The present disclosure discloses a baseband data storage control method, including: receiving cell configuration information of each subframe, mapping each cell into a preset cell set according to bandwidth and quantity of antennas in the cell configuration information, where each cell set corresponds to a random storage region; analyzing each cell included in each cell set and cell parameters corresponding to each cell, and computing storage addresses for each cell in the random storage region according to obtained cell parameters; and storing received baseband data into a random storage region corresponding to a cell to which the baseband data belong, according to the computed storage address. The present disclosure further discloses a baseband data storage control device.
