Resource unit (RU) allocation within wireless communications

摘要

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 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 generates an orthogonal frequency division multiple access (OFDMA) frame that includes a preamble that specifies allocation and/or non-allocation of at least one resource unit (RU) for a communication channel and transmits the OFDMA frame to at least one other wireless communication device to be processed by the at least one other wireless communication device to determine the allocation of the at least one RU for the communication channel or the non-allocation of the at least one RU for the communication channel.

1. A wireless communication device comprising:
a communication interface; and processing circuitry that is coupled to the communication interface, wherein at least one of the communication interface or the processing circuitry configured to:
generate an orthogonal frequency division multiple access (OFDMA) frame that includes a preamble that specifies allocation of at least one resource unit (RU) for a communication channel or non-allocation of the at least one RU for the communication channel, wherein:
when the preamble specifies the allocation of the at least one RU for the communication channel, a multi-bit index of the preamble specifies at least one of a size or a location of the at least one RU allocated for the communication channel; andwhen the preamble specifies the non-allocation of the at least one RU for the communication channel, the multi-bit index of the preamble specifies the at least one of the size or the location of the at least one RU that is not allocated for the communication channel; andtransmit, via the communication channel, the OFDMA frame to at least one other wireless communication device to be processed by the at least one other wireless communication device to determine the allocation of the at least one RU for the communication channel or the non-allocation of the at least one RU for the communication channel.
