摘要： Provided is a downlink control information transmitting and receiving method which can maximize the use of limited radio resources by effectively forming an uplink signaling message to be transmitted from a base station to a terminal and transmitting the formed uplink signaling message with a minimum amount of radio resources occupied. The method for transmitting downlink data generation indication information for a base station to inform a terminal of packet data transmission in a packet-based cellular system, includes the steps of: a) generating the downlink data generation indication information; b) recording radio resource allocation information in downlink scheduling information for transmitting the downlink data generation indication information, and allocating information for the downlink data generation indication information to downlink-shared radio resources; and c) transmitting the downlink scheduling information and the information for the downlink data generation indication information according to a transmission cycle.

摘要： Disclosed is a method for effectively forming uplink control information transmitted through a downlink from a base station to a terminal in a mobile communication system for providing a packet service and transmitting the uplink control information with minimum radio resources occupied. The method includes generating uplink control information; allocating the uplink control information to a downlink-shared radio resource for packet data transmission based on downlink scheduling information; and transmitting the radio resource to a terminal. The present invention is applied to a mobile communication system.

摘要： 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.

摘要： A base station infers a random access failure rate depending on a random access collision of terminals performing random access and controls a random access opportunity of a terminal that fails the random access by using the random access failure rate of each terminal. Also, information for the controlled random access opportunity is transmitted to the terminal that fails the random access.

摘要： Provided is a method and apparatus for discontinuously transmitting/receiving packets for low-power consumption of a terminal in a cellular system for packet transmission. The present invention provides a method and apparatus that can perform a low-power consuming operation when a terminal is in active state in a cellular system. The method for discontinuously transmitting/receiving packet data to reduce power consumption of a terminal in a cellular system, including the steps of: a) establishing discontinuous transmission/reception (DTX/DRX) parameters including discontinuous DTX/DRX cycle information for terminals operating in a transmission suspension mode, which is a sub-state of an active state; and b) performing DTX/DRX based on the DTX/DRX parameters in the terminals operating in the transmission suspension mode.
