Patent ID: 10129876

Abstract:
This disclosure describes methods, apparatuses, and systems related to network allocation vectors. A device is disclosed that may determine a first length of time corresponding to a first spatial reuse transmit opportunity (SR-TxOP) time period. The device may determine a second length of time corresponding to a transmit opportunity (TxOP) time period that starts when a request to send (RTS) frame is transmitted and ends after the first length of time ends. The device may cause to transmit the RTS frame, over the channel, to a first device. The device may determine that a clear to send (CTS) frame is received from the first device, the CTS frame comprising a first duration field equal to having a third length of time corresponding to a second transmission opportunity (SR-TxOP). The device may determine that the third length of time corresponds to a length of time between when the CTS frame was transmitted and when the first length of time ends. The device may determine that the third length of time is less than the second length of time. The device may cause to transmit a CTS to self frame, over the channel, comprising a second duration field equal to having a fourth length of time, wherein the fourth length of time corresponds to a length of time between when the CTS to self frame is transmitted and when the first length of time ends.
