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.
Claims42
A system to transmit a preamble sequence from user equipment to a base station to at least improve detection performance comprising:
- a receiver within the user equipment capable of receiving, from the base station and over a broadcast channel, position information of an allocated random access channel resource, the position information including frequency information and timing information;
- and
- a transmitter within the user equipment capable of transmitting, using the position information, 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.
A base station that receives a preamble sequence from user equipment to at least improve detection performance comprising:
- a transmitter that transmits, to the user equipment over a broadcast channel, position information of an allocated random access channel resource, the position information including frequency information and timing information;
- and
- a receiver that receives a preamble sequence, the preamble sequence having been transmitted using the position information, and on a random access channel, 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.
A method to transmit a preamble sequence from user equipment to a base station to at least improve detection performance comprising:
- receiving, at the user equipment, from the base station over a broadcast channel, position information of an allocated random access channel resource, the position information including frequency information and timing information;
- and
- transmitting, from the user equipment, using the position information, 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.
A non-transitory computer readable information storage media having stored thereon instructions, that when executed by one or more processors, cause to be performed a method to transmit a preamble sequence from user equipment to a base station to at least improve detection performance comprising:
- receiving, at the user equipment, from the base station over a broadcast channel, position information of an allocated random access channel resource, the position information including frequency information and timing information;
- and
- transmitting, from the user equipment, using the position information, 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.
