摘要： When a terminal generates an uplink signal in a communication system, the terminal hops a sequence for differentiating itself from another terminal with time. The terminal generates the uplink signal by multiplying a transmission symbol by a sequence of a transmission time corresponding to the transmission symbol.

摘要： 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.
