摘要： A method for retransmitting high-speed packet data in a transmission apparatus of a mobile communication system that simultaneously performs Automatic Retransmission reQuest (ARQ) that retransmits an ARQ packet reconfigured by allocating a sequence number to data delivered from an upper layer, and Hybrid Automatic Retransmission reQuest (HARQ) that multiplexes a plurality of ARQ packets into one HARQ packet and performs repeated retransmission on the HARQ packet within a maximum retransmission limit value. A transmitting HARQ entity checks a missing ARQ packet and sends a Negative Acknowledgement (NACK) for the missing ARQ packet to a transmitting ARQ entity. The transmitting ARQ entity receives an Acknowledged (ACK) for ARQ packets from a receiving ARQ entity, detects at least one missing ARQ packet according to the NACK and the ACK, configures a retransmission packet with the detected ARQ packet, and retransmits the retransmission packet.

摘要： A method for requesting retransmission of high-speed packet data in a receiving Automatic Retransmission reQuest (ARQ) entity of a mobile communication system that simultaneously performs Hybrid Automatic Retransmission reQuest (HARQ) and ARQ. The method includes, upon receipt of a packet, determining a sequence number of the received packet, and determining if there is at least one missing packet preceding the received packet; if there is at least one missing packet, driving a first timer which is set to a time required when a number of retransmission attempts reaches a predetermined maximum number of HARQ retransmissions, and monitoring receipt of the missing packet; and upon expiration of the timer, sending to a transmitting ARQ entity an Acknowledgement (ACK) including a last sequence number among sequence numbers of normally received consecutive ARQ packets.

摘要： A method for a connection mode terminal to hand over between a home cell and a public cell in a mobile communication system is provided. In the mobile communication system including the home cell and the public cell, a region of the terminal is determined and a random access channel for the handover is pre-allocated. When the normal handover from the home cell to the public cell fails, the access to the public cell is accomplished using the pre-allocated random access channel. Therefore, the handover failure rate can be lowered.

摘要： A timing error compensation system in an OFMD/CDMA communication system includes an analog-to-digital converter for converting an OFDM signal, comprised of a data symbol stream in which a pilot symbol is inserted at intervals of a prescribed number of data symbols, received from a transmitter, to a digital OFDM symbol stream by prescribed sampling synchronization, a guard interval remover for removing a guard interval inserted in the OFDM symbol by prescribed frame synchronization, and a fast Fourier transform (FFT) device for performing fast Fourier transform on the guard interval-removed OFDM symbol and outputting a data symbol stream. In the time error compensation system, a pilot symbol detector receives the data symbol stream and detects the pilot symbols inserted in the data symbol stream at prescribed intervals. A timing compensator determines a linear phase difference line for the detected pilot symbol, generates a timing error estimation signal according to the determined linear phase difference line, and provides the timing error estimation signal to the analog-to-digital converter and the guard interval remover so as to determine the sampling synchronization and the frame synchronization.
