Abstract: Embodiments disclosed herein are directed to communicating time-critical ultra-low latency (ULL) data. An access point station (AP) communicates time-critical ULL data using aggregated MAC Protocol Data Unit (A-MPDU) preemption. When time-critical ULL data for a second associated STA (STA2) becomes available at a medium access control (MAC) layer of the AP during transmission of a physical layer protocol data unit (PPDU) to a first associate station (STA1), the AP may encode the time-critical ULL data in a new A-MPDU subframe for insertion before one of the A-MPDU subframes of the PPDU that has not yet been transmitted. The new A-MPDU subframe may be encoded to include zero-padding to set a size of the new A-MPDU subframe equal to a size of the A-MPDU subframe that has been preempted. The A-MPDU subframes 606 for STA1 may be encoded include a MAC address of the STA1 and the new A-MPDU subframe 608 may be encoded include a MAC address of the STA2.

Abstract: An access point station (AP) communicates with a plurality of non-AP stations (STAs) within a synchronized transmission opportunity (S-TXOP). The S-TXOP may comprise an S-TXOP trigger followed by a plurality of S-TXOP slots. After transmission of the S-TXOP trigger, the AP may encode, for transmission within an S-TXOP slot, a downlink (DL) multi-user physical layer protocol data unit (DL MU-PPDU). The DL MU-PPDU may include a preamble followed by a data field. To indicate that a previously signaled resource unit (RU) allocation is to be used during the S-TXOP slot, the AP may encode the preamble to include an allocation ID of the previously signaled RU allocation in a signal field (SIG) of the preamble and to include a SIG-2 presence indicator to indicate that a second signal field (SIG-2) is not included in the preamble.

Abstract: Embodiments of a wireless network and method for communicating aggregated packets are generally described herein. In some embodiments, an aggregation header frame that identifies the originator is included in an aggregation of media-access control (MAC) frames to allow the originator to be easily identified when none of the MAC frames are properly received.
