    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.

    摘要: A transmission/reception method and apparatus in an Orthogonal Frequency Division Multiplexing (OFDM)-based wireless communication system are provided, in which a data transmitter adaptively selects a multiplexing scheme according to a code rate of the transmission packet or an effective SNR of a wireless channel for a corresponding terminal, when transmitting a packet data channel. The adaptive multiplexing scheme is equal in concept to a scheme of adaptively implementing unitary precoding. The unitary precoded multiplexing includes Orthogonal Frequency code Domain Multiplexing (OFCDM), Fast Fourier Transform-Spread-OFDM (FFT-S-OFDM), Fast Frequency Hopping-OFDM (FFH-OFDM), and the like. The method and apparatus adaptively selects the multiplexing scheme and transmits/receives data using the selected multiplexing scheme, thereby improving reception performance of the packet data.
