METHOD FOR INDICATING UPLINK BANDWIDTH IN PHYSICAL LAYER PROTOCOL DATA UNITS, COMMUNICATION EQUIPMENT, AND COMPUTER-READABLE STORAGE MEDIA

Abstract

This article discusses the field of wireless communication, for example, its application to wireless local area networks supporting the 802.1 1BE standard, and specifically, refers to the method of indicating uplink bandwidth PPDU (physical layer protocol data unit), communication devices and storage media that can be read by a computer. This method includes the following steps: The AP (access point) creates and sends an activation frame. This activation frame carries the first indicator information, which is used directly to indicate either the overall bandwidth EHT TB PPDU (extremely high throughput trigger-based physical layer protocol data unit) or the total uplink PPDU bandwidth. The activation frame carries the second indicator information...In this case, the second trigger information is used to indicate the distribution of the HETB PPDU (High Efficiency Trigger Based Physical Layer Protocol Data Unit) and / or EHT TB PPDU over the uplink PPDU transmission bandwidth, or to directly indicate whether the EHT station transmits HETB PPDU or EHT TB PPDU. According to the invention's options, the trigger frame is capable of triggering the EHT station to perform uplink data transmission over a bandwidth greater than 160 Mbps while still ensuring the compatibility of the trigger frame.
