Description

Communication method, network equipment and terminal

Technical Field

The present invention relates to the field of wireless communications, and in particular, to a communication method, a network device, and a terminal.

Background

With the evolution of the WLAN (Wireless Local Area Network) standard, in a Wireless Fidelity (WiFi) Network, when there is no message transmission or reception (e.g. in the nondata phase), a terminal device (e.g. a workstation) may have a large part of energy wasted in the idle listening channel when there is no received signal. The IEEE (Institute of Electrical and Electronic Engineers) 802.11 working group is developing Low Power Wake Up Radio/Low Power Wake Up Receiver (LP-WUR, also called Wake Up Radio) as a core technology to reduce WiFi Power consumption. Therefore, in the communication process between a network device in a WiFi network, such as a wireless Access Point (AP), and a terminal, a communication method for reducing power consumption of the terminal device is needed.

In the prior art, a communication method for reducing the power consumption of terminal equipment is to use a low-power-consumption WUR for a terminal to replace an 802.11 host transceiver module to listen to a channel when a medium is idle. As shown in fig. 1, when the 802.11 host transceiver module of the terminal at the receiving end enters deep sleep, the WUR with low power consumption wakes up to start working. When an AP of a sending end needs to communicate with a terminal with a WUR and an 802.11 host transceiver module, the 802.11 host transceiver module of the AP sends a wakeup frame or a wakeup Packet (WURP) to the WUR of the terminal, the WURR receiving the WURP compares a WURR ID (WURR identification information) in the WURP with the WURR ID allocated by the WURR receiving module, if the comparison result is consistent, the WURR considers that the WURP is sent to the WURR, then the WURR wakes Up the 802.11 host transceiver module of the terminal, the WURR goes to sleep again, after the 802.11 host transceiver module of the terminal is awakened, the WURR sends a wakeup frame to the 802.11 host transceiver module of the AP to indicate that the 802.11 host transceiver module of the terminal is awakened successfully, and then the 802.11 host transceiver module of the AP communicates with the 802.11 host transceiver module of the awakened terminal. The 802.11 host transceiver module of the terminal enters the sleep mode after the communication with the 802.11 host transceiver module of the AP is completed, and the WUR of the terminal begins to listen to whether the WUP sent to the terminal exists or not so as to wake up the 802.11 host transceiver module of the terminal again.

However, the terminal sends the wakeup confirm frame to the 802.11 primary transceiver module of the AP using the 802.11 frame format, that is, the 802.11 primary transceiver module of the AP needs to be always turned on to wait for receiving the wakeup confirm frame, which causes a large power consumption, and especially when the wakeup process fails, the power consumption is increased because the wakeup confirm frame is not received for a long time.

Disclosure of Invention

The embodiment of the application provides a communication method, an access point and a terminal, and by responding to a received wake-up packet in a wake-up packet mode, power consumption in a communication process is effectively reduced, signaling overhead is reduced, and therefore communication time is effectively shortened.

In a first aspect, a communication method is provided, which may include: when a first device (a first terminal) has data to send to a second device (a network device, such as an AP), that is, the first device needs to perform uplink communication, the first device needs to generate a first wake-up packet. The first device sends a first wake-up packet to a wake-up receiver WUR of the second device to wake up a master transceiver module of the second device. The first wake-up packet may include WUR identification information of the second device, such as address information of the WUR, for instructing the second device to receive the first wake-up packet. The WUR of the first device receives a second wake-up packet for responding to the first wake-up packet, the second wake-up packet being sent by the second device.

The communication rule of the second device is initialized, that is, the second device is specified to respond to the received wake-up packet in a wake-up packet mode after receiving the wake-up packet, so that the main transceiver module of the first device communicates with the main transceiver module of the awakened second device. According to the communication method, after the second device receives the first awakening packet, the second awakening packet is sent to the WUR of the first device, so that the overall energy consumption of the first device is reduced. The flexibility of wireless communication between the AP and the terminal is improved.

In an optional implementation, the first wake-up packet includes wake-up indication information, where the wake-up indication information is used to indicate the second device to respond to the first wake-up packet in a wake-up packet manner, so that the second device confirms that the first wake-up packet is received by the second device, or confirms that the WUR of the second device has woken up the host transceiver module of the second device, that is, is in an ON operating state.

In an optional implementation, the wake-up indication information includes working state information of a WUR of the first device, the WUR of the first device receives a second wake-up packet, and the second wake-up packet is sent by the second device, which specifically includes: and the WUR of the first equipment receives a second wake-up packet sent by the second equipment according to the working state information of the WUR of the first equipment.

That is to say, the second device may select to respond to the first wake-up packet in a wake-up packet manner or in another manner other than the wake-up packet manner according to the operating state information of the WUR of the first device, thereby improving the flexibility of the communication method.

