摘要： Disclosed is an apparatus and method for generating a QCTC (Quasi-Complementary Turbo Code) considering a characteristic of a turbo code in a packet communication system or a communication system using an ARQ (Automatic Repeat reQuest) scheme. There is provided a method for transmitting a sub-code determined by a sub-code rate identical to or different from a code rate of a turbo encoder according to a channel environment from a QCTC generated by the turbo encoder receiving an information stream and operating at the code rate. The method comprises segmenting a length N of the QCTC into a predetermined number of sections, determining spins (Sub-code Packet Identifications) corresponding to the segmented sections, and specifying one of the SPIDs allocated for initial transmission of the sub-code; calculating a number of remaining symbols represented by N-Fs, where N is a length of the QCTC and Fs is a starting symbol position of the sub-code of the QCTC; determining a last symbol position Ls of the sub-code by comparing the number of the remaining symbols with a length of the sub-code; and sequentially transmitting symbols of the sub-code from the starting symbol position Fs to the last symbol position Ls.

摘要： An apparatus and method for transmitting and receiving forward channel quality information between a base station and a mobile station in a CDMA mobile communication system supporting multimedia service including voice and data services. The mobile station transmits an absolute value symbol in at least one time slot selected from a plurality of time slots, and a relative value symbol in one of the remaining time slots. The absolute value symbol represents the signal strength of the forward channel in the at least one time slot corresponding to the selected time slot, and the relative value symbol represents a change in the signal strength of the forward channel between the at least one time slot corresponding to the one remaining time slot and the signal strength of the forward channel in a previous time slot.

摘要： A power control method during a soft handoff in a mobile communication system. A mobile station communicating with a plurality of base stations at a soft handoff measures the signal strengths of forward common pilot channels received from the base stations and transmit them to the base stations sequentially. Then the base stations control the transmission power of forward common power control channels according to the received signal strength measurements.
