Abstract
In some aspects, the disclosure is directed to methods and systems for extending a range of wireless communication. In one aspect, a first station device from one or more stations receives a trigger frame comprising a predetermined bit from an access point. The first station device may transmit to the access point a first response message in a first format during a first time period, in response to detecting the predetermined bit in the trigger frame. The first station device may transmit to the access point, a second response message in a second format during a second time period, in response to detecting the predetermined bit in the trigger frame. The first station device may receive, from the access point, a downlink frame during a third time period after the first time period and the second time period.