When the WUR of the first device is in a working state, the WUR of the first device receives a second wake-up packet sent by the second device according to the wake-up indication information, namely, when the second device knows that the WUR of the first device is in an ON state, feedback response in the form of the wake-up packet is confirmed, so that the power consumption of the first device is reduced, and meanwhile, the communication time is shortened.

In an alternative implementation, the second wake-up packet includes WUR identification information of the receiving device, such as an ID of the WUR or a receiving address of the WUR. The main transceiver module of first equipment communicates with the main transceiver module of the second equipment after awakening, specifically includes: the first equipment matches the WUR identification information of the first equipment with the WUR identification information of the receiving equipment; when the WUR identification information of the first device is matched with the WUR identification information of the receiving device, the first device determines the attribute information of the second device and communicates with the awakened main transceiver module of the second device through the main transceiver module of the first device, namely implicitly, the first device receives the second awakening packet, and power consumption in the communication process is effectively reduced.

In an optional implementation, the second wake-up packet includes address information sent by the second device, and the main transceiver module of the first device communicates with the main transceiver module of the second device after wake-up, which specifically includes: the first device communicates with the awakened main transceiver module of the second device through the main transceiver module of the first device according to the sending address information of the second device, namely, the first device receives the second awakening packet in an explicit mode, and power consumption in the communication process is effectively reduced.

In an optional implementation, the second wake-up packet includes data transmission direction information, and the main transceiver module of the first device communicates with the main transceiver module of the second device after wake-up, which specifically includes: the first device communicates with the main transceiver module of the awakened second device through the main transceiver module of the first device according to the data transmission direction information, that is, the first device receives the second awakening packet in another mode, so that the power consumption in the communication process is effectively reduced.

In an optional implementation, the second wake-up packet includes identification information of a cell of the second device, and the main transceiver module of the first device communicates with the main transceiver module of the second device after wake-up, which specifically includes: the first device communicates with the awakened main transceiver module of the second device through the main transceiver module of the first device according to the identification information of the cell of the second device, namely, the first terminal receives the second awakening packet in another mode, so that the power consumption in the communication process is effectively reduced.

In an optional implementation, the second wake-up packet further includes first indication information, where the first indication information is used to indicate that the primary transceiver module of the second device has been woken up, so that at least one third terminal, other than the first device, associated with the second device communicates with the woken-up primary transceiver module of the second device through the primary transceiver module of the at least one third device according to the first indication information, and since the first indication information indicates that the primary transceiver module of the third device has been woken up to the at least one second terminal, signaling overhead of the third device sending the wake-up packet to the second device is reduced, thereby reducing signaling overhead of the third device, and effectively shortening communication time.

In an optional implementation, the second wake-up packet further includes a broadcast address, so that the WUR of the first device and the WUR of the at least one third device receive the second wake-up packet and communicate with the awakened master transceiver module of the second device through the master transceiver module of the first device and the master transceiver module of the at least one third device, respectively. Because the broadcast address is added to the second wake-up packet, all terminals can know that the main transceiver module of the second device is awakened, so that the signaling overhead of the third device for sending the wake-up packet to the second device is reduced, the signaling overhead of the third device is reduced, and the communication time is effectively shortened.

In an optional implementation, on the basis that the second wake-up packet includes the broadcast address, the second wake-up packet may not include the WUR identification information (e.g., the ID of the WUR or the WUR receiving address) of the first device, and at this time, by setting that the first device only receives the second wake-up packet sent by the second device, it can be considered that the second wake-up packet has received the first wake-up packet, so that the length of the second wake-up packet can be reduced, and the transmission time can be effectively shortened.

In an optional implementation, the second wake-up packet further includes a first time duration, where the first time duration is a working time duration of a main transceiver module of the second device, and the main transceiver module of the first device communicates with the main transceiver module of the second device after wake-up, and specifically includes: and the first equipment communicates with a main transceiver module of the second equipment through the main transceiver module of the first equipment according to the first duration. That is to say, in the first duration, the master transceiver module of the second device can communicate normally without being awakened again by the WUR of the second device, thereby reducing signaling overhead and shortening communication time.

In an optional implementation, the second wake-up packet further includes second indication information, where the second indication information is used to wake up at least one fourth device main transceiver module associated with the second device, so that the main transceiver module of the first device and the main transceiver module of the at least one fourth device respectively communicate with the main transceiver module of the second device.

And the WUR of the second equipment awakens the main transceiver module of the second equipment according to the first awakening packet. The second device sends a second wake-up packet to the WUR of the first device for responding to the first wake-up packet. And the awakened main transceiver module of the second equipment is communicated with the main transceiver module of the first equipment. According to the communication method, after receiving the first wake-up packet, the second device sends the second wake-up packet to the WUR of the first device, so that the overall energy consumption of the first device is reduced. The flexibility of wireless communication between the AP and the terminal is improved.

