Claim 0:
1. An access point (AP) device for soliciting one or more channel status responses, the AP device comprising storage and processing circuitry, the processing circuitry coupled to storage, the processing circuitry configured to:
determine, by the AP device, a plurality of user devices associated with a multiuser communication over a wireless channel, wherein the wireless channel is associated with a plurality of subcarrier frequencies;
assign, by the AP device, a first subset of subcarrier frequencies to a first user device of the plurality of user devices, wherein the first subset is associated with a first subcarrier frequency;
assign, by the AP device, a second subset of subcarrier frequencies to a second user device of the plurality of user devices, wherein the second subset is associated with a second subcarrier frequency;
cause to send, by the AP device, a channel status request poll to the plurality of user devices, wherein the channel status request poll comprises a first indication of a first time period for the plurality of user devices to simultaneously transmit their respective channel status response uplink to the AP device, a second indication of the first subcarrier frequency for the first user device to transmit a first channel status response, and a third indication of the second subcarrier frequency for the second user device to transmit a second channel status response;
identify, by the AP device, the first channel status response received from the first user device over the first subset of subcarrier frequencies during the first time period;
determine, by the AP device, based on the first channel status response received from the first user device by the AP device, that a quantity of data that the first user device is to transmit uplink to the AP device after the first user device has transmitted the first channel status response to the AP device is greater than a data threshold;
determine, by the AP device, based on a first signal strength being greater than a threshold signal strength greater than zero and based on the quantity of data being greater than the data threshold, that the first user device is ready for data communication, wherein the first signal strength is associated with the first channel status response and the first subcarrier frequency;
identify, by the AP device, the second channel status response received from the second user device over the second subset of subcarrier frequencies during the first time period; and
determine, by the AP device, based on a second signal strength being greater than the threshold signal strength, that the second user device is ready for data communication, wherein the second signal strength is associated with the second channel status response and the second subcarrier frequency.
