US Patent 10034227 Access point association using trigger-based uplink single user transmission

In aspects of access point association using trigger-based uplink single user transmission, a wireless network system includes a station device that detects an initial trigger frame communicated in the wireless network system, and the station device can communicate an association request to an access point to join the wireless network system. The access point can receive the association request from the station device and generate an association response as an acknowledgement to the association request. The acknowledgement aggregates an association response frame that includes an association identifier for the station device and a unicast trigger frame to initiate a trigger-based uplink single user (UL-SU) transmission from the station device. The access point can then communicate the acknowledgement to the station device.