In an optional implementation, the first wake-up packet includes wake-up indication information, where the wake-up indication information is used to instruct the second device to respond to the first wake-up packet in the form of a wake-up packet, so as to enable the second device to acknowledge the first wake-up packet, that is, to acknowledge that the second device receives the first wake-up packet, or to acknowledge that the WUR of the second device has woken up the host transceiver module of the second device, that is, in an ON operating state.

And when the WUR of the first equipment is in a working state, the first equipment sends a second awakening packet to the WUR of the second equipment according to the awakening indication information.

That is to say, the second device may select to respond to the first wake-up packet in a wake-up packet manner or in another manner other than the wake-up packet manner according to the operating state information of the WUR of the first device, thereby improving the flexibility of the communication method. The power consumption of the first device is reduced and the communication time is also shortened.

In an optional implementation, the second wake-up packet further includes a broadcast address, so that the first device and the at least one third device receive the second wake-up packet and communicate with the second device after wake-up through the main transceiver module of the first device and the main transceiver device of the at least one third device, respectively, and since the broadcast address is added to the second wake-up packet, all terminals can know that the main transceiver module of the second device is woken up, so that signaling overhead of the third device sending the wake-up packet to the second device is reduced, signaling overhead of the third device is reduced, and communication time is effectively shortened.

Detailed Description

The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

The technology described in the present invention can be applied to a Long Term Evolution (LTE) system, or other wireless communication systems using various wireless access technologies, such as cdma, fdma, tdma, ofdma, single carrier fdma, and the like. Furthermore, the method can also be applied to a subsequent evolution system using the LTE system, such as a fifth generation 5G system or a New Radio (NR) system. It should be noted that the terms "network" and "system" are often used interchangeably in the present invention, but those skilled in the art can understand the meaning.

The communication method provided by the present invention can be applied to a WLAN system, which can include at least one terminal and a network device, as shown in fig. 2.

The terminal may include various handheld devices having a wireless communication function, vehicle-mounted devices, Wearable Devices (WD), computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), Mobile Stations (MS), terminals (terminal), terminal equipment (terminal), Stations (STA), and the like.

The network device is a device deployed in a radio access network to provide a wireless communication function for a terminal, and the network device may include various forms of macro base stations, micro base stations, relay stations, access points (including terminals that turn on a hot spot function), and the like. For convenience of description, the network devices providing the wireless communication function may be collectively referred to as an access point AP in the present invention.

In fig. 2, both terminal STA1 and terminal STA2 may include a host transceiver module (e.g., an 802.11 host transceiver module) and a WUR, where STA1 and STA2 may have the same or different functions, e.g., STA1 may have a WiFi hotspot function, and STA2 may not have the WiFi hotspot function. It is worth noting that the AP may also be configured with WURs in order to reduce device power consumption.

AP, STA1, and STA2 may communicate wirelessly with each other, i.e., AP may communicate wirelessly with STA1 and STA2, and STA1 and STA2, respectively.

In a first scenario, when the AP has data to perform downlink communication, the AP may send a first wake-up packet to the WUR of the STA1 and/or the STA2, wake up the host transceiver module of the STA1 and/or the STA2, and send a second wake-up packet to the WUR of the AP after the wake-up by the STA1 and/or the STA2, so as to respond to the first wake-up packet, that is, the second wake-up packet is an acknowledgement packet of the first wake-up packet. The WUR of the AP, upon receiving the second wake-up packet, communicates data with the host transceiver module of STA1 and/or STA2 after the wake-up.

In scenario two, when STA1 and/or STA2 has data to perform uplink communication, STA1 and/or STA2 sends a first wake-up packet to the AP to wake up the host transceiver module of the AP, and the awakened AP sends a second wake-up packet to the WUR of STA1 and/or STA2 to respond to the first wake-up packet. After the WUR of STA1 and/or STA2 receives the second wake-on packet, the WUR communicates with the host transceiver module of the AP after wake-on

In a third scenario, when STA1 turns on the hotspot function, STA1 may send a first wake-up packet to the WUR of STA2, wake up the host transceiver module of STA2, and STA2 after wake-up sends a second wake-up packet to the WUR of the AP, so as to respond to the first wake-up packet. The primary transceiver module of STA1, upon receiving the second wake-up packet, performs data communication with the awakened STA 2.

It should be noted that STA1 or STA2 may send the second wake-up packet through the host transceiver module of STA1 or STA2 (i.e., adjust the data sent by the host transceiver module into data in the WUR frame format), may also send the second wake-up packet through an independent transmitter configured in STA1 or STA2 and having the WUR frame format, and may also send the second wake-up packet through other manners, which is not limited herein.

