1. a kind of configuration method of scrambler sequence characterized by comprisingThe corresponding search space of enhanced control channel is obtained, described search space includes the specific search space UE and common searchSpace;

  • Scrambling code initialization operation is carried out according to described search space, determines the initialization value of scrambler sequence;

    Scrambler sequence is determined according to the initialization value of the scrambler sequence;

    It will be sent after the transmission signal scrambling of the enhanced control channel transmission according to the scrambler sequence, it is described to receiveThe user equipment for transmitting signal carries out descrambling operation according to the scrambler sequence in the transmission signal;

    It is described that scrambling code initialization operation is carried out according to described search space, comprising;

    If described search space is the specific search space the UE, the specific scrambling code initialization operation of UE, the UE are carried outSpecific scrambling code initialization is determined by Cell Radio Network Temporary Identifier/Identity, Cell-RNTI C-RNTI;

    If described search space is the public search space, the specific scrambling code initialization operation of transmission node, institute are carried outIt states transmission node and specifically initializes and determined by cell ID, the cell ID is that Physical Cell Identifier or virtual subdistrict are markedKnow.
