Method, apparatus, and system for transmitting and receiving information of an uncoded channel in an orthogonal frequency division multiplexing system

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