RESOURCE INDICATION PROCESSING METHOD AND PROCESSING DEVICE, ACCESS POINT AND STATION

摘要

In a wireless local area network (WLAN), a TXOP comprises at least a first time interval and a second time interval located behind the first time interval therein. An access point (AP) in the WLAN transmits, at least before the first time interval, a PPDU physical layer frame header, wherein the PPDU physical layer frame header comprises information I1 for indicating whether the TXOP has an uplink trigger frame (UL trigger). The AP transmits downlink STA data at the first time interval. If the information I1 indicates that the TXOP has the UL trigger, the AP transmits, at the second time interval, the uplink trigger frame (UL trigger) comprising uplink scheduling information.
