ACCESS POINT (AP)-AIDED DOWNLINK TRANSMISSION OPPORTUNITY (TXOP) PREEMPTION BY STATIONS (STAS) WITH LOW-LATENCY UPLINK TRAFFIC
Abstract: this disclosure provides methods, components, devices and systems for access point (ap)-aided downlink transmission opportunity (txop) preemption by stations (stas) with low-latency uplink traffic. some aspects more specifically relate to how a sta transmits a preemption indication (pri) associated with a signature of the sta and how an ap, via reception of signature-based pris, may obtain information relating to which specific stas have low-latency traffic ready for uplink transmission. such signatures may relate to a resource allocation, such as a tone pattern, used to transmit at least a portion of a pri. in some examples, the ap transmits a preemption scheduling (prs) frame that includes channel access information, for each of the sta(s) that sent a pri, associated with a downlink txop of the ap. such channel access information may include at least a grant of permission for sta(s) to attempt uplink preemption of the downlink txop.
