Description

Access method and site and access point

Technical field

The present invention relates to the field of communications technologies, and in particular, to an access method, a station, and an access point.

Background technique

In a traditional 802.11 system, when a station (Station, STA) communicates with an access point (AP), in many communication links, the STA needs to continuously monitor, resulting in excessive power consumption. For example, in a conventional 802.11 system, the STA needs to send a Probe Request Frame for active scanning to determine whether there is an available AP nearby. Generally, the STA traverses one or more channels. For each channel, the STA sends a probe request frame on the channel, and then waits for the AP to reply to the probe response frame on the channel, if at some time. If no probe response frame is received, the STA switches to the next channel to continue transmitting the probe request frame, and waits for the probe response frame to be received by the AP. During the whole process, if the STA receives one or more probe response frames, the AP may select the AP that is most suitable for access according to the one or more probe response frames to complete the scanning process. If there is no AP on a certain channel, the STA will not receive any reply after sending the probe request frame, but since the STA does not know in advance that there is no AP on the channel, it still needs to monitor the channel until timeout. The power consumption of the STA is too large.

At present, there is no perfect mechanism to reduce the power consumption between STA and AP communication, so a new mechanism is needed to reduce the power consumption of the site.

detailed description

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the corresponding drawings.

1 is an exemplary diagram of a Wireless Local Area Networks (WLAN) 100 in accordance with an embodiment of the present invention. As shown in FIG. 1, wireless local area network 100 includes an Access Point (AP) 102 and stations (Stations) 104-106, wherein stations 104-106 can communicate with access point 102 over a wireless link.

Currently, the standard adopted by WLAN is the Institute of Electrical and Electronics Engineers (IEEE) 802.11 series of standards. The WLAN may include a plurality of Basic Service Sets (BSSs), the nodes of the basic service set are site STAs, and the sites include access point class (Access Point, AP for short) and non-access point class sites ( None Access Point Station (Non-AP STA), each basic service set may include one AP and multiple Non-AP STAs associated with the AP. It should be noted that the above-mentioned STAs 104-106 are Non-AP STAs. The Non-AP STA is simply referred to as an STA, and the site of the access point class is referred to as an AP.

Access point class sites, also known as wireless access points or hotspots. The AP is an access point for mobile users to enter the wired network. It is mainly deployed in the home, inside the building, and inside the campus. The typical coverage radius is tens of meters to hundreds of meters. Of course, it can also be deployed outdoors. An AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect the STAs together and then connect the wireless network to the wired network. Specifically, the AP may be a terminal device with a Wireless Fidelity (WiFi) chip or a network device, such as a smart phone that provides an AP function or service. Optionally, the AP may be a device supporting the 802.11ax system. Further, the AP may be a device supporting multiple WLAN technologies such as 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

The STA may be a wireless communication chip, a wireless sensor, or a wireless communication terminal. For example: mobile phone supporting WiFi communication function, tablet computer supporting WiFi communication function, set-top box supporting WiFi communication function, smart TV supporting WiFi communication function, smart wearable device supporting WiFi communication function, and vehicle communication supporting WiFi communication function Devices and computers that support WiFi communication. Optionally, the site can support the 802.11ax system. Further optionally, the site supports multiple WLAN formats such as 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

It should be noted that, in the 802.11ax WLAN system after the Orthogonal Frequency Division Multiple Access (OFDMA) technology, the AP can perform uplink and downlink transmissions to different STAs on different time-frequency resources. The AP can adopt different modes for uplink and downlink transmission, such as OFDMA single-user multiple-input multiple-output (SU-MIMO) mode, or OFDMA multi-user multiple input multiple output (Multi-User Multiple). -Input Multiple-Output, referred to as MU-MIMO mode.

In general, the STA and the AP need to support the Wake UP Radio (WUR) function to achieve the purpose of reducing power consumption. However, in the prior art, the STA cannot know which APs support the WUR function. The embodiment of the invention provides an access method, and the station can know whether the access point has the WUR capability, which will be described in detail below with reference to FIG. 2 and FIG. 3.

2 is an exemplary flow diagram of an access method 200 in accordance with an embodiment of the present invention. In a particular implementation, method 200 can be performed by a site.

