Abstract
A radio communication system includes: a plurality of cells having different scrambling sequences, respectively, wherein at least two cells communicate with at lease two user terminals connected to different serving cells; and a controller which controls the plurality of cells and provides a single scrambling sequence to said at least two cells and said at least two user terminals for control signal transmission and reception.

A method for a communication apparatus, the method comprising:
- communicating with a user equipment;
- and
- transmitting a parameter to the user equipment,
- wherein an initialization value for scrambling a bit of a control channel which is different from a physical downlink control channel (PDCCH) is based on a formula as follows:
- C
- init
- ,
- 1
- =
- ⌊
- n
- s
- 2
- ⌋
-
- 2
- 9
- +
- N
- 1
