    摘要: A method for controlling transmission power of a physical random access channel in a mobile communication terminal. The mobile communication terminal sets initial transmission power according to received signal code power when a preamble of the physical random access channel is transmitted to a mobile communication network. A wireless channel environment is identified on the basis of a value of the received signal code power when the preamble must be retransmitted. According to the identified wireless channel environment, transmission power used in a previous preamble is variably increased and retransmission power is set.

    摘要: A transmitting/receiving apparatus and method for packet retransmission in a mobile communication system. Upon request for a retransmission from a receiver, a transmitter inverts initially transmitted coded bits if the retransmission is odd-numbered for the same data, modulates the inverted bits, and transmits the modulated bits to the receiver. Then the receiver recovers the coded bits by demodulation. If the coded bits are retransmitted an odd number of times, the receiver decodes the coded bits after inversion. Thus the error probabilities of initial transmission bits and retransmission bits are averaged in effect and decoding performance is improved.

    摘要: In an apparatus for data transmission in a communication system, a turbo encoder encodes data bits to generate systematic bits and parity bits, and a rate matcher matches the systematic bits and parity bits. A first interleaver writes the rate-matched systematic bits on a row by row basis, and performs inter-column permutation. A second interleaver writes the rate-matched parity bits on a row-by-row basis, and performs inter-column permutation. A modulator alternatively collects the permutated bits on a column by column basis from the first and second interleavers, and maps collected bits from the first and second interleavers onto one modulation symbol, wherein a size of the first interleaver is equal to a size of the second interleaver.

    摘要: A method and apparatus for transmitting/receiving control information to support High Speed Downlink Packet Access (HSDPA) in a WCDMA communication system are provided. When transmitting new packet data, a Node B sets a New data Indicator (NI) to a specific bit value indicating an initial transmission for the packet data. Upon receipt of a retransmission request for the packet data, the Node B sets the NI as the inverse of a previous NI. If an redundancy version (RV) representing a constellation and a data type for packet data, is set to a specific value indicating an initial transmission, the Node B set the NI to the inverse of the specific bit value regardless of the previous NI. A User Equipment (UE) receives control information including the NI and the redundancy version (RV) and determines that the packet data is initial transmission data or retransmission data, according to the NI and the RV.
