Patent ID: 11930493

Abstract:
This application relates to the wireless communications field, is applied to, for example, a wireless local area network supporting the 802.11 be standard Methods and apparatuses for indicating an uplink parameter of a physical layer protocol data unit (PPDU) are described. In an example method, an access point (AP) generates and sends a trigger frame, where the trigger frame includes an uplink length field. The uplink length field is used to indicate lengths indicated by legacy signal (L-SIG) fields in a high efficient trigger based (HE TB) PPDU and an extremely high throughput (EHT) PPDU, or the uplink length field is used to indicate the length indicated by the L-SIG field in the EHT PPDU. A length value indicated by the uplink length field is a positive integer and is a multiple of 3 minus 2.
