It should be understood that a device with a communication function in the network/system in the embodiment of the present application may be referred to as a communication device. Taking the communication system 100 shown in FIG. 1 as an example, the communication equipment may include an access point 110 and a station 120 with a communication function, and the access point 110 and the station 120 may be the specific equipment described above, which will not be repeated here. The communication device may also include other devices in the communication system 100, such as network controllers, gateways and other network entities, which are not limited in this embodiment of the present application.

The term "and/or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship.

For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also indicate that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also indicate that there is an association between A and B relation.

The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application. The terms "first", "second", "third" and "fourth" in the specification and claims of the present application and the drawings are used to distinguish different objects, rather than to describe a specific order . Furthermore, the terms "include" and "have", as well as any variations thereof, are intended to cover a non-exclusive inclusion.

In the embodiment of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, may include the WiFi protocol and related protocols applied to future Wi-Fi communication systems, which is not limited in the present application.

Since the Media Access Control (MAC) address of the device is globally unique and permanent, network attackers can easily track the user by tracking the MAC address of the device, resulting in the exposure of a large amount of private information of the user on the network. Therefore, in response to this problem, a randomized MAC address function is proposed to improve user privacy.

When STA interacts with AP using RMA, there are two problems:

1. There may be two types of STAs in a Basic Service Set (BSS): STAs that support random MAC addresses (Random MAC Address, RMA), and STAs that do not support random MAC addresses. As a result, frames transmitted internally by the BSS may include frames carrying real MAC addresses or frames carrying random MAC addresses. For the real MAC address and the random MAC address, the processing mechanism of the receiving end will be very different. For example, the random MAC address will require the receiving end to perform unique user identity authentication to prove that different MAC addresses correspond to the same STA.

2. For the STA with a random MAC address, if the receiving end needs to authenticate the STA every time, it will increase the processing complexity of the receiving end and increase the power consumption of the system.

Therefore, how to reduce the processing complexity of the receiving end in a scenario where two types of STAs with real MAC addresses and random MAC addresses coexist is an urgent problem to be solved.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific examples. As optional solutions, the above related technologies may be combined with the technical solutions of the embodiments of the present application in any combination, and all of them belong to the protection scope of the embodiments of the present application. The embodiment of the present application includes at least part of the following contents.

FIG. 2 is a schematic interaction diagram of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 2, the method 200 includes the following content:

S210. The station device sends a first frame to the access point device, where the first frame includes random media access control MAC address control information, and the random MAC address control information includes first indication information and/or second indication information, The first indication information is used to indicate whether the MAC address of the station device is a random MAC address, and the second indication information is used to indicate whether the random MAC address of the station device has changed.

In some embodiments of the present application, the station device may use a real MAC address or a random MAC address (ie RMA) to communicate with the access point device. The access point device can use the real MAC address to communicate with the station device.

It should be understood that, in this embodiment of the present application, the real MAC address may refer to a MAC address used to uniquely identify a site device, and the real MAC address is usually unchanged.

It should be noted that the first indication information is used to indicate whether the MAC address of the station device in the first frame is a random MAC address, in other words, whether the MAC address of the station device is randomized, and the first indication Information can also be called RMA indicator (RMA indicator). The second indication information is used to indicate whether the random MAC address of the station device has changed, which may refer to whether the random MAC address of the station device is relative to the last frame (that is, the last frame sent by the station device to the access point device). Whether the random MAC address used in one frame is changed, the second indication information may also be called an RMA changed indicator (RMA changed indicator).

It should be understood that the embodiment of the present application does not limit the change frequency and change manner of the random MAC address. For example, the random MAC address may change with time, or change periodically, or change triggered by an event.

In some embodiments, the first frame may include the MAC address of the station device, and also include random MAC address control information (RMA control for short), which is used to indicate information related to the randomization of the MAC address of the station device. That is, when the site device uses the MAC address to send a frame to the access point device, it can carry the randomization related information of the MAC address at the same time, so that the access point device can perform corresponding processing according to the randomization related information of the MAC address, reducing the access point. The processing complexity of the ingress device. For example, the access point device may perform identity authentication on the station device only when the random MAC address of the station device changes.

