Symmetric transmit opportunity (TXOP) truncation (STT) including receiving a frame that truncates a TXOP around a first station, and responsive to receiving the frame, sending a second frame that truncates the TXOP around a second station. By transmitting a second frame that repeats the truncation of the TXOP transmitted from the first station, a hidden node problem can be avoided and equitable access to the medium provided by ensuring that stations that may be outside the broadcast range of the first station also receive the frame truncating the TXOP. Also disclosed is an access point (AP) that receives an extended interframe space (EIFS) set frame responsively transmits a second frame having a completed transmission corresponding to time based on an interval of EIFS less DIFS, the interval commencing from an end of the EIFS set frame.