Because the energy consumption of the WUR during working is far lower than that of the main transceiver module during working, the terminal or AP waiting for feedback starts the WUR, and the energy consumption for receiving the second wake-up packet (response) is the least, so that the energy consumption of the system is integrally reduced.

In an application scenario of the mobile AP, the STA1 may turn on the hotspot function as the mobile AP to provide a WiFi hotspot, and the energy consumption of the STA1 needs to be considered. Specifically, the mobile AP configured with WUR may preset a certain time period to turn OFF (OFF) the host and turn ON (ON) the WUR.

Correspondingly, when the mobile AP is in the working state of the master transceiver module OFF and WUR ON, and when the non-AP station (STA2) associated under the mobile AP performs uplink (english: uplink) communication with the mobile AP, the non-AP station needs to transmit a wake-up packet first, and after receiving the wake-up packet, the WUR of the mobile AP wakes up its own master transceiver module and responds in the manner of the wake-up packet, thereby preparing to serve the non-AP station of the own cell. The service described herein includes receiving uplink data (not limited to a data frame, but also a management frame or a control frame) transmitted by the non-AP station, and also includes transmitting downlink data to the non-AP station by the mobile AP.

Fig. 3 is a schematic structural diagram of a WLAN system according to an embodiment of the present invention. As shown in fig. 3, the WLAN system may include a first device and a second device.

The first device may be the AP or STA of fig. 2 and, correspondingly, the second device may be the STA or AP of fig. 2. The first device sends a first wake-up packet to the WUR of the second device, and after the WUR of the second device receives the first wake-up packet, the WUR of the second device sends a trigger signal to the master transceiver module of the second device so as to wake up the master transceiver module of the second device.

The second device sends a second wake-up packet to the WUR of the first device for responding to the first wake-up packet, so that the first device confirms that the master transceiver module of the second device has been awakened. The main transceiver module of the first device transmits data to the main transceiver module of the second device for communication.

In the following, a detailed description is given by taking a scenario two, in which the first device is a first terminal STA and the second device is an AP as an example.

Fig. 4 is a signaling interaction diagram of a communication method according to an embodiment of the present invention. As shown in fig. 4, the method may include:

step 410, the first terminal generates a first wake-up packet.

When the first terminal has data to send to the AP, that is, the first terminal is to perform uplink communication, the first terminal generates a first wake-up packet to confirm that the operating state of a main transceiver module (e.g., 802.11 main transceiver module) of the AP is an ON state.

Step 420, the first terminal sends a first wake-up packet to the wake-up receiver WUR of the AP to wake up the host transceiver module of the AP.

The first wake-up packet may include WUR identification information of the AP, such as address information of the WUR, for instructing the AP to receive the first wake-up packet. The WUR identification information may be complete WUR identification information or partial WUR identification information, such as a complete Media Access Control (MAC) address, or a partial address that can distinguish MAC addresses.

Optionally, the first wake-up packet may further include wake-up indication information, where the wake-up indication information is used to instruct the AP to respond to the first wake-up packet by using the wake-up packet, where the response may be a wake-up acknowledgement for the first wake-up packet, where the "wake-up acknowledgement" may refer to an acknowledgement that the AP receives the first wake-up packet, or an acknowledgement that the WUR of the AP has woken up the host transceiver module of the AP, that is, is in an ON operating state.

Fig. 5 is a schematic structural diagram of a wake-up packet. As shown in fig. 5, the wake-up packet may include a preamble field and a payload field of the legacy 802.11.

In one example, in conjunction with the structure of fig. 5, the wake-up indication information may occupy 1bit (bit) in the payload field, that is, a value of 1bit indicates that the AP responds to the first wake-up packet by using the wake-up packet, and a value of 0 indicates that the AP responds to the first wake-up packet by using another method other than the wake-up packet;

alternatively, a value of 0 may indicate that the AP responds to the first wake-up packet with a wake-up packet, and a value of 1 may indicate that the AP responds to the first wake-up packet with a manner other than the wake-up packet, e.g., the AP sends a wake-up acknowledgement packet to the first terminal with a host transceiver module of the AP, where the acknowledgement packet is in a non-WUR frame format.

It can be understood that, according to actual design requirements, the wake-up indication information may also occupy multiple bits in the payload field, and a combination of the multiple bits is used to indicate that the AP is instructed to respond to the first wake-up packet by using the wake-up packet, which is not limited herein.

Optionally, the wake-up indication information may include the operating state information of the WUR and/or a main transceiver module (mainradio) of the first terminal.