In some embodiments, when the MAC address included in the first frame is a real MAC address, the first frame may not include random MAC address control information, in other words, the first frame does not include random MAC address information. In the case of address control information, it can be considered that the first frame uses a real MAC address.

It should be understood that, in the embodiment of the present application, the first frame may be any frame sent by the station device to the access point device, such as a data frame (data frame), a management frame (management frame), a control frame (control frame) etc., or other frames introduced in the standard evolution. When the site device uses the MAC address to send the frame to the access point device, it can carry the RMA control information, which is not limited in this application.

In some embodiments, the reserved (reserved) bits in the first frame may be used to carry the random MAC address control information, for example, the reserved bits in the first frame may be redefined as RMA control fields for carrying the The first indication information and/or the second indication information.

It should be understood that the reserved bits in the embodiments of the present application may refer to undefined bits, or may also be defined but unused bits, that is to say, the meanings indicated by these bits have no practical significance. In this case, these bits can be used to carry random MAC address control information.

In some other embodiments, an element (element) or a field (field) may also be added in the first frame to carry the random MAC address control information. For example, an RMA control element is added in the first frame, and the RMA control element includes an RMA indicator (RMA indicator) field and an RMA changed indicator (RMA changed indicator) field for carrying the first indication information and the second indication information respectively . For another example, an RMA control field is added in the first frame, and the RMA control field includes an RMA indicator subfield (subfield) and an RMA changed indicator subfield, which are used to carry the first indication information and the second indication information respectively.

In yet other embodiments, the random MAC address control information may be carried by using a reserved value or an invalid value of a specific field in the first frame. Optionally, the specific field may refer to any field with a reserved value or an invalid value in the first frame, which is not limited in this application.

Hereinafter, taking the first frame as a data frame, management frame and control frame as an example, the indication method of random MAC address control information will be described in detail, but the application is not limited thereto. When the first frame is other frames, the design method is similar.

Embodiment 1: The first frame is a data frame or a management frame

The data frame or the management frame may include a HT control (control) field, and when the first frame is a data frame or a management frame, random MAC address control information may be carried by the HT Control field in the data frame or the management frame.

For example, random MAC address control information may be carried through a reserved field in the HT Control field.

In some embodiments, for different types of station equipment, the frame format of the HT Control field in the data frame or the management frame is different, so the indication mode of the random MAC address control information can be designed according to the type of the station equipment.

In some embodiments, the type of site equipment may include non-China Millimeter-wave Multi-gigabit (non-CMMG) STA and China Millimeter-wave Multi-gigabit (China Millimeter-wave Multi-gigabit) STA. - gigabit, CMMG) STA. Further, non-CMMG STA may include high throughput (High Throughput, HT) STA, very high throughput (Very High Throughput, VHT) STA, high efficiency (High Efficiency, HE) STA, extremely high throughput (Extreme High Throughput, EHT) STA.

As shown in Table 1, the HT Control field of Non-CMMG STA is divided into the following three categories according to the values of the B0 and B1 bits: HT Variant, VHT Variant, and HE Variant.

surface

In some embodiments, for HT STAs, random MAC address control information can be carried through the HT Control Middle field in the HT Control field. In some embodiments, the HT Control Middle field occupies bits B1 to B29 of the HT Control field.

Figure 3 is a schematic format diagram of the HT Control Middle field. As shown in Figure 3, the HT Control Middle field may include the following fields:

Link Adaptation Control, Calibration Position, Calibration Sequence, Reservation, Channel State Information (CSI)/Steering, HT Zero Data Physical Layer Protocol Data Unit (Null Data PPDU, NDP) notification (Announcement), reservation, drop qualified indicator (Drop Eligibility Indicator, DEI).

It can be seen from Figure 3 that in the HT Control Middle field, bits B19 to B20 and bits B24 to B27 are reserved fields, with a total of 6 bits. Therefore, some or all of these 6 bits can be used to carry random MAC address control information. For example, 2 bits may be selected among the 6 reserved bits to carry random MAC address control information.

