    Abstract: A method and an apparatus for CQI(Channel Quality Indicator) control for adaptive modulation and coding in an OFDMA system improve capacity and fairness of the OFDMA system by variably controlling a size of a sub carrier group. A valid cluster is selected among clusters including one bin or more which are a plurality of subcarrier groups according to a predetermined standard(S335). An average CINR(Carrier-to-Interference-plus-Noise Ratio) of the valid cluster is calculated(S337). The optimum MCS level of each valid cluster is determined based on the average CINR value(S353). The optimum cluster among the valid clusters is determined based on the optimum MCS level(S373).

    Abstract: A UWB(Ultra Wide Band) transceiver for frequency sharing and a transceiving method are provided to reduce interference effect of an external device by selectively controlling transmission power, thereby making frequency sharing with the external device available. An external signal detector(120) detects an external signal generated from an external system. If an external signal using the same frequency channel as a UWB transceiver is detected, a transmission signal controller(130) determines size of a transmission signal of the UWB transceiver according to size of the detected external signal. If the external signal is not detected, a maximum power generator(160) generates a maximum power level of the transmission signal.

    Abstract: A method for sensing spectrum and arranging quiet period in a cognitive radio system, a CPE(Customer Premise Equipment), a base station and a superframe structure using the same are provided to increase the reliability of detection regarding whether an incumbent user appears in his/her frequency channel. A base station(800) using a method for sensing spectrum and arranging quiet period in a cognitive radio system comprises a transceiver(802) and a sensor(804). The base station(800) constructs a WRAN(Wireless Regional Area Network) with the first CPE(810) and the second CPE(820). The first CPE(810) includes a transceiver(812) and a sensor(814). The second CPE(820) includes a transceiver(822) and a sensor(824). The transceiver(802) communicates with the first CPE(810) via the first frequency channel CH_1, communicates with the second CPE(820) via the second frequency channel CH_2, and does not perform transmission via the first or the second frequency channel CH_1 or CH_2 during a QP of the base station(800). The transceiver(802) may transmit information on the assignment of QPs of the first and second frequency channels CH_1 and CH_2 belonging to an active set to the first CPE(810) and the second CPE(820). The transceiver(802) may receive each result obtained by performing spectrum sensing for the first CPE(810) and the second CPE(820) from the first CPE(810) and the second CPE(820). Therefore, the base station(800) can utilize a result obtained by performing spectrum sensing and the results obtained by performing spectrum sensing for the first CPE(810) and the second CPE(820), thereby performing more reliable spectrum sensing. The sensor(804) performs spectrum sensing for the first frequency channel CH_1 during a QP of the first frequency channel CH_1, converts the first frequency channel CH_1 into the second frequency channel CH_2 before a QP of the second frequency channel CH_2, and performs spectrum sensing for the second frequency channel CH_2 during a QP of the second frequency channel CH_2.
