Method for indicating uplink bandwidth in physical layer protocol data units, communication equipment, and computer-readable storage media

Abstract

The invention relates to a wireless communication medium, for example, applicable to a wireless local area network supporting the 802.1 IBE standard, and specifically to a method for indicating uplink bandwidth PPDU (physical layer protocol data unit), a communication device, and a computer-readable storage medium. This method comprises the following steps: AP (access point) creates and sends an activation frame. This trigger frame carries a first indicator, where the first indicator is used directly to indicate or indicate the general EHT TB PPĐU (extremcly high throughput trigger-based physical layer protocol data unit) bandwidth or the total uplink PPDL transmission bandwidth. The trigger frame carries a second indicator, which is used to indicate the distribution of HE TB PPDU (High Efficient Trigger Based Physical Layer Protocol Data Unit) and / or EHT Γ ΓB PPDU within the total uplink PPDU transmission bandwidth, or to directly indicate whether the EHT station transmits HE TB PPDU or EHT TB PPDU. According to the patent options, the activation frame is capable of activating the EHT station to perform uplink data transmission on a bandwidth greater than 160 MHz while ensuring the compatibility of the activation frame.