If the WUR of the first terminal is OFF and the main radio frame is ON, the AP shall reply to the wakeup confirm in the format of the main radio frame, and if the WUR of the first terminal is ON and the main radio frame is OFF, the AP shall reply to the wakeup confirm in the format of the WUR frame (in the form of a wakeup packet). That is, the AP may select to respond to the first wake-up packet in a wake-up packet manner or respond to the first wake-up packet in another manner other than the wake-up packet manner according to the operating state information of the WUR of the first terminal, thereby reducing power consumption of the first terminal and shortening communication time.

The working state information of the WUR of the first terminal and the working state information of the main transceiver module can be carried by a newly-established first field in a load domain; other fields (e.g., reserved field, etc.) in the first wake-up packet may also be multiplexed to carry, and the field occupied for the convenience of this description is also referred to as the first field.

Alternatively, the first field may contain 1bit, e.g., 0 indicates WUR ON, main radio off of the first terminal; 1 indicates WUR OFF, main radio ON of the first terminal.

Alternatively, the first field may also contain 2 bits, e.g., 00 indicates WUR OFF, mainradio OFF, 01 indicates WUR OFF, main radio ON, 10 indicates WUR ON, main radio OFF, 11 indicates WURON, main radio ON for the first terminal.

It should be understood that the above-mentioned mapping between the number of bits included in the first field and the specific indication content is only an example, and other forms of mapping between the number of bits included in the first field and the specific indication content may also be available according to actual needs, and the embodiment of the present invention is not limited herein.

Step 430, the AP sends a second wake-up packet to the first terminal according to the first wake-up packet, so as to respond to the first wake-up packet.

Before step 130 is executed, after the WUR of the AP receives the first wake-up packet sent by the first terminal, the AP matches the WUR identification information in the first wake-up packet with the identification information of the WUR of the AP, and wakes up the host transceiver module of the AP according to the matching result.

And then, the AP sends a second wake-up packet to the first terminal according to the wake-up indication information in the first wake-up packet so as to respond to the first wake-up packet.

It can be understood that, by initializing the communication specification of the AP, that is, by specifying that the AP responds to the received wake-up packet in the wake-up packet manner after receiving the wake-up packet, a second wake-up packet may also be sent to the first terminal, and for the specific operation of the specification, the embodiment of the present invention is not limited.

And 440, the first terminal performs data communication with the awakened main transceiver module of the AP through the main transceiver module of the first terminal according to the second awakening packet.

The first terminal determines attribute information of the AP according to the received second wake-up packet, where the attribute information of the AP may include address information of the AP, cell information of the AP, data transmission direction information of the AP, and the like, and the main transceiver module of the first terminal performs data communication with the determined main transceiver module of the AP.

Optionally, the second wake-up packet may include WUR identification information of the receiving device, such as an ID of the WUR or a receiving address of the WUR.

The first terminal matches the WUR identification information of the first terminal with the WUR identification information of the receiving device, when the WUR identification information of the first terminal is matched with the WUR identification information of the receiving device, the first terminal determines the attribute information of the AP, and performs data communication with the determined main transceiver module of the AP through the main transceiver module of the first terminal, so that the first terminal further receives the second wake-up packet, and power consumption in the communication process is effectively reduced.

When the WUR identification information of the first terminal is not matched with the WUR identification information of the receiving device, the first terminal considers that the second wake-up packet is not received (the acknowledgement packet of the first wake-up packet is not received), that is, the first terminal considers that the master transceiver module of the AP is not woken up, and at this time, the first terminal may send the first wake-up packet to the AP again or continue to wait for the second wake-up packet sent by the AP.

It may be specified that, when the first terminal receives the receiving address included in the second wake-up packet as the receiving address of the first terminal WUR, it may regard this as a wake-up acknowledgement that the second wake-up packet is a first wake-up packet. That is, the function of the second wake-up packet including the wake-up acknowledgement is implicitly indicated by the ID of the WUR or the reception address of the WUR.

Further, the second wake-up packet may also include the function of wake-up acknowledgement by explicitly indicating that the second wake-up packet includes wake-up acknowledgement. And configuring an indication information field in the second wake-up packet, wherein the indication information field indicates that the function of the second wake-up packet is wake-up confirmation. For example, a specific wake-up ID or receiving address may be used to indicate that the function of the second wake-up packet is wake-up acknowledge.

Optionally, the second wake-up packet may include transmission address information of the AP, such as a MAC address.

The first terminal determines the attribute information of the AP according to the sending address information of the AP, and communicates with the awakened AP through the main transceiver module of the first terminal, namely, the first terminal receives the second awakening packet in an explicit mode, so that the power consumption in the communication process is effectively reduced.

Alternatively, the second wake-up packet may include data transmission direction information, such as an Uplink (UL) transmission direction or a Downlink (DL) transmission direction.

