Abstract
Various embodiments of symmetric transmit opportunity (TXOP) truncation (STT) systems and methods are disclosed. One method embodiment, among others, comprises 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. Others system and method embodiments are disclosed.
Claims20
A symmetric transmit opportunity (TXOP) truncation method between a first station and a second station, comprising:
- receiving, at the second station, a first frame from the first station;
- receiving, at the second station, an extended interframe space (EIFS) set frame after the first frame from the first station, wherein the EIFS set frame includes a PHY header and a preamble without a MAC payload;
- and
- sending, from the second station, a second frame having a completed transmission corresponding to time based on an interval of EIFS less distributed coordinate function interframe space (DIFS), the interval commencing from an end of the first frame.
A station comprising:
- a receiver of the station configured to receive a first frame from a first station and to receive an extended interframe space (EIFS) set frame after the first frame from the first station, wherein the EIFS set frame includes a PHY header and a preamble without a MAC payload;
- and
- a transmitter of the station configured to send 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 first frame.
A non-transitory, computer-readable medium having instructions stored there-on for performing a symmetric transmit opportunity (TXOP) truncation between a first station and a second station, the instructions comprising:
- instructions for receiving from a first station a first frame;
- instructions for receiving from the first station an extended interframe space (EIFS) set frame after the first frame, wherein the EIFS set frame includes a PHY header and a preamble without a MAC payload;
- and
- instructions for sending, based upon a faulty frame check sequence (FCS), at a second station 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 first frame.
A symmetric transmit opportunity (TXOP) truncation method between a first station and a second station, comprising:
- receiving from the first station a first frame addressed at the second station;
- and
- sending at the second station an extended interframe space (EIFS) set frame after receiving the first frame, wherein the EIFS set frame includes a PHY header and a preamble without a MAC payload.
