    摘要: A method and apparatus for mapping coded data symbols to resources in a mobile communication system. An S/P converter converts a serial signal including user data or control information into a plurality of parallel signals. A DFT unit performs Discrete Fourier Transform (DFT) on the parallel signals output from the S/P converter. A controller controls the DFT unit so that among the signals output from the S/P converter, a control channel is mapped in the maximum available resources to which the control channel can be mapped, among the resources included in a resource block, and data symbols are mapped to the remaining resources, except for the maximum available resources to which the control channel can be mapped. A subcarrier mapper allocates the signals output from the DFT unit to subcarriers. An RF processor converts a signal output from the subcarrier mapper into a radio signal.

A receiver receives dedicated scheduling assignment information for dedicated scheduling assignment from a serving Node B, and receives at least one scheduling grant indicator for common scheduling assignment from at least one non-serving Node B. A first scheduling decider determines a combined scheduling grant indicator by combining at least one scheduling grant indicator received from the at least one non-serving Node B. A second scheduling decider determines whether to use the combined scheduling grant indicator according to a predetermined reference, and a maximum rate of an uplink according to the dedicated scheduling assignment information or the combined scheduling grant indicator. A transport format decider determines a transport format of an uplink within the maximum rate.

    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 apparatus for transmitting a control channel of a base station in a mobile communication system. A downlink control channel signal generator generates a downlink control channel signal to be transmitted to a User Equipment (UE). A control channel candidate processor calculates a control channel decoding attempt order according to a state of the downlink channel. A controller determines a control channel candidate to be used, according to the calculated decoding attempt order. A mapper maps the generated control channel signal to the determined control channel candidate. A transmission processor wirelessly transmits the mapped signal.
