WebIf CCA busy primitive is detected, a STA processes the received information; the STA sets their ProbeTimer to MaxChannelTime if it receives messages with implicit or explicit evidence of APs’ existence, including data frames, management frames (association, authentication, etc.), and control frames (CF-End, CF-End+ACK frames, PS-poll, etc.) WebIf CCA reports that the channel has gone busy, the station is forced to suspend its arbitration until CCA reports that the channel is idle again. How Co-Channel Interference Reduces WLAN Performance CCI is simply the assertion of NAV due to detection of an Layer 1 or Layer 2 duration field by the radio.
