MAC/PHY interface of wireless stations compatible with direct link and downlink transmissions in trigger-based multi-user transmissions

摘要

Aspects of the present disclosure generally relate to an enhanced multi-user (MU) uplink (UL) protocol in a wireless network that allows non-UL transmission to be performed concurrently with a triggered MU UL transmission. The station, in the resource unit of the MU transmission, may transmit a trigger frame that triggers the MU transmission with appropriate signaling to allow non-UL transmission, that is, transmission to another station. Examples of non-UL transmission include downlink (DL) transmission as well as direct link transmission. This disclosure relates to how the MAC/PHY interface in AP and non-AP stations can be modified to efficiently handle DiL and DL transmissions. On the one hand, the receiver of the non-AP station of DiL or DL transmission can efficiently configure its PHY using 802.11ax TRIGVECTOR. On the other hand, the AP can configure the PHY to filter out the DiL/DL RU.
