    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.

    摘要: Provided is an uplink transmission power control method in a wireless communication system. Said method includes preferentially determining the transmission power of an uplink control channel, and determining the transmission power of an uplink data channel within the difference between the maximum transmittable power of a terminal and the transmission power of the uplink control channel, wherein the transmission of the uplink control signal through the uplink control channel and the transmission of the uplink data through the uplink data channel are performed at the same time using wireless resources different from one another. The present invention preferentially allocates the transmission power required for the transmission of an uplink control channel, and allocates residual power to an uplink data channel, thereby improving the effectiveness of power allocation when an uplink control signal and an uplink data signal are transmitted at the same time using physical resources different from one another.
