Abstract: PURPOSE: A repetitive transceiving device/method of non-memory error correction channel coding are provided to maximumly obtain time diversity of a demodulated symbol, when repetitively transmitting a coded signal through the non-memory error correction channel coding. CONSTITUTION: In a transmitting unit(100), an information generator(110) generates data to be transmitted. A coding unit(120) performs channel coding for the data outputted from the information generator(110) and repeats the channel coded data, to output a symbol to be transmitted. A symbol transmitter(130) receives the symbol to be transmitted, and multiplexes and modulates the symbol with another symbols, for outputting to a receiving unit(200). The receiving unit(200) receives a signal transmitted from the transmitting unit(100), for demodulation, demultiplexing, repetitive restoring, and channel coding, to obtain information.

Abstract: The channel coding of data groups to be transmitted, is carried-out in a transmitter (100). The transmitter also performs multiplexing and modulation of data groups to output transmission signal. A receiver (200) demodulates received transmission signal and also performs demultiplexing and channel decoding, to output data signal. An Independent claim is also included for method for repeated transmission and reception of coded symbols.

Abstract: Provided is a method and apparatus for discontinuously transmitting/receiving packets for low-power consumption of a terminal in a cellular system for packet transmission. The present research provides a method and apparatus that can perform a low-power consuming operation when a terminal is in active state in a cellular system. The method for discontinuously transmitting/receiving packet data to reduce power consumption of a terminal in a cellular system, including the steps of: a) establishing discontinuous reception/transmission (DRX/DTX) parameters including discontinuous DRX/DTX cycle information for terminals operating in a transmission suspension mode, which is a sub-state of an active state; and b) performing DRX/DTX based on the DRX/DTX parameters in the terminals operating in the transmission suspension mode.
