    摘要: A method for transmitting/receiving a data control channel in a wireless communication system that transmits packet data. The transmission method includes transmitting packet data over a packet data channel, transmitting a control channel and receiving an ACKnowledgement (ACK) signal from a terminal that has received the control channel. The reception method includes receiving packet data and a control channel, acquiring control information by demodulating the control channel, and detecting an error in the control channel, and sending the error detection result to a base station as an ACK signal, if the control channel has been transmitted to the terminal itself.

    摘要: A transmission/reception method for transmitting a control channel in an Orthogonal Frequency Division Multiplexing (OFDM) system. The transmission method includes generating a plurality of control channels such that control information for demodulation of the plurality of control channels is distributed over information of other control channels; and modulating a data channel and the control channels into a radio signal according to a predetermined transmission scheme, and transmitting the radio signal to a wireless network. The reception method includes receiving a plurality of control channels transmitted via a wireless network; and extracting control information for demodulation of the control channels from other previously received control channels, and performing the demodulation using the control information.

    摘要: A method, apparatus and system for efficiently transmitting and receiving channels are provided in a wireless communication system based on Orthogonal Frequency Division Multiplexing (OFDM). A multiplexing scheme differs according to a channel when a transmitter transmits a packet data channel, a common control channel and a control channel designated for a particular user. Uncoded 1-bit information is broadly dispersed in frequency and time domains using multiplexing technology for maximizing diversity gain in a channel for transmitting information of at least one bit to a particular user like an acknowledgement (ACK) channel. The transmitter converts a sequence obtained by multiplexing multiple bits to be transmitted to a plurality of users to parallel signals, and broadly disperses the parallel signals in the time and frequency domains. When the uncoded 1-bit information is transmitted, reception reliability is improved because channel coding and transmission are efficiently performed using a small amount of resources.
