Abstract: Methods and apparatuses are provided for transmitting data in a mobile station of a wireless communication system. Hopping information including a number of sub-bands and a size of a sub-band is identified. Resource allocation information is identified. A resource index is determined for transmitting the data based on the resource allocation information, and determining a resource index change in a unit of a sub-band, a resource index change in a unit of a resource unit, the number of sub-bands, and the size of the sub-band. The data is transmitted using the determined resource index. Each sub-band includes at least one resource unit, and each resource unit includes a plurality of subcarriers.

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.
