Abstract

Provided is a communication method. The method includes: receiving, by a first station (STA), a control frame carrying first information and/or second information, wherein the first information is configured to identify the second information, and the second information comprises protected information.

First claim

1 . A communication method, comprising:
receiving, by a first station (STA), a control frame carrying first information and/or second information, wherein the first information is configured to identify the second information, and the second information comprises protected information.

2 . The method according to claim 1 , further comprising:
transmitting, by the first STA, protection capability information of the first STA for the control frame.

3 . The method according to claim 1 , further comprising:
acquiring a second verification information by digesting, by the first STA and based on a digest algorithm, all or part of fields of original information, wherein the digest algorithm comprises at least one of hash-based message authentication code, cipher block chaining MAC (CBC-MAC), Galois message authentication code (GMAC), counter with CBC-MAC (CCM), Galois/counter mode (GCM); and confirming, by the first STA, the identification as successful, in a case that the second verification information is consistent with the second information.

4 . The method according to claim 1 , wherein the first information comprises at least one of the following fields:
a specified AID; a protection method; a length of a processed result corresponding to each piece of original information; and a number of the original information.

5 . The method according to claim 1 , wherein the second information comprises a protected content field and at least one of a specified AID or a disambiguation bit, and the specified AID in the second information is different from the specified AID in the first information.

6 . The method according to claim 1 , wherein the control frame is a trigger frame, and the second information in the trigger frame comprises protected user information (User Info); or
wherein the control frame is an NDPA frame, and the second information in the NDPA frame comprises protected station information (STA Info).

7 . The method according to claim 6 , wherein in the case that the control frame is the trigger frame and the second information in the trigger frame comprises protected User Info:
the protected User Info in the trigger frame comprises one protected User Info field, and the protected User Info field is acquired by processing M original User Info fields, M being a positive integer; or the protected User Info in the trigger frame comprises a plurality of protected User Info fields, and each of the protected User Info fields is acquired by processing one original User Info field; or the protected User Info in the trigger frame comprises a partially protected User Info field and an unprotected User Info field, wherein the partially protected User Info field is acquired by processing part of fields in M original User Info fields; and wherein in the case that the control frame is the NDPA frame and the second information in the NPDA frame comprises protected STA Info:
the protected STA Info in the NDPA frame comprises one protected STA Info field, wherein the protected STA Info field is acquired by processing M original STA Info fields, M being a positive integer; or
the protected STA Info in the NDPA frame comprises a plurality of protected STA Info fields, and each of the protected STA Info fields is acquired by processing one original STA Info field; or
the protected STA Info in the NDPA frame comprises a partially protected STA Info field and an unprotected STA Info field, wherein the partially protected STA Info field is acquired by processing part of fields in M original STA Info fields.

8 . A first station (STA), comprising:
a processor and a memory, wherein the memory is configured to store a computer program, which when executed by the processor, causes the first STA to: receive a control frame carrying first information and/or second information, wherein the first information is configured to identify the second information, and the second information comprises protected information.

9 . The first STA according to claim 8 , wherein the computer program, which when executed by the processor, further causes the first STA to:
transmit protection capability information of the first STA for the control frame.

10 . The first STA according to claim 8 , wherein the computer program, which when executed by the processor, further causes the first STA to:
acquire a second verification information by digesting and based on a digest algorithm, all or part of fields of original information, wherein the digest algorithm comprises at least one of hash-based message authentication code, cipher block chaining MAC (CBC-MAC), Galois message authentication code (GMAC), counter with CBC-MAC (CCM), Galois/counter mode (GCM); and confirm the identification as successful, in a case that the second verification information is consistent with the second information.

11 . The first STA according to claim 8 , wherein the first information comprises at least one of the following fields:
a specified AID; a protection method; a length of a processed result corresponding to each piece of original information; and a number of the original information.

12 . The first STA according to claim 8 , wherein the second information comprises a protected content field and at least one of a specified AID or a disambiguation bit, and the specified AID in the second information is different from a specified AID in the first information.

13 . The first STA according to claim 8 , wherein the control frame is a trigger frame, and the second information in the trigger frame comprises protected user information (User Info); or
wherein the control frame is an NDPA frame, wherein the second information in the NDPA frame comprises protected station information (STA Info).

14 . The first STA according to claim 13 , wherein in the case that the control frame is the trigger frame and the second information in the trigger frame comprises protected User Info:
the protected User Info in the trigger frame comprises one protected User Info field, and the protected User Info field is acquired by processing M original User Info fields, M being a positive integer; or the protected User Info in the trigger frame comprises a plurality of protected User Info fields, and each of the protected User Info fields is acquired by processing one original User Info field; or the protected User Info in the trigger frame comprises a partially protected User Info field and an unprotected User Info field, wherein the partially protected User Info field is acquired by processing part of fields in M original User Info fields; and
wherein in the case that the control frame is the NDPA frame and the second information in the NPDA frame comprises protected STA Info:
the protected STA Info in the NDPA frame comprises one protected STA Info field, wherein the protected STA Info field is acquired by processing M original STA Info fields, M being a positive integer; or
the protected STA Info in the NDPA frame comprises a plurality of protected STA Info fields, and each of the protected STA Info fields is acquired by processing one original STA Info field; or
the protected STA Info in the NDPA frame comprises a partially protected STA Info field and an unprotected STA Info field, wherein the partially protected STA Info field is acquired by processing part of fields in M original STA Info fields.

15 . A second station (STA), comprising:
a processor and a memory, wherein the memory is configured to store a computer program, which when executed by the processor, causes the second STA to: transmit a control frame carrying first informat
