Abstract: A method for transmitting and receiving a CQI(Channel Quality Indicator) in a multi-carrier radio system is provided to feed back a suitable CQI according to a change in a channel environment, without an additional control channel, as compared with an existing periodic CQI feedback method, and without an increase in the use of resources for CQI feedback, by using a terminal's report indicator and a base station's control information response for it. If a measurement point comes according to a preset measurement cycle(201), a terminal confirms whether the first timer is on(202). In case the value of the first timer is '0', the terminal confirms how much channel quality has been changed(203,204). If the difference between a currently measured channel quality value and a previously measured channel quality value is larger than a preset threshold, the terminal confirms whether the measurement point is matched with a CQI feedback cycle(205). If not, the terminal confirms whether data are being transmitted through the uplink or downlink with a base station(207). In case data transmission is being executed, the terminal selects a suitable control channel and transmits the first report indicator to the base station(208). Then the terminal receives response information from the base station and confirms it(210). If the received response information indicates that the base station accepts the terminal's CQI transmission(211), the terminal transmits a varied CQI through resources allocated for feedback(212).

The user terminal generates channel state information according to the channel state value converted into the channel state information report type(304). The user terminal transmits the generated channel state information to the base station(306).

Abstract: An apparatus for controlling the states of a terminal, a method thereof, and an apparatus for transferring a paging message are provided to increase efficiency in using radio resources and to minimize the power consumption of a terminal by controlling state transition of the terminal according to QoS levels and applying different mobility management methods according to states of the terminal. A state control apparatus comprises a state control part(410), which exists in a network layer(III), and a sub-state control part(430), which exists in a data link layer(II). The state control part(410) sets a terminal to become a connected state or a disconnected state. Also the state control part(410) transits disconnected state of the terminal to an active state or an idle state. The sub-state control part(430) transits the active state of the terminal to an active sub-state or an idle sub-state. The state control part(410) allocates shared radio resources when the terminal is in the active state. The sub-state control part(430) measures the level of QoS through a measurement channel when the terminal is in the active sub-state, and allocates a part of shared radio resources dedicatedly to the terminal. The sub-state control part(430) inactivates the measurement channel when the terminal is in the idle sub-state. The sub-state control part(430), when the terminal is in the idle sub-state, operates a control channel and a data channel in a DTX(Discontinuous Transmission) or DRX(Discontinuous) method.

Abstract: A state control device of a cellular system and a controlling method are provided to control state transition of a terminal according to QoS(Quality of Service) and the type of a packet service, thus efficient use of radio resources is possible while power consumption is reduced. When the state of a terminal is set as an active state, a resource manager(410) allocates reverse and forward traffic channels to the terminal, and if the state is set as an idle state, the manager(410) enables the terminal to stop synchronous maintenance for the reverse traffic channel. When a sub state of the active-state terminal is set as a scheduling state, a scheduler(440) allocates resources of the reverse and forward traffic channels to the terminal according to QoS supported to the terminal, and when the sub state is set as a scheduling excluding state, the scheduler(440) enables the terminal to non-continuously transceive packet data through the reverse and forward traffic channels.
