Methods and systems for frequency multiplexed communication in dense wireless environments
First Claim
1. A method of high-efficiency wireless frequency division multiplexing, comprising:
- receiving, at a first wireless device, a reference signal from an associated access point, the reference signal indicative of a time of joint transmission with at least a second wireless device and a deferral time for third party devices, the reference signal comprising one or more station information fields, a frame check sequence (FCS), and one or more padding bits between a final station information field and the FCS, the reference signal only being sent on a primary channel with an indication that only idle channels are to be used; and
transmitting a first communication to the associated access point based on the reference signal, the first communication utilizing a first subset of wireless frequencies and being concurrent with a second communication from the second wireless device, the second communication utilizing a second subset of wireless frequencies, the second subset of wireless frequencies excluding the first subset of wireless frequencies.

Abstract
Systems, methods, and devices for high-efficiency wireless frequency division multiplexing are provided. A method includes receiving, at a first wireless device, a reference signal from an associated access point, the reference signal indicative of a time of joint transmission with at least a second wireless device. The method further includes transmitting a first communication to the access point based on the reference signal, the communication utilizing a first subset of wireless frequencies available for use. The first communication is concurrent with a second communication, from the second wireless device, utilizing a second subset of wireless frequencies, the second subset excluding the first subset.