The first terminal determines the attribute information of the AP according to the data transmission direction information, and communicates with the awakened AP through the main transceiver module of the first terminal, namely, the first terminal receives the second awakening packet in another mode, so that the power consumption in the communication process is effectively reduced.

Optionally, the second wake-up packet may include identification information of a cell of the AP, such as a Basic service set color (BSS color) of the cell.

The first terminal determines the attribute information of the AP according to the identification information of the cell of the AP, and communicates with the awakened AP through the main transceiver module of the first terminal, namely, the first terminal receives the second awakening packet in another mode, so that the power consumption in the communication process is effectively reduced.

In one example, as shown in fig. 6, taking the state of the AP being main radio OFF and WUR ON as an example, when the first terminal has uplink data to transmit, the first terminal sends a first wake-up packet to the AP, where the first wake-up packet includes an instruction to wake up the main radio of the AP. At this time, the WUR of the first terminal remains in the working state and waits for the AP to reply the acknowledgement frame for the first wake-up packet.

After the WUR of the AP receives the first wake-up packet, the main radio of the AP is woken up. The AP sends a second wake-up packet as a wake-up acknowledgement for the first wake-up packet. And after receiving the second wake-up packet, the first terminal confirms that the main radio of the AP wakes up. And the first terminal sends data to main radio of the AP so as to carry out communication.

It is understood that the communication method of scenario two is just one specific implementation, and scenario one and scenario three are also applicable to this specific implementation.

That is to say, there may be other implementation manners for the communication methods of the scene one, the scene two, and the scene three, and this is not limited in this embodiment of the present invention.

In the communication method of the above embodiment of the present invention, after receiving the first wake-up packet, the AP sends the second wake-up packet to the WUR of the first terminal, so that the overall energy consumption of the first terminal is reduced. Thereby improving the flexibility of wireless communication between the AP and the terminal.

Fig. 7 is a signaling interaction diagram of another communication method according to an embodiment of the present invention. As shown in fig. 6, the method may include:

step 710, the first terminal generates a first wake-up packet.

And 720, the first terminal sends a first wake-up packet to the wake-up receiver WUR of the AP to wake up the master transceiver module of the AP.

The configuration information of the first wake-up packet may be configured in combination with the frame structure of fig. 5 in step 420, which is not described herein again.

If the WUR of the first terminal is OFF and the main radio frame is ON, the AP shall reply to the wakeup confirm in the format of the main radio frame, and if the WUR of the first terminal is ON and the main radio frame is OFF, the AP shall reply to the wakeup confirm in the format of the WUR frame (in the form of a wakeup packet).

That is, the AP may select whether to respond to the first wake-up packet in the wake-up packet or in another manner other than the wake-up packet according to the operating state information of the WUR of the first terminal.

Step 730, the AP sends a second wake-up packet according to the first wake-up packet broadcast for responding to the first wake-up packet and indicating to at least one second terminal associated with the AP that the primary transceiver module of the AP has been woken up.

Before step 730 is executed, after the WUR of the AP receives the first wake-up packet sent by the first terminal, the AP matches the WUR identification information in the first wake-up packet with the identification information of the WUR of the AP, and wakes up the host transceiver module of the AP according to the matching result.

It can be understood that by initializing the AP, the AP is configured to respond to the first wake-up packet in the form of a wake-up packet after receiving the first wake-up packet. The embodiment of the present invention is not limited to the specific operation of the setting.

And 740, the first terminal and the at least one second terminal perform data communication with the awakened main transceiver module of the AP through the main transceiver module of the first terminal and the main transceiver module of the at least one second terminal according to the second awakening packet.

The second wake-up packet may include a response to the first wake-up packet and first indication information.

In combination with the content in step 440, the response to the first wake-up packet may be to determine the attribute information of the AP according to the WUR identification information of the receiving device (e.g., the ID of the WUR or the receiving address of the WUR), the sending address information (e.g., the MAC address) of the AP, the data transmission direction information (e.g., the uplink or downlink transmission direction), or the identification information of the cell of the AP, so as to confirm that the AP receives the first wake-up packet. The first indication information is used for indicating that the main transceiver module of the first indication information is awakened to at least one second terminal associated with the AP except the first terminal so that the AP and the at least one second terminal associated with the AP can communicate with each other, therefore, the signaling overhead of the second terminal is reduced, and the communication time is effectively shortened.

Optionally, the second wake-up packet may further include a broadcast address.

And the AP sends a second awakening packet in a broadcast mode according to the broadcast address, so that the first terminal and at least one second terminal receive the second awakening packet. Since the second wake-up packet includes a response to the first wake-up packet, the second wake-up packet may notify the at least one second terminal that the main transceiver module of the own (AP) has been awakened, thereby enabling the first terminal and the at least one second terminal to communicate with the AP, respectively. Wherein the broadcast address may be set in an ID field of the WUR or a WUR reception address field.

