Signaling and feedback schemes of time-vary channels in high-efficiency WLAN
Signaling and feedback schemes of channel variation information from WLAN receiver are proposed. WLAN receiver performs channel tracking and obtains channel variation information. The signaling and feedback of channel variation information can help WLAN transmitter to decide when to apply travelling pilots or mid-amble in the transmission. Furthermore, the channel variation information can assist WLAN transmitter for scheduling the next transmission properly and thereby enhancing the system performance of WLAN.
