Method and device for controlling interference
A method for controlling interference includes: dividing a control region in a time domain transmission unit to obtain first and second power regions, the transmission power of the first power region being higher than that of the second power region; dividing all current channels to obtain first and second channel groups; transmitting data carried by all the channels included in the second channel group by means of the first power region, and transmitting data carried by all the channels included in the first channel group by means of the second power region. The method can greatly reduce interference to a PDSCH of a small cell from a PDCCH of a macro base station when the macro base station and the small cell use different parameter sets on the same carrier in a heterogeneous network, without reducing the spectrum utilization rates of the macro base station and the small cell.