Optionally, on the basis that the second wake-up packet includes the broadcast address, the second wake-up packet may not include the WUR identification information (e.g., the ID of the WUR or the WUR receiving address) of the first terminal, and at this time, by setting that the first terminal can consider that the AP has received the first wake-up packet as long as the second wake-up packet sent by the AP is received, even if the second wake-up packet does not include the ID (or the WUR receiving address) of the corresponding receiving terminal, the second wake-up packet at this time is an implicit response to the first wake-up packet. The structure of the second awakening packet can reduce the length of the second awakening packet and effectively shorten the transmission time. The above-mentioned setting process is not limited in the embodiments of the present invention.

Optionally, the second wake-up packet may further include the first duration.

The first duration is the working duration of the main transceiver module of the AP after awakening. That is to say, in the first duration, the master transceiver module of the AP may communicate normally without being awakened again by the WUR of the AP, so that the first terminal communicates with the master transceiver module of the AP according to the first duration. The structure of the second wake-up packet reduces signaling overhead and shortens communication time.

After the first terminal receives the second wake-up packet sent by the AP, the first terminal knows that the main transceiver module of the AP is woken up, after recognizing the first time length, the first terminal performs normal data communication with the AP within the first time length, and if the communication between the first terminal and the AP is not finished when the first time length is finished, the first terminal can send the wake-up packet to the AP again so as to wake up the main transceiver module of the AP to perform data communication again.

It should be noted that the time period of the first duration may be preset according to actual needs or types of communications.

Optionally, the second wake-up packet may further include a second duration.

The second duration is a suspension duration during which the at least one second terminal does not communicate with the AP. That is, the at least one second terminal does not perform data communication with the AP until the second duration, and resumes data communication with the AP after the second duration. Wherein the second terminal is a terminal other than the first terminal that can be associated with the AP. The structure of the second wake-up packet can avoid at least one second terminal competing with the first terminal for a channel, so that the first terminal can independently perform data communication with the AP within the second time length, and the data communication time between the first terminal and the AP is shortened.

It should be noted that the time period of the second duration may also be preset according to actual needs or types of communications.

In conjunction with the block diagram shown in fig. 8, the second scenario may include the following two examples:

in one example, taking the state that the AP is in main radio OFF and WUR ON as an example, when the first terminal has uplink data to transmit, the first terminal sends a first wake-up packet to the AP, where the first wake-up packet includes an indication of main radio for waking up the AP. At this time, the WUR of the first terminal remains in the working state and waits for the AP to reply the acknowledgement frame for the first wake-up packet.

After the WUR of the AP receives the first wake-up packet, the main radio of the AP is woken up. The AP sends a second wake-up packet, which includes a broadcast address, sends a response to the first terminal, and indicates to a second terminal associated with the AP that the mainradio of the AP has been woken up. And the first terminal receives the second wake-up packet to confirm that the main radio of the AP wakes up, contend for a channel and prepare to send uplink data to the main radio of the AP. And associating other second terminals under the AP, and after receiving the second wake-up packet and confirming that the main radio of the AP is awakened, the other second terminals can compete for the channel to prepare to send uplink data to the main radio of the AP.

In another example, taking the working state of the AP being main radio OFF and WUR ON as an example, when the first terminal has uplink data to transmit, the first terminal sends a first wake-up packet to the AP, where the first wake-up packet includes an indication of main radio for waking up the AP. At this time, the WUR of the first terminal remains in the working state and waits for the AP to reply to the acknowledgement packet of the first wake-up packet.

After the WUR of the AP receives the first wake-up packet, the main radio of the AP is woken up. And the AP sends a second wake-up packet as an acknowledgement packet of the first wake-up packet and simultaneously informs other second terminals that the main radio of the AP is awakened. The second wake-up packet includes a second duration. And after receiving the second wake-up packet, the first terminal confirms that the main radio of the AP wakes up and prepares to send uplink data to the main radio of the AP. And associating other second terminals under the AP, confirming that the main radio of the AP is awakened after receiving the second awakening packet, competing for the channel after a second time length, and preparing to send uplink data to the main radio of the AP.

It is understood that the second wake-up packet may include the first duration or the second duration, and may also include the first duration and the second duration.

When the first duration and the second duration in the second wake-up packet exist at the same time, in order to reduce signaling overhead and shorten communication time, a time period of the first duration may be set to be greater than a time period of the second duration.

It should be noted that the above two examples are also applicable to scenario one and scenario three, and the embodiments of the present invention are not described herein again.

