    摘要: An apparatus and method for providing a broadcasting service in a mobile communication system. The apparatus and method can transmit broadcasting service data using orthogonal frequency division multiplexing (OFDM) symbols in the mobile communication system. Broadcasting service data is encoded and modulated. The modulated data is demultiplexed into data streams corresponding to a number of orthogonal frequency subcarriers. The data streams are transformed using Fast Fourier Transform (FFT). The transformed data streams are multiplexed using OFDM. Information with a predetermined length placed in a last part of OFDM data is copied. The copied information is added as a cyclic prefix (CP) to a head part of the OFDM data, and OFDM symbols to be transmitted are generated. The generated OFDM symbols are multiplexed into a forward channel of the mobile communication system, and the multiplexed OFDM symbols are transmitted.

    摘要: An apparatus and method transmits a packet data symbol in a high-rate packet data (HRPD) mobile communication system for broadcasting service. A transmission processor generates a modulated symbol by encoding, interleaving and modulating a physical layer packet to be transmitted, and arranges the modulated symbol in a data tone. A tone inserter inserts a guard tone and a pilot tone into the data tone. A tone power allocator sets a different pilot-to-data tone power ratio according to a position of a slot, in which the packet data symbol is included, and allocates power according to the pilot-to-data tone power ratio. A transmitter transmits the packet data symbol.

    摘要: For reverse transmission/reception of rate control bits, a receiver in a mobile station transmits a message indicating combinability of rate control bits received from several base station systems through signaling, thereby securing efficient transmission/reception of the rate control bits, and improving reliability of the rate control bits. In addition, for reverse transmission/reception of ACK/NACK bits, a receiver in a mobile station transmits a message indicating combinability of ACK/NACK bits received from several base station systems, thereby securing efficient transmission/reception of the ACK/NACK bits, and improving reliability of the ACK/NACK bits.
