SIGNAL TRANSMITTING METHOD AND SIGNAL PROCESSING METHOD, TERMINAL THEREOF, AND BASE STATION THEREOF IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a signal transmitting method, a signal processing method, and a terminal thereof in a wireless communication system. In particular, the present invention relates to a method for a terminal to generate and transmit control signals in a wireless communication system, the method comprising the steps of: generating complex-valued symbols by modulating one or more HARQ-ACK/NACK bits; generating a block of generated complex-valued symbols by multiplying the generated complex-valued symbols by a cyclic shift sequence having the length of 12; scrambling the generated block of complex-valued symbols using scrambling sequences, spreading same using orthogonal sequences and mapping same to a time-frequency resource; and generating a control signal using the mapped time-frequency resource and then transmitting same. Regarding two slots in one subframe, the orthogonal sequence used for spreading in a first slot is one of the orthogonal sequences belonging to a first orthogonal sequence group, and the orthogonal sequence used for spreading in a second slot is either one of the orthogonal sequences belonging to the first orthogonal sequence group or one of the orthogonal sequences belonging to a second sequence group, depending on whether there is a scheduling request (SR).
