    摘要: A wireless communication terminal apparatus and a CQI selecting method wherein when CQIs are grouped according to their levels and then an upper-order CQI, which is indicative of a group, is to be informed in a longer period, while a lower-order CQI, which identifies a CQI in the group, being to be informed in a shorter period, the CQI is precisely selected. A reception SIR range of 0-4 dB in UE corresponds to a level 1 of upper-order CQI. A next reception SIR range of 4-8 dB corresponds to a level 2 of upper-order CQI. Similarly, the following SIR ranges up to 24 dB, each of which is 4 dB higher than a respective previous one, correspond to the respective following levels of upper-order CQI. On the other hand, the levels 1-4 of lower-order CQI, with which the level 1 of upper-order CQI is associated, correspond to a SIR range of −1-5 dB. The levels 1-4 of lower-order CQI, with which the level 2 of upper-order CQI is associated, correspond to a SIR range of 2-9 dB. Thus, the SIR ranges, to which the lower-order CQIs correspond, overlap the respective SIR ranges corresponding to the respective adjacent levels of upper-order CQIs with which the lower-order CQIs are associated.

    摘要: Provided is a radio transmission device capable of improving reception accuracy of a unicast channel received after a multicast channel. In the radio transmission device, a multicast transmission power control unit (106) performs control to reduce the transmission power of the OFDM symbol at the end of a sub frame for a multicast signal outputted from a CP insertion unit (105-2). A radio transmission unit (108) transmits a unicast signal multiplexed by a sub frame multiplexing unit (107) and a multicast signal of controlled transmission power via a transmission antenna (109).