Figure 4 is a schematic format diagram of the HT Control Middle field carrying RMA indicator and RMA changed indicator through B19 and B20. Among them, B19 is used to indicate whether the MAC address is randomized, that is, as an RMA indicator. As an example, a value of B19 of 0 indicates that the MAC address of the site device is a real MAC address, and a value of 1 indicates that the MAC address of the site device is a randomized MAC address. B20 is used to indicate whether the randomized MAC address has changed, that is, as an RMA changed indicator. As an example, a value of 0 for B20 indicates that the randomized MAC address has not changed, and a value of 1 indicates that the randomized MAC address has changed.

In some embodiments, for the HE STA, random MAC address control information can be carried through the A-Control field in the HT Control field. In some embodiments, the A-Control field occupies bits B2 through B31 of the HT Control field.

Figure 5 is an example diagram of the frame format of the A-Control field, as shown in Figure 5, the A-Control field includes a Control List (Control List) field and a padding (Padding) field. Wherein, the Control List field includes one or more Control subfields, and the Control subfield further includes a Control identification (Identify, ID) field and a control information (Control Information) field.

In some embodiments, the reserved value of the Control ID field can be used to indicate that the A-Control field carries random MAC address control information, and the corresponding Control Information field is further used to carry random MAC address control information.

For example, if the value of Control ID is 9, 11-14 is a reserved value, that is, it does not correspond to explicit control information. In this case, for example, the Control ID can be reserved to indicate that the A-Control field carries a random MAC address control information.

Figure 5 is an example of random MAC address control information indicated by the reserved value of Control ID 9, then the Control ID corresponds to the RMA control, and the Control Information field can be 2 bits, of which 1 bit is used to indicate the MAC address of the site device Whether the address is randomized, that is, as an RMA indicator. For example, a value of 0 indicates that the MAC address of the site device is a real MAC address, and a value of 1 indicates that the MAC address of the site device is a randomized MAC address. Another bit is used to indicate whether the randomized MAC address has changed, that is, as the RMA changed indicator. For example, a value of 0 indicates that the random MAC address of the site device has not changed, and a value of 1 indicates that the random MAC address of the site device has changed. Fig. 6 is an exemplary frame structure diagram of the RMA Control field.

In some embodiments, the EHT STA adds multi-link and multi-AP cooperation functions on the basis of the HE STA, and its corresponding HT Control field structure is the same as the HT Control field structure corresponding to the HE STA. Therefore, the random MAC address control of the EHT STA Refer to the relevant design of HE STA for the indication method of information, and will not repeat them here. That is to say, for EHT STA, random MAC address control information can also be carried through the A-Control field in the HT Control field.

In some embodiments, for the CMMG STA, random MAC address control information can be carried through the HT control field. For example, carried by the reserved field in the HT control field. The specific position carried in the HT control field can be designed according to the frame structure of the HT control field corresponding to the CMMG STA.

Figure 7 is a schematic diagram of the structure of the HT control field corresponding to the CMMG STA. As shown in Figure 7, the HT Control field may include the following fields:

Modulation and Coding Scheme Request ((Modulation and Coding Scheme, MCS) Request, MRQ), MCS Feedback (MCS Feedback, MFB), MCS Feedback Sequence Identifier (MCS Feedback Sequence Identifier, MFSI), MRQ Sequence Number Identifier (MRQ Sequence Identifier, MSI)/Space-Time Block Coding (STBC), feedback (Feedback, FB) transmission type (Tx Type), unsolicited (Unsolicited) MFS, CSI/Steering, CMMG NDP Announcement, CMMG connection Incoming policy (Access Category, AC) restriction (Constraints), reverse expansion channel (Reverse Direction Grant, RDG)/more (more) PPDU, reservation.

In some embodiments, the HT Control field of the CMMG STA has a total of 32 bits, of which B29 to B31 are reserved fields with a total of 3 bits, so any two bits of the 3 bits can be used to carry random MAC address control information.

As shown in FIG. 8, it is an exemplary format diagram of the HT Control field carrying random MAC address control information through B29 and B30. Among them, B29 is used to indicate whether the MAC address is randomized, that is, as an RMA indicator. As an example, a value of B29 of 0 indicates that the MAC address of the site device is a real MAC address, and a value of 1 indicates that the MAC address of the site device is a randomized MAC address. B30 is used to indicate whether the randomized MAC address has changed, that is, as an RMA changed indicator. As an example, a value of 0 for B30 indicates that the random MAC address of the site device does not change, and a value of 1 indicates that the random MAC address of the site device changes.

