摘要： A radio transmitting apparatus and a radio transmitting method wherein a guard interval having a variable length is used to allow a radio receiving apparatus to precisely and easily obtain a symbol synchronization. In the radio transmitting apparatus, a GI adding part (103) adds a short GI or a long GI, which is longer than the short GI, to the head of each of data parts into which a modulated signal outputted from a modulating part (102) has been put by a predetermined number of symbols. In a case of adding the short GI, the GI adding part (103) copies the symbols of a portion of the data part including the rear thereof, and adds the copied symbols to the head of that data part, thereby providing a GI. In a case of adding the long GI, the GI adding part (103) copies the symbols of a portion of a second data part, which immediately follows the first data part, including the rear of the second data part. Then, the GI adding part (103) adds the copied symbols to the head of the first data part, thereby providing the second GI. Moreover, the GI adding part (103) copies the symbols of a portion of the first data part including the rear thereof, and then adds the copied symbols to the head of the second GI added to the first data part, thereby providing the first GI.

摘要： Provided is a resource allocation method capable of improving a reception quality when connecting a plurality of sub frames into one frame and performing a communication process for each of the frames. In this method, when a sub frame #1 is transmitted, LRB is selected as a resource allocation format according to CQI fed back from a mobile station and RB having a preferable propagation quality is allocated for transmission data according to the LRB format. When a sub frame #2 is transmitted, the same resource allocation method (LRB) as the head sub frame is used and the transmission data is allocated for the same RB. When a sub frame #3 is transmitted, the resource allocation method is switched from the sub frame #1 and the sub frame #2 and the transmission data is allocated for RB by using the DRB format.

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： A base station apparatus wherein the interference suppression symbol combination can be performed in a case of using the repetition technique in a multicarrier communication. In a base station (100), a repetition part (103) repeats or copies each of data symbols received from a modulating part (102) to create a plurality of same data symbols. A phase rotating part (106) imparts, in accordance with a phase rotation angle set by a setting part (107), phase rotations to the pilot and data symbols received from a multiplexing part (105). At this moment, the phase rotating part (106) imparts the phase rotations of the same angle to the pilot and data symbols assigned to the same subcarrier. Further, the phase rotating part (106) causes the phase rotation difference between the same data symbols in a cell to be different from the phase rotation difference between the same symbols in an adjacent cell.

摘要： A radio receiver apparatus and a radio transmitter apparatus wherein the energy loss caused by addition of GI is suppressed, while the reception quality is improved. A signal having been subjected to an IFFT process is repetitively transmitted N times with a length of one OFDM symbol interval. At a receiver apparatus receiving the transmitted signals, a leading data extracting part (207) extracts, from the leading data portions of the direct waves of the received signals, portions that are not interfered with by temporally adjacent data. A combing part (209) combines the received signals in such a manner that align the rear end of each repetitively transmitted data portion except the leading data portion with the rear end of the leading data portion extracted by the leading data extracting part (207). The combined signal is then subjected to an FFT process in an FFT part (210).
