Abstract: PURPOSE: A method for controlling the transmission speed of a reverse traffic channel in a mobile communication system is provided to enable a mobile terminal to properly select a transmission speed control mode or a schedule mode, and to determine a data rate of a traffic channel, thereby magnifying a reverse system capacity. CONSTITUTION: A mobile terminal determines a transmissible data rate of a reverse traffic channel after a predetermined time section(310). The mobile terminal decides whether to use a transmission speed control mode or a schedule mode according to the determined data rate(320). If the transmission speed control mode is used, the mobile terminal transmits an IAB(Increase Availability Bit) informing a base station that the data rate can be up-converted(330). If the schedule mode is used, the mobile terminal transmits request information including the determined data rate to the base station to directly request a desired data rate, and transmits the IAB to the base station(340).

CONSTITUTION: C/I(CQICH(Channel Quality Indicator Channel) Information) measurement for carriers 1, 2 and 3(501a,501b,501c) respectively measure a C/I value for forward pilot channel signals received from three carriers, and output the C/I measurement values to an average calculator. Then, the average calculator(503) obtains an average value of the C/I measurement values. The average value obtained by the average calculator(503) is inputted to a C/I information generator(504), and the C/I information generator(504) generates the average value as 4-bit absolution value C/I information or a 1-bit relative value C/I information.

Abstract: PURPOSE: A method for reporting downlink channel quality in a wideband CDMA communication system using an HSDPA(High Speed Downlink Packet Access) system is provided to determine detailed information on channel quality for a downlink channel with a measured carrier to noise ratio, and to transmit the determined information to a base station, thereby enabling a user terminal to transmit downlink channel quality information as minimizing an uplink interference. CONSTITUTION: A UE(User Element) measures a C/I(Carrier to Interference) ratio by using a CPICH(Common Pilot Channel)(602), and checks whether a current TTI(Transmission Time Interval) is a multiple of M TTI(603). If so, the UE determines a TFRC(Transport Format and Resource Combination) by using a BLER threshold value or the measured C/I ratio(605). The UE channel-codes the determined CQ refreshment information, transmits the channel-coded information to a CQI(Channel Quality Indicator) of an HS-DPCCH(High Speed-Dedicated Physical Control Channel), and returns to the step '602'. If the current TTI is not the multiple of the M TTI, the UE checks whether the current TTI is a multiple of N TTI(604). If so, the UE determines CQ refreshment information corresponding to the CQ refreshment information transmitted during M TTI period(606).

Abstract: PURPOSE: An apparatus and a method for controlling power of an F-CPCCH(Forward- Common Power Control Channel) are provided to transmit a power control command for controlling the power of a reverse link. CONSTITUTION: A sector receives a CQICH(Channel Quality Indicator Channel) and a reverse PICH(Pilot Channel) from a terminal(301).

Thereafter, the sector checks whether the sector division information indicates the base station. When the sector division information does not indicate the base station, the power control bit is extracted from the received reverse PICH and the power of the CQICH is controlled according to the extracted power control bit(305).

Abstract: PURPOSE: A method for distributing energy for packet data channels in a high speed packet data transmission mobile communication system is provided to re-arrange location of symbols to allocate much energy to more important symbols, when energy allocated to packet data channels is changed during transmissions, thereby increasing a receiving success rate of data. CONSTITUTION: An energy distribution block inputs code symbols of a sub-packet through packet data channels from a puncturer(701). The energy distribution block inputs various types of control information on the inputted sub-packet(702).

The energy distribution block controls an order of symbols inputted to a modulator by using the inputted control information(704). The modulator modulates the symbols inputted from the energy distribution block, and generates the modulated symbols(706).
