Abstract
A signal transmitting method according to an exemplary embodiment of the present invention includes channel-coding broadcasting channel information by using a first scrambling code in a first frame within a broadcasting channel information updating period including a plurality of frames, and channel-coding the broadcasting channel information by using a second scrambling code in a second frame within the broadcasting channel information updating period. The second scrambling code is different from the first scrambling code.
Claims15
A method of transmitting a signal in a base station, the method comprising:
- updating transmission information every transmission information updating period including a plurality of frames;
- applying channel-coding to the transmission information by using a scrambling code in each frame within the transmission information updating period;
- converting channel-coded transmission information to a transmission symbol;
- and
- transmitting the transmission symbol,
- wherein different scrambling codes are used for different frames within the transmission information updating period.
An apparatus for transmitting a signal in a base station, the apparatus comprising:
- means for updating transmission information every transmission information updating period including a plurality of frames;
- means for applying channel-coding to the transmission information by using a scrambling code in each frame within the transmission information updating period;
- means for converting channel-coded transmission information to a transmission symbol;
- and
- means for transmitting the transmission symbol,
- wherein different scrambling codes are used for different frames within the transmission information updating period.
A method of generating a signal in a base station, the method comprising:
- applying channel-coding to transmission information by using a first scrambling code in a first frame within a transmission information updating period including a plurality of frames;
- and
- applying channel-coding to the transmission information by using a second scrambling code in a second frame within the transmission information updating period, the second scrambling code being different from the first scrambling code.
