Problems solved by technology

Performance of the uplink scheduling may be improved as frequencies for reporting the transmission buffer state are increased, but a trade-off, in which excessive radio resources are used, may be generated.
As the time for receiving the resource request from the terminal is delayed, the transmitted data are deteriorated.
However, in a conventional packet-based mobile communication system, since channels for requesting and receiving the scheduling information are not classified and the terminal transmits the scheduling information b

Abstract

The present invention 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.

Description

TECHNICAL FIELD[0001]The present invention relates to a scheduling method of a mobile communication system, and more particularly, to a packet scheduling device and method for allocating resources to uplink traffic and downlink traffic.BACKGROUND ART[0002]Recently, as systems for wireless Internet services have been actively developed and standardized, a packet transmission technique has become increasingly important, and various efforts for gaining a first mover advantage in a fourth generation packet-based mobile communication system have been made.[0003]A resource request and link packet scheduling method for satisfying a quality of service (QoS) and maximizing efficiency of radio resources is a specialized radio link sharing method, and it increases system capacity.[0004]In a resource request process, a terminal informs a base station that there are data to be uplink-transmitted, and requests resources from the base station. Scheduling methods for allocating the resources to the...
