Spatial-reuse enhancement in RTS and CTS
Disclosed herein are system, method, and computer program product embodiments for enabling a spatial reuse opportunity at a high efficiency (HE) station and a network allocation vector (NAV) reset capability at a legacy station using a Request to Send and/or Clear to Send (RTS and/or CTS) frame. For example, the method can include receiving a RTS frame with a redefined field that specifies spatial reuse information. The NAV can be set based on the RTS frame. The method can determine whether a second frame was received within a threshold time after a Short Interframe Space (SIFS). Finally, the method can reset the NAV based on whether the second frame was received within the threshold time.
