Patent ID: 10003441

Abstract:
A wireless communication device (alternatively, device, WDEV, etc.) includes a 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 a 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. A WDEV selects a resource unit (RU) from an orthogonal frequency division multiple access (OFDMA) sub-carrier plan for use in supporting communications with another WDEV. The WDEV transmits a signal to the other WDEV that includes information that specifies the RU that is selected from the OFDMA sub-carrier plan and then supports communications with the other WDEV using the RU that is selected from the OFDMA sub-carrier plan. The OFDMA sub-carrier plan includes multiple OFDMA sub-carrier sub-plans of different sized RUs and null sub-carriers.
