Methods and apparatus for joint multi-ap transmission in wlans

A wireless transmit/receive unit (WTRU) configured to perform a multi-access point (multi-AP) communication, the WTRU comprising:

• a receiver configured to receive a first trigger frame from a first access point (AP) of a plurality of APs, the first trigger frame comprising first information, and a second trigger frame from a second AP of the plurality of APs at a predetermined time duration after receiving the first trigger frame, the second trigger frame also comprising the first information of the first trigger frame;
• a processor configured to generate a synchronization frame based on the first trigger frame and the second trigger frame, the synchronization frame comprising synchronization information;
• and
• a transmitter configured to transmit the synchronization frame to at least the first AP and the second AP;
• wherein the receiver is further configured to receive a data transmission based on the synchronization information from each of the first AP and the second AP.
