A transmitting device, comprising:

• a memory configured to store a computer program;
• and
• a processor configured to invoke and execute the computer program stored in the memory, to cause the transmitting device to:
• transmit an ultra-high reliability (UHR) physical layer (PHY) protocol data unit (PPDU), wherein the UHR PPDU contains at least one of:
• a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal field (L-SIG), a repeated legacy signal field (RL-SIG), a universal signal field (U-SIG), an ultra-high reliability signal field (UHR-SIG), an ultra-high reliability short training field (UHR-STF), an ultra-high reliability long training field (UHR-LTF), a data field, or a packet extension (PE) field.
