1. A wireless station comprising:
sending and receiving circuitry to receive data frames sent from another wireless station, the received data frames including a first data frame to be relayed to a further wireless station, the first data frame being referred to as a relay target;
interference time storage circuitry to store an interference time that is a time from when the sending and receiving circuitry starts receiving each of the data frames to when the sending and receiving circuitry terminates receiving the data frames;
waiting time determination circuitry to determine a waiting time on a basis of the interference time;
frame generation circuitry to generate a second data frame by changing a destination of the first data frame to a data aggregation station that aggregates the data frames or to a wireless station that serves as a relay destination; and
transmission control circuitry to wait for the waiting time and cause the sending and receiving circuitry to send the second data frame.