Step 202: The site generates a request frame, where the request frame is used to indicate an access point reply response frame with a wake-up radio WUR capability.

Step 204: The station sends the request frame.

Specifically, the station sends a request frame to the access point, where the request frame is used to indicate an access point reply response frame with the WUR capability of the wake-up radio, and when the access point determines that it has the WUR capability, the response frame is returned to the station. .

According to the access method provided by the embodiment of the present invention, the station generates and sends a request frame, where the request frame is used to indicate an access point reply response frame having the WUR capability for waking up the radio, and then the station receiving access point receives the request frame and After confirming that the response frame is replied to with the WUR capability, the site can know whether the access point has the WUR capability, thereby solving the problem that the prior art site cannot know whether the access point has the WUR capability.

Further, after the site obtains the WUR capability of the access point, the WUR-capable access point and the WUR-capable access point can be classified and displayed on the site interface for the user to select.

In a possible design, the request frame generated by the above site is a newly defined request frame, which is used to indicate an access point reply response frame with a wake-up radio WUR capability. The request frame may include at least a first field and a second field, where the first field is used to carry the identifier of the site, and the second field is used to indicate that the WUR-capable access point returns a response frame to the site.

In a possible design, the request frame is a probe request frame, and the probe request frame may include a first field, where the first field is used to indicate that the WUR-capable access point returns a response frame to the site, where the response frame is Probe response frame. It should be noted that, in the above case, the first field may be a newly added field in the request frame, or may be a reserved field in the request frame.

Further, the first field is included in a physical layer preamble of the request frame. For example, when the request frame is a probe request frame, the first field is included in a physical layer preamble of the probe request frame. When the first field is included in the physical layer preamble of the request frame, the access point can detect the first field faster, thereby improving the recognition efficiency of the access point. It should be noted that the first field may be located at other positions of the request frame, and the location may be set according to specific requirements, which is not limited herein. For example, when the request frame is a probe request frame, as shown in FIG. 2A, media access control of a Media Access Control Protocol Data Unit (MPDU) of the probe request frame (Media Access Control) , MAC) header contains Frame Control field, Duration/ID field, Address 1 field, Address 2 field, Address 3 field, Sequence control (Sequence control) field, High Throughput control (HT-control) field, Frame body field, and Frame Check Sequence (FCS) field; wherein the HT-control field contains very High High Throughput (VHT), High Efficiency (HE) field, and Aggregate congtrol field; further, the aggregation control field includes a Control ID field and Control information. In the field, the Control Information field contains the Wake Up Radio (WUR) field. The first field may be located in the MAC header of the MPDU of the probe request frame, and may be located in the control information field, where the WUR field in FIG. 2A is the first field.

It should be noted that the request frame sent by the above site is used to indicate the WUR-capable access point reply response frame, that is, only the access point has the WUR capability to respond to the response frame, and if there is no WUR capability, no reply is given. The WUR capability of the access point means that the access point supports the WUR function. For example, the access point can identify the WUR-related field in the request frame. It should be noted that, in addition to the access point reply response frame indicating the capability of waking up the radio WUR, the request frame may also indicate that the access point has other capabilities to respond to the response frame, such as but not limited to the access point. Need to have the corresponding bandwidth capability, the corresponding number of antennas, support multi-user transmission capabilities.

FIG. 3 is an exemplary flow diagram of an access method 300 in accordance with an embodiment of the present invention. In a particular implementation, method 300 can be performed by an access point.

Step 302: The access point receives the request frame, where the request frame is used to indicate an access point reply response frame with a wake-up radio WUR capability.

Step 304: The access point sends a response frame when it determines that it has the capability to wake up the radio WUR.

Specifically, the access point receives a request frame from the station, and the request frame is used to indicate that the access point with the wake-up radio WUR capability returns a response frame to the station, and the access point determines that it has the capability to wake up the radio WUR. The site sends a response frame.

The specific technical content involved in the foregoing method 300 has been clearly described above with reference to the accompanying drawings, such as, but not limited to, the foregoing method 200 and FIG. 2, and thus will not be further described herein.

