Claim:
1. A method for scrambling sequence configuration, comprising: obtaining, by a base station, a search space and a transmission mode corresponding to an enhanced control channel, wherein the search space comprises a user equipment specific (UE-specific) search space and a common search space, and the transmission mode comprises a localized mode and a distributed mode; performing, by the base station, a scrambling initialization operation according to the search space and the transmission mode, and determining an initialization value of a scrambling sequence; determining, by the base station, according to the initialization value of the scrambling sequence, the scrambling sequence; and scrambling, by the base station, according to the scrambling sequence, a transmission signal transmitted by a transmitter utilizing the enhanced control channel and then transmitting to a user equipment (UE), so that the user equipment which receives the transmission signal performs a descrambling operation according to the scrambling sequence in the transmission signal.
