Abstract: Systems, methods, and mechanisms for a sub-transmit opportunity (sub-TxOP) and/or sub-TxOPs within a transmit opportunity (e.g., TxOP) to reduce channel access delays in wireless systems, e.g., such as in current and future IEEE 802.11 systems. A wireless device (e.g., an access point or wireless station) may transmit, at a start of a TxOP to one or more wireless devices, signaling indicating that the TxOP includes one or more sub-TxOPs. The wireless device may contend, during a first contention period (CP) preceding a first sub-TxOP of the one or more sub-TxOPs, for access to a medium. The wireless device may transmit, upon determining that the wireless device can transmit in the first sub-TxOP, data to at least one wireless device of the one or more wireless devices.

Abstract: A second electronic device that receives a frame is described. This second electronic device includes: an antenna node communicatively coupled to an antenna; and a second interface circuit, communicatively coupled to the antenna node, that communicates with an electronic device. During operation the second interface circuit receives, associated with the electronic device, the frame that includes an indication that the electronic device uses a frame-based equipment (FBE) channel access technique and attributes of the FBE channel access technique. The attributes include: a duration of the FBE channel access technique, and a fixed frame period (FFP) for communication during the FBE channel access technique. Moreover, the frame is compatible with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.
