    摘要： There is provided a method where a terminal amplifies an MBS signal that the terminal receives using a terminal in an MBS service, transmits the amplified signal to another terminal and controls it in order to overcome the fact it is not possible to provide high quality contents over a broad area due to interference signals between MBS zones, a terminal is used as a repeater at MBS transmission time only, and an output of a repeating signal of the terminal is controlled so that an excessive interference signal for another MBS area is not generated when the terminal operates as a repeater.

    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.

    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： An optical sheet and a Liquid Crystal Display (LCD) incorporating the same. The LCD includes a sheet-like transparent substrate made of a transparent material and a microscopic structure layer formed on one surface of the transparent substrate. The microscopic structure layer has an array of microscopic structures to emit light. A liquid crystal panel is formed above the microscopic structure layer, and has defined therein a plurality of pixels to display an image. When seen from above the transparent substrate, at least a portion of the microscopic structures has parallel and non-parallel arrangements repeated one or more times in a longitudinal direction thereof with respect to one side-edge of the pixels of the liquid crystal panel.
