1. A method of signaling a packet padding capability in a wireless area network in accordance with an Extremely High Throughput (EHT) communication protocol, comprising:
constructing a MAC control management frame by a first station (STA) device, the MAC control management frame comprising an EHT capability element comprising one or more fields indicating whether a packet extension value longer than 16 μs is supported by the first STA device, where the one or more fields comprise:
a common nominal packet padding field having a plurality of values to signal different packet extension values for use with all transmission constellations, spatial streams Nss, and resource unit (RU) allocations supported by the first STA device, including at least one packet extension value longer than 16 μs; and/or
a PHY packet extension threshold (PPET) field comprising a plurality of PPET values to signal packet extension values including at least one packet extension value longer than 16 μs; and
sending the MAC control management frame from the first STA device to a second STA device which performs data communication with the first STA device by using the packet extension value longer than 16 μs when supported by the first STA device; where a first value of the common nominal packet padding field indicates that the first STA device supports a first packet extension value of 0 μs for all transmission constellations, Nss, and RU allocations; where a second value of the common nominal packet padding field indicates that the first STA device supports a second packet extension value of 8 μs for all transmission constellations, Nss, and RU allocations; where a third value of the common nominal packet padding field indicates that the first STA device supports a third packet extension value of 16 μs for at least transmission constellations≤1024-QAM, Nss≤8 and RU≤996*2; and where a fourth value of the common nominal packet padding field indicates that the first STA device supports a fourth packet extension value longer than 16 μs for at least transmission constellations>1024-QAM or Nss>8 or RU>996*2.