It can be seen that the access point receives the request frame, and the request frame is used to indicate an access point reply response frame with the WUR capability of the wake-up radio. When the access point receives the request frame and confirms that it has the WUR capability, the access point The site responds to the response frame, so that the site can know that the access point of the response response frame has the WUR capability, thereby solving the problem that the prior art site cannot know whether the access point has the WUR capability.

FIG. 4 and FIG. 5 are another access method according to an embodiment of the present invention. The station can learn whether the access point has the WUR capability. Different from the solution described in FIG. 2 and FIG. 3, in the solution described in FIG. 4 and FIG. 5, the request frame sent by the station is an existing frame, and the indication information carried by the access point is not required to carry the indication, so that The site is able to know if the access point has the ability to wake up the radio WUR. A detailed description will be given below with reference to FIGS. 4 and 5.

4 is an exemplary flow diagram of an access method 400 in accordance with an embodiment of the present invention. In a particular implementation, method 400 can be performed by a site.

Step 402: The station sends a request frame and receives a response frame from the access point.

Step 404: The station extracts an access point capability indication in the response frame, and according to whether the access point has the capability of waking up the radio WUR.

According to the access method provided by the embodiment of the present invention, the station sends the request frame and receives the response frame from the access point, and further extracts the access point capability indication in the response frame from the response frame, and confirms the access point according to the method. Whether it has the ability to wake up the radio WUR, so that the site can query whether the access point has the WUR capability, thereby solving the problem that the prior art site cannot query whether the access point has the WUR capability.

Further, after the site query access point has the WUR capability, the WUR-capable access point and the WUR-capable access point may be classified and displayed on the site interface for the user to select.

In one possible design, the response frame replied by the access point is a newly defined response frame, and the response frame carries an indication of the capability of the access point. The response frame may include at least a first field and a second field, where the first field is used to carry the identifier of the foregoing site, and the second field is used to carry the capability indication of the access point.

In a possible design, the request frame is a probe request frame, and the response frame is a probe response frame. The probe response frame includes a first field, where the first field is used to carry the capability indication of the access point. It should be noted that the first field may be a newly added field in the response frame, or may be a reserved field in the response frame.

Further, the first field is included in a physical layer preamble of the response frame. For example, when the response frame is a probe response frame, the first field is included in a physical layer preamble of the probe response frame. When the first field is included in the physical layer preamble of the response frame, the station can detect the first field faster, thereby improving the recognition efficiency of the site. It should be noted that the first field may be located at other positions of the response frame, and the location may be set according to specific needs, which is not limited herein. For example, when the response frame is a probe response frame, as shown in FIG. 4A, media access control of a Media Access Control Protocol Data Unit (MPDU) of the probe response frame (Media Access Control) , MAC) header contains Frame Control field, Duration/ID field, Address 1 field, Address 2 field, Address 3 field, Sequence control (Sequence control) field, High Throughput control (HT-control) field, Frame body field, and Frame Check Sequence (FCS) field; wherein the HT-control field contains very High High Throughput (VHT), High Efficiency (HE) field, and Aggregate congtrol field; further, the aggregation control field includes a Control ID field and Control information. In the field, the Control Information field contains the Wake Up Radio (WUR) field. The first field may be located in the MAC header of the MPDU of the probe response frame, and may be located in the control information field, where the WUR field in FIG. 4A is the first field.

It should be noted that the request frame sent by the above site may be an existing capability query frame, and the WUR-capable access point carries the access point capability indication in the response frame replied to the site, and the WUR-capable access point The response frame replied to the site does not carry the access point capability indication. In addition, the foregoing access point capability indication is used to indicate whether the access point has WUR capability, and is not used to indicate other capabilities of the access point. In this case, the response frame received by the station may be a response frame including an indication of carrying the access point capability and a response frame not carrying the indication of the access point capability. It should be noted that when the response frame does not carry the access point capability indication, it may be a response frame in the prior art, such as a probe response frame.

FIG. 5 is an exemplary flow diagram of an access method 500 in accordance with an embodiment of the present invention. In a particular implementation, method 500 can be performed by an access point.

Step 502: The access point receives the request frame from the site.

Step 504: The access point returns a response frame to the station, where the response frame carries an access point capability indication, where the access point capability indication is used to indicate whether the access point has the capability to wake up the radio WUR.

