AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 1, 2, 9 and 10 is confirmed.
Claims 3-8 and 11-16 were not reexamined.
1. A method for transmitting a response frame in a wireless network, the method comprising:
receiving, by a wireless device, a downlink frame from an access point;
identifying, by the wireless device, scheduling information in the downlink frame, the scheduling information soliciting an uplink response frame from the wireless device;
in response to the scheduling information being located in a Media Access Control (MAC) header in the downlink frame, generating, by the wireless device based on the scheduling information, the uplink response frame responsive to the downlink frame, the uplink response frame including only a single high efficiency long training field (HE-LTF) that consists of a single orthogonal frequency-division multiplexing (OFDM) symbol; and
transmitting, by the wireless device to the access point, the uplink response frame using the scheduling information.
