Abstract
Aspects of the present disclosure generally relate to enhanced multi-user (MU) uplink (UL) protocols in wireless networks that allow non-UL transmissions to be performed simultaneously with triggered MU UL transmissions. A station may send a trigger frame triggering MU transmissions with an appropriate signaling to allow non-UL transmissions, i.e. transmission to another station, in a resource unit of the MU transmission. Examples of non-UL transmissions include Direct Link transmissions as well as downlink (DL) transmissions. The present disclosure regards how the MAC/PHY interface at an AP and at non-AP stations can be modified to efficiently handle the DiL and DL transmissions. On one hand, a non-AP station recipient of DiL or DL transmissions can use an 802.11ax TRIGVECTOR to efficiently configure its PHY. On the other hand, the AP can configure its PHY to filter out the DiL/DL RUs.