In a specific implementation process, the access point returns a response frame to the site after receiving the request frame sent by the site, where the response frame carries an indication of the capability of the access point, where the access point capability indication is used to indicate whether the access point has Wake up the radio WUR capability.

The specific technical content involved in the above method 500 has been clearly described above with reference to the accompanying drawings, such as, but not limited to, the above method 400 and FIG. 4, and thus will not be further described herein.

It can be seen that the access point receives the request frame from the station and returns a response frame to the station, where the response frame carries an access point capability indication, where the access point capability indication is used to indicate whether the access point has a wake-up radio WUR capability, the station receives the response frame and extracts the access point capability indication in the response frame from the response frame, and confirms whether the access point has the capability of waking up the radio WUR, so that the station can know whether the access point is With the WUR capability, the problem in the prior art that the access point cannot know whether the access point has the WUR capability can be solved.

In the traditional 802.11 system, after the request frame is sent, the station needs to wait for the reply of the access point on the corresponding channel. When there is no response delay of the access point or the access point on the channel, the station will increase the work of the station. Consumption. Embodiments of the present invention provide an access method, which helps reduce power consumption of a station. A detailed description will be given below with reference to FIGS. 6 and 7.

FIG. 6 is an exemplary flow diagram of an access method 600 in accordance with an embodiment of the present invention. In a particular implementation, method 600 can be performed by a site.

Step 602: The primary communication module of the station sends a request frame, where the request frame is used to indicate that the access point needs to send a wake-up frame before communicating with the primary communication module.

Step 604: The main communication module starts to wake up the radio WUR module, and the main communication module enters a sleep state.

Step 606: The WUR module receives a wake-up frame from an access point.

Step 608: The WUR module starts the main communication module, and the WUR module enters a sleep state.

Under normal circumstances, the communication between the site and the access point is completed by the primary communication module and the access point of the site. For example, the primary communication module of the site sends a probe request frame to the access point, and receives the access point. The probe response frame is sent to complete the communication process between the site and the access point. It should be noted that the main communication module of the above site may be a transceiver module of a site that does not have WUR capability in the prior art.

In one possible design, the request frame in the above method 600 is a newly defined request frame, which is used to indicate that the access point needs to send a wake-up frame before communicating with the main communication module. The request frame may include at least a first field and a second field, where the first field is used to carry the identifier of the foregoing station, and the second field is used to indicate that the access point needs to send the wake-up frame before communicating with the primary communication module. In a possible design, the request frame in the foregoing method 600 is a probe request frame, and the probe request frame carries a sleep notification field, where the sleep notification field is used to indicate that the access point is to the main communication module. A wake-up frame needs to be sent before replying to the probe response frame. In this case, the main communication module of the station sends a probe request frame to start the wake-up radio WUR module, and then the main communication module enters a sleep state, and the WUR module starts to listen for the wake-up frame from the access point. After receiving the probe request frame sent by the station, the access point parses the sleep notification field in the probe request frame, and when needed to communicate with the primary communication module of the station, generates a wake-up frame according to the probe request frame, and sends the wake-up frame to the wake-up frame. The WUR module of the site. After the WUR module receives the wake-up frame sent by the access point to itself, the WUR module starts the main communication module of the above site, and the WUR module enters a sleep state. In addition, after transmitting the wake-up frame, the access point sends a probe response frame to the foregoing station, and the primary communication module of the site receives the probe response frame.

In a possible design, the request frame in the method 600 is an authentication request frame, and the authentication request frame carries a dormancy notification field, where the dormant notification field is used to indicate that the access point is to the main communication module. A wake-up frame needs to be sent before replying to the authentication response frame. In this case, the main communication module of the station sends the authentication request frame to start the wake-up radio WUR module, and then the main communication module enters the sleep state, and the WUR module starts to listen for the wake-up frame from the access point. After receiving the authentication request frame sent by the station, the access point parses the sleep notification field in the authentication request frame, and when needed to communicate with the main communication module of the station, generates a wake-up frame according to the authentication request frame, and sends the wake-up frame to the The WUR module of the site. After the WUR module receives the wake-up frame sent by the access point to itself, the WUR module starts the main communication module of the above site, and the WUR module enters a sleep state. In addition, after the access point sends the wake-up frame, the access point sends an authentication response frame to the foregoing station, and the primary communication module of the site receives the authentication response frame.

