METHODS FOR EFFICIENT ACKNOWLEDGEMENT IN WIRELESS SYSTEMS
First Claim
1. An Access Point (AP) configured to receive an uplink orthogonal frequency division multiple access based block acknowledgement response in an 802.11 based wireless network, the AP comprising:
- a transceiver configured to transmit a downlink allocation to the plurality of mobile devices, wherein an order of a plurality of mobile devices in the downlink allocation indicates respective uplink resource assignments; and
processing circuitry configured to identify uplink resources as a function of the order of the plurality of mobile devices in the downlink allocation.

Abstract
An AP receives, from one or more STAs, an uplink orthogonal frequency division multiple access based block acknowledgement response in an 802.11 based wireless network. The AP transmits the downlink allocation for the downlink frame to the plurality of mobile devices, wherein the order of the plurality of mobile devices in the downlink allocation indicates respective uplink resource assignments. The STA receives a downlink frame with an allocation comprising the listing of a plurality of mobile devices for which data is transmitted in the downlink frame. The STA identifies an uplink resource allocation as a function of a location of a first mobile device within the listing of the plurality of mobile devices. The STA then transmits an acknowledgment on the uplink resource allocation corresponding to the location of a first mobile device within the listing of the plurality of mobile devices.
