    Abstract: A method of wirelessly communicating a packet including a first portion for transmission over at least one channel of a first transmission type and a second portion for transmission over at least one channel of a second transmission type. In one aspect, the method includes generating, at a wireless device, a packet including a first portion having a first symbol duration. The packet further includes a second portion having a second symbol duration greater than the first. The second portion can include a plurality of repeated portions of the signal field, the repeated portions having the second symbol duration. The first portion includes a first training field. The method further includes prepending or appending a second training field to the first portion. The second training field has the second symbol duration. The method further includes transmitting the packet.

    Abstract: A method for high efficiency wireless communication is provided. In one aspect, a method of high efficiency wireless communication includes generating, at an access point, a message for transmission over at least one channel. The message includes a first signal field indicative of a length of the first message after the first signal field. The message further includes a second signal field indicative of at least one channel assignment. The second signal field has a length based on a minimum allocation size. The method further includes transmitting the message to one or more wireless devices.

    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: A method includes sending, from an access point of a wireless network to a first station of a plurality of stations of the wireless network, a packet including a preamble, a data portion, and trigger data that includes non-precoded, omni-direction data. The preamble precedes the data portion. The data portion precedes the trigger data. The trigger data is configured to cause the first station to perform a channel measurement responsive to receiving the packet. The access point sends beamformed data to one or more of the plurality of stations. At least one of the plurality of stations includes a mobile station configured to receive the beamformed data. The method also includes receiving, at the access point from the first station, feedback information that includes channel state information associated with the trigger data. The feedback information is received from the first station without polling individual stations of the plurality of stations.