In a possible design, the request frame in the method 600 is an association request frame, and the association request frame carries a dormancy notification field, where the dormant notification field is used to indicate that the access point is to the main communication module. A wake-up frame needs to be sent before replying to the associated response frame. In this case, the main communication module of the station sends the association request frame to start the wake-up radio WUR module, and then the main communication module enters the sleep state, and the WUR module starts to listen for the wake-up frame from the access point. After receiving the association request frame sent by the station, the access point parses the sleep notification field in the association request frame, and when needed to communicate with the main communication module of the station, generates a wake-up frame according to the association request frame, and sends the wake-up frame to the The WUR module of the site. After the WUR module receives the wake-up frame sent by the access point to itself, the WUR module starts the main communication module of the above site, and the WUR module enters a sleep state. In addition, after transmitting the wake-up frame, the access point sends an association response frame to the foregoing station, and the primary communication module of the site receives the association response frame.

Further, the sleep notification field is included in a physical layer preamble of the request frame. For example, when the request frame is a probe request frame, the sleep notification field is included in a physical layer preamble of the probe request frame. It should be noted that the above-mentioned dormant notification field may also be located at other positions of the request frame, and the location thereof may be set according to specific needs, which is not limited herein. For example, when the request frame is a probe request frame, as shown in FIG. 6A, media access control of a Media Access Control Protocol Data Unit (MPDU) of the probe request frame (Media Access Control) , MAC) header contains Frame Control field, Duration/ID field, Address 1 field, Address 2 field, Address 3 field, Sequence control (Sequence control) field, High Throughput control (HT-control) field, Frame body field, and Frame Check Sequence (FCS) field; wherein the HT-control field contains very High High Throughput (VHT), High Efficiency (HE) field, and Aggregate congtrol field; further, the aggregation control field includes a Control ID field and Control information. In the field, the Control Information field contains the Wake Up Radio (WUR) field. The first field may be located in the MAC header of the MPDU of the probe request frame, and may be located in the control information field, where the WUR field in FIG. 6A is the first field.

In a possible design, the station in the method 600 is indicated by a first station identifier in the request frame, and the wake-up frame carries a second station identifier for indicating the station, where the The second site identifier is generated based on the first site identifier, and the length of the second site identifier is shorter than the length of the first site identifier. In a specific implementation process, the first site identifier in the request frame may be a MAC address of the site, or may be another identifier that may be used to identify the site, and is not limited herein. When the first site identifier is the MAC address of the site, the second site identifier carried by the wake-up frame is generated based on the MAC address of the site. For example, after receiving the request frame, the access point extracts the first site identifier, that is, the MAC address of the site, from the request frame, and truncates the MAC address of the site, and takes at least one of the bits as a site. The second site identifier is carried and the second site identifier is carried in the generated wake-up frame. It should be noted that when the WUR module of the foregoing site can identify the MAC address of the access point, the second site identifier of the site may also be calculated by using the MAC address of the site and the MAC address of the access point. For example, the MAC address of the above site is XORed with the MAC address of the access point, and at least one bit is taken out from the operation result as the second site identifier of the site. The WUR module compares the received site identifier with the site-based MAC address and the MAC address of the AP, and compares the second site identifier of the obtained site. If the two sites have the same identifier, the WUR can determine the wake-up. The frame is sent to itself. The second station identifier length is shorter than the first station identifier, which can reduce the overhead of the access point sending the wake-up frame and facilitate the WUR module of the station to receive the wake-up frame.

In a possible design, in the process of associating a site with an access point, the site has two associated modes to choose from, namely, a power saving mode and a normal mode. In the power saving mode, the main communication module of the station sends a request frame, where the request frame is used to indicate that the access point needs to send a wake-up frame before communicating with the main communication module, and then the main communication module of the station enters a sleep state, and the station The WUR module is turned on to receive the wake-up frame from the access point. In this case, the site needs to access the WUR-capable access point; in the normal mode, the station's main communication module sends the request frame, the request. The frame is an existing request frame, and then the main communication module of the station waits for the access point to reply to the response frame. In this case, the site needs to access the access point without WUR capability. For example, when the station determines that the current mode is the power saving mode, the primary communication module of the station sends a request frame on a frequency band, where the request frame is used to indicate that the access point needs to send a wake-up frame before communicating with the primary communication module. After the station sends the request frame, the main communication module of the site enters a sleep state, and the WUR module of the site is turned on. When the WUR module of the site does not receive the wake-up frame from the access point within a preset time, for example, the WUR module is in 2 If the wake-up frame from the access point is not received within seconds, the WUR module can restart the main communication module and enter another frequency band to send the request frame.

