    摘要: In an apparatus for controlling reply signal transmission in a reply signal transmitter that generates and transmits a reply signal according to an error check in packet data received through a radio channel in a mobile communication system, an error detection part generates a reply signal corresponding to the error check from the packet data received through the radio channel. A spreading part spreads the reply signal to output the spread reply signal. A transmission power control part carries out a power control operation for the spread reply signal with a power value that differs according to a packet data transmission rate of a packet data channel. A transmission part transmits the reply signal outputted by the transmission power control part through a radio channel.

    摘要: A method and apparatus for transmitting a broadcast physical layer packet in a mobile communication system supporting multi-slot transmission and hybrid Automatic Repeat Request (H-ARQ) are provided. The method comprises initially transmitting the broadcast physical layer packet according to a fixed transmission format for at least one first slot interval and retransmitting the broadcast physical layer packet for at least one second slot interval using a variable transmission format different from the transmission format used in the first slot interval.

    摘要: An apparatus and method interleaving symbols coded by a turbo encoder in a communication system that uses the turbo encoder for encoding transmission information into coded systematic symbols and at least one parity symbol pair, and maps the coded symbols using a second or higher modulation order before transmission. An interleaver controller performs a control operation of cyclic-shifting the systematic symbols among the symbols coded by the turbo encoder depending on a size of a physical packet to be transmitted, the number of transmission slots, and the modulation order, using an equation of (K×c+k)mod R, and cyclic-shifting redundancy symbols constituting the remaining size of the coded symbols to be transmitted, using an equation of floor{(K×c+k)/D}mod R. An interleaver cyclic-shifts input symbols under the control of the interleaver controller.