The above describes how HT STA, HE STA, EHT STA and CMMG STA indicate the random MAC address. The following describes the setting method of the station device side for the random MAC address control information and the access point device for the random MAC address control information. Interpretation method.

It should be understood that, in this embodiment of the present application, the site device and the access point device have the same understanding of the specific location that carries the random MAC address control information, so that the site device can carry the random MAC address control information in a consistent manner. Correspondingly, the access point device may acquire the randomized MAC address control information at the corresponding position and further analyze it to determine MAC address randomization-related information of the station device.

With reference to FIG. 9 , an implementation manner of setting random MAC address control information by the site equipment is described, which is recorded as setting manner 1.

It should be understood that the first setting method can be applied to HT STA, HE STA, EHT STA and CMMG STA. For different STAs, it is only necessary to set the RMA control field in different fields.

S303. The site device sets the RMA indication in the RMA control information to 0, indicating that the site device uses a real MAC address.

For the HT STA, for example, a reserved bit (eg B19) in the HT control middle in the HT control field can be set to 0.

For CMMG STA, for example, the reserved bit (eg B29) in the HT control field can be set to 0.

For HE STA and EHT STA, for example, the Control ID field in the A-Control field can be set to a reserved value (for example, 9), and the RMA indicator in the Control Information field can be further set to 0.

S304. The site device sets the RMA indication in the RMA control information to 1, indicating that the site device uses a random MAC address.

For an HT STA, for example, a reserved bit (eg B19) in the HT control middle in the HT control field may be set to 1.

For CMMG STA, for example, a reserved bit (eg B29) in the HT control field can be set to 1.

For HE STA and EHT STA, for example, the Control ID field in the A-Control field can be set to a reserved value (for example, 9), and the RMA indicator in the Control Information field can be further set to 1.

Further, S305, the station device determines whether the current random MAC address has changed relative to the random MAC address used when the station device sent the last frame to the access point device.

If not changed, execute S306; otherwise, execute S307.

S306. The site device sets the RMA change indication in the RMA control information to 0, indicating that the random MAC address of the site device has not changed.

For an HT STA, for example, a reserved bit (for example, B20) in the HT control middle in the HT control field may be set to 0.

For CMMG STA, for example, the reserved bit (for example, B30) in the HT control field can be set to 0.

For HE STA and EHT STA, for example, the Control ID field in the A-Control field can be set to a reserved value (for example, 9), and the RMA Changed indicator in the Control Information field can be further set to 0.

S307. The site device sets the RMA change indication in the RMA control information to 1, indicating that the random MAC address of the site device changes.

For the HT STA, for example, a reserved bit (for example, B20) in the HT control middle in the HT control field can be set to 1.

For the CMMG STA, for example, the reserved bit (for example, B30) in the HT control field can be set to 1.

One frame carries the plurality of control information.

If the control information to be sent includes random MAC address control information and second control information, the second control information may be other control information shown in FIG. 5 except the RMA control. Can include the following situations:

Case 1: The second control information and the randomized MAC address control information do not exceed the maximum number of bits that can be carried in the A-control field, therefore, all control information can be carried in the A-control field.

In this case, the A-control field includes a first control ID field and a first control information field, and the value of the first control ID field is a first value, indicating that the first frame carries the random MAC Address control information, the first indication information and the second indication information are carried in the first control information field, wherein the first value is a reserved value of a control ID.

As shown in Figure 14, the frame format of the A-control field of the RMA control example is indicated by the reserved value 9.

In S524, the AP may extract multiple pieces of control information from the A-control field, and further, the access point device may perform subsequent operations according to the multiple pieces of control information.

Case 2: The second control information and the randomized MAC address control information exceed the maximum number of bits that can be carried by the A-control field. In this case, all the control information needs to be sent through multiple frames.

For example, the random MAC address control information is sent through the first frame, and the second control information is sent through the second frame.

Wherein, the A-control field in the first frame includes a first control ID field and a first control information field, and the value of the first control ID field is a first value, indicating that the first frame carries the Random MAC address control information, the first indication information and the second indication information are carried in the first control information field, wherein the first value is a reserved value of a control ID.

