First Claim
1. A wireless communication device comprising:
- a processor coupled to a memory with instructions thereon, wherein the instructions, when executed by the processor, are configured to;
transmit, via a plurality of sub-carriers, a first orthogonal frequency division multiple access (OFDMA) frame to a first other wireless communication device and a second other wireless communication device, wherein the first OFDMA frame specifies a scheduled response time and a first cluster that includes a first subset of sub-carriers of the plurality of sub-carriers for use by the first other wireless communication device and a second cluster that includes a second subset of sub-carriers of the plurality of sub-carriers for use by the second other wireless communication device when the first other wireless communication device and the second other wireless communication device simultaneously transmit a second OFDMA frame to the wireless communication device during the scheduled response time; and
receive, during the scheduled response time, the second OFDMA frame from the first other wireless communication device and the second other wireless communication device, wherein the second OFDMA frame includes a first response to the first OFDMA frame from the first other wireless communication device that is transmitted within the first cluster that includes the first subset of sub-carriers of the plurality of sub-carriers specified in the first OFDMA frame and includes a second response to the first OFDMA frame from the second other wireless communication device that is simultaneously transmitted within the second cluster that includes the second subset of sub-carriers of the plurality of sub-carriers specified in the first OFDMA frame.

Abstract
Acknowledgment and/or receiver recovery mechanisms for scheduled responses within multiple user, multiple access, and/or MIMO wireless communications. Explicit scheduling information is provided from a first wireless communication device (e.g., an access point (AP), a transmitting wireless communication device) to a number of other wireless communication devices (e.g., wireless stations (STAs), receiving wireless communication devices) directing those other wireless communication devices a manner by which responses (e.g., acknowledgments (ACKs), block acknowledgments (BACKs), training feedback frames, etc.) are to be provided to the first wireless communication device there from. Such direction may include the order, timing, cluster assignment, etc. by which each respective wireless communication device is to provide its respective response to the first wireless communication device. In the event of the first wireless communication device failing to receive at least one response from at least one of the other wireless communication devices, various communication medium recovery mechanisms may be performed.
