Patent ID: 11070330

Abstract:
A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. The WDEV supports first communications with another WDEV to determine an agreed-upon orthogonal frequency division multiple access (OFDMA) resource unit (RU) and agreed-upon OFDMA sub-carriers, adjacent or interspersed, to be used by the other WDEV to provide predetermined response(s). The WDEV then transmits a question to the WDEV and processes the plurality of agreed-upon OFDMA sub-carriers within the OFDMA RU to determine whether energy therein indicates a response of the one or more predetermined responses to the question being received from the other WDEV in accordance with second communications.
