Abstract
A wireless protocol allowing an AP to allocate time within a transmit opportunity (TXOP) to non-AP stations. The allocations are made under condition that the non-AP STA(s) will satisfy Access Class (AC) requirements communicated in a frame sent by the AP STA, such as within an MU RTS TXS Trigger frame. Upon receiving the frame, the non-AP responds on whether it can meet the conditions, such as within a Clear-To-Send (CTS) message. If the non-AP can meet the conditions, then it proceeds to transmit data (to the AP, or a peer non-AP). Otherwise, if it cannot meet the conditions, then the AP can communicate the allocation to another non-AP STA. There are also conditions for how the non-AP can aggregate data units into A-MSDUs.
