1. one kind is sent the method for replying (ACK) channel information by the base station in OFDM (OFDM) system, and this method comprises:

  • Orthogonal code through using in the mutually orthogonal sign indicating number set is come spread spectrum (703) ack channel information;

    With the ack channel information mapping (705) of the pattern of the diversity gain that increases ack channel information spread spectrum to subcarrier;

    With other channel information of channel coding schemes coding;

    AndMultiplexing and send the ack channel information that (707) are mapped to subcarrier with other channel information of having encoded.
