Abstract: A method for maintaining system interference at a low level when two or more users use one resource region in a wireless mobile communication system is provided. To control an uplink transmission power in a broadband wireless mobile communication system in multi-cell environments, information regarding the number of users who share an uplink time-frequency resource region is received from a base station, a power adjustment value is calculated based on the received number of users, and the uplink transmission power is determined by reflecting the calculated power adjustment value in a reference transmission power. Here, when only one mobile station uses the uplink time-frequency resource region, the reference transmission power is equal to a transmission power of the mobile station.

Abstract: 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.

Abstract: A sequence generation method for allowing a reception end to effectively detect a sequence used for a specific channel of an OFDM communication system, and a signal transmission/reception method using the same are disclosed. During the sequence generation, an index is selected from among the index set having the conjugate symmetry property between indexes, and a specific part corresponding to the frequency “0” is omitted from a transmitted signal. In addition, a reception end can calculate a cross-correlation value between a received (Rx) signal and each sequence using only one cross-correlation calculation based on the conjugate symmetry property.
