Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A communication apparatus, comprising:
a receiver configured to receive an extremely high-throughput physical layer protocol data unit (EHT PPDU), wherein the EHT PPDU comprises a legacy physical layer preamble and a new physical layer preamble, wherein the legacy physical layer preamble comprises a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal (L-SIG) field in turn, and wherein a first field of the new physical layer preamble is a repeat of a field in the legacy physical layer preamble and is modulated by binary phase shift keying (BPSK); and
a processor coupled to the receiver and configured to decode the EHT PPDU.
