COMMUNICATION APPARATUS AND COMMUNICATION METHOD

Abstract:

A communication apparatus is provided that performs packet transmission at the time of detecting an interference signal. Each STA records a pair of a measurement result of an RSSI of an OBSS and a BSS Color, and reports, to an AP, BSS Colors that correspond to a maximum value and a minimum value of the RSSI. The AP generates a database or a table by using a STA having a minimum or maximum RSSI for each of the OBSS's. When a signal of an OBSS is detected, the AP selects a STA that has the smallest RSSI of the OBSS or does not have the largest RSSI of the OBSS, and performs SR transmission. Alternatively, the AP measures angles of arrival of STAs and OBSS's. When a signal of an OBSS is detected, the AP selects a STA that is most different in the angle of arrival from the OBSS or is not most similar in the angle of arrival to the OBSS, and performs SR transmission.
