1. A method of wireless communication, comprising:
- generating, at a first device, a control frame comprising a null data packet acknowledgement (NDP ACK) frame or NDP modified ACK frame, the NDP ACK frame or NDP modified ACK frame comprising a duration field and a duration indication field, wherein the duration indication field provides signaling information for the NDP ACK or the NDP modified ACK, wherein the NDP ACK further comprises a relayed frame field, wherein providing signaling information comprises setting the duration indication field equal to 1, setting the relayed frame field equal to 1, and setting the duration field to a non-zero value to indicate to an intended station (STA) not to transmit any data frames for a time period equal to the non-zero value; and
transmitting the control frame to a second device.

Abstract
Systems, methods, and devices for communicating short control frames are described herein. In some aspects, a method of wireless communication includes generating a control frame comprising a contention free end (CF-end) frame, the CF-end frame comprising a physical layer preamble having a type field, the type field including an indicator indicating the CF-end frame is a null data packet (NDP). The method further includes transmitting the control frame.