It can be seen that in the power saving mode, the station first accesses by sending a request frame in one frequency band. If the response frame of the access point is not received, the station enters another frequency band and continues to send the request frame for access. After all bands have been searched, the station can enter normal mode if it has not been successfully accessed. When the station determines that the current mode is normal mode, the station sends an existing request frame so that the station can access the available access points. It should be noted that the conditions for the above site to switch from the power saving mode to the normal mode can be set according to specific needs.

It should be noted that, since the WUR module in the foregoing method 600 is a low power consumption module, the WUR module can be always in an open state in the foregoing method 600, that is, the main communication module of the station sends a request frame, and the request frame is used to indicate The access point needs to send a wake-up frame before communicating with the main communication module, the main communication module enters a sleep state, the WUR module receives a wake-up frame from the access point, and the WUR module starts the main communication module. In the above process, the WUR module can be always on, the WUR module can be turned on when the site is turned on, or it can be turned on when the main communication module of the site sends the request frame, or it can be guaranteed to receive from the access point. The wake-up frame is turned on at any time, and there is no limit here.

FIG. 7 is a schematic flowchart of an access method 700 according to an embodiment of the invention. In a particular implementation, method 700 can be performed by an access point.

Step 702: The access point receives a request frame, where the request frame is used to indicate that the access point needs to send a wake-up frame before communicating with the main communication module of the station.

Step 704: The access point generates a wake-up frame according to the request frame.

Step 706: The access point sends the wake-up frame.

It is to be noted that the access point generates a wake-up frame according to the request frame and sends the wake-up frame. Specifically, when it is required to communicate with the main communication module of the station, the access point generates a wake-up frame according to the request frame and sends the Wake up the frame. When the access point needs to communicate with the primary communication module of the site, the access point may determine that data needs to be sent to the site, for example, the access point needs to send a response frame to the site, and the access point according to the request sent by the site. The frame generates a wake-up frame and sends a wake-up frame to the station.

The specific technical content involved in the foregoing method 700 has been clearly described above with reference to the accompanying drawings, such as, but not limited to, the foregoing method 600 and FIG. 6, and therefore will not be further described herein.

After the access point receives the request frame, the request frame is used to indicate that the access point needs to send a wake-up frame before communicating with the main communication module, and when the access point needs to communicate with the main communication module of the station, The request frame generates a wake-up frame, and sends the wake-up frame to the WUR module of the station, and the WUR module starts the main communication module of the station after receiving the wake-up frame from the access point, so that the main communication module of the station and the access point perform Communication, it can be seen that the main communication module of the station enters a sleep state after transmitting the request frame, and will restart when communication is needed, which helps to reduce power consumption.

FIG. 8 and FIG. 9 are another access method according to an embodiment of the present invention. Different from the schemes described in FIG. 6 and FIG. 7, the request frame sent by the station main communication module is an existing request frame, and the station main communication module sends. After the frame is requested, it enters the sleep state, and the main communication module will restart when communication is needed, which helps to reduce power consumption. A detailed description will be given below with reference to Figs. 8 and 9.

FIG. 8 is an exemplary flow diagram of an access method 800 in accordance with an embodiment of the present invention. In a particular implementation, method 800 can be performed by a site.

Step 802: The main communication module of the station sends a request frame.

Step 804: The main communication module of the site starts the wake-up radio WUR module, and the main communication module enters a sleep state.

Step 806: The WUR module receives the wake-up frame from the access point.

Step 808: The WUR module starts the main communication module, and the WUR module enters a sleep state.

Step 810: The main communication module receives a response frame.

