An 802.11ax Station indicates support for PSR based spatial reuse transmission by setting the PSR based SR Support subfield to 1 in the HE PHY capabilities information element.
An 802.11ax Station indicates support for PSR based spatial reuse reception by setting the PSR responder subfield to 1 in the HE MAC capabilities Information field in the HE Capabilities Information element
The HE Capabilities Information element and snippets of the HE MAC Capabilities element subfield and HE PHY Capabilities element subfield are provided below which depicts the parameters to be set for PSR based transmission and reception.
