1. A method of multi-access point (multi-AP) communication performed by a wireless transmit/receive unit (WTRU), the method comprising:
receiving, from a first access point (AP) of a plurality of APs, a trigger frame comprising an identifier of the first AP and an identifier of a second AP of the plurality of APs;
generating an inverse trigger frame, the inverse trigger frame comprising the identifier of the first AP, the identifier of the second AP, and synchronization information;
transmitting, to at least the first AP and the second AP, the inverse trigger frame; and
receiving respective data transmissions from the first AP and the second AP based on the synchronization information.
