Acknowledgment and/or receiver recovery mechanisms for scheduled responses within multiple user, multiple access, and/or MIMO wireless communications

摘要

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.

1. A wireless communication device comprising:
a communication interface; and a processor, at least one of the processor or the communication interface configured to:
generate a first frame that includes first data for a plurality of other wireless communication devices, wherein a first portion of the first data is for a first other wireless communication device and a second portion of first data is for a second other wireless communication device, wherein the first frame includes a scheduled response time for the plurality of other wireless communication devices to transmit a plurality of responses simultaneously to the wireless communication device, wherein the first frame also includes information to direct the first other wireless communication device to provide a first response using a first cluster during a first time period and to direct the second other wireless communication device to provide a second response using a second cluster during a second time period;transmit the first frame to the plurality of other wireless communication devices;receive, in response to the first frame and simultaneously at the scheduled response time, at least two of the plurality of responses respectively from at least two wireless communication devices of the plurality of other wireless communication devices, wherein a first of the plurality of responses is received from a first of the plurality of other wireless communication devices and a second of the plurality of responses is received from a second of the plurality of other wireless communication devices, wherein the at least two of the plurality of responses include at least one of an acknowledgement (ACK), a block acknowledgement (BA), or a training feedback frame;generate a second frame that includes second data for at least one wireless communication device of the plurality of other wireless communication devices from which no response has been received in response to the first frame;transmit the second frame to the at least one wireless communication device of the plurality of other wireless communication devices; andreceive, in response to the second frame, another response from the at least one wireless communication device of the plurality of other wireless communication devices.
