Abstract
Disclosed is a data transmission method in a mobile communication system. The data transmission method through a code sequence in a mobile communication system includes grouping input data streams into a plurality of blocks consisting of at least one bit so as to map each block to a corresponding signature sequence, multiplying a signature sequence stream, to which the plurality of blocks are mapped, by a specific code sequence, and transmitting the signature sequence stream multiplied by the specific code sequence to a receiver.

31. A method for transmitting a preamble sequence from user equipment to a base station to at least improve detection performance, the method comprising:
-
receiving, from the base station, position information of an allocated random access channel resource, the position information including frequency information and timing information; and transmitting, by the user equipment and on a random access channel, a preamble sequence to the base station to access a cellular network, wherein the preamble sequence is at least based on; a specific sequence, having a length (L), which was generated from a Zadoff-Chu Constant Amplitude Zero Auto Correlation (CAZAC) sequence, the specific sequence having been circularly shifted, the circular-shifted specific sequence having been repeated to generate a consecutive sequence having a length (N*L), wherein N is an integer greater than 1, and the preamble sequence having been generated by concatenating a single cyclic prefix (CP) to a front-end of the consecutive sequence. - View Dependent Claims (32, 33, 34)

35. A method for transmitting a preamble sequence from user equipment to a base station to at least improve detection performance, the method comprising:
-
receiving, from the base station, position information of an allocated random access channel resource, the position information including frequency information and timing information; and transmitting, by the user equipment and on a random access channel, a preamble sequence to the base station to access a cellular network, wherein the preamble sequence has the form of a single cyclic prefix (CP) concatenated to a front-end of an N-time repetition, where N is an integer greater than 1, of the product of a Zadoff-Chu Constant Amplitude Zero Auto Correlation (CAZAC) based sequence with an exponential sequence. - View Dependent Claims (36, 37, 38)

39. A method for transmitting a preamble sequence from user equipment to a base station to at least improve detection performance, the method comprising:
-
receiving, from the base station, position information of an allocated random access channel resource, the position information including frequency information and timing information; and transmitting, by the user equipment and on a random access channel, a preamble sequence to the base station to access a cellular network, wherein the preamble sequence comprises a cyclic prefix followed by a preamble concatenated with the preamble, the preamble at least based on a Zadoff-Chu Constant Amplitude Zero Auto Correlation (CAZAC) sequence. - View Dependent Claims (40, 41, 42)

43. A system that transmits a preamble sequence to a base station to at least improve detection performance, the system comprising:
user equipment adapted to; receive, from the base station, position information of an allocated random access channel resource, the position information including frequency information and timing information; and transmit, by the user equipment and on a random access channel, a preamble sequence to the base station to access a cellular network, wherein the preamble sequence comprises a cyclic prefix followed by a preamble concatenated with the preamble, the preamble at least based on a Zadoff-Chu Constant Amplitude Zero Auto Correlation (CAZAC) sequence. - View Dependent Claims (44, 45, 46)
