shooting simulation system using a fisheye lens camera, according to the present invention, includes: a main body for implementing a shooting simulation by executing a shooting program; a display device for receiving images, which are related to the shooting simulation, from the main body, and displaying the same; a fisheye lens camera mounted at the display device and capturing a shooting image displayed on the display unit; and a simulation gun, wherein the main body and the display unit are integrally formed.

Abstract: Provided are a scheduling apparatus and method for a multicast broadcast service. Scheduling information is configured with at least one of information related to a location in which each multicast broadcast service, which is identified by a unique identifier within one scheduling period, starts and information related to a location in which each multicast broadcast service ends, and a scheduling block including the configured scheduling information is generated. There is an advantage that power management of user equipment is easy, and a time delay when initially entering the MBMS and a channel change time when selecting a different MBMS are reduced.

Abstract: Disclosed are channel management methods in a multicarrier structure in a mobile communication system. Uplink (UL) and downlink (DL) channel management methods in a carrier aggregation environment are used as the channel management methods. In DL, a base station determines a component carrier (CC) of an unstable radio channel state, stops data retransmission by the CC, and notifies a terminal of retransmission stop. In UL, the base station determines a CC of an unstable radio channel state and instructs the terminal to stop data retransmission by the CC, and the terminal stops the data retransmission and initializes a retransmission buffer.

Abstract: Disclosed is a carrier management method for use in a carrier aggregation environment of a mobile communication system. In the method, a base station is configured to transmit a deactivation message for a secondary carrier to a terminal and change the secondary carrier to a deactivation state after a predetermined time from the transmission of the deactivation message. The terminal receives the deactivation message transmitted by the base station, and changes the secondary carrier to the deactivation state after a predetermined time from the transmission of the deactivation message. As the predetermined time, a predefined value may be used to prevent inconsistency of secondary-carrier state information that is managed by the base station and the terminal. If the carrier state management information is used, it is possible to prevent inconsistency of secondary-carrier states that are managed by the base station and the terminal and solve problems due to the inconsistency.

Abstract: Disclosed are channel management methods in a multicarrier structure in a mobile communication system. Uplink (UL) and downlink (DL) channel management methods in a carrier aggregation environment are used as the channel management methods. Using the channel management methods in the mobile communication system employing the multicarrier structure, an increase in the number of unnecessary retransmissions is prevented, so that unnecessary retransmission and power consumption of the terminal can be reduced and the waste of radio resources and the degradation of base station performance due to unnecessary retransmission can be prevented.