Wherein, the control information to be sent by the station device includes random MAC address control information and second control information, and the number of bits occupied by the random MAC address control information and the second control information is greater than the maximum number of bits that can be carried by the A-control field, so , the two pieces of control information need to be sent in two frames, for example, the random MAC address control information is sent in the first data frame or the first management frame, and the second control information is sent in the second data frame or the second management frame.

As shown in Figure 17, the following steps may be included:

S531. The station device determines that the current random MAC address of the station device has changed relative to the random MAC address in the last frame (that is, the last frame sent by the station device to the access point device), and the station device waits to send a message to the access point. The device sends data frames or management frames.

Further, subsequent operations may be performed according to the extracted control information.

In some embodiments of the present application, the random MAC address control information may not include the first indication information, but include the second indication information. In this case, as an implementation manner, whether the MAC address of the station device is randomized may be indicated by a specific value of a specific field.

In some embodiments, the site device may not carry random MAC address control information when using a real MAC address, and only carry an RMA change indication when using a random MAC address.

For HE STAs and EHT STAs, the site device may set the value of the control ID field included in the A-control field to not be The first value (such as 9) indicates that the A-control field does not carry random MAC address control information, and the Control Information field in the A-control field does not include the random MAC address control information; in the first frame In the case where the MAC address of the site device is a random MAC address, the A-control field is set to include a third control ID field and a third control information field, and the value of the third control ID field is the first value , indicating that the MAC address of the site device in the first frame is a random MAC address, the random MAC address control information includes an RMA change indication, and the RMA change indication is carried in the third control information field, wherein the The first value is a reserved value of the control ID. Figure 18 shows the frame format of the A-control field carrying the RMA control indicated by the reserved value 9.

In conjunction with FIG. 19 , another implementation manner of setting random MAC address control information by the site device is described, which is denoted as setting manner 2.

It should be understood that the second setting method can be applied to HE STA and EHT STA, and a similar design can also be made for HT STA and CMMG STA, and the present application is not limited thereto.

As shown in Figure 19, the following steps may be included:

S601. The station device determines to send a data frame or a management frame to the access point device;

S603, the site device does not carry RMA control information in the A-Control field, indicating that the site device uses a real MAC address.

For example, if you need to carry the second control information, you can set the value of the Control ID field in the Control list in the A-Control field to the Control ID corresponding to the second control information, and the Control list does not include the value of the first A Control ID field of one value, wherein, when the value of the Control ID field is the first value, it means that the A-Control field carries RMA control information.

S604, the site device carries RMA control information in the A-Control field, indicating that the site device uses a random MAC address.

For example, the Control ID field in the A-Control field may be set to the first value (eg, 9).

Further, S605, the station device determines whether the current random MAC address has changed relative to the random MAC address used when the station device sent the last frame to the access point device.

If not changed, execute S606, otherwise execute S607.

S606. The station device sets the RMA change indication to 0, indicating that the random MAC address of the station device has not changed.

For example, the RMA Changed indicator in the Control Information field in the Control list in the A-Control field can be set to 0.

S607. The site device sets the RMA change indication to 1, indicating that the random MAC address of the site device changes.

For example, the RMA Changed indicator in the Control Information field in the Control list in the A-Control field can be set to 1.

In conjunction with FIG. 20 , an interpretation method of the access point device for the random MAC address control information in the data frame or management frame sent by the station device is described, which is denoted as the second interpretation method.

As shown in Figure 20, the following steps may be included:

S701. The access point device receives a data frame or a management frame sent by the station device;

S702, the access point device determines whether the MAC address of the site device is a random MAC address according to whether the data frame or the management frame carries RMA control information;

If the RMA control information is not carried, it means that the site device uses a real MAC address, and S703 is executed.

If the RMA control information is carried, it means that the site equipment uses a random MAC address, and then S704 is executed.

For HE STA and EHT STA, the access point device can determine whether the data frame or the management frame carries the RMA control according to whether the Control ID field in the A-Control field is the first value (for example, 9).

