摘要： A method of transmitting a signal according to the present invention includes: receiving a signal that is encoded with a predetermined code rate and that is modulated by a first modulation method from a base station; creating a signal that is obtained by demodulating the signal that is modulated by the first modulation method using a method corresponding to the first modulation method; creating a signal that is obtained by modulating the demodulated signal using a second modulation method while maintaining the predetermined code rate; and transmitting the signal that is modulated by the second modulation to a mobile station.Therefore, it is possible to reduce the cost of the relay station and simplify the system of the relay station. Further, during the modulation and demodulation, the symbol offset is changed to create various modulated and demodulated signals.

摘要： A communication method according to the present invention includes receiving MAP in formation, acquiring an initial scheduled frame number and a current frame number from the MAP information, calculating the difference between the initial scheduled frame number and the current frame number, comparing the difference between the initial scheduled frame number and the current frame number with a reference value and setting a scheduled frame number, and performing transmission or reception in the scheduled frame. Therefore, even though a MAP loss occurs, the mobile station can receive only downlink data effective in downlink, thereby reducing power consumption for unnecessary reception, and can exactly perform transmission in a frame in which it should transmit in uplink.
