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.

Claim
1. A method of transmitting broadcast channel information in a base station, the method comprising:
generating broadcast channel information every transmission time interval including a plurality of consecutive frames;
scrambling the broadcast channel information with a scrambling code in the transmission time interval;
modulating the scrambled broadcast channel information to generate transmission symbols; and
transmitting the transmission symbols,
wherein the scrambling code has different codes in different consecutive frames within the transmission time interval.
2. The method of claim 1, further comprising:
encoding the broadcast channel information; and
rate matching the encoded broadcast channel information.
3. The method of claim 2, wherein rate matching the encoded broadcast channel information comprises:
storing bits of the encoded broadcast channel information to a circular buffer; and
extracting bits in a circle from the circular buffer.
4. A method of transmitting broadcast channel information in a base station, the method comprising:
generating broadcast channel information every transmission time interval including a plurality of consecutive frames;
scrambling the broadcast channel information with a scrambling code in the transmission time interval;
wherein the scrambling code has different codes in different consecutive frames within the transmission time interval;
modulating the scrambled broadcast channel information to generate transmission symbols;
transmitting the transmission symbols; and
initializing the scrambling code every transmission time interval.
5. A method of receiving broadcast channel information in a terminal, the method comprising:
receiving transmission symbols;
blindly acquiring a timing of a transmission time interval including a plurality of consecutive frames; and
extracting broadcast channel information from the transmission symbols,
wherein the broadcast channel information included in the transmission symbols is scrambled with a scrambling code in the transmission time interval,
wherein the scrambling code has different codes in different consecutive frames within the transmission time interval; and
wherein the scrambling code is initialized every transmission time interval.
6. A non-transitory computer-readable medium having a program stored thereon for executing a method of transmitting broadcast channel information in a base station, the method comprising:
generating broadcast channel information every transmission time interval including a plurality of consecutive frames;
scrambling the broadcast channel information with a scrambling code in the transmission time interval;
modulating the scrambled broadcast channel information to generate transmission symbols; and
transmitting the transmission symbols,
wherein the scrambling code has different codes in different consecutive frames within the transmission time interval.
7. A non-transitory computer-readable medium having a program stored thereon for executing a method of transmitting broadcast channel information in a base station, the method comprising:
generating broadcast channel information every transmission time interval including a plurality of consecutive frames;
scrambling the broadcast channel information with a scrambling code in the transmission time interval;
wherein the scrambling code has different codes in different consecutive frames within the transmission time interval;
modulating the scrambled broadcast channel information to generate transmission symbols;
transmitting the transmission symbols; and
initializing the scrambling code every transmission time interval.
8. A non-transitory computer-readable medium having a program stored thereon for executing a method of receiving broadcast channel information in a terminal, the method comprising:
receiving transmission symbols;
blindly acquiring a timing of a transmission time interval including a plurality of consecutive frames; and
extracting broadcast channel information from the transmission symbols,
wherein the broadcast channel information included in the transmission symbols is scrambled with a scrambling code in the transmission time interval,
wherein the scrambling code has different codes in different consecutive frames within the transmission time interval; and
wherein the scrambling code is initialized every transmission time interval.