For example, if the A-Control field does not include the Control ID field with the first value, it is determined that the data frame or the management frame does not carry the RMA control, otherwise, it is determined that the data frame or the management frame carries the RMA control.

S703. In the case that the site device uses a real MAC address, the access point device can determine whether it has been authenticated or whether an association has been established according to the real MAC address. Further, the site device has been authenticated, and the site device and the access point When the point device has been associated, the access point device can directly communicate with the station device.

S704, the access point device determines whether the random MAC address of the station device changes according to whether the RMA change indication in the data frame or the management frame is 1.

If there is a change, execute S705, otherwise execute S706.

S705. In the case that the random MAC address of the site device has not changed, the access point device can determine whether it has been authenticated or whether an association has been established according to the random MAC address. Further, the site device has been authenticated, and the site device and When the AP device has been associated, the AP device can directly communicate with the station device.

S706. When the random MAC address of the station device changes, the access point device may verify the identity information of the station device, and communicate with the station device if the verification is passed.

In some embodiments, the control information to be sent by the station device includes a plurality of control information, and the plurality of control information includes random MAC address control information and other control information, such as second control information. For the second setting method, the station device It may also be determined according to the size of the multiple pieces of control information whether to send in one frame or to send in multiple frames. Can include the following situations:

Case 1: The second control information and the randomized MAC address control information do not exceed the maximum number of bits that can be carried in the A-control field. In this case, all the control information can be carried in the A-control field.

Wherein, for the setting manner of the first control ID field and the first control information field, refer to the description shown in FIG. 19 .

For this case 1, HE STA, EHT STA and AP can use the sequence diagram shown in Figure 13 to interact. The difference for case 1 is that multiple control information can be extracted from the A-control field in S524, and only the RMA changed indicator is included in the RMA control information, and further, the access point device can perform subsequent operations.

Wherein, the A-control field in the first frame includes a first control ID field and a first control information field, and the value of the first control ID field is a first value, indicating that the first frame carries The random MAC address control information, the RMA changed indicator is carried in the first control information field. Wherein, for the setting manner of the first control ID field and the first control information field, refer to the description shown in FIG. 19 .

In this case 2, the first frame may be sent before the second frame, that is, the first frame carrying the random MAC address control information is sent first, and then the second frame carrying the second control information is sent, which is beneficial This prevents the loss of the first frame from causing the access point device to misjudge the MAC address of the site device as the real MAC address.

In some embodiments, in case 2, the first frame is a data frame or a management frame that only includes RMA control information.

For this case 2, the station device and the access point device may adopt the interaction sequence diagram shown in FIG. 17 , and refer to the relevant description in FIG. 17 for the specific process, which will not be repeated here.

To sum up, for an HT STA, the reserved field in the HT control middle field in the data frame or the HT control field in the management frame can be used to carry RMA control information. In this case, the format of the HT control middle field can be, for example, As shown in Figure 4.

Further, the HT STA can set the value of the RMA control information according to the flow chart shown in Figure 9, so as to indicate the RMA control information to the AP. Correspondingly, the AP can interpret the RMA control information in the received data frame or management frame of the HT STA according to the flow chart shown in FIG. Information to perform subsequent operations. In some embodiments, the AP and the HT STA may process frames using MAC addresses according to the interaction sequence diagram in FIG. 11 .

Perform subsequent operations. In some embodiments, the AP and the CMMG STA may process frames using MAC addresses according to the interaction sequence diagram in FIG. 12 .

For HE STA and EHT STA, in some implementations, the Control List field in the A-Control field in the HT control field in the data frame or management frame can be used to carry the RMA control information, for example, by setting the value of the Control ID Set as a reserved value to indicate that the A-Control field carries RMA control information, and further carries the RMA indicator and RMA Changed indicator through the Control Information field. In this case, the format of the RMA control field is shown in Figure 6.

Further, the HE STA and the EHT STA may set the value of the RMA control information according to the flowchart shown in FIG. 9, so as to indicate the RMA control information to the AP. Correspondingly, the AP can interpret the RMA control information in the received data frame or management frame of the HE STA and EHT STA according to the flowchart shown in Figure 10 to obtain the RMA randomization related information of the HE STA and EHT STA, so Subsequent operations are performed according to the randomization related information.

