In addition, the distance includes a difference between the distance between STA 200-1 #1 and AP 100-1 #1 and a distance between the self-device and STA 200-1 #1. Therefore, it is possible to lower a possibility of an influence of the transmission of STA 200-1 #1 on the communication in the other BSS.
In addition, the information obtained in the reception of the PHY header and used to control the transmission power includes at least one of the modulation scheme information, transmission power information, and the allowance signal information included in the PHY header and reception signal strength in regard to the PHY header. Therefore, in a case in which all the pieces of information are included, it is possible to improve accuracy of the process of controlling the transmission power. Conversely, even in a case in which some of the pieces of information are deficient, for example, a value stored in advance can be used for the deficient information to execute the process of controlling the transmission power.
In addition, in a case in which the transmission power requested from AP 100-1 #2 which is a destination of a signal to be transmitted by the self-device is equal to or less than the decided transmission power, STA 200-1 #2 transmits the signal with the requested transmission power. Therefore, by transmitting the signal with only transmission power which rarely affects the communication of the other BSS while satisfying a request from AP 100-1 #2, it is possible to suppress disturbance of the communication of the other BSS while maintaining the reception success ratio.
