Spatial-Reuse Enhancement in RTS and CTS

摘要

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.

1. A method for signaling spatial reuse using a control frame, comprising:
receiving a request to send (RTS) frame from an access point (AP), wherein the RTS frame includes a redefined field that specifies spatial reuse information; setting a network allocation vector (NAV) based at least in part on the RTS frame; receiving a second frame within a threshold duration after a Short Interframe Space (SIFS) following the RTS frame; and resetting the NAV based at least in part on receiving the second frame.