In some embodiments, when there are multiple control information to be sent, the HE STA or EHT STA can send the multiple control information in the same data frame or management frame. In this case, the AP, the HE STA and the EHT STA Frames using MAC addresses can be processed according to the interaction sequence diagram in FIG. 13 .

In other embodiments, when there is multiple control information to be sent, the HE STA or EHT STA can carry the multiple control information in different data frames or management frames and send them. In this case, the AP and the HE STA and the EHT The STA can process the frame using the MAC address according to the interaction sequence diagram in FIG. 17 .

For HE STA and EHT STA, in some other implementations, the data frame or management frame can be indicated by whether the Control List field in the A-Control field in the HT control field in the data frame or management frame carries RMA control information Whether the MAC address in is randomized. For example, by setting the value of the Control ID as a reserved value to indicate that the A-Control field carries RMA control information, and further carries the RMA Changed indicator through the Control Information field, in this case, the format of the RMA control field is shown in Figure 18. .

Further, the HE STA and the EHT STA can set the value of the RMA control information according to the flow chart shown in Figure 19, so as to indicate the RMA control information to the AP. Correspondingly, the AP can interpret the RMA control information in the received data frame or management frame of the HE STA and EHT STA according to the flowchart shown in Figure 20 to obtain the RMA randomization related information of the HE STA and EHT STA, so Subsequent operations are performed according to the randomization related information.

Embodiment 2: the first frame is a control (control) frame.

In some embodiments, the control frame may be a non-sub 1GHz (non-Sub 1GHz, non-S1G) physical layer protocol data unit (Physical layer (PHY) Protocol Data Unit, PPDU) control frame.

In some embodiments, the first frame includes a Frame Control field, and the random MAC address control information is carried in the Frame Control field.

Protocol Version, Type, Subtype, To Distributed System, To DS, From DS, More Frag, Retry ), power management (Power Management), more data (more data), protected frame (Protected Frame), + high throughput control (High Throughput Control, HTC).

In related technologies, the six bits of To DS, From DS, More Frag, Retry, Protected Frame, and +HTC are reserved fields. Although these fields are defined, they do not carry information, but are set to 0. Therefore, such fields can be utilized to carry RMA control information.

For example, as shown in Figure 22, the Protected Frame can be redefined as an RMA Indicator. For example, if the value of the RMA Indicator is 0, it is used to indicate that the site device is using a real MAC address, and the value of the RMA Indicator is 1, indicating that the site device is using the MAC address. is a random MAC address. Redefine +HTC as RMA Changed indicator. For example, when the value of RMA Changed indicator is 1, it indicates that the randomized MAC address has changed, and when the value of RMA Changed indicator is 0, it indicates that the randomized MAC address has not changed.

It should be understood that when the value of the RMA Indicator is 1, the value of the RMA Changed indicator is meaningful.

In some embodiments, when the site device uses a random MAC address for the first time after joining the network, the RMA Changed indicator defaults to 0.

With reference to FIG. 23 , the setting manner of the random MAC address control information in the control frame is described.

Embodiment 2-3:

In order to reduce the processing complexity of the access point device, adjacent bits in the reserved bits may be multiplexed to indicate the type of the randomized control frame. For example, the four adjacent bits of To DS, From DS, More Frag, and Retry (that is, B11 B10 B9 B8) are used to indicate the type of the randomized control frame.

Table 6

Take the STA sending the Beamforming Report Poll frame to the AP as an example, the site device can set Typee Subtpye to 01 0100 when the MAC address is a real MAC address, and set Typee Subtpye to 0100 when the MAC address is a random MAC address 01 0010, and set the randomized control frame type field (ie B11 B10 B9 B8) to 0000, indicating that the control frame is Random Beamforming Report Poll.

Correspondingly, after receiving the control frame sent by the station device, the access point device can first determine whether the Type Subtpye is 01 0010, determine whether the MAC address of the station device is a randomized MAC address, and further, determine whether the MAC address of the station device When the address is a randomized MAC address, further determine the randomized control frame type according to the value of the randomized control frame type field (i.e. B11 B10 B9 B8), for example, if the value is 0000, then determine that the control frame is Random Beamforming Report Poll.
