    摘要： The disclosed invention determines whether a reception packet is an MM packet or a GF packet with precision and avoids unnecessary decoding operations performed at the GF-packet-reception time and inefficient communications.An OFDM symbol including 52 tones is transmitted when the MM packet is used, but an OFDM symbol including 56 tones is transmitted when the GF packet is used. Therefore, it is verified whether or not a signal exists in an FFT output at each of ±27 and 28 shown in a subcarrier index so that the format of the reception packet is determined. Otherwise, the packet format is determined on the basis of the Cyclic-Shift amount that changes for every format. When the GF packet is used, decoding processing performed in an L-SIG and afterward is stopped.

    摘要： A radio-communication device performs processing in a communication environment in which an OFDM (Orthogonal Frequency Division Multiplexing) modulation method is used. The radio-communication device includes a signal-reception unit that receives a MIMO (Multi Input Multi Output) signal, a data-decoding unit that decodes the MIMO signal, and a data-processing unit that processes data decoded by the data-decoding unit. The radio-communication device also includes a format-determination unit that determines, based on a relative phase difference between a previous packet field and a subsequent packet field adjacent to the previous packet field, a packet format of the MIMO signal. Further, the radio-communication device includes a control unit that stops an operation of the data-decoding unit when the data-processing unit does not support the packet format, which is determined by the format-determination unit. The operation is performed in a field that comes after a field at which the format-determination unit determines the packet format.

    摘要： A user equipment includes radio communication unit that performs radio communication with a base station over a communication channel formed by aggregating a plurality of component carriers. The user equipment has a measurement unit that measures a channel quality of the communication channel, and a controller that creates a measurement report using a result of the measurement and sends the measurement report to the base station. Each data signal transmitted over the communication channel is classified into any of two or more classes depending on a QoS requirement thereof. The radio communication unit receives control information related to a mapping between each of the plurality of component carriers and the class of each data signal from the base station, and the controller controls at least one of the measurement and the sending of the measurement report, according to a procedure which varies depending on the control information. A base station performs associated functions, according to a communication method involving allocation of data to component carriers based at least in part on channel quality criteria for different data classifications.
