    Abstract: The present invention is a method in which a base station transmits a control channel signal in an orthogonal frequency division multiplexing (OFDM) communication system, wherein the method configures a physical resource block (PRB) from multiple resource elements (REs) for a control channel signal for scheduling, allocates at least one RE to a response channel signal, the at least one RE occupying the time domain the same as that of the RE used in a resource signal transmission in a data channel region of the PRB and occupying the frequency domain nearest to the RE used in the reference signal transmission, and transmits the control channel signal for scheduling and the response channel signal.

    Abstract: A method and apparatus for transmitting and receiving information symbols in a communication system are provided. A method includes determining a channel quality indicator (CQI) and two acknowledgements; generating a first symbol based on the CQI; generating a second symbol based on the two acknowledgements, if both the CQI and the two acknowledgements are to be transmitted on a physical uplink control channel (PUCCH); and transmitting the first symbol and the second symbol on the PUCCH. 1 is applied for generating the second symbol if the two acknowledgements have a first value, −1 is applied for generating the second symbol if the two acknowledgements have a second value, j is applied for generating the second symbol if the two acknowledgements have a third value, and −j is applied for generating the second symbol if the two acknowledgements have a fourth value, wherein the j is an imaginary unit.

    Abstract: 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.