In the above method 800, the main communication module of the station sends a request frame, after the request frame is transmitted, the main communication module starts the WUR module, the main communication module enters a sleep state, and the WUR module starts to listen for the wake-up frame from the access point. When the WUR module receives the wake-up frame sent by the access point to itself, the WUR module starts the main communication module, the WUR module enters a sleep state, and the main communication module receives the response frame from the access point.

It can be seen that the main communication module of the station enters a sleep state after transmitting the request frame, and restarts when communication is required, which helps to reduce power consumption.

In this case, a request response mechanism is pre-determined between the station and the access point, that is, the primary communication module of the default site enters a sleep state after transmitting the request frame, and the access point responds to the primary communication module of the site. Before the frame, the WUR module of the station needs to be sent to the WUR module of the station, so that the WUR module of the station starts the main communication module of the station, so that the main communication module of the station can receive the response frame from the access point. This request response mechanism can be predetermined by criteria.

In a possible design, the station in the above method 800 is indicated by a first station identifier in the request frame, and the wake-up frame carries a second station identifier for indicating the station, where the The second site identifier is generated based on the first site identifier, and the length of the second site identifier is shorter than the length of the first site identifier. In a specific implementation process, the first site identifier in the request frame may be a MAC address of the site, or may be another identifier that may be used to identify the site, and is not limited herein. When the first site identifier is the MAC address of the site, the second site identifier carried by the wake-up frame is generated based on the MAC address of the site. For example, after receiving the request frame, the access point extracts the first site identifier, that is, the MAC address of the site, from the request frame, and truncates the MAC address of the site, and takes at least one of the bits as a site. The second site identifier is carried and the second site identifier is carried in the generated wake-up frame. It should be noted that when the WUR module of the foregoing site can identify the MAC address of the access point, the second site identifier of the site may also be calculated by using the MAC address of the site and the MAC address of the access point. For example, the MAC address of the above site is XORed with the MAC address of the access point, and at least one bit is taken out from the operation result as the second site identifier of the site. The WUR module compares the received site identifier with the site-based MAC address and the MAC address of the AP, and compares the second site identifier of the obtained site. If the two sites have the same identifier, the WUR can determine the wake-up. The frame is sent to itself. The second station identifier length is shorter than the first station identifier, which can reduce the overhead of the access point sending the wake-up frame and facilitate the WUR module of the station to receive the wake-up frame.

In a possible design, the request frame in the foregoing method 800 is a probe request frame, and the response frame received by the station is a probe response frame. In this case, the main communication module of the station sends a probe request frame to start the wake-up radio WUR module, and then the main communication module enters a sleep state, and the WUR module starts to listen for the wake-up frame from the access point. After receiving the probe request frame sent by the station, the access point generates a wake-up frame according to the probe request frame, and sends the wake-up frame to the WUR module of the site. After the WUR module receives the wake-up frame sent by the access point to itself, the WUR module starts the main communication module of the above site, and the WUR module enters a sleep state. In addition, after transmitting the wake-up frame, the access point sends a probe response frame to the foregoing station, and the primary communication module of the site receives the probe response frame.

In a possible design, the request frame in the foregoing method 800 is an authentication request frame, and the response frame received by the station is an authentication response frame. In this case, the main communication module of the station sends the authentication request frame to start the wake-up radio WUR module, and then the main communication module enters the sleep state, and the WUR module starts to listen for the wake-up frame from the access point. After receiving the authentication request frame sent by the station, the access point generates a wake-up frame according to the authentication request frame, and sends the wake-up frame to the WUR module of the site. After the WUR module receives the wake-up frame sent by the access point to itself, the WUR module starts the main communication module of the above site, and the WUR module enters a sleep state. In addition, after the access point sends the wake-up frame, the access point sends an authentication response frame to the foregoing station, and the primary communication module of the site receives the authentication response frame.

In a possible design, the request frame in the foregoing method 800 is an association request frame, and the response frame received by the station is an association response frame. In this case, the main communication module of the station sends the association request frame to start the wake-up radio WUR module, and then the main communication module enters the sleep state, and the WUR module starts to listen for the wake-up frame from the access point. After receiving the association request frame sent by the station, the access point generates a wake-up frame according to the association request frame, and sends the wake-up frame to the WUR module of the foregoing site.
