  • Blind detection method and system for physical downlink control channel (PDCCH)
    Patent number: 10165562
    Abstract: A blind detection method and system for a PDCCH. The method comprises: acquiring PDCCH data; grouping the PDCCH data according to a location identifier of a resource element, and obtaining soft bit data according to each set of PDCCH data after grouping; acquiring control channel soft bit data from the soft bit data; determining DCI data according to the control channel element soft bit data; and acquiring a random access radio network temporary identifier according to the DCI data, to complete blind detection of a PDCCH. The technical solutions in the present application are applicable to a case in which an RNTI of a user is not determined, can ensure accuracy of blind detection of a PDCCH, and greatly reduce a calculation amount and a calculation time.
