Sequence generation and transmission method based on time and frequency domain transmission unit

摘要

A method for generating/transmitting a transmission-unit symbol sequence is disclosed. In the case of transmission information, the information is modulated in time and frequency domains on the basis of a predetermined transmission unit (e.g., a transmission time interval TTI or slot), simultaneous transmission of the information is made, and then a transmission unit symbol is generated/transmitted. A transmission sequence is masked in each symbol contained in one transmission unit. Symbol-unit circular shift (cyclic shift) is applied to the masked result, so that transmission efficiency increases. A control signal transmission method for supporting a variety of formats and a signal transmission method based on a prime-length sequence are also provided.

1. A method for transmitting, by a user equipment, uplink control information in a communication system, the method comprising:
multiplying a transmission sequence “y(n)” corresponding to the uplink control information by a frequency direction sequence for each symbol “n”, that is used for transmission of the uplink control information in a transmission time interval consisting of two slots, to generate an output signal, where “n” is a symbol index; and transmitting the output signal in the transmission time interval, wherein a length of the frequency direction sequence corresponds to a number of sub-carriers contained in a resource block.
