Wireless communication apparatus and wireless communication method
First Claim
1. A wireless communication apparatus using a frequency hopping scheme, which performs wireless communication with a different wireless communication apparatus by using a plurality of frequency bands, comprising:
- an interference measurer configured to measure interference quantities showing strength of interference signals in respective frequency bands;
a hopping pattern storage configured to store a plurality of hopping patterns each having hopping densities set for the respective frequency bands, the hopping densities being a number of times that transmission is performed per unit time in the respective frequency bands, the number of times being larger than 0;
a hopping pattern selector configured to select a hopping pattern from the hopping pattern storage on the basis of the interference quantities in the respective frequency bands;
a hopping pattern notifier configured to notify the different wireless communication apparatus of the selected hopping pattern; and
a communicator configured to communicate with the different wireless communication apparatus by using the selected hopping pattern,wherein the hopping pattern selector selects the hopping pattern which has a first hopping density for frequency bands where an interference quantity is not greater than a threshold, and which has a second hopping density less than the first hopping density for frequency bands where an interference quantity is more than the threshold.
