Abstract: Methods, devices, and computer program products for improving training field design in packets with increased symbol durations are disclosed. In one aspect, a method of transmitting a packet on a wireless communication network is disclosed. The method includes transmitting a preamble of the packet over one or more space-time-streams, the preamble including one or more training fields configured to be used for channel estimation, the one or more training fields each comprising one or more symbols of a first symbol duration. The method further includes transmitting a payload of the packet over the one or more space-time-streams, the payload comprising one or more symbols of a second symbol duration, the second symbol duration greater than the first symbol duration.

Abstract: Systems, methods, and devices for high-efficiency wireless frequency division multiplexing are provided. A method includes exchanging, at an access point, at least one frame reserving a wireless medium with at least one of a first and second wireless device. The method further includes receiving a first communication on a first set of wireless frequencies from the first wireless device. The method further includes receiving a second communication, at least partially concurrent with the first communication, on a second set of wireless frequencies from the second wireless device. The method further includes transmitting at least one acknowledgment of the first and second communication. The first set and the second set are mutually exclusive subsets of a set of wireless frequencies available for use by both the first and second wireless device.

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.
