    摘要： 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.

    摘要： A method and UE apparatus are provided for adjusting an uplink data rate by a User Equipment (UE) in a mobile communication system. The method includes determining if a current state of a buffer is an empty state or a non-empty state; when the current buffer state is the non-empty state, comparing a ratio of a total of transmission data currently stored in the buffer to a total of Transport Formats (TFs) allocated during a predetermined number n of subframes, with a predetermined threshold; setting indication information indicating satisfaction/non-satisfaction ('happy bit(s)')of an uplink data rate according to the comparison result; and transmitting the set indication information to a Node B. The UE apparatus comprises a multiplexing/demultiplexing device, a HARQ processor, a controller to set information indicating satisfaction/non-satisfaction in accordance with pre-set rules, an exemplary set of which is also provided.
