Integrated circuit for communication resource allocation

Provided is a multicarrier communication apparatus by which information quantity of CQI reporting can be reduced. In the apparatus, each CQI is recorded in a CQI table section () by being classified into a plurality of CQI groups by following a certain rule. A CQI selecting section () estimates fluctuation range and variance of reception qualities of the entire resource block to be reported, based on an SINR value outputted from a quality level calculating section (). Then, based on the estimated values, the CQI selecting section selects a suitable CQI group in a first step, selects a suitable CQI value from among the CQIs included in the selected CQI group in a second step, and outputs the ID of the selected CQI group and the selected CQI value to a CQI generating section (). Based on such information, the CQI generating section () generates a CQI frame to be transmitted to a base station.

Communication apparatus and communication method

A wireless communication apparatus and a wireless communication method wherein even when the permissible delay amount of data is small, the permissible delay thereof can be satisfied. A data type determining part determines whether the delay of transport data or control information should be allowed or not. A pilot signal insertion control part decides, based on pilot insertion interval information and allowable delay information, that a pilot signal is placed adjacently to data that is not allowed to delay. A multiplexing part multiplexes encoded and modulated transport data with the pilot signal generated by a pilot signal generating part in such a manner that realizes the placement decided by the pilot signal insertion control part.

A wireless communication system enabling multihop communication while maintaining the system throughput and preventing degradation of the user throughput. In the system, a BS (base station) determines the relaying method (whether an RS performs reproduction relay or nonreproduction relay) of the RS (relaying station) and the MCS of multihop communication according to the reception quality (the line quality among an MSthe RS, and the BS) of the pilot for nonreproduction relay, the reception quality (the line quality between the RS and the BS) of the pilotfor reproduction relay, and the line quality (the line quality between the MSand the RS) measured at the RS. The determination result is transmitted as relay information to the RS and to the MS(a mobile station ()) through the RS. The MSencodes and modulates the uplink data with the MCS based on the relay information and transmits the data to the RS. The RS relays the uplink data while selecting nonreproduction relay or reproduction relay according to the relay information.

A wireless relay station apparatus for enabling a mobile station and a base station to reliably receive network coding data and to provide sufficient reception performance is provided.

Next, (2) the repeater places the data so that important data Sx for the mobile station and important data Sy for the eNB do not overlap, XORs (exclusive ORs) them, and generates network coding data X (X) Y. (3) The repeater applies downlink propagation inverse characteristic Hto important data portion Px (X) Sy for the mobile station and on the other hand, applies uplink propagation inverse characteristic Hto important data portion Sx (X) Py for the eNB in the network coding data X (X) Y for transmission.

There is provided a wireless communication device capable of improving a decoding performance by using an optimal selection criterion for a start address and a read direction in a circular buffer. An interlacer () writes an interleaved and interlaced bit sequence into a circular buffer (). An RV decision unit () decides the read start address and read direction of the circular buffer () based on the number of non-transmitted systematic bits, the number of non-transmitted important parity bits, and/or the number of non-transmitted unimportant parity bits. A read control unit () controls the read start address and read end address of the circular buffer (). A read unit () is controlled by the read control unit () to continuously read encoded bits from the circular buffer ().
