Abstract
A base station apparatus in a CDMA/TDD mobile communication system is provided. A signal is formed employing a frame configuration with a plurality of time slots and spreading processing utilizes a long spreading code for identifying a cell and a short spreading code for acquiring frame synchronization. The base station apparatus includes a first control channel former that forms a first control channel including a symbol that is spread by a first short spreading code. A second control channel former forms a second control channel including a symbol spread by a second short spreading code and positioned at a same timing as the symbol spread by the first short spreading code.
Claims19
A base station apparatus in a CDMA/TDD mobile communication system in which a signal is formed employing a frame configuration with a plurality of time slots and spreading processing utilizes a long spreading code for identifying a cell and a short spreading code for acquiring frame synchronization, the base station apparatus comprising:
- a first control channel former that forms a first control channel including a symbol that is spread by a first short spreading code;
- and
- a second control channel former that forms a second control channel including a symbol spread by a second short spreading code and positioned at a same timing as the symbol spread by the first short spreading code.
A transmission method in a CDMA/TDD mobile communication system in which a signal is formed employing a frame configuration with a plurality of time slots and in which spreading processing utilizes a long spreading code for identifying a cell and a short spreading code for acquiring frame synchronization, the method comprising:
- forming a first control channel including a symbol spread by a first short spreading code;
- and
- forming a second control channel including a symbol spread by a second short spreading code and positioned at a same timing as the symbol spread by the first short spreading code.
