PREEMPTION TECHNIQUES FOR LOW LATENCY DEVICES
This abstract first appeared for US patent application 20250132871 titled 'PREEMPTION TECHNIQUES FOR LOW LATENCY DEVICES
Original Abstract Submitted
this disclosure provides methods, components, devices and systems for preemption techniques for low latency devices. some aspects more specifically relate to preemption techniques to enable transmission of low latency data. in some examples, an access point (ap) may transmit a first physical layer protocol data unit (ppdu) using a dedicated resource unit (ru) and a broadcast ru. the broadcast ru may indicate information for a preemption indication, such as a resource unit within the same transmission opportunity (txop) for the preemption indication. a wireless station (sta) with pending low latency data may transmit the preemption indication via the ru indicated by the first ppdu. the preemption indication may indicate that a subsequent scheduled ppdu in the txop will be preempted for the sta to transmit a ppdu and convey the low latency data.