In the above embodiment of the present invention, after receiving the first wake-up packet, the AP sends the second wake-up packet to the WUR of the first terminal, so that the overall energy consumption of the first terminal is reduced, and by adding a broadcast address to the second wake-up packet, a process of the second terminal sending the wake-up packet to the AP to trigger the wake-up of the main transceiver module of the AP is reduced, signaling overhead of the system is reduced, communication time is shortened, and communication time is further effectively controlled by configuring the first duration and/or the second duration in the second wake-up packet. The method can be applied to multiple scenes, so that the flexibility of wireless communication between the AP and the terminal is improved.

Fig. 9 is a signaling interaction diagram of another communication method according to an embodiment of the present invention. As shown in fig. 9, the method may include:

step 910, the first terminal generates a first wake-up packet.

And step 920, the first terminal sends a first wake-up packet to a wake-up receiver WUR of the AP to wake up a host transceiver module of the AP.

If the WUR of the first terminal is OFF and the main radio frame is ON, the AP shall reply to the wakeup confirm in the format of the main radio frame, and if the WUR of the first terminal is ON and the main radio frame is OFF, the AP shall reply to the wakeup confirm in the format of the WUR frame (in the form of a wakeup packet). That is, the AP may select whether to respond to the first wake-up packet in the wake-up packet or in another manner other than the wake-up packet according to the operating state information of the WUR of the first terminal.

Step 930, the AP sends a second wake-up packet to the first terminal and at least one third terminal associated with the AP according to the first wake-up packet, for responding to the first wake-up packet and waking up the at least one third terminal.

Before step 930 is executed, after the WUR of the AP receives the first wake-up packet sent by the first terminal, the AP matches the WUR identification information in the first wake-up packet with the identification information of the WUR of the AP, and wakes up the host transceiver module of the AP according to the matching result.

And 940, the first terminal and the awakened at least one third terminal perform data communication with the awakened main transceiver module of the AP through the main transceiver module of the first terminal and the main transceiver module of the at least one third terminal according to the second awakening packet.

The second wake-up packet may include a response to the first wake-up packet and second indication information.

In combination with the content in step 440, the response to the first wake-up packet may refer to determining the attribute information of the AP according to the WUR identification information of the receiving device (e.g., the ID of the WUR or the receiving address of the WUR), the sending address information (e.g., the MAC address) of the AP, the data transmission direction information (e.g., the uplink or downlink transmission direction), or the identification information of the cell of the AP, so as to confirm that the AP receives the first wake-up packet.

Optionally, the second wake-up packet may further include WUR identification information of the at least one third terminal, such as a WUR ID or a WUR reception address, so that the at least one third terminal receives the second wake-up packet to wake up the master transceiver module of the at least one third terminal.

Since the second wake-up packet includes a response to the first wake-up packet, the second wake-up packet may notify the at least one third terminal that the main transceiver module of the own (AP) has been awakened, so that the main transceiver module of the first terminal and the main transceiver module of the at least one third terminal communicate with the main transceiver module of the awakened AP, respectively.

Optionally, the second wake-up packet may also not include the WUR identification information of the first terminal (e.g., the ID or WUR receiving address of the WUR), and at this time, the AP may be considered to receive the first wake-up packet by setting that the first terminal only receives the second wake-up packet sent by the AP, even if the second wake-up packet does not include the ID (or WUR receiving address) of the WUR of the corresponding receiving terminal, the second wake-up packet at this time is an implicit response to the first wake-up packet. The structure of the second awakening packet can reduce the length of the second awakening packet and effectively shorten the transmission time. The above-mentioned setting process is not limited in the embodiments of the present invention.

In conjunction with the block diagram shown in fig. 10, the second scenario may include the following two examples:

After the WUR of the AP receives the first wake-up packet, the main radio of the AP is woken up. The AP sends a second wake-up packet, the second wake-up packet comprising a broadcast address and sending a response to the first terminal, the second wake-up packet further comprising second indication information for waking up one or more third terminals associated with the AP.

And the first terminal receives the second wake-up packet and confirms that the main radio of the AP wakes up. And preparing to send uplink data to main radio of the AP. And after receiving the second wake-up packet, one or more third terminals wake up respective main radios to prepare for receiving downlink data from the AP. After the AP receives the data of the first terminal, the AP sends downlink data to the mailradio of one or more third terminals.

It should be noted that the above example can also be applied to scenario one and scenario three, and the embodiments of the present invention are not described herein again.

In the above embodiment of the present invention, after receiving the first wake-up packet, the AP sends the second wake-up packet to the WUR of the first terminal, so that the overall energy consumption of the first terminal is reduced, and the WUR identification information of at least one third terminal is configured in the second wake-up packet, so as to wake up the host transceiver module of the corresponding third terminal, thereby reducing the signaling overhead of the system and shortening the communication time.
