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.

Abstract: Methods and apparatuses are provided for operating a Machine-to-Machine (M2M) Subscriber Station (SS) for a time-controlled service in an M2M communication system. The M2M SS registers the time-controlled service. The M2M SS establishes a service flow with an M2M Base Station (BS), after registering the time-controlled service. Data is transferred, from the M2M SS, to the M2M BS, through the service flow during an access admission time period. Transmission of the data to the M2M BS is ceased during an access restriction time period.
