Patent ID: 8270600

Claim:
A base station, comprising: a first base-station-specific scrambling code generating unit configured to generate a first base-station-specific scrambling code for randomizing a pilot channel; a second base-station-specific scrambling code generating unit configured to generate a second base-station-specific scrambling code for randomizing predetermined physical channels other than the pilot channel; a sector-specific orthogonal sequence generating unit configured to generate a sector-specific orthogonal sequence; a multiplication control unit configured to output the second base-station-specific scrambling code or a result of multiplying the second base-station-specific scrambling code by the sector-specific orthogonal sequence for each of the predetermined physical channels based on whether each of the predetermined physical channels requires soft combining; and a multiplying unit configured to multiply each of the predetermined physical channels by the, second base-station-specific scrambling code or the result of multiplying the second base-station-specific scrambling code by the sector-specific orthogonal sequence that is output from the multiplication control unit, wherein the first base-station-specific scrambling code and the second base-station-specific scrambling code have a one-to-one correspondence.
