Abstract
Embodiments of a system and method for communicating according to an IEEE 802.11 standard or a WiGig specification. The method includes identifying a message that requires a response from another station in less than a threshold amount of time, and that the other station cannot likely respond to within a point coordination function (PCF) interframe sequence (PIFS). The message also includes setting a reverse direction (RD) response time field in a header of an MPDU corresponding to the message to a value indicating that a response from the other station is not required within a short interframe sequence (SIFS).
