Abstract: Methods and apparatuses are provided for determining a resource for an acknowledgement signal in a wireless communication system. A transceiver of a user equipment (UE) receives a parameter associated with one or more resource blocks (RBs) for periodic transmission of a channel quality indication (CQI) signal in an operating bandwidth. A controller of the UE determines an RB for transmission of the acknowledgement signal, based on the parameter. The transceiver transmits the acknowledgement signal on the determined RB. The RB for the transmission of the acknowledgement signal is not more outer than the one or more RBs for periodic transmission of the CQI signal in the operating bandwidth.

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.

Abstract: Methods and apparatuses are provided for transmitting a signal using a sequence in a wireless communication system. A first sequence used to transmit a first signal in a first channel is determined by performing group-hopping using a pseudo-random pattern over a first group of sequences. A second sequence used to transmit a second signal in a second channel is determined by performing the group-hopping using the pseudo-random pattern over a second group of sequences.
