    Abstract: The present invention provides a method and apparatus for transmitting an ACK/NACK in a TDD system. A component carrier (CC) configuration for a user equipment (UE) and a transmission mode of each CC are received. An ACK/NACK feedback mode is selected based on an overhead status for feedback in an uplink. An ACK/NACK is processed according to the selected feedback mode. And the ACK/NACK is transmitted in the uplink. The method provided by the present invention can avoid excessive overhead for feedback in uplink in various extreme circumstances while ensuring satisfying performances of downlinks under many configurations.

    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.
