1. the method for the search volume of a configurating downlink control channel is characterized in that, comprising:

  • When the alternative E-PDCCH parameter of Physical Downlink Control Channel (E-PDCCH) search volume that configuration strengthens, other alternative E-PDCCH parameter of each polymer grade is determined by the bit number of resource element (RE) number that can be used for E-PDCCH in each subframe and/or Downlink Control Information (DCI) form;

    UE determines corresponding alternative E-PDCCH parameter according to current residing descending sub frame and the DCI form that detects, and in E-PDCCH search volume corresponding to this alternative E-PDCCH parameter the alternative E-PDCCH of blind Detecting.
