Abstract: Methods, systems, and devices are described for selectively enabling legacy protection in a WLAN. A method may include receiving, by an access point, a DSSS signal from a station, and activating legacy protection within a WLAN of the access point based at least in part on the received DSSS signal. For instance when a station cannot be initially detected, the access point may transmit an OFDM signal indicating a NAV period associated with a remote station initial access period. The access point may then receive a DSSS transmission from a remote station during the remote station initial access period. A method may include receiving, at a wireless station, an indication of a NAV period associated with remote station initial access, monitoring for radio transmissions during the NAV period, and transmitting a DSSS signal during the NAV period based on the monitoring.
