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： Disclosed is a method and apparatus for transmitting reverse data by a mobile station in a mobile communication system supporting a Hybrid Automatic Repeat reQuest (HARQ). In the mobile station, a controller determines the maximum number of transmissions for a transmission encoder packet if there is an initial transmission subpacket for the encoder packet, and generates an information sequence representing a size of the encoder packet, a number of retransmissions, and a determined maximum number of transmissions. A transmitter encodes the information sequence and transmits the encoded information sequence together with the initial transmission subpacket in the same time period as a time period for transmitting the initial transmission subpacket.

摘要： An apparatus and method for transmitting/receiving a PDCCH (Packet Data Control Channel) for efficient packet data transmission in a communication system supporting packet data service. To allow both TDM-transmission and TDM/CDM-transmission of packet data, the PDCCH has a different format depending on the transmission scheme of the packet data. A receiver operates in BSD (Blind Slot Detection) to detect the transmission scheme of received packet data and the format of the PDCCH.

摘要： Disclosed is an apparatus for generating an error detection information bit sequence for determining a length of data sequence transmitted in a communication system. The apparatus comprises a plurality of cascaded registers, the number of which is identical to the number of bits in the error detection information bit sequence, and a plurality of adders arranged on paths determined by a predetermined generator polynomial, each of the adders adding a bit sequence received through an input path to a feedback bit sequence. During reception of the control information sequence, an operator generates the feedback bit sequence by sequentially adding bits of the control information sequence to output bits of a final register and provides the generated feedback bit sequence to the adders. After completion of receiving the control information sequence, the operator sequentially adds a preset input bit to output bits of the final register and outputs the addition result as the error detection information bit sequence. An initial value controller provides the registers with a selected initial value separately determined for the data sequences.
