Wireless access points, stations, and communication methods

Abstract

The invention relates to an access point (AP), a station (STA), and a method of wireless communication. This wireless communication method involves a transmission step, using an AP, a Multi-User Ready-To-Send (MU-RTS) request frame to multiple STA stations, where the MU-RTS frame indicates whether a Clear-To-Send (CTS) response frame has been transmitted by each of the multiple STA stations on the primary 20 MHz (P20), primary 40 MHz (P40), primary 80 MHz (P80), primary 160 MHz (P160), or 320 MHz channel. and at least one 20 MHz channel is perforated within the P80, P160, or 320 MHz channel. These modifications can address known technical issues, improve Transmit Opportunity (TXOP) protection, perform MU-RTS / CTS response frame exchange to effectively protect TXOP, achieve extremely high transmission yields, generate good communication performance, and / or generate high reliability.
