摘要： 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 (101) determines whether the delay of transport data or control information should be allowed or not. A pilot signal insertion control part (102) 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 (106) multiplexes encoded and modulated transport data with the pilot signal generated by a pilot signal generating part (105) in such a manner that realizes the placement decided by the pilot signal insertion control part (102).

摘要： Disclosed are a wireless transmission apparatus and transmission power control method which improve the error rate characteristics of data signals even when the number of streams of data signals increases, without increasing the amount of signaling. The relationship between the number of streams of data signals in each antenna (201-1, 201-2) and the data signal and pilot-signal transmission power ratio at each antenna (201-1,201-2) is stored. Specifically, a relationship where the data signal and pilot signal transmission power ratio at each antenna increases as the number of streams of data signals at each antenna increases is stored. A transmission power control unit (205) determines the data signal and pilot signal transmission power ratio on the basis of the information of the number of streams of data signals at each antenna (201-1, 201-2) that were output from a decoding unit (204), controls the transmission power of the pilot signals on the basis of the determined transmission power ratio, and outputs to a multiplexing unit (210).

The base station includes: a modulation unit (102) for modulating SCH data after being encoded; a sub carrier setting unit (105) for setting one of the sub carriers to a sub carrier (SCH sub carrier) constituting the OFDM symbol for SCH data transmission; and an IFFT unit (106) for mapping the SCH data to the sub carrier set by the sub carrier setting unit (105) among the sub carriers and performing IFFT to generate an OFDM symbol. The sub carrier setting unit (105) sets one of the sub carriers which has a frequency of a common multiple between the sub carrier interval and the cell search interval as an SCH sub carrier.

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 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.
