No. 13/247,086 [Attorney Docket No. 102994U4, titled “SYSTEMS AND METHODS FOR COMMUNICATION OF CHANNEL STATE INFORMATION,” filed Sep. 28, 2011, U.S. application Ser. No. 13/247,100 [Attorney Docket No. 103221U1, titled “SYSTEMS, METHODS AND APPARATUS FOR DETERMINING CONTROL FIELD AND MODULATION CODING SCHEME INFORMATION,” filed on Sep. 28, 2011, and U.S. application Ser. No. 13/247,124 [Attorney Docket No. 103221U2, titled “SYSTEMS, METHODS AND APPARATUS FOR DETERMINING CONTROL FIELD AND MODULATION CODING SCHEME INFORMATION,” filed Sep. 28, 2011, each of which are incorporated herein by reference, in their entirety.
The various operations of methods described above may be performed by any suitable means capable of performing the corresponding functions. The means may include various hardware and/or software component(s) and/or module(s), including, but not limited to a circuit, an application specific integrate circuit (ASIC), or processor. Generally, where there are operations, module, or steps illustrated in Figures, those operations may have corresponding counterpart means-plus-function components. For example, an access point may comprise means for receiving a frame comprising an indicator signifying that the frame is unsolicited, the frame further comprising first and second fields, means for identifying a most recent communication having fields that match the first and second fields, means for determining a modulation coding scheme (MC S) based at least on the identified communication and the received indicator, and means for transmitting data indicative of the determined MCS. In another example, an access point may comprise means for receiving a frame, means for determining a type of the frame, means for determining a modulation coding scheme (MCS) based at least on the determined frame type, and means for transmitting data indicative of the determined MCS.
identifying a most recent communication having fields that match the first and second fields; and
determining a modulation coding scheme (MCS) based at least on the identified communication and the received indicator.
a receiver configured to receive a frame comprising an indicator signifying that the frame is unsolicited, the frame further comprising first and second fields; and
determine a modulation coding scheme (MCS) based at least on the identified communication and the received indicator.
means for identifying a most recent communication having fields that match the first and second fields; and
means for determining a modulation coding scheme (MCS) based at least on the identified communication and the received indicator.
13. A computer program product for wirelessly communicating comprising a non-transitory computer readable medium comprising instructions that when executed cause an apparatus to:
a receiver configured to receive, via the antenna, a frame comprising an indicator signifying that the frame is unsolicited, the frame further comprising first and second fields; and
