Multiplexing clients of different generations in trigger-based transmissions
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiplexing clients of different generations in trigger-based transmissions, including trigger-based transmissions in extremely-high throughput (EHT) Wi-Fi systems. An access point (AP) may generate a trigger frame compatible with two types of stations (STAs), such as EHT STAs and legacy (or high efficiency (HE)) STAs. The AP may transmit the trigger frame to a group of STAs, where legacy STAs may process the trigger frame a legacy trigger frame. EHT STAs may process the trigger frame to determine resource unit (RU) allocations for uplink transmissions in a bandwidth greater than a legacy bandwidth. An EHT STA may determine the resources in the larger bandwidth based on an EHT RU allocation table, a legacy RU allocation table and an additional bit in the trigger frame, or an ordering of RU allocations in the trigger frame.
