ACTIVATION FRAME TRANSMISSION METHOD, COMMUNICATION DEVICE, AND CHIP

Abstract

The invention relates to the field of wireless communication and applies to wireless local area networks that support the 802.11be standard. Specifically, the invention relates to a method for indicating spatial reuse parameters in an activation frame and a corresponding method for determining the spatial reuse parameter field in a physical layer protocol data unit (PPDU), and the associated equipment. This method comprises the following steps: The access point (AP) sends an activation frame, wherein the activation frame is used to activate the station to send an ultra-high traffic trigger based on the EHT TB PPDU physical layer protocol data unit.The station determines, based on one or two of the values ​​indicated by the spatial reuse parameter EHT uplink UL EHT SRP and the value indicated by one or more spatial reuse parameter fields of the uplink UL SRP in the general information field of the trigger frame, the value indicated by the spatial reuse parameter SRP in the universal signal field U-SIG of the EHT TB PPDU. The STA sends the EHT TB PPDU to the AP. In the implementation of this scheme of the invention, the spatial reuse parameter field of the EHT TB PPDU can be set without changing the frame structure of the U-SIG. The invention also relates to a method of transmitting the trigger frame, a communication device, and a chip.
