Abstract: A cross carrier scheduling method is provided by a terminal. The terminal receives a control element including cross carrier scheduling configuration information from a base station, and sets a scheduling cell of a secondary cell in accordance with the cross carrier scheduling configuration information. The terminal starts to monitor scheduling information of the secondary cell at the scheduling cell from a time predefined between the base station and the terminal.

Abstract: The present application relates to a scheduling device and method of a mobile communication system. In the packet scheduling method, a base station performs packet scheduling for a terminal station in a mobile communication system, and a transport channel comprising an uplink shared channel (UL-SCH) and a physical channel comprising an uplink grant channel (UL-GCH) between the terminal and the base station are classified into a plurality of channels. In addition, in the packet scheduling method: a) the base station receives scheduling information from the terminal; b) the base station allocates an uplink resource for uplink traffic transmission for terminal based on the received scheduling information; and c) information for the allocated uplink resource is transmitted to the terminal through the UL-GCH of the physical channel.

Abstract: The present invention relates to a A preamble allocation method and a random access method in a mobile communication system. In the present invention, includes allocating one among preamble resources is allocated to a specific mobile stations station in advance, before random access. The mobile stations request station requests random access by transmitting a preamble based on the pre-allocated preamble resource to a base station. It is therefore possible to prevent A collision caused by the fact that other mobile stations transmit the same preamble the same preamble transmission by another mobile station may be prevented.
