The invention discloses method and device for transceiving business description information in a digital audio broadcasting system. The method includes: business description information is sequentially subjected to scrambling, forward error correction coding, bit interleaving and constellation mapping to obtain modulation symbols during transmitting; the modulation symbols are placed on reserved symbols and carriers thereof in residual capacity of the system in distributed manner according to a system frame structure and are multiplexed with other signal elements into frequency domain signals; the frequency domain signals are converted into time domain signals for transmission; the time domain signals are converted into frequency domain signals which are demultiplexed into effective carriers during receiving; and distributed business description information symbols are extracted from the effective carriers according to the system frame structure, and the symbols are then sequentially subjected to demapping, de-interleaving, forward error correction decoding and descrambling to obtain business description information. By the use of the method and device, credibility of the business description information symbols being transmitted in the residual capacity can be increased, and the digital audio broadcasting system is effectively guaranteed to support rich programs and flexible business modes.
