Abstract

A communication method includes: generating an extremely high-throughput physical layer protocol data unit (EHT PPDU) that 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 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 sending the PPDU.

Claims (28)

1. A communication method, comprising:

generating 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

sending the EHT PPDU.

2. The communication method of claim 1 , wherein the field in the legacy physical layer preamble is the L-SIG field and a value of a length field in the L-SIG field is exactly divided by 3.

3. The communication method of claim 1 , wherein the field in the legacy physical layer preamble is the L-SIG field, and wherein a value of a length field of the L-SIG field and the first field of the new physical layer preamble are both exactly divided by 3.

4. The communication method of claim 1 , wherein the EHT PPDU satisfying: the field in the legacy physical layer preamble is the L-SIG field and a value of a length field in the L-SIG field is exactly divided by 3.

5. The communication method of claim 1 , wherein the first field of the new physical layer preamble is right after the L-SIG field, and wherein the new preamble further comprises an EHT-SIG 2 field that is right after the EHT-SIG 1 field and carries resource unit (RU) allocation and user information.

6. A communication method, comprising:

receiving 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

decoding the EHT PPDU.

7. The communication method of claim 6 , wherein the field in the legacy physical layer preamble is the L-SIG field and a value of a length field in the L-SIG field is exactly divided by 3.

8. The communication method of claim 6 , wherein the field in the legacy physical layer preamble is the L-SIG field, and wherein a value of a length field of the L-SIG field and the first field of the new physical layer preamble are both exactly divided by 3.

9. The communication method of claim 6 , wherein the EHT PPDU satisfying: the field in the legacy physical layer preamble is the L-SIG field and a value of a length field in the L-SIG field is exactly divided by 3.

10. The communication method of claim 6 , wherein the first field of the new physical layer preamble is right after the L-SIG field, and wherein the new preamble further comprises an EHT-SIG 2 field that is right after the EHT-SIG 1 field and carries resource unit (RU) allocation and user information.
