Abstract: Provided are a radio transmission device and a radio transmission method capable of improving downlink and uplink throughput even when performing dynamic symbol allocation. In the device and the method, BS and MS share a table correlating a basic TF as a combination of parameters such as TB size used for transmitting only user data, an allocation RB quantity, a modulation method, and an encoding ratio, with a derived TF having user data of different TB size by combining L1/L2 control information. Even when multiplexing L1/L2 control information, Index corresponding to the basic TF is reported from BS to MS.

Abstract: A wireless communication base station device, terminal device, and method have reduced signaling while maintaining high scheduling gain. A judgment unit pre-stores a correspondence between the number of code words and the number of clusters to reduce the maximum value for the number of clusters allocated to each terminal as the number of code words increases, and thus determines the maximum value for the number of clusters based on the number of code words acquired. Based on the number of code words for a transmission signal from a terminal, an estimated value for the reception quality, and the maximum value for the number of clusters that is output by the judgment unit, a scheduling unit schedules the allocation of the transmission signal transmitted by each terminal to a transmission band frequency (frequency resource) so as not to exceed the maximum value for the number of clusters.

Abstract: A communication terminal eliminates collision of access request signals simultaneously transmitted from communication terminals in a local cell, prevents generation of interference signals in another cell adjacent to the local cell, and improves local cell throughput. A base station controls transmission power of the access permission signal so as to prevent generation of an interference signal in another cell adjacent to the local cell. A use sub-channel selection unit has a correspondence table between the reception quality of the pilot signals divided into classes and the sub-channel allocated to the classes. According to the table, the use sub-channel selection unit selects a sub-channel group of RACH correlated to the measurement result of the reception quality of the pilot signals reported from the reception quality measurement unit. One sub-channel to be used for transmission of the access request signal is selected at random from the sub-channel group selected.

Abstract: A radio communication device capable of lightening the influence of a frequency selective fading in the wide-band transmission of a single carrier thereby to prevent deterioration of error rate characteristics. In this device, an FFT unit subjects a modulated signal inputted from a modulation unit to a Fourier transformation. A pilot insertion unit inserts a pilot symbol into a plurality of individual frequency components of the modulated signal. Weight multiplication units multiply the individual frequency components and the pilot symbols inserted into the individual frequency components, by weight coefficients set at a weight coefficient setting unit. IFFT units subject the frequency components to an inverse Fourier transformation, thereby to convert the frequency components into time domains.

The first communication circuit performs wireless communication with a gateway using a first communication system. The second communication circuit performs wireless communication with the gateway using a second communication system having a higher transmission speed than the first communication system. The controller is configured to activate the second communication circuit when the first communication circuit receives an activation request signal from the gateway, and to establish a link between the second communication circuit and the gateway when the first communication circuit receives a connection request signal from the gateway after the second communication circuit is activated.

Abstract: In order to reduce interference between cells through hopping and use frequencies in a good propagation situation, a scheduler section carries out scheduling for determining to which user data should be sent using CQI from each communication terminal apparatus, selects a user signal to be sent in the next frame and determines in which subcarrier block the data should be sent. Au MCS decision section selects a modulation scheme and coding method from the CQI of the selected user signal. A subcarrier block selection section selects a subcarrier block instructed by the scheduler section 102 for each user signal. For the respective subcarrier blocks, FH sequence selection sections select hopping patterns. A subcarrier mapping section maps the user signal and control data to subcarriers according to the selected hopping pattern.
