Abstract

A wireless communication method is provided. The method includes: transmitting, by a first device, a first frame to a second device. A communication device is provided. The communications device is a first device, and the communications device comprises a memory and a processor, where the memory is configured to store a computer program and the processor is configured to execute the computer program stored in the memory to cause the communication device to perform an operation of: transmitting a first frame to a second device.

First claim

What is claimed is:

1 . A wireless communication method, comprising:
transmitting, by a first device, a first frame to a second device.

2 . The method according to claim 1 , wherein the first frame is a null data physical layer protocol data unit announcement NDPA frame of a first type; the NDPA frame comprises a fourth field; and the fourth field is used to indicate whether the NDPA frame is of the first type.

3 . The method according to claim 2 , wherein the NDPA frame further comprises a sounding dialog token field; and the fourth field immediately follows the sounding dialog token field.

4 . The method according to claim 2 , wherein the fourth field comprises a first station information field; and the NDPA frame is determined as an NDPA frame of the first type in a case that the NDPA frame comprises the first station information field.

5 . The method according to claim 4 , wherein the NDPA frame being determined as the NDPA frame of the first type in the case that the NDPA frame comprises the first station information field comprises:
the NDPA frame being determined as the NDPA frame of the first type in a case that the NDPA frame comprises the first station information field and that an NDPA variant field of a sounding dialog token field in the NDPA frame is set to 3.

6 . The method according to claim 4 , wherein in a case that an AID 11 field of a station information field in the NDPA frame is a first value, the station information field is the first station information field.

7 . The method according to claim 6 , wherein the first value is greater than or equal to 2007 and less than or equal to 2047.

8 . The method according to claim 2 , wherein in a case that an NDPA variant field of a sounding dialog token field in the NDPA frame is set to 3 and a first station information field appears, the NDPA frame is an NDPA frame of the first type.

9 . A communications device, wherein the communications device is a first device, and the communications device comprises a memory and a processor, wherein the memory is configured to store a computer program and the processor is configured to execute the computer program stored in the memory to cause the communication device to perform an operation of:
transmitting a first frame to a second device.

10 . The communications device according to claim 9 , wherein the first frame is a null data physical layer protocol data unit announcement NDPA frame of a first type; the NDPA frame comprises a fourth field; and the fourth field is used to indicate whether the NDPA frame is of the first type.

11 . The communications device according to claim 10 , wherein the NDPA frame further comprises a sounding dialog token field; and the fourth field immediately follows the sounding dialog token field.

12 . The communications device according to claim 10 , wherein the fourth field comprises a first station information field; and the NDPA frame is determined as an NDPA frame of the first type in a case that the NDPA frame comprises the first station information field.

13 . A communications device, wherein the communications device is a second device, and the communications device comprises a memory and a processor, wherein the memory is configured to store a computer program, and the processor is configured to execute the computer program stored in the memory to cause the communications device to perform an operation of:
receiving a first frame transmitted by a first device.

14 . The communications device according to claim 13 , wherein the first frame is a null data physical layer protocol data unit announcement NDPA frame of a first type; the NDPA frame comprises a fourth field; and the fourth field is used to indicate whether the NDPA frame is of the first type.

15 . The communications device according to claim 14 , wherein the NDPA frame further comprises a sounding dialog token field; and the fourth field immediately follows the sounding dialog token field.

16 . The communications device according to claim 14 , wherein the fourth field comprises a first station information field; and the NDPA frame is determined as an NDPA frame of the first type in a case that the NDPA frame comprises the first station information field.

17 . The communications device according to claim 16 , wherein the NDPA frame being determined as the NDPA frame of the first type in the case that the NDPA frame comprises the first station information field comprises:
the NDPA frame being determined as the NDPA frame of the first type in a case that the NDPA frame comprises the first station information field and that an NDPA variant field of a sounding dialog token field in the NDPA frame is set to 3.

18 . The communications device according to claim 16 , wherein in a case that an AID 11 field of a station information field in the NDPA frame is a first value, the station information field is the first station information field.

19 . The communications device according to claim 18 , wherein the first value is greater than or equal to 2007 and less than or equal to 2047.

20 . The communication device according to claim 13 , in a case that an NDPA variant field of a sounding dialog token field in the NDPA frame is set to 3 and a first station information field appears, the NDPA frame is an NDPA frame of the first type.
