Abstract:
A base station apparatus (100) has: a generation unit (101-1, 101-2) that generates a signal to be transmitted in a first frequency region included in a frequency band of one wireless carrier signal; an adjustment unit (102-1, 102-2) that adjusts, on a per-symbol basis, the gain of the signal generated by the generation unit (101-1, 101-2); a transmission unit (105) that transmits a signal obtained by gain adjustment by the adjustment unit (102-1, 102-2); a reception unit (106) that receives a signal in a second frequency region included in the frequency band of the wireless carrier signal; and a control unit (109) that, on the basis of a symbol arrangement for a downstream wireless channel and an upstream wireless channel in the first frequency region and the second frequency region, determines an adjustment symbol to be subjected to gain adjustment, and decreases or increases the gain of the determined adjustment symbol compared with other symbols.
