Abstract
The present disclosure provides a method and an apparatus for demodulating a downlink channel in a communication system, and a baseband chip. The demodulation method may include: obtaining RE data corresponding to the downlink channel successively from an OFDM symbol; demodulating the RE data to obtain demodulated data; filling the demodulated data to a corresponding position in a downlink channel buffer; and proceeding to obtain RE data corresponding to the downlink channel successively from a next OFDM symbol if a sequence number of the OFDM symbol does not reach a predetermined number. The present disclosure saves buffer space of the baseband chip in a UE.
